[0053] see figure 1 with image 3 A power drive system provided by the first embodiment of the present invention includes an engine 1, a motor 2, a first clutch 3, a second clutch 4, a third clutch 5, a first input shaft 10, a second input shaft 11, a first Three input shafts 12, output shafts 13, first gear set 14, second gear set 15 and third gear set 16;
[0054] The engine 1 is connected to the first input shaft 10, the second input shaft 11 and the third input shaft 12 respectively through the first clutch 3, the second clutch 4 and the third clutch 5;
[0055] The first input shaft 10, the second input shaft 11 and the third input shaft 12 are connected to the output shaft 13 through the first gear set 14, the second gear set 15 and the third gear set 16, respectively;
[0056] The motor 2 is connected to the third input shaft 12 or the output shaft 13;
[0057] The first gear set 14 , the second gear set 15 and the third gear set 16 correspond to three speed ratios. ...

[0118] In this embodiment, a fourth clutch 6 is added on the basis of the first embodiment. in:
[0119] When the motor 2 is connected with the third input shaft 12, the motor 2 is connected with the third input shaft 12 through the fourth clutch 6 (see figure 2 );
[0120] If the fourth clutch 6 is engaged: the power transmission route from the motor 2 to the third input shaft 12 is: motor 2 -> fourth clutch 6 -> third input shaft 12, the power transmission from the third input shaft 12 to the motor 2 The route is: the third input shaft 12->the fourth clutch 6->the motor 2; further, if there is also a speed-up gear set, the route from the motor 2 to the third input shaft 12 is: the motor 2->the first Four clutches 6->speed-up gear set->third input shaft 12, the route from the third input shaft 12 to the motor 2 is: third input shaft 12->speed-up gear set->fourth clutch 6->motor 2;
[0121] When the motor 2 is connected with the output shaft 13, the motor 2 is connected w...

[0132] see Figure 7 In this embodiment, on the basis of the first embodiment, the speed-increasing gear set is set as a planetary gear mechanism 8, the sun gear 801 of the planetary gear mechanism 8 is connected to the motor 2, and the planet carrier 802 of the planetary gear mechanism 8 is connected to the third input The shaft 12 is connected, and the ring gear 803 of the planetary gear mechanism 8 is connected with the brake 7 . Other structures of the third embodiment are the same as those of the first embodiment, and will not be repeated here.
[0133] When the motor 2 is required to generate power or drive, engage the brake 7 to realize the connection of the motor 2 to the drive and power generation circuit; the power transmission route from the motor 2 to the third input shaft 12 is: motor 2 -> sun gear 801 -> planetary gear 804->planet carrier 802->third input shaft 12, the power transmission route from third input shaft 12 to motor 2 is: third input shaft 12->planet...
