Abstract
A swing link suspension of a four-wheeled rail vehicle has respective pivotal mountings for permitting relative lateral and longitudinal movements of the wheelsets and vehicle body. Those pivotal mountings permitting longitudinal movement are provided with separately formed linings of a material providing a controlled frictional restraint to the longitudinal movement. Longitudinally extending traction rods incorporating resilience in their lengths are connected between the wheelsets and the vehicle body to provide a resilient yaw restraint on the wheelsets.
