Abstract

The invention relates to a continuously variable transmission for an electric vehicle. The continuously variable transmission comprises a driving wheel, a driven wheel, a track for connecting the driving and the driven wheel, a power input shaft, a power output shaft, and a driving motor for driving the power input shaft to rotate. The driving comprises a first motor, a first supporting stand, a first rotating frame and first supporting frames. The first rotating frame comprises a first upper cylindrical top cover, a first lower cylindrical top cover and a plurality of first installation rods, and the supporting stand is connected with the power input shaft. The driven wheel comprises a second motor, a second supporting stand, a second rotating frame and second supporting frames. The second rotating frame comprises a second upper cylindrical top cover, a second lower cylindrical top cover and a plurality of second installation rods, and the supporting stand is connected with the power output shaft. The continuously variable transmission is applied to the electric vehicle, and the transmission ratio of the continuously variable transmission for the electric vehicle can be changed continuously in a certain range so that flexibility of output power of the electric vehicle can be greatly improved.

Description

technical field [0001] The invention relates to a transmission, in particular to a continuously variable transmission of an electric vehicle. Background technique [0002] CVTs have not been used in electric vehicles. At present, for low-speed pure electric vehicles, the speed ratio of the gearbox is fixed or only a few gears. The range of this speed ratio is very small, which cannot meet the complex road conditions faced by electric vehicles during driving, and the power flexibility of electric vehicles is poor; and electric vehicles cannot make the motor work on its economic power as much as possible, and the economy is also poor. poor. [0003] At present, the belt drive continuously variable transmission has been commercially applied in the traditional fuel vehicle industry. The disclosed commercial V-shaped steel belt continuously variable transmission mechanism is composed of a steel belt pulley, a driven steel belt pulley and a V-shaped steel belt. Partially compos...
