Title (EN) ELECTRIC POWER STEERING SYSTEM
(FR) SYSTÈME DE DIRECTION À ASSISTANCE ÉLECTRIQUE
(KO) 전동식 파워 스티어링 시스템
Abstract:
(EN) An electric power steering system according to an embodiment of the present invention comprises: a housing having a reception space formed therein; a worm shaft disposed in the reception space and meshing with a worm wheel; a tilt plug coupled and fixed to an inner surface of the housing at a predetermined position, and coupled to and supporting the worm shaft which is inserted into the reception space; and an elastic support part installed in the housing and elastically supporting the tilt plug toward the worm wheel, wherein the tilt plug has a coupling protrusion formed thereon and protruding from the end thereof toward the central axis thereof so as to be slidingly inserted in the inner surface of the housing, and the housing has a coupling groove formed on the inner surface thereof into which the coupling protrusion is allowed to be inserted, thereby restraining the rotation of the tilt plug.
(FR) Un système de direction à assistance électrique selon un mode de réalisation de la présente invention comprend : un boîtier comprenant un espace de réception formé en son sein ; un arbre à vis sans fin disposé dans l'espace de réception et s'engrenant avec une roue à vis sans fin ; un bouchon d'inclinaison accouplé et fixé à une surface interne du boîtier à une position prédéfinie, et accouplé à l'arbre à vis sans fin qui est inséré dans l'espace de réception et supportant celui-ci ; et une partie de support élastique installée dans le boîtier et supportant élastiquement le bouchon d'inclinaison vers la roue à vis sans fin, une saillie d'accouplement étant formée sur le bouchon d'inclinaison, laquelle fait saillie à partir de son extrémité vers son axe central de sorte à être insérée coulissante dans la surface interne du boîtier, et le boîtier présentant une rainure d'accouplement formée sur sa surface interne, dans laquelle peut être insérée la saillie d'accouplement, ce qui limite la rotation du bouchon d'inclinaison.
(KO) 본 발명의 실시예에 따른 전동식 파워 스티어링 시스템은 내측에 수용공간을 형성하는 하우징, 상기 수용공간에 배치되어 웜휠과 치합되는 웜샤프트, 상기 하우징의 내면에 결합되어 미리 설정된 위치에 고정되고, 상기 수용공간으로 삽입되는 상기 웜샤프트와 결합되어 상기 웜샤프트를 지지하는 틸트 플러그, 그리고 상기 하우징에 설치되어 상기 틸트 플러그를 상기 웜휠 측으로 탄성 지지하는 탄성지지부를 포함하고, 상기 틸트 플러그에는 상기 틸트 플러그의 단부로부터 상기 틸트 플러그의 중심축 방향으로 돌출되어 상기 하우징의 내면에 슬라이딩 삽입되는 결합돌기가 형성되고, 상기 하우징의 내면에는 상기 결합돌기가 슬라이딩 삽입 가능한 결합홈이 형성되어, 상기 틸트 플러그의 회전을 제한한다.
