Description

Technical Field

[0001] This utility model relates to the field of tire design technology, specifically a belt layer composite component for improving tire shoulder clearance. Background Technology

[0002] The belt layer is a key component of the tire structure that comes into direct contact with the tread. When the tire has been used for a long time, the hardness of the tread base rubber decreases, which reduces the tire's shear resistance and makes it easy for the belt layer to delaminate from the tread. Delamination reduces the tire's durability and lifespan, requiring innovative designs to improve the hardness and shear resistance of the tread base rubber.

[0003] Based on this, a belt layer composite that improves tire shoulder clearance is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0004] The purpose of this invention is to provide a belt layer composite that improves tire shoulder clearance, thereby solving the problems in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A belt layer composite for improving tire shoulder clearance includes an airtight layer located at the innermost layer of the tire, the airtight layer being wrapped around the tire carcass, and the upper end of the tire carcass having a reinforcing mechanism for enhancing the rigidity and stability of the tire.

[0006] Based on the above technical solutions, this utility model also provides the following optional technical solutions: In one alternative: the reinforcement mechanism includes a belt layer, a shoulder pad rubber is provided on the outer side of the belt layer, a tire crown is provided on the outer side of the belt layer, the tire crown is attached to the tire sidewall, and an improvement structure for improving tire shoulder clearance is overlapped on the shoulder pad rubber.

[0007] In one alternative: the improved structure includes a shoulder pad type adhesive, with a shoulder pad type adhesive overlapping the shoulder pad adhesive.

[0008] In one alternative: the ends of the shoulder pad tape bundle are covered with a film.

[0009] In one alternative: the film is made of ethylene propylene rubber.

[0010] In one alternative: the adhesive is made of styrene-butadiene rubber, and a support pad is provided at the bonding position between the adhesive and the tire sidewall.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention innovates and modifies the tire shoulder component by adding a layer of rubber or a sheet to the existing belt layer, effectively reducing the probability of shoulder delamination. Compared with existing technologies, this design improves the traditional belt layer composite design by adding a layer of rubber or a sheet to the belt layer edge. The rubber material uses the same formula as the belt layer edge-wrapping sheet, and its thickness, width, and position can be adjusted as needed to suit tires of different sizes. This design reduces shear deformation between the belt layer endpoint and the tread compared to traditional designs, thus reducing shoulder gaps. Attached Figure Description

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0018] In one embodiment, such as Figures 1-4 As shown, a belt layer composite for improving tire shoulder clearance includes an airtight layer 1, which is located in the innermost layer of the tire. The airtight layer 1 is wrapped around the tire carcass 2. The upper end of the tire carcass 2 is provided with a reinforcing mechanism for enhancing the rigidity and stability of the tire. The airtight layer 1 and the tire carcass 2 provide a sealing layer, thereby enhancing the tire's service life and elasticity. like Figures 1-4 As shown, the reinforcing mechanism includes a belt layer 3, a shoulder pad rubber 4 on the outer side of the belt layer 3, a tire crown 5 on the outer side of the belt layer 3, the tire crown 5 adhering to the tire sidewall 6, and an improvement structure for improving tire shoulder clearance overlapping on the shoulder pad rubber 4. The belt layer 3 enhances the rigidity and stability of the tire, and together with the tire crown 5, they form the tire's support structure. like Figures 1-4As shown, the improved structure includes a shoulder pad rubber type 7, which overlaps the shoulder pad rubber 4. By adding a shoulder pad rubber type 7, the traditional belt layer composite design is improved into a belt layer edge overlap type rubber or film composite design, which can effectively reduce the probability of shoulder delamination. like Figures 1-4 As shown, the end point of the belt layer of the tire shoulder pad rubber 4 is covered with a rubber sheet 8. The rubber sheet 8 reduces the shear deformation between the end point of the belt layer and the tread, reduces the shoulder gap problem, and effectively reduces the probability of shoulder delamination. It adopts the same formula as the belt layer edge wrapping rubber sheet, and the thickness and width can be adjusted as needed to facilitate the use of tires of different sizes. like Figures 1-4 As shown, the rubber type 7 is made of styrene-butadiene rubber, and a support pad is provided at the bonding position between the rubber type 7 and the tire sidewall 6 to enhance the overall structural stability of the tire and improve the tire's load-bearing capacity and driving safety. The above embodiments disclose a belt layer composite component for improving tire shoulder gap. The traditional belt layer composite component design is improved by adding a shoulder pad rubber type 7, transforming it into a belt layer edge overlap type rubber or sheet composite component design. This effectively reduces the probability of shoulder delamination. The sheet 8 reduces shear deformation between the belt layer endpoints and the tire tread, mitigating shoulder gap and further reducing the probability of shoulder delamination. The rubber material used in the sheet 8 is formulated with the same material as the belt layer edge-wrapping sheet, and its thickness, width, and bonding position can be adjusted as needed, facilitating the use of tires of different sizes.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
