Problems solved by technology

[0003] If it is thickened at the nozzle hole of the gasket, it is difficult to grasp the degree of thickening. If the thickness of the nozzle hole is small, it is easy to be squeezed out from the valve groove of the rim after inflation and damaged; the thickness of the nozzle hole of the gasket is large, and local consumption The amount of glue is large, which affects the uniformity and dynamic balance of the tire
Moreover, when thickening treatment is carried out on the nozzle hole of the gasket, the gasket rubber will be squeezed into the valve groove of the rim when the tire pressure is high at the nozzle hole of the gasket. The position crack is damaged, causing the inner tube to be damaged and leak air
However, if the nylon canvas is attached to the mouth hole of the pad, it will be easily cracked and damaged after aging due to the low strength of the nylon canvas, and the production of the

Embodiment 1

[0033] as attached Figure 1-Figure 9 As shown, a tire gasket 100 includes a metal gasket 1 and a film 2, the metal gasket 1 is provided with a gasket mouth hole 11, the metal gasket 1 is sheet-shaped, and one end thereof is upturned. The metal gasket 1 is embedded in the film 2 and wrapped by the film 2. The metal gasket 1 is provided with a number of adhesive holes 13 penetrating through its thickness. The metal gasket 1 is also provided with a plurality of V-shaped Shaped positioning V-groove 12, the lower part of the positioning V-groove 12 protrudes from the lower surface of the metal gasket 1, and the upturned end of the metal gasket 1 is provided with a plurality of bending grooves 14 running through its width direction. During the production of the tire cushion belt and tire assembly in this embodiment, the left and right directions of the valve must be installed according to the direction, otherwise the tire cushion belt will not have a protective effect.

Abstract

The invention discloses a tire cushion belt and a producing method thereof, and belongs to the technical field of tire producing. The tire cushion belt comprises a metal gasket and a rubber piece; a gasket nozzle hole is formed in the metal gasket. The tire cushion belt is characterized in that the metal gasket is flake-shaped, and at least one end of the metal gasket upwarps; the metal gasket is embedded into the rubber piece and is wrapped by the rubber piece; a plurality of adhesive holes which penetrate through the thickness of the metal gasket are formed in the metal gasket; a plurality of V-shaped positioning grooves which are used for positioning are also formed in the metal gasket; the lower parts of the V-shaped positioning grooves are protruded from the lower surface of the metal gasket; a plurality of bending grooves which penetrate through a width direction of the metal gasket are formed in the upwarp end of the metal gasket. According to the tire cushion belt, the metal gasket is embedded and is wrapped in the rubber piece; the metal gasket has good rigidity and achieves a good protecting effect, so that the damage caused by extruding the tire cushion belt from an air valve nozzle slot of a wheel rim under a high atmospheric pressure is avoided; the metal gasket can effectively protect an air valve nozzle of an inner tube of a tire.

Description

technical field [0001] The invention relates to a tire cushion belt, which belongs to the technical field of tire manufacturing. The invention also relates to a method for the manufacture of the tire cushion. Background technique [0002] In the prior art, in order to protect the valve position of the tire, a tire pad is generally provided at the valve position of the inner tube of the tire. The commonly used pad is generally thickened at the mouth hole of the pad, or placed on the mouth of the pad. The hole is reinforced with nylon canvas, or an external metal gasket (commonly known as a guard plate) is installed on the mouth hole of the pad. [0003] If it is thickened at the nozzle hole of the gasket, it is difficult to grasp the degree of thickening. If the thickness of the nozzle hole is small, it is easy to be squeezed out from the valve groove of the rim after inflation and damaged; the thickness of the nozzle hole of the gasket is large, and local consumption A lar...
