The invention relates to an electric axle for a motor vehicle. The electric axle comprises a speed reducer including an input shaft. The speed reducer is configured to receive a drive torque from theinput shaft and output the drive torque to a wheel after the drive torque is increased and comprises a first planetary transmission device and a second planetary transmission device. The first planetary transmission device comprises a first sun gear, a first planet gear and a first planet carrier; the second planetary transmission device comprises a second sun gear, a second planet gear and a second planet carrier; and the first planet carrier is in transmission connection with the second sun gear, so that the first planetary transmission device is in transmission connection with the second planetary transmission device, and the second planet carrier is in transmission connection with a hub of a wheel. The drive torque is input to the first sun gear from the input shaft, transmitted to thesecond sun gear through the first planet gear and the first planet carrier in sequence, and output to wheels through the second planet gear and the second planet carrier.

    本发明涉及一种用于机动车的电动车桥,包括:减速器,其包括输入轴并且被构造为从输入轴接收驱动转矩以及使驱动转矩增大后输出到车轮;所述减速器包括第一行星传动装置和第二行星传动装置,所述第一行星传动装置包括第一太阳轮、第一行星轮和第一行星架,所述第二行星传动装置包括第二太阳轮、第二行星轮和第二行星架,所述第一行星架和所述第二太阳轮传动连接,从而使得第一行星传动装置和第二行星传动装置传动连接,并且,所述第二行星架和车轮的轮毂传动连接;其中,驱动转矩从所述输入轴输入到所述第一太阳轮、依次经由所述第一行星轮和所述第一行星架传递到所述第二太阳轮、并且再经由所述第二行星轮和所述第二行星架输出到车轮。
