Definitions

  • This invention relates to railway wagon suspension units; such units may be used separately in conjunction with each wheel of a single axle two-wheel assembly, i.e. a pedestal, or embodied in side frames in a composite bogie structure, e.g. a four-wheel two axle or six-wheel three axle bogie.
  • a railway wagon suspension unit comprising a frame mounted over a saddle accommodating an axle-journal housing, with a load spring suspension system disposed between the frame and the saddle, the saddle bearing on the housing through a mounting adaptor including a curvilinear surface engaging a further surface whereby to permit pivotal lateral motion of the saddle and the housing relative to one another.
  • a unit is the subject of GB-A-1 433948.
  • the present invention mitigates this drawback by providing in the mounting firstly a body of elastomeric material. With this arrangement there is permitted a controlled degree of movement particularly in respect of the longitudinal motion of the kind referred to where the elastomer now yields to shear stress. Whereas this principle has been adopted in certain cases hitherto, namely, as disclosed in GB-A-1025808 and GB-A-1 532441 and US-A-3638582, in this invention lateral pivotal movement of the kind by which the saddle pivots or swings about the housing mounting adaptor is accommodated whilst direct lateral translational movement of the saddle relative to the adaptor is restrained.
  • a railway wagon pedestal unit comprising a frame 1 mounted over a saddle 2 accommodating an axle-journal housing 3.
  • the saddle embodies a platform having a fore-section 4 and an aft section 5.
  • Mounted on these sections are spring nests 6, 7 respectively engaging friction wedges, only one pair of which 8, 9 is visible.
  • the wedge 8 bears on a friction pad 10 on the side of the saddle and a pad 11 on the inclined under-surface of the wedge 9, which wedge itself nestles in a right angled recess 12 formed in the frame 1.
  • the spring nests comprise a combination of springs having different rates which together effect three stage springing.
  • the journal housing accommodates a wheel axle 13 in roller bearings 14.
  • an 'adaptor' 15 comprising a cast member 16 having a recess in its upper surface accommodating an elastomeric body, more particularly a rubber block 17, which is bonded to an upper plate 18 carrying an elongated rib 19.
  • the rib 19 has a curved surface on which bears an inversely curved elongated channel member 20 which is mounted on the underside of the saddle aperture.
  • Two studs 21, 22 extend from the top of the saddle casting into slots, only one of which (23) is visible, in the pedestal frame 1. This ensures retention of the saddle within the pedestal unit should the latter be lifted.
  • a curved clip member 24 is located on the bottom of the saddle aperture to prevent the journal housing from becoming detached from this aperture and a pair of 'stop' blocks 25 are welded to the sides of the saddle to limit relative longitudinal motion between the journal housing adaptor and the saddle.
  • the rubber block 17 is shearing longitudinally up to and during the stage at which the wedges start to move, limited only by the casting 16 abutting the stop block 25.
  • FIGS 3 and 4 Alternative forms of mounting are shown in Figures 3 and 4, both designed to eliminate lateral clearance.
  • the rubber block (26) is bounded to upper and lower plates 27, 28, the upper plate 27 additionally being spigotted at 29 to the elongated metal rib 19, the whole defining a 'flared' U-shaped configuration.
  • Figure 4 the design is similar but the lower plate is actually made up of three separate elements including two side plates of which only 28A is visible. The intermediate plate within the rubber mounting is omitted.
  • the pedestal unit described may be manufactured as shown complete with the rocker assembly or the latter may be separately incorporated in 'converted' units, i.e. existing units which have been machined to accommodate the rocker assembly conversion.
