Abstract: front page image
(EN)This air spring is capable of adjusting the spacing between stoppers with ease and in a reliable manner. Specifically, an upper member (3) and a lower member (4) are secured to upper and lower ends of a bellows (2). The upper member (3) and the lower member (4) have formed thereon stopper surfaces (5), (6) that come into contact with each other and restrict the amount of displacement of the upper member (3). The lower member (4) is provided with a movable body (7) capable of moving up and down and adjusting the height of the stopper surface (6). There is provided a holding body (8) for holding the movable body (7) while allowing the movable body to move up and down. The movable body (7) is capable of rotating, relative to the holding body (8), about a center axis (18). Tapers (32), (41) are formed on the movable body (7) and/or the holding body (8) so as to be capable of sliding against the holding body and/or the movable body. The movable body (7) is caused to rotate relative to the holding body (8), the tapers (32), (41) are caused to slide, and the movable body (7) is moved up and down.
(FR)La présente invention concerne un ressort pneumatique qui est capable de régler l'écart entre butoirs facilement et de manière fiable. Précisément, un élément supérieur (3) et un élément inférieur (4) sont solidement fixés aux extrémités supérieure et inférieure d'un soufflet (2). Sur l'élément supérieur (3) et l'élément inférieur (4) sont formées des surfaces (5, 6) de butoir qui entrent en contact l'une avec l'autre et limitent la quantité de déplacement de l'élément supérieur (3). L'élément inférieur (4) est pourvu d'un corps mobile (7) capable de monter et descendre et de régler la hauteur de la surface (6) de butoir. L'invention comporte un corps de maintien (8) pour tenir le corps mobile (7) tout en permettant à celui-ci de monter et descendre. Le corps mobile (7) est capable de tourner par rapport au corps de maintien (8) autour d'un axe central (18). Des pentes (32, 41) sont réalisées sur le corps mobile (7) et/ou le corps de maintien (8) de façon à pouvoir coulisser contre le corps de maintien et/ou le corps mobile. On fait tourner le corps mobile (7) par rapport au corps de maintien (8), les pentes (32, 41) sont amenées à coulisser et le corps mobile (7) monte et descend.
