Abstract

The invention discloses a gear shifting actuator for reciprocating motion of an AMT gearbox. The gear shifting actuator comprises a cylinder body and a rear cover, the cylinder body is of a transversely-placed I-shaped structure, the left end and the right end of the cylinder body are provided with a first cavity and a second cavity respectively, the first cavity communicates with the second cavity, and the rear cover is connected with the first cavity of the cylinder body through bolts. When a first coil or a second coil is powered on, a movable iron core and a push rod move leftwards or rightwards under the electromagnetic effect, so that a gear mechanism matched with the push rod achieves gear engaging or neutral gear returning; and when the first coil and the second coil are powered on, a first sliding block and a second sliding block are located in the middle of the cylinder body. According to the gear shifting actuator for reciprocating motion of the AMT gearbox, electric energy is converted into mechanical energy in a coil electrifying mode, so that the push rod moves left and right in a reciprocating mode, and gear engaging and gear disengaging in the gearbox are achieved.

Description

technical field [0001] The invention relates to the field of automobile transmission equipment, more specifically, to a reciprocating shift actuator for an AMT gearbox. Background technique [0002] With the increasing demand for vehicle driving comfort and sense of technology, higher-end vehicles are beginning to match automatic transmissions. [0003] Existing AMT transmissions on the market realize the operating mechanisms of shifting gears with motors or through pneumatic valves or hydraulic valves to realize shifting and so on. The use of the above-mentioned type of actuator requires many types and types of electronic control components, and there are also many wiring harness circuits, and the control program of the controller is relatively complicated. [0004] Therefore, how to provide a shift actuator with a simple structure, capable of reciprocating movement, and realizing gear-in and gear-out has become a technical problem urgently to be solved in this field.
