Balanced suspension beam assembly with integrated air reservoir function

Abstract

The invention discloses a balanced suspension beam assembly with an integrated air reservoir function and belongs to the technical field of motor tractor chassis structural components. The balanced suspension beam assembly comprises a beam, a beam connecting bracket, a blanking cap plate assembly, a sealing screw plug and a sealing ring, wherein the beam is a cold-drawn steel pipe; one end of the beam connecting bracket is welded at two ends of the beam so as to form a welding assembly; the other end of the beam connecting bracket is connected with a longitudinal beam web plane; the blanking cap plate assembly is respectively welded on a groove surface of the beam connecting bracket; the blanking cap plate assembly is formed by welding a plate-shaped blanking cap plate and a steel barrel into an assembly; the steel barrel is arranged at an intermediate position of the blanking cap plate; the sealing ring is arranged at a thread of the sealing screw plug in a sleeving manner and then is in threaded connection with the steel barrel on the blanking cap plate assembly, so that a closed air chamber is formed inside the beam assembly. The formed air chamber is excellent in sealing performance and can bear pressure of 13 atmospheric pressures without air leakage, and the extreme pressure resistance can bear 40 atmospheric pressures.

Description

technical field [0001] The invention belongs to the technical field of chassis structural parts of tractors, and in particular relates to a balance suspension beam assembly integrating the function of an air storage tank. Background technique [0002] At present, tractors are driven by double rear axles, balanced suspension structure, and air suspension models with double axles and 8 airbags in the rear suspension system. A set of crossbeam assembly needs to be arranged at the large bracket of the balanced suspension to ensure the overall stability of the frame. The middle and rear parts have reliable rigidity and structural strength. [0003] The structure of the traditional balance suspension beam assembly is as follows: Figure 5 As shown, the crossbeam assembly is riveted into a crossbeam assembly by 2 groove-shaped stamping part crossbeams and 4 L-shaped stamping part connecting plates. In addition, in order to install the V-shaped thrust rod in the balanced suspension...
