Problems solved by technology

This invention adopts three air chambers that are not connected to each other. Although it can achieve the purpose of vehicle tire explosion protection, it is easy to cause the air pressure between the air chambers of the tire to be unequal during the tire inflation process, thereby reducing the smoothness of vehicle driving. Sexuality, and even increase the chance of vehicle blowout

Abstract

The invention relates to a multiple-air chamber anti-explosion tyre with high-performance one-way valves and belongs to the technical field of tyres. The tyre comprises a tyre body and a plurality of cavities, wherein the cavities comprise air inflation cavities and a plurality of air storage cavities; a first separation layer is arranged between the air inflation cavity and the air storage cavities; the one-way valve is arranged on the first separation layer; a second separation layer is arranged between two adjacent air storage cavities; the one-way valve comprises a valve body, a piston, a pressing cap and a seal layer between the valve body and the pressing cap; the piston and the seal layer of the one-way valve are made of a composite material; and the composite material comprises the following components: 8-20% of polytetrafluoroethylene powder, 0.5-10% of surface modified carbon fiber, 0.5-10% of modified nanometer CaCO3, 0.5-10% of nanometer Si2N4 and the balance of polyetheretherketone powder. The tyre is simple in structure, air pressures of the air cavities are equal, the one-way valves are made of the composite material, the probability of tyre burst of a vehicle is reduced, and the service life of the tyre is prolonged.

Description

technical field [0001] The invention belongs to the technical field of tires and relates to a multi-chamber explosion-proof tire with a high-performance check valve. Background technique [0002] Vehicles are increasingly becoming an important tool for people's life and work. More and more developed highways and high-tech vehicles make the speed of vehicles faster and faster, which brings convenience to people and also brings huge benefits. Potential safety hazards, a tire blowout at high speed will cause an instant deflection. If the consequences of a tire blowout are light, the vehicle will lose its normal driving state, the steering wheel will lose control, and the vehicle will drive sideways. In severe cases, the vehicle will completely lose control and flick, causing major traffic accident. [0003] The multi-chamber tire of the prior art, such as the Chinese invention patent multi-chamber explosion-proof tire of the notification number CN2803775, comprises the first a...
