Description

Technical Field

[0001] This utility model relates to the field of tire technology, and in particular to an outer protective structure for an all-steel radial tire. Background Technology

[0002] All-steel radial tires are high-performance tires widely used in commercial vehicles, such as trucks, buses, and construction machinery. Their structural design and material selection give them excellent load-bearing capacity, wear resistance, and durability.

[0003] Existing all-steel radial tires suffer punctures that damage the tread, leading to tire deflation. Therefore, we propose an outer protective structure for all-steel radial tires. Utility Model Content

[0004] The purpose of this invention is to provide an outer protective structure for all-steel radial tires to solve the aforementioned technical problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an outer protective structure for an all-steel radial tire, comprising a bead wire, a cord layer sleeved on the outside of the bead wire, an airtight layer bonded inside the cord layer, a steel wire layer bonded to the outer wall of the cord layer, a radial body provided at the connection between the steel wire layer and the cord layer, a belt layer bonded to the outer wall of the steel wire layer, a tire shoulder bonded to the outer wall of the belt layer, a tire crown bonded to the outer wall of the tire shoulder, a protective sleeve provided on the inner wall of the tire crown, tread blocks provided on the outer wall of the tire crown, and grooves provided at the connection between the tire crown and the tread blocks.

[0006] Preferably, the cross-sections of the cord layer, steel wire layer, and belt layer are all C-shaped. In this embodiment, by setting the cord layer, steel wire layer, and belt layer with C-shaped cross-sections, it is beneficial to improve the structural strength of the all-steel radial tire.

[0007] Preferably, the main body of the meridian is radially equidistantly distributed along the outer wall of the cord layer. In this embodiment, this facilitates the reduction of heat generation by the main body of the meridian and reduces the risk of tire blowout.

[0008] Preferably, the protective sleeve is mesh-like. In this embodiment, by setting a mesh-like protective sleeve, it is beneficial to improve the structural strength of the tire crown and prevent the tire crown from being punctured, which could lead to tire deflation.

[0009] Preferably, the grooves are distributed in an angular circumference along the central axis of the tire crown. In this embodiment, this improves the tire's grip, drainage performance, and wear resistance.

[0010] Preferably, two sets of tread blocks are provided, and the two sets of tread blocks are located on the outer edge of the tire crown. In this embodiment, by providing two sets of tread blocks, the protection of the tire crown is achieved.

[0011] Preferably, the groove is V-shaped. In this embodiment, by setting the V-shaped groove, the tire's grip performance is improved, and at the same time, accumulated water can be drained in time.

[0012] Beneficial effects: Compared with the prior art, this utility model is equipped with a mesh protective sleeve, which helps to improve the structural strength of the tire crown and prevent the tire crown from being punctured and causing the tire to deflate. By setting two sets of tread blocks, the tire crown is protected. By setting "V" shaped grooves, the tire's grip performance is improved. At the same time, water can be drained in time.
