Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, described hybrid vehicle single planetary bevel gear system dynamic coupling device, it comprises driving engine 1, motor 8, and the planet circular system be made up of sun wheel 7, pinion carrier 6, gear ring 5 and satellite gear; It is characterized in that: be connected by first clutch 2 between described driving engine with described pinion carrier, be connected by second clutch 3 between described driving engine with described sun wheel; Described motor 8 is connected with described sun wheel; Described pinion carrier is provided with the first drg 4, described gear ring is provided with second brake 10; Described gear ring 5 is connected with ex-ternal transmission mechanism by power output gear 9, with by transmission of power to automobile driving wheel.
By controlling the engaged/disengaged state of power element and the mode of operations of motor 8 such as first clutch 2, second clutch 3, second brake 4, second brake 10, the multiple typical mode of operation such as the pure motorized motions of hybrid vehicle, generator drive, driving charging, combination drive, regenerative brake, power generation in parking can be realized, under various pattern, the engagement state of power element sees table, wherein "●" represents that power element engages, and "○" represents that power element is separated.
The engagement state of power element under various pattern
Concrete coupling method under each typical mode of operation is as follows:
1) pure motorized motions pattern: under electric-only mode, first clutch 2 is separated, second clutch 3 is separated, and the first drg 4 engages, and pinion carrier 6 maintains static, and described motor 8 is according to load output power.Now, motor 8 reverse drive sun wheel 7 rotate, by sun and planet gear, power is reached gear ring 5, then by power output gear 9 by power stage.Power transimission route under this pattern is: motor 8 → sun wheel 7 → gear ring 5 → power output gear 9.
2) engine drive mode: when vehicle travels with the higher speed of a motor vehicle, required driving power is in the efficacious workaround of driving engine, and now automobile is operated in the independent drive pattern of driving engine.Under this pattern, first clutch 2 engages, second clutch 3 engages, and the first drg 4 is separated, second brake 10 is separated, and sun and planet gear self-locking, integrally operate, and described motor 8 will dally with sun wheel 7 under the drive of driving engine 1.Power transimission route under this pattern is: driving engine 1 → first clutch 2, second clutch 3 → sun and planet gear → power output gear 9.
3) to drive a vehicle charge mode: when driving load is less, during the best effort load of out of reach driving engine 1, described motor 8 runs in either a generation, and the load increasing driving engine 1, to improve its efficiency, improves oil consumption characteristic, maintains cell equalization simultaneously.Under this pattern, first clutch 2 engages, second clutch 3 engages, and the first drg 4 is separated, second brake 10 is separated, and sun and planet gear self-locking, integrally operates under the drive of driving engine 1, and described motor 8 rotates forward generating.Now a horsepower output part for driving engine 1 is passed to motor 8 by sun wheel 7, for generating; Another part is passed to power output gear 9 by gear ring 5, for driving automobile.
4) combination drive pattern is divided into two subpatterns, as follows:
Combination drive modes I: when automobile in climbing, overtake other vehicles or travel under the high load working condition such as acceleration, when required driving power is much larger than the optimal power of driving engine, motor supplements power, and driving engine is still operated on " optimal curve ".Under this pattern, first clutch 2 engages, second clutch 3 engages, and the first drg 4 is separated, second brake 10 is separated, and sun and planet gear self-locking, integrally operate, and described motor 8 rotates forward horsepower output under the drive of driving engine 1.Now, the horsepower output of driving engine 1 and the horsepower output of motor 8 realize being coupled on sun and planet gear, are passed to power output gear 9, jointly drive automobile.
Combination drive mode II: when automobile high-speed cruises, for keeping the speed of a motor vehicle, and making driving engine be in steady-working state, can utilize electric machine speed regulation.Under this pattern, first clutch 2 engages, and second clutch 3 is separated, and the first drg 4 is separated, second brake 10 is separated, and described motor 8 rotates forward and exports smaller power, for speed governing.Now, power transimission route has two: driving engine 1 → first clutch 2 → pinion carrier 6 → gear ring 5 → power output gear 9; Motor 8 → sun wheel 7 → planetary wheel → gear ring 5 → power output gear 9.
5) braking mode: in moderating process, motor can carry out power recovery, vehicle energy is converted into power storage to battery.According to the driving conditions before deceleration, regenerative brake is divided into be had driving engine to drag regenerative brake (B shelves) and drags regenerative brake (D shelves) two kinds of forms without driving engine, as follows:
Driving engine drags braking mode (B shelves): when under automobile during abrupt slope, adopts electrical motor engine combined brake.Under this pattern, first clutch 2 engages, second clutch 3 engages, and the first drg 4 is separated, and second brake 10 is separated, and sun and planet gear self-locking, integrally operates.Now, due to running car inertia, drive sun and planet gear running, a part of power is for overcoming anti-running resistance of dragging driving engine 1; Another part power is used for motor 8 and generates electricity.
Braking mode (D shelves) is dragged: under this pattern, first clutch 2 is separated, and second clutch 3 is separated, and the first drg 4 engages, and pinion carrier 6 is connected with frame, maintains static, and described second brake 10 is separated without driving engine.Due to running car inertia, drive sun wheel 7 to rotate, thus drive motor 8 generate electricity.Now, power transimission route is: power output gear 9 → gear ring 5 → planetary wheel → sun wheel 7 → motor 8.
6) power generation in parking pattern: when the of short duration parking of automobile, in order to avoid the frequent start-stop of driving engine, thus improve car load fuel economy, maintain charge level, power generation in parking pattern is divided into two subpatterns, as follows simultaneously:
Power generation in parking modes I: under this pattern, first clutch 2 is separated, and second clutch 3 engages, first drg 4 is separated, and second brake 10 engages, and gear ring 5 maintains static, driving engine 1 drives sun wheel 7 to rotate by second clutch 3, thus drive motor 8 generates electricity, and pinion carrier 6 dallies.Power transimission route is: driving engine 1 → second clutch 3 → sun wheel 7 → motor 8.
Power generation in parking mode II: under this pattern, first clutch 2 engages, and second clutch 3 is separated, first drg 4 is separated, and second brake 10 engages, and gear ring 5 maintains static, driving engine 1 drives pinion carrier 6 to rotate by first clutch 2, and sun wheel 7 is rotated thereupon, thus drive motor 8 generates electricity.Power transimission route is: driving engine 1 → first clutch 2 → pinion carrier 6 → sun wheel 7 → motor 8.
7) pure electronic reversing mode: when battery allowance is enough, adopt pure electronic reversing mode as far as possible, the characteristic of motor low speed high torque can be given full play to, not only increase the dynamic property of automobile, avoid low engine speed operating condition simultaneously, improve Integral automobile fuel economy.Under this pattern, first clutch 2 is separated, and second clutch 3 is separated, and the first drg 4 engages, and pinion carrier 6 is fixed, and described second brake 10 is separated, and described motor 8 rotates forward and drives, thus drives gear ring 5 to rotate backward, by power output gear 9 by power stage.
