Definitions

  • This invention relates to bogie suspensions for vehicles.
  • FIG. 1 is a side view of a four-wheel bogie according to the invention showing portions in section;
  • FIG. 2 is a vertical part section on section line II-Il of FIG. 1;
  • FIG. 3 is a plan view of half a cross-member
  • FIG. 4 is a section on section line lV-lV of FIG. 3.
  • FIG. I and in part FIG. 2, show one side of a four wheel bogie suspension for a lorry.
  • Bragie bracket 11 is shown (of a pair of such brackets) mounted on the outer face of a side member 40'of a lorry chassis.
  • the inner face of the side members carrying the brackets, and so the brackets themselves, are spaced apart by way of a cross-member 25 fabricated from pressings and described hereafter in connection with FIGS. 3 and 4.
  • the lower parts of the brackets are spaced by a welded cross member 26, which is triangulated up to the main cross member centre line.
  • the bogie brackets are made up of two pressings 11a, 11b (FIG. 2) bolted together. For reasons of clarity of description, FIG. 1 shows only the rear pressing 11a.
  • axles l2, 13 are carried at their outer ends in bearings mounted in carriers 14, 15 respectively.
  • each carrier is pivotably attached to spring eyes at the extremities of leaf spring 16 made up of three tapered leaves 16a, b, c. If preferred a plurality of untapered levels may be used.
  • the leaf spring 16 is clamped at its centre to a trunnion 17 which is pivoted on a rubber bush l8 bonded on a centre tube 19.
  • the centre tube 19 is bolted between the two parts 11a, b bybolt 20.
  • the opposite ends of the carriers l4, to those attached to the leaf spring 16 are attached by spherical rubber bushes 23 to one end of respectively radius arms 21, 22.
  • the other ends of the radius arms 21, 22 are attached to the bogie bracket 11 also by way of spherical rubber bushes 24.
  • FIGS. 3and 4 show welded pressings made up to form the cross-member 25 spacing apart the upper end of the bogie bracket 11 from the other bracket of the pair on the opposite side of the lorry chassis.
  • the cross-member 25 is of symmetrical form about the longitudinal centreline 30, only half the cross-member is shown in FIG. 3.
  • the cross-member is made up of two pressings 31, 32 which are welded together. Stiffening strips 33 are spot welded in the corners of both pressings.
  • Four drain holes 34 (only three being shown) are provided in the lower pressings 32.
  • the two lateral edges (only one edge 35 being shown) of the crossmember are bolted to the bogie brackets through the vehicle chassis side member 40.
  • the configuration of the bogie suspension is such that the braking and driving torques are fed back into the chassis by the spring 16 and radius arms 21, 22 without causing weight to be transferred between the axles in the designed laden condition. Weight transfer due to braking and driving torques in other than design laden conditions are insignificant.
  • axles can be displaced in the vertical plane relative to each other
  • cross-articulation diagonally opposite wheels can roll over the bumps at the same time, causing each axle to roll about its centre line, when seen in rear elevation.
  • the spring is twisted between its centreline and the rolled eye, and the radius rods twist on their spherical bearings.
  • a twimaxle bogie suspension for a highway vehicle which comprises:
  • a pair of bogie brackets adapted for mounting, with one bracket on each side of a vehicle chassis, on a common axis perpendicular to the fore-and-aft axis of the vehicle;
  • each axle being disposed parallel to the common axis, with one axle in front and one behind the pair of brackets, adjacent ends of the pair of axles each having a common bogie bracket;
  • axle carriers c. four axle carriers, one carrier being mounted at or near the end of each axle;
  • each carrier at adjacent ends of the pair of axles having a rigid radius arm pivotally linking the bottom end of the carrier to the common bracket, the pivotal connections on each end of each radius arm allowing relative vertical movement of the carrier with respect to the bracket and also allowing twisting movement of the carrier with respect to the bracket;
  • each carrier being pivotally linked, about a single axis parallel to said common axis, to one end of a common leaf spring which itself is pivotally linked at its center to the said common bracket;
  • a twin-axle bogie suspension as claimed in claim and said carriers respectively including a resilient 5 l in which the first cross-member is of cross-section bush which allows the radius rods to twist relatively providing the highest section moduli at the outer ends to the carriers and to the bracket. of the cross-member in the region of the bogie brackh. rubbing plates interposed between the bogie ets.
  • a twin-axle bogie suspension as claimed in claim bogie bracket so that slewing loads which occur at 1 in which the two bogie brackets are. also interconcornering are resisted initially by the resistance of nected by a second cross-member which is parallel to the said resilient bushes, deformation of which alsaid first cross-member and is located below the latter. lows the springs to move into contact with the said
