Description

Technical Field

[0001] This utility model relates to the field of motorcycle tire technology, specifically to a non-slip and wear-resistant motorcycle tire. Background Technology

[0002] Motorcycle tires are made of durable rubber, which is strong yet elastic. They are in direct contact with the ground and protect the inner tube from damage.

[0003] Motorcycle tires have multiple anti-slip ridges on their surface to prevent slippage when riding on high-speed or wet roads. However, existing motorcycle tire anti-slip ridges are made of only a single type of rubber, which results in insufficient wear resistance and affects the durability of the anti-slip effect.

[0004] Therefore, there is an urgent need for a non-slip and wear-resistant motorcycle tire to solve the above problems. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a non-slip and wear-resistant motorcycle tire, including an outer tire bead fitted onto a wheel hub, and multiple sets of anti-slip ridges arranged symmetrically in pairs on the surface of the outer tire bead. Each of the anti-slip ridges is composed of a high-friction coefficient surface layer, an elastic buffer support middle layer, and an interface bonding reinforcement bottom layer. The interface bonding reinforcement bottom layer is connected to the outer tire bead, and the high-friction coefficient surface layer is in contact with the ground. The opposite ends of two opposing anti-slip ridges are beveled with water-guiding angles.

[0006] The high friction coefficient surface layer is composed of nitrile rubber, silicon carbide particles and graphene nanosheets, with the nitrile rubber and graphene nanosheets intertwined in an "S" shape on the outside of the graphene nanosheets.

[0007] The elastic cushioning support middle layer is composed of thermoplastic polyurethane and chopped glass fiber filaments, which are interwoven in both the transverse and longitudinal directions.

[0008] The interface is made of reinforced chloroprene rubber combined with a silane coupling agent.

[0009] The outer tire bead is provided with a water channel between two opposing anti-slip ridges.

[0010] The anti-slip ridges arranged in a ring are connected to each other by multiple reinforcing strips.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This utility model of an anti-slip and wear-resistant motorcycle tire utilizes a three-layer composite material structure. The high-friction coefficient surface layer provides initial anti-slip performance, the elastic buffer support middle layer reduces surface wear through the support of TPU and glass fiber, and the interface bonding reinforces the bottom layer to ensure long-term structural stability, forming a closed-loop design of "anti-slip-wear-connection". Through the complementary properties of the materials, the anti-slip and wear-resistant properties of the motorcycle tire are synergistically improved. This ensures the anti-slip performance of the motorcycle tire while improving the wear resistance of the anti-slip ridges, thereby enhancing the durability of the anti-slip performance of the motorcycle tire.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1

[0021] Please see Figures 1-5The figure shows a type of anti-slip and wear-resistant motorcycle tire, including an outer tire bead 1 fitted onto the wheel hub, and multiple sets of anti-slip ridges 2 arranged symmetrically in pairs on the surface of the outer tire bead 1. Each anti-slip ridge 2 is composed of a high-friction coefficient surface layer 201, an elastic buffer support middle layer 202, and an interface bonding reinforcement bottom layer 203. The interface bonding reinforcement bottom layer 203 is connected to the outer tire bead 1, and the high-friction coefficient surface layer 201 is in contact with the ground. The opposite ends of two anti-slip ridges 2 are beveled with water-guiding bevels.

[0022] It should be noted that by employing a three-layer composite material, the high-friction coefficient surface layer 201 provides initial anti-slip performance, the elastic buffer support middle layer 202 reduces surface wear through the support of TPU and glass fiber, and the interface bonding reinforced bottom layer 203 ensures long-term structural stability, forming a closed-loop design of "anti-slip-wear-connection". Thus, with the complementary properties of the materials, the anti-slip and wear resistance of the motorcycle tire are synergistically improved. This ensures the anti-slip performance of the motorcycle tire while improving the wear resistance of the anti-slip ridge 2, thereby enhancing the durability of the anti-slip performance of the motorcycle tire.

[0023] Please see Figure 3 and Figure 5 The high friction coefficient surface layer 201 shown in the figure is composed of nitrile rubber 2011, silicon carbide particles 2012 and graphene nanosheets 2013. The nitrile rubber 2011 and graphene nanosheets 2013 are intertwined in an "S" shape on the outside of the graphene nanosheets 2013.

[0024] It should be noted here that nitrile rubber 2011 itself has good oil resistance and elasticity, providing basic frictional properties;

[0025] Silicon carbide particles 2012 (with a Mohs hardness of 9.5) are evenly distributed on the surface, forming microscopic hard protrusions that embed into the ground to increase the interlocking ability and improve the coefficient of friction on dry ground.

[0026] The two-dimensional layered structure of graphene nanosheets in 2013 enhances the surface wear resistance, while the "S"-shaped winding structure can elastically deform under stress, adapting to different road surface roughness and maintaining continuous frictional contact.

[0027] Please see Figure 3 and Figure 4 The elastic buffer support middle layer 202 shown in the figure is composed of thermoplastic polyurethane 2021 and glass fiber chopped strands 2022, and the thermoplastic polyurethane 2021 and glass fiber chopped strands 2022 are interwoven in the transverse and longitudinal directions.

[0028] It should be noted here that the elastic buffer support middle layer 202 is set up with the use of thermoplastic polyurethane 2021 with an elastic modulus of 150MPa, which can absorb the impact energy of the road surface, reduce the shedding of surface silicon carbide particles 2012 due to impact, and extend the anti-skid life.

[0029] The glass fiber chopped strands 2022 form a "skeleton support" structure, which limits the excessive deformation of the thermoplastic polyurethane 2021, maintains the rigidity of the anti-slip ridges 2, and avoids structural collapse caused by long-term compression, thereby maintaining the durability of the surface friction performance.

[0030] Please see Figure 3 The interface shown in the diagram is made of reinforced 203 chloroprene rubber combined with a silane coupling agent.

[0031] It should be noted here that: the interface combined with the enhanced bottom layer 203 setting, and the bottom layer design of neoprene rubber and silane coupling agent, solves the problem of adhesion strength between multi-layer materials, ensuring the long-term stable operation of the composite structure.

[0032] Working principle: Existing tire anti-slip ridges 2 mostly use a single rubber material, and the coefficient of friction decreases rapidly with wear. Moreover, rubber is prone to aging and has poor impact resistance. This application adopts a three-layer composite material to work together. The high-friction coefficient surface layer 201 provides initial anti-slip performance, the elastic buffer support middle layer 202 reduces surface wear through the support of TPU and glass fiber, and the interface bonding reinforced bottom layer 203 ensures long-term structural stability, forming a closed-loop design of "anti-slip-wear-connection". Thus, with the complementary properties of the materials, the anti-slip and wear resistance of the motorcycle tire are synergistically improved. This ensures the anti-slip performance of the motorcycle tire while improving the wear resistance of the anti-slip ridge 2, thereby improving the durability of the anti-slip performance of the motorcycle tire.

[0033] Example 2

[0034] Please see Figure 2 This embodiment further illustrates Example 1, in which the outer tire bead 1 in the figure is provided with a water channel 3 between two opposing anti-slip ridges 2;

[0035] It should be noted that the inclined water diversion channel guides rainwater from the road surface to flow quickly into the water diversion channel 3. The water diversion channel 3 is continuously distributed in a ring shape with a trapezoidal cross-section, which can improve drainage efficiency, reduce the "water drift effect" when driving on wetlands, ensure direct contact between the surface and the ground, and maintain the wetland friction coefficient.

[0036] Example 3

[0037] Please see Figure 2 This embodiment is a further explanation of other embodiments. In the figure, the anti-slip protrusions 2 arranged in a ring are connected to each other by multiple reinforcing strips 4.

[0038] It should be noted that the annular anti-skid ridges 2 are connected by multiple reinforcing strips 4. The reinforcing strips 4 are made of the same material as the outer tire bead and have a rectangular cross-section. The reinforcing strips 4 connect the independent anti-skid ridges 2 into an overall network structure, which improves the tread rigidity and reduces the torsional deformation of the anti-skid ridges 2 under high loads. When an anti-skid ridge 2 is impacted, the reinforcing strips 4 can distribute the load to the adjacent ridges, avoiding excessive wear in certain areas and making the overall wear more uniform.

[0039] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
