High-strength inflation-free solid tire and production method thereof

Abstract

The invention relates to a high-strength inflation-free solid tire and a production method of the high-strength inflation-free solid tire. The high-strength inflation-free solid tire comprises an annular tire body which is integrally and sequentially formed by an anti-disengagement layer, a buffer layer and an anti-skid layer from the inner ring to the outer ring. Axial damping blind holes are formed in the portions, on the two side portions of the buffer layer, of the annular tire body at intervals in the annular direction of the annular tire body. The two side portions of the anti-skid layer are provided with annular grooves correspondingly, and the annular grooves are used for being in embedment fit with rims of steel rings. The inner side face of the anti-skid layer is provided with annular locating grooves matched with annular locating protrusions arranged on the rims of the steel rings. The production method of the tire comprises the steps that preheating of a rubber injection mold is completed; rubber materials are poured into the rubber injection mold; the mold is opened; the formed high-strength inflation-free solid tire attached to a movable mold core plate is manually detached from the movable mold core plate; and waste of a runner is cut off through a cutter. The high-strength inflation-free solid tire is simple in structure, good in damping effect and easy and convenient to produce.

Description

technical field [0001] The invention relates to a high-strength air-free solid tire and a production method thereof. Background technique [0002] Most of the existing character-forming tires are air-inflated, and the air-inflated tires are easy to be injured by sharp objects because they are hollow. There are also non-inflatable tires on the market, but the non-inflatable tires on the market are usually made of inner and outer cladding or solid structures, and this kind of non-inflatable tires are made of plastic materials, which have poor skid resistance and wear resistance. The friction force, the contact area between the tire and the ground must be increased, resulting in high rolling resistance; and because it is made of plastic material, it has no elasticity, and it will jump when it is hard to bump, and the shock absorption effect is poor, and it is easy to be affected by different environments and aging; The temperature difference is small, the high temperature is e...

[0002] Most of the existing letter-forming tires are inflatable, and the inflatable tires are easy to be injured by sharp objects because they are hollow.

There are also non-inflatable tires on the market, but the non-inflatable tires on the market are usually made of inner and outer cladding or solid structures, and this kind of non-inflatable tires are made of plastic materials, which have poor skid resistance and wear resistance. The friction force, the contact area between the tire and the ground must be increased, resulting in high rolling resistance; and because it is made of plastic material, it has no elasticity, and it will jump when it is hard to bump, and the shock absorption effect is poor, and it is easy to be affected by different environments and aging; Small temperature difference, high temperature is easy to soften, low temperature is easy to harden
