Axle Shaft Assembly: Description and Operation

GENERAL INFORMATION

For the front axle, the unit ball bearing (double-row angular contact ball bearing) with an integral oil seal is used as a wheel bearing, and EBJ-PTJ type constant velocity joint as a driveshaft.
It has the following features:

- The driveshaft incorporates EBJ-PTJ type constant velocity joints with high transmission efficiency for low vibration and noise.
- Dynamic damper is mounted on driveshaft to reduce differential gear noise.[FWD-RH]
- The long stem integrated with the differential side constant velocity joint is adopted to streamline the structure.[AWD-RH]
- Lead-free grease for the constant velocity joint is adopted.
- The number of parts is reduced by integrating the magnetic encoder for ABS wheel speed detection into the wheel bearing.

NOTE:

EBJ (High Efficiency Compact Birfield Joint): the lighter and smaller constant velocity joint compared with the conventional BJ has been achieved by adopting the eight small balls.
PTJ (Pillow Tripod Joint)
