埃利果(ELIGO)是由金属螺旋弹簧和橡胶组成的弹簧名称,在意大利的SAGA公司已经商品化,在日本由东海橡胶公司制造。埃利果弹簧的构造如图1所示,它由螺旋弹簧和卷绕成螺旋状的橡胶组成。螺旋弹簧承受埃利果弹簧的一部分(或大部分)载荷,并可防止弹簧变形时的走形及橡胶的横向异形突出。而橡胶则在承受反复形变的同时承受部分载荷,另外,由于橡胶的内部摩擦,还能起减振作用。埃利果弹簧正是利用了橡胶的优良性质,具有金属弹簧所没有的许多特征,因此,各国铁道车辆的轴箱弹
ELIGO is a spring name made up of a metal coil spring and a rubber, which has been commercialized by SAGA in Italy and made by Tokai Rubber Co. in Japan. The structure of the Eliot spring is shown in Fig. 1, which consists of a coil spring and a spiral wound rubber. Helical springs bear some (or most) of the load of the Elgeberry spring and prevent the springs from deforming and the transverse profile of the rubber from protruding. The rubber is subjected to repeated deformation while bearing part of the load, in addition, due to the internal friction of rubber, but also play a damping effect. The Eliot spring is the use of the excellent properties of rubber, with many of the characteristics of the metal spring does not, therefore, the national railway vehicles axlebox
