Axle Shaft Assembly: Description and Operation

Front Axle




- The inboard end of the axle shaft is connected to the transmission via a constant velocity joint (double offset joint: DOJ) which provides flexible capabilities in the longitudinal direction while the outboard end is supported by taper roller bearings located inside the housing via a under cut free joint (UFJ) which features a large operating angle.
Since the drive shaft employs constant velocity joints, it provides smooth, even rotation of the drive wheels without any vibration.
- The bearing utilizes a preloaded, non-adjustable tapered roller unit design. The hub is fitted to the tapered roller bearing inside the housing.
- The UFJ's spindle is "serration-fitted" to the hub and is clinched to it with axle nuts.
- The disc rotor is an external mounting type. It is secured together with the disc wheel using hub bolts to facilitate maintenance of the disc rotor.


FRONT DRIVE SHAFT







- The constant-velocity joint on the differential side is a double offset (DOJ) type which can be disassembled for maintenance. It provides the maximum operating angle of 23° and can also be moved in the axial direction.
- The constant-velocity joint on the tire side is an extra-wide, undercut free type (UFJ) which provides a maximum operating angle of 50°.
- On 95AC, resin UFJ boots are adopted to improve durability.
