In crossbeam assembly structure of the present utility model, the top airfoil of cross-beam body is the top airfoil that there is depression at middle part, and add the spacing between change speed gear box drain pan and front propeller shaft, depressed area space is in order to hold change speed gear box drain pan; Cross-beam body depressed area place welding brace panel I, brace panel I design end 4 plug welding holes and cross-beam body plug welding to improve the reliability of crossbeam, and brace panel I and other contact site of cross-beam body 1 adopt to stitch and weld; Cross-beam body and crossbeam adapter plate adopt to stitch and weld; Cross-beam body end appropriate design L-type reinforced rib, L-type reinforced rib and crossbeam adapter plate adopt to stitch and weld, on L-type reinforced rib and cross-beam body 1, plug welding hole carries out plug welding, and the appropriate design of L-type reinforced rib effectively improves the bulk strength of crossbeam assembly and the connection reliability of crossbeam assembly and flat spring bracket; Brace panel I is designed with reduction stress in middle part and concentrates hole, to reduce the torsional stiffness in the middle part of crossbeam assembly, and then the welding stress reducing brace panel and cross-beam body end is concentrated; At cross-beam body two ends bottom welding brace panel II, to improve torsion stiffness and the intensity of crossbeam assembly; Crossbeam adapter plate was designed with pin-and-hole, and to provide the installing space of bearing pin and fluted nut, the fitting operation space of bearing pin and fluted nut for convenience, adopts a channel beam body arranged apart, makes it meet enough operational spaces; Crossbeam assembly two ends and flat spring bracket installation position are that inclined design is to facilitate installation.
The each parts of this crossbeam assembly all adopt plate or sheet metal component, and each sheet metal component structure is simple, can direct bending and molding after blanking, and drop into without the need to mould, simply, cost is lower for process for machining and manufacturing.
During installation, first flat spring bracket is connected with chassis side rail, then between the flat spring bracket of left and right, crossbeam assembly is installed; Whole use bolt connects, and structure is simple, good manufacturability, is easy to assembling.
The beneficial effects of the utility model are: this utility model to efficiently solve when driving engine location is lower spacing between change speed gear box drain pan and front propeller shaft owe well-to-do cause beam structure layout design difficulty herein problem and fitting operation space fully, and this design ensure that intensity and the torsional stiffness of crossbeam assembly to the utmost.
