The present invention relates to a drive axle assembly improving price competitiveness of a product by improving a coupling structure of a boot and, also, improving design freedom of a wheel sensor. According to the present invention, the drive axle assembly includes: a wheel housing pressurizing an inner race of a wheel bearing by having a cylindrical vertical forming unit formed at an end to be rolled outwards, wherein the wheel bearing is assembled to the outer circumference of the wheel housing; a bearing seal installed between the inner race and an outer race of the wheel bearing; and a boot coupling ring having an encoder integrally formed at one end, and sealed by the bearing seal between the outer race and the inner race. A middle part of the boot coupling ring is attached and fixed in the shape of covering the inner race and the cylindrical vertical forming unit. A large diameter unit of the boot is connected to the other end of the boot coupling ring.

    본 발명은 부트의 체결구조 개선을 통해 제품의 가격경쟁력을 높이고, 휠센서의 설계 자유도를 높이는 드라이브 액슬 조립체에 관한 것으로, 본 발명에서는 외주면에 휠베어링이 조립되고, 단부에 원통형 수직성형부가 바깥으로 말려진 형상으로 형성되어 휠베어링의 내륜을 가압하는 휠하우징; 상기 휠베어링의 외륜과 내륜 사이에 구비되는 베어링씰; 일단에 엔코더가 일체 형성되어 상기 외륜과 내륜 사이에서 베어링씰에 의해 씰링되고, 중간부분이 내륜과 원통형 수직성형부를 덮는 형상으로 밀착 고정되며, 타단에 부트의 대경부가 결합되는 부트체결링;을 포함하는 드라이브 액슬 조립체가 소개된다.
