In formula: Te is the output torque of engine 54；Tp3It is the output torque of the second motor 102；TinIt is input torque.
This torque is equivalent to twice of 54 output torque of common engine, it is ensured that the good accelerating ability of automobile.
5. shift
When engine 54 drives, first clutch 7 and brake 30 are engaged, the torque of engine 54 is through first clutch
7 pass on the first input shaft 2.First sun gear 25 of first planetary gear mechanism 104 is wheel for inputting, and the first gear ring 16 is output
Wheel, the speed ratio of first planetary gear mechanism 104 are α2。α2It is the gear ratio of the first gear ring 16 and the first sun gear 25.General α2Value
It is located between 2 to 3.
When speed is higher than setting value, release brake 30, in conjunction with second clutch 4, first planetary gear mechanism 104
First sun gear 25 rotates at the same speed with first planet carrier 27, and the speed ratio of first planetary gear mechanism 104 is reduced to 1.If output gear
The product of the speed ratio of wheel 15, driven gear 29 and main ratio wheel, differential mechanism gear ring 37 is id, then the second gear that engine 54 drives is total
Speed ratio is just id, just it is used to drive vehicle high-speed cruise or efficiency power generation.One gear overall ratio is idα2, can be used to assist motor
It starts or accelerates.
Second motor 102 only needs engagement brake 30 to achieve that a gear speed ratio when driving.One gear overall ratio are as follows:
When speed is higher, release brake 30, in conjunction with second clutch 4 (C0), 104 speed ratio of first planetary gear mechanism is
1, second gear overall ratio:
One grade and two grades in the utility model is gear title, is not to refer in particular to be arranged in order in automobile gearbox
Gear.
6. vehicle braking energy recycles
In vehicle deceleration braking, brake 30 is combined, and vehicle inertia is dragged through differential mechanism 35, differential mechanism output axle shaft 34
Differential mechanism gear ring 37, the first sun gear 25, the first input shaft 2, the second planet carrier 53, the second gear ring 21 and the second rotor 19 hair
