The present invention relates to an axle apparatus for a driving wheel of a vehicle. A main objective of the present invention is to provide an axle apparatus for a driving wheel of a vehicle capable of resolving problems such as locknut loosening, caulking nut loosening, and a joining problem in a coupling unit between a wheel hub and a driveshaft. To achieve the objective, the axle apparatus for a driving wheel of a vehicle comprises: a steering knuckle connected to a steering apparatus; a wheel hub coupled to the inside of the steering knuckle; a wheel disk fixed on the wheel hub to rotate as one unit; a driveshaft coupled to rotate with the wheel hub as one unit; and a hub bearing coupled to be positioned between the steering knuckle and the wheel hub. A forming unit of a bent shape to protrude to the outside in a radial direction is formed on an end of the wheel hub while an inner race of the hub bearing is coupled to the outer circumferential surface of the wheel hub. The inner race is laterally stopped by the forming unit while the forming unit is tightly attached to a lateral end of the inner race to integrally couple the wheel hub and the inner race.

    본 발명은 차량의 구동륜 액슬장치에 관한 것으로서, 휠허브와 드라이브 샤프트 사이의 결합부에서 나타나는 이음 발생 문제, 백래시, 코킹너트 풀림, 로크너트 풀림 등의 문제점이 해소될 수 있는 차량의 구동륜 액슬장치를 제공하는데 주된 목적이 있는 것이다. 상기한 목적을 달성하기 위해, 조향장치와 연결되는 조향너클; 상기 조향너클 내측으로 결합되는 휠허브; 상기 휠허브에 일체로 회전하도록 고정되는 휠디스크; 상기 휠허브와 일체로 회전하도록 결합되는 드라이브 샤프트; 및 상기 조향너클과 휠허브 사이에 위치하도록 결합되는 허브 베어링을 포함하며, 상기 허브 베어링의 내륜이 휠허브의 외주면에 결합된 상태에서 휠허브의 단부에 반경방향의 바깥쪽으로 돌출되도록 꺾인 형상의 포밍부가 형성되고, 상기 휠허브와 내륜이 일체로 결합되도록 포밍부가 내륜의 측단부에 밀착된 상태에서 상기 내륜이 포밍부에 의해 측방으로 걸려 있는 것을 특징으로 하는 차량의 구동륜 액슬장치가 개시된다.
