ABSTRACT:
This invention provides a railway wagon suspension unit comprising a frame mounted over a saddle accommodating an axle journal housing. The saddle can rock laterally relative to the journal housing. Suspension means are disposed between the frame and the saddle including load springs for vertical support, and a friction wedge block is mounted on the saddle and firmly biassed against the axle journal housing to provide substantially constant frictional forces against lateral motion between the saddle and the housing independently of vertical movement or loading of the frame. In this manner lateral restraints imposed on wheel set oscillations during service are not load sensitive as has been the case with some wedge-pot dampers and other suspensions hitherto.
