Start the second motor 102 and engine 54 simultaneously, engage first clutch 7, the torque of engine 54 subtracts dragging It is passed on the first input shaft 2 after the torque of first motor 101 through first clutch 7.The torque of second motor 102 is through the second planet Gear mechanism 103 is also superimposed upon on the first input shaft 2 after amplifying.If the torque for controlling the second motor 102 is peak torque, most Big input torque (on the first input shaft 2) is reachable:
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 present invention is gear title, is not the shelves for refering in particular to be arranged in order in automobile gearbox Position.
