Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle balance control device, and more particularly to a vehicle in which the vehicle travels stably, for example, when traveling from a left or right curve or traveling up or down a slope. The present invention relates to a device devised so that stability can be improved and so-called “hydroplaning phenomenon (water curtain phenomenon)” can be suppressed.

[0002]

2. Description of the Related Art Some vehicles, for example, passenger vehicles are of the FR type (front engine / rear drive type). This is because the engine is mounted on the front part of the vehicle body, and the rotation generated by this engine is transmitted to the rear wheel side via a clutch, transmission, universal joint, differential, and thereby,
The vehicle travels by driving the rear wheels. Further, the vehicle is driven in a desired direction by steering the front wheels by a steering device including a steering wheel. In addition to the above-described FR system (front engine / rear drive system), there are vehicles of the FF system (front engine / front drive system) and the 4WD system (four-wheel drive system).

[0003]

According to the above-mentioned conventional configuration, there are the following problems. In other words, if the driver tries to drive the vehicle while turning a curve in the left-right direction by operating the steering device, for example, if the driver tries to turn left, the centrifugal force acts outward (in this case, right). In addition, a large force acts on the vehicle in that direction, and as a result, the right side of the vehicle sinks and the left side rises, and running stability is greatly impaired.
This is also the case when the vehicle is going to turn to the right, in which case the centrifugal force is outside (in this case on the left)
As a result, a large force acts on the vehicle in that direction, and as a result, the left side of the vehicle sinks and the right side rises, and running stability is greatly impaired. Conventional vehicles are not equipped with devices that address such phenomena and increase running stability.
The improvement was required. Further, even when traveling while traveling up and down a hill, the vehicle may be tilted back and forth, which also reduces traveling stability. Apart from that, there is a problem of the hydroplaning phenomenon in running at the time of driving, and there has been no definitive method to deal with this problem in the past. In particular, when this problem and the above-described problem of turning left and right or climbing and descending a hill are intertwined, there is a possibility that running stability is greatly impaired.

The present invention has been made on the basis of the above points, and has as its object the running stability of a vehicle;
For example, a vehicle balance control device that can improve running stability when traveling while turning a curve left or right or traveling up and down a hill, and can suppress occurrence of a hydroplaning phenomenon. Is to provide.

[0005]

In order to achieve the above object, a vehicle balance control device according to the present invention has a balance weight disposed between a front wheel and a rear wheel of a vehicle and below a position of a center of gravity. It is a feature. In this case, it is conceivable to dispose a pair of side balance weights at least at one of a front portion, a center portion, and a rear portion between a front wheel and a rear wheel of the vehicle. Also, the front part between the front and rear wheels of the vehicle,
It is conceivable to arrange a central balance weight at at least one of the center and the rear. It is also conceivable to attach a pair of balance weights to both ends of the horizontal support member. It is also conceivable to independently attach a pair of balance weights. It is also conceivable to attach the side balance weight so as to be able to enter and exit a side balance room provided in the vehicle.

[0006]

That is, the vehicle balance control device according to the present invention arranges the balance weight between the front wheel and the rear wheel of the vehicle and below the position of the center of gravity, so that, for example, when the vehicle runs while turning left and right. Another object of the present invention is to improve running stability when traveling while traveling up and down a hill, and to suppress occurrence of a hydroplaning phenomenon. As a specific configuration, for example, a configuration in which a pair of side balance weights is disposed at at least one of a front portion, a center portion, and a rear portion between a front wheel and a rear wheel of a vehicle;
A configuration in which a central balance weight is disposed at at least one of a front portion, a center portion, and a rear portion between a front wheel and a rear wheel of a vehicle, or a combination thereof is conceivable.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to FIGS.
A first embodiment of the present invention will be described. First, as shown in FIG. 1, there is a vehicle 1 (indicated by a virtual line in the figure),
An engine (not shown) is mounted on a front portion of the vehicle 1. Further, a pair of front wheels 5, 5 are arranged at the front of the vehicle, and a pair of rear wheels 7, 7 are arranged at the rear. And, based on the driving force from the engine,
It is configured to drive and run by two-wheel drive of FR system or FF system or by four-wheel drive. In addition, a mechanism necessary for driving, a mechanism necessary for steering, and the like are not illustrated.

[0008] Balance control devices 9, 9 are provided between the front wheels 5, 5 and the rear wheels 7, 7 of the vehicle having the above configuration. Hereinafter, the configuration of the balance control device 9 will be described. One of the balance control devices 9, 9 is located between the front wheels 5, 5 and the rear wheels 7, 7 of the vehicle, and is disposed on the front side, and the other is disposed on the rear side. The balance control devices 9 on either side have the same configuration. First, as shown in FIG. 2, there is a horizontal support member 11, and this horizontal support member 11 has a horizontal portion 11a and inclined portions 11b, 11b.
It is composed of Vertical members 13, 13 are attached to the ends of the inclined portions 11b, 11b.
5 and 15 are respectively attached.

The side balance weight 15 is shown in FIG.
As shown in FIG. 4 and FIG. 4, it has a substantially disk shape and a through hole 15a is formed at the center position. Also, the through hole 15a
The upper part is cut out from both sides, the notch 15b,
15c. This shape is used to position the position of the center of gravity below.

Next, a central balance weight 17 is disposed between the pair of side balance weights 15 and 15 and at a central position. As shown in FIGS. 5 and 6, the central balance weight 17 is
The bolts and nuts tie-up tool 19
Fixed. Also, this central balance weight 17
However, in order to position its own center of gravity below, it is shaped so that its width increases as it goes down. As described above, between the front wheels 5 and 5 and the rear wheels 7 and 7 of the vehicle, a balance control device 9 disposed on the front side and a balance control device 9 disposed on the rear side. Has a similar configuration.

The operation will be described based on the above configuration. Normally, when traveling straight on a horizontal road, there is no problem. For example, if the vehicle tries to travel while turning to the left, as shown in FIG.
That is, the outside of the curve (the left side in the figure) sinks,
That is, a force acts such that the inside of the curve (the right side in the figure) floats. 7 and 8 show the vehicle 1 as viewed from the front in the traveling direction. At this time, the horizontal support member 11 and the pair of side balance weights 15 and 15 also make a similar movement and are inclined. At that time, the moment by the side balance weight 15 arranged on the right side in FIG. 7 becomes larger than the moment by the side balance weight 15 arranged on the left side in FIG. That is, when the center of gravity of the apparent in a tilted state and G _3, the center of gravity position G ₃ and a pair of side balance weight 15,1
The relationship of L ₂ > L ₁ is established between the distances L ₁ and L ₂ up to 5 and a pair of side balance weights 15 and 1
5 is W, the moment (W.times.W) by the side balance weight 15 disposed on the right side in FIG.
L ₂ ) is larger than the moment (W × L ₁ ) by the side balance weight 15 arranged on the left side in FIG. As a result, an effect of correcting the inclination of the vehicle occurs. By such an action, running stability when trying to run while turning to the left is improved.

The same can be said for the center balance weight 17. That is, when the vehicle is tilted, the central balance weight 17 is also tilted left and right, and an effect of returning the center balance weight 17 to the original state occurs. This also improves running stability when trying to run while turning to the left. or,
A similar action occurs in the front and rear balance controllers 9,9.

On the other hand, as shown in FIG. 8, when the vehicle runs while turning to the right, the reverse is true.
The moment (W × L ₁ ) due to the side balance weight 15 disposed on the left side in FIG. 8 is the moment (W × L) due to the side balance weight 15 disposed on the right side in FIG.
₂ ) larger than. As a result, an effect of correcting the inclination of the vehicle occurs. By such an action, running stability when trying to run while turning to the left is improved.

[0014] It also functions effectively against the hydroplaning phenomenon in rainy weather. First, since the weight is large, the occurrence of the hydroplaning phenomenon can be suppressed. In particular, when the vehicle travels while turning left and right, as described above, it is possible to effectively prevent the wheels located on the inside of the curve from floating, thereby suppressing the occurrence of the hydroplaning phenomenon in such a state. You can do it. Further, in this embodiment, since the balance control devices 9 and 9 are disposed between the front wheels 5 and 5 and the rear wheels 7 and 7 of the vehicle 1, respectively, the left and right directions described above are also applied to the longitudinal direction of the vehicle. As in the case of the direction, the function of maintaining the balance is exhibited. That is, when climbing or descending a hill, a case where the front or the rear of the vehicle 1 floats may be considered.
The balance control devices 9, 9 function on the front part and the rear part, respectively, and a moment for returning them acts, thereby improving running stability. The balance in the left-right direction and the balance in the front-rear direction are achieved, so that the front wheels 5, 5 and the rear wheels 7, 7 can all be in close contact with the road surface, whereby the load acts appropriately. Thus, the occurrence of the "hydroplaning phenomenon" can be suppressed. The side balance weight 15 and the center balance weight 17 are formed so that their centers of gravity are located below, so that they are more effective.

Next, a second embodiment of the present invention will be described with reference to FIGS. In this case, the outer periphery of the side balance weight 15 is covered with a cushioning member 31 such as rubber. Thereby, the impact in the event of an emergency can be reduced.
