Abstract

The utility model relates to a combined tyre, which belongs to a tyre in traffic and transportation. The existing tyre is integral, the whole tyre can be only discarded after patterns on the stepping surface of the tyre is abraded, and a large amount of waste is generated. The utility model sheath a tyre casing matched with the main body of the tyre in an embedded way on the main body of the tyre, and the outer surface of the tyre casing is provided with the patterns of the stepping surface. The combined tyre can be utilized continuously after abrasion when the tyre casing is replaced, the utility model has the advantages of material saving, low use cost, strong applicability and reliable operation, the patterns of the stepping surface can be made into various forms, and the tyre casing can be assembled, disassembled and replaced flexibly and conveniently.

Description

The compound type tire

Technical field

The utility model relates to the improvement of tire (cover tire), and especially the compound type tire belongs to the tire for vehicles in the communications and transportation.

Background technology

Existing tire for vehicles all is an one as motor tire, cycle casing etc., use was travelled after a period of time, and the decorative pattern on the tire tread at first is worn and flattens, though the other parts of tire are intact substantially, it is discarded whole tire also to have to, and causes very big waste.Simultaneously, the decorative pattern on the tire tread can not be changed, and can't adapt to the variation of multiple pavement conditions.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned deficiency, provide a kind of simple in structure, processing and manufacturing easily, change tire tread pattern compound type tire easily.

The technical scheme that realizes the utility model purpose is: this compound type tire, constitute by the tire main body, it is characterized in that on the tire main body, being set with the tire main body and inlay the tire overcoat that cooperates, the outside face of tire overcoat has tread pattern, on the contact surface of tire overcoat and tire main body, have the emboss pit of inlaying mutually, have limit coil on the inner periphery limit of tire overcoat.

This emboss pit of inlaying is mutually arranged along tire circumference mutual dislocation, the radial section shape of emboss pit can be circle, square, apart from shape etc., that emboss pit axial cross section shape can be is square, rectangle, trapezoidal etc., puts outside tire also the metallo-anti-skid stud can be housed.

Compare with existing one tire and the utlity model has following advantage: (1) tire overcoat of the present utility model selects for use the abrasion resistant quality matetrial to make, when needing changing of tire after the tread pattern wearing and tearing that put outside the tire, only can make tire continue to use behind the tire overcoat that need more renew, avoided waste before, will save material significantly after implementing to promote, reduce use cost; (2) tread pattern that puts outward of tire can be made into the different size form, as different floral designs, different gash depth, have the metal anti-skid stud or the like, use for selecting under different regions, Various Seasonal, the different road surfaces situation, comformability is strong; (3) the tire main body external diameter of this compound type tire is slightly larger than the tire outer casing internal diameter, when unaerated, can change the tire overcoat easily, the inflation back makes tire overcoat lock ring on the tire main body by tension force and structures such as limit coil, emboss pit, and dismounting is flexible, reliable operation behind the suit; (4) the utility model can be made into bike tire, motor tire etc., is widely used in the various vehicles such as civilian bicycle, automobile applied range.

Description of drawings

Accompanying drawing 1 is the cross-sectional view of a kind of embodiment combined bicycle of the utility model cover tire.Fig. 2 is the structural representation of another kind of embodiment combined vapor vehicle tyre.Fig. 3, the 4th, the radial section structural representation of emboss pit part.Fig. 5 is a kind of emboss pit cross-sectional view partly that has another embodiment of replaceable anti-skid stud of Fig. 1.Among the figure: 1 tire main body, 2 tire overcoats, 3 limit coils, 4 tongues, 5 grooves, 6 tread pattern, 7 anti-skid studs, 8 binding holes.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is further described.

With reference to Fig. 1,2, this compound type tire is made of tire main body 1, the tire overcoat 2 that is sleeved on the tire main body 1, has tread pattern 6 on the surface of tire overcoat, inner periphery limit at the tire overcoat has limit coil 3, and what have on the contact surface of tire main body and tire overcoat that dislocation arranges inlays tongue 4, the groove 5 that cooperates mutually.Radial section shape protruding, groove can be circle (with reference to Fig. 3), square (with reference to Fig. 4) etc., and for increasing the inlay resultant force between tongue and groove, the axial cross section of emboss pit is preferably made trapezoidal (with reference to Fig. 1,5).

With reference to Fig. 5, this embodiment has removable anti-skid stud in the emboss pit of combined bicycle cover tire, when tire overcoat tread pattern 6 skid resistances are not enough, detachable tire overcoat down, load onto anti-skid stud,, remove anti-skid stud when not required again to increase skid resistance.Remove behind the anti-skid stud binding hole 8 by caoutchouc elasticity and closure does not influence use.Also anti-skid stud can be buried underground and be fixed in the tire overcoat.

The utility model can adopt existing rubber tire technology and material, and processing and manufacturing is simply easy, and limit coil can be embedded in the tire overcoat with the osed top bead coil.

Claims

1, a kind of compound type tire, constitute by the tire main body, it is characterized in that on the tire main body, being set with the tire main body and inlay the tire overcoat that cooperates, the outside face of tire overcoat has tread pattern, on the contact surface of tire overcoat and tire main body, have the emboss pit of inlaying mutually, have limit coil on the inner periphery limit of tire overcoat.

2, according to the compound type tire of claim 1, it is characterized in that the said emboss pit of inlaying mutually arranges along tire circumference mutual dislocation, the radial section shape of emboss pit can be circle, square, apart from shape, emboss pit axial cross section shape can be square, rectangle, trapezoidal.

3,, it is characterized in that outside tire, putting also the metallo-anti-skid stud can be housed according to the compound type tire of claim 1.
