The present invention relates to a vehicle drive axle with a sealing performance improving function and, particularly, to a vehicle drive axle with a sealing performance improving function, which can seal a sensor portion without adding other separated components to block inflow of external impurities or foreign substance and prevent sensing performance degradation. The vehicle drive axle includes: a drive shaft; a knuckle supporting a wheel bearing and a seal; and boots, wherein the boots has a sealed part with one end formed to be extended long in the radial direction of the wheel bearing, and the wheel bearing is formed to have the extended length so that one cross section of an outer ring comes in contact with the sealed part of the boots.

    본 발명은 밀폐성 향상 기능을 갖는 차량용 드라이브 액슬에 관한 것으로서, 특히 별도의 부품 추가 없이 센서 부분을 밀폐시킬 수 있도록 하여 외부 불순물이나 이물질의 유입을 차단하고 센싱 성능의 저하를 방지하도록 하는 밀폐성 향상 기능을 갖는 차량용 드라이브 액슬에 관한 것이다. 구성은 드라이브 샤프트와 휠베어링과 실(seal)을 지지하는 너클 및 부츠를 포함하는 차량용 드라이브 액슬에 있어서, 상기 부츠는 일단 부분이 휠베어링의 경방향으로 길게 확장 형성되는 밀폐부를 형성하고, 상기 휠베어링은 아우터링의 일단면이 상기 부츠의 밀폐부와 접하도록 길이가 연장형성 되는 것을 특징으로 한다.
