Abstract
The invention discloses a parallel type hybrid power system and an operation method thereof. The parallel type hybrid power system comprises an engine, a motor coaxially arranged with the engine and connected with a first clutch, and a speed changing box, wherein the motor is powered by an external power source or a high-voltage battery. The speed changing box is coaxially arranged with the motor and connected with a second clutch. When the parallel type hybrid power system is matched with a manual mechanical speed changing box, a clutch separation mechanism is not refitted, the whole vehicle control is not changed, the gear shifting operation is easy, and the operation is consistent with the operation of a traditional neutral gear vehicle. When the parallel type hybrid power system is matched with an automatic mechanical speed changing box, in the gear shifting process, the rotation inertia of a motor rotor on a shaft of the speed changing box does not have an influence on the speed changing box, and the requirement on the quality of a traditional vehicle AMT speed changing box is met. In addition, when the vehicle is started, the motor and the engine can provide power simultaneously, and the starting power of the vehicle is sufficient.
Description
Technical field
The present invention relates to field of hybrid power, particularly a kind of parallel connection type hybrid power system and method for operation thereof.
Background technology
Hybrid power system on current world market, divides according to energy flow, is mainly divided into three kinds: parallel connection type hybrid power system, series connection type hybrid power system, series-parallel hybrid electric system.Wherein parallel hybrid system is domestic and international mainstream technology route, its technical characterstic is as shown in Figure 1: driving engine 11, motor 12, change speed gear box 13 are coaxially arranged, driving engine 11 is connected with motor 12 by power-transfer clutch 14, motor 12 can drive vehicle operating separately, driving engine 11 can drive vehicle operating separately, and driving engine and motor can run by multi-power driven vehicle simultaneously.Because parallel connection type hybrid power system is all with change speed gear box, the different gear ratios of change speed gear box is inconsistent, and change speed gear box low-grade location has deceleration increasing and turns round function, therefore its applicable surface is very wide, can use any complex environments such as urban traffic situation, mountain area road conditions, outskirts of a town road conditions.
This technical scheme principle of work: during vehicle start, power-transfer clutch is separated completely, rely on power of motor to drive vehicle start completely, when motor speed is consistent with engine speed, power-transfer clutch combines, and driving engine and motor drive simultaneously; During gearshift, disengaging of clutch, change speed gear box takes off neutral gear, electric machine speed regulation, and the gearshift moment reaches, and change speed gear box enters shelves.
This scheme shortcoming:
1, change speed gear box is when change speed gear box is armstrong's patent change speed gear box (MT) (armstrong's patent change speed gear box): due on change speed gear box one axle with the rotor that a rotor inertia is large, need to provide gear shifting signal to entire car controller, full-vehicle control logic is complicated, clutch release mechanism will be reequiped, complex structure, when shifting gears to driver, lithography grasp requires high, and gearshift difficulty is large, and gearshift probability of failure is high.
2, when change speed gear box is automation change speed gear box (AMT) (self acting mechanical gear box): during gearshift, disengaging of clutch, change speed gear box one axle is with rotor together speed governing, because quality of rotor of motor is large, rotor inertia is large, large to the impact of Synchromous device of gearbox, gearbox gear during gearshift, to change speed gear box quality and reliability requirement high.
3, during vehicle start, can only provide power by motor, driving engine can not participate in work, vehicle start under power.
