An electric caliper comprises a motor having a shaft, and a gear rotatable with the shaft and having at least one tooth projecting therefrom. A plunger is disposed on the shaft, and has at least one socket engagable with a corresponding tooth on the gear. A magnet disposed proximate the plunger is adapted to draw the plunger in a first axial direction, and a solenoid yoke disposed proximate the plunger is adapted to selectively draw the plunger in a second axial direction.

Electromechanical parking brake

A brake vacuum booster assembly is provided that includes a power piston with a two-piece member movable relative thereto for opening a valve when a brake pedal is applied. The two-piece member includes a cylinder and a cylinder cap. The cylinder has a passageway vented to atmosphere for providing air to air chamber in the booster. An electric actuator is retained within a cavity in the cylinder for coacting with the valve to more quickly open the valve during a rapid brake pedal apply. A cylinder cap is connected to an end of the cylinder for retaining the electric actuator within the cavity. The cylinder cap has an opening aligned with the passageway. A retaining mechanism is arranged between the cylinder and the cylinder cap for preventing axial and rotational movement of the cylinder cap relative to the cylinder to securely retain the electric actuator within the cavity and maintain alignment of the opening and passageway.

Vacuum booster with retaining mechanism for cylinder cap

An electric motor where the stator is positioned between motor end caps. The stator comprises a pair of housings that contain coil windings and one of the housings has a plurality of axially extending tabs bent over the other housing to secure the housings from axial separation. The bent over portion of a tab is compressed against a wall of an end cap when the stator is assembled between the end caps of the motor and is bendable to accommodate variations in axial dimensions of the motor. One of the motor housings has additional axially extending tabs that are received within openings formed in an end wall of the motor housing to prevent radial displacement of the stator relative to the motor housing.
