The rotating shaft of motor 1 connects the rotating plate of four clutches 27, the driven plate of four clutches 27 connects the input shaft of constant mesh gear group 2, and an input shaft of constant mesh gear group 2 connects the rotating plate of second clutch 3, the rotating plate that another input shaft connects first clutch 25.The driven plate of second clutch 3 connects second input shaft, 7, two fourth gear synchromesh units 5 and is fixed on second input shaft 7; The driven plate of first clutch 25 connects first input shaft, 14, one third gear synchronizers 21 and is fixed on first input shaft 14.Two fourth gear synchromesh units 5 can engage with second gear driving gear 6 or fourth gear driving gear 4, and a third gear synchronizer 21 can engage with one grade of driving gear 22 or third speed drive gear 20.Reverse driving gear 19 is fixed on first input shaft 14, and reverse driving gear 19 with reverse gear driven gear 9 transmission takes place by reverse gear mesomerism gear 12 and cooperates, and reverse gear synchronizer 10 is fixed on the output shaft 11, and reverse gear synchronizer 10 can engage with reverse gear driven gear 9.
Electric machine controller 18 is electrically connected with motor 17, the rotating shaft of motor 17 connects the rotating plate of three-clutch 16, the driven plate of three-clutch 16 connects, motor input driven wheel of differential 13 is fixed on the output shaft 11, angle between the wheel shaft of the wheel shaft of motor input drive bevel gear 15 and motor input driven wheel of differential 13 is 90 °, and motor input driven wheel of differential 13 and motor input drive bevel gear 15 often mesh.Motor 17 can pass through three-clutch 16 like this, drive bevel gear 15 imported by motor and motor input driven wheel of differential 13 is given first input shaft 14 with transmission of power.
The working method of this automatic transmission is as follows:
1. pure electric drive mode
When low vehicle speeds, engine operation efficient is low, therefore adopts pure motor drive mode.At this moment, four clutches 27 separates, first clutch 25 separates, drive connection between motor 1 and the constant mesh gear group 2 is cancelled, three-clutch 16 engages, the power of motor 17 reaches first input shaft 14 through bevel gear pair, by the gear pair on first input shaft 14 power is reached output shaft 11 again, the outputting power driving wheel.The power of motor 17 is not got in touch with second gear and fourth gear are secondary under this pattern, and one grade, third gear and reverse gear are enough to satisfy the running condition of vehicle startup just or low cruise.
When a third gear synchronizer 21 engaged with one grade of driving gear 22, vehicle was with one grade of operation; When speed of a motor vehicle rising needed gear shift, a third gear synchronizer 21 separated, engages with third speed drive gear 20 with one grade of driving gear 22, and power is via third speed drive gear 20 and third gear driven gear 8, by output shaft 14 outputting powers.When a third gear synchronizer 21 mediates, reverse gear synchronizer 10 engages with reverse gear driven gear 9, vehicle moves with reverse gear.
2. pure engine-driving pattern
A period of time of travelling behind vehicle launch enters high speed operation, can adopt pure engine-driving pattern.At this moment, separate three-clutch 16, engage four clutches 27, motor 1 is with normal mode work.First clutch 25 separates, second clutch 3 engages, two fourth gear synchronizers 5 and after second gear driving gear 6 engaged, vehicle moved with second gear.When vehicle quickens, when reaching the third gear shift point, shift control is with a third gear synchronizer 21 and third speed drive gear 20 engagements, gear is changed to third gear in advance, and two fourth gear clutches 3 begin to separate then, and a third gear clutch 25 begins to engage simultaneously, separate fully up to two fourth gear clutches 3, one third gear clutch 25 engages fully, and whole gearshift procedure finishes, and vehicle changes to third gear.In gearshift procedure, the power of motor constantly is passed to wheel all the time, and gearshift procedure is the uninterrupted gear shift of power.
3. combination drive pattern
Can adopt the combination drive pattern to obtain bigger moment of torsion during climbing.This moment is by motor 1 and motor 17 common driving wheel.Four clutches 27 and three-clutch 16 all are in jointing state, both still according to own original power path with transmission of power to output shaft 11.When vehicle during with the operation of a grade or third gear, the power of motor passes on first input shaft 14, and the power of motor 17 also passes on first input shaft 14 via bevel gear pair simultaneously, and both power reaches output shaft 11 jointly by one grade or three-range transmission pair.The power of motor 17 and rotating speed make it coordinate mutually with the power and the rotating speed of motor 1 by electric machine controller 18 controls.When vehicle moves with second gear or fourth gear, the power of motor 1 reaches output shaft 11 via second gear or fourth gear pair, the power of motor 17 reaches on first input shaft 14 via bevel gear pair, reach output shaft 11 by the gear pair on first input shaft 14 again, both power converge on output shaft 11, the torque stack.
4. the transfer process between pure electric drive mode and the pure engine-driving pattern
Under the pure electric drive condition, three-clutch 16 engages, and four clutches 27 separates.When car speed increases, in the time of need transferring engine-driving to by the electricity driving, started under the prerequisite at motor, engaging clutch 27, cut-off clutch 16 promptly transfers the engine-driving pattern to.
