Problems solved by technology

[0004] The above-mentioned gear shift actuator is driven by a worm gear structure, so it has the disadvantage of poor hand feeling during the working process, and the internal resistance of the actuator with this worm gear structure is relatively large, which will lead to incomplete gear shifting of the gearbox. So there is room for improvement

Embodiment Construction

[0029] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0030] Such as figure 1 , figure 2 , image 3 As shown, a shift actuator includes: a base 100, an upper cover 200, a transmission unit, a power unit, and a control unit, wherein a non-worm gear structure is adopted between the transmission unit and the power unit, so the internal resistance is small, It will not affect the shifting accuracy of the gearbox, so the hand feeling during operation is very good, and the shifting accuracy can be greatly improved.

[0031] It is worth noting here that in the prior art, the actuator generally adopts a screw structure or a worm gear structure, especially a worm gear structure for transmission, but the worm gear structure has the disadvantage of relatively large internal resistanc...

Abstract

The invention provides a gear shifting actuator, and belongs to the technical field of gear shifting actuators for vehicles. The gear shifting actuator comprises a base, an upper cover, a transmissionunit, a power unit and a control unit, wherein the base is provided with an installation block connected with a gearbox; the upper cover is arranged on the base, and a sealed cavity is formed betweenthe base and the upper cover; the transmission unit is connected with the base and located in the sealed cavity, the transmission unit is provided with an output end, and the output end is used for being connected with the gearbox; the power unit is arranged in the sealed cavity and in linkage connection with the transmission unit; the control unit is electrically connected with the power unit, and the control unit senses the action of the transmission unit and controls the power unit to move. The gear shifting actuator has the benefits that transmission is conducted by using a non-worm-gearstructure, the internal resistance of the actuator is low, and the gear transmission can be more precise and more thorough.

Description

technical field [0001] The invention belongs to the technical field of gear shift actuators for vehicles, and relates to a gear shift actuator. Background technique [0002] The actuator is a component that controls the speed change of the automobile gearbox. It is widely used in automatic transmission vehicles. The front-end electronic shifter of the automatic transmission vehicle sends a shift command, and the electronic shift actuator performs mechanical actions to drive the transmission to change gears and The gear shifting function is realized by feedbacking the position electric signal at that time. [0003] For example, a Chinese patent with application number 201810142069.6 discloses a shift actuator for new energy vehicles, which adopts three-stage gear transmission; among them, the first and second stages use worm gears, and the third stage is spur gear transmission. , the first-stage gear is composed of the first-stage worm and the first-stage worm teeth; the sec...
