Description
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 the demand of society, ordinary family come into by increasing automobile.In face of the huge market demand, the Security of driving, travelling comfort and convenience are had higher requirement.In current automotive control system, automobile electronic control unit serves vital effect, and automobile electronic control unit is reached by the control of signal to control travel condition of vehicle and other parameters.Relative to traditional Mechanical course, SC sigmal control has long service life, performance safety is reliable, can not only improve the travelling comfort of driving, not lose Driving again.Based on automatically controlled above advantage, on automobile, increasing structure and system have abandoned traditional Mechanical course, all change electronic unit into, such as E-Gas and electronic throttle etc.This change is a kind of trend, for this development trend, proposes again now the concept of electronic automatic catch gearbox.The known selector for automatic catch, has P, R, N, D tetra-gears, is respectively used to parking, reversing, neutral and traveling object, selects corresponding gear by driver according to driving intention.Automatic catch gearbox is exactly the gearbox that traditional automatic catch automobile uses, although be called automatic catch, but the conversion between gearbox P, R, N, D gear remains and carrys out Mechanical course by driver's operation selector with wire drawing, so not only reduce the working life of some mechanism of gearbox, and that is the partial act of gearbox has come according to the intention of people completely, so just, the damage to gearbox and miscellaneous part cannot evading that misoperation brings, and it is dangerous likely to produce driving.
Summary of the invention
The technical problem to be solved in the present invention is: automatic catch gearbox adopts wire drawing to carry out Mechanical course, not only reduces the working life of gearbox, and the damage to automobile gearbox that misoperation can not be avoided to bring.
In order to solve the 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 the controller for receiving 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 receive the electrical signal of selector and the vehicle signal of automobile electronic control unit, and Integrated Receiver to signal control drive motor, thus realize utilize the gearshift of electrical signal to gearbox to control; Adopt angular displacement sensor gather the angular displacement of rotating shaft and feed back to controller, thus 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, the radial displacement of rotating shaft can be limited, adopt bayonet lock and final-stage gear to block bearing, the axial displacement of rotating shaft can be limited.
Also be provided with motor cover in housing of the present invention, motor cover blocks 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.Direct current generator is adopted can be conveniently applied in existing automobile circuit.
Reducing gear of the present invention is three-stage gear reduction mechanism.Adopt three-stage gear reduction mechanism effectively can reduce the driving rotating speed for rotating shaft of drive motor, improve 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 controls drive motor by controller to have come, and improves the working life of gearbox; (2) partial act of gearbox has come according to the relevant information of automobile electronic control unit in conjunction with controller, so just can avoid the damage to gearbox that misoperation brings.
Accompanying drawing explanation

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, the electronic gear shifting actuating mechanism of one 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 the controller for receiving selector and automobile electronic control unit signal, housing 2 fixedly mounts on the frame 6, drive motor 3, it is inner that reducing gear 5 and rotating shaft 8 are arranged on housing 2, it is outside that angular displacement sensor (1) is fixedly mounted on housing 2, one end connecting bushing 7 of rotating shaft 8, axle sleeve 7 passes support 6 for being connected with the gearshift crank of gearbox, 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 shaft 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 the gear shift operation of driver is sent to controller, automobile electronic control unit is by automobile speed simultaneously, gear signal and driver-side door switching signal send to controller, controller again Integrated Receiver to each signal control drive motor 3, drive motor 3 is by reducing gear 5 drive shaft 8, rotating shaft 8 drives the gearshift crank of gearbox again by axle sleeve 7, thus perform electronic gearshift function, angular displacement sensor 1 gathers the angular displacement of rotating shaft 8 simultaneously and feeds back to controller, thus the carrying out realizing the rotation angle of countershaft 8 accurately controls.
As illustrated in fig. 1 and 2, rotating shaft 8 is provided with groove 11 and final-stage gear 12, and bayonet lock 10 is contained on groove 11, final-stage gear 12 is meshed with reducing gear 5, housing 2 is provided with bearing 9, and rotating shaft 8 is connected with angular displacement sensor 1 through bearing 9, and bearing 9 is between bayonet lock 10 and final-stage gear 12.When rotating shaft 8 is connected with angular displacement sensor 1 through bearing 9, due to the effect of bearing 9, rotating shaft 8 can not be moved radially, again because bearing 9 is stuck between bayonet lock 10 and final-stage gear 12, thus define moving axially of rotating shaft 8.
As shown in Figure 1, be also provided with motor cover 4 in housing 2 of the present invention, motor cover 4 blocks drive motor 3.Adopt motor cover 4 to block drive motor 3, drive motor 3 is installed more stable.
As shown in Figure 1, reducing gear 5 of the present invention is three-stage gear reduction mechanism.Adopt three-stage gear reduction mechanism effectively can reduce the driving rotating speed for rotating shaft 8 of drive motor 3, improve the control accuracy of the rotation angle of countershaft 8.
