A constant velocity ball joint uses a star shaped sleeve with a splined connection to its shaft. The sleeve is longitudinally retained on its shaft using a retaining ring in an outwardly facing groove of the shaft. The star shaped sleeve has a 30° assembly assist chamfer angle on one side, as well as a 45° transition chamfer angle and a 65° ramp chamfer angle facing the opposite direction. These angles control the diameter of the retaining ring as it is compressed inward into the groove during assembly and disassembly. The star shaped sleeve can be used in a dynamic length CV joint, with the splines of a configuration that allows longitudinal sliding of the sleeve on the shaft, so the shell of the dynamic length CV joint still can be of the spherical race type.

A swing arm type suspension for a rear wheel of an off road vehicle can use two or three tie rods to control toe-in of the knuckle. The rear end of the swing arm is split between an upper clamping arm and a lower clamping arm defining an eye, with the knuckle connected to the upper and lower clamping arms by joint bearings, and with either the transmission shaft or one of the tie rods extending through the eye of the swing arm to the knuckle. The front of the swing arm can be connected to the vehicle frame using a cross-shaft joint. Camber, toe-in and half-track width are controlled to result in a smaller turning radius with better ride characteristics.
A transmission mechanism of an all-terrain vehicle is provided, which includes an independent suspension axle. The independent suspension axle includes a left driving half-axle and a right driving half-axle. A jaw differential is provided at a joint of the left driving half-axle and the right driving half-axle and is configured to allow half-axles at two sides to rotate at different speeds when the axle of the all-terrain vehicle transmits power to the half-axles at the two sides, and prevent a wheel at one side from slipping. For the all-terrain vehicle adopting the jaw differential, side tipping, side slipping, and tire scuffing are not apt to occur, thus the vehicle may get rid of stuck conditions such as slipping, and the working reliability of the all-terrain vehicle is improved. An all-terrain vehicle adopting the transmission mechanism is further provided.
A half shaft connects to the mounting bracket of the wheel in a splined connection. The straight external spline of the half shaft is modified to a helical or involute external spline, in which the helix angle adopted is small. The mounting bracket of the wheel can be longitudinally advanced by hand assembly only part way onto the half shaft. The rest of the longitudinal advancement during assembly occurs by tightening the nut to completely eliminate the fit clearance between the external spline and its corresponding mating arrangement. Various road tests of vehicles verify that, when using the present invention, the nut does not loosen during use of the vehicle. The invention enables the locking force of the nut to be reduced, and assembly and maintenance are convenient.

A drive shaft is formed by welding two spline shaft heads to a hollow middle section of tubing. The spline shaft head includes teeth which are crowned to permit an angular offset of the drive shaft relative to cylindrical splines of connectors, such that the end faces of the teeth define a barrel shape. The teeth of the spline shaft head include a side face curvature, defining a football-shaped tooth cross-section. Torque is rotationally transmitted across a permitted angular offset of the drive shaft relative to cylindrically arranged linear splines of drive and driven connectors (i.e., relative to the engine output axis of rotation and the differential input axis of rotation), thereby avoiding the use of prior art universal joints.

A mechanical locking differential primarily includes a drive ring and right and left driven rings that can move sideways into and out of engagement with the drive ring. The drive ring and the driven rings have teeth with an inverted trapezoidal shape with a significant clearance, such as a pressure angle of −1° and a clearance of 20% circumferentially. A central ramping separator ring provides a ramping mechanism with inclines that push the driven rings out of engagement with the drive ring when the associated half axle rotates faster than the drive ring, with the ramping action occurring within the teeth clearance.
