Patent ID: 6957723

Claim:
In a friction brake with self-boosting, the friction brake comprising a friction brake lining which can be pressed for braking against a brake body to be braked, an abutment for the friction brake lining on which the friction brake lining is braced at a bracing angle α, which effects the self-boosting, obliquely to a normal of the brake body, and an actuating device with which the friction brake lining can be pressed against the brake body for braking, and the actuating device having two toothing sets, meshing with one another, one of which is drivable and the other of which is operatively connected to the friction brake lining and acts on the friction brake lining at a force introduction angle that is oblique to a normal of the brake body, the improvement wherein the toothing sets ( 30 , 32 ) meshing with one another have an engagement angle α e which produces a force introduction angle β, at which the toothing sets exert an actuating force on the friction brake lining, of approximately 90° minus the bracing angle α.
