NUCKLE AND DRIVING WHEEL BEARING ASSEMBLY

摘要

A driving wheel bearing assembly is disclosed, which comprises: a wheel bearing integrally and rotationally coupled to a vehicle wheel; a drive member integrally and rotationally coupled to the wheel bearing to receive power of an engine to be transmitted to the wheel bearing; and a knuckle inserting the wheel bearing to be supported. As the knuckle and the wheel bearing individually have assembly grooves which are mutually matched, an assembly bolt is inserted into the assembly grooves for the knuckle and the wheel bearing to be mutually coupled to reliably prevent axial separation of an external wheel and the knuckle.
