Analysis and Optimization of Differential Mechanism Damage for an Electric Bus
HAN Xuewen,WANG Gongbo,LIU Yueqing,LI Fei,HAN Jinzhi
Abstract: During the test, it is found that when a pure electric bus rapidly accelerated on the high and low attachment road surfaces, the rear axle differential mechanism failed. This paper finds the failure causes and solves the above problems by adding the differential protection function. Finally, the optimization scheme is verified through the real vehicle.
Key words: electric bus; differential mechanism; differential protection
