Abstract
The utility model discloses a composite tire surface made of polyurethane rubber, which comprises a rubber body and a pattern slot; a groove is formed on the rubber body; a polyurethane elastic body is arranged inside the groove. A part of area on the friction surface on the crown of the tire surface is made of polyurethane material; the other part consists of rubber material. The two parts of materials are integrated into one body through common crosslink. The polyurethane part improves the anti-friction performance of the tire surface; the rubber part guarantees the skid-proof property and braking performance of the tire surface; therefore, the comprehensive performances are superior to those of tire surfaces made of only rubber material or polyurethane material. The utility model can fulfill tire production with such technologies as composite extrusion or casting mode before sulphation with rubber tire body etc.; the process is substantially consistent with traditional arts of rubber tire production. When utilized in prior tire manufacturers or tire-renewing enterprises, the utility model has the advantages of saving investment and quick effect. Therefore, the utility model adapts to tire production for vehicles, tractors and tricycles etc.; the tire surface is adaptive to both low-speed tires and high-speed tires, and meanwhile, makes for tire renewing; in one word, the adaptive scope is rather broad.
Description
Technical field
The utility model relates to a kind of tread of tyre.
Background technology
Known tire protector is an elastomeric material, the wearing no resistance of rubber tread, and service life is short.Chinese patent 01114798 and 200310111979 disclosed tire protectors are the full-polyurethane elastomeric material, though the polyurethane tread resistance to abrasion is better than rubber tread, but braking ability and skid resistance are than rubber tread difference, and driving safety is poor, are mainly used in the low speed tire at present.
Summary of the invention
The purpose of this utility model is that a kind of poly-urethane rubber combined tire tyre surface will be provided, and this tyre surface not only resistance to abrasion is good, and braking ability and skid resistance.
The purpose of this utility model is achieved in that this tyre surface comprises rubber bodies, and tyre surface is provided with groove, is provided with groove above the rubber bodies, and polyurethane elastomer is positioned at groove.
The elastic polyurethane bulk area accounts for the 10-60% of tread cap wearing surface area, and the elastic polyurethane body thickness is greater than the degree of depth of groove.
The utility model is formed by areal array by rubber bodies and polyurethane elastomer, and promptly tread cap wearing surface part area is a polyurethane material, and another part is an elastomeric material.Two sections of material is combined into one by co-crosslinking (co-vulcanization).Polyurethane has partly improved the resistance to abrasion of tire protector, and rubber part has guaranteed the skid resistance and the braking ability of tyre surface, and Combination property is better than mono-elastomeric material tyre surface and polyurethane material tyre surface.Can make tire with technologies such as rubber tyre body co-vulcanization again by compound (injection) mode of extruding or pour into a mould, basic identical with traditional rubber tire production technology.In present tire enterprise, when the enterprise that rebuilds a tyre uses, reduced investment, instant effect.Can be used for the production of tires such as automobile, trac., three-wheel vehicle.Both can be used for the low speed tire, also can be used for high-speed tire, and also can be used for rebuilding a tyre, widely applicable.

The specific embodiment
In Fig. 1 and Fig. 2, this tyre surface is the longitudinal type decorative pattern, comprises rubber bodies 1, and tyre surface is provided with groove 3, and the tread cap gross area deducts the area that the groove area is crown wearing surface 4, is provided with groove above the rubber bodies 1, and polyurethane elastomer 2 is positioned at groove.
The area of the polyurethane elastomer 2 of tread cap account for crown wearing surface 4 area 10%.
In Fig. 3 and Fig. 4, this tyre surface is the mixed type decorative pattern, comprises rubber bodies 1, and tyre surface is provided with groove 3, and the tread cap gross area deducts the area that the groove area is crown wearing surface 4, is provided with groove above the rubber bodies 1, and polyurethane elastomer 2 is positioned at groove.
The area of the polyurethane elastomer 2 of tread cap account for crown wearing surface 4 area 30%.
In Fig. 5 and Fig. 6, this tyre surface is the lateral type decorative pattern, comprises rubber bodies 1, and tyre surface is provided with groove 3, and the tread cap gross area deducts the area that the groove area is crown wearing surface 4, is provided with groove above the rubber bodies 1, and polyurethane elastomer 2 is positioned at groove.
The area of the polyurethane elastomer 2 of tread cap account for crown wearing surface 4 area 60%.
Claims (2)
