Abstract
A railway-vehicle truck has a support structure in the form of a horizontal rectangular plate the opposite ends of which carry respective transverse tubular supports. Each tubular support mounts a shaft the two ends of which carry respective arms. Each arm rotatably mounts a railway wheel. Between each shaft and its corresponding tubular support are provided bushes of elastomeric material which permit misalignment of the shaft and support as the vehicle traverses a bend. The horizontal plate of the support structure is formed with a rectangular aperture mounting a sliding block for sliding movement transversely of the truck, though limited play is also provided for longitudinally of the truck. A truck pivot pin extends vertically down from the vehicle body through a central hole in the sliding block. Upper and lower plate elements are carried by the pivot pin and serve to sandwich upper and lower annular elements of elastomeric material between themselves and the facing surfaces of the support structure.
