An adjustable front axle includes an axle housing; an axle tube connected to an end of the axle housing; an inner-C-forging disposed on the axle tube at an end away from the axle housing; and a mounting apparatus configured for detachably fixing the inner-C-forging to the axle tube. The inner-C-forging is provided with a first angle adjustment structure, the axle tube is provided with a second angle adjustment structure. The mounting apparatus is disposed on the axle tube, and capable of cooperating with the inner-C-forging to fix the inner-C-forging to the axle tube. The first angle adjustment structure and the second angle adjustment structure have different cooperation positions such that the inner-C-forging has different installation angles relative to the axle tube. A vehicle is also provided.

Axle assembly includes first and second axle housings extending toward opposing sides of a vehicle frame with the axle housings aligned to define an axle axis, first and second wheel ends, first and second drive shafts disposed within the first and second axle housings, a gearbox having a first surface facing one side of the vehicle frame and a second surface facing the other side of the vehicle frame with the gearbox cantilevered outwardly relative to the aligned axle housings to define a gearbox axis parallel to a longitudinal axis of the vehicle frame and transverse to the axle axis, and an electric motor coupled to the second surface of the gearbox and extending toward the first side of the vehicle frame to define a motor axis that is parallel to and offset from the axle axis, transverse to the gearbox axis, and transverse to the longitudinal axis.

A wheel drive assembly for transferring propelling torque from a source shaft to a wheel, the source shaft receiving torque from a motion actuator. The wheel drive assembly includes a wheel-hub, adapted to have the wheel mounted thereon, the wheel-hub being arranged about a longitudinal axis, which is adapted to coincide with a rotation axis of the wheel. The wheel drive assembly further includes a drive axle and a constant velocity (CV) joint mounted onto an outer end of the drive axle. The CV joint connects the drive axle to the wheel-hub. An outermost surface of the CV joint is disposed outwardly of an outermost surface of the wheel hub, along the longitudinal axis of the wheel-hub.

A motor vehicle shaft assembly has a shaft extending along a longitudinal axis between opposite ends, with the shaft having a male spline adjacent at least one of the opposite ends, and a housing having a through bore extending about the longitudinal axis, with the through bore having a female spline configured for meshed engagement with the male spline to prevent relative torsional movement between the shaft and the housing. At least one of the male and female splines includes a tapered spline extending in oblique relation to the longitudinal axis.

A wheel end assembly includes a hub connectable with a wheel and having a bore for receiving a shaft. An inboard bearing within the bore includes an outer ring coupled with hub, an inner ring within the outer ring and rolling elements. A seal assembly is coupled with the inner ring and retains the inner ring within the outer ring when the end assembly is separate from the shaft. An outboard bearing within the hub bore includes an outer ring coupled with the hub, an inner ring within the outer ring and rolling elements. A nut assembly is disposed adjacent to the outboard bearing and includes a nut threadably engaging the shaft. A retainer retains the nut assembly adjacent to the outboard bearing to limit axial displacement of the outboard inner ring to maintain the inner ring within the outer ring when the wheel end is separate from the shaft.

An adjustable front axle includes an axle housing; an axle tube connected to an end of the axle housing; an inner-C-forging disposed on the axle tube at an end away from the axle housing; and a mounting apparatus configured for detachably fixing the inner-C-forging to the axle tube.
