The invention relates to an electric drive axle and an electric truck. The electric drive axle is provided with a main drive motor, an auxiliary drive motor, a speed reducer assembly and a differential mechanism assembly, and is characterized in that the speed reducer assembly is provided with a main drive first-stage speed reduction stage, an auxiliary drive first-stage speed reduction stage, a first-gear transmission mechanism, a second-gear transmission mechanism and a gear shifting mechanism, and the gear shifting mechanism achieves switching of the first gear, the second gear and a neutral gear; the main drive motor transmits power to the differential mechanism assembly through the main drive first-stage speed reduction stage and the first-gear transmission mechanism or the second-gear transmission mechanism, the speed reducer assembly is further provided with an auxiliary drive force disengaging device, and the auxiliary drive motor can transmit power to the first-gear transmission mechanism through the auxiliary drive first-stage speed reduction stage and coupling of the auxiliary drive force disengaging device. And passive idling is avoided through disconnection of the auxiliary driving force disengaging device. The electric truck according to the invention has an electrically driven axle.
本发明涉及电驱桥和电动卡车。电驱桥具有主驱电机、辅驱电机、减速器总成和差速器总成,其特征在于,减速器总成具有主驱一级减速级、辅驱一级减速级、一挡传动机构、二挡传动机构和换挡机构,其中换挡机构实现一挡、二挡和空挡的切换,其中,主驱电机经由主驱一级减速级、通过一挡传动机构或二挡传动机构将动力传递至差速器总成,其中减速器总成还具有辅驱动力脱开装置,辅驱电机能够经由辅驱一级减速级、通过辅驱动力脱开装置的耦合将动力传递至一挡传动机构,并且通过辅驱动力脱开装置的断开避免被动空转。按照本发明的电动卡车具有电驱桥。
