A disconnect including: an input hub; an output race including a radially inner surface with ramps; wedge plate segments radially disposed between the input hub and the output race, each segment including a ramp in contact with an outer race ramp; an actuator cage; and an actuator plate. For a connect mode, the input hub, the wedge segments, and the output race transmit torque from an electric motor of an electrically-powered vehicle to a wheel of the vehicle. In a disconnect mode, relative rotation between the input hub and the output race is enabled. To transition from the connect mode to the disconnect mode: the actuator plate is displaced by an actuator; the actuator plate axially displaces the actuator cage; and the actuator cage circumferentially displaces the wedge plate segments to decrease or break frictional contact between the wedge plate segments and the input hub.

A clutch includes an inner race, an outer race defining an inner cam surface having lobes and valleys, and a plurality of wedge segments configured to selectively couple the inner and outer races. The wedge segments are circumferentially arranged around the inner race with each segment disposed between adjacent ones of the lobes and valleys. Each segment is circumferentially movable towards the adjacent lobe to increase friction with the inner race and towards the adjacent valley to decrease friction with the inner race. A cage is configured to drive the circumferential movement of the wedge segments. Rotation of the cage relative to the outer race in a first direction permits overrunning of the inner race in a second direction that is opposite the first direction while a second set of the segments locks the inner race from rotating in the first direction relative to the outer race.

A wedge clutch includes an inner race and an outer race circumscribing the inner race. A wedge element is radially disposed between the inner and outer races and actuatable to couple and decouple the inner and outer races. An actuator is operably coupled with the wedge element and is configured to actuate the wedge element to decouple the inner and outer races.

A differential with an overrunning clutch (ORC) assembly is provided. The differential includes a first plain bearing end cap with an interior surface that forms a plain bearing interface with an outer surface of a first side hub. The first plain bearing end cap further has a first outer surface portion that engages a first end portion of a roller cage assembly. A second plain bearing end cap with an interior surface that forms a plain bearing interface with an outer surface of the second side hub is also included. The second plain bearing end cap further has a first outer surface portion that engages a second end portion of the roller cage assembly. The (ORC) assembly selectively engages the roller cage assembly during an ORC condition to selectively couple torque between a ring gear and the first and second side hubs.

Disclosed is an electromechanical disc brake. The electromechanical disc brake includes a piston slidably disposed in a cylinder of a caliper housing to press a pad plate, an actuator including a motor and a speed reduction device for reducing a rotation speed of the motor, an output conversion device for converting a rotational motion from the speed reduction device into a linear motion and imparting a thrust to move the piston, an elastic member for moving the output conversion device to the original position when releasing braking, and a clutch device for releasing a torque acting on the speed reduction device such that the output conversion device is moved to the original position by the elastic member when releasing the braking.

A steering column assembly includes a steering shaft operatively coupled to a steering device, the steering shaft and the steering device having corresponding rotation with each other. Also included is an anti-rotation assembly selectively engaged with a surface of the steering shaft to maintain the steering shaft and the steering device in a stationary condition when the steering shaft is rotationally decoupled from road wheels operatively coupled to the steering shaft.

A clutch assembly for selectively transmitting torque between an engine and a torque converter is provided. A first plate is non-rotatably connected to a torque converter cover. A second plate is configured to receive a torque input from an engine. A wedge clutch is disposed axially between the first and second plates and is configured to selectively transfer torque between the first plate and the second plate. The wedge clutch includes wedge segments that are configured to collectively radially expand and contract to selectively transfer torque between the first plate and the second plate.

A wedge clutch includes an inner race and an outer race. The outer race defines an inner cam surface. A chain of wedges encircles the inner race and are configured to couple the races when the clutch is engaged. The wedges have outer surfaces that match with sections of the inner cam surface such that the wedges have an outer radial position when in first rotational position relative to the cam surface and have an inner radial position when in a second rotational position to frictionally engage the inner race.
