Definitions

  • This invention relates to a device in accordance with the introduction to the main claim.
  • the first known arrangement (used on railway trains, underground trains and trams) only limits this problem without properly solving it.
  • movable bogies to not achieve optimum reduction in the noise and vibration transmitted to passengers by the wheels when the vehicle or coach is travelling on a bend unless there is a considerable use of special soundproofing means and vibration absorption means interposed between the bogie and the coach body.
  • the second arrangement (single axle with means for its connection between adjacent vehicles) solves some of the problems connected with the use of bogies (such as the increase in the vehicle height), but gives rise to parasite movements of the axles due to the mutual displacement which normally occurs between vehicles along a curved path. This has consequences both for the vehicle running stability and for the comfort of vehicle passengers.
  • An object of the present invention is therefore to provide a device for orientating the support and guide means (comprising one or more axles associated with each other in a bogie, wheels, brake discs mounted on the wheels, suspension members, shock absorbers, braking members and usual brake pads) of a railway vehicle which overcomes the aforesaid drawbacks in an optimum manner during the movement of the vehicle along a curved track.
  • a particular object of the present invention is to provide a device by which track and wheel flange wear is drastically reduced on bends, with evident advantage in terms of maintenance costs.
  • a further object is to provide a device by which the noise and vibration is drastically reduced on bends, with evident advantage to the vehicle environmental impact and comfort on board.
  • a further object is to provide a device which can replace conventional railway bogies by guided axles if the load per axle of the vehicle allows it, with evident advantage to vehicle cost and weight.
  • a further object is to provide a device which enables the vehicle floor level to be reduced by virtue of the fact that wheels and suspensions housed under the seats undergo only small movement relative to the vehicle body, so leaving a sufficient corridor for passage.
  • FIG. 1 shows two coupled railway vehicles 1 and 2 during travel along a curved track 3.
  • Each vehicle 1 and 2 comprises in the example single axles 7 and 8 positioned in proximity to its opposing ends 9 and 10; each of these axles is guided by a device according to the invention to enable them to incline to the longitudinal axis of the vehicle when this travels along a curved track portion in order to enable the usual wheels to follow the tracks.
  • the device utilizes the relative rotation which occurs between the bodies 1A and 2A of the vehicles 1 and 2 when on the bend.
  • the device according to the invention comprises elements common to the vehicles 1 and 2 which will be indicated respectively by numerals followed by the letter A (vehicle 1) or B (vehicle 2).
  • A vehicle 1
  • B vehicle 2
  • FIG. 2 For simplicity of description that particular device of Figures 5-9 applied to the vehicle 2 is described, with only those parts common with the device of vehicle 1 being followed by a letter. Normal vehicle parts are merely numbered.
  • the axle 8 of the vehicle 2 supports usual wheels 14 at its ends 12 and 13.
  • Axle boxes 15 are present at these ends and cooperate with usual suspension springs 16; usual shock absorbers 17 and 18 of known operation are also present at these ends.
  • the axle 8 is associated with the device according to the invention comprising a rocker arm 20B pivoted on its centre line 21B and supported by fixed arms 22 and 23 forming part of the body 2A of the vehicle 2. These arms carry at their free end a C-shaped member 50 to which the middle of the rocker arm 20B is connected by a pin 60.
  • the ends 24B and 25B of the rocker arm are hinged at 26B to arms 27B hinged at 28B to slides 29B slidable along longitudinal guides (parallel to the vehicle axis F) 30B associated with the vehicle bodies 2A.
  • This member, the connecting rods and the slide define a guide parallelogram between this latter and the member 34B.
  • Each guide member supports corresponding shock absorbers 17 and 18 and a usual guide 35 for a brake 36 associated with the corresponding wheel 14. Said member enables relative movement of the corresponding axle box 15 to take place by way of usual bearings (not shown).
  • the axle box support members 34B also carry a bracket 37 arranged to cooperate with usual buffers 38 provided to the side of the wheels to receive the lateral stresses arising from forces transverse to the axis F of the vehicle 2 during the movement of this latter along the track 3.
  • Each spring 16 is associated with the vehicle body, which comprises an intermediate portion 55 located between the wheels 14 and depressed relative to lateral portions 56 to which the springs 16 are connected.
  • auxiliary springs 40B are provided between the vehicle body and the rocker arm 20B. These springs are preferably located in a position symmetrical about the C-shaped member 50 which supports the rocker arm.
  • a buffer element 41B for example an elastic or rubber body to absorb those stresses acting on the vehicle along the direction of its axis F (due for example to impact between two adjacent vehicles).
  • This buffer can act directly on the rocker arm 20B or not.
  • each slide 29A, B can be associated with a shock absorber 44 fixed to the body of the relative vehicle (as shown in Figures 2 and 3) to compensate and further damp any oscillations undergone by the slides during vehicle movement.
  • a member or shaft 70 connecting together the devices of the aforesaid type associated with the adjacent vehicles 1 and 2 is connected to the C-shaped member by the pin 60 and a ball joint 42.
  • the shaft 70 is hinged by the pin 60 to the rocker arms 20A and 20B of the two adjacent vehicles (see Figures 2-4).
  • a further connection shaft 71 is hinged to the rocker arms 20A and 20B (in known manner, for example in proximity to their ends 24A and 24B) of the two adjacent vehicles to form with said rocker arms and with the shaft 70 an articulated guide parallelogram system which, when in use, enables the axles 7 and 8 of the two vehicles 1 and 2 to orientate themselves and follow the curved track with their wheels 14.
  • the axis W of said axles inclines to the vehicle axis F so that said wheels follow the track 3 in the best manner.
  • a rear end vehicle has that axle 7 close to the (free) end 9 connected to the other axle 8 by a motion transmission and reversal system; this can be achieved for example by connecting close to the end 10 of the vehicle two pulleys 80 with which there cooperate crossed cables 81 connected to the ends 12 and 13 of the axle 7.
  • Other arrangements are however possible, such as those comprising connection rods and reversing linkages, flexible cables or usual hydrostatic transmissions.
  • axle 7 at the free end 9 can be advantageously connected by pairs of connecting rods 700 to slides 710, these latter connected by connecting rods to the rocker arm 720 hinged to the vehicle body at 730.
  • the rocker arms 20A and 20B are perpendicular to the longitudinal axis F of each vehicle and by means of the arms 27A and 27B maintain the lines Q joining the pairs of slides 29A and 29B perpendicular to the longitudinal axis F of each vehicle.
  • the guide parallelogram maintains the rocker arms 20A and 20B perpendicular to the longitudinal axis of the vehicle, and in the aforegoing manner the axle boxes remain in their correct position.
  • the device therefore does not give rise to parasite rotation of the axles 7 and 8, and any hunting motion of these latter (due to attainment of critical speeds) is opposed and absorbed by the shock absorbers 44.
  • the guide parallelogram (comprising the shafts 70 and 71 and the two rocker arms 20A and 20B) assumes relative to the two coupled vehicle bodies an intermediate position provided by the symmetry of the elastic return action of the suspension springs 16 for the guided axles 7, 8 and, if provided, of the auxiliary springs 40A, B. Consequently the line E perpendicular to the shaft 70 passing through its central point extends radially, ie passes through the centre of the bend, and the rocker arms of the guide parallelogram, by remaining parallel to this perpendicular line, assume a "nearly radial" position, with a slight excess rotation beyond the rigorously radial position.
  • the arms 27A, B positioned slightly inclined, transmit to the slides the component of the movement in the direction parallel to the vehicle longitudinal axis so as to position the pairs of slides 29A, B. These move along the respective guides 30A, B to each transmit their position, via the connecting rods 31A, B and 32A, B, to the corresponding pairs of axle boxes. Consequently the axles 7 and 8 rotate about the point of intersection of their axis W and the axis F of the vehicle to which it pertains, to undergo radial positioning with respect to the vehicle to which they pertain.
  • the rotation of the axles connected by the device of the invention is transmitted reversed to the free end axles (for example by the pulleys 80 and cables 81) so as to orientate them in the correct direction.
  • the described device enables:
  • a device applied to support and guide means of vehicles defined as single-axle has been described.
  • the described device In addition to single axles, the described device also enables railway bogies to be guided should it be necessary to use these. In such a case the advantages of the aforesaid points b) and c) are partially obtained.
  • the bogie can be directly connected to the arms 27A, B positioned parallel to the axis F of the corresponding vehicle.
  • the described device can also be associated with an axle which receives its movement from a usual motor mounted under the vehicle body.
  • the members 34A, B are structurally modified to receive the usual motion transmission elements, but must again be connected to the connecting rods 31A, B and 32A, B.
  • these latter can be positioned parallel to and on the same side of the relative axle box 15 (as in Figure 7) or can be positioned parallel to each other with one on one side and the other on the other side of the axle box.
