ABSTRACT:
A brake disc for an axle of a railway vehicle comprises a friction disc annular element mounted concentrically on a hub by a plurality of clamping sleeves or bolts seated in radially opposed bores in the hub and annular element. A pretensioned resilient retaining member exerts a radially inwardly directed force against the radial outer end of each clamping sleeve or bolt. The retaining member is positioned against stop surfaces disposed radially outwardly of the outer end of the cylindrical or bolt element and formed on the ribs which interconnect a pair of axially spaced friction elements constituting the annular element or on the inner surfaces of the friction elements.
