Description

ROAD STRUCTURE FOR REDUCING POLLUTION EMITTED BY MOVING VEHICLES

FIELD OF THE INVENTION

This invention relates to a road structure for reducing pollution emitted by moving vehicles on the road. The road structure is useful for transferring energy from electrical power lines to moving vehicles on the road, without electrical connection between the electrical power lines and the moving vehicle, so as to reduce use of the vehicle engine and thus to reduce pollutant emission by the moving vehicle.

STATE OF THE ART IN THE FIELD

It is known that the energy is required for the movement of vehicles, for example, cars; trucks; motorcycles and all other two or more wheeled vehicles. Generally each vehicle is a standalone unit having an engine provided therewith for generating the required energy needed for moving the vehicle from one place to other place. At all times the engine needs to generate energy to move the entire vehicle. The vehicle engines, mostly internal combustion engines, have low thermal efficiency, by and large well below 50%. The large number of vehicles on the road, each generating its own energy requirement at low efficiency, leads to considerable loss of energy producing material such as petroleum fuel. Also the net pollutant emission is high.

Battery operated electric vehicles do not pollute the environment. But battery operated vehicles require frequent recharging with operating distance on a single charge being limited to about 150 KM. Also recharge time during which the vehicle is in a stationary state is long. Further, batteries are heavy and increases the overall vehicular weight and energy consumption. Therefore with the present state of battery technology battery operated vehicles are in limited usage and do not overcome the pollution problem.

There are disadvantages associated with all the known vehicles which are widely in use. One of the main disadvantages is that each vehicle emits pollutants causing harm to the environment.

Therefore, there is a need of a road structures which enable part or whole of the energy requirement of each vehicle to be met from a centralized source where energy is generated in bulk with high efficiency in place of each vehicle generating its energy demand at low efficiency. There is also the need for that teach vehicle on the road to retain maneuverability and not be restricted exclusively to paths set by the central energy providing structures such as overhead electric power lines.

OBJECTS OF THE INVENTION

Therefore an object of the present invention is to provide a road structure for reducing pollution emitted by the moving vehicles on roads and thus to avoid the disadvantages associated with the prior art.

Another object of the present invention is to provide a road structure for reducing overall demand of energy generating fuels and thereby the net pollution emissions from vehicles on the road.

Yet another object of the present invention is to provide a road structure having means to transfer energy from electrical power lines to the vehicle in mechanical energy form.

Still another object of the present invention is to provide a road structure which leads to conversion of the potential energy stored in the vehicle to kinetic energy thereby propelling the vehicle.

A further object of the present invention is to provide a road structure which transfers energy from electrical power lines to the vehicle in mechanical kinetic energy form by a vehicle tow system to eliminate / reduce petroleum fuel demand by the vehicle engine and therefore eliminating / reducing pollution generated by moving vehicles on a normal road structure.

DETAILED DESCRIPTION OF THE INVENTION

A road structure for reducing pollution by moving vehicles is herein described with numerous specific details so as to provide a complete understanding of the invention. However these specific details are exemplary details and should not be treated as the limitation to the scope of the invention. The invention may be performed with slight modifications. Throughout this specification the word "comprise" or variations such as "comprises or comprising", will be understood to imply the inclusions of a stated element, integer or step, or group of elements, integers or steps, but not the exclusions of any other element, integer or step or group of elements, integers or steps.

Referring to the drawings, particularly figure 1 , road structure with vehicle escalating means of the present invention is shown. The road structure in cities, by and large, comprises multilane roads so as to allow to run the vehicles only in one direction on one side of the road and to run the vehicles in the opposite direction on the other side of the road. The road structure of the present invention, shown for left hand drive system which with change in direction is applicable to right hand drive system, comprises an escalating means comprising plurality of segments like entry segment, upslope segment and down slop segment [1 , 2, 3], respectively, for one traffic lane, for example for left hand side lane, with vehicle [4] moving forward from segment (1] of the lane towards segment [3] of the lane to enter an intersection [9]. On the other lane with segments [5, 6, 7] the vehicle [8] is shown on the lane segment [7] moving towards the intersection [10]. The vehicle [8] has traversed the lane segments [5, 6] and thereafter is in lane segment [7]. The two tanes are separated by a road divider [11]. Roads [12, 13] are cross^¬ roads at intersection [9] and roads [14, 15] are cross-roads at intersection [10]. Each of the cross-roads have segments similar to [1 , 2, 3].

An embodiment of the present invention is to have a major portion of the lane sloping downwards as shown in segments [3, 7] in the direction of movement of the vehicle. The segment of the lane which has a downward slope is proximal to the intersection towards which the vehicle is moving. The relative lengths of the segments of the lane are such that the downward sloping segment constitutes the major portion of the lane from one intersection to another. The downslope segment comprises maximum height adjacent to the entry point and start sloping down gradually and finishes at the next intersection such that to provided energy to the vehicle automatically due to downward slope. The downward slope [3, 7] is in the direction of the vehicle movement. Since the ground terrain is horizontal such slope configuration is realized by elevating the road immediately following entry from an intersection as represented by segment [2] following intersection [10] and thereafter providing the down slope segment [3] before entry into the next intersection [10]. On the other lane the elevation [6] is constructed following entry from intersection [9] and the down slope [7] is before the entry to the next intersection [ 0].

The said elevation is obtained by providing a segment of up slope [2] following the entry segment [1]. On the other lane the segment of up slope [6] follows the entry segment [5]. The segment [1] following intersection [10] and segment [5] following intersection [9] too have a very low up slope gradient. The segment [2] and segment [6] have a high up slope gradient.

The energy requirement of a vehicle as well as the pollution emission is markedly reduced when moving down a slope as compared to when moving on horizontal ground. The downward slope road structure segment [3] and segment [7] serve to achieve such a reduction in vehicular energy requirement. That is the vehicle when at the top of an elevated segment has high potential energy. When coming down slope the potential energy is converted to kinetic energy by the gravitational forces of the earth. The kinetic energy thus realized propels the vehicle forward without drawing upon energy from the vehicle engine. In this situation the vehicle engine will be in low power generation mode consuming low amount of fuel and in turn the pollution emission is also low. For the purpose of reducing energy consumption and pollution by means of a down slope the vehicle is to go up slope first. But going upslope on a steep rise requires considerable energy production from the vehicle engine. Such high power generation by the vehicle engine, even for a short duration, is very energy inefficient and pollution producing. Many vehicles, especially battery operated electric vehicles, do not have the high power boost feature and would not be able to climb up the slope at the entry of the intersection.

Surprisingly it has been found that a contoured road structure at the entry of a lane following an intersection with an initial low gradient up slope segment [1] which is sufficiently long to accommodate the length of the longer vehicles plying on the , road followed by higher gradient up slope [2] merging into a curved elevation summit [16] followed by down slope [2] optimizes utilization of the momentum of the vehicle in escalating the vehicle. It has also been found that a drive structure in the form of a belt or chain [17] which closely fits the aforesaid contour of the road and moves in the direction of movement of the vehicle surprisingly helps to move the vehicle to the elevation summit [16] thereby storing potential energy in the vehicle. If there are multiple lanes for vehicular movement multiple belts each of the width of a single vehicle movement lane was found to be required. Experiments showed that if the belt is too wide and several vehicles run in parallel on the same belt or chain there is torsion in the belt with displacement and jamming of the belt.

Referring to figure 2, an elevation view in section of the escalating means is shown. The belt or chain [17] is in the form of a closed loop embedded in the belt or chain [17] there are inclined swivel plates [21] of triangular longitudinal section. The inclined swivel plates in a direction perpendicular to the direction of flow of traffic have widths more than the width of the tyres of the vehicles plying on the road. In the direction perpendicular to the flow of traffic the inclined swivel plates are placed with small spacing less than the width of the tyres of the vehicles plying on the road. A number of rows of such inclined swivel plates are placed on the belt or chain [17] all along the length of the closed loop. Each inclined swivel plate is secured through a hinged [27] (see Figure 3) to swing plates [26]. The swing plates [26] and hinges [27] are located on the trailing end of the inclined swivel plate [21] if considered from the direction of movement of vehicles [24]. The other end of the inclined swivel plate [21] have a spring leaf plate [28]. For retention and stability of the inclined swivel plates [21] a support plate [25] adhering to the belt or chain [17] is positioned. The leaf spring plate [28] on one end is fixed to the inclined swivel plate [21] and at the other end to the support plate [25]. The pre- stressing of the spring leaf plate [28] is such that spring leaf plate tends to maintain the inclined swivel plate [21] at an acute angle in relation to the support plate [25]. In such a position the combination of the inclined swivel plate and swing plates [26] would restrict the down slide of a vehicle wheel abutting with the inclined swivel plate as for example the wheel [22] on the rear of the vehicle [4]. When a wheel of a vehicle comes over the inclined swivel plate the weight of the vehicle brings in rotational torque to the spring leaf plate. The inclined swivel plate is pressed downwards in such a manner that the inclined swivel plate tends to become parallel to the support plate. The acute angle between the inclined swivel plate and the support plate falls to near zero. An inclined swivel plate so loaded is shown as [23]. In this state of the inclined swivel plate the vehicle wheel can roll over the inclined swivel plate without hindrance. The swing plate [26] and the hinges [27] provide freedom to the swing of the inclined swivel plate while at the same time giving retention force resisting sideward displacements and misalignment. As soon as the vehicle wheel crosses the inclined swivel plate and the weight of the vehicle is not pressing down on the inclined swivel plate, the spring leaf plate [28] exerts restoring torsional force bringing the inclined swivel plate back to an acute angle position relative to the support plate [25].

The continuous loop of the belt or chain [ 7] is moved, over the surface of the road and over a plurality of rollers [19] by means of electrical motors [20] placed under the road surface or at the side of the road and powered from main electric lines. Electrical voltage and currents come only to the electrical motors [20]. The electrical motors [20] are electrically insulated from the belt or chain [17]. There is thus no electricity coming to the belt or chain [17]; the road [1 ,2,3] and the vehicle [4, 8]. There is therefore complete electrical safety Such a form is in contrast with road trams and buses which draw electrical power from overhead lines into electrical motors placed on the vehicle. In such a vehicle if there is electrical leakage in the electrical motor installed within the vehicle there is electrocution hazard for the passengers of the vehicle. Moreover electrical leakage of the electrical motor installed on the vehicle may lead to electrical currents on the metal tram tracks. A pedestrian walking over the track may get electrocuted. The present invention totally overcomes such risks.

A vehicle coming near the cross-section first gets positioned over the low slope portion of the incline [1]. The Vehicle is moved by the belt or chain [17] towards the high up slope gradient part of the inclined road [2]. The vehicle may derive some power from its own engine drive but the main power in mechanical form comes from the electrical motor [20] placed under the road or at the side of the road. The vehicle thereafter moves up the steeper segment of the incline that is the road up slope [2]. The inclined swivel plates [21] swing down under the weight of the vehicle to allow unhindered movement of the vehicle toward the top of the incline. The swivel plates swing up when the wheel has passed and thereafter help to check downslope movement of the vehicle. Ultimately the vehicle crosses the summit [16] of the incline to the downward sloping portion of the road [3] leading to the next intersection [9]. Major part of the energy need for the vehicle to move up the incline is derived from the electrical power mains via the electrical motors placed under the incline and not from the engine of the vehicle. By this mechanism from the electrical power mains energy is transferred and stored as potential energy in the vehicle with the energy being obtained from the electrical power mains in electrical energy form and electromechanical conversion by means of the electrical motor [20]. The potential energy stored in the vehicle gets converted into kinetic energy as the vehicle moves down the slope [3] towards the next intersection. It is to be noted that between intersections more than one such up sloping incline may be positioned so that potential energy storage in the vehicle with the energy derived from the electrical power mains is replenished several times while moving from one intersection to the next intersection.

At each lane at an intersection there is optical imaging system, not shown in the figures, to track the passing of vehicles. Additional devices installed at the intersection include electrical measuring devices connected to the power line and to the electrical motors as well dynamic speed monitor on each motor. Further weight sensors may be placed on the inclined swivel plates. With the data from these sensing devices the energy transferred to each vehicle from the electrical power line is determined and the vehicle owner is charged accordingly on a prepaid or post-paid scheme.

In another embodiment of the invention the movement of vehicle up the incline may be mediated by means of a rope-like structure described in the following sections. As shown in Figure 4, between intersections on the road there is a rope-like structure [29] installed in the middle of each lane to transfer mechanical energy to vehicles [37]. The mechanical energy is derived from electrical power lines after conversion to mechanical energy form by means of roller with drive motor integrated [31] which are positioned below the surface of the road. The transfer is by electro-mechanical conversion performed below the road surface with no electrical connection between the power lines and the vehicle.

Referring to figure - 5, elevation and plan view of rope like structure is shown. The rope like structure comprises a rope provided in the middle of each lane from one intersection to the next, or if there are multiple upward inclines between intersections, from one incline to the next, there is a flexible rope- like structure [29] is installed in the form of a continuous loop and moves continuously in the direction [30] (see Figure 4). The rope-like structure [29] which may be made of metal or polymers or fibers or combinations, is placed over roller with drive motor integrated [31}. The rope-like structure [29] is positioned in a central groove [34] at the middle of the road. The rope-like structure [29] is at the centre of a sleeve [32, 33]. As detailed in the figure 5 a sleeve-rigid part [32] alternates with sleeve - flexible part [33]. Figure 4, for clarity, shows one sleeve-rigid part [32].

In one embodiment and as shown in figure 4, each vehicle is fitted with a rod [35] which can be manipulated from the vehicle driver seat. One end of the rod is hinged in swivel mode on the front chassis member of the vehicle. At the other end of the rod there is a clamp [36] which may be magnetic or non-magnetic. The claws of the clamp [36] hold on to a hook [41] positioned at the upper surface of the sleeve - rigid part. Figures 6 and 7 indicate the placement of the hook [41] on the sleeve - rigid part [32].

Since the sleeve - rigid part [32] and sleeve - flexible part [33] are firmly fixed to the rope-like structure [29], the sleeves will move in the same direction [30] as does the rope-like structure [29]. Therefore the hook [41] too moves in the direction [30] of the rope-like structure [29]. The clamp [36] and the rod [35] are pulled in the direction [30]. The rod [35] being linked to the vehicle [37], the vehicle is pulled forward in the direction [30]. Thus electrical energy from the electrical power lines is converted to mechanical energy by the combination of roller with drive motor integrated [31]. The mechanical energy is transferred to the rope like structure [29]. From the rope - like structure the mechanical energy is transferred to the vehicle through the sleeve-rigid part [32]; hook [41]; clamp [36]; and rod [35] combination to the vehicle [37], The vehicle moves forward even if the engine of the vehicle is turned off or in the idle mode. Hence pollution emission from the vehicle will be low or nil. Also fuel utilization will be low. Furthermore since the drive energy comes from electrical power supply which has high generation efficiency the energy efficiency of the overall system will be high.

Since the rod is hinged in swivel mode with the vehicle chassis the vehicle may be steered from side to side over a lane. However if the vehicle steers too far out of a lane as, for example to overtake another vehicle or turn to a side road the clamp [36] at the end of the rod [35] automatically releases. The vehicle is then free from the rope-like structure [29] and on its own engine power can move to another lane or to a side road. For overtaking a vehicle ahead, the driver voluntarily disengages the clamp performing the manipulation while sitting on the driver seat. The manipulator may have various forms, one of which could be a handle positioned near the steering wheel of the vehicle with links to the clamp. On disengaging the clamp [36] from the hook [41] the driver can overtake a vehicle ahead on the vehicle engine power. Then getting onto a lane again the driver can activate the clamp to grip a hook on a sleeve - rigid part. The vehicle engine may then be turned off or put on idle mode and the vehicle is pulled forward by the rope like structure. The traction power is derived from the electrical power supply through electro-mechanicat conversion and transfers. When vehicle brake is applied the clamp automatically releases from the hook [41] and the vehicle can slow down or stop even though the rope- like structure [29] underneath the vehicle would be moving.

The rod may be a factory fit in new cars or may be retro fitted easily to older cars. The rod has inbuilt tension sensor by means of which the pulling force applied by the sleeve on the rope-like structure may be monitored. The tension force multiplied by the distance over which the sleeve pulls the vehicle gives the energy provided to the vehicle from the electrical motors driven by the electrical power mains. Thus the energy provided to each vehicle may be quantitated and the vehicle owner charged in pre-paid or postpaid mode. In another embodiment of the invention the movement of the vehicle is done with the rod being fixed to a rear member of the vehicle chassis and a sleeve on the rope like structure pulling the rear section of the vehicle forward. In another embodiment of the invention the vehicle is pushed forward instead of being pulled forward. The transfer of energy from electrical motors to the vehicle may also be done by means other than that given in the description above. A travelling magnetic field may be established under the road surface which is to drag a magnetic material or a proper magnet fixed to the vehicle. The energy for establishing the travelling magnetic field is derived from electrical power mains. Another option is to have a vacuum suction force.

The width of the sleeve - rigid part [32] as well as the sleeve - flexible part [33] is designed to be more than the tyre width of three wheeler vehicles such as three wheeler auto-rickshaws and three wheeler goods carriers. All such vehicle have a brake on the central front wheel for emergency purpose besides the regular brake on the rear wheels. The front wheel brake is independent of the rear wheel brakes. For deriving energy from the rope like structure first the three wheeler vehicle needs to come over the rope like structure with the central front wheel positioned over either the sleeve - rigid part [32] or over the sleeve - flexible part [33] or straddling a part of one sleeve - rigid part and a sleeve - flexible part. Thereafter the central front wheel brake is to be applied. The sleeve then drags the front wheel forward and thereby the whole three wheeler vehicle is propelled forward even if the vehicle engine is turned off or put on idle mode. No special fixtures to the three wheeler vehicle is required for deriving assistance from the rope like structure.

For two wheeler vehicles there is an issue of "balance". Balance requires relative motion between the surface of support and the vehicle. For two wheeler vehicles therefore a rod rigidly fixed to the vehicle and perpendicular to the vehicle is required so that the two wheeler vehicle is positioned on the road at the side of the rope like structure and not on the moving sleeves.

Referring to figure 6, elevation and plan view of the sleeve are shown. The sleeve comprises a sleeve - rigid part [32] with the elevation view on top and plan view below. The rope-like structure [29] passes axially through the sleeve - rigid part [32] and the sleeve - rigid part is firmly fixed to the rope like structure. The hook [41] extends up to the surface of the road. The force exerted by the sleeve - rid part [32] on to the rod [35] leads to a reactive force exerted by the rod [35] which has a component vertical to the road surface. This component of the reactive force tends to lift the sleeve - rigid part [32] and dislodge the sleeve - rigid part from the road. To counter the lifting action the sleeve - rigid part [32] is positioned in a channel [42] (see Figure 7). The channel [42] is embedded in the central groove [34] located at the centre of each road lane. The sleeve - rigid part [32] slides within the cannel [42]. For smooth sliding and proper guiding action along curves of a road the sleeve - rigid part [32] is constructed with a set of rollers [38, 39, 40]. The horizontal roller on upper part of sleeve - rigid part [32] rolls on the inner surface of the channel located on the upper section of the sleeve - id part. These rollers resist the lifting of the sleeve - rigid part. The horizontal roller [40] on lower section of sleeve rigid part resists downward thrust exerted by the rod when the vehicle is moving down an incline on the road. The vertical roller [39] on sleeve- rigid part resists lateral displacements and facilitates sleeve - rigid part sliding action in curves of the road.

The sleeve - flexible part [33] is not directly linked to the rod [35] and is not subject to lifting forces such as that on the sleeve - rigid part [32]. Since the sleeve - flexible part [33] too slides within the channel [42] and in the event of a three wheeler vehicle wheel resting on the sleeve - flexible part [33] there is downward thrust on the sleeve - flexible part. For smooth action the sleeve -flexible part [33] too are provided with a set of horizontal rollers [43] as well as vertical rollers which are not shown in the figures.

On the road the both sleeve - rigid part [32] and sleeve - flexible part [33] pick up dirt. At the road intersection where the rope like structure [29] loops around and located below the ground, suction vacuum cleaners are installed to suck dirt out of the sleeves. Also the rollers are very lightly oiled by spray.

Another embodiment of the invention is the rope like structure to be in segments. The sleeve - rigid part serves as a joint between two sectional lengths of the rope like structure. With such a construction in case of evidence of partial breakdown of the rope like structure at any point, that particular sectional length of the rope like structure may be changed. Such a form leads to ease and cost of maintenance.

With the embodiments described electrical energy from supply lines after conversion to mechanical energy form is transferred safely to vehicles so that vehicle engines may be turned off or put in idle mode to reduce pollution and save petroleum fuel. The road slope structure shown in Figures 1 to 3 has the following sequence of energy transfer: electrical energy from electrical power supply mains, electromechanical conversion by electrical motor; storage of the transferred energy as potential energy in the vehicle; and automatic conversion to kinetic energy on the down slope segment of the road [3}. The central theme is potential energy build up for the vehicle.

The rope - like structure [29] shown in figures [4 - 7] has the following sequence of energy transfer, (i) electrical energy from electrical power supply mains, (ii) electromechanical conversion by electrical motor to kinetic energy of the rope-like structure; (iii) transfer of the kinetic energy from the rope - like structure to the vehicle by means of the rod and clamp linkage to build up the kinetic energy of the vehicle. The ratio of kinetic energy supplementation to the vehicle by the potential energy-kinetic energy conversion to direct kinetic energy input is in the range between 100. to 0: 100. The ratio will be one extreme of 100:0 when there is slope structure but either that the rope - like structure system has not been installed or there is failure of the rope - like structure or failure of electrical motors associated with the rope - like structure. The other extreme of the ratio being 0: 100 will obtain when either the slope structure has not been installed or there is failure in the belt or chain or of the electrical motors associated with the belt or chain system. When all structures are in place and operational the energy ratio will be range between the extremes.

Certain features of the invention have been described with reference to the example embodiments. However, the description is not intended to be construed in a limiting sense. Various modifications of the example embodiments as well as other embodiments of the invention, which are apparent to the persons skilled in the art to which the invention pertains, are deemed to lie within the spirit and scope of the invention.
