Abstract
(EN)
The present invention addresses the problem of further reducing the overall height and at the same time ensuring preferable spring property at the time of deflation in an air spring for a vehicle using both an external stopper and an internal stopper each having spring property. Disclosed is an air spring for a vehicle, wherein an internal stopper (6) is provided inside a diaphragm (4) and a concave portion (8) formed on an inner tube (3) is placed inside an external stopper (5) to overlap the external stopper (5) in the height direction by the length (L). In an embodiment, the concave portion (8) is provided with an inverted conical peripheral wall (8-1) and a bottom wall (8-2), a pressing plate (7) is provided with an inverted conical load application surface (9a) in a vertically suspended manner, an inverted conical semi-shear stopper is provided as the internal stopper (6), and an inside diameter surface (fi) and an outside diameter surface (fo) of the semi-shear internal stopper (6) are fixed on the load application surface (9a) and on an inner surface of the peripheral wall (8-1), respectively.

La présente invention aborde le problème de réduire davantage la hauteur totale et garantir en même temps une propriété de ressort préférable au moment du dégonflage d'un ressort pneumatique pour un véhicule à la fois à l'aide d'une butée externe et d'une butée interne ayant chacune une propriété de ressort. L'invention porte sur un ressort pneumatique pour un véhicule, dans lequel une butée interne (6) est disposée à l'intérieur d'un diaphragme (4) et une partie concave (8) formée sur un tube interne (3) est placée à l'intérieur d'une butée externe (5) pour chevaucher la butée externe (5) dans la direction de la hauteur par la longueur (L). Dans un mode de réalisation, la partie concave (8) comporte une paroi périphérique conique inversée (8-1) et une paroi inférieure (8-2), une plaque de compression (7) est munie d'une surface d'application de charge conique inversée (9a) d'une manière suspendue verticalement, une butée de semi-cisaillement conique inversée est prévue en tant que butée interne (6), et une surface de diamètre interne (fi) et une surface de diamètre externe (fo) de la butée interne de demi-cisaillement (6) sont fixées sur la surface d'application de charge (9a) et sur une surface interne de la paroi périphérique (8-1), respectivement.

 各々がばね性を有する外部ストッパと内部ストッパを併用した車両用空気ばねについて、全高の更なる低下と、デフレート時の良好なばね特性の確保を両立させることを課題としている。ダイヤフラム(4)の内側に内部ストッパ(6)を設け、内筒(3)に形成した凹部(8)を外部ストッパ(5)の内側に入り込ませて外部ストッパ(5)に対して高さ方向に長さLオーバラップさせた車両用空気ばねであって、一実施態様において、前記凹部(8)に下細り円錐形の周壁(8-1)と底壁(8-2)を備えさせ、押圧板(7)には、下細り円錐形の荷重印加面(9a)を垂下させて設け、さらに、前記内部ストッパ(6)として、下細り円錐形の準剪断型のストッパを設け、この準剪断型の内部ストッパ(6)の内径面(fi)を荷重印加面(9a)に、外径面(fo)を前記周壁(8-1)の内面にそれぞれ固定した。
