ELECTRICALLY OPERABLE VEHICLE PARKING BRAKE DRIVE

摘要

An electrically or manually operable brake drive for the brakes of a vehicle which has a gear train optionally driven by a reversible electric motor or a manual member. The brakes can be set or released by the electric motor without manual changing of the drive components permitting setting and releasing of the brakes at a location remote from the drive. For maintaining the brakes in a "set" mode, the drive includes a gradual release detent mechanism which permits rotation of the gears in the brake setting direction but opposes such rotation in the opposite direction unless a drive shaft rotatable by the motor or the manual member is rotated in the brake release direction.
