High piercing-resistance, cutting-resistant semi-steel engineering tyre and manufacturing method thereof

Abstract

The invention discloses a high pierce-resistant, cutting-resistant semi-steel engineering tire and a preparation method thereof. The engineering tire comprises a tire body consisting of a plurality layers of high intensity fiber cord fabric, wherein the outside of the tire body is fixedly adhered with a tire thread made of tire thread rubber; the tire thread comprises a tire crown face and a tire side face; and a steel wire buffer layer is arranged between the tire crown face and the tire side face, and comprises two to ten layers of steel wire cord fabric. As the tire body adopts the plurality layers of high intensity fiber cord fabric, the engineering tire has high bearing capacity and high efficiency. As the buffer layer adopts the steel wire cord fabric, the tire crown has high rigidity and strong pierce-resistant performance; the tire body has little circumferential deformation during the driving of a vehicle; and the vehicle drives stably, has little rolling resistance, strong performance of passing rigid rocky mining areas and saves fuel.

Description

technical field [0001] The invention relates to a structural design of an engineering tire, in particular to a high-puncture-resistant and cut-resistant semi-steel engineering tire, and further relates to a preparation method. Background technique [0002] At present, the use environment of engineering tires is generally on construction machinery such as bulldozers and loaders operating in rocky environments such as mining areas, quarries and construction sites, such as figure 1 As shown, the main components of engineering tires are tread 6, buffer layer (or belt layer) 5, carcass 1, sidewall 4, and several parts of bead. At present, engineering tires generally adopt bias tires or For radial tires and bias-ply engineering tires with ordinary structures, the buffer layer is generally made of high-strength fiber nylon 66 or nylon 6, the specification is generally 930dext / 2, and the breaking strength of a single cord is at least 107.8N. Due to the harsh use conditions, the fibe...

[0002] At present, the use environment of engineering tires is generally on construction machinery such as bulldozers and loaders operating in rocky environments such as mining areas, quarries and construction sites, such as figure 1 As shown, the main components of engineering tires are tread 6, buffer layer (or belt layer) 5, carcass 1, sidewall 4, and several parts of bead. At present, engineering tires generally adopt bias tires or For radial tires and bias-ply engineering tires with ordinary structures, the buffer layer is generally made of high-strength fiber nylon 66 or nylon 6, the specification is generally 930dext / 2, and the breaking strength of a single cord is at least 107.8N. Due to the harsh use conditions, the fiber cord is easy to punctured, causing the crown of the tire to be punctured, punctured, cut off and other early damages; Easy to rust and break, causing tire burst
