The specific embodiment
Set forth preferred embodiment of the present invention below in conjunction with accompanying drawing 1-4 in detail
; Thereby protection scope of the present invention is made more explicit defining so that advantage of the present invention and characteristic can be easier to those skilled in the art will recognize that.
The power system structure of the hybrid vehicle that
are proposed by the invention is shown in accompanying drawing 1.This system comprises a driving engine 6, the first motors 1 and 2, one planet circular systems of second motor, first magnetic clutch 8 and second magnetic clutch, 9, one Battery packs 7 and drive electronic system (being inverter 10).Driving engine 6 is connected with the ring inner gear 5 of planet circular system; First motor 1 is connected with the sun wheel 4 of planet circular system through sleeve 11; The pinion carrier 3 of planet circular system can be connected with casing through second magnetic clutch 9, also can link to each other with second motor output shaft 12 through first magnetic clutch 8.Second motor output shaft 12 links to each other with the input shaft of main 13.
structure shown in accompanying drawing 1 is fit to f-w-d, back-wheel drive and four wheel drive.The different driving system is that mouth further part shown in the accompanying drawing 1 is different.The power system principle of work of the hybrid vehicle of being invented is as described below.
Electric-only mode:
Under this pattern, the driving engine 6 and first motor 1 are closed
.First magnetic clutch 8 and second magnetic clutch 9 all are in open state.This mode adaptive vehicle starting, reversing, low cruise and cruising condition.Suitable speed range is about-30 kilometers/hour to 50 kilometers/hour, 0 to 30 kilowatt of power demand scope.This pattern power is all provided by battery 7, and its power transmission line is shown in accompanying drawing 2.
Final ratio as behind second motor output shaft 12 does
, then the relation between moment and the rotating speed is between the drive wheel and second motor 2:
Here, 
With
Be the rotating speed and the moment of second motor 2,
With
Rotating speed and moment for drive wheel.
Series hybrid mode:
under this pattern, second magnetic clutch, 9 closures, first magnetic clutch 8 is open.Because second magnetic clutch, 9 closures, the pinion carrier 3 of planet circular system is fixed on the casing.When automobile got into this operational mode, driving engine 6 was at first started by first motor 1.Driving engine 6 drives 1 generating of first motor through planet circular system then.The electric power that is sent can be driven or charge the battery by direct drive second motor 2.This pattern is fit to speed range and is approximately 0 ~ 50 kilometer/hour, and power range is for being approximately 30 ~ 50Kw.
The power transmission line of
this pattern is shown in accompanying drawing 3.
First motor, 1, the second motor 2 under this pattern, driving engine 6 exists following rotating speed and moment relation between the drive wheel:
Here, 
,
Be respectively driving engine 6 and ring inner gear 5 rotating speeds,
,
Be respectively the moment of torsion of first motor 1 and driving engine 6,
Be the satellite gear parameter, it equals to encircle inner gear 5 numbers of teeth divided by sun wheel 4 numbers of teeth.
Parallel connection mixed pattern:
under this pattern, second magnetic clutch 9 is open, first magnetic clutch, 8 closures.This pattern is fit to the high power requirements operating mode, and the suitable speed range of institute is greater than 50 kilometers/hour, and the power demand scope is more than 50 kilowatts.Power transmission line is shown in accompanying drawing 4 under this pattern.
Under this pattern, driving engine 6, the first motors 1 and second motor 2 exist following rotating speed and moment of torsion relation between the drive wheel:
The switching of operational mode:
According to different operating modes and battery charge amount, automobile switches between three patterns
.For describing conveniently, electric-only mode is defined as pattern one at present, series hybrid mode is defined as pattern two, and parallelly connected mixed mode-definition is a pattern three.
Switch as described below between three kinds of patterns:
pattern one → pattern two: when automobile moves in pattern one, driving engine 6, the first motors 1, satellite gear remains static.Because of planet circular system has two degree of freedom, second magnetic clutch 9 pulsation-free easily engages.After second magnetic clutch 9 engaged, first motor, 1 first start the engine 6 got into pattern two operations then.
pattern two → pattern three: when pattern two switches to pattern three; Second magnetic clutch 9 is broken away from; After making the rotating speed at first magnetic clutch, 8 two ends reach synchronously through the rotating speed of controlling first motor 1 then, again with first magnetic clutch, 8 closures.So just can implementation pattern two steadily switching efficiently to pattern three.
pattern one → pattern three: under vehicle control unit controls, automobile switches to pattern two from pattern one earlier, and then switches to pattern three from pattern two.
pattern two → pattern one: only need second magnetic clutch 9 is separated, driving engine 6 is flame-out, and 1 outage of first motor gets final product.
pattern three → pattern one: only need first magnetic clutch 8 is separated, driving engine 6 is flame-out, and 1 outage of first motor gets final product.
pattern three → pattern two: at first first magnetic clutch 8 is separated, to make pinion carrier 3 and rotating speed be zero through controlling first motor, 1 rotating speed then, makes second magnetic clutch 9 not have to impact steadily then and combine.
various as stated patterns are selected according to vehicle behavior and battery 7 charge volumes, to reach dynamic property, traveling comfort, low energy consumption, the Optimization result of anti-emission carburetor.Because electric-only mode can reach the stroke about 100 kilometers according to designing requirement; The power system of this kind hybrid vehicle can guarantee pure electric operation under most of situations; Extended-range operation in case of necessity; Thereby realize convenience to the full extent; Low energy consumption, zero-emission (or minimum discharging).
The power system structure of the hybrid vehicle that more than
the present invention is proposed and principle and embodiment have been carried out detailed technology and have been set forth.Clearly, on the basis of not leaving scope of the present invention and spirit, can make amendment to existing invention (comprising technical matters); Technical field under the present invention; GPRS technical minimum just can carry out various changes in technology main idea scope of the present invention.
