Abstract
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 differential comprising:
- a driven body;
- an output element;
- and
- a clutch assembly radially interposed between the driven body and the output element and including 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 differential comprising:
- a driven body;
- a first output shaft configured to couple with a half shaft;
- a first forward wedge clutch configured to, when engaged, rotationally lock the first output shaft to the driven body in a reverse direction of the first output shaft and to permit rotation between the first output shaft and the driven body in a forward direction of the first output shaft;
- a first reverse wedge clutch configured to, when engaged, rotationally lock the first output shaft to the driven body in the forward direction of the first output shaft and to permit rotation between the first output shaft and the driven body in the reverse direction of the first output shaft;
- a second output shaft configured to couple with another half shaft;
- a second forward wedge clutch configured to, when engaged, rotationally lock the second output shaft to the driven body in the reverse direction of the second output shaft and to permit rotation between the second output shaft and the driven body in the forward direction of the second output shaft;
- and
- a second reverse wedge clutch configured to, when engaged, rotationally lock the second output shaft to the driven body in the forward direction of the second output shaft and to permit rotation between the second output shaft and the driven body in the reverse direction of the second output shaft.
