tire belt structure

Abstract

The invention belongs to the technical field of tire structures, and in particular discloses a belted layer structure of a tire. A liner layer and a tire body are sequentially arranged inside the tire from inside to outside, and the outer grounded surface of the tire is a tire tread. The belted layer structure is arranged between the tire body and the tire tread, and comprises a first belted layer, a second belted layer, a first zero-degree belted layer and a second zero-degree belted layer, wherein the first belted layer is attached to the tire body; the second belted layer is attached to the upper end surface of the first belted layer; the width of the second belted layer is greater than that of the first belted layer; the first zero-degree belted layer and the second zero-degree belted layer are sequentially attached to the second belted layer and are in the same structure. By virtue of the belted layer structure, a good tire hooping effect can be achieved, the stress uniformity of a tire crown is effectively ensured, and irregular abrasion is prevented.

Description

technical field [0001] The invention belongs to the technical field of tire structures, in particular to a tire belt structure. Background technique [0002] Existing wheeled vehicles, especially large freight vehicles and mine vehicles, are driven on harsh road conditions, so in addition to ensuring the safety performance of the tires, it is also required that the crown of the tires can well control the amount of deformation , Let the tires be in the state of non-partial wear as much as possible, so that the tire life can be longer. These goals put forward higher requirements for the tires of trucks. The proposal of such a goal requires us to make corresponding changes to the structure of the tire belt. The tire belt is also called support layer, hard buffer layer or stabilizing layer. It is a material layer that tightens the carcass along the centerline of the tread. It has two functions: one is to ease the impact, and the other is to tighten the carcass, so it is the ma...

Problems solved by technology

[0003] At present, the tire belt structure in various tire companies generally adopts a four-layer belt structure or a composite structure of a three-layer belt structure and a zero-degree belt layer. Taking the four-layer belt structure as an example (such as figure 1 , figure 2 shown), the first belt layer 1 and the second belt layer 2 use high-strength cords arranged at a small angle in the same direction and are covered with high-hardness rubber, and the third belt layer and the fourth belt layer are also used The high-strength, small-angle cords arranged in the same direction are covered with high-hardness rubber. The result is that the small-angle belt layer will be partially overstretched in harsh road conditions, causing irregular wear of the tire and affecting the service life of the tire. and prone to tire blowout
