A shock-absorbing tire and its manufacturing process

Abstract

The invention discloses a shock-absorbing tire and a manufacturing process thereof, comprising a casing and a ring-shaped shock-absorbing core. The shock-absorbing core is located in the casing and is wrapped by the casing. The overall heating or local heating at the splicing part makes the upper and lower casings fused together by heat and then cooled and solidified to form. The upper and lower casings are both prepared by rubber vulcanization process. There is an upper half cavity, and the lower half casing is provided with a lower half cavity. When the upper half casing and the lower half casing are spliced ​​together, the upper half cavity and the lower half cavity are also spliced ​​together to form an annular inner cavity for accommodating the shock absorbing core, reducing the The hardness of the shock-absorbing core is smaller than that of the tire, and the melting point of the shock-absorbing core is higher than that of the tire. It has lower production cost and better anti-skid performance and anti-aging performance.

Description

technical field [0001] The invention relates to a tire, in particular to a shock-absorbing tire and a manufacturing process thereof. Background technique [0002] There are usually two types of tires used in traditional scooters or skateboards, the first is pneumatic tires, and the second is solid tires. Among them, a cavity for inflation is arranged inside the pneumatic tire, and the weight is relatively light. During the running process, the inner cavity of the pneumatic tire and the inflated body have a buffering effect, and the shock absorption effect is good. However, pneumatic tires need to be frequently inflated to ensure their normal operation, which is inconvenient to use, and when the speed of the scooter or skateboard is fast, the gas in the pneumatic tire is heated and expanded, which is easy to blow out and has low safety. There is no cavity for inflation inside the solid tire, and it does not need to be inflated. There is no tire blowout problem when the speed...

AI Technical Summary

Problems solved by technology

When the tire is molded, the shock-absorbing and noise-reducing ring is easily affected by the impact of injection molding / perfusion and deviates from its actual design position (the center of the tire). Once the deviation is large, it can only be scrapped directly. At the same time, the tire can only be used Use injection moldable materials (such as TPE) or potting materials (polyurethane)

The cost of TPE material is high, the anti-aging performance and anti-skid performance are worse than rubber materials, and the anti-skid effect of PU (polyurethane) material is not good. Deformed, need to be replaced as a whole, and the replacement cost is high
