The present embodiment dynamical system 100 can realize following common functions:
1) starting and charging of engine 1
Because the crankshaft of engine 1 is attached directly to the rotor of first motor 2, the rotation of first motor 2 can start engine 1. Conversely, the operating of engine 1 can drive first motor 2 to charge the battery.Because 1 major function of engine is power generation, and the first electricity The revolving speed of machine 2 is always consistent with engine 1, and engine 1 should be designed as consistent with the efficient revolving speed area of first motor 2.
2) engine 1 is operated alone
All or part of power of engine 1 can be transmitted to input shaft 6 by engagement clutch when engine 1 operates, if In conjunction with brake 8, the first sun gear 41 on input shaft 6 drives the first gear ring 44 through first planetary gear mechanism 4.First planet Gear mechanism 4 is double planetary gear mechanism, uses double planetary gear mechanism to be to guarantee the first sun gear 41 and the first gear ring 44 It turns to consistent.Output gear 14 on first gear ring 44 is engaged with the driven gear 15 on jackshaft 11, by the power of engine 1 Pass to jackshaft 11.Differential mechanism gear ring 17 on jackshaft 11 on driving gear 16 and differential mechanism 12 engages and jack shaft carrys out band Motor car wheel operating.Certain power can be also distributed when engine 1 is operated alone to charge the battery through first motor 2.It is transported according to vehicle The remaining power of engine 1 can be distributed to first motor 2 by market condition, to improve fuel economy.It can be incited somebody to action in full throttle The moment of torsion control of first motor 2 is 0, and all 1 power of engine are distributed to drive shaft, to guarantee that vehicle starts acceleration.
In the present embodiment, when speed is higher, release brake 8, in conjunction with second clutch 9, first planetary gear mechanism 4 Speed ratio 3 or so drop to the 1 of second gear from a gear.If as soon as the overall ratio of gear is 9, then the speed ratio of second gear becomes 3, just For high-performance cruise or efficiency power generation.
3) motor is operated alone
Second clutch 9 is disengaged, the second motor 3 is started.Second gear ring 54 is fixed in the second planetary gear mechanism 5, the The rotor of two motors 3 drives the rotation of the second sun gear 51, at this point, the output speed of the second planet carrier 52 is reduced to:

If it is required that different reduction ratio, different connecting modes are can be used in the second planetary gear mechanism 5.Rotor is such as connected to Two gear rings 54, the second sun gear 51 or the output of the second planet carrier 52.
4) engine 1 and motor drive simultaneously
Start the second motor 3 and engine 1 simultaneously, engage second clutch 9, the torque of engine 1 subtracts dragging first It is passed on input shaft 6 after the torque of motor 2 through second clutch 9.The torque of second motor 3 is after planetary gear mechanism amplifies It is superimposed upon on input shaft 6.If the torque for controlling first motor 2 is 0, maximum input torque (on input shaft 6) are as follows:
Tin=Te1*TP3
In formula: TeIt is the output torque of engine 1;TP3It is the output torque of the second motor 3;TinIt is input torque;This Torque is equivalent to twice of 1 output torque of common engine, it is ensured that the good accelerating ability of automobile.
5) it shifts gears
When engine 1 drives, engages first clutch 7 and brake 8, the torque of engine 1 are passed through first clutch 7 Onto input shaft 6.First sun gear 41 of first planetary gear mechanism 4 is wheel for inputting, and the first gear ring 44 is output wheel, double row The speed ratio of star gear mechanism is α2。α2It is the gear ratio of the first gear ring 44 and the first sun gear 41.General α2Value be located at 2 to 3 it Between.
When speed is higher than setting value, release brake 8, in conjunction with second clutch 9, the of first planetary gear mechanism 4 One sun gear 41 rotates at the same speed with first planet carrier 43, and the speed ratio of planetary gear mechanism is reduced to 1.If gear mesh output gear 14, The product i of the speed ratio of driven gear 15 and driving gear 16, differential mechanism gear ring 17d, it is assumed that: a=Z46/Z45 (driven gear 15 with The gear ratio of output gear 14, Z refer to the number of teeth of meshing gear);B=Z49/Z48;(differential mechanism gear ring 17 and driving gear 16 Gear ratio, Z refer to the number of teeth of meshing gear), then product of the two is id, id=a*b, just be used to drive vehicle high-speed cruise or Efficiency power generation.One gear overall ratio is idα2, can be used to that motor is assisted to start or accelerate.
Second motor 3 only needs engagement brake 8 to achieve that a gear speed ratio when driving.One gear overall ratio are as follows: idα2α1.Vehicle When speed is higher, release brake 8, in conjunction with second clutch 9, the speed ratio of first planetary gear mechanism 4 is 1.Second gear overall ratio are as follows: idα1
The recycling of 3.6 vehicle braking energies
In vehicle deceleration braking, brake 8 is combined, and vehicle inertia drags the first gear ring through differential mechanism 12, jackshaft 11 44, the first sun gear 41, input shaft 6, planet carrier, the second sun gear 51 and rotor power generation, realize Brake Energy recycling.
