A torque transmitting device for transmitting torque between a first and second members includes an annular piston that defines an axis and an apply plate translatable along the axis between an unengaged position and an engaged position. The apply plate has a first end disposed radially inward of a second end and is in contact with the piston. An apply disc is rotationally coupled to the first member and is translatable between unengaged and engaged positions. The apply disc is disposed radially outward of the piston. A backing disc is rotationally and axially fixed to the first member and disposed radially outward of the piston. A friction plate is disposed between the apply disc and the backing disc. The friction plate has a first end disposed radially inward of a second end and is rotationally coupled to the second member. The friction plate is disposed radially outward of the piston.

Compact torque transmitting assembly

A support structure for a differential assembly comprising: a support ring having a peripheral wall extending between a first face and a second face, the support ring having a non-hollow center; a bore in the peripheral wall sized and shaped to receive a pinion shaft; and an aperture in the first face, the second aperture in fluid communication with the first aperture.

Support structure for differential

A pin retention and assembly system that is used with vehicles, such as, off-road vehicles is provided. The pin retention and assembly system has modular locking pins engaging a collar positionable about a bearing journal of a differential housing. Channels are formed in the bearing journal for receiving the locking pins. The channels aid in maximizing the size of the bearing journal. The locking pins engage the collar to lock the differential housing. In an embodiment, the locking pins and locking apertures in the differential housing are orientated asymmetrically causing the number of locking pins to be independent to the apertures in the side gear.

Pin retention and assembly system for locking differential

The present invention provides a differential housing having guide slots formed therein. The guide slots permit movement of pinion shaft axially therethrough. A plurality of apertures are provided in the housing for properly positioning a pinion shaft within the housing. The apertures further provide fluid communication between the exterior and the interior of the housing to aid in adequately lubricating the components within the differential housing.
