Multiple rotor disc brake

摘要

The multiple rotor disc brake has a primary rotor fixed to the wheel and a secondary rotor mounted to slide axially on a support also fixed to the wheel. The secondary disc is guided for sliding w.r.t. the first by projections (14) on one engaging aperture (15) in the other. The projections and apertures are crescent-shaped. - The projections are formed in a single piece with the disc (2) which carries them and are in contact with the apertures of the other disc only along their radially outer faces. There is a degree of radial and circumferential play between the projective and apertures.
