Description
Technical Field
[0001] The utility model belongs to the technical field of automobile tires, and in particular relates to a heat dissipation type new energy automobile tire. Background Art
[0002] Tires are an essential part of various transport vehicles, supporting the forward movement of the vehicle. When the vehicle is driving, the tires have to bear loads, forces and high temperatures, which requires the tires to have high wear resistance, cushioning performance, anti-skid performance and heat dissipation performance.
[0003] In real life, when vehicles are driving at high speeds and for long periods of time, the temperature of the tire tread is high due to poor heat dissipation performance, which can easily cause tire blowouts, safety accidents, and waste. The tires will generate heat due to friction and deformation during driving. This heat is mainly concentrated in the tread and shoulder, which means that under normal driving conditions, the temperature of the tread is usually higher than the sidewall. In addition, the temperature of the tire is also affected by the speed of the vehicle, and high-speed driving will cause the tire temperature to rise. Especially when new energy vehicles are starting, the acceleration can reach a peak instantly, and the tire's grip ability is required to be higher, which will increase the friction between the tire and the ground. The temperature of the tread is high, which can easily cause the tread to age faster, accelerate wear, and easily cause punctures and blowouts. Utility Model Content
[0004] In order to solve the above problems, the utility model proposes a heat-dissipating new energy vehicle tire. The tire transfers the heat of the tread to the sidewall by arranging heat-dissipating grooves and heat conductors, thereby effectively and quickly reducing the tread temperature, reducing the aging rate, effectively reducing the risk of punctures and blowouts, improving driving safety, and increasing the service life of the tire, providing a new idea for reducing the temperature of the tread.
[0005] The technical solution of the utility model is as follows:
[0006] A new type of automobile tire comprises a tire body, wherein the tire body comprises a tread, a shoulder and a sidewall, and heat dissipation grooves are arranged on the surface layers of the tread, the shoulder and the sidewall, and a heat conductor is arranged in the heat dissipation groove, and the heat conductor is fixedly connected to the heat dissipation groove; the surface layers of the tread, the shoulder and the sidewall are silicone rubber protective layers, and the heat dissipation grooves are arranged on the silicone rubber protective layer.
[0007] Preferably, at least four heat dissipation grooves are provided.
[0008] Further preferably, the heat dissipation grooves are evenly arranged on the tire body.
[0009] Preferably, the heat conductor comprises a heat conducting material layer and a rubber material coating layer, the heat conducting material layer contacts the bottom of the heat dissipation groove, and the rubber coating layer is fixedly connected to the heat dissipation groove.
[0010] Further preferably, the thermal conductive material layer is selected from graphene fiber material. More preferably, the graphene fiber material can specifically be selected from graphene fiber bundles, graphene fiber fabrics, or composite fiber bundles or fabrics of graphene fibers and other fibers (cotton fibers, polyurethane, polyester fibers, or modal, etc.).
[0011] Further preferably, the heat-conducting material layer arranged on the tread and shoulder has no contact with the outside air, and heat dissipation holes are arranged on the rubber material coating layer in the heat conductor arranged on the sidewall, and the heat-conducting material layer arranged on the sidewall is in contact with the outside air through the heat dissipation holes.
[0012] Preferably, the distance between the outermost layer of the heat conductor and the center of the tire body is smaller than the distance between the outermost layer of the tread and the center of the tire body, and the distance between the outermost layer of the heat conductor and the center of the tire body is smaller than the distance between the outermost layer of the shoulder and the center of the tire body.
[0013] Preferably, the distance between the outermost layer of the heat conductor and the center of the tire body is equal to the distance between the outermost layer of the tread and the center of the tire body, and the distance between the outermost layer of the heat conductor and the center of the tire body is equal to the distance between the outermost layer of the shoulder and the center of the tire body.
[0014] Further preferably, the outermost layer of the heat conductor is recessed in the outermost layer of the sidewall. When the outermost layer of the heat conductor is recessed in the outermost layer of the tire body, the tire has more contact area with the outside world, which is beneficial to heat dissipation and drainage.
[0015] Further preferably, the outermost layer of the heat conductor protrudes from the outermost layer of the sidewall, or the outermost layer of the heat conductor is flush with the outermost layer of the sidewall. The outermost layer of the heat conductor protrudes from the outermost layer of the sidewall, which can form a bulge, and can also increase the contact surface and improve the heat dissipation capacity. When the number of appropriate heat conductors is set, two heat conductors will form a large groove on the sidewall, which is conducive to placing the tire binding chain in the large groove on snowy days, helping to stabilize the chain and improve the safety of driving on snowy days.
[0016] The utility model provides a heat dissipation type new energy vehicle tire. By arranging heat dissipation grooves, the contact area between the tire and the outside air can be increased, thereby improving the heat dissipation efficiency, which is helpful to reduce the temperature accumulation of the tire when running at high speed or working for a long time, and prolonging the service life of the tire; a heat conductor is arranged in the groove, and the temperature of the tread can be quickly transferred to the sidewall, which is conducive to quickly cooling the tread. The heat conductor can bear the conduction effect of the sidewall temperature and the tread temperature, and realize the rapid cooling of the tread during the movement. Since rubber is a poor conductor of heat, it is difficult to achieve rapid cooling by simply relying on the arrangement of pattern grooves on the tread. However, the heat conductive material layer in the heat conductor has a good heat conductive effect. By utilizing its excellent heat conductive performance, the temperature of the tread can be quickly transferred, and the tread can be quickly cooled, which is conducive to ensuring driving safety.
[0017] The utility model provides a heat dissipation type new energy vehicle tire, which transfers the heat of the tread to the sidewall by arranging heat dissipation grooves and heat conductors, thereby effectively and quickly reducing the tread temperature. The effective control of the tread temperature can reduce the risk of tire blowout due to overheating and improve driving safety. The effective reduction of the tread temperature helps to maintain the optimal elasticity of the rubber, thereby providing good grip on wet or dry roads. The effective reduction of the tread temperature can reduce material aging caused by overheating and increase the service life of the tire, providing a new idea for reducing the temperature of the tread.

DETAILED DESCRIPTION

Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field without creative work based on the embodiments in the embodiments of the present application are within the scope of protection requested by the present application.
[0025] like Figure 1-4As shown, a heat dissipation type new energy vehicle tire includes a tire body, the tire body includes a tread 1, a shoulder 2 and a sidewall 3, the tire body includes the tread 1, the shoulder 2, the sidewall 3 and the bead 9 from the outside to the inside, the tread 1 is composed of a silicone rubber protective layer 6, a cap layer 7, a steel belt layer 8, fluorosilicone rubber and fluoroether rubber from the outside to the inside, and the outer layer of the shoulder 2 and the sidewall 3 is also composed of a silicone rubber protective layer 6; a heat dissipation groove 4 is arranged on the surface layer (i.e., the silicone rubber protective layer 6) of the tread 1, the shoulder 2 and the sidewall 3, a heat conductor 5 is arranged in the heat dissipation groove 4, the heat conductor 5 is fixedly connected to the heat dissipation groove 4, the heat conductor 5 includes a heat conductive material layer 5-1 and a rubber material coating layer 5-2, the heat conductive material layer 5-1 contacts the bottom of the heat dissipation groove 4, and the rubber coating layer 5-2 is fixedly connected to the heat dissipation groove 4.
[0026] In another embodiment, at least four heat dissipation grooves 4 are provided, and the heat dissipation grooves 4 are evenly arranged on the tire body. The outermost layer of the rubber material coating layer 5-2 is an arc-shaped convex surface, which is beneficial to expand the surface area and is beneficial to heat dissipation. The specific number of heat dissipation grooves 4 can be adjusted according to actual conditions.
[0027] In another embodiment, the heat conductive material layer 5-1 is made of graphene fiber material, specifically graphene fiber bundles, graphene fiber fabrics, or composite fiber bundles of graphene fiber and other fibers (cotton fiber, polyurethane, polyester fiber or modal, etc.) or fabrics thereof. Graphene fiber has very excellent thermal conductivity. The graphene fiber material is arranged in the heat dissipation groove 4, which can quickly transfer the heat generated by the tread 1 to the sidewall 3, effectively reducing the temperature of the silicone rubber protective layer 6 on the tread 1.
[0028] In another embodiment, the heat conductive material layer 5-1 disposed on the tread 1 and the shoulder 2 has no contact with the outside air. Figure 5 As shown, a heat dissipation hole 11 is arranged on the rubber material coating layer 5-2 in the heat conductor 5 arranged at the sidewall 3, and the heat conductive material layer 5-1 arranged at the sidewall 3 is in contact with the outside air through the heat dissipation hole 11. The heat dissipation capacity of the sidewall 3 can be improved through the heat dissipation hole 11. At the same time, the heat conductive material layer 5-1 can dissipate the heat into the air through the heat dissipation hole 11, which is more conducive to the heat dissipation of the sidewall 3.
[0029] In another embodiment, the distance between the outermost layer of the heat conductor 5 and the center of the tire body is smaller than the distance between the outermost layer of the tread 1 and the center of the tire body, that is, the heat conductor 5 will not protrude from the outermost layer of the tread 1 or be flush with it, and the distance between the outermost layer of the heat conductor 5 and the center of the tire body is smaller than the distance between the outermost layer of the shoulder 2 and the center of the tire body, that is, the heat conductor 5 will not protrude from the outermost layer of the shoulder 2 or be flush with it.
[0030] In another embodiment, the distance between the outermost layer of the heat conductor 5 and the center of the tire body is equal to the distance between the outermost layer of the tread 1 and the center of the tire body, that is, the outermost layer of the heat conductor 5 is flush with the outermost layer of the tread 1, and the distance between the outermost layer of the heat conductor 5 and the center of the tire body is equal to the distance between the outermost layer of the shoulder 2 and the center of the tire body, that is, the outermost layer of the heat conductor 5 is flush with the outermost layer of the shoulder 2.
[0031] In another embodiment, the outermost layer of the heat conductor 5 is recessed in the outermost layer of the sidewall 3, which allows the tire to have more contact area with the outside world, which is beneficial for heat dissipation and drainage.
[0032] In another embodiment, the outermost layer of the heat conductor 5 protrudes from the outermost layer of the sidewall 3, or the heat conductor 5 is flush with the outermost layer of the sidewall 3. The outermost layer of the heat conductor 5 protrudes from the outermost layer of the sidewall 3, which can form a bulge, and can also increase the contact surface and improve the heat dissipation capacity. When the appropriate number of heat conductors 5 is set, two heat conductors 5 will form a large groove on the sidewall 3, which is conducive to placing the tire binding chain in the large groove on snowy days, helping to stabilize the chain and improve the safety of driving on snowy days.
[0033] In another embodiment, the heat conductor 5 and the tire body can be connected by first placing the heat conductive material layer 5-1 at a specific position and then forming the rubber material coating layer 5-2 and the tire body as one piece, or by first placing the heat conductive material layer 5-1 at the bottom of the heat dissipation groove 4 and then gluing the two sides of the rubber material coating layer to the heat dissipation groove 4 (i.e., the silicone rubber protective layer 6). Other existing technical means can also be used to set the heat conductor 5 in the heat dissipation groove 4.
[0034] Although there are many ways to improve the heat dissipation capacity of a tire, most of them are to directly dissipate heat for the tread 1, such as opening tread grooves. Since the surface layer of the tread 1 is made of rubber, it is not easy to dissipate heat. The utility model connects the tread 1 and the sidewall 3 through a heat conductor 5 to achieve a method of quickly transferring heat. A transfer heat dissipation method is adopted in which the heat of the tread 1 is first transferred to the sidewall 3 and then dissipated. Compared with the direct heat dissipation method, the transfer heat dissipation method can reduce the temperature of the tread 1 more quickly. The utility model can also be combined with other heat dissipation methods in the prior art to directly dissipate heat for the tread 1, which is equivalent to the application using a transfer heat dissipation method combined with a direct heat dissipation method to dissipate heat for the tire. The utility model provides a heat dissipation type new energy vehicle tire. By setting heat dissipation grooves 4 and heat dissipation holes 11, the area in contact between the tire and the outside air can be increased, thereby improving the heat dissipation efficiency, which helps to reduce the temperature accumulation of the tire when it is running at high speed or working for a long time, and prolong the service life of the tire; a heat conductor 5 is set in the groove, and the temperature of the tread 1 can be quickly transferred to the sidewall 3, which is conducive to quickly cooling the tread 1. The heat conductor 5 can bear the conduction effect of the temperature of the sidewall 3 and the temperature of the tread 1, so as to achieve rapid cooling of the tread 1 during movement. Since rubber is a poor conductor of heat, it is difficult to achieve rapid cooling by simply setting pattern grooves on the tread 1. However, the heat conductive material layer 5-1 in the heat conductor 5 has a good heat conductive effect. By utilizing its excellent heat conductive performance, the temperature of the tread 1 can be quickly transferred, so as to achieve rapid cooling of the tread 1, which is conducive to ensuring driving safety.
[0035] The utility model provides a heat dissipation type new energy vehicle tire, which transfers the heat of the tread 1 to the sidewall 3 by arranging the heat dissipation groove 4 and the heat conductor 5, thereby effectively and quickly reducing the temperature of the tread 1. The effective control of the temperature of the tread 1 can reduce the risk of tire blowout due to overheating and improve driving safety. The effective reduction of the temperature of the tread 1 helps to maintain the optimal elasticity of the rubber, thereby providing good grip on wet or dry roads. The effective reduction of the temperature of the tread 1 can reduce material aging caused by overheating, improve the service life of the tire, and provide a new idea for reducing the temperature of the tread 1.
