ABSTRACT:
The invention relates to an electromechanical, self-boosting friction brake, in particular a disk brake. The friction brake is embodied with a wedge element for exerting contact pressure on a friction brake lining; a wedge angle (α) is selected such that a brake parameter C* is located at or near a pole point. As a result, a high self-boosting that tends toward infinity and consequently a low actuating force are attained. To avoid blocking of the friction brake, an actuating device is embodied to block an independent motion of the wedge element, or has a regulating device for regulating a contact pressure of the friction brake lining against a brake body (brake disk).
