Patent ID: 7143873

Claim:
A motor vehicle brake system, comprising: at least one first electromechanical wheel brake; and at least one second electromechanical wheel brake ( 10 ), each first and second electromechanical wheel brake comprising an electric actuator for generating an actuating force, and a self-boosting device for automatically boosting the actuating force generated by the actuator to thereby press a friction element against a rotatable component ( 14 ) of the wheel brake ( 10 ), wherein each self-boosting device comprises a wedge ( 18 ), which is supported against an associated abutment ( 22 ) and has at least one wedge face ( 20 , 20 ′) disposed at an angle of slope (α), the self-boosting device of the first wheel brake comprising at least one wedge face ( 20 ), which is used to boost the force in braking operations during forward travel, the self-boosting device of the second wheel brake comprising at least one wedge face ( 20 ′), which is used to boost the force in braking operations during reverse travel, and wherein the friction element of the first wheel brake, by utilizing the wedge face ( 20 ) used to boost the force in braking operations during forward travel, and the friction element of the second wheel brake, by utilizing the wedge face ( 20 ′) used to boost the force in braking operations during reverse travel, are clamped against the rotatable component of the wheel brake ( 10 ) to function as a parking brake.
