双离合变速器车辆的故障成因与防范策略

The Cause and Prevention Strategy of Dual Clutch Transmission Vehicle

搭载双离合变速器的车辆能够实现"无缝换挡,动力无中断",具有良好的舒适性和燃油经济性,深得车主的喜爱。而这种特殊的结构设计也被广泛应用于中高端车上。但是,当这种结构设计投放市场后,却出现了前所未有的问题——"突然丧失动力""跛脚现象"等。分析双离合器结构和控制原理,探索故障发生的规律,并提出合理用车的建议,减少车辆故障的发生,延长车辆的使用寿命。

The vehicle equipped with dual clutch transmission can achieve seamless shift, power without interruption, with good comfort and fuel economy, the owners of the deep love. And this special structure design is also widely used in the high-end car. But when the structure design of the market, there was an. unprecedented problems - ＂all of a sudden loss of power＂ ＂lame＂. In this paper, the structure and control principle of dual clutch is analyzed, and the law of failure occurrence is explored, and the suggestion of rational use of the car is put forward, which is to reduce the occurrence of vehicle failure and prolon~ the service life of the vehicle.
