摘要： A railway truck has a unitary cast steel frame with a primary wheel-set-to-frame suspension formed by chevron shaped metal/elastomeric pads between the journals and the frame pedestals, a secondary frame-to-bolster suspension formed by rectangular elastomeric pads in rectangular configuration, and a tertiary suspension between the bolster and the car. The primary suspension units are mounted by L-shaped members permitting ready vertical adjustment. An anti-roll torsion bar is provided between the bolster and the car body despite the limited available space by disposing it inside the bolster. Closer clearances are possible between the truck components by providing a cam and cam follower between the car body and the truck frame, in this embodiment between the bolster and the truck frame, that limits the possible lateral displacement of the car body as the steering angle of the car body on the truck frame increases.
