Abstract
The invention relates to the field of electric vehicles, in particular to an electric vehicle with a continuously variable transmission, which can solve the technical obstacle of an automatic transmission of the electric vehicle. The continuously variable transmission is connected between a vehicle driving motor and wheels through a connecting part for transferring power. The vehicle can be only driven by the motor, the output power of the vehicle driving motor is used for driving the vehicle through the continuously variable transmission, and an output shaft of the vehicle driving motor is not linked with the continuously variable transmission through a clutch. The continuously variable transmission with mechanical pressurization and mechanical and electronic control is used, thereby being capable of ensuring that the transmission can work normally from zero rotational speed. The motor is directly connected with a driving shaft of the transmission, so that the starting clutch is unnecessary any longer. As the motor can rotate reversely, the reverse gear is also unnecessary in the transmission. The electric vehicle with the continuously variable transmission can improve the safety of the electric vehicle, improve the endurance mileage and the economy of the electric vehicle and improve the starting acceleration and the power performance of the electric vehicle.
Description
Technical field:
