Abstract
The utility model relates to subframe girder constructions, belong to the technical field of Automobile Design and manufacture.The subframe girder construction of the utility model, including reinforcing beam assembly, right vertical beam assembly, front beam assembly, left stringer assembly and rear cross beam assembly, front beam assembly includes front beam upper plate and front beam lower plate, front beam lower plate and front beam upper plate, right vertical beam assembly and left stringer assembly are welded to connect, the both ends of front beam upper plate are provided with butterfly or wavy shaped configuration, and butterfly or wavy shaped configuration and the front top of right vertical beam assembly and left stringer assembly weld to form butterfly or waveform weld seam.Front beam assembly in the subframe girder construction of the utility model is fixed by welding manner and left stringer assembly and right vertical beam assembly, and welding edge is changed to butterfly or wavy shaped configuration by straight line, significantly increases fusion length, improves weld strength.
Description
Technical field
The utility model relates to the technical fields of Automobile Design and manufacture, and more specifically, the utility model relates to one kind
Subframe girder construction.
Background technique
As shown in Figure 1, a kind of subframe girder construction in the prior art include reinforcing beam assembly 1, right vertical beam assembly 2,
Front beam assembly 3, left stringer assembly 4 and rear cross beam assembly 5.Therein, the welding edge and weld seam of front beam assembly are straight line,
Since fusion length is short, weld strength is lower, is easy to appear weld cracking phenomenon.
Utility model content
In order to solve above-mentioned technical problem in the prior art, the purpose of this utility model is to provide a kind of subframe beams
Body structure.
A kind of subframe girder construction, including reinforcing beam assembly, right vertical beam assembly, front beam assembly, left stringer assembly with
And rear cross beam assembly, the reinforcing beam assembly setting are total in right vertical beam assembly, front beam assembly, left stringer assembly and rear cross beam
At in the girder construction of composition and respectively with the right vertical beam assembly, front beam assembly, left stringer assembly and rear cross beam assembly
It is welded and fixed；The front beam assembly includes front beam upper plate and front beam lower plate, it is characterised in that: the front beam lower plate with
Front beam upper plate, right vertical beam assembly and left stringer assembly are welded to connect, and the both ends of the front beam upper plate are provided with butterfly or wave
Shape wave structure, the butterfly or wavy shaped configuration and the front top of the right vertical beam assembly and left stringer assembly weld to form butterfly
Shape or waveform weld seam.
Wherein, there is fillet in the butterfly or wavy shaped configuration, and the half-angle of the fillet is more than or equal to 5mm.
Compared with prior art, the subframe girder construction of the utility model there are following the utility model has the advantages that
Front beam upper plate and right vertical beam assembly and left stringer assembly in the subframe girder construction of the utility model weld
While being changed to butterfly or wavy shaped configuration by straight line, fusion length is significantly increased, improves weld strength.

Specific embodiment
Subframe girder construction described in the utility model is further elaborated below with reference to specific embodiment, with
It is more complete, accurate and deep that help those skilled in the art conceives the utility model of the utility model, technical solution has
Understand.
Embodiment 1
As in Figure 2-4, the subframe girder construction of the present embodiment, including it is reinforcing beam assembly 10, right vertical beam assembly 20, preceding
Crossbeam assembly 30, left stringer assembly 40 and rear cross beam assembly 50.The reinforcing beam assembly 10 is arc-shaped and is arranged on the right side
In the girder construction that stringer assembly 20, front beam assembly 30, left stringer assembly 40 and rear cross beam assembly 50 are constituted and respectively with
The right vertical beam assembly 20, front beam assembly 30, left stringer assembly 40 and rear cross beam assembly 50 are welded and fixed.As shown in figure 5,
Front beam assembly includes front beam upper plate and front beam lower plate.Front beam lower plate passes through welding and right vertical beam assembly 20 and left stringer
The front bottom end of assembly 40 is fixedly connected, and the both ends of front beam upper plate are provided with butterfly or wavy shaped configuration (such as Fig. 3 circle portion
Point), the front top of the butterfly or wavy shaped configuration and the right vertical beam assembly and left stringer assembly weld to be formed butterfly or
Waveform weld seam 62, compared to linear welding edge, butterfly or wavy weld line significantly increase fusion length, mention
High weld strength.As shown in figure 4, there is fillet 61, and the half-angle of the fillet is big in the butterfly or wavy shaped configuration
In being equal to 5mm, it can so guarantee that soldering appliance enters welding root, prevent root from causing welding defect, and can prevent from welding
Stress is concentrated.In addition sequential welding or segmentation weldering can be used in welding manner.Preceding cross in the subframe girder construction of the present embodiment
Beam assembly is fixed by welding manner and left stringer assembly and right vertical beam assembly, enhances the integrally-built bonding strength of beam body.
For the ordinary skill in the art, specific embodiment has only carried out exemplary retouch to the utility model
It states, it is clear that the utility model specific implementation is not subject to the restrictions described above, as long as using the method concept of the utility model
The improvement of the various unsubstantialities carried out with technical solution, or the not improved conception and technical scheme by the utility model are direct
Applied to other occasions, it both is within the protection scope of the present invention.
