Second clutch C2 engages the second planet carrier G4 and input shaft Z1.At this point, the P3 rotations of the first gear ring of driven by engine, driving electricity
Machine M control the first sun gear P1 rotations；The rotating speed of driving motor M is controlled by control unit, changes the rotation of the first sun gear P1
Rotary speed, it will be able to realize the variable speed of engine power.
Therefore, the Simpson hybrid power gearbox of the present embodiment can be operated by engine driving, or can be by driving
Dynamic motor driving operating, additionally it is possible to be operated by engine, driving motor combination drive.It can be applied to hybrid power vapour
Vehicle.
In addition, the hybrid power gearbox structure is relatively easy, by the way that driving motor M is arranged, make the output of driving motor M
End is fixedly connected with the first sun gear P1.And planetary gear speed-changing system can refer to the four gear fluid drive of existing Simpson
Therefore case is easy to manufacture；On the basis of four gear automatic gear-box of Simpson, also it is easy its improvement cost reality
Apply the hybrid power gearbox of example.
Further, this hybrid power gearbox is without fluid torque-converter.In the prior art, four gear of Simpson
Automatic gear-box is arranged fluid torque-converter usually between transmission input and engine output end, and fluid torque-converter can be
When brake pedal, prevents the drawing force from wheel to be directly back to engine, avoid engine misses.
In the present embodiment, in brake pedal, first clutch C1 or first clutch C2 can be detached, and pass through drive
Dynamic motor M driving operatings, to realize running car.Therefore, the drawing force from wheel will not directly be back to engine, can
Avoid engine misses.
Due to being not necessarily to that fluid torque-converter is arranged, then, this in four gear automatic gear-box of prior art Simpson is for setting
The space for setting fluid torque-converter can be used for that driving motor M is arranged, it is not necessary that other accommodation spaces are being arranged to be used for accommodating drive
Dynamic motor M, can further facilitate the processing and manufacturing or transformation of the hybrid power gearbox.
Referring in particular to Fig. 1, gear box casing K includes the first shell K1 set gradually in an axial direction and second shell K2.Its
In, planetary gear speed-changing system is arranged in first shell K1；This is used to be arranged the second shell K2 of fluid torque-converter, in this reality
It applies in example, can be used for that driving motor M is arranged.
It should be noted that in other variations, fluid torque-converter can also be retained, driving motor M can be with fluid power
Torque-converters is co-located in second shell K2；Alternatively, being arranged driving motor M outside gear box casing K.
Further, this hybrid power gearbox is without reverse clutch (REV).It can be controlled by control unit
Driving motor M processed is rotated forward or reversion, realizes that first planet carrier P4 is reversely rotated, to realize reversing.Become therefore, it is possible to simplify
Fast box structure reduces manufacturing cost.
In addition, as described above, by control driving motor M rotating speed, this hybrid power gearbox can also be supported stepless
Speed change (eCVT).Therefore, it is possible to improve transmission efficiency, oil consumption is reduced；Moreover, because the transmission ratio of variable speed is continuous,
So that speed change becomes to smooth out very much, comfort is improved.
In the present embodiment, first clutch C1 be reduction gear clutch, second clutch C2 be overgear clutch, first
Brake C3 is low speed/reverse gear brake, and second brake C4 is two grades of brakes.That is, from the first drive shift to
Four drive shifts, gear gradually rise.That is, the first drive shift, the second drive shift have larger transmission ratio, under the gear
Speed is slower；Third drive shift, the 4th drive shift have smaller transmission ratio, the speed under the gear very fast.
The driving force of driving motor M is relatively small, suitable for working under low gear；The driving force of engine is relatively
Greatly, suitable for working under high gear.Therefore, meet design requirement, engine is avoided often to work under low gear, waste
The energy.
Specifically, first clutch C1, second clutch C2 can be multidisc clutch or single disc clutch；First
Brake C3, second brake C4 can be multi-plate brake or one chip brake.
The mode that driving motor M is fixedly connected with the first sun gear P1 can be：Driving motor M includes stator M1 and rotor
M2, rotor M2 are placed in input shaft Z1, can rotate and be fixedly connected with the first sun gear P1 as output end.
Engine is connect with input shaft Z1：It is equipped with connection in the input terminal of input shaft Z1
Part (not shown), connector can be directly fixedly connected with engine, defeated to which the power of engine to be directly passed to
Enter axis Z1；Alternatively, input shaft Z1 input terminal be equipped with third clutch (not shown), third clutch can with start
Machine engages or separation, and when third clutch engages, the power of engine is passed to input shaft Z1.
With continued reference to Fig. 1, the first transmission gear D1 is also set on input shaft Z1, the first transmission gear D1, which is fixed, to be connected
First planet carrier P4 is met, and is connect by bearing with gear box casing K.Simpson hybrid power gearbox further includes output shaft
Z2, is fixed with the second transmission gear D2 on output shaft Z2, and the second transmission gear D2 is meshed with the first transmission gear D1.
Therefore, the rotary power of first planet carrier P4 is transferred to defeated by the first transmission gear D1, the second transmission gear D2
Shaft Z2.Output shaft Z2 is transferred to differential mechanism DF by third transmission gear D3, the 4th transmission gear D4 again, and differential mechanism DF connects
Automotive wheel is connect, to realize the traveling of automobile.
The present invention also provides a kind of automobiles, including above-described Simpson hybrid power gearbox.
Although present disclosure is as above, present invention is not limited to this.Any those skilled in the art are not departing from this
It in the spirit and scope of invention, can make various changes or modifications, therefore protection scope of the present invention should be with claim institute
Subject to the range of restriction.
