摘要
电动公交传动系统布置方式直接影响着整车的动力性和经济性,同时对电机的参数选择有较大的影响。采用多档传动系统可以提高电动公交车性能,降低对电机的要求,延长续驶里程。根据Cruise的仿真要求,建立了纯电动公交车的整车、电机、离合器、变速器、车轮和驾驶室的数学模型。对“电机+离合器+五挡AMT”的传动系统进行了动力性和经济性的仿真,并与“电机直驱”和“电机+两挡变速器”的传动系统动力性和经济性进行了对比。对比表明“电机+离合器+五挡AMT”方案明显优于其他方案。
The power train matching of the electric bus directly affects its drivability and economy.Moreover,it has some influence on the motor parameter matching.Multi-speed transmission system can be used to improve the performance of the electric bus and lower the requirement of motor performance and extend the diving range.According to the simulation requirements of Cruise,the mathematical models are established,including vehicle model,motor model,clutch model,transmission model,wheel model recockpit model.The drivability and economy of“Motor and Clutch and Five-speed AMT”transmission system are calculated,which are compared to the“Motor Direct Drive”and“Motor and Two-speed Transmission”system.
