Abstract

The invention provides an electric drive axle decelerating after output of coaxial dual motors. In a shifting process of an electric automobile, power of the whole automobile cannot be interrupted, and comfort and safety of automobile traveling are ensured. The electric drive axle comprises a differential mechanism, a first wheel and a second wheel, wherein the first wheel and the second wheel are respectively arranged on two sides of the differential mechanism; two output sides of the differential mechanism are connected with the first wheel and the second wheel through half shafts; the differential mechanism comprises a main reduction gear; a first motor and a second motor correspondingly sleeve the two half shafts respectively; a first motor shaft of the first motor and a second motor shaft of the second motor are hollow shafts; the corresponding half shafts respectively penetrate in the center of the first motor shaft and the center of the second motor shaft; two input gears are fixedly mounted at a corresponding output end, which is close to the differential mechanism, of each motor shaft, the corresponding positions of each two input gears are respectively connected with two corresponding output gears in an engaged manner, and each two output gears are fixedly mounted on the same output shaft.

Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to an electric drive drive axle with coaxial double motor output and deceleration. Background technique [0002] With the rapid development of my country's economic construction and the continuous improvement of people's living standards, the number of automobiles in our country is also increasing, which brings huge pressure on our resources and environment. As an important chemical raw material - petroleum, more than half of it is used as fuel for motor vehicles. Therefore, the development of energy-saving vehicles and the use of alternative energy sources are the main ways to alleviate the current energy pressure. [0003] The use of pure electric energy as new energy vehicles has become the mainstream trend. However, the existing electric vehicles are only provided with a power motor. When the output end of the power motor is connected to a shifting structure, the ele...
