Description
Technical field
The invention belongs to power transmission technical field, specifically, particularly a kind of hybrid power coupling machineStructure.
Background technology
World today's facing mankind energy shortage and ecological deterioration two are challenged greatly, and orthodox car is subject to oil day by dayThe serious puzzlement of crisis, electric automobile has become the main flow of industry development. Wherein, hybrid vehicle existsBalanced economy and the performance of dynamic property aspect are excellent, have become the main development content of electric automobile. And mixPower coupling mechanism has directly determined the method for salary distribution of power, has determined dynamic property and the economy of car load. ExistingSome hybrid power coupling mechanisms generally by one group of planetary gear+two clutch or two groups of planetary gear+two fromClose device and form, there is complex structure, bulky, assembling difficulty, production cost is high, manipulation is inconvenient,The deficiencies such as kinetic equation loss is large, poor reliability.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of simple in structure, compact hybrid power couplingMechanism.
Technical scheme of the present invention is as follows: a kind of hybrid power coupling mechanism, comprises engine (1) and ISGMotor (10) admittedly overlaps the first sun gear (2) on the output shaft of described engine (1), this first sunWheel (2) is positioned at the first outer ring (5), between the first outer ring (5) and the first sun gear (2), is provided withMultiple press even circumferential distribute the first planetary gears (3), each the first planetary gear (3) all with first sunWheel (2) and the first outer ring (5) engagement, and each the first planetary gear (3) is all installed on planet carrier (4)An end face on, on another end face of described planet carrier (4), install multiple by even circumferential distributeThe second planetary gear (7), these second planetary gears (7) are all positioned at the second outer ring (6), and encloseAround the outside of the second sun gear (8), each the second planetary gear (7) all with the second outer ring (6) and secondSun gear (8) is meshed, and described the second outer ring (6) and the first outer ring (5) are all with lockable mechanism, instituteState and on the second sun gear (8), be coaxially fixed with gear wheel (9), this gear wheel (9) and pinion (11)Be meshed, described pinion (11) is sleeved on the main shaft of ISG motor (10).
The present invention has four kinds of mode of operations:
1) engine drives separately: ISG motor is not worked, and first, second outer ring is at lockable mechanism separatelyThe lower locking of effect, engine power is directly inputted to the first sun gear, power by the first planetary gear, OKStar frame, the second planetary gear output to the second sun gear, by the axle of the second sun gear, power are passed to speed changeMechanism. Now, gear wheel drives the idle running of ISG motor by pinion.
2) ISG motor drives separately: ISG motor is drive pattern, and engine is locked, and the first outer ring is decontroled,The second outer ring locking, power directly outputs to the second sun gear by ISG motor by gear wheel.
3) engine and ISG motor drive jointly: ISG motor is electric motor mode, and two with locking machineFirst, second outer ring locking of structure, engine power is directly inputted to the first sun gear, and power is by firstPlanetary gear, planet carrier, the second planetary gear output to the second sun gear; Regulate the rotating speed of ISG motor,Make it and Engine Matching, the power of ISG motor directly outputs to the second sun gear by gear wheel, and realization is turned roundSquare stack.
4) ISG motor charging: ISG motor is generator mode, two with first, the of lockable mechanismTwo outer ring lockings, engine power is directly inputted to the first sun gear, and power is by the first planetary gear, OKStar frame, the second planetary gear output to the second sun gear, and the gear wheel coaxial with the second sun gear passes through little toothWheel drives ISG electric machine rotation to realize generating. Now, the clutch between the second sun wheel shaft and gearSeparate.
The present invention adopts coupled planetary gears, and simple in structure, compact on the one hand, volume is small and exquisite, assemblingEasily, production cost is low; On the other hand, being connected between the present invention and gear only needs a clutchDevice, manipulation is convenient, and kinetic equation loss is little, can guarantee the reliability that power transmits. The present invention is by controlEngine processed, ISG motor and outer ring, realize optimal drive form under different operating modes, met dynamic property requirement,And effectively improve fuel economy.
Arrange for convenient, be conducive to rapid-assembling and dismounting, described the first planetary gear (3) and the second rowStar gear (7) is corresponding one by one, and each the first planetary gear (3) is coaxial with corresponding the second planetary gear (7)Connect.
In order further to strengthen the stationarity that power transmits, as preferably, described the first planetary gear (3) andThe number of the second planetary gear (7) is 3.
The invention has the beneficial effects as follows:
1) can realize the optimal drive form under different operating modes, meet dynamic property requirement, and effectively improve combustionOil economy, simple in structure, compact, volume is small and exquisite, and easily, production cost is low in assembling, and manipulation is convenient,Kinetic equation loss is little, good reliability.
2) only by just reaching that motor and engine singly drive respectively and two to the locking of sun gear with decontrolingThree kinds of operating modes of person's parallel drive, product relatively of the same type can reduce by a clutch.
3) two groups of planetary gears are arranged symmetrically with, and have eliminated the gearratio of planet circular system, make the power can 1:1Output.
4) can directly dock with existing gearbox on market, and it is moving can not affect vehicle because of speed ratio variationPower. Motor is in parallel with engine, can arrange flexibly motor position, effectively utilizes enging cabinFront deck space.
