Abstract:
1. In a disk brake with self-boosting, having a friction brake lining and having an actuation unit with which the friction brake lining can be pressed against a brake disk, and having a self-boosting device which when the disk brake is actuated converts a frictional force, exerted by the brake disk against the friction brake lining pressed against the brake disk, into a contact-pressure force which in addition to the actuation unit presses the friction brake lining against the brake disk, and the self-boosting device has a bracing means, on which the friction brake lining is braced obliquely to the brake disk at a support angle upon braking and opposite which bracing means the friction brake lining moves in the direction of the brake disk when the friction brake lining is moved for braking in the direction of the brake disk, the improvement wherein the friction brake lining ( 16 ) comprises a return-travel limiter ( 48 ), which limits a travel by which the friction brake lining ( 16 ) is lified from the brake disk ( 18 ) upon release of the disk brake ( 10 ); wherein the bracing means ( 32 ) is movable in the direction of the brake disk ( 18 ) and comprises a return-travel block ( 52 , 54 ), which prevents a motion of the bracing means ( 32 ) away from the brake disk ( 18 ); and wherein the bracing means ( 32 ) comprises a spring element ( 40 ), which urges the bracing means ( 32 ) in the direction of the brake disk ( 18 ).
