A differential includes a driven body, an output element, and a clutch assembly radially interposed between the driven body and the output element. The clutch assembly includes a first wedge clutch configured to rotationally lock the output element to the driven body in a first direction and to overrun in a second direction, and a second wedge clutch configured to rotationally lock the output element to the driven body in the second direction and to overrun in the first direction.

A roller cage assembly for an overrunning clutch is provided. The roller cage assembly includes a roller cage, a plurality of rollers and a plurality of roller spring assemblies. The roller cage includes a plurality of spaced support members axially extending between disk shaped first and second end portions. The plurality of rollers are positioned within the roller cage. The plurality of roller spring assemblies engage the roller cage. The plurality of spring roller assemblies are configured to provide a bias force on each roller away from the roller cage. Each roller cage assembly extends between the first and second end portions of the roller cage. Each roller spring assembly further includes at least one pair of attachment members configured to engage a support member of the roller cage.

An overrunning clutch (ORC) differential is provided that includes a locking mechanism that is configured to lock rotation of a clutch cam housing to a roller cage to retain a centering of each roller in an associated cam roller feature to prevent torque from being communicated between the clutch cam housing and first and second hubs when the locking mechanism is activated.

A bi-directional overrunning clutch differential is configured to transmit power from an input shaft to a first output shaft and a second output shaft in a vehicle. The differential includes a differential housing having a first bearing seat and a second bearing seat. A first bearing is carried by the differential housing in the first bearing seat, and a second bearing is carried by the differential housing in the second bearing seat. A first retaining ring secures the first bearing in the first bearing seat, and a second retaining ring secures the second bearing in the second bearing seat. A first output hub is carried by the first bearing for rotation relative to the differential housing, and a second output hub is carried by the second bearing for rotation relative to the differential housing.

A clutch unit for a drive unit, comprising: at least one outer ring and one inner ring, wherein the rings are mounted rotatably relative to each other, the outer ring being configured to be in operative engagement with a first component of a drive unit of a vehicle and the inner ring being configured to be in operative engagement with a second component of a drive unit of a vehicle; at least one first locking element; at least one first displacement element; the at least one first locking element being movably mounted on one of the rings and being movable by the displacement element in order to engage in a corresponding recess of the other ring a rotationally fixed connection of the two rings in at least a first direction of rotation being provided.

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.

A transaxle according to the present application may include: a transaxle case; an input member supported within the transaxle case; a gear drivingly connected to the input member within the transaxle case; an output member which is supported within the transaxle case and arranged at the inner peripheral side of the gear concentrically with the gear; a cage with a roller as a bidirectional overrunning clutch interposed between the inner periphery of the gear and the outer periphery of the output member within the transaxle case; and a drag mechanism provided within the transaxle case to apply rotational resistance to the cage to make the bidirectional overrunning clutch be engaged. The cage has a first end and a second end, which oppose each other in an axial direction of the output member. The first end of the cage is close to a first bearing which pivotally supports the output member to the transaxle case. The drag mechanism has a rotation member which is locked to the cage at the first end of the cage so as to be relatively non-rotatable, and a spring member for applying the rotational resistance to the rotation member.

A gearless differential for distributing power from a motor to two follower shafts with ends connected to opposite wheels and to opposed outer disks held in position with a journal mounted casing having corresponding identical regular polygonal raceways with asymmetric sections surrounding a central drive disk there between with equidistant radial slots each holding one cylinder or roller bearing to radially reciprocate as they race along the raceways in a slippage mode where one wheel loses traction; and in a drive mode where the central drive disk power input drives both outer disks connected to the two follower shafts transferring torque evenly to both wheels so there is no movement of the cylinders or roller bearings in the raceways.
