国内同步器齿环与国外同步器齿环主要的质量差别是产品的耐磨性不够 .国外同类产品耐磨性好 ,但其价格昂贵 ,而且国内轿车生产厂家容易受国外同步器齿环厂家的控制 .研制自己独立技术的新型同步器齿环用功能材料 ,突破外国的技术封锁 ,并利用国内的人力资源和原材料价格低的优? The main quality difference between domestic synchronizer gear ring and foreign synchronizer gear ring is that the wear resistance of the product is not enough.The wear resistance of the foreign similar products is good but its price is expensive and the domestic car manufacturers are easily influenced by the foreign synchronizer gear ring manufacturers Controlling the development of a new type of synchronizer toothed ring with its own independent technology, breaking through foreign technology blockades and utilizing domestic human resources and low prices of raw materials.
