Problems solved by technology

However, due to the difference in air pressure between the four tires of a general vehicle, it is difficult for the existing tire central inflation and deflation system to independently supply or deflate the inner and outer tires of each tire, which affects the safety of the vehicle during driving.

Abstract

The present invention relates to the field of tire automatic inflation systems, and discloses a dual-channel rotation sealing apparatus assembly, which comprises a tire edge bracket, a dual-channel rotation shaft arranged on the tire edge bracket, and a rotation joint body arranged on the dual-channel rotation shaft, wherein the rotation joint body is provided with two gas inlet channels and a first gas outlet channel, the tire edge bracket is provided with two second gas outlet channels, the middle portion of the tire edge bracket is provided with a concave groove, a bearing is sleeved on the top end of the dual-channel rotation shaft, a bearing cover is sleeved on the middle portion of the dual-channel rotation shaft, the top end of the dual-channel rotation shaft is pressed into the first gas outlet channel of the rotation joint body, the dual-channel rotation shaft is locked on the rotation joint body by the bearing cover through a hexagon socket head cap screw and an elastic pad, and the terminal end of the dual-channel rotation shaft is screwed into the concave groove. According to the present invention, the dual-channel rotation sealing apparatus assembly can control the independent gas supply or deflation of the inner tire or outer tire of the vehicle, wherein the control of the vehicle gas inflation-deflation system on other tires cannot be affected when there is a problem in one of the inner tires or outer tires of the vehicle so as to improve the safety of the vehicle during the driving.

Description

technical field [0001] The invention relates to the field of tire automatic inflation systems, in particular to a dual-channel rotary sealing device assembly. Background technique [0002] When the vehicle is running on a good road surface, in order to make the vehicle run at the highest possible speed and give full play to the maneuverability, it is required to increase the inflation pressure of the tire as much as possible to reduce the rolling resistance and the loss of tire deformation energy, but at the same time, when the vehicle When passing through complex road surfaces (such as deserts, coastal beaches, swamps, muddy ground and other soft ground and ice and snow roads), the vehicle not only needs to pass smoothly, but also needs the vehicle to maintain a certain off-road speed, which requires reducing the inflation pressure of the tires. On the one hand The tire subsidence and soil resistance are reduced. On the other hand, because the number of tire patterns embedd...
