Embodiments relate to an off-road vehicle comprising a frame, including at a frame, a passenger compartment, a driveline that includes at least a drive system and a driven system, and a constant velocity (CV) joint for coupling the driven system to the drive system. The CV joint includes a housing, a coupling shaft, a detent, a plunge pin and an actuation pin, wherein the actuation pin has a first end that is accessible via an aperture in the housing, wherein actuation of the actuation pin determines whether the plunge pin is in the first position or the second position.

A wheel drive unit for a vehicle includes a connecting member separably coupled to a constant velocity joint, a hub housing accommodating the constant velocity joint, and a hub cap to seal the hub housing. In particular, a fixing groove is formed around a first end of the constant velocity joint, and the connecting member is fitted in the fixing groove in a ring shape. When the hub cap is separated from the hub housing, the connecting member can be easily disassembled from the constant velocity joint such that inner components of the wheel drive unit can be easily replaced and repaired.

A joint arrangement includes comprising a joint, a nut and an adapter unit. The joint has an inner hub, an outer hub, balls and a cage with recesses for the balls. The inner hub has a recess with an inner toothing for receiving a first shaft. A cavity of the joint arrangement located around the balls is closed on two end sides by a respective sealing device. The adapter unit includes a first adapter portion and a second adapter portion which cooperate to transmit torque across the joint arrangement to or from a second shaft.

A type of constant velocity universal joint has the spline slip structure, including the steel wire retaining ring and the star-shaped sleeve which are both mounted on a common axis, and the steel wire retaining ring limiting device. The said steel wire retaining ring limiting device is a groove arranged on the said star-shaped sleeve and used for holding the said steel wire retaining ring. The said steel wire retaining ring may be elliptic or circular. The movement in the radial direction of the steel wire retaining ring will be limited by the groove on the star shaped sleeve and there occurs a certain contraction, in addition to appropriate the chamfer angle of the groove, when removing the spline shaft from the star-shaped sleeve.

A propeller shaft (1), as a power transmitting shaft, of the present invention is configured such that a snap ring (8) as a retaining ring can be inserted inwards into a first penetration slot (31) formed at a tubular portion body (33) of a tubular portion (30) from a radial direction outer side. With this, good workability of assembly of the snap ring (8) is secured. Further, an engagement-stop state of a second shaft (3) by the snap ring (8) can be visually checked from the outside through the first penetration slot (31), then check of an engagement state by the snap ring (8) can be made.

A universal joint (U-joint) assembly transmits torque from a drive component to a driven component across an articulating joint. The U-joint assembly includes male and female U-joint members, a central ball joint, and a retaining device configured to secure the assembly in an assembled configuration. The female U-joint member includes a cavity extending into a receptacle end thereof. The cavity terminates in a circular receptacle and includes four flat surfaces extending longitudinally therefrom at 90-degree intervals. The male U-joint member has a drive end with four multi-angled surfaces extending longitudinally from the drive end at 90-degree intervals about a periphery of the drive end. When in an assembled configuration, each of the multi-angled surfaces of the drive end of the male U-joint member opposes a corresponding one of the four flat surfaces of cavity of the female U-joint member. Other embodiments are also disclosed.

A propeller shaft assembly comprises a first rotary component having a first splined portion and a first engaging surface arranged transverse to a longitudinal axis of the first rotary component and spaced from the first splined portion and a second rotary component having a second splined portion configured to engage the first splined portion. The second splined portion defines a second engaging surface arranged transverse to the longitudinal axis of the first rotary component. A shear component is disposed between the first engaging surface of the first rotary component and the second engaging surface of the second rotary component. The shear component forms a crash feature of the propeller shaft assembly configured to shear at an edge of the second engaging surface when the first shear component is compressed between the first engaging surface and the second engaging surface.

A constant velocity universal joint includes an outer joint member and an inner joint member between which torque is transferred through intermediation of balls while allowing angular displacement. A power transmission shaft is coupled to the inner joint member to allow torque transmission therebetween. A mounting and dismounting mechanism configured to mount and dismount the power transmission shaft to and from the inner joint member is provided between the inner joint member and the power transmission shaft. The mounting and dismounting mechanism includes a tubular member, a snap ring mounted inside the tubular member, a pushing member arranged on a radially outer side of the snap ring to be movable in a radial direction, and an annular member arranged on an outer peripheral surface of the tubular member to be movable in an axial direction.

Embodiments relate to an off-road vehicle comprising a frame, including at a frame, a passenger compartment, a driveline that includes at least a drive system and a driven system, and a constant velocity (CV) joint for coupling the driven system to the drive system. The CV joint includes a housing, a coupling shaft, a detent, a plunge pin and an actuation pin, wherein the actuation pin has a first end that is accessible via an aperture in the housing, wherein actuation of the actuation pin determines whether the plunge pin is in the first position or the second position.

A shaft assembly. The shaft assembly includes a joint assembly having a first joint member, a second joint member and one or more third joint members drivingly connecting said first and second joint members. At least a portion of a first shaft is drivingly connected to the second joint member. Circumferentially extending from at least a portion of an outer surface of a second end portion of the first shaft is a first and second increased diameter portion having a wall portion that connects the first increased diameter portion to the second increased diameter portion. Drivingly connected to the second increased diameter portion of the first shaft is a second shaft. During a crash condition, an amount of force is applied to the wall portion until it fractures and at least a portion of the first shaft and/or the joint assembly translates into a hollow portion of the second shaft.
