Abstract
A drive axle assembly provides a maximum bending angle by way of a structure of a shaft bearing supported by a drive shaft with a compact assembly structure. The drive axle assembly is preferably configured to include, a wheel bearing assembled to an axle housing, a boot having a large diameter portion of one end connected to an outer ring of the wheel bearing, a drive shaft having an orbit formed along a circumferential direction of an outer circumferential surface, and a shaft bearing assembled between a small diameter portion of the other end of the boot and the drive shaft, and configured to restrict the rotation of the boot as a rolling element is rotated along the orbit.

A drive axle assembly comprising:
- a wheel bearing assembled to an axle housing;
- a boot having a large diameter portion of one end connected to an outer ring of the wheel bearing;
- a drive shaft having an orbit formed along a circumferential direction of an outer circumferential surface;
- and
- a shaft bearing assembled between a small diameter portion of the other end of the boot and the drive shaft, and configured to restrict the rotation of the boot as a rolling element is rotated along the orbit;
- wherein a shaft seal is assembled to an inboard side of the shaft bearing to block foreign matters from being introduced into the boot;
- wherein the shaft seal is assembled between the small diameter portion of the other end of the boot and the drive shaft;
- wherein the rolling element of the shaft bearing comes into direct contact with the orbit.
