Star wheel frame 404 connects.Second gear ring 503 and the driving coupling of wheel 6.Wherein, " it is enclosed on " and refers to：First power transmission shaft 9 is through the
Two sun gears 501, but the relation of being fixedly connected is had no between the second sun gear 501 and the first power transmission shaft 9, i.e. the second sun gear 501
It will not be rotated with the rotation of the first power transmission shaft 9, the statement that be hereinafter related to a part is enclosed on another part has
Identical implication.
By setting the second sun gear 501, the second planetary gear 502, the second gear ring 503, and it is enclosed on the second sun gear 501
On first power transmission shaft 9, while the second 5 normal work of planetary gear train is ensured, the space in automobile is saved.By by second
Planetary gear 502 is connected by bearing pin with planetary wheel carrier 404, ensure that the second planetary gear 502 is connected fastening with planetary wheel carrier 404,
The coaxially connected of the first planetary gear 402 and the second planetary gear 502 is realized simultaneously.Due to the second sun gear 501 and first sun
The external diameter of wheel 401 is different, and therefore, under identical power, both rotating speeds are different, i.e. the first planetary gear train 4 and the second planet
The gearratio of train 5 is different, and then causes the rotating speed of wheel different, and two gears are added equivalent to for automobile.
In order to realize respectively to the locking of the first sun gear 401 and the second sun gear 501 (i.e. fixed), to ensure that automobile can
With the normally travel under above-mentioned two gear respectively, as shown in accompanying drawing 1- accompanying drawings 5, the hybrid power system also includes：For locking
The only second clutch 10 of the first sun gear 401, the 3rd clutch 11 for the second sun gear of locking 501.
Specifically, it is operated alone in motor 2 during wheel 6 rotates, when second clutch 10 engages, the first sun gear
During 401 locking, the power that motor 2 exports is transferred to the first planetary gear 402 after the first gear ring 403, due to the first planetary gear 402
Coaxially connected with the second planetary gear 502, now, the first planetary gear 402 rotates around the first sun gear 401, drives the second planetary gear
502 rotate, and then make the second planetary gear 502 drive the second gear ring 503 and wheel 6 to rotate.
It is operated alone in motor 2 during wheel 6 rotates, when the 3rd clutch 11 engages, the locking of the second sun gear 501
When, the power that motor 2 exports is transferred to the first planetary gear 402 after the first gear ring 403.Due to the first planetary gear 402 and second
Planetary gear 502 is coaxially connected, and in the case where the second sun gear 501 is locked out, rotation can not occur for the second planetary gear 502.Cause
This, now the first planetary gear 402 can drive the second planetary gear 502 to be rotated around the second sun gear 501, and then make the second planetary gear
502 the second gear rings 503 of drive and wheel 6 rotate.
