Problems solved by technology

[0003] Due to the viscoelastic properties of rubber, the energy hysteresis loss during tire operation will cause rubber to generate heat, and the thicker the rubber, the higher the heat generation of the rubber, and the harder it is to conduct and dissipate the heat; the temperature of the tire increases, and the mechanical properties of the rubber decrease or even degrade failure, thereby reducing the load bearing, durability and high-speed performance of the tire, and shortening the service life of the tire, so the thickness of the tire crown wear-resistant rubber should not be too thick; on the other hand, the thickness of the crown rubber is related to the wear of the tire. The thicker the wear-resistant crown rubber, the larger the wear volume, and the longer the wear-resistant mileage of the tire. In order to improve the wear-resistant performance of the tire, the tire needs to have thicker wear-resistant crown rubber; so the wear-resistant crown rubber and low heat generation rubber are used. The double-layer tread rubber technology cannot solve the problem that the tire has both high wear resistance and heat generation

Embodiment 1

[0024] Example 1, such as figure 1 As shown, the present invention comprises a crown body 1, a tread, and a belt layer 2. The tread can be made of one or more of natural rubber, synthetic rubber, and polyurethane rubber, and is vulcanized by adding rubber fillers and chemical functional additives after mixing. The Shore hardness of the tread is preferably 70HA , which has the advantages of high resilience, tear resistance, and pinning resistance. The tread includes a tire top surface 3 and a tire side surface 4. The tire top surface 3 is provided with pattern grooves 5, and a number of heat dissipation holes are provided in the crown body 1. One or more of 5 are connected, and the heat dissipation holes are located above the belt layer 2. In this embodiment, the heat dissipation holes include a plurality of transverse heat dissipation holes 6, and the transverse heat dissipation holes 6 are arranged along the axial direction, and the included angle between the central axis o...

Embodiment 2

[0025] Example 2, such as figure 2 As shown, the difference between this embodiment and Embodiment 1 is that the crown body 1 is also provided with a plurality of transverse heat dissipation holes 6 in the axial direction between two adjacent pattern grooves 5, and all the transverse heat dissipation holes 6 The radial distances from the central axis of the tire are equal, so that all the transverse cooling holes 6 communicate in circular arcs. The remaining parts are the same as in Embodiment 1 and will not be repeated here.

Embodiment 3

[0026] Example 3, such as image 3 As shown, the difference between this embodiment and embodiment 2 lies in that the radial distance between the transverse cooling holes 6 located between the two pattern grooves 5 and the central axis of the tire is relatively large. The rest are the same as in Embodiment 2, and will not be repeated here.

Description

Technical field: [0001] The invention relates to the technical field of tires, in particular to a tire crown structure with heat dissipation function. Background technique: [0002] In traditional tire technology, in order to reduce the heat generated when the tire is running, a double-layer tread structure is usually used on the tire tread rubber. Thermal rubber, thereby reducing the heat generation of the tire, improving the load bearing, durability and high-speed performance of the tire, and prolonging the service life of the tire. [0003] Due to the viscoelastic properties of rubber, the energy hysteresis loss during tire operation will cause rubber to generate heat, and the thicker the rubber, the higher the heat generation of the rubber, and the harder it is to conduct and dissipate the heat; the temperature of the tire increases, and the mechanical properties of the rubber decrease or even degrade failure, thereby reducing the load bearing, durability and high-speed...
