Description
Technical field
The utility model is related to the technical field of hybrid vehicle, especially a kind of hybrid electric drive system and has
The motor vehicle driven by mixed power of the drive system.
Background technology
With the development of vehicle technology, people propose increasing requirement, hybrid vehicle to the performance of vehicle
Because it not only has good dynamic property, maneuverability, comfortableness and security, but also oil consumption and discharge can be reduced, it is more next
It is more welcomed by the people.
Hybrid vehicle refer to by it is two or more can while the driver element that operates provides the vehicle of power, it according to
Power independently or is jointly provided according to vehicle actual travel condition selecting different driving unit.In the prior art, most represent
Property hybrid power system have two kinds it is a kind of be the general sharp differential drive pattern applied on this of Toyota, it is a kind of be popular group and
Join drive pattern.
This general sharp differential drive pattern of Toyota includes engine, two motors, preceding planet row and rear planet row, engine
The planet carrier of planet row before direct drive, the sun gear of planet row before the driving of the first motor, planet row after the driving of the second motor
Sun gear, the bull gear that preceding planet row is shared with rear planet row is driven by two couplings between motor and engine, with
The purpose of power mixing is reached, such a scheme can realize hybrid power charged state, hybrid power power-assisted acceleration mode, pure electricity
Dynamic model formula and engine and the multiple-working mode such as motor speed and torque couple dynamic mode, can give full play to engine
Best effort space, and transmission system is simple, without complicated speed changer, accelerator is steady.But this general sharp side of Toyota
The motor of case first can drive engine to rotate in the course of the work, therefore it has following two problems, and first problem is nothing
Method realizes pure engine driving, selects suitable drive pattern effectively to improve power-conversion under the different situations of vehicle
Efficiency, and can be more fuel-efficient, when vehicle high-speed cruise and vehicle use pure engine driving, the transmittance process of power does not have
The conversion back and forth of chemical energy, mechanical energy and electric energy, thus can make vehicle have higher power-conversion efficiency, Toyota it is general it is sharp this
Scheme can not realize pure engine driving, under the situations such as vehicle high-speed cruise power conversion efficiency will be made low, waste energy
Source.Second Problem is under electric-only mode, in order to ensure that engine is static, it is necessary to make the second motor have with the first motor
Opposite rotation direction, this can waste the energy, and due to being shown by two motor speeds, under electric-only mode, highest
Speed about can only achieve 50km/h than relatively low, if desired higher speed, must just make engine participation work.
The parallel drive pattern of popular group is one motor of addition between traditional engine and speed changer, in motor
Both sides respectively arrangement one clutch, or only between engine and motor arrange a clutch, such a structure can be most
Existing part is utilized to limits, the hybrid power of vehicle is realized with minimum change, and a variety of drivings can be realized
Pattern, such as mixed dynamic charge mode, mixed dynamic power-assisted acceleration mode, pure electric Drive Mode, pure engine drive mode and Brake Energy
Measure take-back model etc..But, the motor and clutch added due to this structure is on the power input shaft of engine, therefore
It has following two problems, and first problem is that the arrangement space needed for the program is larger, and horizontal front drive vehicle can not be arranged, passes
Unite front drive vehicle cabin Y direction it is compact, due to the addition of motor and clutch, the crankshaft direction of power assembly need compared with
Big size, thus horizontal platform is difficult to meet the space needed for such a project of network substantially.Second Problem is, it is impossible to realize
The double of rotating speed and torque couple, and engine best effort interval is small, the input of program engine and speed changer be it is coaxial, because
When this engine is coupled with motor progress power, the rotating speed of engine and motor is the same, can only carry out moment of torsion regulation, it is impossible to
Carry out rotating speed as the scheme in this general sharp scheme of Toyota to couple with the double of moment of torsion, so the best effort interval of engine has
Limit, it is impossible to the mixed dynamic effect being optimal.

Between buncher 50 there is normal power to transmit.Motor 20 worked except in some special circumstances, when such as shifting gears with
Outside the rotating speed for adjusting planet row 30, remaining time is in non-working condition, and whole power that engine 10 is exported pass through row
Star row 30 is transferred to buncher 50.The pattern can be transmitted effectively to the power that engine 10 is exported.
Braking mode：In such a mode, first clutch 41 is in releasing orientation, engine 10 and planet row 30
Disconnect, planet row 30 is no longer influenceed with the respective motion of engine 10 by other side.Second clutch 42 is compressed, sun gear
31 are combined with gear ring 33, and planet row 30 is locked, and planet row 30 becomes an entirety, sun gear 31, planetary gear 32 and gear ring 33
Rotate integrally, the speed ratio of the input of the power of planet row 30 and output is 1.Brake 44 is unclamped, and planet carrier 34 can be rotated freely.The
Three clutches 43 are compressed, and between planet row 30 and buncher 50 there is normal power to transmit.Power is passed from planet row 30
Motor 20 is handed to, motor 20 is in charged state.Because now first clutch 41 is in releasing orientation, engine 10 and row
Star row 30 separates, and therefore, this state can eliminate the influence that the tractive torque of engine 10 is caused to planet row 30, more effectively
Ground carries out the energy regeneration based on motor 20.
Neutral mode：In such a mode, first clutch 41 is in releasing orientation, and engine 10 disconnects with planet row 30 to be connected
Connect, planet row 30 is no longer influenceed with the respective motion of engine 10 by other side.Second clutch 42 unclamps, sun gear 31 and tooth
Circle 33 is separated from each other, normal rotation between each part of planet row 30.Brake 44 is unclamped, and planet carrier 34 can be rotated freely.The
Three clutches 43 are unclamped, and the power transmission between planet row 30 and reducing gear 60 is cut off.
Charging/engine start pattern：In such a mode, first clutch 41 is compressed, engine 10 and the phase of planet row 30
Even, the power of engine 10 can be exported to planet row 30.Second clutch 42 is compressed, and sun gear 31 is combined with gear ring 33, OK
Star row 30 is locked, and planet row 30 becomes an entirety, and sun gear 31, planetary gear 32 and gear ring 33 are rotated integrally, planet row 30
Power inputs the speed with output than being 1.Brake 44 is unclamped, and planet carrier 34 can be rotated freely.3rd clutch 43 unclamps, OK
Power transmission between star row 30 and reducing gear 60 is cut off.Under such a state, motor 20 is acted as motor
To start engine 10, or motor 20 is acted as generator 20, the output power of engine 10, is arrived by planet row 30
Motor 20 is charged after up to motor 20.Because now the 3rd clutch 43 is in releasing orientation, the power of planet row 30 is not
Reducing gear 60 can be transferred to, therefore, more effectively motor 20 can be charged under the state.
Three-motor driving mode (retrogressing)：In such a mode, first clutch 41 is in releasing orientation, engine 10
Disconnected with planet row 30, planet row 30 is no longer influenceed with the respective motion of engine 10 by other side.Second clutch 42
