由于发动机功率的提高和变速器结构的小型化,使变速器同步环的负荷增大了。西德金属联合公司研究所与金属协会金属试验室共同进行的变速器同步环材料的研究,其目的是研制出一种新的材料。这种材料不仅具有目前使用材料的摩擦性能,而且还有较高的抗磨性。一、前言长期以来,小轿车机械式变速器同步环使用的材料,一直是牌号为CuZn40Al2(DIN
Due to the increased engine power and the miniaturization of the transmission structure, the load on the synchronizing ring of the transmission is increased. Synchrotron materials research was carried out jointly by the Institute of Metal and Metal Research and Metals Laboratory of the Metal Association, with the aim of developing a new material. This material not only has the friction properties of currently used materials, but also has high abrasion resistance. I. Foreword For a long time, the material used by the synchro ring of the mechanical transmission of a car has been the grade of CuZn40Al2 (DIN
