In the specific implementation of following described the embodiment of the present application, one grade to seven grades is drive shift, and automobile
Travel speed grade is gradually accelerated from one grade to seven.
Referring to Fig. 1, the embodiment of the present application provides a kind of hybrid power speed change system, the system include the first output shaft 1,
Second output shaft 2, the first input shaft 3, the second input shaft 4, motor assembly 5 and differential gear 6.
Referring to Fig. 1, the first output shaft 1 include 11, seven grades of first speed driven gear, 12, six grades of driven gear driven gear 14,
Two grades of masters of driven gear 15, first subtract gear 17 and reverse gear duplicate gear 18.
For example, the first output shaft 1 may also include one grade and seven grades of shared synchronizers and two grades and six grades of shared synchronizers.
In a kind of implementation of the embodiment of the present application, a synchronization is used between two different stalls driven gears
Device can save space.For example, a synchronizer is shared between first speed driven gear 11 and seven grades of driven gears 12, at six grades
A synchronizer is shared between driven gear 14 and two grades of driven gears 15, can save the occupied space body of the system in this way
Product.
When automobile with the speed of any gear in one grade, two grades, six grades or seven grades on the first output shaft 1 when driving,
One master, which subtracts gear 17, can reduce the revolving speed of the driven gear of current engaged gear on the first output shaft 1, obtain higher output
Torque, to obtain biggish driving force to drive running car.
Moreover, in a kind of implementation of the embodiment of the present application, reverse gear duplicate gear 18 and two grades of driven gears 15
It can be integrated, so that the rotation direction of the rotation direction of reverse gear driven gear 25 and drive shift driven gear is on the contrary, realize
The function of vehicle, but also the occupied spatial volume of entire speed change system can be reduced.
Certainly, the application is not limited in the position of reverse gear duplicate gear 18 above-mentioned with two grades of driven gears 15
It is fixed as one, it, can also be by reverse gear duplicate gear 18 and other advances in other implementations of the embodiment of the present application
The driven gear of gear is fixedly connected.
Referring to Fig. 1, the second output shaft 2 include 21, five grades of driven gears 22 of third gear driven gear, fourth gear driven gear 24,
Reverse gear driven gear 25 and the second master subtract gear 27.
Second output shaft 2 may also include third gear and five grades of shared synchronizers 23 and fourth gear and reverse gear shares synchronizer
26。
A synchronizer is shared between third gear driven gear 21 and five grades of driven gears 22, in 24 He of fourth gear driven gear
A synchronizer is shared between reverse gear driven gear 25, can also equally save the occupied space of the system.
In a kind of implementation of the embodiment of the present application, when automobile is with the third gear on the second output shaft 2, five grades, fourth gear
Or in reverse gear any gear speed when driving, it is only necessary to corresponding synchronizer is engaged into gear required for present speed
Driven gear.Second master, which subtracts gear 27, can reduce the revolving speed of the driven gear of current engaged gear on the second output shaft 2,
Higher output torque is obtained, to obtain biggish driving force to drive running car.
Referring to Fig. 1, reverse gear driven gear 25 is connect with reverse gear duplicate gear 18.
For example, one grade to seven grades is drive shift, reverse gear driven tooth in a kind of implementation of the embodiment of the present application
The rotation direction of wheel and the rotation direction of drive shift driven gear, can be directly by reverse gear duplicate gear 18 and two on the contrary, therefore
Shelves driven gear 15 is fixed as one, and reverse gear driven gear 25 can be engaged connection with reverse gear duplicate gear 18.
Referring to Fig. 1, the first input shaft 3 is 21, five grades of first speed driven gear 11, third gear driven gear driven gears 22 and seven
Shelves driven gear 12 provides power, and the second input shaft 4 is 24, six grades of two grades of driven gears 15, fourth gear driven gear driven gears
14, reverse gear duplicate gear 18 and reverse gear driven gear 25 provide power.
For example, the first input shaft 3 can be with the portion on the first output shaft 1 in a kind of implementation of the embodiment of the present application
Partial gear driven gear on stepping position driven gear and the second output shaft 2 engages connection, and the second input shaft 4 is the first output
Other gear driven gears on other gear driven gears and the second output shaft 2 on axis 1 engage connection.Namely first is defeated
Enter axis 3 and the second input shaft 4 is that the first output shaft 1 and the second output shaft 2 provide power.
Since reverse dual-linked gear 18 and two grades of driven gears 15 are integrated, the second input shaft 4 can be double for reverse gear
Join gear 18 and power is provided, so that reverse gear duplicate gear 18 transfers power to reverse gear driven gear 25.
Double clutch structures that the system uses are exactly to provide power by the first input shaft 3 for the driven gear of odd gear,
Power is provided by the second input shaft 4 for the driven gear of even gear.Since gear change is usually odd gear and even gear
Position mutually switching, therefore using this kind of double clutch, it can be pre-positioned in advance before gear switch, first make to be switched shelves
The driven gear rotation of position, when disconnecting the driven gear of synchronizer and current gear, i.e., engageable to be switched gear from
Moving gear and corresponding synchronizer, so as to improve the switch speed of gear.In this way in gearshift procedure, torque is eliminated
Interrupt and almost without loss of machine of torque, fuel-efficient effect may further be played.
Referring to Fig. 1, the first master subtracts gear 17 and the second master subtracts gear 27 and connect with differential gear 6.
In a kind of implementation of the embodiment of the present application, since the system uses double-clutch speed changer, automobile is being mixed
Power provides power when driving, and main the second master subtracted on gear 17 and the second output shaft 2 of first on the first output shaft 1 subtracts tooth
Speed and torque difference between wheel 27, therefore the power between two output shafts can be merged by differential gear 6.
First input shaft 3 is connect with internal combustion engine, and the second input shaft 4 is connect with internal combustion engine and motor assembly 5.
For example, motor assembly 5 only can be connected with the second input shaft 4 in a kind of implementation of the embodiment of the present application
It connects, and internal combustion engine can be connect with the first input shaft 3 and the second input shaft 4.
In this kind of implementation, motor assembly 5 be only used as two grades, fourth gear, six grades and reverse gear the second power source mention
For electric power.So while the car is driving, which can optimize internal combustion engine and motor according to the concrete condition of vehicle
Power distribution between assembly 5, can not only reduce oil consumption but also can reduce cost.
Referring to Fig. 1, the first input shaft 3 may include that one grade of driving gear 31, third speed drive gear 32 and five grades and seven grades are total
