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.

The present disclosure provides an inner-C-forging assembly, an integral front axle assembly, and modification method thereof. The inner-C-forging assembly includes an inner-C-forging and a connection structure. The inner-C-forging is configured for connecting with a kingpin knuckle. The connection structure is configured for connecting with an axle tube. The inner-C-forging is detachably fixed to the connection structure, and the inner-C-forging has different mounting states relative to the connection structure. At different mounting states, a kingpin installation portion of the inner-C-forging has different positions relative to the connection structure. In the present disclosure, vehicle's caster angles on both sides and the pinion to driveshaft angle can be conveniently and independently adjusted while ensuring the support strength.

A half-shaft assembly includes a first constant velocity (CV) joint, a second CV joint and an axial movement joint connected between the first CV joint and the second CV joint. The axial movement joint includes a first shaft coupled to the first CV joint and a second shaft coupled to the second CV joint, wherein mechanical input received on the first shaft is communicated to the second shaft, and wherein the second shaft slides axially within the first shaft. The axial movement joint further includes an axial boot cover coupled on a first end to the first shaft and on a second end to the second shaft that accommodates axial movement of the first shaft relative to the second shaft. The first constant velocity (CV) joint is coupled to provide torsional input received at an input to the first shaft, the first CV joint having a first CV boot cover. The second CV joint coupled to provide torsional output received from the second shaft to an output, the second CV joint having a second CV boot cover.

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 tool for transferring a motor vehicle into a rollable state despite a parking lock having been activated includes a base which is fastenable to a vehicle wheel of the motor vehicle and an actuating element which is displaceable along a sliding direction relative to the base and via which, in a state of the base fastened to the vehicle wheel, by displacement of the actuating element along the sliding direction relative to the base, displacing a propeller shaft of the motor vehicle, a toothing engagement between a first toothing of the propeller shaft and a second toothing of a wheel hub can be undone, as a result of which the motor vehicle can be transferred into the rollable state. A travel limiting device specifies a travel by which the actuating element can be displaced at most relative to the base in order to undo the toothing engagement.

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 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.

A portal box assembly for mounting a wheel to an off road vehicle in a lifted and extended wheelbase position. The assembly includes a portal gear box having an input shaft opening for an input shaft, and an output shaft extending from an output shaft opening. The portal gear box also includes a set of gears effective to transmit power from the input shaft to the output shaft, and optionally to reduce the gear ratio. The assembly is mountable to the vehicle in an extended wheelbase position in which the output shaft is positioned below and forward of the input shaft when the assembly is used to mount a forward wheel, and in which the output shaft is positioned below and rearward of the input shaft when the assembly is used to mount a rear wheel.
