The invention provides an electric drive axle which comprises a plurality of motors, two output half shafts connected through a differential mechanism and a center shaft, a first transmission mechanism is arranged between each motor and the center shaft, and a second transmission mechanism and a third transmission mechanism are arranged between the center shaft and the differential mechanism. Each first transmission mechanism is provided with a first intermediate shaft, a first gear shifting device, a first gear transmission unit and a second gear transmission unit; the second transmission mechanism is provided with a second gear shifting device, and a third gear transmission unit and a fourth gear transmission unit which have different transmission ratios are arranged between the second gear shifting device and the differential mechanism. The third transmission mechanism is provided with a third gear shifting device arranged on the center shaft in a sleeving mode, and the center shaft can be in direct transmission connection with the differential mechanism through connection of the third gear shifting device. According to the electric drive axle, gears can be conveniently adjusted, different torques can be output, and the reliability of the electric drive axle in use can be improved.
本发明提供了一种电驱动桥,包括多个电机,由差速器相连的两个输出半轴,以及中心轴,各电机与中心轴之间分别设有第一传动机构,中心轴与差速器之间设有第二传动机构和第三传动机构;各第一传动机构均具有第一中间轴,第一换挡装置,以及第一齿轮传动单元和第二齿轮传动单元;第二传动机构具有第二换挡装置,并在第二换挡装置和差速器之间设有具有不同传动比的第三齿轮传动单元和第四齿轮传动单元;第三传动机构具有套设在中心轴上的第三换挡装置,且中心轴能够通过第三换挡装置的接合与差速器直接传动相连。本发明所述的电驱动桥,便于对挡位进行调节,而输出不同扭矩,还利于提高电驱动桥在使用中的可靠性。
