Abstract
The utility model provides a front auxiliary frame, front auxiliary frame includes piece and sub vehicle frame time piece on the sub vehicle frame, the piece is equipped with a first turn -ups on the sub vehicle frame, the piece passes through on the sub vehicle frame first turn -ups with sub vehicle frame piece down welds integratively each other. The utility model discloses front auxiliary frame has adopted side reinforcing plate derived structure, can satisfy front auxiliary frame's rigidity, strength requirement. The material that side reinforcing plate structure had utilized last piece need amputate originally carries out turn -ups beading piece under the sub vehicle frame and forms, has improved material utilization rate to only need a welding seam in the junction, saved the cost of side reinforcing plate mould simultaneously.
Description
Technical field
The utility model relates to automotive field, particularly a kind of fore sub frame.
Background technology
In automotive field, fore sub frame is important chassis structure part.For its effect in vehicle travel process of good performance, require that subframe has certain Rigidity and strength.Along with being growing more intense of industry competition, in product design process, not only to consider to meet properties of product requirement, also need to continue to optimize version, reduce product manufacturing productive costs.
Fig. 1 is the birds-eye view of traditional fore sub frame in prior art.Fig. 2 is the lateral plan of traditional fore sub frame in prior art.Fig. 3 is part A enlarged drawing in Fig. 2.
As shown in Figure 1 to Figure 3, fore sub frame 10 has subframe upper slice 11 and subframe bottom sheet 12 to be welded.In actual production, generally for the rigidity, the requirement of strength that meet fore sub frame 10, need in subframe 10 both sides to arrange side brace panel 13.This brace panel 13 needs and subframe upper slice 11 and bottom sheet 12 are welded.In addition, due to the existence of side brace panel 13, so need the mould of a secondary brace panel.This traditional reinforcement structure is that brace panel and subframe fluctuating plate are welded, and it exists upper and lower two weld seams, and there is this sub-part of brace panel, causes the complicated and defect that cost is high of processing and fabricating.
Utility model content
The technical problems to be solved in the utility model adopts side brace panel processed complex in fore sub frame and the high defect of cost to overcome in prior art, provides a kind of fore sub frame.
The utility model solves above-mentioned technical matters by following technical proposals: a kind of fore sub frame, its feature is, described fore sub frame comprises subframe upper slice and subframe bottom sheet, described subframe upper slice or described subframe bottom sheet are provided with one first flange, described subframe upper slice is welded to each other integral by described first flange and described subframe bottom sheet, or described subframe bottom sheet is welded to each other integral by described first flange and described subframe upper slice.
Preferably, described first flange is the flange of turnover downwards.
Preferably, the rear end of described fore sub frame is provided with the second flange.
Preferably, described first flange is relative with described second flange, and the height of described first flange equals the height of described second flange.
Positive progressive effect of the present utility model is: the utility model fore sub frame have employed side brace panel derived structure, can meet the rigidity of fore sub frame, requirement of strength.Described side brace panel structure make use of material that a script need excise and carries out flange and be welded direct to subframe bottom sheet and form, and improves stock utilization, and only needs a weld seam in junction, eliminate the cost of side brace panel mould simultaneously.
Accompanying drawing explanation
The above and other feature of the utility model, character and advantage are by more obvious by what become below in conjunction with the description of drawings and Examples, and Reference numeral identical in the accompanying drawings represents identical feature all the time, wherein:
Fig. 1 is the birds-eye view of traditional fore sub frame in prior art.
Fig. 2 is the lateral plan of traditional fore sub frame in prior art.
Fig. 3 is part A enlarged drawing in Fig. 2.
Fig. 4 is the connection structure schematic diagram of side brace panel and upper and lower flange in the utility model fore sub frame.
Detailed description of the invention
For above-mentioned purpose of the present utility model, feature and advantage can be become apparent, below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is elaborated.
Set forth a lot of detail in the following description so that fully understand the utility model, but the utility model can also adopt other to be different from alternate manner described here to implement, therefore the utility model is not by the restriction of following public specific embodiment.
Fig. 4 is the connection structure schematic diagram of side brace panel and upper and lower flange in the utility model fore sub frame.
As shown in Figure 4, disclose a kind of fore sub frame 20 in an embodiment of the present utility model, it comprises subframe upper slice 21 and subframe bottom sheet 22.Be provided with one first flange 23 at subframe upper slice 21, subframe upper slice 21 is welded to each other integral by the first flange 23 with subframe bottom sheet 22.Or be provided with one first flange in subframe bottom sheet 22, subframe bottom sheet 22 is welded to each other integral by described first flange and subframe upper slice 21.Above-mentioned two kinds of modes can realize the integral structure of the utility model fore sub frame.
Preferably, the first flange 23 is the flange of turnover downwards herein.In addition, the rear end of fore sub frame 20 is provided with the second flange (not shown).Can the first flange 23 is set to relative with described second flange, and the height of the first flange 23 equal the height of described second flange.
According to the description of said structure, the subframe upper slice that the utility model fore sub frame adopts down does a flange, and a weld seam is welded to bottom sheet and forms.There is the second flange in the rear end due to fore sub frame, so the first flange of front end make use of the material originally needing excision, not only increases stock utilization like this, also eliminate the material usage of side brace panel, eliminate the die cost of side brace panel simultaneously.
In sum, the utility model fore sub frame have employed side brace panel derived structure, can meet the rigidity of fore sub frame, requirement of strength.Described side brace panel structure make use of material that a script need excise and carries out flange and be welded direct to subframe bottom sheet and form, and improves stock utilization, and only needs a weld seam in junction, eliminate the cost of side brace panel mould simultaneously.
Although the foregoing describe detailed description of the invention of the present utility model, it will be understood by those of skill in the art that these are only casehistorys, protection domain of the present utility model is defined by the appended claims.Those skilled in the art, under the prerequisite not deviating from principle of the present utility model and essence, can make various changes or modifications to these embodiments, but these change and amendment all falls into protection domain of the present utility model.
