Patent ID: 7073636

Claim:
A disk brake with mechanical self-boosting for use in motor vehicles, comprising a brake bracket, a floating caliper, a caliper guide which guides the caliper transversely displaceably on the brake bracket, an actuating unit with which a friction brake lining can be pressed against a brake disk, and having a self-boosting mechanism which increases a contact-pressure force of the friction brake lining against the brake disk, the self-boosting mechanism ( 40 , 46 ) comprises a ramp mechanism having one brace ( 52 ) in a circumferential direction to the brake disk ( 16 ) on the brake bracket ( 12 ) and another brace ( 28 ) transversely to the brake disk ( 16 ) on the caliper ( 22 ), whereby, when the disk brake is actuated, a frictional or braking force exerted in the circumferential direction to the brake disc on the friction brake lining by the rotating brake disk is transmitted to the brake bracket and is not transmitted to the caliper guide.
