The embodiment of the present invention is applicable to electric vehicle, the line shaft of driving motor of electric vehicle is connected to input shaft 300, utilize shift lever 230 and two sliding axle actuators 271,272 to control two synchronizer shifts, can realize third gear speed and export, concrete gear control method is as follows:
Neutral gear: in an initial condition, the driving disc 412 of left synchronizer all departs from two driven discs 411,413 and engages, the driving disc 422 of right synchronizer all departs from two driven discs 421,423 and engages, the now unpowered output of planet carrier 503, and gearbox is in neutral position;
First gear: under neutral state, sliding axle actuator 271 is utilized to drive left sliding axle 211 to slide to the right, left sliding axle 211 promotes right sliding axle 212 immediately and synchronously slides to the right, two reverse shift forks 221, 222 also move right thereupon, thus stir the shift carriage 414 of two synchronizers, 424 move to right, the right driven disc 413 of the driving disc 412 of left synchronizer and its is engaged, and the driving disc 422 of right synchronizer engages with its right driven disc 423, now planetary gear ring 501 is fixed, planetary sun gear 502 and input shaft 300 are connected, now the power of driving motor of electric vehicle is sequentially through input shaft 300, right synchronizer, sun gear 502, planet carrier 503, transmission part 700 is passed to differential mechanism 600, by differential mechanism 600 outwards outputting power, thus realize first grade of speed output, after sliding axle actuator 271 removes driving force, at shifting fork spring 261, under the elastic force effect of 262, two sliding axles 211, 212 drive two reverse shift forks to return back to initial position, thus stir the shift carriage 414 of two synchronizers, 424 reset, the driving disc of two synchronizers is all departed from driven disc engage, thus return back to neutral state,
Second gear: under neutral state, sliding axle actuator 272 is utilized to drive right sliding axle 212 to slide left, right sliding axle 212 promotes left sliding axle 211 immediately and synchronously slides left, two reverse shift forks 221, 222 are also moved to the left thereupon, thus stir the shift carriage 414 of two synchronizers, 424 move to left, the left driven disc 411 of the driving disc 412 of left synchronizer and its is engaged, and the driving disc 422 of right synchronizer engages with its left driven disc 421, now planetary gear ring 501 is connected with input shaft 300, planetary sun gear 502 is fixed, now the power of driving motor of electric vehicle is sequentially through input shaft 300, left synchronizer, gear ring 501, planet carrier 503, transmission part 700 is passed to differential mechanism 600, by differential mechanism 600 outwards outputting power, thus realize the output of second gear speed, after sliding axle actuator 272 removes driving force, at shifting fork spring 261, under the elastic force effect of 262, two sliding axles 211, 212 drive two reverse shift forks to return back to initial position, thus stir the shift carriage 414 of two synchronizers, 424 reset, the driving disc of two synchronizers is all departed from driven disc engage, thus return back to neutral state,
Third gear: when neutral state, the pressure that shift lever 230 is executed on driving lever guide plate 232 by driving lever spring 250 tension force playbacks downwards, now two cantilevers 241, 242 along the pilot hole 2321 of driving lever guide plate 232, 2322 and in the situation of adduction, so two reverse shift forks 221 can not be interfered with when first grade or second gear, the left and right of 222 is to movement, when needing to use third gear, driving lever actuator 231 is utilized to drive shift lever 230 upward sliding, now driving lever guide plate 232 also can move up thereupon, thus promote two cantilevers 241, 242 make it along the pilot hole 2321 of driving lever guide plate 232, 2322 outwards open in splayed shape and distinguish ejection two reverse shift forks 221, 222, now left cantilever 241 promotes left reverse shift fork 221 and is moved to the left, and right cantilever 242 promotes right reverse shift fork 222 moves right, thus the shift carriage 414 stirring left synchronizer moves to left, and the shift carriage 424 stirring right synchronizer moves to right, the left driven disc 411 of the driving disc 412 of left synchronizer and its is engaged, and the driving disc 422 of right synchronizer engages with its right driven disc 423, now planetary gear ring 501, sun gear 502 is all connected with input shaft 300, planet carrier 503 has been coupled simultaneously gear ring 501, the power of sun gear 502, now the power of driving motor of electric vehicle is sequentially through input shaft 300, two synchronizers are passed to gear ring 501, sun gear 502, gear ring 501, after the power of sun gear 502 is coupled by planet carrier 503 again, differential mechanism 600 is passed to by transmission part 700, again by differential mechanism 600 outwards outputting power, thus realize the output of third gear speed, after driving lever actuator 231 removes driving force, under the elastic force effect of driving lever spring 250, driving lever guide plate 232 returns back to initial position, now two cantilevers 241, 242 remove two reverse shift forks 221, the ejection force of 222, two reverse shift forks 221, 222 immediately at shifting fork spring 261, initial position is returned back under the elastic force effect of 262, thus stir the shift carriage 414 of two synchronizers, 424 reset, the driving disc of two synchronizers is all departed from driven disc engage, thus return back to neutral state.
The dynamic curve figure of Fig. 3 is the dynamic curve figure of the electronic third gear speed planetary variable-speed box of the embodiment of the present invention, Fig. 4 to be the dynamic curve figure of conventional electric second gear speed transmission, Fig. 5 be conventional electric single grade of speed transmission;
Axis of abscissas N in Fig. 3, Fig. 4, Fig. 5 represents motor speed, and axis of ordinates T represents motor torque, and the curve R in these 3 figure is identical, and curve R is resistance suffered by vehicle, and the curve D in these 3 figure is identical, and curve D is motor power curve;
Curve X31, X32, X33 in Fig. 3 are the dynamic curve of three shelves speed of electronic third gear speed planetary variable-speed box, curve X21, X22 in Fig. 4 are respectively the dynamic curve of two shelves speed of traditional second gear speed transmission, and the curve X11 in Fig. 5 is single grade of quick-action force curve of tradition single grade of speed transmission;
As can be seen from Fig. 3, Fig. 4, Fig. 5, when adopting same motor, the gear number of gearbox is more, selectable gear ratio is also more, it is available that the such as gearbox of third gear speed has three kinds of gear ratios, and the gearbox of second gear speed to have two kinds of gear ratios available, single grade of fast gearbox only has a kind of gear ratio, therefore the gearbox of third gear speed compares second gear speed transmission, single grade of speed transmission, and output torque or corresponding wheel drive power and the speed of a motor vehicle all have more advantages.
The embodiment of the present invention is also applicable to need to adopt other electric mechanical equipment of gearbox.
In the embodiment of the present invention, the function of described gear-shifting actuating mechanism has three, one is that control two synchronizers shift into driving disc simultaneously and engage with right driven disc, two is that control two synchronizers shift into driving disc simultaneously and engage with left driven disc, three is control left synchronizer shift to engage to driving disc with left driven disc, control right synchronizer shift to engage to driving disc with right driven disc simultaneously, in other embodiment of the present invention, gear-shifting actuating mechanism also can adopt other structural type that can realize these three functions;
Such as, use two sliding axle actuators, one of them sliding axle actuator can drive left sliding axle to move to left, left sliding axle can be driven again to move to right, another sliding axle actuator can drive right sliding axle to move to left, right sliding axle can be driven again to move to right, now can realize third gear without the need to the corresponding part such as shift lever and cantilever and control.
