Description

Automobile inner tube

Technical Field

The utility model relates to an automobile tire, in particular to automobile inner tube is an automobile inner tube.

Background

Tires are indispensable parts of automobiles. The automobile tires comprise two types, namely ordinary tires and vacuum tires. The common tire comprises an inner tube and an outer tube, wherein the valve of the common tire is arranged on the inner tube, and after the inner tube of the common tire is pierced by foreign matters, the space between the inner tube and the outer tube is filled with air rapidly, so that the tire can be shrunken immediately or even can be punctured instantly. The vacuum tire is free of an inner tube, the inflating valve 2 of the vacuum tire is directly fixed on the rim 4, a rubber sealing ring is used for sealing between the rim 4 and the inflating valve 2, the rubber sealing ring is composed of a supporting sealing seat 6 at the bottom and a lip-shaped sealing ring 7 on the supporting sealing seat 6, and the supporting sealing seat 6 and the lip-shaped sealing ring 7 are of an integral structure formed by vulcanization. When the rubber sealing ring is used, the rubber sealing ring is sleeved on the inflating valve 2, the supporting sealing seat 6 of the rubber sealing ring is arranged between the limiting end 5 of the inflating valve 2 and the rim 4, the lip-shaped sealing ring 7 is filled in a gap between the rim 4 and the inflating valve 2 to seal the inflating valve 2 and the rim 4, and a closed space is formed between the rim 4 and the outer tire, as shown in fig. 1-2. The vacuum tire is slowly deflated after being punctured and can still be kept to be driven to a repair point for repair. Therefore, most automobiles, especially most passenger cars, employ vacuum tires.

Although the vacuum tire has many advantages compared with the common tire, the automobile tire with the inner tube is necessary in the occasions that the inner tube and the outer tube need to bear pressure together, such as off-road vehicles, trucks and the like, which have special requirements on the tire pressure. Therefore, it is necessary to provide an inner tube for a vehicle, which has both advantages of a general tire and a vacuum tire.
