The specific embodiment
Below in conjunction with accompanying drawing 1-4 preferred embodiment of the present invention is described in detail, thereby protection scope of the present invention is made more explicit defining so that advantages and features of the invention can be easier to be those skilled in the art will recognize that.
The power system structure of extended-range hybrid vehicle proposed by the invention as shown in Figure 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 pinion carrier 3 of planet circular system, second motor 2 is connected with the sun wheel 4 of planet circular system, the ring inner gear 5 of planet circular system can be connected with casing by first magnetic clutch 8, also can link to each other with first motor output shaft 12 by second magnetic clutch 9.First motor output shaft 12 links to each other with the input shaft of automobile main 13.The power system of the extended-range hybrid vehicle of being invented has three operational modes, and its principle of work is as described below:
Electric-only mode:
Under this pattern, the driving engine 6 and second motor 2 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 as shown in Figure 2.
As the final ratio behind first motor output shaft 12 be
, then the pass between moment and the rotating speed is between the drive wheel and first motor 1:
Herein,
With
Be the rotating speed and the moment of first motor 1,
With
Rotating speed and moment for drive wheel.
Series hybrid mode:
Under this pattern, first magnetic clutch, 8 closures, second magnetic clutch 9 is open.Because first magnetic clutch, 8 closures, the ring inner gear 5 of planet circular system is fixed on the casing.When automobile entered this operational mode, driving engine 6 was at first started by second motor 2.Driving engine 6 drives 2 generatings of second motor by planet circular system then.The electric power that is sent can direct drive first motor 1 drive or give battery 7 chargings.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 as shown in Figure 3.
Motor under this pattern, driving engine exists following rotating speed and moment relation between the drive wheel:
Herein,
,
With
Be respectively wheel, driving engine 6 and pinion carrier 3 rotating speeds,
,
With
Be respectively second motor 2, driving engine 6 and wheel torque,
Be the satellite gear parameter, it equals to encircle the number of teeth of inner gear 5 divided by sun wheel 4 numbers of teeth.
The mixed mode that mixes in parallel:
Under this pattern, first magnetic clutch 8 is open, second magnetic clutch, 9 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 as shown in Figure 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:
Operational mode is switched:
For convenience of description, now electric-only mode is defined as pattern one, series hybrid mode is defined as pattern two, and hybrid mode is defined as pattern three side by side.
According to different operating modes and battery 7 charge volumes, automobile switches between three patterns.Switch as described below between three kinds of patterns.
Pattern one → pattern two: when automobile moves in pattern one, driving engine 6, the second motors 2, the satellite gear of planet circular system is static.Because of satellite gear has two degree of freedom, first magnetic clutch 8 pulsation-free easily engages.After first magnetic clutch 8 engaged, second motor, 2 first start the engines 6 entered pattern two operations then.
Pattern two → pattern three: when pattern two switches to pattern three, first magnetic clutch 8 is broken away from, make the rotating speed at second magnetic clutch, 9 two ends reach synchronously by the rotating speed of controlling second motor 2 then after, again with second magnetic clutch, 9 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 first magnetic clutch 8 is separated, driving engine 6 is flame-out, and 2 outages of second motor get final product.
Pattern three → pattern one: only need second magnetic clutch 9 is separated, driving engine 6 is flame-out, and 2 outages of second motor get final product.
Pattern three → pattern two: at first second magnetic clutch 9 is separated, to make the rotating speed of the ring inner gear 5 of planet circular system be zero by controlling second motor, 2 rotating speeds then, makes first magnetic clutch 8 not have the steady combination of impact then.
Various as mentioned above 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 stroke about 100 kilometers according to designing requirement, the power system of this kind extended-range 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).
More than the power system structure of extended-range hybrid vehicle that the present invention is proposed carried out detailed technology elaboration with principle and embodiment.Clearly, on the basis of not leaving scope and spirit of the present invention, can make amendment to existing invention (comprising technical matters).In the technical field of the invention, a GPRS technical minimum just can carry out various changes in technology main idea scope of the present invention.
