摘要:
A railcar suspension assembly at each end of a railcar eliminates the use of a car body bolster and allows payload forces to be carried at railcar side sills into a cross-extending box-like section. The section has bearing wear plates attached to it directly over the truck sideframes so that the forces pass directly downward, into the bearing assembly which is attached to the bolster ends. The forces then are transferred into a conventional sideframe. The loading path allows the bolster to be made with a lightweight midsection and conventional ends having friction shoe pockets.
