Certainly, the first generator unit 300 can not also arrange rough lock 303, as shown in figure 13, the first electronic hair Motor 302 is optionally connected with 402 power coupling of mode conversion device.
Mode conversion device 402 is used for optionally power coupling connection 200 and first dynamotor list of variable-speed unit First coupling part 301, so that the power in mode conversion device ultromotivity in 402 future source 100 is successively by variable-speed unit 200, pattern Exported after 402 2 reductions of speed of conversion equipment to the first generator unit coupling part 301.
Therefrom, it may be appreciated that power source 100 can be directly passed to system dynamic output by variable-speed unit 200 For the input terminal in portion 401 to export power, i.e., the power that power source 1000 exports is defeated by an output gear of variable-speed unit 200 Go out；Power source 100 can also be exported to the first generator unit coupling by variable-speed unit 200 and mode conversion device 402 Conjunction portion 301, the input terminal that the first generator unit coupling part 301 passes to system dynamic output section 401 again are dynamic to export The power of power, i.e. power source 100 output is exported to mode conversion device 402, pattern after a reduction of speed of variable-speed unit 200 Conversion equipment 402 is exported to the first generator unit coupling part 301 after reduction of speed again, realizes secondary reduction of speed, at this time power Transmission system 1000 enters Ultra-Low Speed gear pattern, and mode conversion device 402 enters L gear patterns.
The drive pattern of power drive system 1000 can be so enriched, and power source 100 can be caused to export to being The power in power output of uniting portion 401 is suitable, in other words, can make it that the rotating speed of wheel is suitable, so as to improve the row of vehicle Sail stability, and driver can be enriched and drive to experience.
Mode conversion device 402 can be also used for optionally power coupling connection 200 and first electronic hair of variable-speed unit Motor 302, so that the power from power source 100 is electronic by variable-speed unit 200, the driving first of mode conversion device 402 Generator 302 generates electricity.
Moreover, mode conversion device 402 can be also used for selective power coupling and connect the first dynamotor list First 301 and first dynamotor 302 of coupling part, so that the power of the first dynamotor 302 output passes sequentially through pattern Conversion equipment 402, the first generator unit coupling part 301 export.
Thus, mode conversion device 402 can have at least three effects, and an effect is by the power of power source 100 The input terminal to system dynamic output section 401 is exported by the first generator unit coupling part 301；Another effect be by The power output of power source 100 is generated electricity to the first dynamotor 302 with the first dynamotor 302 of driving, especially in car When being in parking operating mode, the power output of power source 100 is to the first dynamotor 302 to drive the first dynamotor 302 power generations, generating efficiency is high, and power transfer path is short；Another effect is by the by the power of the first dynamotor 302 One generator unit coupling part 301 exports the input terminal to system dynamic output section 401, so as to realize the electricity of vehicle Drive.
So mode conversion device 402 adds the gear of vehicle, and vehicle max. output torque can be made to amplify N times, and (N is equal to L gears relative to one of variable-speed unit 200 output gear fast ratio), improve dynamic property, handling capacity (such as climb by maximum The gradient, ability of getting rid of poverty).Especially for conventional hybrid vehicle, due to adding battery pack, motor, electric-control system, cause Kerb weight is big, is only capable of relying on the power output of engine after feed, at this moment handling capacity and dynamic property can big heavy discount, and Using the hybrid electric vehicle of the mode conversion device 402 in the present invention, dynamic property and handling capacity can be effectively lifted, is had The drive pattern of abundant vehicle, so that vehicle adapts to more different operating modes.
