Abstract
A railway motor truck has a pair of wheeled axles, the wheels having profiled treads to effect self-steering and the axles resiliently supporting a truck frame with sufficient yaw freedom to accommodate wheel-induced steering movements, and an interconnection between the axles, comprising a transverse shaft journaled in the truck frame intermediate the axles, normally substantially vertical levers affixed to the end portions of the shaft, and a pair of links respectively connecting the opposite ends of one axle to the upper and lower ends of the respective levers, and a second pair of links respectively connecting the opposite ends of the other axle to the opposite ends of the respective levers. Axle-to-axle load transference is substantially prevented by traction connections between the truck and a supported vehicle body effecting traction transmission therebetween substantially at rail level, and pitching of the truck frame from motor torque reaction is minimized and vertical and yawing movements of the axles are facilitated by the provision of a quill drive and rigidly mounting the traction motors on the truck frame.
