Gear-shifting actuator for new energy automobile

Abstract

The invention relates to a gear-shifting actuator for vehicles, in particular to an automatic gear-shifting actuator suitable for a new energy automobile. The gear-shifting actuator for the new energyautomobile is transmitted by three stages of gears, wherein the first stage of gear and the second stage of gear adopt a worm wheel and worm structure, and the third stage of gear is a straight gear,and the first stage of gear is composed of a first stage of worm and a first stage of worm gear; the second stage of gear is composed of a second stage of worm and a second stage of worm gear; a driving motor is linked to the first stage of worm gear through the worm of the first stage of gear, the first stage of worm gear is linked to the second stage of worm gear through the second stage of worm of the second stage of gear so as to be linked to the third stage of gear of the three stages of gears, and an angle sensor is fixed to the end part of an output shaft of a third-stage transmissiongear. The gear-shifting actuator for the automobile provided by the invention is wide in application. As the integral size is relatively small and small in occupied space, the gear-shifting actuator not only can be used in gear-shifting of the new energy automobile and an automatic driving automobile, but also can replace the conventional fuel automobile handle mode for gear-shifting.

Description

technical field [0001] The invention relates to a gear shift actuator for vehicles, in particular to an automatic gear shift actuator suitable for new energy vehicles. Background technique [0002] Existing gearshift actuators for vehicles, such as CN206377256U, the name is a Chinese utility model patent for gearshift actuators for electric vehicles, which discloses that the DC motor is connected through a coupling, and the helical gear is connected with a worm, so that the angular displacement sensor Detect the rotation position of the gear shaft, send the position information of the gear shaft to the vehicle controller, and obtain the corresponding shift displacement and shift speed information through calculation, and control and adjust the DC motor according to the information to realize the control of the shift process . [0003] However, the existing shift actuator needs to be connected to the transmission through a zipper or a connecting rod during use, so it takes u...
