Background technique
Motor vehicle driven by mixed power adopts two kinds of different power sources simultaneously, according to the Placement difference of power system, mainly can be divided into three kinds of structural types, i.e. series, parallel and series-parallel connection.
The feature of cascaded structure is to carry out compoundly with form of power, and motor directly drives generator to the power supply of energy storage device and motor, and motor is used for driving wheel.The feature of parallel-connection structure is to carry out compoundly with mechanical type, and motor links to each other with live axle, motor can be simultaneously as motor and generator with the suffered load of balanced engine.The drive pattern of cascaded structure and parallel-connection structure is relative single, can not give full play to the advantage of hybrid electric drive system.
At present, the normally series-parallel connection pattern of often using in the prior art of hybrid electric drive system.
Existing a kind of series-parallel connection pattern is to realize power distribution between each power unit by planetary gears.In this structure, motor links to each other with planet carrier, and a part of mechanical energy of motor is converted into electric energy by first motor and charges to the power supply of second motor or to energy storage device, and another part mechanical energy directly acts on the gear ring.Second motor links to each other with gear ring simultaneously, and part power and torque are provided.
Existing another kind of series-parallel connection pattern is to realize power distribution between each power unit, for example U.S. Patent No. 6209672 B1 by clutch.In this structure, motor links to each other with first motor, links to each other by clutch between first motor and second motor, and car load power is connected to wheel by the output shaft of second motor.By the joint or the separation of solenoidoperated cluthes, can realize multiple driving pattern.
Above-mentioned two kinds of series-parallel connection patterns all have two motors usually, sometimes also need speed changer, also need planetary gears for first kind of pattern, so complex structure, and it is big to take up room, and are unfavorable for the car load layout and alleviate complete vehicle weight.In addition, owing to need accurately control two motors and motor three, just can make their work coordination unanimity, it is complicated that this system that will make becomes, and the control difficulty strengthens, and is also higher to the reliability requirement of component.
Also having a kind of series-parallel connection pattern in the prior art is to utilize clutch and speed changer to realize power distribution between each power unit.
For example, U.S. Patent Application Publication No. 2006/0254837 A1 discloses a kind of hybrid electric drive system, wherein motor is connected to first input shaft of speed changer by clutch, motor is connected to second input shaft of speed changer, and the power of motor and/or motor passes to wheel by the output shaft of speed changer.First input shaft and second input shaft can be two ends passing a shared main shaft of speed changer, or together the two independently axles that are engaged with each other.During clutch, motor can the single driving vehicle driving (can also control motor and generate electricity this moment), and perhaps motor and motor parallel powered vehicle are travelled.When clutch separation, by motor single driving vehicle driving.In this technological scheme, the power distribution between each power unit mainly is to have utilized clutch, and speed changer mainly plays traditional chronotropic action.Therefore, the drive pattern of this drive system is relatively simple.In addition, the speed changer of use is bulky, is unfavorable for alleviating complete vehicle weight.
In addition, U. S. Patent 5,337,848 and 6,019,698 also disclose similar structure, promptly between motor and speed changer clutch are set, the joint by clutch and disconnect the different driving pattern that realizes vehicle.In addition, the power of motor and motor can be by passing to wheel after the speed changer coupling.There are the problems referred to above equally in this structure, and promptly drive pattern is simple relatively, and is unfavorable for alleviating complete vehicle weight owing to speed changer is bulky.
