Example Embodiment

[0067] The following is a detailed description with the accompanying drawings and examples:

[0068] 1. Overall

[0069] Such as figure 1 , 2 , This assembly includes rotary joint sub-assembly 100, mounting bracket sub-assembly 200 and valve and tracheal sub-assembly 300;

[0070] Its location and connection relationship are:

[0071] The rotary joint sub-assembly 100 is connected with the mounting bracket sub-assembly 200, and the valve air pipe sub-assembly 300 is connected with the mounting bracket sub-assembly 200;

[0072] The inner cavity of the rotary joint sub-assembly 100 and the valve air pipe sub-assembly 300 form a one-way air chamber.

[0073] The rotating part is connected with the rotating cavity, and the stationary part is connected with the static cavity. There is a complete gas channel between the two parts. The skeleton oil seal completes the gas path seal between the rotating part and the stationary part to prevent gas leakage.

Abstract

The invention discloses an automatic-inflation wheel side framework-type rotating joint assembly with an air pipe for a trailer tire, and relates to a vehicle tire inflation technology. The assembly is characterized in that a rotating joint sub-assembly (100) is connected with a mounting bracket sub-assembly (200), and a tire valve air pipe sub-assembly (300) is connected with the mounting bracket sub-assembly (200); a one-way ventilating air chamber is formed by the rotating joint sub-assembly (100) and an inner cavity of the tire valve air pipe sub-assembly (300); a rotating part is connected with a rotating cavity, a stationary part is connected with a stationary cavity, and an integrated air channel is arranged between the rotating part and the stationary part; and a framework oil seal completes the air channel seal of the rotating part and the stationary part, air leakage is avoided. The automatic-inflation wheel side framework-type rotating joint assembly has the advantages of simple structure and convenient operation, installation and maintenance for a driver. Air inflation can be completed under the condition of air pressure supply, pressure measuring can be completed by manual operation, and the air channel of a tire and the assembly ventilates in a one-way manner.

Description

technical field [0001] The invention relates to vehicle tire inflation technology, in particular to a trailer tire automatic inflation wheel frame rotary joint with air pipe assembly. Background technique [0002] With the rapid development of automobile technology, people's demand for tire pressure control is increasing day by day, and the use of special vehicles makes this demand more obvious. As a special-purpose vehicle, the control of tire pressure is not only related to tire wear and vehicle fuel consumption, but also related to driving safety. Trailer axles are generally not equipped with rotary air seals, making it difficult to refill tires while the trailer is running. [0003] The rotary joint can solve this problem very well. The rotary joint includes three parts, namely the rotating part, the sealing part and the static part. The rotating part is connected with the rotating chamber, and the static part is connected with the static chamber. There is a complete g...
