(JA) 軸受およびステアリング機構
Abstract:
(EN) Provided is a bearing suitable for a rack bush with which an impact on the feeling of a steering operation can be reduced. A rack bush (1) is accommodated inside a cylindrical housing (4) to support a load applied to a rack bar (5) while permitting movement in the direction of an axis O of the rack bar (5), and is provided with a bush main body (2) capable of expanding and contracting in a radial direction, and a resilient ring (3) fitted onto the bush main body (2). The bush main body (2) has a plurality of first and second slits (25, 26) formed in the direction of the axis O from end surfaces (23, 24) thereof. The first and second slits 25, 26 are arranged offset from one another in the circumferential direction of the bush main body 2, and form in the bush main body (2) a slit arranged region (280) in which the first and second slits (25, 26) are arranged, and a slit non-arranged region (281) in which the first and second slits (25, 26) are not arranged.
(FR) L'invention concerne un palier approprié pour un coussinet de crémaillère avec lequel un impact sur la sensation d'une opération de direction peut être réduit. Un coussinet (1) de crémaillère est logé à l'intérieur d'un boîtier cylindrique (4) pour supporter une charge appliquée à une barre (5) de crémaillère tout en permettant un mouvement dans la direction d'un axe O de la barre (5) de crémaillère, et est pourvu d'un corps principal (2) de coussinet susceptible de se dilater et de se contracter dans une direction radiale, et d'un anneau élastique (3) ajusté sur le corps principal (2) de coussinet. Le corps principal (2) de coussinet a une pluralité de première et seconde fentes (25, 26) formées dans la direction de l'axe O à partir de surfaces d'extrémité (23, 24) de celui-ci. Les première et seconde fentes 25, 26 sont disposées de manière décalée l'une par rapport à l'autre dans la direction circonférentielle du corps principal (2) de coussinet, et forment dans le corps principal (2) de coussinet une région (280) d'agencement de fentes dans laquelle sont agencées les première et seconde fentes (25, 26), et une région (281) de non-agencement de fentes dans laquelle les première et seconde fentes (25, 26) ne sont pas agencées.
(JA) ステアリング操作のフィーリングに与える影響を低減することができるラックブッシュに好適な軸受を提供する。ラックブッシュ(1)は、円筒状のハウジング(4)内に収容され、ラックバー(5)の軸心O方向の移動を許容しつつ、ラックバー(5)に加わる荷重を支持するものであり、径方向に伸縮自在なブッシュ本体(2)と、ブッシュ本体(2)に装着された弾性リング(3)と、を備えている。ブッシュ本体(2)は、端面(23、24)から軸心O方向に沿って形成された複数の第一、第二スリット(25、26)を有する。第一、第二スリット25、26は、ブッシュ本体2の円周方向に偏向配置されて、ブッシュ本体(2)に、第一、第二スリット(25、26)が配置されているスリット配置領域(280)と、第一、第二スリット(25、26)が配置されていないスリット無配置領域(281)と、を形成している。
