Embodiment 1

[0017] Embodiment 1, an electric vehicle drive mechanism, including a drive motor 1, the drive motor is connected to a transmission system with different gears through a clutch, and the transmission system is connected to the rear wheel, thereby driving the electric vehicle to run.

Embodiment 2

[0018] Embodiment 2, an electric vehicle drive mechanism, including a drive motor 1, the drive motor 1 is connected to a transmission system with four gears through an overrunning clutch 4, and the transmission system is connected to the rear wheels to drive the electric vehicle. The transmission system includes the transmission main shaft 2 and the transmission sub-shaft 3 and engages them. The start plate of the overrunning clutch 4 is sleeved on the transmission main shaft 2 and engages with the motor shaft 5 of the drive motor 1 through the driven teeth 19 and the bridge teeth 17. The overrunning clutch , The one-way cover of 4 is set on the transmission main shaft 1 through the rectangular spline.

[0019] The transmission main shaft 2 comprises the main shaft mandrel 6 and the first speed gear 7, the second speed gear 8, the third speed gear 9 and the fourth speed gear 10 which are arranged on the main shaft mandrel 6 and are connected with the countershaft mandrel 11 of ...

Abstract

The invention provides a driving mechanism of an electric vehicle. The driving mechanism comprises a driving motor and is characterized in that through a clutch the driving motor connects a transmission system which is provided with different shifts. According to the invention, a freewheel clutch is arranged between the driving motor and a trailing wheel. Through the transmission system which is provided with different shifts, power is transmitted to the trailing wheel, thus the speed change of the electric vehicle is realized. When riding the electric vehicle, the shift of the electric vehicle can be changed according to road condition to maximize the energy efficiency of the driving mechanism and guarantee the current of the driving motor in a normal scope of application. Thus the service life of the driving motor is prolonged and the mileage of the electric vehicle is increased.

Description

technical field [0001] The invention relates to a driving mechanism, in particular to an electric vehicle driving mechanism. Background technique [0002] At present, electric vehicles usually use hub-type motors, which cannot achieve variable speed, so that electric vehicles use a variable speed ratio when climbing and driving on flat roads. Therefore, the utilization rate of the motor is not high. Contents of the invention [0003] The purpose of the present invention is to provide an electric vehicle driving mechanism capable of realizing multi-gear transmission. [0004] The object of the present invention is achieved in the following way. An electric vehicle drive mechanism includes a drive motor, which is characterized in that the drive motor is connected to a transmission system with different gears through a clutch. [0005] The above-mentioned transmission system includes a transmission main shaft and a transmission sub-shaft and meshes with each other. The a...
