现有分布式驱动电动汽车的轮边驱/传动系统簧下质量笨重、系统成本过高,成为制约其技术进步和推广应用的主要瓶颈。本文通过对轮边电机、同步带传动装置与单摆臂悬架一体化机构的结构设计与分析,提出了有效减小轮边驱/传动系统垂向振动负效应的机构原理,并进行了单摆臂悬架系统运动学仿真,验证了轮边电驱动系统质心位置对汽车平顺性有较大影响。
The wheel hub drive / transmission system of the existing distributed drive electric vehicles is bulky and the system cost is too high, which becomes a major bottleneck that restricts its technological progress and popularization and application. Based on the structure design and analysis of the integrated mechanism of the wheel rim motor, timing belt transmission and single swing arm suspension, this paper proposed the mechanism principle of reducing the negative effect of vertical vibration of the wheel rim drive / transmission system effectively, The kinematics simulation of the swing arm suspension system verifies that the center of mass of the wheel drive electric drive system has a great influence on the ride comfort of the automobile.
