Electric drive axle and electric truck

Abstract

An electric drive axle for electric trucks, wherein the electric drive axle comprises a main drive motor, a transmission assembly, and a differential assembly, the transmission assembly comprising a primary reduction stage, a first-gear transmission mechanism, a second-gear transmission mechanism, a third-gear transmission mechanism, a first shifting mechanism, and a second shifting mechanism, wherein the primary reduction stage consists of a primary reduction drive gear and a primary reduction output gear meshing with each other, the primary reduction drive gear being fixedly mounted on the motor shaft, characterized in that the first-gear transmission mechanism consists of a planetary gear set, a first drive gear, and a first output gear, and the second-gear transmission mechanism consists of the planet carrier of the planetary gear set.the first drive gear and the first output gear, and the third-gear transmission mechanism consists of a second drive gear and a second output gear, wherein the torque of the main drive motor is transmitted via the primary reduction stage through the first-gear transmission mechanism or the second-gear transmission mechanism or the third-gear transmission mechanism to the differential assembly.
