A drive axle assembly capable of reducing drag torque by eliminating an inner bearing seal from a wheel bearing and capable of reducing the generation of frictional noise at corrugations of a boot. The drive axle assembly includes a wheel bearing assembled with a wheel housing, an outer ring having a ring shape and including an outer-diameter portion secured to an outer wheel of a wheel bearing, a boot including a large-diameter portion formed at one end thereof and assembled with an inner-diameter portion of the outer ring, and a bearing seal unit disposed between a small-diameter portion formed at the other end of the boot and a drive shaft to restrict rotation of the boot and to prevent introduction of foreign substances.

Drive axle assembly

A hub built-in type drive axle includes one hub housing assuming a role of an external race of a constant velocity joint and a role of a wheel hub simultaneously, wherein the outboard constant velocity joint center is positioned within the full length of the hub housing, and a structure in which a bear housing and a boot assembly ring, including a boot, do not rotate whether the driveshaftrotates is maintained so that performance may be improved, durability may be enhanced, and noise may be minimized.
