Abstract
The utility model relates to a C-shaped structure crossbeam of a truck, relating to a C-shaped structure crossbeam of a heavy truck, which has high strength and a light weight. The cross section of the crossbeam is in a C-shaped structure consisting of an upper wing plate, a stand plate and a lower wing plate, wherein the upper wing plate and the lower wing plate are mutually parallel, the stand plate is vertical to both the upper wing plate and the lower wing plate, and an upper arc-shaped transition section between the upper wing plate and the stand plate and a lower arc-shaped transition section between the stand plate and the lower wing plate are integrally connected. The thicknesses of the upper wing plate, the stand plate and the lower wing plate are all less than 4mm. The utility model has the beneficial effects that the crossbeam has no welded junction and good integrity, and has the characteristics of high tearing resisting degree, strong antifatigue degree and the like, and the light weight, high quality and high safety of the crossbeam of the truck are realized.
Description
Technical field
The utility model relates to a kind of crossbeam of high strength lightweight heavy motor vehicle C type structure.
Background technology
At present, known general heavy motor vehicle crossbeam is " worker " font structure, and it is welded by the bar shaped sheet material of cutting, processes time-consuming expense material, adopts flame cut and plasma cutting mode during the cutting batten, can produce a large amount of dust gases, has polluted environment.The weld bond unfairness of particularly welding crossbeam is bright and clean, and cracking causes the durability of product and aesthetic property not high easily.
Summary of the invention
The utility model is for providing a kind of C type lightweight automotive frame of the globality by high strength material.
The technical scheme that the utility model adopted is as follows: the C type structure that the cross section of this crossbeam is made of upper flange, riser and lower wing plate, upper flange and lower wing plate are parallel to each other, riser is all vertical with lower wing plate with upper flange, and last arc-shaped transition section between upper flange and riser and riser are connected with arc lower transition phase one between the lower wing plate.The thickness of upper flange, riser and lower wing plate all is no less than 4 ㎜.
The beneficial effects of the utility model do not have weld bond for this crossbeam, and good integrity has characteristics such as anti tear degree height, antifatigue degree are strong, to realize lightweight, high materialization, the high security of automotive frame.
Description of drawings
Accompanying drawing 1 is the utility model integral structure scheme drawing.
The specific embodiment
The utility model is whole strip structure, its cross section is C type structure, is connected with riser 3 one by last arc-shaped transition section 2 by upper flange 1, and riser 3 is connected with lower wing plate 5 one by arc lower transition phase 4, upper flange 1 is parallel with lower wing plate 5, and riser 3 is all vertical with lower wing plate 5 with upper flange 1.The utility model is got its length as required.For guaranteeing the intensity of crossbeam, the thickness of upper flange, riser, lower wing plate all is no less than 4 ㎜.It uses high strength S700MC rank low-carbon bainite lightweight material, at first plate of material is carried out the smooth processing of accuracy, cut itemize by the roll shaft circular cutter disk then, in the middle of the finishing process, discharge the own a part of internal stress of sheet material, the realization sheet material internal stress in cross section in length and breadth reaches balance, realize sheet material internal stress well-distributed purpose, for necessary internal condition is created in the following process moulding.Secondly, adopt the gradual step by step molding mode of tens of procedures of rolling forming process, the final lightweight C type channel-section steel that forms with certain radian.By tens of procedures, progressively make the process of high strength material distortion, releasable material internal stress progressively, guaranteeing under the situation that the high strength material inner structure is not damaged, the product of moulding promptly has internal stress rationally to be discharged and distributes, the radian of C type groove guarantees that through the science measuring and calculating the even science of bearing capacity distributes, and makes product have good fatigue resistance and stability in addition.
