Anti-explosion tire

Abstract

The invention relates to an explosion-proof tire. The tire comprises a hub assembly, an inner tire and an outer tire, the hub assembly includes a rim, wherein the rim is provided with a groove; a second hub protruding out of the bottom surface of the groove is arranged in the groove of the rim; the inner tire is sleeved on the second hub; the outer tire is sleeved on the rim, the inner tire is completely coated; the inner tire is a solid inner tire, the inner tire is provided with an inner tire groove, a plurality of solid clamping protrusions protruding out of the inner side surface of the outer tire are arranged on the inner side of the outer tire and correspond to the inner tire grooves. The anti-explosion tire is used as a common vacuum tire at ordinary times, when the tire bursts, the solid clamping protrusions on the inner side of the outer tire is instantly pressed into the inner tire groove of the inner tire; the protrusions on the side walls of the inner tire grooves are pressed into the clamping grooves of the solid clamping protrusions, at the moment, the inner tire and the solid clamping protrusions of the outer tire are combined to form a solid tire for supporting theouter tire, the outer tire can be replaced immediately under the conditions that the outer tire leaks air rapidly, especially bursts suddenly, supporting and other effects are achieved, and a vehiclecannot incline seriously and is close to a normal state.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to a run-flat tire. Background technique [0002] Tires are ground-rolling circular elastic rubber products assembled on various vehicles or machinery. They are usually installed on metal hubs, which can support the body, buffer external impact, realize contact with the road surface and ensure the driving of the vehicle. performance. [0003] At present, tires are divided into two types: pneumatic tires and non-pneumatic tires. Vehicles with pneumatic tires can travel more kilometers, save fuel, have less tire noise, and have better ride comfort. However, the heat dissipation efficiency of pneumatic tires is low during vehicle driving. When people drive long distances, the temperature of the tires will be greatly increased. When the inflated tires reach a certain temperature, there may be a tire blowout. Car crash fatal traffic accident. Contents of the invention [0004] Aiming at th...
