Abstract:
1. An electrically operable brake drive for a vehicle having wheels, having braking apparatus for applying a braking force to at least one of the wheels to thereby set a brake of the vehicle and for reducing the applied braking force to thereby release the brake of the vehicle and having a force transmitting means for coupling the braking apparatus to the drive, said brake drive comprising: a plurality of drivingly coupled and rotatable gears, one of the gears including coupling means for coupling one of the gears to the force transmitting means for setting and releasing the brake depending on the direction of rotation of said one of the gears; an electrically operable motor with a rotatable and reversible drive member coupled to a gear of the plurality of gears and alternatively rotatable in a first direction for rotating the gears in the brake setting direction and in a second, opposite direction for rotating the gears in the brake releasing direction; a detent mechanism coupled to the gears for preventing rotation of the gears in the brake release direction when the drive member is rotated in the first direction and for permitting rotation of the gears in the release direction when the drive member is rotated in the second direction; and an electrical control system for controlling the direction of rotation of the drive member for setting and releasing the brake without manual readjustment of the drive.
