Then, introduce two retaining forward gears of the driver for vehicle of present embodiment with reference to Fig. 1.When vehicle drove at moderate speed, shifting control system separated with secondary part with the A end of secondary part, three-clutch 10 by the A end of gearshift with first clutch 15, and the A end of second clutch 11 engages with secondary part.For example, when a retaining forward gear is switched to two retaining forward gears, shifting control system passes through relevant sensor sensing to the current running state of vehicle, and then judge that vehicle enters the gear of operation, at the A end of first clutch 15 with when secondary part separates, the A end of second clutch 11 engages with secondary part, thereby reaches the purpose of gearshift.Wherein, the power transmission line of two retaining forward gears is: drive motor 1 → input shaft 2 → the first gears 3 → the second gears 8 → tween drive shaft 13 → second clutch 11 → the 5th gears 12 → the 6th gear 6 → output shaft 5.Those of ordinary skills for example should be known in, can utilize existing shifting control system and gearshift, make the gearshift time can be very short.At this moment, because transmitting ratio is big more, drive motor efficient is low more, so compare with a retaining forward gear, the transmitting ratio of two retaining forward gears is less, and the efficient of drive motor is also higher, and capacity usage ratio is higher.
Then, introduce three retaining forward gears of the driver for vehicle of present embodiment with reference to Fig. 1.When high vehicle speeds, shifting control system separates with secondary part with the A end of secondary part, second clutch 11 by the A end of gearshift with first clutch 15, and the A end of three-clutch 10 engages with secondary part.For example, when two retaining forward gears are switched to three retaining forward gears, with in that a retaining forward gear is switched to two retainings is similar during forward gears, with when secondary part separates, the A end of three-clutch 10 engages with secondary part at the A end of second clutch 11.The transfer route of three retaining forward gears is: motor 1 → input shaft 2 → the first gears 3 → the second gears 8 → tween drive shaft 13 → the three-clutch 10 → the 7th gear 9 → the octadentates wheel 4 → output shaft 5.At this moment, because transmitting ratio is big more, drive motor efficient is low more, thus compare with two retaining forward gears with a retaining forward gear, the transmitting ratio minimum of three retaining forward gears, the efficient of drive motor is also the highest, and capacity usage ratio is the highest.
At last, introduce the reversing gear of driver for vehicle of present embodiment with reference to Fig. 1.When vehicle reverses gear when travelling, shifting control system separates with secondary part by the A end of gearshift with second clutch 11, three-clutch 10, and the A end of first clutch 15 engages with secondary part.It should be noted that drive motor 1 counter-rotating when reversing gear.The power transmission line that reverses gear is: drive motor 1 → input shaft 2 → the first gears 3 → the second gears 8 → tween drive shaft 13 → first clutch 15 → the 3rd gears 14 → the 4th gear 7 → output shaft 5.
