Problems solved by technology
In the existing technology, the rotary sealing ring is in a state of wear for a long time during the running of the vehicle. When the wear reaches a certain level, the sealing effect of the rotary sealing ring on the gas will decrease, resulting in air leakage and the failure of the entire inflation and deflation system; Long-term wear of the sealing ring will generate a lot of heat, and the heat itself will aggravate the aging speed of the rotating sealing ring

The invention discloses a charging and deflating device for a rotating tire, which comprises a rotating part consisting of an outer sealing plate, an inner sealing plate and a sleeve and a non-rotating part consisting of an outer cylinder barrel, an inner cylinder barrel, a rotating sealing ring and a dust ring, wherein, the outer sealing plate is installed on the sleeve and adjacent to one end of the wheel, the inner sealing plate is installed on the sleeve and far from one end of the wheel, the inner cylinder barrel is sheathed on the sleeve and positioned between the inner sealing plate and the outer sealing plate, the outer cylinder barrel is sheathed on the inner cylinder barrel and positioned between the inner sealing plate and the outer sealing plate, and rotating sealing rings are respectively installed between the inner cylinder barrel and the outer cylinder barrel and at the positions adjacent to the inner and outer sealing plates. Compared with the prior art, the rotating sealing rings are completely free from long-term abrasion and high-temperature environment, therefore, the service life is prolonged, and the reliability of the entire charging and deflating system is further enhanced; and simultaneously, the invention provides a simple realization method for the control system, therefore, the entire CTI / DS is simplified.
Description
technical field [0001] The invention relates to a device for inflation and deflation of rotating tires and a control system thereof, in particular to a rotating sealed air chamber and a control system in a central tire inflation and deflation system. Background technique [0002] The tire central inflation and deflation system (CTI / DS) of off-road vehicles is mainly composed of air source, steering control device, rotary sealing device, wheel valve and connecting air circuit, etc. It is used to adjust the air pressure of the tire to adapt to different road conditions. To improve the maneuverability of the vehicle. The rotary sealing device is one of the key components of the system. It includes two parts, the non-rotating part and the rotating part. The two parts are connected by a rotating sealing ring. The compressed gas from the gas source is realized by the dynamic sealing effect of the rotating sealing ring. Transmit to the rotating tire air chamber, or transmit the ga...
