Abstract
The utility model discloses a kind of for the vehicle frame on heavy motor vehicle, comprise that left and right two sliver transvers sections are flute profile longeron and are fixed on the crossbeam between two crossbeams, the notch of every flute profile longeron welds a hush panel and forms box-shaped, the two inner side of flute profile longeron and hush panel is welded with respectively several nuts, and beam welding is in the hush panel of longeron.By above setting, the utility model has reduced the impact of the factors such as sunlight, water, has extended service life.
Description
Technical field
the utility model relates to vehicle frame, particularly a kind of for the vehicle frame on heavy motor vehicle.
Background technology
existing heavy vehicle frame is generally by crossbeam and left and right flute profile longeron and forms trapezium structure, and Main Function is the parts such as bearing goods and layout power, transmission, and this device generally should have certain intensity, rigidity and resistance to bending.For superduty vehicle, be particularly operated in the vehicle under severe road conditions, to the properties of vehicle frame, require higher.Generally there is the longeron of increasing end face height and strengthen two kinds of solutions of longeron material thickness, first method is very effective to improving vehicle frame performance, but has raised the center of gravity of car man, has increased safety hazard, second method is because thickness increase limited resource is more, limited to vehicle frame performance impact.
Summary of the invention
the utility model, in order to make up the deficiencies in the prior art, provides a kind of vehicle frame that significantly improves vehicle frame performance and do not raise the heavy motor vehicle at vehicle frame center.
the utility model is achieved by the following technical solution:
the vehicle frame of heavy motor vehicle of the present utility model, comprises two the flute profile longerons in left and right and is fixed on the crossbeam between two crossbeams, and the notch of every flute profile longeron welds a hush panel and forms box-shaped; The two inner side of flute profile longeron and hush panel is welded with respectively three nuts, and beam welding is in the hush panel of longeron; Flute profile longeron is by press device punch forming, hush panel is welded in flute profile longeron inner side by welding gear section, at least two crossbeams are set, hush panel by left-right longeron by two box girders fixed be ladder type frame, the air pipe of vehicle, wirning harness are closed in box-shaped longeron inner chamber, the welded nut of longeron and hush panel welded nut are separate, and longeron and crossbeam are spheroidal graphite iron and make.。
the vehicle frame of heavy motor vehicle of the present utility model, convenient for other parts are installed, the two inner side of flute profile longeron and hush panel is welded with respectively several nuts.
the vehicle frame of heavy motor vehicle of the present utility model, for in-use performance reaches best, beam welding is in the hush panel of longeron.
the beneficial effects of the utility model are, can significantly improve vehicle frame performance, and can not raise frame mass centre, and it is inner that the air pipe of vehicle, wirning harness are closed in the box-shaped of longeron substantially, reduced the impact of the factors such as sunlight, water, extended service life.
Accompanying drawing explanation
fig. 1 is cross section structure schematic diagram of the present utility model.
in figure 1, longeron 2, hush panel 3, crossbeam 4, nut.
The specific embodiment
as shown in Figure 1, the utility model comprises that left and right two sliver transvers sections are flute profile longeron 1 and are fixed on the crossbeam 3 between two crossbeams, the notch of every flute profile longeron 1 welds a hush panel 2 and forms box-shaped, crossbeam 3 is welded in hush panel, and the two inner side of flute profile longeron 1 and hush panel 2 is welded with respectively several nuts 4.
the vehicle frame of heavy motor vehicle of the present utility model, the cross sectional shape of longeron 1 is that burn-on hush panel 2 of flute profile longeron forms box-shapeds, flute profile longeron can be by common one-tenth structural section or press device punch forming, hush panel 2 can be welded in flute profile longeron inner side by common welding gear section, the crossbeam 3 of some is set as required, the hush panel by left-right longeron by two box girders fixed be ladder type frame.The air pipe of vehicle, wirning harness are closed in box-shaped longeron 1 inner chamber substantially, have reduced the impact of the factors such as sunlight, water.Welded nut 4 and hush panel 2 welded nuts of longeron 1 are separate, facilitate the installation of inside and outside parts.
