摘要： The invention relates to a motor vehicle brake, in particular an electromechanically actuable motor vehicle brake, having an actuator assembly (10) comprising: a housing (12), an actuating element (18), which is movable relative to the housing (12), for displacing a brake lining, a motor drive (22), a movement mechanism arranged between the motor drive (22) and the movable actuating element (18), and a gearbox arrangement (26) assigned to the movement mechanism, wherein the movement mechanism has a ball screw (28) with a spindle (76) which can be driven in rotation and with a nut (86) which is movable linearly in the housing (12), wherein in order to move the actuating element (18), the nut (86) can be moved within the housing (12) by virtue of the spindle (76) being driven in rotation. It is provided in said motor vehicle brake that the gearbox arrangement (26) has a wrap spring coupling (70) which is arranged in the power flow between the motor drive (22) and the spindle (76) in such a way that the wrap spring coupling (70) permits a transmission of torque from the motor drive (22) to the spindle (76) and is designed to block a transmission of torque from the spindle (76) to the motor drive (22).

摘要： The invention relates to a brake system (10; 110; 210; 310) for a motor vehicle comprising a master brake cylinder (16), inside of which a primary piston (18) for generating a brake pressure in a hydraulic braking circuit can be displaced according to an actuation of a brake pedal. The primary piston (18) can be displaced inside the master brake cylinder (16) under the effect of a hydraulic servo pressure circuit (12). This hydraulic servo pressure circuit (12) comprises a pressure source (50) for generating the servo pressure and a pressure accumulator (66) for maintaining a minimal servo pressure inside the servo pressure circuit (12). According to the inventive brake system (10), the pressure accumulator (66) of the servo pressure circuit (12) can be supplied with hydraulic fluid according to the servo pressure prevailing inside the servo pressure circuit (12). Alternatively, the invention relates to a brake system (410) without a pressure accumulator, rather the servo pressure circuit (410) has a bypass channel (478), which can be activated according to pressure and which is connected upstream from the master brake cylinder. According to the invention, the force input element (32) can be coupled to the primary piston (18) or uncoupled therefrom.

摘要： The invention relates to a pressure generator (10) for a vehicle brake system and to a method for mounting said pressure generator in a vehicle brake system (70). The pressure generator (10) is modular and is formed from a pump subassembly (12) and a receiving housing (14) for the subassembly (12). The housing (14) is constructed in such a manner that it comprises at least one fluidic connection (24) which, when the pressure generator is in the mounted state, is connected to a fluid inlet (32) or to a fluid outlet (34) of a cylinder block (18) of the pump subassembly (12). The pump subassembly (12) is embodied, preferably, as a multi-piston pump and can comprise an actuation unit (46) for asynchronously actuating the pump piston (28).

摘要： The invention relates to a brake power generator (12; 12a; 12b) for a hydraulic motor vehicle brake system (10) comprising a force input member that is coupled to a brake pedal, a housing (20), and a primary piston (60) which can be displaced within the housing (20) and encloses a primary pressure chamber (78) for generating a hydraulic brake pressure along with the housing, a pedal-simulating device that is coupled to the force input member (22), a device (90) for detecting pedal actuation, and an actuation force booster stage for applying an actuation force onto the primary piston (60). The force input member (22) is mechanically decoupled from the primary piston (60) during normal operation while the actuation force booster stage applies an actuation force onto the primary piston (60) according to the detected pedal actuation, the force input member (22) being coupled in a force-transducing manner to the primary piston (60) in case the actuation force booster stage fails. The primary piston of the brake power generator is provided with a contacting extension (64) which extends to the force input member (22). Said contacting extension (64) is kept at a distance from the force input member (22) by means of an air gap (s) during normal operation while the force input member (22) rests in a force-transducing manner against the contacting extension after penetrating the air gap (s) in case the actuation force booster stage fails.
