Definitions

  • the lift and the guidance are produced by a single-stage suspension with guidance of the bearing box for each end of the axle.
  • This assembly therefore does not have a transverse suspension and, therefore, there is not only a level of frequency filtration between the axle and the body of the vehicle which causes very often sudden lateral movements therefore generating shocks.
  • the present invention relates to a device which applies to a rail vehicle comprising only two axles but which uses a primary suspension, a secondary suspension and a transverse suspension. So we can therefore, while maintaining the simplicity of mounting a two-axle vehicle, find the comfort of a rail vehicle mounted on bogies.
  • the device consists of two suspension stages, one connected directly to the bearing box by means of a lower longitudinal part on an intermediate spar which is supported by the other, the suspension secondary, bearing on prismatic boxes forming a stop, so as to give a slight inclination from bottom to top and in opposition to the members constituting the secondary suspension, moreover these boxes are connected directly to the chassis of the vehicle then the aforementioned intermediate beams are connected two by two by cross members arranged symmetrically with respect to the axis of the axle and thus forming a frame maintaining the geometry of the assembly and supporting the braking device.
  • the primary suspension rests directly on the rolling box by one of its ends and on prismatic boxes and inclined by its other end, these boxes being integral with an intermediate spar holding the part lower of the elements forming the vertical secondary suspension which is fixed by its upper end to the chassis of the vehicle, cross-members arranged symmetrically with respect to the axis of the axle forming a frame with the intermediate beams to ensure the correct geometry and holding the assembly and maintaining the braking device then, to ensure the drive of this construction, there are provided on one side thereof longitudinal control rods articulated on elastic ball joints integral with one of the intermediate beams and others from the vehicle chassis.
  • Fig. 1 is an elevation of a first embodiment of the two-stage suspension device for an axle of rail vehicles.
  • Fig. 2 is a plane corresponding to FIG. 1.
  • Fig. 3 is a sectional elevation substantially along line III-III of FIG. 4 of a second embodiment of the two-stage suspension for an axle of rail vehicles.
  • Fig. 4 is a plane corresponding to FIG. 3.
  • Fig. 5 is a side elevation of a suspension device for a two-wheeled axle for wagons according to the invention.
  • Fig. 6 is a top plan corresponding to FIG. 5.
  • Fig. 7 is a section substantially along the line VII-VII of FIG. 6.
  • a line 1 the chassis of a rail vehicle for example of a passenger car.
  • This chassis usually consists of two suitably braced beams.
  • the lower part of the side members of the chassis 1 carries at each of their ends boxes 2, 3 of prismatic shape whose front faces 2a, 3a are flat to form a stop intended to receive the end 4a of a cylinder 4 which are composite elements layered in sandwich rubber metal .
  • the above description shows that the geometry of the assembly is produced using the intermediate beams 6 and the crosspieces 7, 8 which form a rigid frame ensuring the geometry of the wheel set S12 considered and correct drive of the assembly .
  • the first suspension stage constituted by the suspension elements 15 absorbs a large number of vertical frequencies while the cylinders 4 absorb the longitudinal and transverse frequencies thus avoiding sudden lateral movements generating shocks.
  • the cross member 8 carries the braking device 20, the shoes 21 of which are seen near the tire of the wheels 12, 13.
  • This assembly is simple, compact and makes it possible to provide vehicles on rails and in particular passenger cars with comfort identical to the comfort obtained when using bogies each comprising two axles with two wheels. But the latter solution is much more expensive both in the production and in the maintenance of the equipment. In addition, the use of bogie vehicles very often causes an increase in energy expenditure.
  • axle described above can receive a drive axle for a vehicle of the light railcar type.
  • the engine reaction box is then secured to the body by means of elastic joints not shown.
  • the spacing of the cylinders 4 forming the secondary suspension is provided sufficient to ensure an anti-rearing torque to the frame composed of the intermediate beams 6 and of the cross members 7 and 8.
  • FIG. 3 shows an alternative embodiment of the two-stage suspension device in which the vehicle chassis is represented by the line 30, this chassis carrying at specific points two plates 31 on which rest the upper ends laughing springs 32 embedded in an elastic material 33 for example rubber.
  • the lower part of these mixed elastic elements 32, 33 rests on plates 34, 35 extending each intermediate spar 36 connected to the other symmetrical spar 36 by cross-members 37, 38 with round section arranged symmetrically with respect to the axis 39 of the axle 40 carrying the wheels 41,42.
  • Each intermediate beam 36 substantially takes the form of an inverted “U” which substantially covers the end parts of each axle 40 so that each bearing box 43 is disposed just below the transverse lower part 36a of each intermediate beam 36 in "U” overturned.
  • the branches 36b, 36c of the crosspiece 36 in an inverted “U” shape carry in their median zones, inner sides, boxes 138 on which bear elastic blocks 39 in chevrons of a type known per se, these elastic blocks resting on their other ends on the outer carcass 47 of the bearing box 43 receiving the end of the axle 40 considered.
  • the outer carcass 47 carries a flat 50 intended to cooperate with a stop 51 placed just above on the horizontal lower part of the intermediate spar 36 in an inverted "U” considered.
  • the drive of the axle is necessarily carried out in an artificial manner by two control rods 55 articulated at 56 on the end 36d of each intermediate spar 36 and on a base 57 secured to the underside of the chassis 30 of the vehicle.
  • the articulations of the connecting rods 55 are constituted by elastic ball joints 60, 61.
  • one of the crosspieces 38 carries the braking connecting rods 65 controlling the rotation of the brake pads 66 rubbing against the outer periphery of each of the wheels 41, 42.
  • the retaining frame constituted by the intermediate beams 36 and the crosspieces 37, 38 ensures the correct geometry and the strength of the assembly.
  • the secondary suspension can receive vertical and transverse hydraulic shock absorbers of a common type.
  • the vertical dampers placed at the right of each secondary suspension element are such that they can also dampen any galloping movements of the frame 36, 37, 38.
  • a line 100 the chassis of a rail vehicle, for example a passenger car.
  • This chassis normally consists of two beams suitably braced.
  • the lower part of the frame rails 1 carries at each of the ends of the boxes 102, 103 whose front face 102a, 103a is inclined substantially at 45 ° relative to the longitudinal axis X1, X2 of the car (see fig. 6) .
  • the aforementioned inclined faces 102a, 103a each carry a simple elastic element 104 of the same family as the bolsters, that is to say composite elements each consisting of at least one spring element, made of flexible deformable material, for example rubber treaty.
  • the four elements 106 form the vertical and transverse secondary suspension in a frame 107 consisting of intermediate beams 108 and cross members 109.
  • each axle 111 on which the wheels 112, 113 are mounted are supported by lower parts 114 of appropriate shape and which are connected to the intermediate beams 108 by suspension elements 115- 116 arranged vertically and which are fixed by their upper parts on supports 117-118 integral with the lower part of the intermediate beams 108.
  • each inclined face 102a, 103a of the boxes 102, 103 is disposed inclined on the vertical in a similar manner to the suspension members 106 and also inclined transversely so that the normal to the plane which it represents contributes to the fictitious center of rotation of the axle 111 thus formed.
  • each simple elastic element simulates a conical pivot portion of large diameter and the work of these elements is similar to that of an elastic pivot.
  • This device therefore generates the desired freedom of rotation and has the advantage of being able to allow, by dimensioning and choice of rubber, the precise determination of the elastic rotation torque.
  • the intermediate fixing element 102a, 104 allows the use, in this assembly, of separate elements so that the parts are easily interchangeable.
  • Another way to mount this element is to place it between the secondary suspension bolster 106 and the movable frame.
  • the first solution is preferred because it better places the sandwich sandwich elements 102a-104.
