Abstract

A truck for a railroad car has front and rear wheelsets 12 and 14 with axle ends rotatively carried in U-shaped front and rear steering arms 32 and 42. The steering arms are supported in pedestal jaws of side frames 58 and 60 with resilient pads interfacing between the steering arms and the side frames. The resilient pads allow each wheelset and steering arm to rotate or yaw to an out-of-square condition with respect to the side frame as the railroad car proceeds, for example, around a curve in the track on which the car is travelling. This rotational movement is regulated by a joint 164 connecting the front and rear steering arms and located in a cavity 158 of a transverse bolster 161. <IMAGE>
