Description

Technical Field

[0001] This utility model belongs to the field of tire structure technology, and specifically discloses an all-steel radial tire with an S-shaped crown belt winding layer structure. Background Technology

[0002] All-steel radial tires have belt layers arranged at a certain angle. During heavy-duty driving, especially at high speeds under heavy loads, uneven angle arrangement can cause an increased angle effect, leading to decreased stability and tire blowouts. Furthermore, encountering rough road surfaces, such as uneven surfaces, stones, or other sharp objects that puncture the tire can damage the tread, even damaging the belt layers, increasing the risk of a blowout if not detected in time.

[0003] All-steel radial tires with crown-belt winding have more uniform ground stress and crown rigidity, providing greater clamping force during high-speed and sustained operation, tightening the tire carcass and belt layer, reducing tire deformation. The internal steel wires are continuously wound, making the tire have its own "seat belt", better dispersing the impact force when impacted. Even if the tire is punctured and deflated, the vehicle can still be controlled until it stops safely. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an all-steel radial tire with an S-shaped crown belt winding structure that can improve the radial expansion of the shoulder and crown after tire inflation, reduce the shear stress between the belt layers, and improve the safety and service life of the tire during driving.

[0030] In this utility model, the function of the filler film 3 is: on the one hand, to ensure the straightness of the crown wrapping layer body 4.3, so that the crown strip steel cord 4.1 in the crown wrapping layer body 4.3 stretches evenly after the tire is inflated; on the other hand, to increase the thickness of the rubber material between the crown wrapping layer body 4.3 and the second belt layer 2, thereby reducing the shear stress between the crown wrapping layer body 4.3 and the second belt layer 2.

After winding around 25 times, the crown band wrapping layer body 4.3 and the lower right layer 4.4 of the crown band wrapping layer are formed. Then, it is wound around the center of the fitting drum 6 times to form the upper right layer 4.5 of the crown band wrapping layer, thus forming an S-shaped crown band wrapping layer structure.

[0033] The all-steel radial tire with the above structure has more uniform ground stress and crown rigidity. During high-speed and sustained operation, the crown belt wrapping layer 4 provides greater clamping force, which tightens the tire carcass, the first belt layer 1 and the second belt layer 2, reducing tire deformation. The crown belt strip steel cords 4.1 inside the crown belt wrapping layer 4 are continuously wound, making the tire have its own "seat belt". When impacted, the impact force is better dispersed. Even if the tire is punctured and deflated, the vehicle can still be controlled until it stops safely.

[0034] Compared with existing all-steel radial tires without a crown belt, the advantages of using the crown belt winding layer 4 structure in this utility model are mainly as follows:

[0035] 1. Improve the overall rigidity of the tire crown, especially the rigidity of the tire shoulder, reduce the deformation of the left and right sides of the first belt layer 1 and the second belt layer 2, reduce heat generation, protect the first belt layer 1 and the second belt layer 2, and reduce fatigue damage to the first belt layer 1 and the second belt layer 2 caused by stress and strain.

[0036] 2. Ensure tire tread stability during high-speed driving and reduce uneven wear;

[0037] 3. Reduces rolling resistance, saving fuel and protecting the environment;

[0038] 4. Increased safety performance, improved tire puncture resistance, reduced the likelihood of crown bursts caused by external damage during driving, and significantly extended tire lifespan.

[0039] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although this utility model has been described in detail with reference to examples, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
