重型商用车变速换挡性能提升探讨

Heavy Commercial Vehicle Transmission Shift Performance Discussion

手动机械变速器重卡在使用时换挡频繁,变速换挡性能的好坏直接影响驾驶员对车辆的评价。针对某款搭载6挡手动机械变速器载货车换挡性能差的问题,结合变速操纵系统结构,利用故障树分析法对发生故障的原因进行多层次分析,对故障原因制定控制方案及整改提升,通过试验验证对系统的性能进行评价,以提高整车的操控方便性和操纵轻便性。

Automobile with manual transmission shift frequently when used,shifting performance will have adirect impact on driver’s evaluation for vehicle.For models equipped with a six-speed manual mechanicaltransmission trucks shifting performance poor problems,combined with variable speed control systemarchitecture,use FTA method to analyze the reasons of the generation,for the cause of the fault rectification andexperimental verification.Through experimental verification evaluating performance of system,to increasingoperation convenience and manage lightly of vehicle.
