Generating tire

Technical field

The present invention relates to a kind of novel energy-saving environment-friendly tire that in motor tire, utilizes piezoeffect to realize self power generation in the running car, be particularly suited in electronlmobil, using.

Technical background

Motor tire is the vitals of automobile, makes wheel and road surface well attached, to guarantee traction property, braking ability and the crossing ability of automobile.It bears whole load of automobile, transmits the tractive force of direct of travel and the power and the moment of other direction, also absorbs gentle bringing from the ground-surface shock and vibration.Most power of driving engine are realized acting through tire, and wherein the considerable part consumption of power causes tire heating and fatigue of material aging in the in-fighting of tire.No matter make a general survey of the developing history of motor tire, be the change of technique of material and structure, for example from the polysulphide rubbers to artificial rubber; From narrow wheel rim to wide wheel rim, from the band tyre to the air-inflation tyre, from the diagonal tyre to the radial-ply tyre; From the textile cord to the steel cord or the like, to improving loading strength, increase the service life; Improve automobile and hold compliance under the arm and take safely, comfortable, all obtain tangible progress to reach.Yet, do not see as yet that so far any technological improvement to the energy that is recovered in loss in the tire, becomes a kind of technical bottleneck.

The objective of the invention is to, propose a kind of technical solution that can partially recycled loss energy in tire, make tire be converted into available electric energy because of the part energy consumption of mechanically deform generating material internal friction.Essence of the present invention is, in tire, rationally adopt have suppress electrical effect functional high molecule material as transformation of energy media and actv. electricity collection method.

Summary of the invention

The structurally similar conventional full-steel radial ply free from inflatable inner tube tire of the present invention; As shown in Figure 1, form by main portions such as crown 3, electric layer 1, tire shoulder 6, sidewall rubber 10, meridian section steel cord 7, bracing ply 4, tyre bead 12, inside liners (or air-retaining liner) 9.

Crown

The crown 3 and the commercially available radial-ply tyre of tire of the present invention are as good as on section form, but material hardness is higher, and purpose is the dependent variable after the tire load-bearing is transferred to and its tight electric layer 1 that joins to greatest extent.

Electric layer

Electric layer 1 is substantive parts of the present invention, and it is the endless belt that inlays between crown and bracing ply, covers on the bracing ply 4 of wire quality, is suppressed the High molecular material PVdF (CH of electrical effect by tool ₂-CF ₂) _nCompacting forms, and after polarization is handled, carries out electric preparation.Electric layer endless belt after the electric preparation is as shown in Figure 2.Among Fig. 2; B representes the electric layer base band through the polarization processing; With the heat pressing process conductive rubber layer of fitting, wherein, a is illustrated in the conductive layers that the base band inner cylinder face all covers on the base band surface; C is illustrated in a plurality of rectangular conductive rubber layers of the mutual electric insulating that base band external cylindrical surface upper edge generatrix direction covered; The conduction that its effect is equivalent on piezoelectric ceramic devices surface metalation layer and the printed wiring board (PCB) is covered the copper layer, and be used as at this and collect the electric charge that piezoeffect produces, and being electrically connected of realization and electronics package.The quantity n of rectangular conductive rubber layer c should confirm in tire design by following principle: after the minimum carrying of tire (automotive dead weight adds a chaufeur body weight), should guarantee that additional strain all takes place the piezoelectric polymeric materials that the rarest rectangular conductive rubber layer is covered.Additional strain is like this definition: tire is under specified inflation pressure, and the whole static strain that takes place of electric layer wherein, the electric layer material of only corresponding tire landing part radially reach the shearing additional strain that produces because of tractive force because of what terrestrial attraction produced.Additional strain is the necessary condition that reclaims electric energy.In running car, additional strain produces in the piezoelectric that each rectangular conductive layer covers along tire circumferential direction successively.

Electrical principle

Along with the generation of additional strain, piezoelectric polymeric materials is at the opposite electric charge of cooresponding conductive rubber laminar surface polarization (wherein electric layer inside face single-piece conductive rubber overplate is shared pole plate).In view of during automobile advances, produce the piezoelectric samsara conversion of additional strain, for the cooresponding that part of piezoelectric of arbitrary rectangular conductive layer of electric layer outside face; All account for 1/n in the cycle and additional strain takes place in the period, promptly be turned back to when grabbing destination location when a certain section piezoelectric, take place earlier radially and the positive additional strain in tangential from producing to the process that disappears at wheel revolutions; With wheel; This part material additional strain disappears, that is takes place radially to bear additional strain with the tangential thereupon, and the electric dipole that both produce is in the opposite direction; As can not handle in real time; Charge neutralization will take place, even exist the mechanical energy that takes place because of piezoeffect to arrive the switching process of electric energy, also making collectable electric energy total amount is zero.In order effectively to collect electric energy, in the tire of the present invention, in electric layer, inlay n by the sub-d of bonded assembly biphase rectification shown in Figure 2.Commufafor is customised soft packaged type, is connected with being convenient to reduce volume.1. and 3. the input end of each commufafor d connects inside and outside conductive rubber layer to electric layer respectively, and (wherein 1. input end connects to corresponding rectangular conductive rubber layer; 3. input end connect to electric layer inside face conductive rubber layer publicly); The commufafor mouth 2., 4. connect to automobile batteries 19 as the electricity collection end is realized the charging to battery publicly.Analyze the current path of commufafor to battery charge; Can know that there are recessive logical AND gate in each commufafor mouth and being connected of battery; Every section electric energy that the High molecular material generation of additional strain takes place is independently contributed to battery charge, charge neutralization does not take place therebetween, prevent the electric energy in-fighting.

Lead 2 is the public cathode output end of commufafor among Fig. 1, draws and be connected to the insulator part that is installed on the wheel rim 13 through tire sidewall.As shown in Figure 1, insulator part is made up of threaded matrix 16, locknut 14, sealing rubber ring 15, insulating glass body 17 and Ke Fa alloy terminals 18, when tire is packed wheel rim into, should make lead 2 aim at insulator parts as far as possible, and welding.The public cathode output end of commufafor is drawn (in Fig. 1, lead 5 expressions overlap with lead 2) with the mode of similar lead 2 from tire, but need not pass through insulator, can directly be welded on (being minus earth) on the wheel rim.For reducing the wheel static unbalance that causes because of the electric energy output lead, the positive and negative electrode lead-in wire of lead 2 and 5 representatives should be in the layout of the tire circumference offside.

Other part of tire of the present invention; Like tire shoulder 6, sidewall 10, meridian section steel cord 7, bracing ply 4, tyre bead 12 and parcel rubber 11, tire inwall rubber layer 8 and inside liner (or air-retaining liner) 9 etc., can abide by the design regulation of existing whole steel wire radial tyre fully at aspects such as structure, selection and principles of design.
