Embodiment
The embodiment of the present invention is described below in detail, the example of the embodiment is shown in the drawings.Below with reference to The embodiment of attached drawing description is exemplary, it is intended to for explaining the present invention, and is not considered as limiting the invention.
On motor vehicle driven by mixed power, vehicle can arrange multiple drive systems, for example, power drive system 1000, this is dynamic Power transmission system 1000 can be used for the front-wheel or trailing wheel for driving vehicle, drive vehicle below with power drive system 1000 It is described in detail exemplified by front-wheel, certainly, in some optional embodiments, vehicle can be combined with the driving of other drive systems The rear wheel of vehicle, so that vehicle is four-wheel drive cars, for example vehicle can be combined with power drive system driving vehicle Rear wheel.
Below with reference to the accompanying drawings power drive system 1000 according to embodiments of the present invention, power drive system is described in detail 1000 can apply on vehicle, such as hybrid vehicle.
As shown in Fig. 1-Figure 20, power drive system 1000 includes：Power source 100, the first generator unit 300, System dynamic output section 401, first mode conversion equipment 402 and second mode conversion equipment 403.
First generator unit 300 includes the first generator unit coupling part 301 and the first dynamotor 302, the first dynamotor 302 is connected with the alternative power coupling of the first generator unit coupling part 301, and system is moved Power output section 401 is connected with the alternative power coupling of power source 100, the coupling of 100 and first generator unit of power source Portion 301 can be connected or be disconnected by 402 power coupling of first mode conversion equipment, power source 100 and system dynamic output section 401 It can connect or disconnect by 403 power coupling of second mode conversion equipment, power source 100 can lead to system dynamic output section 401 The connection of 403 power coupling of second mode conversion equipment is crossed, so that the power from power source 100 passes through second mode conversion equipment Exported after 403 reductions of speed to system dynamic output section 401.
By the connection state, the power that switch the first dynamotor 302 and the first generator unit coupling part 301 Source 100 and connection state, the 100 and first generator unit coupling part 301 of power source of system dynamic output section 401 pass through The connection state of first mode conversion equipment 402, power source 100 pass through second mode converting means with system dynamic output section 401 403 connection state is put, power drive system 1000 can be made to cut a variety of operating modes.
For example when power source 100 is connected with 401 power coupling of system dynamic output section, power source 100 can be normally defeated Go out power to wheel, connected in power source 100 and system dynamic output section 401 by 403 power coupling of second mode conversion equipment When connecing, second mode conversion equipment 403 will can be exported to system dynamic output section 401 after the power reduction of speed of reception, so that Power drive system 1000 cuts ultralow speed gear (L gears).
