Problems solved by technology

[0003] 1. The existing hand-pull shifting device for electric vehicles has no synchronous action during the shifting process, which will cause problems such as tooth hitting, impact, frustration, noise, etc. during the shifting process, and may easily cause damage to the gear or gearbox
[0004] 2. In the existing hand-pull gearshift device for electric vehicles, the gearshift actuator is composed of pull wires, springs and other mechanisms, and it is impossible to judge whether the gearshift is in place. Over time, it will lead to aging or loosening of purely mechanical mechanisms such as pull wires and springs. Causing disengagement or inabil

Abstract

The invention discloses a gear shifting device of a two-gear transmission of an electric vehicle. The gear shifting mechanism comprises a gear selecting spline (14), a gear shifting shaft (5), a high-gear gear (6) and a low-gear gear (8), wherein a gear shifting shaft output gear (4) is arranged on the gear shifting shaft (5); the gear selecting spline (14) is engaged with the high-gear gear (6) through the pulling of a gear selecting poke (15), or is engaged with the low-gear gear (8); and a gear shifting execution mechanism comprises a gear selecting motor (22), a gearbox (21) and a gear shifting motor output tooth (20) in transmission connection in sequence. The gear shifting mechanism can realize the two-gear shifting, and is convenient for use.

Description

technical field [0001] The utility model relates to a shifting device applicable to a two-speed transmission of an electric vehicle, which belongs to the technical field of variable speed drive and transmission of electric vehicles. Background technique [0002] In order to make the motor work in the high-efficiency zone as much as possible, the application of electric vehicles equipped with transmissions is increasing. But the field of electric vehicles such as existing electric tricycle, electric vehicle, adopts hand-pulled gear shifting device more. This will cause several problems: [0003] 1. The existing hand-pull gear shifting device for electric vehicles has no synchronous action during the shifting process, which will cause problems such as tooth hitting, impact, jerk, noise, etc. during the shifting process, and may easily cause damage to the gear or gearbox. [0004] 2. In the existing hand-pull shifting device for electric vehicles, the shifting actuator is com...
