[0002] In recent years, due to the rapid development of electric vehicles and electric tricycles due to their environmental protection performance and low usage fees, the manufacture and demand for the rear axle of electric vehicles have shown a rapid development trend. The rear axle on electric vehicles generally uses a motor to drive the reducer to connect to the differential The motor drives the two semi-shafts on the rear axle to rotate. This kind of rear axle is equipped with a motor, which can basically meet the requirements for the use of small power and low torque, but cannot fully meet the requirements for the use of high power and high torque. Requirements, on the other hand, the motor is easily damaged when the transmitted torque and power are too large. In recent years, electric vehicles have been used more and more widely for cargo purposes. Relying on increasing the power of the motor cannot fully meet the needs of the development of electric vehicles, and the excessively large volume of the motor will also cause space problems for the installation of the rear axle. In the current market, there is a need for a motor that can adjust the output torque and power according to needs. electric car rear axle

Embodiment Construction
[0008] In order to better understand and implement the technical solutions of the present invention, some embodiments of the present invention are provided here. These examples are for better explaining the technical solutions of the present invention, and do not constitute any form of limitation to the present invention. In the present invention, the power output shaft of the motor can refer to the output shaft of the motor itself, or a reducer can be set behind the motor, and the output shaft of the reducer can be used as the output shaft of the motor power. Any power provided between the motor and the differential The power take-off shaft that the transmission device finally outputs to the differential should be regarded as the power take-off shaft of the motor.
[0009] The rear axle of the adjustable power electric vehicle includes a differential. Two driving motors are arranged on the rear axle, the power of one of the motors is directly or indirectly output to the differ...

The invention discloses a power-adjustable electric vehicle rear axle, and belongs to the technical field of electric vehicle rear axles. The rear axle comprises a differential mechanism, and is provided with two driving motors; the power of one motor is output to the differential mechanism directly or indirectly, and the power of the other motor is connected with a starter drive; the starter drive is connected with a driving wheel of the differential mechanism. According to the power-adjustable electric vehicle rear axle, the two motors can be arranged as required in order to realize different power and torque outputs. The power-adjustable electric vehicle rear axle is simple in structure, and is easy to implement; by adopting the electric vehicle rear axle, the power can be adjusted conveniently.
