Hub with automatic pressure adjusting pack

Abstract

A hub with an automatic pressure adjusting pack is characterized in that a rim cavity 7 is formed in a rim of a hub body 0; the pressure adjusting pack 1 is arranged in the rim cavity 7; an air nipple 6 is arranged on the pressure adjusting pack 1 and provided with an air nipple sealing pad 4 and an air nipple cap nut 5; a tension spring 2 is arranged inside the pressure adjusting pack 1; positioning skin 3 is arranged at the two ends of the tension spring 2; a rim cavity opening 8 is formed in the outer side of the rim cavity 7; a rim cavity insertion opening 9 is arranged on the upper portion of the rim cavity opening 8; a rim cavity screw hole 10 is formed in the lower portion of the rim cavity opening 8; the rim cavity opening 8 is provided with a rim cavity cover 11; the rim cavity cover 11 is provided with a cavity cover screw 12. The pressure adjusting pack with the tension spring with the setting tension is used for buffering air when the tire pressure is increased, and the tire air pressure is relieved; when the air temperature is decreased and the tire air pressure is decreased, the pressure adjusting pack release the buffered air under the action of the tension spring and corrects unstable pressure, automatic tire pressure adjustment is ensured, tire puncturing is prevented, and a vehicle runs more safely in a more oil-saving mode.

Description

technical field [0001] The invention relates to a wheel for automobiles, in particular to a wheel hub with an automatic pressure regulating bag. Background technique [0002] For the safe driving of the vehicle and the prevention of violent tires caused by the increase of tire pressure, people use the "vehicle safety air nozzle" patent number: 200710092810.4 to replace the ordinary air nozzle to decompress and exhaust, but when the tire cools down, the tire pressure will decrease, and then drive It has to be inflated, otherwise it will increase fuel consumption, which is unscientific. Contents of the invention [0003] In view of the above problems, the present invention provides a wheel hub with an automatic pressure regulating package. [0004] According to this scheme, a wheel hub with an automatic pressure regulating bag is characterized in that: a rim chamber 7 is provided on the rim of the wheel hub 0, a pressure regulating bag 1 is arranged in the rim chamber 7, an...
