Automobile steering drive axle

Abstract

The invention relates to an automobile steering drive axle. The automobile steering drive axle is compact in structure, big in transmission ratio, strong in bearing force, and high in integration level, and can match up with motorcycle types with different wheel treads and hanging structures. The automobile steering drive axle comprises an axle shell assembly, a main decelerator assembly arranged in the middle part of the axle shell assembly, and wheel side assemblies arranged at both ends of the axle shell assembly; the axle shell assembly comprises four steel plates and a back cover; the four steel plates are respectively welded together and formed to be an axle body; the section of the axle body forms a rectangular hollow cavity, the back cover is fixed at the back face of the axle body; the main decelerator assembly comprises a main decelerator shell, a bearing base, an input flange, an active bevel gear, a driven bevel gear and a differential device; the upper face of the main decelerator shell is provided with a bearing installing hole, and the lower bottom face is provided with a differential bearing installing table; two oil baffles are arranged between the bearing base installing hole of the decelerator shell and the bearing installing table of the differential device; the oil baffles are in a splayed shape from top to bottom, and its outsides are in a wave form.

Description

technical field [0001] The invention relates to an improvement of a drive axle structure, in particular to an automobile steering drive axle. Background technique [0002] At present, domestic heavy-duty vehicles and special vehicle steering drive axles require a large overall speed ratio, frequent changes in the whole bridge parameters (wheelbase, suspension center distance, etc.), strong bearing capacity, and auxiliary connectors (steering power cylinder bracket, corner angle, etc.) There are many sensor brackets, etc.), the axle housing mold changes frequently, the cost is high, the production cycle is long and the overall layout is prone to interference. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the present invention provides a novel steering drive axle, which has a compact structure, a large transmission ratio, a strong bearing capacity, and a high degree of integration, and can match vehicles with different wheel bases and suspen...
