The specific embodiment
Embodiment to the utility model is elaborated below in conjunction with accompanying drawing, but the multitude of different ways that the utility model can be defined by the claims and cover is implemented.
Referring to Fig. 1; A kind of hybrid power transmission module, the planetary mechanism 4 that comprises motor 1, driving engine 2, is connected with driving engine 2 with motor 1, with planetary mechanism 4 bonded assembly stepless speed changing mechanisms 3, with stepless speed changing mechanism 3 bonded assembly speed reduction gearings 15 and with speed reduction gearing 15 bonded assembly output shafts 16.The power of motor 1, driving engine 2 outputs is through after planetary structure 4, stepless speed changing mechanism 3, the speed reduction gearing 15, through output shaft 16 outputs.
Motor 1 is integrated in the CVT toric transmission, and motor 1 is connected with a motor power output shaft 101.This motor power output shaft 101 and pinion carrier 8 are connected through spline, so that drive pinion carrier 8 motions.Concrete, be connected through spline with first end of motor power output shaft 101 after the sub-stent extension of pinion carrier 8 and the bending.This hybrid power module is introduced motor 1, has cancelled the turbine transformer of traditional C VT, and motor 1 is installed in the position of the turbine transformer of traditional C VT, does not account for installing space in addition, and structure is more compact.Like this; The power of motor 1 output can be directly passed to pinion carrier 8 through motor power output shaft 101; Because the rotating speed of motor 1 can increase from zero gradually, so being provided with of motor 1 can avoid driving engine to be under the low speed situation at high revolution, vehicle, and engine speed and car speed mismatch; Cause and drag shelves, and waste energy.
Driving engine 2 is installed in the front end of CVT toric transmission, and driving engine 2 is connected with an engine power output shaft 201, and engine power output shaft 201 is connected with the wheel shaft of sun wheel 7, and extends to power-transfer clutch 9, captives joint with power-transfer clutch 9.Like this, the power of driving engine output passes to sun wheel 7 through engine power output shaft 201, can also pass to pinion carrier 8 through power-transfer clutch 9.In other embodiments, the integrated member that is formed in one of the wheel shaft of engine power output shaft 201 and sun wheel 7.
In conjunction with referring to Fig. 2, stepless speed changing mechanism 3 comprises driving pulley axle assembly 12, metal tape 13 and passive belt axle aggregate 14, and driving pulley axle assembly 12 is connected with passive belt axle aggregate 14 through metal tape 13.Wherein, the wheel shaft 121 of driving pulley axle assembly 12 stretches out with pinion carrier 8 and is connected through spline, as the power intake of stepless speed changing mechanism 3.Wherein, the wheel shaft of passive belt axle aggregate 14 stretches out with speed reduction gearing 15 and is connected, as the clutch end of stepless speed changing mechanism.
This hybrid power transmission module also comprises hydraulic valve block 17, fil 18, oil pump 19 and Oil pump electrical machinery 20, and this oil pump 19 is by Oil pump electrical machinery 20 individual drive, need not driving engine or motor 1 provides power for oil pump.
In conjunction with referring to Fig. 3, planetary mechanism 4 comprises the expert star-wheel of sun wheel 7, a group 6, one group of layman's star-wheel 5, pinion carrier 8, gear ring 11, power-transfer clutch 9 and drg 10.Wherein, sun wheel 7 is in the center of planetary mechanism 4, and promptly the wheel shaft of sun wheel 7 also is planetary mechanism 4 S. A.s.Sun wheel 7 is installed on the mouth of engine power input shaft 201.Expert star-wheel 6, layman's star-wheel 5 all are installed on pinion carrier 8, and sun wheel 7, expert star-wheel 6, layman's star-wheel 5 and gear ring 11 are connected with a joggle successively.Wherein, drg 10 comprises two groups of friction linings, and two groups of friction linings are individually fixed in the housing and the gear ring 11 of change-speed box.Wherein, power-transfer clutch 9 comprises two groups of friction linings, and two groups of friction linings are individually fixed in sun wheel 7 and pinion carrier 8.
The synthetic process of the transmission of power of this hybrid power transmission module and power is:
When power-transfer clutch 9 all separated with drg 10, this power transmission module was in electric-only mode, and promptly driving engine 2 is in and shuts down or idling conditions, and motor 1 is in "on" position.The power of motor 1 output is directly passed to stepless speed changing mechanism 3 through motor power output shaft 101, pinion carrier 8, and at this moment motor 1 individual drive vehicle advances or retreats.Electric-only mode is applicable to that vehicle is slow in the speed of a motor vehicle, needs the less operation phase of power.
When power-transfer clutch 9 joints, when drg 10 does not engage, driving engine 2 is in running order, and driving engine 2 outputting powers pass to sun wheel 7 and power-transfer clutch 9 through engine power output shaft 201.At this moment, if motor 1 energising, then motor power also passes to pinion carrier 8 through motor power output shaft 101, and planetary mechanism 4 unitary rotation are hybrid mode.If motor 1 no power then is pure engine drive pattern, at this moment, the power of driving engine 2 outputs is given the battery charge of motor 1 simultaneously.
When drg 10 joints, when power-transfer clutch 9 does not engage, pinion carrier 8 is in the mode of operation of counter-rotating, is reverse gear mode.At this moment, if motor 1 energising, motor 1 also is in reversing mode, and then whole transmission module is the hybrid power reverse gear mode; If ISG motor 1 no power then is pure driving engine reverse gear mode.
Therefore; Whole power transmission module can perhaps separate to come synthesized-power through the joint of power-transfer clutch 9 and drg 10; When car speed is in low speed and slowly moves, particularly on starting stage or urban highway, during crowded traffic, only need to use the power of motor 1 to get final product; Realize electric-only mode through cut-off clutch 9 and drg 10 this moment; When vehicle is in fair speed operation, and road conditions use engine output power separately when allowing to move at a relatively high speed, and promptly power-transfer clutch 9 engages, and disable motor 1 is realized pure engine drive pattern this moment; When vehicle was in lasting high-speed cruising or climbing or acceleration phase, the situation of under power may appear in pure engine drive, at this moment; Power-transfer clutch 9 engages, and motor 1 energising, then realizes driving engine and motor 1 hybrid mode of outputting power simultaneously; Motor 1 can effectively replenish power; Realize the steady high-speed cruising of vehicle, the power abundance of perhaps climbing is perhaps quickened smooth and easy.
As additional embodiments, the utility model provides a kind of hybrid vehicle, comprises the power transmission module, and the power transmission module is above-mentioned hybrid power transmission module.
The hybrid power transmission module of the utility model is applicable to preposition forerunner's type vehicle and preposition rear-guard type vehicle.Referring to Fig. 1, vertical and during with planetary structure 4 horizontally sets, be applicable to preposition forerunner's type vehicle with stepless speed changing mechanism 3 when output shaft 16 and engine power output shaft 201.Referring to Fig. 2,, when perhaps being arranged on the same straight line, be applicable to preposition rear-guard type vehicle when output shaft 16 and engine power output shaft 201 laterally arrange.
The preferred embodiment that the above is merely the utility model is not limited to the utility model, and for a person skilled in the art, the utility model can have various changes and variation.All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
