Abstract

The utility model discloses a tire with novel zero degree area is restrainted layer, including side wall, child hat, zero degree area of restrainting the layer, the centre-to-centre spacing of two adjacent steel wires on zero degree area of restrainting the layer is greater than two times of steel wire diameter, and zero degree area of restrainting the layer and be parallel winding and be two-layer of staggered arrangement. Because the density of the single layer of the zero-degree belted layer is low, the zero-degree belted layer is wound for two circles in the tire, and the upper layer and the lower layer are arranged in a staggered mode, so that the effect of an actual belted layer is formed, and the abnormal abrasion of the zero-degree belted layer is effectively prevented.

Description

There is the tire of novel zero-degree belt

Technical field

The utility model relates to a kind of tire, relates in particular to a kind of for having novel zero-degree belt structure tire.

Background technology

Tire belt is the important component part of tire construction, except playing mitigation impact effect, also plays the effect of banding carcass, be the main stressed member of tire, and tire belt also has variety classes, and modal is zero-degree belt.As shown in Figure 1, tire 9 includes sidewall 91, crown 92, zero-degree belt 93 at present, and what current bracing ply the most often adopted is 3+0 ° of structure design, and the two-layer winding of zero degree structure, sees it is two-layer from tire section.Owing to being two-layer bracing ply, not only cost of idleness, and also to make bracing ply in tire construction be intermediate thin and both sides are thick, causes easily producing inordinate wear in driving process.

Utility model content

The technical problems to be solved in the utility model is to provide a kind of tire that has smooth zero-degree belt and prevent zero-degree belt inordinate wear.

The utility model is achieved by the following technical solution: the tire that the utlity model has novel zero-degree belt, comprise sidewall, crown, zero-degree belt, the width between centers of two adjacent wires of zero-degree belt is greater than two times of steel wire diameter, and zero-degree belt is wound in parallel and is the two-layer of staggered floor arrangement.

Preferably, zero-degree belt is shaped as wavy.

Preferably, agree with mutually on the surface of two-layer zero-degree belt, and thickness is less than two times of zero-degree belt steel wire diameter.

Compared with prior art, the density of the zero-degree belt individual layer of the utility model tire is lower, and in tire, zero-degree belt is wound around two circle and upper and lower two-layer employing Heterogeneous Permutations, forms actual one deck bracing ply effect.Because every steel cord has all been wound around two circles, also just solve the strength problem of joint area.Both play constraint, the banding effect of original zero-degree belt, can reduce again half cost, and zero motherwort bracing ply overall leveling, consistency of thickness, avoids the inordinate wear in tire driving process, promotes the wear hardness of tire.

Detailed description of the invention

Please refer to shown in Fig. 1, the zero-degree belt 13 that the utlity model has the tire 1 of novel bracing ply is to have low-density zero-degree belt 13, it is two times that distance between two adjacent wires 131 centers of zero-degree belt 13 is greater than steel wire 131 diameters, preferably, zero-degree belt 13 is waveform.Please refer to Fig. 3, shown in Fig. 4, the utility model tire 1 has the structure of conventional tire, comprise sidewall 11, crown 12, zero-degree belt 13, but in the utility model, zero-degree belt 13 is two-layer for staggered floor arrangement, be zero-degree belt 13 along tire circumferential direction on bracing ply (not label), under or between wound in parallel two enclose, and the steel wire 131 of ground floor zero-degree belt 13 is between the steel wire 131 of second layer zero-degree belt 13, the wavy surface of zero-degree belt 13 is agreed with mutually, thereby guarantee the thinner thickness of two-layer zero-degree belt 13, there is the effect of one deck zero-degree belt.

Described above is preferred embodiments of the present utility model; only that example effect does not limit protection domain of the present utility model, not departing from the distortion of spirit of the present utility model, amendment all falls in the protection domain that the utility model claim limits.
