Description
Technical field
The utility model relates to automotive axle field, and what especially relate to is a kind of rear axle in vehicle shell.
Background technology
Along with the continuous attention of automobile to safety, energy-saving and environmental protection, rear axle in vehicle is as a critical component of car load, the safe handling of the quality of its product on car load and the impact of vehicle performance are very large, therefore rear axle in vehicle are carried out to actv. optimal design and are very important.The transport trolley of transport bridge, requires its speed steady slowly, and strength is large; At present back axle in use, because output torque is little, load-carrying deficiency; Axle housing Lack of support, middle rear-axle casing easily ftractures.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and the rear axle in vehicle shell of a kind of low speed, high moment of torsion is provided.
For achieving the above object, technical solution of the present utility model is: a kind of rear axle in vehicle shell, comprise housing, and the two ends of described housing are all socketed with axle tube, the bottom of described housing is provided with strengthening rib, and the external part outside face of described axle tube is provided with spline structure.
Preferably, described housing middle part is provided with seam, and described seam diameter is 395-400mm.
Preferably, the screw quantity on described seam flange is 12-16, and the screw quantity on the little flange that described housing two ends are connected with retarder is 8-12.
Preferably, described housing and axle tube are fixed by locating dowel pin.
Preferably, totally 4 and be located at respectively front and back side and the left and right sides of housing below of described strengthening ribs.
By adopting above-mentioned technical scheme, the beneficial effects of the utility model are: the outside face of axle tube external part of the present utility model end is spline structure, spline housing is installed, is subtracted differential system for installation and support wheel limit, this structure can underspeed, increase propulsive effort; Seam diameter is greater than 395mm, and the more retarder of high pulling torque can be installed; Housing below increases by 4 strengthening ribs, increases casing rigidity, prevents that housing from use ftractureing.
