Abstract
The present invention has designed a kind of not gas filed tire, it is made up of the I-shape cover tire and the inner tube of a tyre in the groove that is contained in the I-shape cover tire, designed tire can be used with the steel ring of any wheel, because tire need not inflated, therefore not because of the charge air profit and loss, leak gas, blow out, the sense of discomfort that band etc. causes and the phenomenon that can't travel, therefore can reduce maintenance, increase the service life, save time, laborsaving.Design-calculated tire of the present invention can use no or little elastomeric material, and have travel steadily, little, the labour-saving performance of jolting, according to the pavement quality elasticity of scalable tire also.
Description
The invention belongs to the improvement of wheel tyre, especially relevant with airless tire.
Vehicle is one of main vehicle of people, usually form by steel ring and dress tire thereon, the most frequently used tire is an air-inflation tyre on the current market, most of bicycle, hand barrow, three-wheel vehicle all use this tire, the most normal defect that has of air-inflation tyre is, (1) gas leakage easily takes place and the influence use, need often inflate, bother, (2) are owing to be air-inflation tyre, as being punctured by sharp shaped material, or day thermal explosion tire, then need the tire patching inflation, even change tire and could use, (3) the thin wearing and tearing easily of wheel face, service life is short.In order to overcome airtyred above-mentioned shortcoming, multiple band tyre has appearred, be to improve the elasticity of band tyre, often be made into the airless tire of band cavity, also can be in cavity the various elastic bodys of filling.A kind of non-inflatable tyre that proposes among the CN86209438 is made up of the cover tire and the inner tube of a tyre, cover tire is around steel ring, the non metal elastic thing bigger by friction force constitutes, the inner tube of a tyre is the annular solid that is connected to each other formation by two ends, it can be plate spring, or coil spring, be fixed in the cover tire with fastener, the elasticity of this tire can be suitable with air-inflation tyre, but the tire of the plate spring shape inner tube of a tyre requires inner tube of a tyre material higher, otherwise bearing capacity is not enough, and tire is yielding, and use coil spring tire construction complexity, install, change trouble.A kind of band tyre is proposed in the U.S. Pat 4327793, this tire band cavity, do not inflate, can overcome airtyred some shortcoming, but its weak point also is tangible, 1. for to make tire that certain vibration damping and service life be arranged, must select for use and have good resistance to abrasion and elastomeric rubber simultaneously and make, even like this, its elasticity and vibration damping are still poor than gas filed slightly, 2. the both sides of tire in use are subjected to repeatedly the effect of shearing stress, are easy to generate endurance crack, and 3. the elasticity of tire is non-adjustable, skid resistance when snowfield travels is poor, 4. tire and contact area of ground are little, and less stable also is not suitable for travelling at mire, 5. strut member in the chamber and tire contact surface are little, the easy damaged tire.
The objective of the invention is to design a kind ofly do not inflate, use no or little elastomeric material, elasticity is adjustable, the tire of good stability.
Tire of the present invention is made up of the inner tube of a tyre (2) of I-shaped cross-section cover tire (1) and both sides band lugs (6), and the inner tube of a tyre (2) compression of band lug is installed between I-shape cover tire and the steel ring (4) in the formed space.
For make tire be adapted at winter freezing ground or the not high situation of pavement quality under use, can utilize the I-shape construction of cover tire to adjust the area of contact on tire and plane, improve elasticity, inlay (3) promptly is housed in the outer groove of I-shape cover tire.
Cover tire in the design-calculated tire of the present invention is the I-shaped cross-section structure, and its outer groove is contacted with ground by tread (5) towards the road surface, forms the space between inner groovy and steel ring and packs into and more than one depression is arranged on the lateral surface of the inner tube of a tyre, cover tire.The inner tube of a tyre is made up of the lug (6) and the body of both sides, and lug (6) extends upward the both sides that wrap in cover tire, and the inboard of lug has bossing to cooperate with depression on the cover tire, can block cover tire better.The height of lug is about half of cover tire height, outwards comes off to prevent cover tire to be subjected to axial force, and inner tube of a tyre body is extruded between cover tire and steel ring.The lowest positions of cover tire should be lower than the extreme higher position of the side of steel ring, to prevent to be subjected to axial force in the driving process Tire ﹠ Tube is outwards come off together.Inner tube of a tyre body can be with groove, to increase the elasticity of tire, has the effect of material-saving and expendable weight concurrently.Generally speaking, the width of cover tire is less than the width of steel ring (4) groove.Steel ring (4) can be any wheel-use steel material circle.
The wheel that assembles only has the tread (5) of cover tire to contact with ground under steam.For making wheel have cooresponding buffer capacity and cushioning performance, cover tire internal diameter and steel ring flute pitch are roughly 8 millimeters, and this spacing is the easy unstability of giant tyre too, generally are no more than 10 millimeters.Before the assembling, should make the inner tube of a tyre pack tightly steel ring less than the external diameter of steel ring groove with the internal diameter of the inner tube of a tyre of steel ring (4) mating part, unlikely getting loose, but too tightly can reduce the elasticity of the inner tube of a tyre again.From riding stability with do not damage the road surface and consider that the width of cover tire tread (5) is more suitable between the 4-5 millimeter.The outer groove height of I-shape cover tire should be considered the wearing and tearing of tread, is generally the 6-10 millimeter, has highly too greatly then not only taken material but also instability.Cover tire can select for use wear-resisting, harder rubber, engineering plastics or materials such as metallic material such as duralumin to make.The inner tube of a tyre then should be selected elasticity material preferably for use, as expanded cellular rubber, elastoplast etc.The cross section that is contained in the inlay (3) in the outer groove of I-shape cover tire can be roughly suitable with outer groove shapes, also can use the detouchable chain ring, its upper surface arc and exceed tread slightly when using the cooresponding inlay of cross section and outer groove shapes, can keep bigger contact surface when tire contacts with ground under pressure and improve elasticity, and can prevent to destroy ropy ground, inlay can select for use plastic rubber etc. that the elastic body manufacturing of moderate wear resistance is arranged.
Design-calculated tire of the present invention has following advantage:
[1] need not inflate, therefore not have gas leakage, blow out, prick problems such as tire, tire patching, easy to use,
[2] the tread height can be selected as required, obviously greater than airtyred thickness, and compression chord effect in service, so long service life, not fragile,
[3] owing to the inner tube of a tyre, cover tire role difference, can distinguish selection, cover tire is based on wear-resisting, therefore the inner tube of a tyre is using no or little under the situation of rubber to increase elasticity, vibration damping, and tire still has enough elasticity and vibration damping, even be better than air-inflation tyre, big with ground contact portion hardness, so driving dynamics is little, the I-shape tyre structure helps the improvement of stability.
[4] cover tire adopts I-shape construction just can adjust elasticity, the skid resistance of tire according to usage condition, the inlay of must not packing into when the road surface is better, and the bad inlay of packing in road surface uses.As when the freezing road traveling, the chain form inlay of can packing into improves skid resistance, reduces dangerous.
[5] design-calculated tire materials few, in light weight, can be used with the steel ring of any wheel.
Fig. 1 is the tire cross-section figure on the wheel steel ring of being contained in that proposes among the CN86209438.
Fig. 2 is the tire cross-section figure on the wheel steel ring of being contained in that proposes among the US4327793.
Fig. 3 is that design-calculated of the present invention is contained in the tire cross-section figure on the wheel steel ring.
