摘要： A differential device includes: a pinion gear; a pinion shaft for rotatably supporting the pinion gear; a pair of side gears, which engage with the pinion gear and are fitted to a pair of drive shafts; a differential case, which supports the pinion shaft, houses the pinion gear and the side gears, and has an opening on one side of the drive shafts; and a differential cover, which has a hole through which one of the drive shafts penetrates, is fixed to the differential case, and closes the opening. Further, the differential cover has an oil passage which penetrates along the hole from an inner surface facing the side gears to an outer surface opposite to the differential case and through which a lubricating oil flows.

摘要： An axle assembly with a housing, a shaft received in the housing, a shaft bearing supporting the shaft for rotation relative to the housing about a shaft axis, a differential assembly, an annular band and a secondary retainer. The shaft bearing has an inner race, which is received on and directly engaged to the shaft, and an outer race that is received on and directly engaged to the axle housing. The differential assembly has an output member that is non-rotatably coupled to the shaft. The annular band is fixedly coupled to the shaft at a location along the axle shaft axis between the inner race and the output member. The secondary retainer is disposed along the axle shaft axis between the annular band and the output member and is configured to limit movement of the annular band along the axle shaft axis in a direction toward the output member.

摘要： A ball and ramp assembly including a first plate, a second plate and one or more rolling elements between the first and second plates. The first plate includes a shoulder portion that extends from a first side of the first plate. Additionally, the first plate includes an increased diameter portion that extends from an outer surface of the first plate. Extending inward from a second side of the first plate is a receiving portion with a substantially vertical wall portion having one or more non-circular first plate grooves. The second plate has one or more non-circular second plate grooves that extend along a first side of the second plate. The second plate grooves are a reverse mirror image of the first plate grooves. Radially outboard from the shoulder portion is a thrust bearing and integrally connected to the outer surface of the first plate is a first plate gear portion.

摘要： A differential gear mechanism includes a differential case, a first side gear, a second side gear, a first pinion and a second pinion. The first side gear is rotatably mounted within the differential case and has a first outer diameter. The second side gear is rotatably mounted within the differential case and has a second diameter. The first pinion gear is meshed for rotation with the first side gear during a first meshing event. The second pinion gear is meshed for rotation with the second side gear during a second meshing event. The first and second pinion gears form a torque transfer arrangement configured for transferring torque between the first and second pinion gears and the first and second side gears to rotate the first and second side gears. The first and second outer diameters are distinct such that the first and second meshing events are offset in time.

摘要： In at least some implementations, a differential for a vehicle includes a pinion gear, a pair of side gears and a housing. The side gears are meshed with the pinion gear and the housing defines a cavity in which the pinion gear and side gears are received. The housing also has an opening with an inner end leading to the cavity and an outer end spaced from the inner end. The opening is adapted to receive a shaft therethrough for coupling of the shaft to one of the side gears and the opening is defined at least in part by a journal surface. The journal surface is concave with respect to the shaft and provides a converging portion from the inner end to a central portion between the inner end and outer end and a diverging portion from the central portion to the outer end.

摘要： The present teachings provide for a vehicle drive module including a housing, an electric motor, a transmission gear set, a differential assembly, and a pair of output members. The transmission gear set can transmit rotary power between a motor output shaft and an output of the transmission gear set. The differential assembly can include a case, a pair of pinion gears, and a pair of side gears. Each of the side gears can be meshingly engaged with the pair of pinion gears. Each output member can include a driven body and an outer flange. The driven body can have a first end drivingly coupled to one of the side gears. The outer flange can have a first side that is releasably coupled to the second end of the driven body, and a second side that is adapted to be releasably coupled to a constant velocity joint.
