Detachable multi-airbag explosion-proof tire

Abstract

The invention discloses a multi-airbag anti-explosion tire which can be easily dismantled, which comprises a wheel hub, a fan-shaped inner tube and an outer tire. There is also an annular inner tube between the hub and the fan-shaped inner tube. The annular inner tube is in contact with all the fan-shaped inner tubes and a vent valve is set on the contact surface to communicate with the space in the annular inner tube and the fan-shaped inner tube. An air nozzle is set on the annular inner tube, and the outer tire also wraps the annular inner tube. . A shaft hole is arranged in the center of the hub, a transmission groove is arranged on one end surface of the central part of the hub, and a transmission assembly is arranged in the shaft hole. The transmission assembly includes a hub bearing and a rotating block. The rotating block is embedded in the transmission groove, and the pressure plate and the wheel hub are threaded to press the rotating block in the transmission groove. The double elastic support structure of the valve ball in the ventilation valve can block the air passage of a fan-shaped tire in time after the rupture of a fan-shaped tire.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to an easily disassembled multi-airbag explosion-proof tire. Background technique [0002] The tire is a very important part of the car, which supports the car body on the ground. Except for maintenance, the tires of the car are in contact with the ground. [0003] The tire is generally composed of a tire and an inner tube. The outer tire is usually a thick rubber layer with a non-slip pattern on the surface. The inner tube is located in the outer tire, and the inner tube is filled with compressed air to stretch the outer tire to play a supporting role. [0004] In the prior art, there is only one inner tube. When the car is running, once sundries such as nails are stuck into the outer tire or the inner tube is ruptured due to other factors, the whole tire will lose its function, and the car is very easy to lose control, causing danger, especially in high-speed driving. At the same time, ...

Problems solved by technology

[0004] In the prior art, there is only one inner tube. When the car is running, once sundries such as nails are stuck into the outer tire or the inner tube is ruptured due to other factors, the whole tire will lose its function, and the car is very easy to lose control, causing danger, especially in high-speed driving. At this time, the blowout of the entire tire can also cause a shock wave, and the car is even more out of control.

[0005] Existing tires are generally fixed to the wheel axle by multiple bolts and screws, and it is not easy to disassemble. All bolts and screws need to be removed every time they are disassembled, and the efficiency of disassembly and assembly is low.
