Problems solved by technology

[0002] With the development and progress of the country, the application of all-steel radial truck tires is increasing, which puts forward higher and newer requirements for the skeleton structure and load capacity of the tires. However, due to the single skeleton structure of all-steel radial truck tires, there is no With major technological innovations, the load-carrying capacity has not been greatly improved in essence, which makes the call for improving the load-carrying capacity more and more loud.

Embodiment Construction

[0013] The present invention will be further described below in conjunction with specific drawings.

[0014] Such as figure 1 As shown, the structure of the all-steel radial truck tire of the present invention includes a tread, a sidewall 4, a shoulder connecting the tread and the sidewall 4, a bead connected to the lower part of the sidewall 4, and a skeleton structure, and the skeleton structure consists of A layer of steel wire carcass cord 5, a layer of nylon wrapping layer 6 and an airtight layer 7 are formed, and the nylon wrapping layer 6 is filled between the innerliner 7 and the steel wire carcass cord 5; the bead includes a steel traveler 16, The steel ring complex composed of the upper apex 11 and the lower apex 14, the outer surface of the steel ring complex is turned up to the steel wire carcass cord 5 and the steel wire slit cloth 15, and the steel wire carcass cord 5 is turned up to the steel wire slit cloth 15. About 15mm away from the end point of the turn-up...

Abstract

The invention relates to an all-steel radial truck tire structure, comprising a tread, a sidewall, a tire shoulder connecting the tread and the sidewall, a bead connected to the lower part of the sidewall and a skeleton structure. The all-steel radial truck tire structure is characterized in that the skeleton structure comprises a layer of steel wire carcass ply, a layer of nylon wrap layer and aninner liner, wherein the nylon wrap layer is arranged between the inner liner and the steel wire carcass ply. The bead comprises a wheel rim composite, which is wrapped with a turnup steel wire carcass fabric and a steel wire chafer in sequence, wherein the steel wire carcass fabric is turned up to the outer end of the steel wire chafer turnup end to form a certain distance of gap. The inventionsolves the strength problem of the skeleton material on the sidewall part, the possibility of U-shaped blowout of the sidewall of a back wheel due to overload is reduced, and the bearing capacity of the tire is greatly improved.

Description

technical field [0001] The invention relates to an all-steel load-bearing radial tire structure, which belongs to the technical field of all-steel load-bearing radial tires. Background technique [0002] With the development and progress of the country, the application of all-steel radial truck tires is increasing, which puts forward higher and newer requirements for the skeleton structure and load capacity of the tires. However, due to the single skeleton structure of all-steel radial truck tires, there is no With major technological innovations, the load-carrying capacity has not been greatly improved in essence, which makes the call for improving the load-carrying capacity more and more loud. At the same time, overloading occurs frequently in our country, and there are many safety problems caused by U-shaped blasting on the sidewall of the tire after overloading every year. This makes it imperative to develop a tire with a structural load capacity that is better than that...
