The invention discloses a bearing shaft axle housing assembly of an I-shaped beam section. The bearing shaft axle housing assembly mainly comprises an axle housing body assembly and a shaft head, theaxle housing body assembly comprises an upper half housing, a vertical plate and a lower half housing, and the upper and lower end faces of the vertical plate fit the central planes of the upper halfhousing and lower half housing respectively by means of welding; semicircular structures at the two ends of the upper half housing and lower half housing are welded to each other to form an annular end face, and the annular end face is aligned with an annular end face of the shaft head by means of welding; the middle of the vertical plate is of a rectangular flat plate structure, the two ends of the flat plate structure are of arc-shaped closed structures, and the arc-shaped closed structures are welded to arc-shaped faces of the upper half housing and lower half housing. Through the axle housing assembly with variable cross sections and unequal wall thicknesses, not only can uniform distribution of stress be realized, the weight can be reduced, but also the load of the axle housing assembly can be effectively increased.
Description
technical field [0001] The invention belongs to the field of automobile driving axles, and in particular relates to a load-bearing axle-axle assembly with an I-beam section. Background technique [0002] The axle housing assembly of the bearing shaft of the domestic automobile axle mostly adopts a square cross-section structure. The reaction rod bracket usually uses a C-shaped groove to straddle the square cross-section beam, which will also increase the overall weight of the axle housing assembly carrying the axle. Contents of the invention [0003] The technical problem to be solved by the present invention is to aim at the deficiencies in the prior art, and to provide a load-bearing axle and axle housing assembly with an I-beam section, a hollow upper reaction rod bracket, a T-shaped lower reaction rod bracket, and a The plate spring seat with C-shaped grooves has a structure with constant cross-section and unequal wall thickness, which can not only make the stress dis...
