The invention relates to a two-speed pure electric sanitation vehicle power system and a pure electric sanitation vehicle. The power system comprises an operation mechanism, a system output shaft, a driving motor and a gear shifting mechanism, wherein the first power output end of the driving motor is connected with the operation mechanism through a first clutch, and the second power output end ofthe driving motor is connected with the gear shifting mechanism through a second clutch. The gear shifting mechanism can realize a two-speed switching function; gear shifting is conducted according to the actual torque requirement of a vehicle such that required torque output is achieved; different torque outputs can be achieved only through one driving motor and one gear shifting mechanism suchthat the input cost is reduced, the system weight is reduced, the arrangement space is increased, it is guaranteed that the driving motor always works in an efficient area, and the motor operation efficiency is improved. Besides, the whole gear shifting mechanism can be completely disconnected from the driving motor by controlling the second clutch to be separated, the gear shifting mechanism doesnot consume energy, the overall energy consumption is greatly reduced, and the system operation efficiency is improved.
本发明涉及一种两挡纯电动环卫车动力系统及一种纯电动环卫车,该动力系统包括作业机构、系统输出轴、驱动电机和换挡机构,驱动电机的第一动力输出端通过第一离合器连接作业机构,驱动电机的第二动力输出端通过第二离合器连接换挡机构。换挡机构能够实现两挡切换的功能,根据车辆实际扭矩需求切换挡位,实现所需扭矩输出,而且只通过一个驱动电机和换挡机构就可以实现不同扭矩输出,降低了投入成本,减轻了系统重量,增大了布置空间,保证了驱动电机始终工作在高效区,提升电机运行效率。另外,控制第二离合器分离能够使整个换挡机构完全与驱动电机断开,换挡机构不消耗能量,整体的能量消耗大幅度降低,提升系统运行效率。
