It is 4 input.By the inherent characteristic of differential gear train 4 it is found that the differential gear train 4 can when there are two the input of determining revolving speed
A determining revolving speed is exported, first power source 1 exports revolving speed n1, and the output by controlling the speed regulation power source 5 turns
Fast n2 can constantly regulate the output revolving speed n3 of the differential system, until the output revolving speed n3 and second power source 2
When the rotational speed difference n of revolving speed n0 is less than a threshold value, the revolving speed of first power source 1 and the second power source 2 reaches matching condition,
At this moment the clutch 3 between them is combined, power coupling is completed.In this field, it is considered that rotational speed difference n is not more than 50r/min
It is acceptable on subjective feeling, i.e. when rotational speed difference n is not more than 50r/min, first power source 1 and the second power source 2
Revolving speed reach matching condition.The present invention, which will directly adjust 1 output shaft revolving speed of the first power source in the prior art and be transformed into, to be passed through
Differential system adjusts the output revolving speed of the first power source 1 indirectly, and usual first power source 1 is motor or engine, is used to
Measure larger, and the inertia of the differential gear train 4 itself is much smaller than the inertia of first power source 1, therefore using described differential
Train 4 adjust power source export revolving speed high sensitivity, can quickly reduce the rotational speed difference between power source output shaft, thus reduce from
The impact and abrasion that clutch 3 is subject to extend 3 service life of clutch and improve the reliability and NVH characteristic of package unit.
In another embodiment of the present invention, as shown in Fig. 2, referring also to Fig. 3, the differential gear train 4 includes the
One driving link, the second driving link and executive item, first driving link are planetary gear 401, the planetary gear 401 and described first
Planet carrier 402 is provided between power source 1, one end of the planet carrier 402 is 401 central axis of planetary gear, the other end
It can be connected by first flange 101 with the output shaft 10 of first power source 1, for inputting the first revolving speed n1；Described
Two driving links are outer ring 403, and the outer ring 403 is connected with the output shaft 50 of the speed regulation power source 5, for inputting second turn
Fast n2；The executive item is sun gear 404, the central axis 40 of the sun gear 404 by second flange 102 and close on it is described from
The power source of the clutch 3 i.e. main shaft 6 of the second power source 2 is connected, for exporting third revolving speed n3.The speed regulation power source 5
For stepper motor, it is preferable that the speed regulation power source 5 is that servo motor can be more preferable due to servo motor revolving speed controllable precise
Control its export revolving speed so that the speed regulation of differential gear train 4 is more accurate.
In another embodiment of the present invention, as shown in Fig. 2, referring also to Fig. 3, the multi power source, which couples, to be passed
Dynamic system further includes self-locking mechanism, and the self-locking mechanism is worm gear mechanism, and the outer surface of the outer ring 403 is processed as worm gear
The output shaft of the flank of tooth, the speed regulation power source 5 is processed as worm screw, and the worm gear surface is matched with the worm screw, described in formation
Worm gear mechanism, for keeping the one-directional rotation of the outer ring 403.
Reach matching condition in the 6 revolving speed n3 of main shaft, clutch 3 is by 2 phase of the first power source 1 and the second power source
It is described since the transmission of worm gear mechanism has one-way in conjunction with rear, stepper motor or the extremely stalling of servo motor reduction revolving speed
After stepper motor or servo motor stalling, due to worm gear mechanism reverse self-locking, so that the outer ring 403 of the differential gear train 4
It stops operating, it is fixed than rigid connection that the differential gear train 4 is formed, and steadily exports rotating speed of target, further dissolves to clutch
The impact of device 3.Wherein, servo motor can reduce revolving speed to stalling, so that the deceleration of the outer ring 403 is more flat according to certain ratio
Surely.
Control method one embodiment of multi power source coupled drive of the invention is as shown in Figure 4, comprising the following steps:
Monitoring step S100: the output revolving speed for two power sources that monitoring need to couple and the output for adjusting the speed power source 5 turn
Speed；
