Problems solved by technology

However, when the motor is adjusted to run at a low speed, its output power and torque are correspondingly reduced, making the electric vehicle weak during the uphill process. Chinese Patent Publication No. CN201050582Y discloses an electric transmission, and its electric transmission is manually adjusted for shifting operation. Inconvenient, in addition, because the gears of the electric transmission are rigidly combined when shifting, there is an impact feeling when shifting, which will easily damage the machine and make the driver feel uncomfortable

Abstract

The invention belongs to the technical field of the power transmission of an electric motor car, in particular to an automatic variable power transmission mechanism of an electric motor car, comprising a box body, and a motor is arranged on the side wall of the box body and is provided with a motor shaft. The box body is internally provided with an input shaft, an output keyway shaft and an axle, wherein the motor shaft is in transmission connection with the input shaft; the output keyway shaft is in transmission connection with the axle; the input shaft is provided with a high-speed driving gear and a low-speed driving gear; the output keyway shaft is provided with a clutch on which a high-speed driven gear is fixed, a one-way driver is arranged between the output keyway shaft and the low-speed driven gear, the output keyway shaft is provided with a driven keyway sleeve, a driven friction sheet and a driving friction sheet are arranged between the driven keyway sleeve and the clutch, a driving-driven keyway sleeve separating spring is arranged on the end surfaces of the friction sheets, a slope groove is arranged between either friction sheet and the bottom end of the clutch, an eccentric bead is arranged in the slope groove, and an eccentric axial repulsion mechanism is formed by the slope groove and the eccentric bead.

Description

technical field [0001] The invention belongs to the technical field of electric vehicle power transmission Background technique [0002] The driving power of the existing electric vehicle is mainly changed by adjusting the voltage and current input to the motor and changing the speed of the motor. However, when the motor is adjusted to run at a low speed, its output power and torque are correspondingly reduced, making the electric vehicle weak during the uphill process. Chinese Patent Publication No. CN201050582Y discloses an electric transmission, and its electric transmission is manually adjusted for shifting operation. Inconvenient, in addition, because the gear is rigidly combined when the electric transmission shifts gears, there is a sense of impact when shifting gears, which can easily damage the machinery and make the driver feel uncomfortable. Contents of the invention [0003] The purpose of the present invention is to provide a simple structure, small size, fle...
