Abstract
An electromechanical disk brake with mechanical self-boosting for instance by a ramp mechanism, which is intended for use in motor vehicles in which the ramp mechanism is braced in a circumferential direction relative to a brake disk on a brake bracket, in order thereby to keep a caliper guide of a floating caliper free of frictional and braking forces of the disk brake.
Claims5
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.
