Rectangular square tube beam.
The principle of the present invention is described as follows：
1st, due to being limited by vehicle frame second cross beam 13, the arrangement of turning machine 4 can influence the position of steering drag link 6, therefore
Consider the design feature of vehicle frame second cross beam 13, and frame system and frame 1 is using the structure phase of the vehicle frame second cross beam 13 of the design
To consolidating, often it is used, accordingly, with respect to turning machine prone type, turning machine lateral recumbent posture easily to arrange and the height of low driver's compartment
The relative high point of degree；The design is applied to vehicle of the vehicle frame connection vehicle body for unified full bearing structure, and prior art is more suitable for
Vehicle frame is the vehicle of full bearing structure, and therefore, the actual scope of application of the design is wider.
2nd, flat board bending part is used referring to Fig. 3, the steering gear bracket 41, the upper end of steering gear bracket 41 is provided with folding
Crimp 413, front end are provided with preceding bending edges 414, and rear end is provided with rear bending edges 415, upper bending edges 413 and frame side member 17
Lower surface mutually weld, the rear end face of preceding bending edges 414 and the second side vertical beam 145 mutually welds, rear bending edges 415 and vehicle frame second
The front end face of crossbeam 13, the front end face of rear vertical beam 162 are homogeneously welded, and steering gear bracket 41 strengthen admittedly by three Edge Bends
It is fixed；The adjacent both sides of steering gear bracket 41 all bending when, the presence of bending fillet is had among adjacent both sides, centre must reserve sky
Between, therefore, two corners of bending form engraved structure, i.e., preceding shape between the upper end of bending edges 414 and the front end of upper bending edges 413
Cheng Youqian bendings breach 416, formed with rear bending breach between the rear end of upper bending edges 413 and the upper end of rear bending edges 415
417, preceding bending breach 416, rear bending breach 417 are process structures, facilitate bending flange.
