Description

Technical Field

[0001] This utility model relates to the field of semi-steel radial tire technology, specifically a high-durability semi-steel radial tire. Background Technology

[0002] Semi-steel radial tires are a type of radial tire. Their carcass cords are arranged in the radial direction, and the buffer layer is composed of steel cords arranged circumferentially or nearly circumferentially. They consist of six parts: tread, carcass, sidewall, buffer layer (belt layer), bead, and inner liner. According to materials, they can be divided into all-steel radial tires, semi-steel radial tires, and all-fiber radial tires. Among them, the carcass of semi-steel radial tires is made of nylon or polyester fiber, and the belt layer is made of steel cord fabric. They have both wear resistance and low fuel consumption characteristics. Compared with bias tires, their rolling resistance is reduced by 15%-20%, their load-bearing capacity is increased by more than 10%, and their service life is extended by 30%.

[0003] Existing semi-steel radial tires typically have grooves in the tread to achieve lateral anti-skid and heat dissipation effects. However, the grooves often suffer from chipping and cracking due to insufficient sidewall support, which affects their service life. Therefore, a semi-steel radial tire with high durability is needed. Utility Model Content

[0004] The purpose of this invention is to provide a high-durability semi-steel radial tire, which solves the problems mentioned in the background art.

[0005] This application provides a high-durability semi-steel radial tire, including a tire body. A groove is formed circumferentially at the middle position of the tread of the tire body. The inner walls of both sides of the groove are symmetrically and integrally vulcanized with annular reinforcing strips extending along the length of the groove. The outer walls of the two annular reinforcing strips on opposite sides are provided with inclined surfaces. The inclined surfaces gradually slope outward from the bottom side of the groove towards the opening side. The interior of the groove is integrally vulcanized with reinforcing ribs along the width direction. The two ends of the reinforcing ribs are integrally vulcanized and fixed to the outer walls of the two annular reinforcing strips respectively.

[0006] In use, the ring-shaped reinforcing strips strengthen the support of the groove sidewalls, and the symmetrical bevels on both sides form a funnel-shaped opening, which reduces the resistance to water flow. The reinforcing ribs further stabilize the ring-shaped reinforcing strips on both sides to improve the overall structural strength. This effectively prevents the grooves from chipping and cracking due to insufficient support, and ensures unobstructed drainage channels, significantly improving the durability and safety of the tire body. The ply and belt layers increase the rigidity of the tire body tread and ensure even stress distribution on the tread. The anti-slip protrusions improve the tire body's anti-slip properties and wear resistance.

[0007] Optionally, the outer wall of the tire body is fixedly connected with two sets of anti-slip protrusions, and the two sets of anti-slip protrusions are located on both sides of the groove.

[0008] By adopting the above technical solutions, anti-slip protrusions can improve the anti-slip properties and wear resistance of the tire body.

[0009] Optionally, both ends of the reinforcing rib extending along the length of the groove are chamfered.

[0010] By adopting the above technical solution, the chamfer can eliminate the sharp edges at both ends of the reinforcing rib, reduce the resistance to water flow, and allow water to drain more smoothly from the trench.

[0011] Optionally, a ply layer and a belt layer are provided between the tire body and the tread, with the belt layer located on the side of the ply layer closest to the tread.

[0012] By adopting the above technical solutions, the rigidity of the tire body tread can be increased, while ensuring uniform stress on the tread.

[0013] Optionally, the tire body has integrally vulcanized sidewalls on both sides, and the sidewalls smoothly transition to the tread of the tire body.

[0014] By adopting the above technical solutions, stress concentration at the junction of the tire sidewall and the tire tread can be reduced.

[0015] Optionally, the top of the annular reinforcing strip is located at the midpoint inside the groove.

[0016] By adopting the above technical solution, the annular reinforcing strip is prevented from protruding from the tire tread and from being worn.

[0017] Optionally, the inclined surface forms an angle of 18°-20° with the inner wall of the groove.

[0018] By adopting the above technical solution, the two annular reinforcing strips form a trumpet-shaped opening, which not only strengthens the inner wall of the trench bottom, but also does not obstruct the water flow.

[0019] Optionally, the annular reinforcing strip is made of rubber.

[0020] By adopting the above technical solution, the tire body can adaptively adjust to the deformation of the tire body during driving, avoiding the breakage of the annular reinforcing strip and groove due to excessive rigidity.

[0021] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:

[0022] The technical solution of this application strengthens the sidewall support of the groove by using annular reinforcing strips, and forms a funnel-shaped opening with the slope to reduce the resistance of water flow. The annular reinforcing strips on both sides are then firmly connected with reinforcing ribs to improve the overall structural strength. This effectively prevents the groove from chipping and cracking due to insufficient support, and ensures that the drainage channel is unobstructed, significantly improving the durability and safety of the tire body.

[0029] Please see Figure 1-4 This utility model provides a technical solution: a high-durability semi-steel radial tire, including a tire body 3. A groove 1 is formed circumferentially at the middle position of the tread of the tire body 3. The inner walls of both sides of the groove 1 are symmetrically and integrally vulcanized with annular reinforcing strips 5 extending along the length direction of the groove 1. The top of the annular reinforcing strips 5 is located at the half position inside the groove 1. To prevent the annular reinforcing strips 5 from protruding from the tread of the tire body 3 and to avoid wear on the annular reinforcing strips 5, the outer walls of the opposite sides of the two annular reinforcing strips 5 are provided with inclined surfaces 8. The inclined surfaces 8 gradually slope outward from the bottom side of the groove 1 towards the opening side. The interior of the groove 1 is integrally vulcanized with reinforcing ribs 6 along the width direction. The two ends of the reinforcing ribs 6 are integrally vulcanized and fixed to the outer walls of the two annular reinforcing strips 5 respectively. The two ends of the reinforcing ribs 6 extending along the length direction of the groove 1 are provided with chamfers 7. The chamfers 7 can eliminate the sharp edges at both ends of the reinforcing ribs 6, reduce the resistance to water flow, and allow water to drain more smoothly from the groove 1.

[0030] In the technical solution of this utility model, two sets of anti-slip protrusions 2 are fixedly connected to the outer wall of the tire body 3, and the two sets of anti-slip protrusions 2 are located on both sides of the groove 1 respectively; the anti-slip protrusions 2 can improve the anti-slip properties and wear resistance of the tire body 3.

[0031] In the technical solution of this utility model, a ply layer 9 and a belt layer 10 are provided between the tire body 3 and the tread, and the belt layer 10 is located on the side of the ply layer 9 close to the tread; this can increase the tread rigidity of the tire body 3 and ensure that the tread is subjected to uniform force.

[0032] In the technical solution of this utility model, the tire body 3 is provided with integrally vulcanized sidewalls 4 on both sides, and the sidewalls 4 and the tire body 3 have a smooth transition; this can reduce stress concentration at the junction of the sidewalls 4 and the tire tread.

[0033] In the technical solution of this utility model, the inclined surface 8 forms an angle of 18°-20° with the inner wall of the groove 1, so that the two annular reinforcing strips 5 form a trumpet-shaped opening, which not only strengthens the inner wall of the bottom of the groove 1, but also does not obstruct the water flow.

[0034] In the technical solution of this utility model, the annular reinforcing strip 5 is made of rubber; it can adaptively adjust with the deformation of the tire body 3 during driving, thus avoiding the annular reinforcing strip 5 and the groove 1 from breaking due to excessive rigidity.

[0035] In use, the annular reinforcing strip 5 strengthens the support of the sidewall of the groove 1, and the symmetrical inclined surfaces 8 on both sides form a funnel-shaped opening, which reduces the resistance to water flow. The reinforcing rib 6 firmly connects the annular reinforcing strips 5 on both sides to improve the overall structural strength. This effectively prevents the groove 1 from chipping and cracking due to insufficient support, and ensures that the drainage channel is unobstructed, significantly improving the durability and safety of the tire body 3. The ply layer 9 and belt layer 10 can increase the tread rigidity of the tire body 3, while ensuring uniform stress on the tread. The anti-slip protrusions 2 can improve the anti-slip properties and wear resistance of the tire body 3.
