The side beam frame is a solid and rigid frame composed of two longitudinal beams on both sides and several cross beams connected by riveting or welding. Since the side beam frame is convenient for installing the body and arranging the assembly, it is conducive to the needs of modifying modified vehicles and developing a variety of vehicle models, so it is also more suitable for the design and use of frame beams of various commercial vehicles.

[0003] Since the existing commercial vehicle frame beams basically adopt a frame structure composed of two longitudinal beams located on both sides and a number of cross beams, the entire frame beam only has structural support in the horizontal and vertical directions. When the entire frame beam encounters an impact in the oblique side corner direction, the stress resistance of the entire frame beam is relatively poor, and the effect of resisting the force impact in the oblique side corner direction is poor. Summary of the invention

[0007] A reinforced structure loading through hole is opened at the side end of the bottom wall of the leaf spring beam rivet support sleeve; an inclined beam frame loading through hole is opened at the end of the impact stress reinforced inclined beam frame, and the end of the impact stress reinforced inclined beam frame is fixedly connected to the reinforced structure loading through hole by a loading screw and a fixing nut, and the reinforced end ring of the inclined beam frame is fixedly welded and installed at the end of the impact stress reinforced inclined beam frame.

[0008] Preferably, the loading screw fixes the leaf spring beam rivet sleeve and the anti-impact stress reinforced inclined beam frame by inserting into the reinforced structure loading through hole and the inclined beam frame loading through hole; the end of the loading screw is a hexagonal hole, and the fixing nut is located inside the reinforced end ring of the inclined beam frame.

[0009] Preferably, the middle body of the anti-impact stress strengthened inclined beam frame is a prismatic structure with an open top, and the end of the anti-impact stress strengthened inclined beam frame is a circular plate structure, and the side surface of the inclined beam frame strengthened end ring is fixed to the top of the side end of the anti-impact stress strengthened inclined beam frame.

[0010] Preferably, both ends of the anti-impact stress reinforced oblique beam frame are respectively fixedly connected to the diagonally opposite leaf spring beam rivet nails installed by two leaf spring bracket beams.

[0011] Preferably, a front cross beam support sleeve is riveted and fixed to the front end of the longitudinal beam sleeve by longitudinal beam rivet nails, and the front cross beam support sleeve is located on the inner side of the longitudinal beam sleeve.

[0012] Preferably, the top wall and the bottom wall of the front cross beam support sleeve are riveted with front cross beam rivet nails, and the front cross beam sleeve frame is riveted and installed on the inner side of the front cross beam support sleeve through the front cross beam rivet nails.
