Description

Technical Field

[0002] Tires are ground-contacting, rolling, annular elastic rubber products installed on various vehicles or machinery. They are usually installed on metal rims and can support the vehicle body, cushion external impacts, achieve contact with the road surface and ensure the vehicle's driving performance. Tires are often used under complex and harsh conditions. They are subjected to various deformations, loads, forces, and high and low temperature effects when driving. Therefore, they must have high load-bearing performance, traction performance, and cushioning performance. At the same time, they are also required to have high wear resistance and flexibility resistance, as well as low rolling resistance and heat generation. Solid tires are generally chosen for construction machinery vehicles, generally including polyurethane solid tires and polyurethane rubber composite solid tires. Solid tires have unique advantages, such as puncture resistance, tear resistance, no need for inflation, and long service life.

[0003] Among them, an ultra-load-bearing shock-absorbing engineering tire with application number "CN201320670825.5" is designed to be a traditional solid tire with three layers: inner, middle and outer. It makes full use of the super-hard, wear-resistant and scratch-resistant properties of the outer layer. The internal matrix is ​​polyurethane material, and the inner core material is T-shaped sponge filler, which can maximize the overall elasticity of the tire and form an effective shock-absorbing effect during actual use. It has shock-absorbing properties that general solid tires do not have, improves the comfort and stability of vehicle load-bearing, and can be widely used in various industrial vehicles, military vehicles, construction machinery, trailer vehicles at ports and airports, and other fields.

[0004] However, the above-mentioned type of super-load-bearing shock-absorbing engineering tire still has certain shortcomings when in use. Since no structure or component is set inside the rubber layer to improve the supporting strength, it can only rely on the rubber layer itself to provide a certain supporting strength, which cannot meet higher strength load-bearing requirements and is not convenient for providing better supporting strength.
