Abstract
Description
Technical Field
[0001] This utility model relates to the field of bicycle tubeless tire technology, and in particular to a racing puncture-proof road bicycle tubeless tire. Background Technology
[0002] Cycling is more than just a sport; it's a lifestyle. Road cycling is sweeping the globe at an astonishing pace, becoming a new favorite among urban elites, sports enthusiasts, and free explorers.
[0003] Ultra-thin tires offer significantly reduced resistance to obstacles such as sharp stones and road cracks, making them more susceptible to punctures. Simultaneously, extremely high tire pressure reduces the elastic buffer zone within the tire body. When cornering at high speeds, running over curbs, or experiencing severe impacts, stress becomes highly concentrated on the tire sidewall or the tire bead where it connects to the rim, greatly increasing the risk of sidewall tears or "snakebite" blowouts.
[0004] Therefore, puncture-resistant tubeless tires for racing road bikes are still needed to solve the above problems. Utility Model Content
[0005] This invention provides a puncture-proof tubeless tire for racing road bicycles that solves the above-mentioned problems.
[0006] The objective of this utility model is achieved through the following technical solution: A puncture-resistant road bicycle tubeless tire has the following components arranged sequentially in the thickness direction at the center of the tire: a tread layer, a reinforcing layer, a buffer layer, and an air-retaining layer. The reinforcing layer covers the buffer layer, and the buffer layer has a uniformly decreasing edge thickness as it extends toward both sides of the tire. The reinforcing roll layer is bent in the opposite direction at the edges near both sides of the tire, and then attached to the top of the buffer layer with the inner side facing outward; the reinforcing roll layer is a cotton fiber diagonal plywood layer; The gas-retaining layer is located inside the reinforced roll layer.
[0007] In one embodiment, the air-retaining layer is bent in the opposite direction on both sides and at least partially and alternately stacked at the center of the tire.
[0008] In one embodiment, the air-retaining layer is covered with fasteners on its inner side near the flared edge of the tire.
[0009] In one embodiment, the outer side of the air-retaining layer near the flared edge of the tire is further provided with tire bead anti-friction rubber.
[0010] In one embodiment, the tread layer has guide grooves near both sides of the tire, the guide grooves comprising multiple parallel, wavy sections.
[0011] In one embodiment, the tread layer further includes guide patterns, which include multiple alternating oblique patterns distributed on both sides of the tread and inclined toward the center of the tire.
[0012] Compared with the prior art, the beneficial effects of this utility model include at least the following: The reinforcing layer wraps around both sides of the tire and is positioned sequentially relative to the top of the tire. This fully covers the buffer layer, giving it greater elastic cushioning performance when in contact with the ground. In addition, the reinforcing layer uses a cotton fiber bias-ply cord layer, which significantly improves the tire cavity and prevents tire blowouts at high speeds. Attached Figure Description

[0014] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided to make the present invention more comprehensive and complete, and to fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore repeated descriptions of them will be omitted.
[0015] The terms used to describe position and direction in this utility model are illustrated with the accompanying drawings, but changes can be made as needed, and all such changes are included within the scope of protection of this utility model.
[0016] Reference Figure 1-2This invention provides a puncture-resistant tubeless road bicycle tire. The tire has the following components arranged sequentially in the thickness direction at its center: a tread layer 1, a reinforcing layer 2, a buffer layer 3, and an air-retaining layer 4. The reinforcing layer 2 covers the buffer layer 3, and the buffer layer 3 has a uniformly decreasing thickness at its edges as it extends towards both sides of the tire. The reinforcing layer 2 is bent backwards near the edges of both sides of the tire and then attached to the top of the buffer layer 3 with its inner side facing outwards. The reinforcing layer 2 is a cotton fiber diagonal plywood layer. The air-retaining layer 4 is located inside the reinforcing layer 2. The tread layer 1, as the outermost layer in contact with the ground, is primarily made of rubber, while the air-retaining layer 4 covers the inner side of the tire, protecting it. The use of a cotton fiber diagonal plywood layer and the reinforcing layer 2 connected to the top of the buffer layer 3 fully covers it, preventing the tire tread or sidewall from rupturing and causing a blowout at high speeds. The fully covered buffer layer 3 can significantly offset impacts and protect the tire's air chamber.
[0017] Preferably, the two sides of the air-retaining layer 4 are bent in the opposite direction and at least partially and alternately layered at the center of the tire. The intersection of the top two sides of the air-retaining layer 4, preferably the area of the intersection portion, can be connected with an adhesive to enhance the protection of the air-retaining layer 4. Furthermore, the thickness decreases at the edges, ensuring that the final air-retaining layer 4 maintains its basic original shape after connection. This prevents unevenness caused by bulges from concentrating wear and reducing tire life.
[0018] Preferably, the inner side of the air-retaining layer 4 near the flared edge of the tire is covered with fasteners 5. The fasteners 5 are made of steel wire rope, which serves as a supporting skeleton inside the tire to improve the airtight connection between the tire and the rim.
[0019] Preferably, the outer side of the air-retaining layer 4 near the flared edge of the tire is also provided with tire bead anti-scratch rubber 6. This makes the installation process easier and smoother, and most importantly, it can effectively prevent scratches or cuts to the tire bead and rim due to dry friction, protecting the wheelset and tire.
[0020] Preferably, the tread layer 1 has guide patterns 7 near both sides of the tire, and the guide patterns 7 include multiple parallel wavy sections. The structure of the guide patterns 7 is, for example, W or V shaped, and the parallel sections are multiple parallel patterns of varying lengths. Using guide patterns 7 can effectively improve the grip of the tire sidewall and maintain good tire guiding ability.
[0021] Preferably, the tread layer 1 further includes guide grooves 8, which consist of multiple alternating inclined grooves distributed on both sides of the tread and inclined towards the center of the tire. The guide grooves 8 can reduce rolling resistance and enhance wet stability.
[0022] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and alterations to the above embodiments within the scope of the present invention without departing from the principles and spirit of the present invention, and all such changes should fall within the protection scope of the claims of the present invention.
