Description

Technical Field

[0001] The present invention belongs to the technical field of tires, and particularly relates to an energy-saving tire with low rolling resistance and wear resistance. Background Art

[0002] An energy-saving tire refers to a radial tire that has low rolling resistance, low fuel consumption, and low exhaust emissions due to the application of new materials and designs. The structural design of the radial tire makes the tire more evenly stressed during driving, and the wear is also relatively uniform, and it is not easy to have local excessive wear. Its rubber formula usually has better wear resistance and anti-aging performance, making the tire have better wear resistance and a long service life. However, the sidewall of this kind of tire is relatively thin, which is to meet its special structural and performance requirements. This means that when the sidewall is subjected to external force impact, it is more likely to have problems such as breakage and bulging, and its compressive wear resistance is poor. Especially when passing through a potholed road surface or colliding with obstacles such as curbstones, the driver needs to be extra careful.

[0003] For this reason, Chinese Patent No. CN2424950Y discloses a new type of bead structure load-carrying radial tire, which mainly consists of a crown, a sidewall, a bead, etc. The bead wire wrapping cloth, the carcass wire cord fabric, the bead wire ring and the wire winding cloth, the bead wear-resistant rubber strip airtight layer film, and the bead filler rubber strip form a new type of bead. After vulcanization by a molding machine and a vulcanizing machine, the product is obtained, which enhances the stiffness and strength of the tire, improves the performance of the bead, and increases the driving mileage of the tire.

[0004] However, the above device cannot effectively reinforce the sidewall, and its compressive wear resistance is poor. When subjected to external force impact, it is easy to have a breakage phenomenon. Summary of the Invention

[0005] Aiming at the problems existing in the prior art, the present invention provides an energy-saving tire with low rolling resistance and wear resistance, which has the advantages of structurally strengthening the sidewall, making the whole tire more solid, being able to better resist road surface wear during driving, improving wear resistance, reducing the risk of tire blowout, and extending the service life of the tire, and solves the problems that the sidewall cannot be effectively reinforced in the prior art, the compressive wear resistance is poor, and it is easy to have a breakage phenomenon when subjected to external force impact.

[0006] The present invention is realized as follows: An energy-saving tire with low rolling resistance and wear resistance includes a tire body and a wheel hub. The tire body includes a crown portion, a shoulder portion, and a sidewall portion. The inner wall of the tire body is fixedly coated with a protective member. The protective member includes a nylon belt protection layer, a steel wire protection layer, and a cord protection layer. A cavity portion is provided inside the sidewall portion, and a reinforcing member is fixedly installed on the cavity portion. The reinforcing member includes a reinforcing rubber ring and a reinforcing support frame, and the reinforcing support frame is fixedly connected between the reinforcing rubber rings.

[0007] With this setting, through the protective member and the reinforcing member, the structure is strengthened from the inside and the sidewall of the tire, making the whole tire more robust, better able to resist road surface wear during driving, improving the wear resistance, reducing the risk of tire blowout, and extending the service life of the tire.

[0008] Preferably in the present invention, the outer surface of the tire body is fixedly connected with tread blocks, main grooves and auxiliary grooves are embedded in the crown part, and inclined grooves are embedded in the shoulder part.

[0009] With this setting, it is convenient to quickly drain water on a wet and slippery road surface, reduce the risk of side slip, increase the grip, improve the friction between the tire and the ground, adapt to different road conditions, conveniently reduce noise, absorb vibrations to reduce in-vehicle noise, conveniently dissipate heat and cool down, and promote air circulation, thereby being beneficial to reducing the energy consumption during vehicle driving, improving driving safety and at the same time being beneficial to extending the service life of the tire.

[0010] Preferably in the present invention, the main grooves are arranged in an annular structure along the surface of the tire body, the auxiliary grooves are arranged in an inclined structure and their ends extend to the shoulder part, and the auxiliary grooves and the inclined grooves are arranged in an alternating manner.

[0011] With this setting, the inclined auxiliary grooves can cause more edges and protrusions to be generated when the tire contacts the ground, increasing the friction between the tire and the ground, and providing better grip during acceleration, braking and turning. The alternating arrangement of the grooves makes the tread blocks on the tire surface form a more complex shape, and more tread blocks can contact the ground in different driving directions and road conditions, enhancing the grip performance of the tire, improving the stability and controllability of the vehicle on various road surfaces, enabling the tire to deform and fit the ground better when turning, improving the lateral support force of the tire, making the vehicle steering more sensitive and accurate, and enhancing the handling performance of the vehicle.

[0012] Preferably in the present invention, rubber convex ribs are fixedly connected to the outer surface of the sidewall part, and several rubber convex ribs are provided and evenly distributed in an annular array.

[0013] With this setting, it is beneficial to enhance the protection of the outer surface of the sidewall part, conducive to reducing the scratching and collision damage of the sidewall part, conveniently improving the grip effect, and increasing the friction and lateral support.

[0014] Preferably in the present invention, the nylon belt protection layer is fixedly coated on the inner walls of the crown part and the shoulder part, the steel wire protection layer is fixedly coated on the surface of the nylon belt protection layer, the cord protection layer is fixedly coated on the surface of the steel wire protection layer, and the cord protection layer extends to the inner wall of the sidewall part and is fixedly coated therewith, and an airtight rubber layer is fixedly coated between the surface of the cord protection layer and the inner wall of the tire body.

[0015] Through this setting, the multi-layer structure forms a solid protection system, which enhances the structural strength of the tire, improves the load-bearing capacity, and evenly disperses stress. It can effectively reduce damage and cuts on the tire surface and extend the service life of the tire. The airtight rubber layer can prevent air leakage inside the tire and maintain the tire's air pressure stable, thereby improving the durability of the tire.

[0016] As a preferred embodiment of the present invention, the reinforcement rubber rings are provided in plurality and fixedly connected to the cavity portion, the reinforcement support frames are provided in plurality and are evenly distributed in a ring array between the reinforcement rubber rings, rubber support plates are fixedly connected to the inner ends of the reinforcement support frames, and the reinforcement support frames are made of rubber material.

[0017] Through this arrangement, the cavity portion, the reinforced rubber ring, the reinforced support frame and the rubber support plate cooperate with each other, which is beneficial to enhancing the strength and toughness of the sidewall portion, improving its ability to withstand lateral force and impact force, and making the sidewall less likely to deform or rupture excessively. The cavity portion can reduce the weight of the sidewall portion on the one hand, and provide deformation space on the other hand. When the sidewall is subjected to external force, it absorbs and disperses part of the impact force through deformation, thereby reducing the pressure on the internal structure of the tire, reducing the possibility of a tire blowout caused by excessive pressure, and facilitating the circulation of air inside the tire, accelerating heat dissipation, which is beneficial to reducing the risk of a tire blowout.

[0018] As a preferred embodiment of the present invention, a clearance groove is provided between the cord protection layer and the airtight rubber layer, the upper and lower parts of the reinforcement support frame are provided in the clearance groove, and the end of the reinforcement support frame extends to the inside of the tire body.

[0019] This arrangement facilitates the installation of the reinforcement support frame and facilitates the end of the reinforcement support frame to extend into the tire.

[0020] As a preferred embodiment of the present invention, uniformly distributed buffer rubber columns are fixedly connected to the surface of the hub, the buffer rubber columns and the reinforcement support frame are arranged in a one-to-one correspondence, and the buffer rubber columns abut against the reinforcement support frame.

[0021] Through this arrangement, after the wheel hub and the tire body are assembled, the buffer rubber columns will abut against the corresponding reinforced support frames one by one. On the one hand, the reinforced support frame cooperates with the cavity portion, the reinforced rubber ring and the rubber support plate to enhance the structural strength and pressure resistance of the sidewall portion and reduce the risk of sidewall damage. On the other hand, it can cooperate with the buffer rubber column to enhance the tire's enhanced pressure resistance, so that the tire can further buffer and absorb the pressure exerted on the road during driving, improve the stability of the tire during driving, make the connection between the tire and the wheel hub more stable, suppress the tire's swaying and shaking, ensure the vehicle's handling performance and driving stability, and extend the service life of the tire.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows: The structure of the interior and sidewall of the tire is strengthened, making the tire as a whole more robust, better able to resist road surface wear during driving, improving the wear resistance performance, reducing the risk of tire blowout, and extending the service life of the tire.

[0023] Through the mutual cooperation of the cavity part, the reinforced rubber ring, the reinforced support frame, and the rubber support plate, it is beneficial to enhance the strength and toughness of the sidewall part, improve its bearing capacity for lateral force and impact force, and make the sidewall not easily deform or rupture excessively. On the one hand, the cavity part can reduce the weight of the sidewall part, and on the other hand, it can provide a deformation space, reduce the pressure borne by the internal structure of the tire, reduce the possibility of tire blowout caused by excessive pressure, and contribute to the air circulation inside the tire, accelerate heat dissipation, and is beneficial to reducing the risk of tire blowout.

[0024] The reinforced support frame cooperates with the buffer rubber column to enhance the compressive capacity of the tire reinforcement, enabling the tire to further buffer and absorb the pressure exerted on the road surface during driving, improving the stability of the tire during driving, making the connection between the tire and the wheel hub more stable, suppressing tire yaw and wobbling, ensuring the vehicle handling performance and driving stability, and extending the service life of the tire.

[0034] The structure of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0035] Refer to Figures 1 to 7 As shown, an energy-saving tire with low rolling resistance and wear resistance provided by an embodiment of the present invention includes a tire body 1 and a wheel hub 2. The tire body 1 includes a crown part 101, a shoulder part 102 and a sidewall part 103. The inner wall of the tire body 1 is fixedly coated with a protective part 3. The protective part 3 includes a nylon belt protection layer 301, a steel wire protection layer 302 and a cord protection layer 303. A cavity part 4 is formed inside the sidewall part 103, and a reinforcing part is fixedly installed on the cavity part 4. The reinforcing part includes a reinforcing rubber ring 5 and a reinforcing support frame 6, and the reinforcing support frame 6 is fixedly connected between the reinforcing rubber rings 5.

[0036] Adopting the above scheme, through the protective part 3 and the reinforcing part, the structure is strengthened from the inside of the tire and the sidewall, making the whole tire more solid, being able to better resist the wear of the road surface during driving, improving the wear resistance, reducing the risk of tire blowout, and extending the service life of the tire.

[0037] Specifically, a pattern block 8 is fixedly connected to the outer surface of the tire body 1, a main groove 9 and an auxiliary groove 10 are embedded on the crown part 101, and an oblique groove 11 is embedded on the shoulder part 102.

[0038] Adopting the above scheme, it is convenient to quickly drain water on a wet and slippery road surface, reduce the risk of side slip, increase the grip, improve the friction between the tire and the ground, adapt to different road conditions, facilitate noise reduction, absorb vibration to reduce the noise inside the vehicle, facilitate heat dissipation and cooling, and promote air circulation, so as to be conducive to reducing the energy consumption during vehicle driving, improving driving safety and prolonging the service life of the tire at the same time.

[0039] Specifically, the main groove 9 is arranged in an annular structure along the surface of the tire body 1, the auxiliary groove 10 is arranged in an inclined structure and its end extends to the tire shoulder 102, and the auxiliary groove 10 and the inclined groove 11 are arranged alternately.

[0040] With the above solution, the inclined auxiliary groove 10 can generate more edges and protrusions when the tire contacts the ground, increasing the friction between the tire and the ground, and providing better grip during acceleration, braking, and turning. The staggered arrangement of the grooves makes the tread blocks 8 on the tire surface form a more complex shape, and more tread blocks 8 can contact the ground under different driving directions and road conditions, enhancing the grip performance of the tire, improving the stability and controllability of the vehicle on various road surfaces, enabling the tire to deform and fit the ground better during steering, increasing the lateral support force of the tire, making the vehicle steering more sensitive and precise, and improving the handling performance of the vehicle.

[0041] Specifically, rubber ridges 7 are fixedly connected to the outer surface of the tire sidewall 103, and several rubber ridges 7 are provided and evenly distributed in a circular array.

[0042] With the above solution, it is beneficial to enhance the protection of the outer surface of the tire sidewall 103, reduce the scratching and collision damage of the tire sidewall 103, facilitate improving the grip effect, and increase the friction and lateral support.

[0043] Specifically, the nylon belt protection layer 301 is fixedly wrapped on the inner walls of the tire crown 101 and the tire shoulder 102, the steel wire protection layer 302 is fixedly wrapped on the surface of the nylon belt protection layer 301, the cord protection layer 303 is fixedly wrapped on the surface of the steel wire protection layer 302, and the cord protection layer 303 extends to the inner wall of the tire sidewall 103 and is fixedly wrapped therewith. An airtight rubber layer 304 is fixedly wrapped between the surface of the cord protection layer 303 and the inner wall of the tire body 1.

[0044] With the above solution, the multi-layer structure forms a strong protection system, enhancing the structural strength of the tire, improving the load-bearing capacity, evenly dispersing stress, effectively reducing the occurrence of damage, cuts, etc. on the tire surface, extending the service life of the tire.

The cavity portion 4 can reduce the weight of the sidewall portion 103 on the one hand, and provide deformation space on the other hand. When the sidewall is subjected to external force, it absorbs and disperses part of the impact force through deformation, thereby reducing the pressure on the internal structure of the tire, reducing the possibility of tire blowout caused by excessive pressure, and facilitating the circulation of air inside the tire, accelerating heat dissipation, which is beneficial to reducing the risk of tire blowout.

[0049] Specifically, uniformly distributed buffer rubber columns 201 are fixedly connected to the surface of the wheel hub 2 , and the buffer rubber columns 201 and the reinforcement support frame 6 are arranged in a one-to-one correspondence, and the buffer rubber columns 201 abut against the reinforcement support frame 6 .

[0050] By adopting the above scheme, after the wheel hub 2 and the tire body 1 are assembled, the buffer rubber columns 201 will abut against the corresponding reinforcement support frames 6 one by one. On the one hand, the reinforcement support frame 6 cooperates with the cavity portion 4, the reinforcement rubber ring 5 and the rubber support plate 601 to enhance the structural strength and pressure resistance of the sidewall portion 103 and reduce the risk of sidewall damage. On the other hand, it can cooperate with the buffer rubber column 201 to enhance the pressure resistance of the tire, so that the tire can further buffer and absorb the pressure exerted on the road surface during driving, improve the stability of the tire during driving, make the connection between the tire and the wheel hub 2 more stable, suppress the tire's yaw and shaking, ensure the vehicle's handling performance and driving stability, and extend the service life of the tire.
