Description

Technical Field

[0001] The utility model relates to the technical field of tires, and particularly to a low-rolling-resistance rubber tire. Background Art

[0002] A rubber tire is a tire made of rubber materials and other composite materials, and is the part of an automobile and other means of transportation (such as motorcycles, bicycles, trucks, etc.) that contacts the ground. Its main functions are to support the weight of the vehicle, provide traction, handling and comfort, and at the same time can effectively absorb vibrations and impacts.

[0003] When a rubber tire contacts the ground, it will produce a certain deformation, resulting in energy loss, thereby increasing the rolling resistance. This will affect the fuel efficiency, especially during long-distance driving, where it will more significantly increase the fuel consumption. Therefore, it is necessary to design a low-rolling-resistance rubber tire to solve the above problems. Summary of the Invention

[0004] The purpose of the utility model is to provide a low-rolling-resistance rubber tire to solve the technical problems raised in the above background art.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A low-rolling-resistance rubber tire, including a tire body, the tire body includes an outer tire layer, an intermediate layer, a liner layer and a bottom liner layer which are arranged in sequence from outside to inside. The outer tire layer is a silicone rubber layer, and its surface is provided with patterns. There is a gap formed between the intermediate layer and the liner layer. A plurality of rubber rings with an O-shaped cross-section are arranged and distributed in the gap, and a plurality of reinforcing ribs arranged in an annular array are fixedly connected in the gap. Each reinforcing rib is fixedly inserted into a plurality of rubber rings.

[0006] Preferably, the intermediate layer is a synthetic rubber layer, and its thickness is at least 3 mm.

[0007] Preferably, a reinforcing layer is provided on the inner wall of the intermediate layer, and the reinforcing layer includes a nylon layer or a polyester fiber layer.

[0008] Preferably, the liner layer includes a butyl rubber layer or a neoprene rubber layer.

[0009] Preferably, the bottom liner layer is a rubber layer, and its interior has an aramid fiber braided structure.

[0010] Preferably, the upper and lower ends of the rubber ring respectively abut against the upper and lower sides of the inner wall of the gap, and the reinforcing rib penetrates through the middle position of each rubber ring.

[0011] The technical solution provided by the utility model, compared with the prior art, has the following beneficial effects:

[0012] The utility model can effectively absorb impact force through multiple rubber rings in the form of O-shaped structures in the gaps, provide better shock absorption effect, and can help evenly distribute the load borne by the tire, reduce local stress concentration. The presence of the reinforcing ribs can increase the lateral support force of the tire when turning or changing lanes, help maintain the shape of the tire, and prevent deformation at high speeds, thereby achieving the purpose of reducing the rolling resistance generated by the tire during driving.

[0013] In the utility model, the reinforcing layer is designed as a nylon layer or a polyester fiber layer. The polyester fiber layer has good strength and wear resistance, and its characteristics of being lightweight and having high tensile strength can effectively improve the stability and durability of the tire. If the nylon layer is selected, it has more excellent tear resistance and toughness, and is suitable for high-performance tires and off-road tires.

[0014] The gaps designed in the utility model play a role in reducing the material consumption and the overall weight of the tire, thereby improving the fuel efficiency and the acceleration performance of the vehicle, and can further improve the shock absorption performance of the tire, enhance the comfort, and reduce the transmission of road surface bumps to the interior of the vehicle.

[0020] Next, the technical solutions in the embodiments of the utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the utility model.

[0021] Obviously, many specific details are set forth in the following description in order to fully understand the utility model. However, the utility model can also be implemented in other ways different from those described herein. Therefore, the utility model is not limited by the limitations of the specific embodiments disclosed in the following specification.

[0022] Please refer to Figures 1-4, the present utility model provides a low rolling resistance rubber tire, which includes a tire body 1. The tire body 1 includes a tread layer 11, an intermediate layer 12, an inner liner layer 17 and a bottom liner layer 18 arranged from outside to inside in sequence. The tread layer 11 is a silicone rubber layer with patterns on its surface. There is a gap 14 formed between the intermediate layer 12 and the inner liner layer 17. Multiple rubber rings 15 with an O-shaped cross-section are arranged and distributed in the gap 14, and multiple reinforcing ribs 16 arranged in a circular array are fixedly connected in the gap 14. Each reinforcing rib 16 is fixedly inserted into multiple rubber rings 15. Through such a design, multiple O-shaped rubber rings 15 in the gap 14 can effectively absorb impact force, provide a better shock absorption effect, and can help evenly distribute the load borne by the tire, reduce local stress concentration. The existence of the reinforcing ribs 16 can increase the lateral support force of the tire when turning or changing lanes, help maintain the shape of the tire, and prevent deformation at high speeds, so as to achieve the purpose of reducing the rolling resistance generated by the tire during driving.

[0023] Specifically, the intermediate layer 12 is a synthetic rubber layer with a thickness of at least 3 mm. The synthetic rubber layer has good elasticity and wear resistance, and can effectively absorb impact and provide a comfortable driving experience.

[0024] It should be noted that a reinforcing layer 13 is provided on the inner wall of the intermediate layer 12. The reinforcing layer 13 includes a nylon layer or a polyester fiber layer. The polyester fiber layer has good strength and wear resistance, and its characteristics of being lightweight and having a high tensile strength can effectively improve the stability and durability of the tire. If a nylon layer is selected, it has more excellent tear resistance and toughness, and is suitable for high-performance tires and off-road tires.

[0025] At the same time, the inner liner layer 17 includes a butyl rubber layer or a neoprene rubber layer. The butyl rubber layer has excellent airtightness and low gas permeability, and can effectively prevent gas leakage, which is suitable for use in the inner liner layer. Although the neoprene rubber layer has inferior airtightness compared to the butyl rubber, it has good heat resistance and still performs well in a specific high-temperature environment.

[0026] Furthermore, the bottom liner layer 18 is a rubber layer with an aramid fiber braided structure inside, so as to improve the durability and tear resistance of the tire and provide a strengthened and reliable bottom tire for the tire.

[0027] Please refer to Figure 2, the upper and lower ends of the rubber ring 15 respectively abut against the upper and lower sides of the inner wall of the gap 14, and the reinforcing ribs 16 are inserted in the middle positions of each rubber ring 15. The existence of the gap 14 serves to reduce the material consumption and the overall weight of the tire, thereby improving the fuel efficiency and the acceleration performance of the vehicle, and can further improve the shock absorption performance of the tire, enhance the comfort, and reduce the transmission of road surface bumps to the interior of the vehicle. The rubber ring 15 can provide good support for the entire gap 14, and the reinforcing ribs 16 are used to strengthen the rubber ring 15 itself to prevent it from collapsing and deforming, which can achieve a more effective effect of reducing the rolling resistance.

[0028] The preferred embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the specific details in the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solutions of the present invention, and these simple modifications all fall within the protection scope of the present invention.

[0029] In addition, it should be noted that, among the various specific technical features described in the above specific embodiments, they can be combined in any appropriate manner without contradiction. To avoid unnecessary repetition, the present invention will not separately describe various possible combination methods.

[0030] In addition, any combination can be made between various different embodiments of the present invention as long as it does not violate the idea of the present invention, and it should also be regarded as the content disclosed by the present invention.
