Abstract
The utility model discloses a truck tyre tread which comprises a tyre crown part tread (A) and tyre shoulder part treads (B) positioned at two sides of the tyre crown part tread (A); and each of the tyre crown part tread (A) and the tyre shoulder part treads (B) consists of an upper layer tread (1) made of heat-resisting rubber and a lower layer tread (2) made of abrasion-resistant rubber, wherein the thickness h of the lower layer treads (2) of the tyre shoulder part treads (B) is 0.3-0.35 time of the thickness H of the upper layer tread (1); and the thickness of the lower layer treads (2) of the tyre shoulder part treads (B) is 3mm-4mm. The truck tyre tread provided by the utility model is simple in structure, solves the problem that the existing tyre tread can not achieve the coexistence of performances including abrasion resistance, stab resistance, tearing resistance, hot resistance, low heat generation and the like, meanwhile improves the anti-fatigue and themogenesis resistant performances of the tyre shoulder parts, and effectively solves the hollow shoulder problem during using process of tyres.
Description
Technical field
The utility model relates to a kind of tyre surface of tire, particularly a kind of heavy-duty truck tyre tread.
Background technology
tire protector is comprised of crown part tyre surface and the tire shoulder section tyre surface that is positioned at crown part tyre surface both sides, tire protector is the embodiment position of overall performance of tire most critical, require tread mix to have wear-resisting, anti-thorn, anti tear, heat-resisting, the performances such as low-heat-generation, due to polymer composite wear-resisting, anti-puncture, give birth to heat low, conflicting mutually between the performance such as heat-resisting, promote performance in a certain respect, must cause the decline of performance on the other hand, the making material that is to say simple change tire protector is difficult to reach that to make tyre surface have simultaneously wear-resisting, anti-thorn, anti tear, heat-resisting, the performance of low-heat-generation.
The utility model content
In order to solve the problems of the technologies described above, the utility model provides a kind of both wear-resisting, anti-thorn, heat-resisting heavy-duty truck tyre tread again.
to achieve these goals, the technical solution of the utility model is as follows: a kind of heavy-duty truck tyre tread, comprise crown part tyre surface (A) and be positioned at tire shoulder section's tyre surface (B) of crown part tyre surface (A) both sides, it is characterized in that: the upper strata tyre surface (1) that described crown part tyre surface (A) and tire shoulder section's tyre surface (B) are made by heat enduring rubber and being formed by lower floor's tyre surface (2) that antifriction rubber is made, wherein the thickness (h) of lower floor's tyre surface (2) of tire shoulder section's tyre surface (B) be upper strata tyre surface (1) thickness (H) 0.3-0.35 doubly, the thickness of lower floor's tyre surface (2) of described crown part tyre surface (A) is 3mm-4mm.
Adopt technique scheme, tyre surface is by the upper strata tyre surface and lower floor's tyre surface is two-layer forms, lower floor's tyre surface adopts antifriction rubber to make, pay attention to the performances such as tire wear, intensity, the upper strata tyre surface is made by heat enduring rubber, pay attention to the viviparous performance such as hot, heat-resisting of wheel, solved existing tire protector and be difficult to realize the performance such as wear-resisting, anti-thorn, anti tear, heat-resisting, low-heat-generation and the problem of depositing.Simultaneously, we the thickness of lower floor's tyre surface of tire shoulder section tyre surface is decided to be the upper strata tyre surface thickness 0.3-0.35 doubly, and the thickness of lower floor's tyre surface of crown part tyre surface is 3mm-4mm, the thickness of tire shoulder subordinate layer tyre surface increases, improve tire shoulder antifatigue, anti-thermogenesis performance, effectively solve the generation of the empty problem of shoulder in tire used.
As preferably: the thickness (h) of lower floor's tyre surface (2) of described tire shoulder section's tyre surface (B) is the thickness (H) 1/3rd of upper strata tyre surface (1).
Beneficial effect: the utility model is simple in structure, has solved existing tire protector and has been difficult to realize the performances such as wear-resisting, anti-thorn, anti tear, heat-resisting, low-heat-generation and the problem of depositing; Simultaneously, improve tire shoulder antifatigue, anti-thermogenesis performance, effectively solve the generation of the empty problem of shoulder in tire used.
