The invention discloses an electric automobile and a double-motor coaxial electric automobile drive axle thereof, and the drive axle comprises a left motor, a planetary gear differential mechanism, a right motor, a right half shaft and a left half shaft; the planetary gear differential mechanism comprises a right-row sun gear, a right-row planetary gear, a left-row sun gear, a left-row planetary gear and a differential planet carrier; the right-row sun gear is meshed with the right-row planetary gear, the left-row sun gear is meshed with the left-row planetary gear, the left-row planetary gear is meshed with the right-row planetary gear, and the right-row planetary gear and the left-row planetary gear are installed on the differential planet carrier. The left motor shaft and the right motor shaft are respectively in transmission fit with the differential planet carrier; one end of the right half shaft is fixedly connected with the right-row sun gear; and one end of the left half shaft is fixedly connected with the left-row sun gear. According to the design of the scheme, a single motor or double motors can be selected for driving according to the running working condition of a vehicle, the effect of a small structural envelope surface is achieved, the overall structure of the drive axle is made to be smaller, and meanwhile the energy consumption performance is improved.
Description
technical field [0001] The invention relates to the technical field of electric vehicle drive, in particular to an electric vehicle and a dual-motor coaxial electric vehicle drive axle thereof. Background technique [0002] An electric vehicle refers to a vehicle powered by a vehicle-mounted power supply, driven by a motor to drive the wheels, and conforming to the requirements of road traffic and safety regulations. Generally, the powertrain of an electric vehicle is composed of a drive motor directly connected to a single-speed ratio reducer. The drive motor and the reducer are manufactured separately, then assembled, and installed on the chassis of the electric vehicle. [0003] However, due to the large overall structure of the drive motor and the reducer, most of the space in the vehicle chassis is occupied, making the powertrain structure of the vehicle appear bloated. Contents of the invention [0004] In view of this, the embodiment of the present invention provid...
