Description

A kind of electronic gear shifting actuating mechanism
Technical field
The present invention relates to a kind of automobile mechanism, especially a kind of gear shifting actuating mechanism of automobile.
Background technique
Along with the development of national economy and social demand, increasing automobile has been come into ordinary family.In face of the huge market demand, for the Security of driving, travelling comfort and convenience, have higher requirement.In current automotive control system, automobile electronic control unit has played vital effect, and automobile electronic control unit to be control by signal reach controls travel condition of vehicle and other parameters.With respect to traditional machinery, control, SC sigmal control has long service life, performance safety is reliable, can not only improve the travelling comfort of driving, and does not lose again Driving.Above advantage based on automatically controlled, on automobile, increasing structure and system have been abandoned traditional machinery control, all change electronic unit into, such as E-Gas and electronic throttle etc.This variation is a kind of trend, for this development trend, proposes again the concept of electronic automatic catch gearbox now.The known selector for automatic catch, has P, R, N, tetra-gears of D, is respectively used to parking, reversing, neutral and the object of travelling, and by driver, according to driving intention, selects corresponding gear.Automatic catch gearbox is exactly the gearbox using on traditional automatic catch automobile, although be called automatic catch, but the conversion between gearbox P, R, N, D gear remains by driver's operation selector and carrys out mechanical control with wire drawing, so not only reduce the working life of some mechanism of gearbox, and the part action that is to say gearbox is according to people's intention, to complete completely, so just, cannot evade the damage to gearbox and miscellaneous part that misoperation brings, and likely produce driving danger.
Summary of the invention
The technical problem to be solved in the present invention 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 invention 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 invention 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 invention, 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 invention is direct current generator.Adopt direct current generator to be conveniently applied in existing automobile circuit.
Reducing gear of the present invention 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.
Beneficial effect of the present invention is: 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.

Fig. 1 is the structural drawing of actuator of the present invention;
Fig. 2 is the inner rotating shaft schematic diagram of actuator of the present invention;
Fig. 3 is controller annexation figure of the present invention.
Embodiment
As shown in figs. 1 and 3, a kind of electronic gear shifting actuating mechanism provided by the present invention comprises: angular displacement sensor 1, housing 2, drive motor 3, reducing gear 5, support 6, axle sleeve 7, rotating shaft 8 and for receiving the controller of selector and automobile electronic control unit signal, housing 2 is fixedly mounted on support 6, drive motor 3, reducing gear 5 and rotating shaft 8 are arranged on housing 2 inside, angular displacement sensor (1) is fixedly mounted on housing 2 outsides, one end connecting bushing 7 of rotating shaft 8, axle sleeve 7 is connected for the gearshift crank with gearbox through support 6, the other end of rotating shaft 8 is connected with angular displacement sensor 1 through housing 2, drive motor 3 is by reducing gear 5 drive shafts 8, controller is connected with drive motor 3 with angular displacement sensor 1 respectively, also be connected with automobile electronic control unit with the selector of automobile simultaneously.
When driver shifts gears, first by selector, the electrical signal of driver's gear shift operation is sent to controller, automobile electronic control unit is by automobile speed simultaneously, gear signal and driver-side door switching signal send to controller, each signal that controller comprehensively receives is again controlled drive motor 3, drive motor 3 is by reducing gear 5 drive shafts 8, rotating shaft 8 drives the gearshift crank of gearbox again by axle sleeve 7, thereby carry out electronic gearshift function, angular displacement sensor 1 gathers the angular displacement of rotating shaft 8 simultaneously and feeds back to controller, thereby the carrying out of realizing the rotation angle of countershaft 8 accurately controlled.
