Parking brake system, especially for motor vehicles, has auxiliary hydraulic piston that can be loaded against force of spring and that interacts with electromechanical control device

摘要

The system has an actuator for producing an electronic signal, an electronic controller that receives the actuator signal and processes it into a drive signal and an arrangement (1) for converting the drive signal into a control movement of a braking device and for reversible mechanical locking of the braking device in its clamped position. The arrangement has an auxiliary hydraulic piston (4) that can be loaded against the force of a spring (6) and that interacts with an electromechanical control device (2,3).
