Description

Safe and efficient wheel

This case is division, original application day 2003.1.1, application number 03101364.3, title " safe and efficient tire ".For the number of dividing an application 201110234933.3, title " automobile-used wheel and weighting material safely and efficiently ".

One, technical field: the invention belongs to traffic and transport field, especially the safe and efficient tire of the vehicle.

Two, background technology: known tire has the following disadvantages:

1, poor stability.Tire is in operation and can blows out, and especially front-wheel tyre-burst, accidents caused continuous thus, often causes the heavy losses of lives and properties, and this problem does not obtain fine solution always.The reason of blowing out has the foreign matter cutting, the tire temperature is too high, tire pressure is too high, tire self insufficient strength, and tire construction is unreasonable etc.One of reason of tire temperature rise be the gas of filling in tire be under pressure and pressure constantly changes and constantly compressional movement process in produce high temperature.And gas is the bad conductor of heat, and heat can not finely distribute, and is accumulated into high temperature.High temperature makes gas expansion in tire, produces high pressure, causes blowing out.As seen, gas conduction is poor, and easily giving birth to high temperature is the major cause of blowing out.Because charges are gas, when blowing out, the diameter of accident tire sharply reduces, rotating speed sharply reduces, and the distance of going in the same time sharply reduces, and makes the vehicle, as automobile respectively to take turns range ability inconsistent, be the hard-over campaign in the center of circle thereby make car occur to blow out, the driver has little time to process, and causes meeting accident to lose control of one's vehicle.It is the key reason that meets accident that diameter of tyres diminishes.

2, efficient is not high.Efficient refers to tire in use, the work capacity of completing in the unit time.Also refer to useful work shared percentum in total work.Such as motor tire, in the situation that other conditions are identical, the tire of sufficient gas is higher than the tire efficient of deficency.It is the capable distance of unit energy.The reason that efficient is not high has many, and one of reason is that tire inner stuffing performance inconsistency is suitable.Known tire inner stuffing is air.The molecular structure of air is very loose, easily compressed, change volume.And before being pressed into liquid, its volume always is in labile state.Like this, after filling pressure air in tire, due to the mutability of volume of air, make the diameter of tire always be in unsteady state.Inflation pressure is excessive, again fragile inside and outside tire.Such as automobile, during load, its tire the radius that is located in and can be shortened.In fact, most motor tire and is located in radius and can shortens when load.And the radius of tire except the below do not shorten, and be elongated to some extent due to the increase of pressure on the contrary.Like this, the wheel in motion always will overcome resistance and advance, or even improves constantly whole center of gravity and move.Because being positioned at wheel the radius of wheel that is located in the front and half path length that is located in than wheel.So just produce a large amount of useless power consumption, reduced efficient.Due to the load force of gas poor (for liquid, solid), so tire must be made very greatly, could satisfy the carrying demand again.This just causes the waste of material, work, and has increased weight, increases energy consumption.

3, tire material poor performance.The material of inside and outside tire is rubber, and the air-tightness of rubber is not fine, and the pressure of inflation is larger, and temperature is higher, and its air-tightness is poorer.The original very high tire of pressure has just become flat soon, and poor air-tightness is major cause.The drawback of poor air-tightness shows and makes the frequent deficency of tire, and air pressure is not enough, causes tire being located in radius shortening, and produces very large resistance for the tire in motion, the waste energy.The tyre rim of the steel ring of tire, especially automobile, trac. is made with steel plate, has both increased the car deadweight, easily gets rusty again, also is difficult for processing, and cost is high.Known technology only bicycle adopts the plastics steel ring, other cars such as self-propelled vehicle, and the manpower wooden handcart does not adopt.A kind of known rickshaw solid rubber tyre is arranged, poor flexibility, bearing capacity is poor, and cost is high.

4, tire shape unreasonable structure.From cross-sectional plane, the circular configuration of cover tire inner chamber and the arc-shaped structure of appearance are unfavorable for tire below, namely be located in, keep radius constant.Such as automobile, need tire certain area that lands to be arranged with carrying after load, the total pressure of the area that lands of all wheels equals the total weight of car self and load.Be shaped as circular arc inside and outside known cover tire cross-sectional plane, outside face is more obvious after inflation, and tire be located in becomes a sphere, a ball point, rather than a line.During load, this ball point is because the area that lands is little, and pressure is large, only has contracting inwards, has so just become a plane, and tire the radius that is located in and therefore shortened, and produces aforesaid resistance of motion.As seen, the arc-shaped structure of inner chamber and profile on the tire cross-sectional plane can not form the actv. support to tire, can not make tire be located in and form a line.Theoretically, only have when wheel be located in when being an axial line, the motion of tire is the most laborsaving.Because tire the radius that is located in and was not shortened or shorten minimum this moment.As long as radius one shortens, just become a face, the landing ground identical with ground shape.Landing ground is larger, and radius is shorter, more waste energy.

5, the rubbery cover tyre dual-side is too high.Cover tire has the tripartite, the side and the dual-side that land.The cover tire dual-side is too high, has both wasted elastomeric material, is unfavorable for that again tire is keeping being located in radius constant.When tyre load, outer swollen distortion easily occurs in dual-side, must cause tire being located in radius shortening, and forms resistance of motion.

6, cost is high.The one, the cover tire landing ground is with after old, and often dual-side is not bad, and result has but abandoned together.Earth resources is formed waste, also contaminated environment.Old tire renovation poor performance, dangerous, inconvenience, cost is high.The 2nd, due to aforesaid background technology, easily cause damaged tyres, thereby cost is high.

Known technology injects a kind of automatic mending tyre liquid in tire, automatic tire patching when aperture leaks gas.Some water in this tyre repairing fluid composition.The general tyre repairing fluid of tire internal volume below 1/3 that only inject.96101135.1 patent application is a kind of water filling tyre, method is to inject the water of tire internal volume below 1/3 in tire, and purpose is to utilize the water on the go to produce inertial energy-saving.Above-mentioned technology can not solve the deficiency that tire exists.Known tyre needs often inflation, and is to guarantee air pressure, therefore inconvenient.Due to complex structure, install, dismantle, keep in repair all inconvenient again.

The deficiency of known technology also will further illustrate in conjunction with particular content in the back.

Three, summary of the invention: the objective of the invention is to solve the problems referred to above of known tyre, make it safety, efficient.

1, change charges.The present invention is at wheel tyre cavity fill liquid, but back under pressure.Be filled to more than 1/3 of volume, until sufficient.Or liquid is full of the wheel space of tyre cavity except the solid filling thing.The liquid of wheel tyre cavity plays the carrying effect.That charges can be is liquid, paste body shape, colloidal.Perhaps, charges are solid, liquid, or solid, liquid, the composite of gas, compound.Or charges are the critical mass state between solid, liquid, gas.As semifluid.Or charges are that the aggregation of powdery, granular solids is or/and binder.Expanded material also is as foamed plastic, foamed rubber.Liquid can be water, or the compound of water and other materials or hydrate.Also compound or the compound of oil or oil and other materials.Therefore this tire can be apneustic full closeding state, solid state owing to being not easy leakage.Can insert when the fit a tyre as the paste charges, extruding forms filling pressure with carrying by clamping plate, and this tire can be solid shape, also has foam inner tube also can be solid shape, and they all can be without valve.The solid filling thing can be that the present invention is with the inner support of addressing.Filling is namely filled.Liquids and gases are all fluids, observe same fluid rule, and the damping of gas and carrying effect finally will realize by elasticity and the intensity of cover tire, and on this meaning, liquid or gas can obtain same damping and carrying effect as the tire charges.The size of tire capacity is decided by ply rating and area of thrust surface, in the situation that these two conditions are constant, spatial placement solid filling thing, do not affect the tire effect in tire, and can play the supporting role after blowing out.Supporting role is also with aftermentioned.As the tire charges, than gas filling thing, many advantages are arranged with liquid or solid or its composite.The one, the water tightness of rubber, plastics is better than air-tightness, and the moisture subchain is tightr, more solid in conjunction with getting than gas strand, not fugacity.So just reduced the trouble of frequent inflation, and can keep tire to be located in radius constant, reduce resistance of motion.The 2nd, be difficult for blowing out, the permeability of heat of liquid is stronger than gas, and heat production is poorer than gas, in this sample tire, temperature just is difficult for raising, being difficult for expanding, and can therefore not produce high pressure tire is burst and mis-use breakdown.The 3rd, even blow out, liquid, lotion, solid can not resemble to be rushed out gas quickly entirely, causes flat tire, leads to a disaster.Still can exercise after blowing out, until repair.Even can not blow out.The 4th, because solid, liquid or viscid bearing capacity are strong, thereby can reduce the volume of tire, alleviate the weight of tire, improve efficiency, reduce costs.In tire of the present invention, liquid is different from the effect of liquid in known tire, and in known tire, liquid effects is tire patching or plays effect of inertia.The present invention but also has carrying, heat transfer, safety, synergistic effect.Role is different, and the quantity in tire is different, and its material composition is also different.Due to the incompressibility of liquid, thus also atmospheric pressure state of liquid in tire, but still can play the carrying effect.Normal pressure refers to equate with bar pressure, and namely the tire external and internal pressure equates.During in liquid, the liquid in tire has had pressure, becomes pressure fluid when the elastic reaction of cover tire.Due to liquid, lotion, colloid have with gas like or identical dimensional instability and the elasticity under closed state, so can replace gas as the tire charges.And has the unexistent plurality of advantages of gas.In known tire, liquid is only below 1/3 or 1/3, and the present invention can more than 1/3, have living space until be full of in tire.At realm of nature, solid, liquid, gas do not have boundary completely, and therefore, charges of the present invention can be also the critical mass states of solid, liquid, gas.Solid powder/particle is flocked together, be closed in and make charges in tire, also can play the effect of flowing material.Because thinner solid powder/particle also has flowing power, can produce local deformation, such as recessed inwards, and transmission of pressure.Under the state of sealing, can have enough elasticity equally.The mode of assembling can be used liquid adhesive, forms colloid.Be with the elastomeric solid also can be separately as charges in tire.As foam, foamed plastic, bipeltate.The foam charges are equivalent to the inner tube of a tyre, can combine with cover tire, on its cross section, combination interface are arranged.At ice up in winter, can add other materials to form compound or the hydrate of water for waterproof in water.Use instead oil or oil compound or compound.This charges also can be used on non-season in winter or other places certainly.Charges are compound or the compound of other materials beyond water, oil also.In charges (as liquid), various additives can be arranged, as leak preventer, maintaining agent, anti-freeze additive, anti fouling composition etc.The tire of different purposes can have the charges of different performance.Owing to being difficult for leaking, so tire can be apneustic, i.e. aerating midway, primary filling, the lifelong use.If with after plastic sealing layer in the tire of addressing is combined better, select the scope of charges can be wider.This will facilitate use widely, raise the efficiency.

2, deeply enclose shallow tire.Be dark steel ring, shallow cover tire.Shallow cover tire comprises the tabular cover tire.The volume of known tyre, almost entirely in rubbery cover tyre, what have has seldom a volume in steel ring, only account for below 1/3 of whole tire total volume.Steel ring does not encase the cover tire except the rim of the mouth.Tire capacity refers to the inner space of tire, and namely cover tire and steel ring be in conjunction with space in formed tire, is used for the filling material, supports the volume of cover tire and supports the elasticity of cover tire.Known cover tire has the tripartite, and dual-side and bottom surface, bottom surface are periphery.Its dual-side is very high, and purpose is to form the space that holds charges.The cover tire that side is high has many deficiencies.The one, yielding.We also obtain its harm in the benefit that obtains the rubbery cover tyre good springiness, the same good springiness of dual-side of Here it is cover tire, and good springiness is just yielding.When the cover tire load, due to the round property of becoming of fluid, dual-side is namely outwardly, make tire the radius that is located in shorten, form resistance of motion.The 2nd, when blowing out, cover tire loses tire inner support thing, and the dual-side of rubber tyre can't bear weight, flat immediately gets off, and forms accident causation.The 3rd, cost is high, and the very high both many consumption of rubber of dual-side increase again difficulty of processing.

The present invention deepens the dual-side that steel ring replaces or encase cover tire, forms the inner cavity chamber of tire, i.e. the tire internal volume.Only have a small amount of volume on cover tire or there is no volume.Just in time that known technology is reversed.Steel ring also can be the clamping plate shape, and two clamping plate are clamped cover tire from dual-side.Clamping plate also can be large, little on one side on one side.But the second splint weld together, also available bolt or collar are fixed-type.During installation, can first put cover tire, then with clamping plate, cover tire be clamped, be fixed on steel ring.Like this, overcome the deficiency that known technology is difficult for dress, tears open.The steel ring dual-side replaces or the dual-side that encases cover tire has following effect, and the one, cover tire can't be out of shape, tire and is located in radius and does not shorten.It is relative not shortening, and for known cover tire shortened a lot, the present invention did not shorten.Theoretically, all deformation can occur after any material is stressed, just amount varies in size.In fact, also can be out of shape after tire force of the present invention, tire the radius that is located in and also can be shortened, and just for known technology, the amount that shortens is much smaller, thereby reaches purpose safely and efficiently.The 2nd, when blowing out, because steel ring has encased the cover tire dual-side, the degree that encases (or claiming clamping) has reached the over half of known cover tire side height, the steel ring ground clearance can be below 5 centimetres, 0.5 more than centimetre, so tire radius can not shorten much quickly, because having propped up, steel ring loses the cover tire that charges support.Even tire radius shortens a bit, some deflection occurs in car, but is unlikely uncontrollable, and wheeled still.The 3rd, save elastomeric material, convenient processing, save cost.The steel ring ground clearance also can more than 5 centimetres, be decided according to needing.

3, explosion-protection equipment of tyre.It is the safety apparatus after the tire blast.Also can establish the tyre explosion proof function effect that inner support replaces steel ring in tire.Inner support refers to be positioned at tire, works the device of the protective action of blowing out.Inner support can be various shapes, as circular, banded, is positioned at tire, plays a supporting role.When blowing out, inner support is taken over weighting material and is supported whole loads.Such as two T shape semi-discs are arranged in cover tire, its vertical edge is stuck on steel ring, and horizontal edge is near cover tire, and when blowing out, T shape inner support has been propped up cover tire.Also can clamping plate be installed in the tire both sides, replace the tyre explosion proof function effect of steel ring.Clamping plate are fixed in tire one or both sides, clamping or encase the over half of cover tire side height, and ground clearance can be below 5 centimetres, more than 0.5 centimetre.Work the protective action of blowing out.Clamping plate also can be round frame shape, mesh is tabular.Clamping plate also can be positioned on known tire and play same purpose.Unpowered vehicle can be without this structure.

Conclude 2,3, it is characterized in that cavity is arranged on steel ring, the degree of depth of cavity surpasses the carcass line of centers of the inner tube of a tyre, and its degree of depth is enough to encase half of inner tube of a tyre volume.Or the bowl volume of steel ring surpasses the tire total volume half; Or have at least one side steel ring to encase the over half of cover tire side height; Or have on tire and encase the above plate object of cover tire side mid-height; It is explosion-proof that this structure also is applicable to known tyre.Or the cavity volume of cover tire is less than the tire total volume half; Or cover tire is not with cavity, namely there is no volume; As tabular cover tire, concave cover tire.Or the periphery of steel ring from the periphery of cover tire below 5 centimetres, more than 0.5 centimetre, namely the diameter of steel ring is less 1 to 10 centimetre than the diameter of cover tire.Showing when being located in, i.e. steel ring ground clearance can be below 5 centimetres, more than 0.5 centimetre.Liftoff very near.Or inner support arranged in tyre cavity; Or inner support connects with cover tire or/and steel ring.Inner support can be stile shape, T shape, bag-shaped, spherical, column, ring-type, but radial loop in tire, or axial array is in tire, or irregular layout.One or more inner supports can be arranged.Some inner supports can replace the interior charges of tire to play the carrying effect, as bag-shaped, the spherical inner support of inflation.Also can jointly play the carrying effect with the tire inner stuffing.Inner support can be actively coupled with steel ring, near the cover tire bottom surface, can be divided into two parts or many parts, can be divided into a plurality of bag-shaped, spherical, columns or multi-turn ring-type.Inner support can be made alone or in combination by materials such as metal, plastics, foam, rubber.Clamping plate can replace steel ring to form cavity.

4, plastics tyre.It is characterized in that the inner tube of a tyre makes with plastic film, plastic film can be that thickness is at the plastic sheeting below 1 millimeter.The plastics of available soft plastic, good springiness.Its job operation can be formed by connecting with plastic sheeting.Available one or an above slice plastic film are formed by connecting.Also available plastic film tape spiral is formed by connecting.Can first make very long plastic film pipe racks, get length mark on pipe racks, then block connecting into the inner tube of a tyre.Method of attachment can stick with glue, heat seal etc.Plastic film can be combined in the rubbery cover tyre inwall.Cover tire is made of plastic, or makes with plastics, building rubber compound; Or make with composite material.Or the plastics cover tire is with rubber surface.Bonding or the flush fit of rubber surface and plastics cover tire satisfies the needs of tire function.For increasing the earth-grasping force on cover tire surface, can select suitable synthetic plastics or composite material.Can be concavo-convex with connecting between plastics cover tire and top layer, connect concavo-convex gear-like, zig-zag, the corrugated of being.The steel ring of tire also available highstrenghtpiston is made.Or plastics are combined with metal and are made.Plastics have better sealing property than rubber, and have certain elasticity.Replace rubber to make tire with plastics, the characteristics such as have good seal performance, lightweight, rust protection, specious, cost is low.The normal pressure volume of the inner tube of a tyre can be greater than the volume of tire; Be that the normal pressure skin area of the inner tube of a tyre is greater than the skin area of tyre cavity.Normal pressure refers to equate with bar pressure.Be that the tire external and internal pressure equates.Inflation or when filling other weighting materials, the inner tube of a tyre is not subject to tension force is inflated at first formed tension force accepted and be limited in the volume of cover tire by cover tire within.The inner tube of a tyre is not owing to bearing tension force, or it is very little to bear tension force, and the one, can not burst, the 2nd, can not reduce sealing property because being subjected to the tension force effect.The plastics inner tube of a tyre, rubber inner tube be structure like this all.Owing to can not leaking, so tire can not wanted valve, primary filling, or filling in advance use throughout one's life.The plastics cover tire can resemble to cover tire and wear footwear with rubber surface, and is conveniently replaced.Cover tire and top layer useful binders bond together.Also movable connection tightens up by the tension force after filling.Plastic film can be attached to the rubbery cover tyre inwall, replace the inner tube of a tyre.Can be with the engaging structure of various shapes between cover tire and top layer, be conducive between the two fastening.The present invention makes Tire ﹠ Tube with transparent material, to increase aesthetic feeling, the convenient detection.As the plastic, transparent Tire ﹠ Tube.

5, flat cover tire.It is characterized in that the cover tire intracavity section is square or the axial straight or inwardly protruding in the bottom surface of inner chamber; Or the cover tire outside face is axially straight or recessed inwards; The inner tube of a tyre has and the corresponding outer shape of cover tire inner chamber.The normal pressure volume of the inner tube of a tyre can be greater than the volume of tire; Or the cover tire periphery under pressure state is axial flat.The circumference of the tire during the tire of said structure is conducive to keep moving does not change diameter, and namely tire the radius that is located in and do not shortened, and improves efficiency.The bottom surface of square cavities or inner chamber is straight structure axially, cover tire be located in to obtain well strong tire internal pressure support, makes it to keep radius constant.Known circular cover tire and the inner tube of a tyre make the cover tire periphery of pressurized be the axial circular arcuation, are unfavorable for keeping the diameter of tire constant.Flat cover tire also can be tabular, and namely the circumference circle of cover tire is inside and outside parallel tabular, there is no dual side-edge.

6, establish the tension band between Tire ﹠ Tube.The tension force of known tyre is almost born by cover tire entirely, so cover tire must have higher resistance to tension.Such one is that cost is high, the 2nd, affect the various performances of tire.Be difficult to improve as resistance to tension, cause the tire volume to increase.The present invention is provided with the tension band between Tire ﹠ Tube, partly or entirely bear the tension force that load or tire inner stuffing produce.The suffered tension force of cover tire is reduced greatly.This is the service life that is conducive to improve cover tire.The 2nd, the load capacity of enhancing tire.The 3rd, reduce the cost of changing cover tire.The available plastics of tension band, rubber, metal or synthetic material are separately or in conjunction with making.Can be made into that gummed is banded, metal gauze is banded, knit the tape shape.Available multiple material is in conjunction with making.Can be circular, flat ribbon.The tension band can be with soft top layer.Rubbery cover tyre can be bonded on the tension band, takes off after damaging to renew.
