Self steering railway car |
摘要 |
A railway car includes a chassis supported on two sub-frames which are relatively pivotally movable. The sub-frames support propulsion motors, differentials, and driven flanged wheels. And intermediate steering axle and wheel assembly are transversly movable in response to track curvature and a steering beam extending outwardly from the steering axle pivots the sub-frames for steering movement.
