Summary of the invention
The technical problems to be solved in the utility model is: automatic catch gearbox adopts wire drawing to come mechanical control, the working life of not only having reduced gearbox, and the damage to automobile gearbox that can not avoid misoperation to bring.
In order to address the above problem, the utility model provides a kind of electronic gear shifting actuating mechanism, comprise angular displacement sensor, housing, drive motor, reducing gear, support, axle sleeve, rotating shaft and for receiving the controller of selector and automobile electronic control unit signal, housing is fixedly mounted on support, drive motor, reducing gear and rotating shaft are arranged on enclosure interior, angular displacement sensor is fixedly mounted on outside, one end connecting bushing of rotating shaft, axle sleeve is used for being connected with the gearshift crank of gearbox through support, the other end of rotating shaft is connected with angular displacement sensor through housing, drive motor is by reducing gear drive shaft, controller is connected with drive motor with angular displacement sensor respectively.
Adopt controller to receive the electrical signal of selector and the vehicle signal of automobile electronic control unit, and the signal comprehensively receiving controls drive motor, thereby realize, utilize electrical signal to control the gearshift of gearbox; Adopt angular displacement sensor gather the angular displacement of rotating shaft and feed back to controller, thereby realize the accurate control of countershaft.
Rotating shaft of the present utility model is provided with groove and final-stage gear, is provided with bayonet lock in groove, and final-stage gear is meshed with reducing gear, and housing is provided with bearing, and rotating shaft is connected with angular displacement sensor through bearing, and bearing is stuck between bayonet lock and final-stage gear.Adopt bearing to entangle rotating shaft, can limit the radial displacement of rotating shaft, adopt bayonet lock and final-stage gear to block bearing, can limit the axial displacement of rotating shaft.
In housing of the present utility model, be also provided with motor cover, motor cover is blocked drive motor.Adopt motor cover to block drive motor, drive motor is installed more stable.
Drive motor of the present utility model is direct current generator.Adopt direct current generator to be conveniently applied in existing automobile circuit.
Reducing gear of the present utility model is tertiary gear reducing gear.Employing tertiary gear reducing gear can effectively reduce the driving rotating speed for rotating shaft of drive motor, improves the control accuracy of the rotation angle of countershaft.
The beneficial effects of the utility model are: the conversion between (1) gearbox P, R, N, D gear is by controller, to control drive motor to complete, and has improved the working life of gearbox; (2) action of the part of gearbox is that the relevant information in conjunction with controller completes according to automobile electronic control unit, the damage to gearbox that so just can avoid misoperation to bring.
