Adjustable pressure maintenance ring

Abstract

The invention discloses an adjustable pressure maintenance ring which comprises a hub mechanism, a pressure adjustment mechanism and an adjustment mechanism; in the hub mechanism, a rim and an air tap with tire pressure and temperature are arranged in a hub; an air storage barrel is arranged in the rim; an adjustment hole is formed in the bottom of the air storage barrel; an adjustment cavity is formed in the lower part of the air storage barrel; the pressure adjustment mechanism is arranged in the air storage barrel; a limiting piece is arranged on the air storage barrel; an air tap cover is arranged below the limiting piece and is internally provided with the air tap; an air bag is arranged below the air tap; the adjustment mechanism is provided with an adjustment device below the air bag; and the adjustment device is arranged in the adjustment hole. According to the adjustable pressure maintenance ring, with adoption of the air storage barrel arranged in the hub as a protective cavity of the air bag, air bag control and protection are infinitely expanded; a customized constant pressure air bag is adopted to store and release overpressure air in a tire; the adjustment device is adopted to control the capacity of the air storage barrel so as to enable the tire pressure to meet the requirements on various road conditions, comfort degree, safety coefficient, oil consumption and the like, so that the manufacturing cost is low, and the popularity is high.

Description

technical field [0001] The invention relates to the field of automobile manufacturing, in particular to an adjustable retaining ring. Background technique [0002] In order to prevent the tire pressure from rising due to long-term, high-speed, and high-temperature driving, and to make the vehicle more fuel-efficient, Chinese patent 201511034450.3 discloses a technology that uses elastomers as elastic sealing materials to automatically adjust tire pressure. But the weather adaptability of this prior art is not strong, and the performance maintenance period is short; and it adopts the temperature deformation function of the bimetal to adjust the volume of the inner tube to achieve the purpose of automatic pressure regulation, and the cost of the bimetal material is high. Contents of the invention [0003] Another object of the present invention is to provide an adjustable pressure retaining ring to improve the safety performance of the tire and reduce the cost. [0004] Acc...

[0002] In order to prevent the vehicle from running for a long time, at high speed, and in high temperature weather, the tire pressure rises and cause a tire burst, and to make the vehicle more fuel-efficient, Chinese patent 201511034450.3 discloses a technology that uses elastomers as elastic sealing materials to automatically adjust tire pressure. However, the climate adaptability of this prior art is not strong, and the performance maintenance period is short; moreover, it uses the temperature deformation function of the bimetal to adjust the volume of the inner tube to achieve the purpose of automatic pressure regulation, and the cost of the bimetal material is high
