The present invention relates to a housing-integrated axle in which a hub housing coupled to a constant velocity joint is coupled to the inside of a knuckle to be able to rotate by a bearing preload portion. The hub housing comprises: a housing body penetrated; a constant velocity joint coupling portion formed on the inner circumferential portion of the housing body to have a ball guide groove; a bearing preload portion formed on the outer circumferential portion of the housing body; and a bearing outer ring pressure protrusion integrated with a tube fixing groove extending outward on the bearing preload portion and having the knuckle on both sides of the inner circumferential portion thereof. Therefore, by preventing backlash due to a coupling between a hub serration and a stem portion of a constant velocity joint, it is possible to achieve a quicker response through performance improvement of the axle. Therefore, noise and vibration are reduced, and driving and handling of a vehicle are improved.

    본 발명은 하우징 일체형 액슬에 관한 것이다. 이를 위하여, 본 발명은 너클의 내부로 등속 조인트에 결합된 허브 하우징이 베어링 예압부에 의하여 회전 가능하게 결합된 하우징 일체형 액슬에 있어서, 상기 허브 하우징은 관통된 하우징 몸체와; 상기 하우징 몸체의 내주연부에 볼 가이드홈을 갖도록 형성된 등속 조인트 결합부와; 상기 하우징 몸체의 외주연부에 형성된 베어링 예압 가압부; 및 상기 베어링 예압 가압부에 외측으로 연장된 튜브 고정홈이 일체로 형성되고, 상기 너클은 내주연부의 양측에 형성된 베어링 외륜 가압턱으로 구성됨을 특징으로 한다. 따라서, 본 발명은 기존의 등속 조인트의 스템부 및 허브 세레이션 결합에 의한 백래쉬가 발생되는 것을 방지하여 액슬의 성능 향상을 통해 보다 신속한 응답성을 얻을 수 있도록 하고, 이를 통해 소음.진동이 줄어들도록 하고, 아울러 차량의 주행ㆍ핸들링이 향상되도록 한 것이다.
