An outer ring assembly adapted for a one way clutch bearing assembly is provided. The outer ring assembly includes two separately formed rings. A first outer ring includes a groove adapted to receive a plurality of locking wedges, and a second outer ring includes an outer race adapted to support a plurality of rolling elements. The outer ring assembly is installed with a one way clutch bearing assembly including an inner ring defining both an inner race adapted to support rolling elements, and a plurality of ramps axially spaced from the inner race.

A wedge clutch includes a drawn outer cup that axially contains the inner components of the clutch. In particular embodiments disclosed herein, a wedge clutch includes an inner race such as a hub, an outer race such as a carrier, and a plurality of wedge segments radially therebetween. The wedge segments are arranged and moveable about a central axis, and can move into and out of a wedging engagement between the inner race and outer race to transfer torque therebetween. A unitary, single drawn cup is flanged to axially contact and border the outer race and the wedge segments. This contains the outer race and the wedge segments axially, to improve operation of the clutch and create a unitized wedge clutch.

In an actuator having a reversible motor before a step-down gear, this can be optimized kinetically, geometrically and in terms of material engineering when different step-down ratios become active according to the different torque requirement for application and for release, in a manner dependent on direction of rotation, for example of a parking brake operated by an electric motor. For this purpose, two differently dimensioned idler wheels of the step-down gears that mesh, for example, with a stepped motor pinion, act via freewheels acting in opposite directions on a common gear shaft. Depending on direction of rotation of the motor, the gear shaft thereby rotates at different rpms, delivering correspondingly different torques.

A clutch, including: inner and outer races; a wedge plate; an electromagnetic actuator including a coil and an attenuating circuit. The coil is arranged to be energized by a power source to switch the wedge clutch between: a locked mode in which the inner and races are locked in a circumferential direction and a free-wheel mode in which the inner race is rotatable with respect to the outer race in the circumferential direction. The attenuating circuit includes a capacitor parallel with the coil and a switch wired to the capacitor. During the free-wheel mode: the switch is arranged to connect the capacitor to an electrical ground; and the electrical power source is arranged to energize the coil and charge the capacitor with a voltage. Following initiation of the locked mode: the switch isolates the capacitor from the electrical ground; and the capacitor discharges the voltage through the coil.
