汽车变速箱用铜基粉末冶金单/双锥同步环

汽车变速箱中同步器是最重要的部件之一。随着汽车使用的马力不断增加 ,离合器和变速箱的扭矩相应增加 ,零件的尺寸也相应增大。同时 ,人们又要求换挡更轻盈、更舒适 ,并且尺寸要更小。一种同步性能更高、换挡力更小、承载能力更强的同步器 -多锥同步器愈来愈引起汽车制造商的重视。被烧结在单 /双锥同步环锥芯上的一种新型高效的铜基粉末冶金摩擦材料 -铜基粉末冶金单 /双锥同步环 ,为提高同步器的性能起到了决定性的作用。本文介绍了德国贺尔碧格公司将与杭州粉末冶金研究所合资生产的贺尔碧格专利产品 -铜基粉末冶金单/双锥同步环的特性及工艺流程 ;并与黄铜同步环、钼同步环、纸基同步环的特性进行了分析对比 ;推荐采用贺尔碧格多锥同步器的设计技术来改进同步器的设计

COPPER-BASE P/M DOUBLE-CONE SYNCHRONIZING RING

The synchronizer is one of the most important parts for automobile transmission With the increase of horsepower of automobiles,the torque is increased as well as the dimensions But comfortability and smooth driving are still required Thus the synchronizer with better performance,double-cone synchronizer-is drawing more and more attention of automobile manufacturers.The copper base P/M double-cone synchronizing ring,is the key part of such synchronizer.The features and process of Hoerbiger patented copper base P/M double-cone synchronizing ring to be produced by the joint venture of Hoerbiger Antriebsechnik Gmbh,Germany and Hangzhou P/M Research Institute are introduced. The characteristics of the brass synchronizing ring,molybdenum-based steel synchronizing ring and paper base synchronizing ring,are analysed and compared with.
