When (right side in Fig. 1-Fig. 3) engagement to the right of the clutch collar of double synchronizer S2, four gear driving gear 4a and I power coupling of input shaft connect
Connect, when the clutch collar of the double synchronizer S2 of input shaft is located at middle position, three gear driving gear 3a, four keep off driving gear 4a not with it is defeated
Enter the connection of I power coupling of axis.Double synchronizers, which are arranged, can reduce the number of synchronizer, and the position of double synchronizers can root
According to needing to adjust, for example, the double synchronizer S2 of input shaft can also be arranged in the gear of four gear driving gear 4a and five driving gear 5a it
Between, the structure type of other arrangements is just no longer described in detail herein.
The power transfer path to be formed is meshed, it can be achieved that not by different gear driving gear and gear driven gear
The output of same revolving speed, torque can be engaged, to realize according to specifically operating condition and environment selection power transfer path
The output of different revolving speed, torque, and then adapt to different driving states and meet a variety of power demands, guarantee that vehicle 1000 exists
There is preferable power performance and the economy performance when driving.
For the speed changer of above structure form, the driving force of engine 30 can be passed to by following six kinds of transmission paths
Output shaft II.
When one gear: clutch C engagement, the driving force that engine 30 exports are transmitted to input shaft I by clutch C, export
The clutch collar of the double synchronizer S1 of axis moves to the left (left side in Fig. 1), makes gear driven gear 1b selection and II power coupling of output shaft
Close connection.In this way, the power transfer path of a gear are as follows: engine 30- clutch C- input shaft I-one keeps off driving gear 1a- mono- and keeps off
Driven gear 1b- output shaft II.
The power transfer path of engine 30 when second gear are as follows: engine 30- clutch C- I-two gear driving gear of input shaft
2a- second gear driven gear 2b- output shaft II.

Shift logic, the intervention of motor generator 10 is showed only as being superimposed in the torque of output end, therefore conventional engines 30 and speed change
The control logic of device and the control logic of motor generator 10 be it is independent, be conducive in this way save producer development time and at
This, is avoided the higher failure rate of system, even if engine 30 and transmission system failure will not influence electronic hair when pure electric vehicle
The power output of motor 10.
Motor generator 10 can be used as generator, for example there is power-driven system 100 deceleration/Brake Energy to recycle work
Condition, in deceleration or braking, energy passes to motor generator 10 by gear driven gear from wheel, realizes kinetic energy recycling.
Motor generator 10 is arranged at gear driven gear, the Working mould of power-driven system 100 can also be extended
Formula.When power generation in parking operating condition, engine 30 works, and motor generator 10 is generator, and clutch C is combined, and input shaft is double synchronous
Device S2 clutch collar moves to the left (left side in Fig. 1), connect three gear driving gear 3a with I power coupling of input shaft, output shaft list
Synchronizer S5 is remained stationary, and disconnects three gear driven gear 3b and output shaft II.In this way, the power transfer path of power generation in parking
Are as follows: engine 30- clutch C- input shaft I-three keeps off driven gear 3a- tri- and keeps off driven gear 3b- motor generator 10.
