<p>A truck for the pivotal support of two car bodies, particularly of articulated rail motor cars, comprises a truck frame having a vertical pivot for each car mounted in spaced longitudinal locations on the truck frame. A transversely extending swiveling bolster is centrally mounted for pivoting movement on each vertical pivot and each bolster includes a spring support adjacent each respective end for resiliently supporting the associated car body. The truck also carries slide means, such as interengaged slide plates on the truck and the bolster underlying the spring supports for slidably supporting the respective ends of the bolster on the truck.</p> |
