[Problem] To provide an electric booster that can mechanically exhibit a jump-in characteristic and a hysteresis characteristic without relying on control software. [Means for Resolution] An electric booster 3 includes an electric motor 9; a power piston 1...

The system (100) has an actuator piston (140) including a rear shoulder (151) forming a stop against which a thrust flange (143) of the piston rests, for driving the piston during normal operation. An assistance piston (150) freely advances with respect to...

A brake fluid pressure electrically generated by a slave cylinder (23) in accordance with an operation amount by a brake pedal (12) is supplied via a VSA system (24) to wheel cylinders (16, 17; 20, 21) provided respectively for wheels. This enables smooth ...

The servo-motor (1) has an electric motor (2) whose clutch shaft (4) extends along a central axis (5). A push rod extends along another central axis (6). Driving units drive the rod, and are formed of wheels (7, 8) and pinions (9, 10). The driving units co...

[TASK] It is an object to provide a brake device and a method of controlling the brake device, capable of suppressing an inrush current during a startup period of an electric booster. [MEANS TO SOLVE] In a brake device having an input rod, a piston for pre...

The method involves using supportively the parking brake unit depending on motor- or transmission parameters in predetermined operating condition of the vehicle. An electronic parking brake provided in the vehicle is used as a parking brake device. The par...

For forming an anti-rotation device, a region of the linearly guided component of the threaded spindle/threaded nut arrangement is provided with a cylindrical guide profile, which interacts with a complementary profile that is fixed relative to the housing...

A rotor (5) acts on a first piston (9) sliding in a first cylinder (8). A second, preferably larger, piston (20) sliding in a second cylinder (19) acts on a brake lining (21). The first and second cylinders connect to each other and are filled with fluid. ...
