Friction ring with securing elements for a track wheel

Abstract

In order to provide a track wheel, in particular a friction ring for a track wheel, which allows for effective cooling of a braking device of the track wheel, a friction ring (100) for a track wheel of a rail vehicle is proposed, comprising a friction side with a friction surface and a rear side (10) facing away from the friction side, wherein securing elements (11) are arranged on the rear side (10) protruding from the rear side (10), wherein the securing elements (11) have a substantially triangular shape when viewed from above, wherein it is provided that each of the securing elements (11) comprises a radial length R, wherein the friction ring (100) comprises an inner diameter Ri and an outer diameter Ra, and wherein R=0.30-0.90 (Ra-Ri).

Dependencies are inferred from the claim text.
