汽车传动系的优化设计

The optimizing design of the Automotive Drive line

影响汽车动力性和燃油经济性的因素很多，如何进行匹配与选择是目前各汽车生产厂家所面对的问题。也是当前所研究的热门课题。文中主要从变速器的速比和后桥主减速比的匹配通过理论与试验相结合的方法来对一款商务车的传动系优化设计，期望使整车的动力性和经济性匹配最好。

There are many factors, which influence the automotive mobility and the fuel consumption economy. How to match and choose in a accurate way is the hot topic for all the automotive manufacturers and the hot topic nowadays. This paper presents the main idea of matching the transmission gear ratio with the rear axle final gear ratio, taking the combination way of the theory and the experiments to optimize the drive line design of the commercial vehicle. Looking forward to getting a best matching way of the mobility and the economy for the complete vehicle.
