Description

Automobile-used safely and efficiently wheel

This case is a division, original application day 2003.1.1, application number 03101364.3, title " safe and efficient tire ".

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

Two, background technology: not enough below known tire exists:

1, poor stability.Tire is in operation and can blows out, and especially front-wheel tyre-burst is accidents caused thus continuous, 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 the tire be under pressure with pressure constantly change with compressional movement process constantly 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 the tire, produces high pressure, causes blowing out.It is thus clear that gas conduction property is poor, being prone to give 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 being gone in the same time sharply reduces, and makes the vehicle; As automobile respectively to take turns range ability inconsistent; Thereby it is the hard-over campaign in the center of circle that car is taken place to blow out, and the driver has little time to handle, 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 is meant tire in use, the work capacity of accomplishing in the unit time.Also refer to useful work shared percentum in total work.Such as motor tire, under the identical situation of other conditions, the tire of sufficient gas is higher than the tire efficient of deficency.It is the distance that unit energy is gone.The reason that efficient is not high has many, and one of reason is that tire inner stuffing performance inconsistency is fitted.Known tire inner stuffing is an air.The molecular structure of air is very loose, is compressed, changes volume easily.And before being pressed into liquid, its volume always is in labile state.Like this, behind filling pressure air in the tire, because the mutability of volume of air makes the diameter of tire always be in unsteady state.Inflation pressure is excessive, fragile again inside and outside tire.Such as automobile, its tire the radius that is located in and can be shortened during load.In fact, most motor tire and is located in radius and when load, can shortens.And the radius of tire except that the below do not shorten, and be elongated to some extent owing to the increase of pressure on the contrary.Like this, the wheel in the motion always will overcome resistance and advance, or even improves constantly whole center of gravity and move.Because being positioned at wheel and is located in the fwd radius of wheel the radius that is located in than wheel long.So just produce a large amount of useless power consumption, reduced efficient.Again because the load power poor (for liquid, solid) of gas so tire must be made very greatly, could satisfy the carrying demand.This just causes material, worker's waste, and has increased weight, increases energy consumption.

3, tire material poor performance.The material of inside and outside tire is a rubber, and the air-tightness of rubber is not fine, and gas filed pressure is big more, and temperature is high more, and its air-tightness is poor more.The original very high tire of pressure has just become flat soon, and poor air-tightness is a 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 big resistance for the tire in the motion, the waste energy.The tyre rim of the steel ring of tire, especially automobile, trac. is processed with steel plate, has both increased the car deadweight, is prone to again get rusty, and 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, promptly be located in, keep radius constant.Such as automobile, need tire certain area that lands to be arranged carrying after the 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 the 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 big, has only inwards and contracts, and has so just become a plane, and tire the radius that is located in and therefore shortened, and produces aforesaid resistance of motion.It is thus clear that 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, have only when wheel be located in when being an axial line, tire motion 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 big more, and radius is shorter, waste energy more.

5, the rubbery cover tyre dual-side is too high.Cover tire has the three parts, the side and the dual-side that land.The cover tire dual-side is too high, has both wasted elastomeric material, and it is constant to be unfavorable for that again tire is keeping being located in radius.When tyre load, outer swollen distortion be prone to take place 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 the 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, because aforesaid background technology causes damaged tyres easily, 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 in tire, to inject the water of tire internal volume below 1/3, and purpose is to utilize water on the go generation inertia energy-conservation.Above-mentioned technology can not solve the deficiency that tire exists.Known tyre needs often inflation, and is to guarantee air pressure, therefore inconvenient.Again because complex structure is installed, dismantles, keeps in repair all inconvenient.

The deficiency of known technology also will combine particular content to further specify 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, changes 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 abundance.Or liquid is full of the space of wheel tyre cavity except that 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, cmpd.Or charges are the critical mass state between solid, liquid, the gas.Like semifluid.Or charges are that the aggregation of powdery, granular solids is or/and binder.Expanded material also is like foamed plastic, foamed rubber.Liquid can be water, or the compound of water and other materials or hydrate.The also compound or the cmpd of oil or oil and other materials.Therefore this tire can be apneustic full closeding state, solid state owing to be not easy to leak.Can insert when the fit a tyre like the paste charges, lean on the clamping plate extruding to form filling pressure to carry, this tire can be solid shape, also has the foam inner tube of a tyre also can be solid shape, and they all can not have valve.The solid filling thing can be the interior support that the present invention will address.Filling is promptly filled.Liquids and gases all are fluids, observe same fluid rule, and the damping of gas and carrying effect will realize that finally say from this meaning, liquid or gas can obtain same damping and carrying effect as the tire charges through the elasticity and the intensity of cover tire.The size of tire capacity is decided by ply rating and area of thrust surface, and under these two condition unmodified situation, the space is provided with the solid filling thing in tire, does not influence the tire effect, and can play the supporting role after blowing out.Supporting role also with after state.As the tire charges, many advantages are arranged with liquid or solid or its composite than gas filling thing.The one, the water tightness of rubber, plastics is better than air-tightness, the moisture subchain than gas strand combine more closely, more solid, fugacity not.So just reduced frequent gas filed trouble, 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 property is than gas difference, temperature just is difficult for raising, being difficult for expanding in the tire like this, can therefore not produce high pressure and burst tire and mis-use breakdown.The 3rd, even blow out, liquid, lotion, solid can not resemble to be rushed out the gas quickly entirely, causes flat tire, leads to a disaster.Still can exercise after blowing out, until reparation.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, cost-cutting.Liquid is different with the effect of liquid in the known tire in the tire of the present invention, and liquid effects is tire patching or plays effect of inertia in the known tire.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.Because the incompressibility of liquid, thus also atmospheric pressure state of liquid in the tire, but still can play the carrying effect.Normal pressure refers to equate with bar pressure that promptly the tire external and internal pressure equates.When the elastic reaction of cover tire during in liquid, the liquid in the tire has had pressure, becomes pressure fluid.Because liquid, lotion, colloid has with gas like or identical dimensional instability and the elasticity under the closed state, so can replace gas as the tire charges.And has the unexistent plurality of advantages of gas.Liquid is only below 1/3 or 1/3 in the known tire, and the present invention can have living space in being full of tire more than 1/3.At realm of nature, solid, liquid, gas do not have boundary completely, and therefore, charges of the present invention also can be the critical mass states of solid, liquid, gas.Flock together solid powder/particle, be closed in and make charges in the tire, also can play the effect of flowing material.Because of thinner solid powder/particle also has flowing power, can produce local deformation, recessed such as inwards, and transmit pressure.Under the osed top state, 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 the tire.Like 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.For waterproof at ice up in winter, can in water, add compound or hydrate that other materials form water.Use instead oil or oil compound or cmpd.This charges also can be used on non-season in winter or other places certainly.Charges are the compound or the cmpd of water, other materials beyond the oil also.In the charges (like liquid) various additives can be arranged, like leak preventer, maintaining agent, anti-freeze additive, anti fouling composition etc.The tire of different purposes can have the charges of different performance.Since be 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 make things convenient for use widely, raise the efficiency.

2, enclose shallow tire deeply.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 a volume seldom in steel ring, only account for below 1/3 of whole tire total volume.Steel ring does not encase the cover tire except that the rim of the mouth.Tire capacity is meant the inner space of tire, and promptly cover tire and steel ring combine space in the formed tire, is used for the filling material, supports the volume and the elasticity of supporting cover tire of cover tire.Known cover tire has the three parts, 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, because the round property that becomes of fluid, dual-side i.e. outside protrusion, make tire the radius that is located in shorten, form resistance of motion.The 2nd, when blowing out, cover tire loses upholder in the tire, 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 difficulty of processing again.

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.Have only a small amount of volume on the cover tire or do not have volume.Just in time be to reverse known technology.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 big on one side, little on one side.But second splint weld together, also available bolt or fixedly moulding of collar.During installation, can put cover tire earlier, with clamping plate cover tire clamped again, be fixed on the 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 take place after any material is stressed, just amount varies in size.In fact, also can be out of shape behind the tire force of the present invention, tire the radius that is located in and also can be shortened, and just for known technology, it is much little that the amount that shortens is wanted, thereby reach 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, and the steel ring ground clearance can be below 5 centimetres, more than 0.5 centimetre; So tire radius can not shorten much quickly,, steel ring loses the cover tire that charges support because having propped up.Even tire radius shortens a bit, some deflection takes place in car, but is unlikely uncontrollable, and drivable still.The 3rd, save elastomeric material, convenient processing, save cost.The steel ring ground clearance also can be decided according to needing more than 5 centimetres.

3, explosion-protection equipment of tyre.It is the safety apparatus after the tire blast.Support replaces the protective action of blowing out of steel ring in also can in tire, establishing.Interior support refers to be positioned at tire, works the device of the protective action of blowing out.Interior support can be different shape, as circular, banded, is positioned at tire, plays a supporting role.When blowing out, interior support is taken over weighting material and is supported whole loads.Such as two T shape semi-discs are arranged in the outer tyre, its vertical edge is stuck on the steel ring, and horizontal edge when blowing out, has propped up cover tire near cover tire in the T shape.Also can clamping plate be installed in the tire both sides, replace the protective action of blowing out of steel ring.Clamping plate are fixed in the 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 the 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 the 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 the half the of inner tube of a tyre volume.Or the bowl volume of steel ring surpasses the half the of tire total volume; Or have at least one side steel ring to encase the over half of cover tire side height; Or have on the tire and encase the above plate object of cover tire side mid-height; This structure is applicable to that also known tyre is explosion-proof.Or the cavity volume of cover tire is less than the half the of tire total volume; Or cover tire is not with cavity, promptly do not have volume; Like 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, promptly the diameter of steel ring is littler 1 to 10 centimetre than the diameter of cover tire.Showing when being located in that i.e. steel ring ground clearance can be below 5 centimetres, more than 0.5 centimetre.Liftoff very near.Or interior support arranged in the tyre cavity; Or interior support connects with cover tire or/and steel ring.Interior support can be stile shape, T shape, bag shape, spherical, column, ring-type, but radial loop in tire, or axial array is in tire, or irregular layout.One or more interior supports can be arranged.The interior support that has can replace the interior charges of tire to play the carrying effect, like gas filed bag shape, spherical interior support.Also can play the carrying effect jointly with the tire inner stuffing.Interior support can connect with steel ring is movable, near the cover tire bottom surface, can be divided into two parts or many parts, can be divided into a plurality of bags of shapes, spherical, column or many loops.Interior support can by materials such as metal, plastics, foam, rubber separately or combination process.Clamping plate can replace steel ring to form cavity.

4, plastics tyre.It is characterized in that the inner tube of a tyre processes 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 symphysis connect and form.Also available plastic film tape spiral is formed by connecting.Can process very long plastic film pipe racks earlier, on pipe racks, get length mark, block connecting into the inner tube of a tyre then.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 processes with plastics, building rubber compound; Or process with composite material.Or the plastics cover tire has the rubber top layer.Rubber top layer and the bonding or flush fit of plastics cover tire satisfy the needs of tire function.For increasing the earth-grasping force on cover tire surface, can select suitable synthetic plastics or composite material for use.Can have between plastics cover tire and the top layer and connect concavo-convexly, connect concavo-convex gear-like, zig-zag, the corrugated of being.The steel ring of tire also available highstrenghtpiston process.Or plastics and melts combine are processed.Plastics have better sealing property than rubber, and have certain elasticity.Replace the rubber manufacture of tires with plastics, have good seal performance, in light weight, rust protection, specious, characteristics such as cost is low.The normal pressure volume of the inner tube of a tyre can be greater than the volume of tire; Be the skin area of the normal pressure skin area of the inner tube of a tyre greater than 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 does not receive tension force is inflated formed tension force and is at first accepted and be limited within the volume of cover tire by cover tire.The inner tube of a tyre is not owing to bear 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 receiving the tension force effect.The plastics inner tube of a tyre, rubber inner tube be structure like this all.Owing to can not leak, so tire can not wanted valve, primary filling, or filling in advance use throughout one's life.The plastics cover tire can have the rubber top layer, resembles to cover tire and has worn footwear, and is conveniently replaced.Cover tire and top layer useful binders bond together.Also movable connection tightens up by the tension force after the filling.Can plastic film be attached to the rubbery cover tyre inwall, replace the inner tube of a tyre.The engaging structure that can have different shape between cover tire and the top layer helps between the two fastening.The present invention makes Tire & Tube with transparent material, to increase aesthetic feeling, the convenient detection.Like 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 external 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 the pressure state is axial flat.The circumference of the tire during the tire of said structure helps keeping moving does not change diameter, and promptly tire the radius that is located in and do not shortened the raising 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.The known circular cover tire and the inner tube of a tyre make the cover tire periphery of pressurized be axially circular-arc, are unfavorable for keeping the diameter of tire constant.Flat cover tire also can be tabular, and parallel tabular inside and outside promptly the circumference circle of cover tire is does not have dual side-edge.

6, establish the tension band between the 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, influence the various performances of tire.Be difficult to improve like 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 are produced.The suffered tension force of cover tire is reduced greatly.This is the service life that helps improving cover tire.The 2nd, strengthen the loading of tire ability.The 3rd, reduce the cost of changing cover tire.The available plastics of tension band, rubber, metal or synthetic material are separately or combine to process.Can be made into that gummed is banded, metal gauze is banded, knit the tape shape.Available multiple material combines to process.Can be circular, flat ribbon.The tension band can have soft top layer.Rubbery cover tyre can be bonded on the tension band, takes off after damaging to renew.
