Technical field
The utility model relates to automobile manufacturing field, particularly a kind of automobile front subframe.
Background technology
In the prior art, fore sub frame is the important component part in car chassis system, it carry driving engine and steering swivel system, and is connected to stabilizer rod, Control arm and vehicle body.
Fig. 1 is the integral structure schematic diagram of orthodox car fore sub frame.As shown in Figure 1, traditional automobile front subframe is welded by the back rest 10, left and right side bar 20, front-axle beam 30 and each mounting bracket (not shown).Wherein, the back rest 10 and front-axle beam 30 are respectively used to the load carrying driving engine, steering box, stabilizer rod, and side bar 20 is mainly used in the load carrying front and back Control arm.
Fig. 2 is the decomposing schematic representation that in orthodox car fore sub frame, side bar is connected with the back rest.As shown in Figure 2, the side bar 20 in orthodox car fore sub frame is welded to form by side bar bottom sheet 21 and side bar upper slice 22, and the back rest 10 is welded to form by back rest bottom sheet 11 and the back rest upper slice 12, and has two sleeves 40 in rear Control arm installation region inner support.The two ends of sleeve 40 are welded with side bar bottom sheet 21 and side bar upper slice 22 respectively, and this region is also connected with the back rest 10 simultaneously.
The load that this structure makes rear Control arm hard spot position bear, and the load that the back rest bears all conducts to side bar bottom sheet 21 and side bar upper slice 22 by weld seam and sleeve, therefore side bar affords very large application force.But consider lightweight and punching press requirement, side bar often can not select very thick punching, therefore usually there will be area of stress concentration in the junction of side bar and the back rest, causes this area failures.
Utility model content
The technical problems to be solved in the utility model is that the structure in order to overcome automobile front subframe in prior art easily occurs that stress concentrates the defect causing losing efficacy, and provides a kind of automobile front subframe.
The utility model solves above-mentioned technical matters by following technical proposals: a kind of automobile front subframe, comprise welding successively and form the front-axle beam of framed structure, left and right side bar and the back rest, described side bar comprises side bar upper slice and side bar bottom sheet, the described back rest comprises the back rest upper slice and back rest bottom sheet, described side bar upper slice, the described back rest upper slice, described back rest bottom sheet and described side bar bottom sheet are welded to each other successively and are integrated, and form a hollow region, sleeve is provided with in described hollow region, its feature is, at least one support is also fixed with in described hollow region, described support is positioned at the join domain of described side bar and the back rest.
Further, in another preferred embodiment, described support is U-shaped support.
Further, in another preferred embodiment, described U-shaped support comprises two sidepieces and a bottom, and described sidepiece is vertically fixed on the both sides of described bottom.
Further, in another preferred embodiment, described bottom is welded with described side bar bottom sheet, and described two sidepieces weld with described side bar upper slice respectively.
Further, in another preferred embodiment, described bottom is connected with the plug welding of described side bar bottom sheet.
Further, in another preferred embodiment, the upper end of described sidepiece is arc-shaped curved surface, and the shape of described arc-shaped curved surface matches with the described side bar upper slice inner wall shape of corresponding weld.
Further, in another preferred embodiment, the length of described U-shaped support is 4.5cm-5.5cm, and wide is 3cm-4cm.
Positive progressive effect of the present utility model is: the utility model, by arranging support in the join domain of side bar and the back rest, effectively enhances the intensity of lower rear Control arm and steering box load.After described automobile front subframe improves, the rigidity of structure improves 50%, and make the stress of part weakness zone obtain effective reinforcement, and weight distribution is more reasonable, the risk of part failure also obviously reduces.

Detailed description of the invention
Preferred embodiment of the present utility model is provided, to describe the technical solution of the utility model in detail below in conjunction with accompanying drawing.
Fig. 3 is the decomposing schematic representation that in the utility model automobile front subframe, side bar is connected with the back rest.Fig. 4 is the structural representation of Fig. 3 medium-height trestle.
As shown in Figure 3, the utility model automobile front subframe comprises the front-axle beam (not shown), left and right side bar 20 and the back rest 10 that weld successively and form framed structure.Side bar 20 comprises side bar upper slice 22 and side bar bottom sheet 21, and the back rest 10 comprises the back rest upper slice 12 and back rest bottom sheet 11.Side bar upper slice 22, the back rest upper slice 12, back rest bottom sheet 11 and side bar bottom sheet 21 are welded to each other successively and are integrated, and form a hollow region A, are provided with sleeve 40 in hollow region A.Two sleeves 40 are provided with side by side in the present embodiment.Especially, in hollow region, be also fixed with at least one support 50 in A, make support 50 be positioned at the join domain of side bar 20 and the back rest 10.Obtain according to simulation analysis result, the join domain of side bar 20 and the back rest 10 is the high stress areas of automobile front subframe.Therefore support 50 is arranged on this join domain and effectively can strengthens the intensity that side bar and the back rest bear application force.
As shown in Figure 4, support 50 is preferably U-shaped support.Described U-shaped support comprises two sidepieces 51 and a bottom 52, and sidepiece 51 is vertically fixed on the both sides of bottom 52.Composition graphs 3 again, bottom 52 is welded with side bar bottom sheet 21, and two sidepieces 51 weld with side bar upper slice 22 respectively.Herein, bottom 52 is preferably plug welding with side bar bottom sheet 21 and is connected.This welding manner can ensure to be welded as a whole securely between bottom 52 and side bar lower plate 21 effectively.
In addition, further, the upper end of sidepiece 51 can be set to arc-shaped curved surface, and the shape of described arc-shaped curved surface matches with side bar upper slice 22 inner wall shape of corresponding weld.According to actual service condition, can be 4.5cm-5.5cm by the length of described U-shaped support, wide be 3cm-4cm.
In sum, the utility model automobile front subframe can strengthen the loadintensity of lower rear Control arm and steering box effectively by said structure.Rigidity increases by 50%, and the stress of part weakness zone is effectively strengthened, and weight distribution is more reasonable, and the risk of part failure also obviously reduces.
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.
