Integrally-cast crossbeam with air storage function of air suspension frame

Abstract

The invention relates to an integrally-cast crossbeam with an air storage function of an air suspension frame. The crossbeam comprises a crossbeam main body and a pair of sealing end covers arranged at the two ends of the direction of the long axis of a crossbeam pipe body, wherein the crossbeam main body is formed by integrally casting the crossbeam pipe body and a pair of crossbeam connectors which are symmetrically arranged at the two ends of the crossbeam pipe body; meanwhile, a V-shaped seat pushing group is further integrally cast and formed on the outer wall of the crossbeam pipe body,and an air inlet and an air outlet are formed in the crossbeam pipe body; a reinforced convex rib group is further arranged on the inner wall of the crossbeam pipe body; and a seal ring set attached to the inner wall of the crossbeam pipe body is further mounted to the outer walls of one sections of the sealing end covers, wherein one sections of the sealing end covers extend into a cavity of thecrossbeam pipe body. The integrally-cast crossbeam has the advantages that the crossbeam is formed by integrally cast, on the basis of air supply storage, the sealing performance of the crossbeam canbe improved, the structural strength of the crossbeam is ensured, and meanwhile, manufacturing is more convenient.

Description

technical field [0001] The invention relates to the field of automobile manufacturing, in particular to an integrally cast air suspension beam with an air storage function. Background technique [0002] At present, with the development of truck hydraulic and pneumatic control system technology, the amount of compressed air used by the whole vehicle has increased significantly. In order to meet the requirements of increasing air consumption of the vehicle, there are two main solutions: 1. Increase the pressure of the compressed air system; 2. Increase the capacity or quantity of the air storage tank. To increase the pressure of the compressed air system, the relevant supporting components of the air path are required to meet its performance, which is more complicated to realize. Therefore, increasing the capacity and number of gas storage tanks is an easy measure to implement. However, the increase in the number of air storage tanks will lead to the following problems: incr...

Problems solved by technology

However, the increase in the number of air storage tanks will lead to the following problems: increase the weight and cost of the braking system; in short-wheelbase models or models with many system configuration parts, such as tractors, the air storage tanks are arranged in a narrow space or difficult to arrange.

However, the beam tube body is a split structure, which is welded by a tubular body and two symmetrical beam connectors, and the beam tube body needs to replace the gas storage tank, so the sealing performance is very high. For The welding quality requirements are relatively strict, and the precision requirements between the parts are also relatively high, and the manufacturing and assembly are relatively troublesome; in addition, for the outer body of the beam, it is used to connect the left and right longitudinal beams of the frame, so If the wall thickness is too thin, the structural strength of the beam tube body cannot be guaranteed, thus affecting the overall connection. However, the beam tube body needs to be used as a gas storage tank. If the wall thickness is too thick, the stored gas will also be damaged. correspondingly less
