Abstract
This invention relates to a car oil saving method including: when the rotation speed of an engine is higher than that of a shaft of the gear-box, the engine transfers kinetic energy to a shaft of the gear-box via the driving unit characterizing that when the rotate speed of the engine is lower than that of a shaft of the gear-box, the kinetic energy of the shaft of the gear-box will not be transferred to the engine to save fuel oil and reduce wearing of the engine.
Description
Technical field:
The present invention relates to a kind of vehicle oil-saving method.
Background technology:
Usually automotive engine rotates along a direction, when vehicle starting in the running all the time, the power of driving engine is given change speed gear box by clutch transmits, change gear by the pilot control change speed gear box by the different speed of a motor vehicle again, drive drive axle, the drive wheels rotation is advanced automobile or is retreated.Automobile when chaufeur refuels, passes through fuel oil with driving engine in the process of moving, and the power that burning produces drives whole locomotive body by power-transfer clutch, change speed gear box, drive axle, and the car body of generation motion has also had certain force of inertia, and inertia moves forward it.When chaufeur need be received oil, reduce or stop to engine oil, engine revolution reduces, at this moment car body inertia power forces to drive engine rotation by drive axle, change speed gear box, power-transfer clutch, automobile still relies on its inertia to advance forward, but because the force of inertia of car body will force to drive drive axle, change speed gear box, power-transfer clutch, engine rotation, and cause unnecessary degradation of energy (is that driving engine is when non-refuelling, it is exactly an inflation pump, want to allow its rotate, just need very big mechanical energy to drive it).
Summary of the invention:
The problem to be solved in the present invention provides a kind of vehicle oil-saving method, can effectively avoid the unnecessary energy dissipation that causes when automobile is received oil.Technical scheme: a kind of vehicle oil-saving method, when the rotating speed of driving engine is higher than the rotating speed of one of change speed gear box, driving engine passes to one of change speed gear box by transmission device with kinetic energy, it is characterized in that: when the rotating speed of driving engine is lower than the rotating speed of one of change speed gear box, make the kinetic energy of one of change speed gear box not pass to driving engine; On one of change speed gear box, unidirectional engaging device is housed, unidirectional engaging device can be driven by the power transmission sheet of power-transfer clutch or engine flywheel drives, make when the rotating speed of driving engine is lower than the rotating speed of one of change speed gear box, make the kinetic energy of one of change speed gear box not pass to driving engine; Said unidirectional engaging device structure is, has initiatively unidirectional interlock overcoat, initiatively be provided with passive interlock inner spline housing in the unidirectional interlock overcoat, the outside in passive interlock inner spline housing cross section is a polygon, be provided with the long pearl of matching with the passive interlock inner spline housing outside between passive interlock inner spline housing and the unidirectional interlock overcoat of active, long pearl is installed on the long pearl frame.Beneficial effect: the invention enables and have only driving engine to transmit mechanical energy, and change speed gear box can not back transfer mechanical energy to change speed gear box.When chaufeur was received oil, driving engine entered idling mode at once, and automobile also drives engine rotation no longer by force, but this part inertia force is used, and drove running car.The present invention can fuel-economizing 25%-30%, do not influence the power of automobile, do not influence the speed of automobile, to reach the purpose that saving fuel oil reduces engine wear, the service life of yet having improved driving engine yet.
Description of drawings:
Fig. 1 is the used unidirectional engaging device structural representation of the present invention;
Fig. 2 is the side sectional view of Fig. 1.
The specific embodiment:
When the rotating speed of driving engine is lower than the rotating speed of one of change speed gear box, make the kinetic energy of one of change speed gear box not pass to driving engine, in the present embodiment, realize by unidirectional engaging device.Unidirectional engaging device is contained on one of the change speed gear box, and unidirectional engaging device can be driven by the power transmission sheet of power-transfer clutch or engine flywheel drives.As shown in Figure 1 and Figure 2, unidirectional engaging device has initiatively unidirectional interlock overcoat 2, initiatively be provided with passive interlock inner spline housing 5 in the unidirectional interlock overcoat, the outside in passive interlock inner spline housing cross section is the polygon inclined-plane, be provided with the long pearl 1 of matching with the passive interlock inner spline housing outside between passive interlock inner spline housing 5 and the unidirectional interlock overcoat 2 of active, long pearl is installed on the long pearl frame 3.Between long pearl frame and the passive interlock inner spline housing spring 4 is housed.Unidirectional interlock overcoat 2 initiatively is installed on the power transmission sheet 7 between the power-transfer clutch 6, and passive interlock inner spline housing 5 is enclosed within on one of the change speed gear box.
When chaufeur refuels, engine speed increases, flywheel drives clutch segment, power transmission sheet 7 drives initiatively unidirectional interlock overcoat 2, at this moment, the rotating speed of driving engine is higher than rotating speed of change speed gear box, initiatively the rotating speed of unidirectional interlock overcoat 2 is higher than the rotating speed of passive interlock inner spline housing 5, long pearl 1 is along the inclined-plane clickwise in passive interlock inner spline housing 5 outsides, and when long pearl was rolled into the highest point on inclined-plane, long pearl 1 can not upwards be rolled again, because it is very close to each other again, make the long pearl 1 of initiatively unidirectional interlock overcoat 2 usefulness block passive interlock inner spline housing 5, at this moment interior overcoat becomes one, and makes the kinetic energy of driving engine pass to one of change speed gear box.Chaufeur is received oil, engine speed descends, the rotating speed of driving engine is lower than one of change speed gear box, initiatively the rotating speed of unidirectional interlock overcoat 2 is lower than the rotating speed of passive interlock inner spline housing 5, one of change speed gear box drives passive interlock inner spline housing 5 rotations, because the rotating speed of interior cover is higher than overcoat, long pearl 1 has rolled from the inclined-plane highest point, cause long pearl 1 and initiatively unidirectional interlock overcoat 2 to break away from, kinetic energy of change speed gear box does not pass to driving engine, the rotator inertia of automobile is slided, no longer drive driving engine and force rotation, thereby reach the purpose of saving the energy.
