Embodiment Construction

[0021] A new type of run-flat tire, such as figure 1 As shown, it is mainly composed of hub 1, carcass 2, filler 3, gas 4 and inflation conduit 5 and other components.

[0022] The filler is wrapped by the carcass and fits closely with the hub, and the filler is filled with gas; the inflation conduit is set inside the hub.

[0023] Among them, the inner filler of the tire is a belt-shaped ring composed of light, high-strength, and high-elastic polymer composite materials similar to honeycomb foam; the filler has been optimized and has high strength and high elasticity. When it is damaged due to air leakage or blasting, it can play a strong supporting role to ensure that the tire does not produce large deformation in the vertical and lateral directions, maintain good rolling performance, and ensure that the vehicle / aircraft can roll normally.

[0024] Further, each bubble body in the filler can communicate with each other, so that the gas can reach each bubble body.

[0025] ...

Abstract

The invention belongs to the field of tire development, and discloses a novel run-flat tire which is mainly composed of a hub, a rubber tire body, filler, gas, uniformly distributed inflation conduitsand the like. The respective advantages of the traditional pneumatic tire and the non-pneumatic tire are combined, the mode that light, high-strength and high-elasticity special filler is designed and placed in the traditional pneumatic tire is adopted; by means of the excellent performance of the traditional pneumatic tire in the aspects of vibration reduction, buffering, comfort and the like and the strong supporting safety such as high strength, high elasticity, light weight and the like of internal filler, the requirements for vibration reduction, buffering, comfort, safety during air leakage / tire burst and the like of the tire when a vehicle / airplane moves on the ground are met. And the ground motion safety and comfort of vehicles / airplanes are improved.

Description

technical field [0001] The invention belongs to the field of tire development, in particular to a run-flat tire. Background technique [0002] Tires, as vehicles, aircraft, etc., are essential components for support, vibration reduction, cushioning, etc. when moving on the ground, and have an extremely important impact on their ground motion performance. Its main functions: carrying the weight of the vehicle / aircraft; buffering the vibration and impact of the vehicle / aircraft from the ground; assisting the movement of the vehicle / aircraft on the ground; transmitting braking force to the runway, providing lateral force for steering, etc. Traditional pneumatic tires have the advantages of good load bearing, vibration damping, buffering, and low rolling resistance, but because they are filled with high-pressure gas in the sealed rubber cavity to achieve load bearing, vibration damping, buffering, and other functions. Therefore, once air leakage or explosion occurs, especially ...
