The invention discloses a three-axle carriage air suspension air channel control system comprising an air storage cylinder which is used for storing high pressure air and is arranged on a carriage chassis; an automatic load sensing valve which is communicated with the air storage cylinder and arranged on the carriage chassis and is communicated with multiple bearing air bags arranged on a servo axle air suspension; a transverse pendulum assembly of which one end is fixedly connected with the camshaft of the automatic load sensing valve and drives the camshaft to rotate around the axis, wherein output air pressure of the automatic load sensing valve changes along with change of the swing angle of the transverse pendulum assembly; and a vertical pendulum assembly of which one end is hinged with the transverse pendulum assembly and the other end is fixedly connected with a driving axle left spring suspension. Advantages of the three-axle carriage air suspension air channel control system are that the structure is simple, and servo axle load can be limited so that the service life of the servo axle is enhanced and servo axle tire wearing is also reduced.
