The inboard end of the axle shaft is connected to the transmission via a constant velocity joint
(double offset joint: DOJ) which is flexible in the axial directions, while the outboard end is con-

inside the axle housing. The BJ features a large operating angle.
Both the constant velocity joints (DOJ and BJ) ensure smooth, regular rotation of the drive wheels
with minimum vibration.
