According to the present embodiments, provided is a rack-driven power assisted steering device in which a rolling member supporting the rotation of a ball nut is provided in a double row, a ball nut assembly is coupled to a housing through an elastic member, the flow of the ball nut is absorbed to improve noise performance, and the rolling member is directly supported by the ball nut or a support member, so that the number of parts can be reduced and easy assembly is possible.

    Dans des modes de réalisation, l'invention concerne un dispositif de direction assistée entraîné par crémaillère, dans lequel un élément roulant soutenant la rotation d'un écrou sphérique est disposé dans une double rangée, un ensemble écrou sphérique est couplé à un logement par l'intermédiaire d'un élément élastique, le mouvement de l'écrou sphérique est absorbé pour que soient améliorées les performances de bruit, et l'élément roulant est soutenu directement par l'écrou sphérique ou par un élément de support, de sorte que le nombre de pièces puisse être réduit et qu'un assemblage facile soit possible.

    본 실시예들에 의하면, 볼너트의 회전을 지지하는 구름부재가 복열로 구비되고 볼너트조립체가 하우징에 탄성부재를 매개로 결합되며 볼너트의 유동이 흡수되어 노이즈 성능이 개선되고, 구름부재가 볼너트 또는 지지부재에 직접 지지되어 부품 수가 감소되고 용이하게 조립이 가능한 랙구동형 동력 보조 조향장치가 제공될 수 있다.
