Abstract

1449249 Railway vehicle undercarriages SOUTH AFRICAN INVENTIONS DEVELOPMENT CORP 12 Nov 1973 [10 Nov 1972 (2) 9 Oct 1973 (2)] 52433/73 Heading B7L A railway truck 10 has two wheel sets 13, or more, each comprising a pair of wheels 12 rigidly mounted on a common axle 14 and mounted so as to be capable of yawing and lateral movement relative to a pair of side frames 16 mounting a bolster 18 wherein, any yaw constraint relative to the truck is so low as to allow reasonable rolling motion of the wheels 12 during curving, the wheel treads are profiled to have an effective conicity greater than 1 : 20, damping means 30 (only one of several being shown) are provided to suppress lateral and yaw oscillations and wherein the wheel sets are restrained longitudinally by anchor means 38 between the wheel sets 13 and the bolster 18 whilst yawing and lateral movements of the wheel sets are permitted by ball joints 42. The side frames 16 are mounted on horizontal rubber-metal sandwich springs 24 which in turn are mounted on horizontal flanges 28 of axle box adaptors 26. Each adaptor is connected by a longitudinal damper 30 and an external damper (not shown) to the side frames or alternatively the longitudinal and lateral dampers can be replaced by a single damper provided angularly. The anchors 38 are provided in the central longitudinal vertical plane of the truck and can comprise anchor tubular members connected to the bolster and each axle through rubber "0" rings as described with reference to Figs. 4 and 5 (not shown). The ends of the axles may be resiliently connected diagonally by damped wishbones or anchors, as described with reference to Figs. 6 to 11 (not shown). The invention may be applied to a four wheel wagon using diagonal anchors as described with reference to Figs. 13 and 14 (not shown). Alternatively the axles may be connected to generally horizontal W-shaped members whose apices are pivotally connected centrally of the truck as described in Figs. 15 and 16 (not shown). The trucks may have three axle sets connected by diagonal couplings as described with reference to Figs. 18 and 19 (not shown). In further embodiments, Figs. 20-22 (not shown), the invention provides for negative yaw constraint.
