Abstract
A self-steering wheel truck for use with a railway locomotive or powered transit car in which tractive force is transferred from the axles to the frame through traction rods and steering beams connecting with the end axles. The steering beams are interconnected through upstanding shafts pivotally connected to transverse frame members, control arms and resilient curved diagonal alignment arms. The resilient curved alignment arms move the end axles to equal and opposite angulation under compression for a return to parallel operation upon release of self-steering forces.
