Having a rail vehicle car versus VIN bolster and a pair of side frames, wherein the bolster is mounted transverse to the side frame. The shaft end and the side frame swing motion difference representative manner by the mounting interface between the base and allows the side swinging action of the side frame. Side swing action is johip and longitudinal self-steering ability. Self-steering ability can be obtained by utilizing a rocker oriented in the longitudinal direction to allow the resistance to deflection of the scaffolding to support the weight across the interface. Has an auxiliary centering element attached to the difference versus the base sheet element is made of a resilient elastomeric material. Furthermore, the truck is stick-has a friction damper for preventing the slip. The friction damper, the brake lining, or a similar part is provided on the side frame column surface for mating with the inclined surface or surfaces, or both. Friction dampers are operated to generate a uniform upward and downward frictional force as a whole. Friction damper may be mounted to the four corners at each end of the chassis bolster. Spring group may include a subgroup of springs of different heights.
