Summary of the invention
The purpose of this utility model is to provide a kind of dynamic coupling system, it is by the control of a power-transfer clutch, individual drive, electrical generator and main drive motor combine driving separately, the multiple-working modes such as driving combined by three motors to realize electrical generator and main drive motor, under different conditions of demand, adopt different working modes, improve efficiency, save change speed gear box.
The technical solution of the utility model is achieved in that a kind of dynamic coupling system, it is characterized in that: electrical generator and main drive motor integrate, high-speed driving motor and liquid clutch integrate, the main shaft that the rotor of main drive motor connects firmly is connected by the liquid clutch of sun and planet gear with main drive motor front end, sun and planet gear is by sun wheel, satellite gear, pinion carrier forms, the rotor of pinion carrier and electrical generator connects firmly, satellite gear and main shaft connect firmly, the rotor of main shaft and main drive motor connects firmly, sun wheel is connected with high-speed driving motor by liquid clutch, sun wheel, satellite gear, pinion carrier is coordinated by gear.
Good effect of the present utility model is that it not only makes the structure of whole transmission device compacter, and the transmission of epicyclic transmission mechanism is safe and efficient, the rotating speed of three motors and moment of torsion are coupled, while guarantee provides enough large propulsive effort, the wider operation area that have adjusted whole system; By the control of a power-transfer clutch, individual drive, electrical generator and main drive motor combine driving separately, the multiple-working modes such as driving combined by three motors to realize electrical generator and main drive motor, under different conditions of demand, adopt different working modes, improve efficiency, save change speed gear box.
Accompanying drawing explanation
Fig. 1 is dynamic coupling system structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further: as shown in Figure 1, a kind of dynamic coupling system, it is characterized in that: electrical generator 6 and main drive motor 7 integrate, high-speed driving motor 1 and liquid clutch 2 integrate, the main shaft 8 that the rotor of main drive motor 7 connects firmly is connected by the liquid clutch 2 of sun and planet gear 9 with main drive motor 7 front end, sun and planet gear 9 is by sun wheel 3, satellite gear 4, pinion carrier 5 forms, pinion carrier 5 connects firmly with the rotor of electrical generator 6, satellite gear 4 and main shaft 8 connect firmly, the rotor of main shaft 8 and main drive motor 7 connects firmly, sun wheel 3 is connected with high-speed driving motor 1 by liquid clutch 2, sun wheel 3, satellite gear 4, pinion carrier 5 is coordinated by gear.
This dynamic coupling system achieves the object of power dividing, electrical generator 6 and main drive motor 7 are integrated, high-speed driving motor 1 and liquid clutch 2 are integrated, compact conformation, the operation interval of each motor can be optimized by the coupling of many motors, each motor is all run at efficient region, improves the efficiency of automotive power.Power coupling is carried out with sun and planet gear, safe and efficient, retarder function is played to high-speed driving motor, eliminates change speed gear box, by the coupling to rotating speed and moment of torsion, improve the overall operation scope of power system.
Dynamic coupling system of the present utility model comprises following drive pattern:
1, the independent pattern of electrical generator: when vehicle start or low year travel, liquid clutch 2 closes, and electrical generator 6 drives main shaft 8 to drive vehicle by sun and planet gear 9, and main drive motor 7 and high-speed driving motor 1 all do not work;
2, the independent drive pattern of main drive motor: when vehicle needs power is greater than the most service area power of electrical generator, liquid clutch 2 closes, and main drive motor 7 directly drives main shaft 8 to drive vehicle, and electrical generator 6 and high-speed driving motor 1 all do not work;
3, electrical generator and main drive motor associating drive pattern: when vehicle needs power is greater than the most service area power of main drive motor, liquid clutch 2 closes, and electrical generator 6 and main drive motor 7 drive main shaft 8 to drive vehicle, and high-speed driving motor 1 does not work;
4, three motors associating drive patterns: vehicle needs power be greater than electrical generator and main drive motor combine drive most service area power time, liquid clutch 2 disconnects, and high-speed driving motor 1, electrical generator 6 and main drive motor 7 drive vehicle jointly;
5, brake take-back model: when braking or slide, liquid clutch 2 closes, and electrical generator 6 brakes recuperated energy.
