An axle assembly having a clutch collar actuator mechanism. The clutch collar actuator mechanism may have a piston housing and a yoke that may move with respect to the piston housing. The piston housing may extend around the input shaft and may receive at least one piston. The yoke may connect the piston to the clutch collar.

A differential gear assembly for a vehicle includes: an annular ring gear having internal and external surfaces, and rotates around a rotational axis extending in an axial direction; first and second side gears respectively distribute a first and second output torque to first and second drive shafts; first and second differential pinion gears respectively engage the first and second side gears; a pinion pin extends diametrically across the ring gear, where the first and second differential pinion gears are rotatably arranged on the pinion pin. The ring gear comprises first and second slots for receiving the pinion pin, where the slots are arranged in connection to the internal surface and extend partly through the ring gear in the axial direction.

A vehicle differential assembly includes a differential housing including an outer surface and a driveshaft mounting end having a terminal end portion. A differential gear set is rotationally supported within the differential housing. A pinion gear is arranged in the differential housing. The pinion gear includes a head end drivingly connected to the differential gear set and a tail end extending through the driveshaft mounting end. A head bearing is arranged within the driveshaft mounting end. The head bearing supports the head end of the pinion gear. A tail bearing is supported by the outer surface of the differential housing. The tail bearing is configured and disposed to support the tail end of the pinion relative to the driveshaft mounting end.

A differential device for a 4-wheel-drive vehicle wherein a portion of a drive power source drive force transmitted to left and right main drive wheels is transmitted to left and right auxiliary drive wheels through a propeller shaft which is disconnectable from a power transmitting path between the main drive wheels and drive power source, the differential device distributes the drive force from the propeller shaft to the auxiliary drive wheels, and selectively connects and disconnects the propeller and an output shaft to and from each other, the output shaft. The differential device includes a side oil seal between the output shaft and a casing, a side bearing adjacent to the seal in an output shaft axial direction such that the output shaft is rotatably supported by the casing via the bearing, and an oil slinger axially adjacent to the bearing so the slinger is rotated with the output shaft.

The present disclosure provides a differential gear to be mounted on a vehicle, including a pair of side gears, at least two pinion gears meshed with the side gears, and a differential case that houses the side gears and the at least two pinion gears. Lubricating oil is supplied to and discharged from the inside of the differential case via an opening portion. The differential case includes at least two seat surfaces formed on the inner peripheral surface of the differential case so as to support the pinion gears, weir portions provided between the adjacent seat surfaces and extending in a direction along the rotational direction of the differential case to connect between the adjacent seat surfaces, and an oil reservoir portion formed on the inner peripheral surface by the weir portions so as to be positioned on the opposite side, in the axial direction of the side gears, of the opening portion from the weir portions. Consequently, it is possible to render the differential gear compact by suppressing a shortage of lubricating oil for a sliding portion well.

A differential gear arrangement for a vehicle. The differential gear arrangement includes a ring gear, a spindle gear, a spindle gear carrier, a side gear and an output shaft. The spindle gear is carried by the spindle gear carrier and rotatable relative to the spindle gear carrier. The spindle gear and the side gear are engaged with each other. The side gear is rotationally connected to the output shaft. The ring gear is arranged to drive the output shaft by rotating the spindle gear carrier when the ring gear and the spindle gear carrier are rotationally connected to each other. The ring gear and the spindle gear carrier are rotationally disconnectable from each other by axial displacement of the spindle gear carrier relative to the ring gear and the output shaft.

In a differential device including: a first transmission member having a first axis an eccentric rotating member in which are joined a hollow first output boss and an eccentric shaft portion; a second transmission member rotatably supported on the shaft portion; a third transmission member having a hollow second output boss rotatable around the first axis and facing the second transmission member; a first speed change mechanism between the first and second transmission members; and a second speed change mechanism between the second and third transmission members, one of mating faces of a first hub of a differential case and a first drive shaft fitted and supported in the hub is provided with a helical groove that can draw in lubricating oil within a transmission case. An oil passage communicating the groove with the first speed change mechanism is provided between the differential case and the rotating member.

A vehicle having a structure is provided. The system includes a cradle mounted to the structure at a first position and a second position, the second position being spaced apart from the first position. A rear drive module is provided having a housing, the housing coupled to the cradle between the first position and the second position, the housing coupled to the cradle in at least two locations. At least one linkage is operably coupled to the housing on a first end and to the structure on a second end.
