Description

Technical Field

[0001] This utility model relates to the field of motorcycle inner tube technology, and in particular to a motorcycle explosion-proof inner tube. Background Technology

[0002] Traditional motorcycle inner tubes are typically made of a single rubber material, resulting in poor puncture resistance. They are easily punctured by sharp objects on the road, such as nails or glass shards, causing a sudden loss of air. This sudden pressure loss can cause the vehicle to lose balance instantly, easily leading to serious traffic accidents and posing a significant threat to the rider's life. However, existing run-flat inner tubes for motorcycles still suffer from poor wear resistance and cannot be quickly and temporarily sealed after a puncture.

[0003] Therefore, it is essential to invent a motorcycle explosion-proof inner tube. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a motorcycle run-flat inner tube, solving the issue that existing motorcycle run-flat inner tubes still suffer from poor wear resistance and cannot quickly provide temporary sealing when the tire is punctured. A motorcycle run-flat inner tube includes a tire body, an outer tire contact surface, a stress-bearing reinforcing ring, and an auxiliary reinforcing ring. The outer tire contact surface is fixedly installed on the outer surface of the tire body, and the stress-bearing reinforcing ring is bonded and fixedly installed on the inner wall of the tire body. The auxiliary reinforcing ring is bonded and fixedly installed on the inner wall of the tire body; the auxiliary reinforcing ring is located outside the stress-bearing reinforcing ring.

[0005] The tire body includes a load-bearing outer layer, a reinforcing inner layer, and a self-compensating layer, with the reinforcing inner layer bonded to the inner wall of the load-bearing outer layer and the self-compensating layer bonded to the inner wall of the reinforcing inner layer.

[0006] The stress-bearing reinforcing ring includes a connecting arc surface, a mounting plane, an elastic connecting piece, and a puncture-proof gasket. The connecting arc surface is bonded and fixedly installed on the inner wall of the tire body, and the mounting plane is located on the opposite side of the connecting arc surface. The elastic connecting piece is bonded to the surface of the mounting plane, and the puncture-proof gasket is installed at one end of the elastic connecting piece.

[0007] The tire body uses a rubber inner tube, and an annular inflation zone is provided inside the tire body. The inflation zone inside the tire body is not in the exact center of the tire body, but is biased towards the center, so that the thickness of the outer side of the tire body is greater than the thickness of the inner side. The reinforcing inner layer is a rubber layer with metal wires inside, and the self-compensating layer is a soft rubber layer.

[0008] The stress-bearing reinforcing ring, through its internal connecting arc surface and mounting plane, can fill part of the inflation zone inside the tire body, so that the inner wall of the tire body, which is arc-shaped in both directions, forms a ring-shaped surface; the elastic connecting piece and the puncture-proof pad are made of several scale-like rubber sheets. If the tire body is punctured, the puncture-proof pad will adhere tightly to the puncture site under the action of air pressure difference; the internal structure of the stress-bearing reinforcing ring is completely consistent with that of the auxiliary reinforcing ring.

[0009] Compared with the prior art, the present invention has the following beneficial effects: 1. The tire body of this utility model is designed with a unique three-layer composite structure, consisting of an outer layer providing basic strength and wear resistance, a reinforced inner layer with built-in metal wires to greatly enhance tear resistance, and a self-compensating layer that enhances air tightness and elasticity. Together, these layers provide the main structural support, toughness, and pressure resistance. At the same time, its deliberately asymmetrical design, which is biased towards the center, makes the outer side of the tire body thicker than the inner side, thereby focusing on strengthening the protection of the vulnerable sidewalls and providing a key mounting base for the reinforcing ring and auxiliary reinforcing ring in the stress zone.

[0010] 2. The reinforcing ring in the stress zone of this utility model is bonded to the inner wall of the tire body by connecting the arc surface and the mounting plane, filling part of the inflation zone and transforming the arc-shaped inner wall into a ring-shaped plane, thereby providing local structural reinforcement; several scale-like puncture-resistant pads connected by elastic connecting pieces on it can quickly adhere to and seal the puncture when the tire body is punctured by the internal air pressure difference, and work together with the auxiliary reinforcing ring with the same structure to form an active puncture-resistant safety mechanism.

Detailed Implementation

[0016] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0017] As attached Figure 1 To be continued Figure 4 As shown.

[0018] This utility model provides a motorcycle explosion-proof inner tube, including a tire body 1, an outer tire contact surface 2, a stress-bearing reinforcing ring 3, and an auxiliary reinforcing ring 4, wherein: the outer tire contact surface 2 is fixedly installed on the outer surface of the tire body 1, and the stress-bearing reinforcing ring 3 is bonded and fixedly installed on the inner wall of the tire body 1, and the auxiliary reinforcing ring 4 is bonded and fixedly installed on the inner wall of the tire body 1; the auxiliary reinforcing ring 4 is located outside the stress-bearing reinforcing ring 3.

[0019] The tire body 1 includes a stress-bearing outer layer 11, a reinforcing inner layer 12, and a self-compensating layer 13, with the reinforcing inner layer 12 bonded to the inner wall of the stress-bearing outer layer 11 and the self-compensating layer 13 bonded to the inner wall of the reinforcing inner layer 12.

[0020] The stress-bearing reinforcing ring 3 includes a connecting arc surface 31, a mounting plane 32, an elastic connecting piece 33, and a puncture-proof pad 34. The connecting arc surface 31 is bonded and fixedly installed on the inner wall of the tire body 1, and the mounting plane 32 is located on the opposite side of the connecting arc surface 31. The elastic connecting piece 33 is bonded to the surface of the mounting plane 32, and the puncture-proof pad 34 is installed at one end of the elastic connecting piece 33.

[0021] The tire body 1 uses a rubber inner tube, and an annular inflation zone is provided inside the tire body 1. The inflation zone inside the tire body 1 is not in the exact center of the tire body 1, but is biased towards the center, so that the thickness of the outer side of the tire body 1 is greater than the thickness of the inner side; the reinforcing inner layer 12 is a rubber layer with metal wires inside, and the self-compensating layer 13 is a soft rubber layer.

[0022] The stress-bearing reinforcing ring 3, through its internal connecting arc surface 31 and mounting plane 32, can fill part of the inflation area inside the tire body 1, so that the inner wall of the tire body 1, which is arc-shaped in both directions, forms a ring-shaped surface; the elastic connecting piece 33 and the puncture-proof pad 34 are made of several scale-like rubber sheets. If the tire body 1 is punctured, the puncture-proof pad 34 will adhere tightly to the puncture site under the action of air pressure difference; the internal structure of the stress-bearing reinforcing ring 3 is completely consistent with that of the auxiliary reinforcing ring 4.

[0023] This motorcycle's run-flat inner tube 1 achieves graded protection through a composite structure. The tire body 1 adopts a three-layer design: the outer load-bearing layer 11 provides basic wear resistance, the reinforcing inner layer 12 provides skeletal support through an internal metal wire network, and the self-compensating layer 13 maintains airtightness using the properties of soft rubber. The asymmetrical structure thickens the outer tire body, significantly improving impact resistance and forming the first line of passive protection.

[0024] When a sharp object punctures the tire, the reinforcing ring 3 in the stress zone and the auxiliary reinforcing ring 4 activate the active sealing mechanism. The internal air pressure difference pushes the puncture-resistant gasket 34 to quickly seal the puncture site through the elastic connecting piece 33, while the mounting plane 32 and the connecting arc surface 31 work together to stabilize the inner wall structure. The dual rings work together to form redundant protection, ensuring that basic driving functions can still be maintained even when the tire body is damaged.

[0025] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution described in this utility model, falls within the protection scope of this utility model.
