A kind of motor vehicle tire with dust-proof mechanism

Abstract

The invention discloses a tyre with a dust prevention mechanism, for motor vehicles. The tyre comprises a tyre body, an inflation mechanism, an inflation valve mechanism and a dust prevention mechanism, wherein the tyre body comprises an inflation cavity; the inflation mechanism is arranged on the tyre body; the inflation mechanism comprises a mounting channel; the mounting channel communicates with the inflation cavity of the tyre body; the inflation valve mechanism comprises an inflation body, an inflation end and an exhausting end; the inflation end and the exhausting end are separately positioned at two ends of the inflation body; the inflation body is mounted at the mounting channel of the inflation mechanism; the exhausting end is positioned at the mounting channel; the inflation end extends out of the inflation mechanism from the mounting channel of the inflation mechanism; the dust prevention mechanism is arranged on the inflation body, positioned at the exhausting end of the inflation valve mechanism, and provided with one or more inflation channels; each inflation channel communicates with the inflation body and the mounting channel.

Description

technical field [0001] The invention relates to a vehicle tire, in particular to a motor vehicle tire with a dustproof mechanism. Background technique [0002] Tires are annular elastic rubber products applied to various vehicles, and are widely used in almost all civil vehicle machinery including motor vehicles and non-motor vehicles. Under normal circumstances, tires can form an inflated circular ring only after being inflated with gas to support the vehicle body, buffer the impact of the vehicle itself and the outside world, realize contact with the road surface and ensure the driving performance of the vehicle. [0003] The tire is equipped with an inflation nozzle. In order to ensure the safety of the tire and prevent the tire from leaking, the inflation nozzle usually adopts a push-type inflation mechanism. That is to say, when the tire is inflated and deflated, it can only be pressed Specifically, during the inflation process, when the air pump is inserted into the i...

AI Technical Summary

Problems solved by technology

[0004] During the process of inflating the tires, the small solid particles in the air pump or the small solid particles adhering to the inflation nozzle during the driving of the vehicle will cause the air pump to inflate the tire due to the strong air pressure provided by the air pump. Inflate it into the inside of the tire, on the one hand, these small solid particles will wear the tire from the inside of the tire, on the other hand, especially when the inflation is completed, these small particles will be pushed to the inflation nozzle by the air pressure inside the inner wheel The position of the inflation nozzle is squeezed from the inside of the inflation nozzle (sealing mechanism). Once this happens, the inflation nozzle cannot be completely sealed, so that the gas in the tire will leak. If it goes on for a long time, it will not only It will have a bad effect on the tire itself, and it will also pose a potential threat to the safe driving of the vehicle
