自动变速器拖曳扭矩变化趋势浅析

Elementary Analysis upon Variation Tendency of Automatic Transmission Drag Torque

文章以某6速湿式双离合变速器作为蓝本,通过单一变量法,调节变速箱不同输入参数,测试得到不同工况下的变速箱拖曳扭矩值,分析探究变速箱拖曳扭矩随不同参数的变化趋势,为自动变速箱的效率研究、整车中变速箱工作点的自动控制调节等,提供参考和依据。

This article bases on a 6 gears wet-type dual-clutch transmission, with single variable method, setting different parameters as variables, get series of transmission drag torques via tests, then give out the drag torque variation tendency with different parameters, which would be quite useful in further transmission efficiency study, and work condition setting of automatic transmission in vehicles.
