Multifunctional front cross beam assembly with gas storage function

The invention discloses a multifunctional front cross beam assembly with a gas storage function, and belongs to the technical field of heavy truck front cross beams. The multifunctional front cross beam assembly with the gas storage function comprises a front cross beam assembly and cab air bag suspensions which are arranged on the two sides of the front cross beam assembly and are used for supporting a cab; an air storage cavity is formed in the front cross beam assembly; the air storage cavity is communicated with an air inlet valve of an automobile through an air inlet pipe; the air storagecavity is communicated with the cab air bag suspensions on the two sides one by one through air outlet pipes. The multifunctional front cross beam assembly with the gas storage function is light in weight and high in structural strength, the space arrangement occupancy rate of a chassis is reduced due to the gas storage function; multifunctional integration such as bumpers, trailer hooks and gasstorage cylinders can be a
