Abstract
The utility model discloses a kind of Lower control arm structure, comprise the Lower control arm body of metal plate punching, described Lower control arm body rear end is provided with bolt through-hole, middle part is welded with Lower control arm upper body, front end is welded with Lower control arm sleeve pipe, and the middle part of Lower control arm upper body and Lower control arm body is provided with brace panel.The utility model constitutes a complete enclosed construction due to Lower control arm body, Lower control arm upper body and brace panel, actv. improves the rigidity of Lower control arm body, ensure that whole Lower control arm is stressed more reasonable by the application of brace panel, avoid the appearance of high-stress concentration, add the reliability of Lower control arm.Integral structure quality is light, and rigidity is high, and load-carrying capacity is strong, and the leftover pieces that brace panel can adopt miscellaneous part to process are shaping, and cost is low, good in economic efficiency.
Description
technical field:
The utility model relates to automotive field, particularly relates to a kind of Lower control arm structure.
background technology:
For the requirement to automotive performance, increasing vehicle adopts independent rear suspension.Because superior performance, quality be light etc., advantage becomes the main flow suspension that middle and high end car selects to multi-link lever suspension fork.
At present, the multi-link lever suspension fork on market is main mainly with double leval jib and Five-Force Model.In layout, these suspensions can adopt a sturdy Lower control arm as the mounting structure of spring mostly.Spring case shock absorber is installed on Lower control arm by arranging of having.Such design benefit is that layout is compact, and take up room little, the space leaving miscellaneous part after suspension arrangement for is larger.Shortcoming is obvious too, because the parts such as spring have been arranged on Lower control arm, and the very large load that Lower control arm is born, in use, extremely easy cracking or fracture.
utility model content:
In order to make up prior art problem, the purpose of this utility model is to provide a kind of Lower control arm structure, has quality light, and the rigidity of structure is large, the low and high reliability of processing and manufacturing cost.
The technical solution of the utility model is as follows:
Lower control arm structure, it is characterized in that: the Lower control arm body comprising metal plate punching, described Lower control arm body rear end is provided with bolt through-hole, middle part is welded with Lower control arm upper body, front end is welded with Lower control arm sleeve pipe, and the middle part of Lower control arm upper body and Lower control arm body is provided with brace panel.
Described Lower control arm structure, it is characterized in that: described Lower control arm body is the fusiformis pot shell that middle wide two narrows gradually, the edge punching press of fusiformis pot shell has flange, the spring perch to upper overturning is provided with in the middle part of the base plate of fusiformis pot shell, spring perch front end is still provided with the lower bolt through-hole installing subframe, and the thickness of fusiformis pot shell is generally 2.5mm ~ 3.5mm.
Described Lower control arm structure, it is characterized in that: described Lower control arm upper body adopts sheet metal component to strike out the fusiformis plate with this mates of Lower control arm, the through hole corresponding with spring perch position is provided with in the middle part of fusiformis plate, through hole front end is provided with the upper bolt through-hole corresponding with lower bolt through-hole position, and the thickness of panel beating is 2.5mm ~ 3.5mm
Described Lower control arm structure, it is characterized in that: described brace panel is formed by metal plate punching, brace panel comprises the second brace panel of the first brace panel of the annular in spring perch position, square between upper and lower bolt through-hole, the two ends of the first brace panel, the second brace panel are all weldingly fixed between Lower control arm body and Lower control arm upper body, and the thickness of panel beating is generally 2.0mm ~ 2.5mm.
The utility model has the advantages that:
The utility model constitutes a complete enclosed construction due to Lower control arm body, Lower control arm upper body and brace panel, actv. improves the rigidity of Lower control arm body, ensure that whole Lower control arm is stressed more reasonable by the application of brace panel, avoid the appearance of high-stress concentration, add the reliability of Lower control arm; Integral structure quality is light, and rigidity is high, and load-carrying capacity is strong, and the leftover pieces that brace panel can adopt miscellaneous part to process are shaping, and cost is low, good in economic efficiency.
accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of Lower control arm body of the present utility model.
Fig. 3 is the structural representation of Lower control arm upper body of the present utility model.
Fig. 4 is the structural representation of brace panel of the present utility model.
