The invention relates to a sanitation vehicle electric drive axle which comprises a drive motor, a first-stage driven gear is pushed through a stepping motor and a shifting fork, the first-stage driven gear is selectively connected with a second-stage driving gear and/or a drive gear oil pump for transmission, and three power output modes are achieved. A motor does not need to be independently adopted to provide auxiliary power or a reduction gearbox with a neutral position is matched with a power takeoff to output power, the arrangement space is saved, the weight of the whole vehicle is reduced, the cost is reduced, meanwhile, the integration level is improved, the transmission efficiency is improved, and more endurance mileage can be obtained; according to the use conditions of the pure electric sanitation vehicle such as a motor sweeper, a wrecker and a garbage truck, when power is needed for operation in the running and parking states, the main motor can be used for providing power, and the operation power requirement is met.
本发明涉及一种环卫车电驱动桥,该驱动桥,包括驱动电机,第一级从动齿轮通过步进电机及拨叉移推动,与第二级主动齿轮和或驱动齿轮油泵选择性连接传动,实现三种动力输出模式。本发明不用单独采用电机提供辅助动力或带空档减速箱配取力器输出动力,节省布置空间,减轻整车重量,降低成本,同时提高了集成度,提高传动效率,得以获得更多的续航里程;根据纯电动环卫车如清扫车、清障车、垃圾清运车等的使用工况,在行驶及停车状态下需要动力进行作业时,利用主电机可提供动力,满足作业动力需求。
