Problems solved by technology

[0002] At present, most of the transmission shifting actuators in the field of automobile manufacturing are mechanical manual shifting. Its typical structure is to realize the synchronizer shifting through the manual lever to drive the connecting rod and the shift fork. The main disadvantages are frequent manipulation and high labor intensity.
The typical structure of the hydraulic transmission automatic shift transmission (AT) shift actuator used in some high-end passenger cars is to realize the gear shift by controlling the complex hydraulic system and hydraulic friction clutch through the electronic valve. High consumption, poor maintainability and assembly

Embodiment Construction

[0019] Taking the transmission of six gears as an example below, the present invention will be further described. Wherein the intermediate gear shifting block and the intermediate gear connecting rod have only one piece each, which are respectively two / three speed shifting blocks 9 and two / three speed connecting rods 11.

[0020] Such as figure 1 , 2 , 9, the mechanical automatic transmission shift actuator of the present invention includes a casing 15 and a joystick 6 installed in the casing 15, and the joystick 6 is connected with a motor-driven motor that can make the joystick 6 swing. The joystick swing transmission mechanism A1, the joystick movement transmission mechanism A2 driven by the motor that can make the joystick 6 move, the joystick swing position detection mechanism A3, the joystick movement position detection mechanism A4 and the gear interlock mechanism A5, in the operation The driven gear 5 is fixed on the rod 6 by an elastic cylindrical pin, and the joyst...
