Problems solved by technology

[0002] Existing variable-speed electric tricycles or four-wheeled vehicles mainly change the speed of the motor by adjusting the voltage and current input to the motor, but when the motor is adjusted to run at a low speed, the output power is correspondingly reduced, so that the electric vehicle can move uphill when going uphill. or adjust the gear shift manually, and the driver has to analyze the road conditions to see if he needs to shift gears, which brings inconvenience to the driver of the electric vehicle to control the speed of the electric vehicle according to different road conditions. Inconvenient, directly affects the performance of the best power performance of the electric vehicle motor
There is a problem of flexible and smooth shifting in the manual mechanical shifting motor technology, but there is no fundamental solution to the automatic shifting of electric vehicles according to different road conditions and different speeds of the motor to achieve different power outputs

Abstract

The invention belongs to the technical field of electric vehicle power transmission and solves the problem that the existing electric vehicle motors cannot automatically shift gears. It is an automatic variable speed motor for electric vehicles. The side wall of the box body is provided with an input shaft, an output shaft and a half shaft; the motor shaft is connected to the input shaft for rotation; the output shaft is connected to the differential transmission, and the input shaft is There are high and low-speed driving gears; the output shaft is provided with a clutch to fix the high-speed driven gear, and a one-way transmission is provided between the output shaft and the low-speed driven gear, and the output shaft is provided with a driven gear. The keyway sleeve, the driven friction plate and the active friction plate are arranged between the driven keyway cover and the clutch housing, the friction plate is provided with a friction plate separation spring on the end face, a slope groove is provided between the friction plate and the bottom end of the clutch, and the centrifugal ball is set on In the ramp groove, the ramp groove and the centrifugal ball form a centrifugal axial thrust mechanism.
