Definitions

  • the object of this invention is to provide good stabilization of a vehicle at high speeds, while permitting the vehicle to move freely through curves, even of small radius.
  • the two axle bearings of one wheel-set are each elastically interconnected with both axle bearings of the other wheel-set to provide bracing therebetween, and the vehicle body is supported on the wheel-sets in a manner offering substantially no restraint to relative horizontal rotation between the vehicle body and the wheel-sets.
  • the invention provides diagonal bracing and longitudinal bracing between each axle bearing of a wheel set and the two axle bearings of the other wheel-set.
  • the elastic interconnections between the axle bearings may comprise a system of links, springs, rods or other members capable of providing the required amount of elasticity, or conversely stiffness, in compression and tension.
  • the elastic interconnections may consist of metal rods with rubber bushes of appropriate stiffness at their ends, or alternatively rubber members may be interposed along the length of the rods to provide the required elasticity.
  • the elastic interconnections may comprise a fluid system.
  • FIG. I shows a plan view of a first construction of truck
  • FIG. 2 shows to a larger scale than FIG. I the connection of one of the elastic bracing members of the bogie to an axle bearing housing;

  • the manner in which the vehicle body is supported on the truck is however different from that of FIG. I.
  • the axles of the wheel-sets 1 and 2 are encased in axle housings 29 and 30 which are connected at their ends to the bearing housings, to provide rigid structures with the bearings housings.
  • a beam 31 extends along the central longitudinal axis of the truck and is mounted at its ends on vertical pivots 32 and 33 to tie the wheel-sets I and 2 together but permit free horizontal rotation of the sheel-sets relatively to the beam 31.
  • the vehicle body is mounted on the truck through vertical springing 34, which, it will be appreciated by those skilled in the art, will not restrain to any significant extent the horizontal rotation of the vehicle body relatively to the wheel-sets.
  • the beam 31 could be omitted in the case where the elastic bracing members 9 to 12 are mechanical struts such as those shown in FIGS. 1 and 2.
  • the vertical springing supporting the vehicle body 27 could be mounted on the beam 31, so that no restraint to horizontal rotation of the vehicle body relatively to the wheel-sets is provided.
  • Suitable lateral stability of the vehicle body will be provided by springs or tie rods as will be appreciated by those skilled in the art, but in a manner providing no significant restraint to the horizontal rotation of the vehicle body relatively to the wheel-sets.
  • FIG. 6 is shown the manner in which the truck of FIGS. 4 and supports the adjacent ends of two vehicle bodies 35 and 36 articulated together at 37.

  • the pistons 44 of the fluid displacers are connected to the axle bearings 5 and 8 by universal couplings and the cylinders 45 are fixed in space for example by being secured to the vehicle body (not shown) or a frame connected between the axles or to a beam connected between the axles such as the beam 31 of the FIG. 4 and 5 constructions.
  • the truck shown in FIG. 7 may be provided with side frames, vertical springing and a bolster in the manner of FIG. 1 for mounting the vehicle body.
  • the fluid displacers have been shown in FIG. 7 as pistons and cylinders, other types of actuators may be used, for example rolling diaphragm type actuators.
  • the fluid displacers or other actuators used can be operated in response to an external signal so as to steer the vehicles in curves.
  • the signal would be such as to deform the truck in plan view by extending or contracting the appropriate elastic members so that the axles extend radially to the curve.
  • FIG. 8 is shown a form of elastic member designated 47 corresponding to that shown in FIG. 2 but in which a viscous or hydraulic vibration damper 48 is interposed between the rubber washers 49 and 50 to provide an appropriate damping force.
  • FIGS. 9 and 10 an arrangement whose manner of operation corresponds essentially to that of the previously described arrangements, but in which the required elasticity is provided by a torque tube 51.
