Problems solved by technology

[0002] At present, the automatic transmission shifting actuators used in the common technology in the field of automatic transmission of automobiles in China are all hydraulically driven. Although no other additional automatic shifting actuators are required, the structure of the hydraulic shifting mechanism is complicated. The economy of use is significantly lower than that of a manual shift car
However, when hydraulic components are used as automatic shift actuators, the configured oil pump needs to work continuously to maintain the working oil pressure, so reactive energy is consumed, resulting in higher fuel consumption of automatic transmission vehicles than manual transmission vehicles.
Moreover, the maintenance work of the hydraulic system is relatively complicated, which directly affects the economy of the vehicle.
Cars with manual shift transmission have poor driving comfort, high labor intensity and high requirements for drivers

Embodiment 1

[0021] An executive device for an automatic shift mechanism of an automobile, the automatic shift mechanism actuator includes a base plate 1, a power device, a speed reduction device, and a transmission mechanism. Power unit: gear selection motor 2, and shift motor 3; speed reduction device: worm screw 4, turbine shaft 5, motor screw rod 15, threaded slide rod 16. Transmission mechanism: eccentric arm 6, eccentric arm ejector rod 7, multi-rod end ball bearing 8, multi-rod end ball bearing vertical rod sleeve 9, manual shift lever connecting rod 10, connecting rod adjusting sleeve 11, manual shift Joystick connecting piece 13, pin shaft 14. The connection relationship between the components is as follows: the gear selection motor 2, the shift motor 3 and the multi-rod end ball bearing vertical rod sleeve 9 are fixed on the bottom plate 1, and the multi-rod end ball bearing 8 is installed on the multi-rod end ball bearing vertical rod sleeve 9 On; the eccentric arm 6 is install...

Embodiment 2

[0023] The gear selection motor 2 and the gear shifting motor 3 of the power unit of the automatic shifting mechanism executive device are screw drive motors, and the motors are fixed on the base plate 1, and the power is transmitted to the manual shifting joystick through the transmission mechanism. The transmission mechanism is a screw mechanism. Have motor screw rod 15 to be fixedly connected with gear selection motor 2, shift motor 3 rotating shafts respectively. The threaded sliding rod 16 with external threads cooperates with the motor screw rod 15, and the protruding end of the threaded sliding rod 16 is connected with the rod ends of the multi-rod end ball joint bearings 8 respectively.

Embodiment 3

[0025] An executive device of an automatic gearshift mechanism for an automobile, the gear selection motor 2 and the gearshift motor 3 of the power unit of the automatic gearshift mechanism actuator are a worm gear reduction motor, a screw transmission motor and a gear reduction motor, and the transmission mechanism passes through a multi-rod end ball The head bearing transmits power to the manual shift lever 12 . Other structures are the same as in Embodiment 1.
