Title (EN) POWER STEERING DEVICE AND POWER STEERING DEVICE MANUFACTURING METHOD
(FR) DISPOSITIF DE DIRECTION ASSISTÉE ET PROCÉDÉ DE FABRICATION DE DISPOSITIF DE DIRECTION ASSISTÉE
(JA) パワーステアリング装置およびパワーステアリング装置の製造方法
Abstract:
(EN) Provided are a power steering device capable of improving concentricity between a nut and an output pulley and a power steering device manufacturing method. The power steering device comprises an output pulley 9 having a cylindrical part 17 surrounding a nut 8 and a radial direction space between the nut 8 and the output pulley 9 in a radial direction about an axis of rotation O1 of the nut 8; and a bolt 10 provided between the nut 8 and the output pulley 9 that fixes the relative position of the nut 8 and the output pulley 9 such that the radial direction space exists between the nut 8 and the output pulley 9 over the entire circumference around the axis of rotation O1.
(FR) L'invention concerne un dispositif de direction assistée apte à améliorer la concentricité entre un écrou et une poulie de sortie, ainsi qu'un procédé de fabrication de dispositif de direction assistée. Le dispositif de direction assistée comprend une poulie de sortie (9) ayant une partie cylindrique (17) entourant un écrou (8) et un espace dans la direction radiale entre l'écrou (8) et la poulie de sortie (9) dans une direction radiale autour d'un axe de rotation (O1) de l'écrou (8) ; et un boulon (10) prévu entre l'écrou (8) et la poulie de sortie (9) qui fixe la position relative de l'écrou (8) et de la poulie de sortie (9), de sorte que l'espace dans la direction radiale existe entre l'écrou (8) et la poulie de sortie (9) sur toute la circonférence autour de l'axe de rotation (O1).
(JA) ナットと出力プーリとの同軸性を向上できるパワーステアリング装置およびパワーステアリング装置の製造方法を提供する。ナット8を包囲する筒状部17を有しナット8の回転軸O1に対する径方向においてナット8との間に径方向隙間を有する出力プーリ9と、ナット8と出力プーリ9との間に設けられ回転軸O1周りの方向全周に亘ってナット8と出力プーリ9との間に径方向隙間ができるようにナット8と出力プーリ9との相対位置を固定するボルト10と、を有する。
