It should be noted that driving engine 31, torsion vibration absorber 32 and electrical generator 33 not necessarily are connected successively by a main shaft, also can be independent rotating shaft and be connected successively, as long as can realize together rotary work of driving engine 31, torsion vibration absorber 32 and electrical generator 33.
During use, when automobile, during in low speed driving, power-transfer clutch 34 disconnects.Closed-center system 39 drives drive motor 35 normal operations, thereby and realizes normally travelling of vehicle by drive axle 36 transmissions.Now, the electric energy in closed-center system 39 meets while travelling needed electric energy, and driving engine 31 does not start; Electric energy in closed-center system 39 can not meet while travelling needed electric energy, and driving engine 31 starts and drives electrical generator 33 and generated electricity, and then closed-center system 39 is charged, thereby guarantees drive motor 35 normal operations.
When automobile starts to run at high speed (speed of a motor vehicle reach certain numerical value after), power-transfer clutch 34 combinations.Driving engine 31 starts and drives successively output adapter shaft 29 normal operations in electrical generator 33 and drive motor 35, thereby output adapter shaft 29 drives drive axle 36 transmissions, realizes normally travelling of vehicle; Now electrical generator 33 is charged by 37 pairs of closed-center systems 39 of the first electric machine controller.
Now the mode of operation of drive motor 35 is divided into three kinds of situations:
1. when the rate of load condensate of driving engine 31 is normal, rotor 23 idle running in drive motor 35, do not carry out any work done.
2. when the rate of load condensate of driving engine 31 is higher, rotor 23 excitations in drive motor 35, drive motor 35 auxiliary engines 31 are driven, thereby reduce the rate of load condensate of driving engine 31.
3. when the rate of load condensate of driving engine 31 is low, rotor 23 excitations in drive motor 35, drive motor 35 is charged by 38 pairs of closed-center systems 39 of the second electric machine controller.
The series-parallel hybrid electric system provided in the present embodiment, it passes through the output shaft of the rotor 23 in drive motor 35 is connected with the sun wheel 24 of planet circular system, and by output adapter shaft 29, is exported under the effect of planet circular system increase moment of torsion.It makes output adapter shaft 29 when meeting larger output torque, reduced the output torque of the output shaft of rotor 23 as far as possible, thereby make the stator 22 of drive motor 35 own and the size of rotor 23 greatly reduce, and then make drive motor 35 size and weight own greatly reduce.Also make drive motor 35 more be convenient to install and use, greatly improved its range of use, and finally made the overall dimensions of series-parallel hybrid electric system and weight greatly reduce, improved its commonality simultaneously.
