Title
(EN) ELECTROMAGNETIC SHOCK ABSORBER FOR VEHICLE
(FR) AMORTISSEUR DE CHOC ÉLECTROMAGNÉTIQUE POUR VÉHICULE
Abstract
(EN)
An electromagnetic absorber (10) for a vehicle including (a) a threaded rod (78) which is disposed on one of a sprung portion and an unsprung portion and which has a threaded groove (76) formed in its outer circumferential portion and an axial groove (90) extending in its axis direction (b) a nut (80) which is rotatably disposed on the other of the sprung portion and the unsprung portion and which is screwed with the threaded rod and (c) a rod-rotation inhibiting member (82) which includes a fitting portion configured to be fitted in the axial groove and which is disposed on the other of the sprung portion and the unsprung portion, the rod-rotation inhibiting member being configured to inhibit the threaded rod from rotating while permitting the threaded rod to move in the axis direction. In the electromagnetic absorber, the threaded groove is not formed at a section of a fitting range at which the fitting portion is fitted in the axial groove when the fitting portion is located at an end of the fitting range that extends in the axis direction on the outer circumferential portion of the threaded rod.
(FR)
L'invention concerne un amortisseur électromagnétique (10) pour un véhicule, comprenant (a) une tige filetée (78) qui est disposée sur l'une d'une partie suspendue et d'une partie non suspendue et qui a une rainure filetée (76) formée dans sa partie périphérique externe et une rainure axiale (90) s'étendant dans sa direction axiale, (b) un écrou (80) qui est disposé en rotation sur l'autre de la partie suspendue et de la partie non suspendue et qui est vissé avec la tige filetée et (c) un élément d'interdiction de rotation de tige (82) qui comprend une partie d'adaptation configurée pour être adaptée dans la rainure axiale et qui est disposé sur l'autre de la partie suspendue et de la partie non suspendue, l'élément d'interdiction de rotation de tige étant configuré pour empêcher la tige filetée de tourner tout en permettant à la tige filetée de se déplacer dans la direction axiale. Dans l'amortisseur électromagnétique, la rainure filetée n'est pas formée à une section d'une plage d'adaptation à laquelle la partie d'adaptation est adaptée dans la rainure axiale lorsque la partie d'adaptation est située à une extrémité de la plage d'adaptation qui s'étend dans la direction axiale sur la partie périphérique externe de la tige filetée.
