摘　　要：随着汽车行业的不断创新发展,发动机新技术不断的应用、各种测油耗APP的使用,消费者对乘用车的油耗及加速性能都极为关注,也开始对车辆的舒适性、整体NVH性能、油耗要求不断提高。新技术BSG系统,替代传统的发电机及起动机,有启动、助力、能量回收、发电等4个功能,从而提高车辆的动力性、经济性及NVH性能。由于BSG系统工况复杂,并且采用楔型皮带进行驱动,BSG电机在工况切换时会使得皮带的松紧边进行切换,通常会使用双向BSG张紧器进行张紧。针对某车型BSG轮系皮带脱落问题,对皮带脱落的产生机理及影响因素进行分析,通过对轮系系统的优化,结合耐久试验,研究了BSG轮系驱动皮带在光轮两端的长短调整对轮系的影响及改善效果。最终通过优化轮系布局解决了皮带脱落问题。With the continuous innovation and development of the automobile industry,the continuous application of new engine technology,and the use of various fuel consumption apps,customers are extremely concerned about the fuel consumption and acceleration performance of passenger cars,and have begun to improve the comfort of vehicles,the overall NVH performance and fuel consumption requirements.New technology BSG system,replacing the traditional generator and starter,has four functions such as starting,assisting,energy recovery,and power generation,so as to improve the vehicle′s power,economy and NVH performance.Due to the complex working conditions of the BSG system and the wedge-shaped belt is used to drive the BSG motor,the elastic edge of the belt will be switched when the working conditions are switched,and the bidirectional BSG tensioner is usually used for tensioning.Aiming at the problem of BSG wheel belt shedding of a certain model,the mechanism and influencing factors of belt shedding are analyzed.Through the optimization of the wheel system,combined with the durability test,the effect of adjusting the length of BSG driving belt at both ends of the light wheel on the gear train and the improvement effect are studied.Finally,the belt shedding problem was solved by optimizing the wheel train layout.
