Parking brake, notably for automatic transmission systems of motor vehicles

摘要

Parking brake, notably for automatic transmissions of motor vehicles, which is released via hydraulic pressure acting on a spring accumulator (3) and which is additionally held in the released state by a locking system (13) is actuated by a magnet (5) through which a current flows. The locking system (13) is kept activated and thus the parking brake released until the magnet (5) in the position in which the locking system (13) is actuated, has a power consumption lower than necessary for loading the locking system (13).
