Problems solved by technology

[0006] 1. The gear selection guide shaft sensor and the gear shift shaft angle sensor are installed on the gear shift motor and the gear selection motor respectively, and the front-end control is adopted, which makes the control accuracy of gear selection and gear shifting poor
[0007] 2. The shift shaft and the shift rocker are integrated, which makes the structure complicated
[0008] 3. The gear shift shaft adopts a straight-toothed rack, which can rotate relative to the gear shift shaft, making the overall structure of the gear shift shaft more complicated and not compact

Abstract

The invention provides a gear choosing-shifting actuator for automatic speed changers, which comprises a gear-choosing actuator and a gear-shifting actuator, wherein the gear-choosing actuator comprises a gear-choosing guide shaft (4), a gear-choosing guide shaft gear (6) and a gear-choosing guide shaft angle sensor (7), and the gear-shifting actuator comprises a gear-shifting shaft (19), a gear-shifting sensor shaft (3), a gear-shifting rocker arm (32), a gear-shifting shaft rack (21) and a gear-shifting sensor shaft angle sensor (18). The gear choosing-shifting actuator is characterized in that the gear-choosing actuator and the gear-shifting actuator mesh with each other through the gear-shifting shaft rack (21) and the gear-choosing guide shaft gear (6). Due to the technical proposal, the gear choosing-shifting actuator has the advantages of compact structure, high transmission efficiency and strong gear choosing-shifting reliability.

Description

Technical field [0001] The invention relates to a gear selection and shift actuator of an automatic transmission. Background technique [0002] Current manual transmissions, especially multi-block manual transmission vehicles, require the driver to frequently shift gears to meet the needs of the engine power during driving, which causes a lot of physical exertion of the driver, and is prone to the situation of shifting wrong gears or failing to shift gears. In order to overcome the above deficiencies, a mechanical automatic transmission is used in the existing vehicles, which adds an automatic variable speed control system on the basis of a stepped mechanical fixed shaft transmission system, and electronically controls the gear selection mechanism to replace manpower. Complete gear selection and shifting. [0003] Mechanical automatic transmissions can be divided into electro-hydraulic, electro-pneumatic and electromechanical according to the source of driving power. Altho...
