Abstract
The present invention provides a kind of K fonts MacPherson type subframe, and it includes：Fore sub frame outside plate（1）With fore sub frame inner panel（2）Coordinate the subframe body for constituting, swing arm link is additionally provided with subframe body（3）, it is characterised in that：In fore sub frame outside plate（1）On be additionally provided with U-lag with swing arm corresponding matching（1a）, in U-lag（1a）The fore sub frame outside plate of side（1）On be also provided with cover U-lag（1a）Roller flower pad（4）.Simple structure of the present invention, it is easily manufactured, whole subframe assembly production cost is reduced, the advantages of lifting welding quality and precision, and can reduce the coverage of welding deformation and thermal stress during welding rolls flower pad.
Description
Technical field：
It is exactly specifically a kind of K fonts MacPherson type subframe the present invention relates to a kind of automobile component.
Background technology：
The left and right sides of automobile accessory frame is symmetrically connected with swing arm, and subframe is connected by swing arm with brake hub bracket.It is existing
There is the mounting post in technology on swing arm Large lining when being connected with fore sub frame outside plate, be mostly on fore sub frame outside plate
Mounting hole at be provided with filling pad and play position-limiting action.And this limit method is when mounted due to filling pad and roller flower pad
There is misalignment phenomenon in piece, be easily caused welding misalignment in three ply board spot welding, and the penetration rate of solder joint not enough, influences whole product
Energy and outward appearance.
The content of the invention：
The present invention is exactly to overcome deficiency of the prior art, there is provided a kind of K fonts MacPherson type subframe.
The present invention provides following technical scheme：
A kind of K fonts MacPherson type subframe, it includes：Fore sub frame outside plate coordinates the subframe for constituting with fore sub frame inner panel
Body, is also arranged with swing arm link on subframe body, it is characterised in that：Also it is arranged with fore sub frame outside plate
With the U-lag of swing arm corresponding matching, also it is provided with covering the roller flower pad of U-lag on the fore sub frame outside plate of U-lag side.
On the basis of above-mentioned technical proposal, there can also be technical scheme further below：
Described fore sub frame outside plate is integrated punch forming with U-lag.
Described roller flower pad is welded on the fore sub frame outside plate of U-lag side by 4 spot welding.
Invention advantage：
The present invention have simple structure, it is easily manufactured, whole subframe assembly production cost is reduced, by directly in preceding secondary car
U-lag and roller flower pad are set on frame outside plate, deficiency of the prior art is overcome, the matter welded in subframe production is improved
Amount and precision, and the advantages of can also reduce the coverage of welding deformation and thermal stress during welding rolls spends pad.
Particularly fore sub frame outside plate and U-lag is the direct punch forming of mould so that the installation of roller flower pad is by three layers
Plate spot welding is changed to two-ply spot welding, overcomes in the prior art, and filling pad is partially welded error herein, because direct punch forming can be with
Axiality is improved, lower swing arm is easier assembling, improves the precision of whole front overhang.
Brief description of the drawings：
Fig. 1 is overall structure diagram of the invention；
Fig. 2 is the lateral upward view in part of the invention.
Specific embodiment：
As shown in Figure 1, 2, a kind of K fonts MacPherson type subframe, it includes：Fore sub frame outside plate 1 is matched somebody with somebody with fore sub frame inner panel 2
Close the subframe body for constituting.
Swing arm link 3 is also arranged with subframe body, in the fore sub frame outside plate 1 of the side of swing arm link 3
On be also arranged with U-lag 1a with the mounting post corresponding matching on swing arm Large lining, outside the fore sub frame of U-lag 1a sides
Being additionally provided with plate 1 can cover the roller flower pad 4 of U-lag 1a.Described roller flower pad 4 is welded on U-lag 1a by 4 spot welding
The circular hole center of circle and U-lag 1a bottoms circular arc on roller flower pad 4 on the outer surface of the fore sub frame outside plate 1 in outside and described
The center of circle it is coaxial.
Described fore sub frame outside plate 1 is integrated punch forming and is made with U-lag 1a.
Shown to carrying out CAE analysis at U-lag 1a in the present invention, its vertical operating mode numerical value is 175.8MPa, steering situation
Numerical value is 272MPa, meets design requirement.And here in connection with bench test and actual road test, a grade flange is opened herein and is not occurred
The phenomenons such as deformation, solder joint tear, from it is theoretical with meet design requirement in practice.
