The present invention relates to a rack-driven power assisted steering apparatus, comprising: a bearing; a first elastic member for axially supporting both sides of the bearing to form a first clearance space between a ball nut and the bearing and between a lock nut and the bearing; and a second elastic member supporting both sides of the bearing in the axial direction and the radial direction to form a second clearance space between a lock screw and the bearing and between a rack housing and the bearing. The bearing has an outer ring coupled to the inner side of the rack housing and fixed by the lock screw, and an inner ring coupled to the ball nut and fixed by the lock nut to support rotation of the ball nut inside the rack housing. Therefore, the present invention absorbs loads of various sizes transmitted to the bearing to prevent interference of the bearing with peripheral components.

    본 발명은 랙구동형 동력 보조 조향장치에 관한 것으로, 랙하우징 내측에 결합되어 락스크류로 고정되는 외륜과, 볼너트에 결합되어 락너트로 고정되는 내륜이 구비되어 랙하우징 내측에서 볼너트의 회전을 지지하는 베어링, 베어링의 양측을 축방향으로 지지하여 볼너트와 베어링 사이, 락너트와 베어링 사이에 제1유격공간을 형성하는 제1탄성부재, 베어링의 양측을 축방향 및 경방향으로 지지하여 락스크류와 베어링 사이, 랙하우징과 베어링 사이에 제2유격공간을 형성하는 제2탄성부재를 포함하여 베어링에 전달되는 다양한 크기의 하중을 흡수하여 베어링과 주변 부품들이 부딪치는 간섭을 방지한다.
