Description
Technical field
The utility model relates to automotive field, particularly relates to a kind of side bar for automobile shaped as frame subframe, and comprises its shaped as frame subframe.
Background technology
In prior art, the subframe of high-level car mostly is shaped as frame subframe, in order to allow attachment face before Control arm hold the front lining of Control arm, often needs on its side bar, offer a pit, for holding the front lining of Control arm.
Fig. 1 is the local axis side view of the side bar of traditional shaped as frame subframe.As shown in Figure 1, the side bar 10 of traditional shaped as frame subframe welds by side bar upper slice 11 and side bar bottom sheet 12 framework forming hollow.Side bar upper slice 11 offers a pit 13.The both sides of pit 13 have in skewed attachment face 14, and attachment face 14 with the formation corner region, front end 15 of pit 13 intersection.
Fig. 2 is the part sectional view of the side bar of traditional shaped as frame subframe.As shown in Figure 2, side bar upper slice 11 and side bar bottom sheet 12 are welded to each other and form weld seam 111,112.The madial wall of pit 13 welds with side bar bottom sheet 12, forms weld seam 113.Control arm connector bushing 20 is soldered in pit 13, forms weld seam 114.The structure of this pit can bring following problem:
One, this pit difficult forming, local material reduction is high, easily ftractures when shaping.
Two, pit is subject to structural limitations, little with the gap of Control arm, shaping rear easy resilience.
Three, in vehicle movement process, Control arm easily and subframe interfere.
Four, can the structure of generating strap wedge angle at the intersection of pit and Control arm front lining mounting plane, cause stress to be concentrated.In addition, the in test easy Cracking Failure of this intersection, bowl configurations does not improve overall intensity, but result in the increase of subframe overall weight.
Utility model content
The technical problems to be solved in the utility model is the side bar shaping structures difficulty in order to overcome shaped as frame subframe in prior art, and the defect of easy Cracking Failure, provides a kind of side bar for shaped as frame subframe.
The utility model solves above-mentioned technical matters by following technical proposals: a kind of side bar, for the shaped as frame subframe of automobile, described side bar comprises the side bar upper slice and side bar bottom sheet that are welded to each other up and down, its feature is, described side bar upper slice has the Control arm front lining attachment face in downward-sloping shape, described Control arm front lining attachment face is for installing Control arm connector bushing, described side bar upper slice and described side bar bottom sheet offer recess at described attachment face place, described side bar also comprises brace panel, described brace panel is fixed in described recess, described brace panel is also provided with the connecting portion for fixing Control arm connector bushing.
Preferably, described connecting portion is be opened in the groove on described brace panel, the shape of described groove and the form fit of described Control arm connector bushing.
Preferably, described brace panel is half frame-type.
Preferably, the top and bottom of described brace panel are welded with described side bar upper slice and described side bar bottom sheet respectively.
Preferably, described connecting portion is in the left and right sides of described brace panel, and described connecting portion mates with described Control arm connector bushing and welds.
The utility model additionally provides a kind of shaped as frame subframe, and its feature is, it comprises side bar as above.
Positive progressive effect of the present utility model is: the structure of the utility model side bar has lightweight, the features such as technique is simple, intensity is high, arrangement space is large.And the structure of described side bar is unique reliable, can all types of front lining of suitable solution arm, meet different Control arm motion space requirements well.In addition, the shaped as frame subframe of described side bar is adopted effectively can to reduce the overall weight of subframe.

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 local axis side view of the side bar of the utility model shaped as frame subframe.Fig. 4 is the local axis side view of the side bar of the utility model shaped as frame subframe.As shown in Figure 3 and Figure 4, the utility model side bar is mainly used in the shaped as frame subframe of automobile, and side bar 30 comprises the side bar upper slice 31 and side bar bottom sheet 32 that are welded to each other up and down.Side bar upper slice 31 has the Control arm front lining attachment face 34 in downward-sloping shape, and Control arm front lining attachment face 34 is here for installing Control arm connector bushing 40.Side bar upper slice 31 and side bar bottom sheet 32 offer recess 35 at Control arm front lining attachment face 34 place, in order to dodge the front lining of Control arm, and ensure that Control arm is when vehicle movement and the dynamic clearance of subframe.Side bar 30 also comprises brace panel 33, is fixed in recess 35 by brace panel 33.
Fig. 5 is the structural representation of brace panel in the side bar of the utility model shaped as frame subframe.As shown in Figure 5, brace panel 33 is half frame-type structure, welds respectively in the upper end 331 of brace panel 33 and lower end 332 with side bar upper slice 31 and side bar bottom sheet 32.Brace panel 33 is also provided with the connecting portion for fixing Control arm connector bushing 40.Described connecting portion is the groove 333 be opened on brace panel 33, preferably the shape of groove 333 and the form fit of Control arm connector bushing 40.In addition, described connecting portion is in the left and right sides of brace panel 33, and described connecting portion mates with Control arm connector bushing 40 and welds.Booster action can be played to the structure of side bar 30 and sleeve pipe 40 so simultaneously.
In addition, the utility model additionally provides a kind of shaped as frame subframe, and it comprises side bar 30 as above.
The side bar structure of above-mentioned shaped as frame subframe has the features such as lightweight, technique is simple, intensity is high, arrangement space is large, and its structure is unique reliable, can the front lining of various different size of suitable solution arm, meets different Control arm motion space requirements.
The side bar of the utility model shaped as frame subframe does not have attachment point place before Control arm to adopt establishing of pit
Meter, but the side bar upper slice at this place and side bar bottom sheet are hollowed out, increase the brace panel be connected with side bar upper slice in inner side simultaneously.Groove corresponding with on brace panel for the sleeve pipe side of Control arm front lining hold-down bolt is welded simultaneously.The defects such as the shaping difficulty that this solves bowl configurations is large, be difficult to Control arm gap to ensure, undercapacity, but also effectively can reduce the overall weight of subframe.
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.
