Embodiment Construction

[0035] The technical solutions in this embodiment will be clearly and completely described below in conjunction with the accompanying drawings in this embodiment. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0036] It should be noted that all directional indications (such as up, down, left, right, front, back...) in this embodiment are only used to explain the relative relationship between the various components in a certain posture (as shown in the figure). When the positional relationship, movement conditions, etc., if the specific posture changes, the directional indication will also change accordingly.

[0037] In addition, in the present invention, descriptions such as "first", "second" and so on are ...

Abstract

The invention discloses a shift actuator and a gearbox. The shift actuator includes a cylinder body, a rear cover, a static iron core, a moving iron core, a push rod and a coil assembly. The rear cover is arranged on the on the cylinder body, and form a storage space with the cylinder body; the static iron core is connected to the cylinder body; the moving iron core is accommodated in the storage space and is arranged on the rear cover and the static iron core between the cores; the push rod passes through the static iron core and is inserted into the accommodation space and is connected with the moving iron core, and the end of the push rod away from the moving iron core is used to push the shift actuator of the vehicle to move ; The coil assembly is accommodated in the accommodation space and arranged around the static iron core and the moving iron core. The circuit design of the shift actuator provided by the invention is simple and the installation efficiency is high.

Description

technical field [0001] The invention relates to the technical field of gearbox manufacturing, in particular to a shift actuator and a gearbox. Background technique [0002] With the increasing demand for vehicle driving comfort and sense of technology, some vehicles have begun to be equipped with automatic transmissions. In the existing mechanical automatic transmission (AMT) on the market, the operating mechanism for realizing gear shifting includes an electric motor, or realizes gear shifting through a pneumatic valve or a hydraulic valve. The use of the above-mentioned type of actuator requires many types and types of electronic control components, and there are many wire harness circuits. The controller control program is relatively complicated, which makes the circuit design complicated and the processing cost high. [0003] Therefore, it is necessary to provide a novel shift actuator to solve the above technical problems. Contents of the invention [0004] The main...
