Principle of the present invention is: show that beam front axle housing assy is difficult to meet the strength at repeated alternation number of times of 13T passenger-cargo dual-purpose driving axle housing assembly national standard requirement through many experiments, and the weak part of this axle case assy is mainly close proximity to the axle housing girth joint position of spring block, namely the vertical bending coefficient of WV-dangerous section place (near spring block) axle housing and girth joint position quality have direct relation and in direct ratio, when girth joint positional distance spring block is far away, namely the vertical bending coefficient of WV-dangerous section place (near spring block) axle housing diminishes, the bearing capacity of axle case assy is stronger.
The technical solution of the utility model is: comprise axle housing, two braking flanges and two axle tubes, left and right two upper adapter plate spring abutments respectively of axle housing, described two braking flanges be set in axle housing left and right two upper and be welded and fixed with it, two described axle tubes to be weldingly fixed on respectively on left and right two ends of axle housing and all to form girth joint.The present invention be by prior art beam front axle shell structure change Split type welding axle housing structure into, namely axle tube is not one with braking both flanges, but weld with axle housing respectively, due to braking flange by original directly change into being sleeved on axle housing with the welding edges of axle housing weld again, in order to keep braking the original installation site of flange, therefore the assembly length of axle housing needs proper extension, then the end of axle housing is welded with axle tube and weld forms girth joint, this structure makes axle housing vulnerable part (girth joint) away from leaf spring by the position changing girth joint, the vertical bending coefficient of WV-dangerous section place (near spring perch) axle housing is diminished and reaches the object improving axle case assy quality.
Such scheme volume is improved to further:
The steel plate of described axle housing adopts the steel plate of 12-14mm, and is preferably 16MnL steel plate;
Because axle tube and braking flange are welded on axle housing, and axle housing length increases, girth joint is away from spring block, and the sheet metal thickness of axle housing calculates through traditional mechanics, experimental verification analysis and simulation contrast means, confirm its thickness of slab can boundary between 12-14mm.
Below provide a kind of concrete driving axle housing assembly: the wheelspan of described driving axle housing assembly is 1.86m, in two spring blocks, distance is in the heart 1.03m, and the spacing of two girth joints is 1.46m, and spring block place axle housing cross-sectional area is 145mm × 160mm.
Compared with prior art, the utility model changes to present Split type welding axle case assy by original integral type, for this reducing the manufacturing cost of axle housing, decrease the overall weight (steel plate thickness after improvement and the sectional area of axle housing all little than prior art) of car load, reduce fuel oil consumption, adapt to the development tendency of auto parts and components.
