Detailed Description
Referring to fig. 1-3, a preceding suspension control arm assembly structure, including integrative stamping forming's panel beating body 10, panel beating body 10 is provided with preceding bush assembly 20, back bush assembly 30 and bulb round pin assembly connecting portion 40 along the protruding stretching of its face direction, preceding bush assembly 20 include interference fit's preceding sleeve pipe 21 and preceding bush 22, the axial direction of preceding sleeve pipe 21 is parallel with the board length direction of panel beating body 10 and is located the horizontal direction, the inside and outside both sides of preceding sleeve pipe 21 and panel beating body 10 junction all set up the enhancement welding seam. The sheet metal body 10 is changed from a double-layer plate structure in the prior art into a single-layer plate stamping part structure, so that the length of a welding seam is reduced, the cracking problem and the welding defect which are easy to occur in the forming process are reduced, the weight of the whole control arm is reduced, and the light-weight requirement of the whole vehicle is facilitated; meanwhile, the inner side and the outer side of the joint of the metal plate body 10 and the front sleeve 21 are provided with the reinforcing welding seams, the welding seams are high in strength, and the risk of cracks at the joint is avoided.
Specifically, as shown in fig. 4, a flange 11 is downwardly disposed at an edge of the sheet metal body 10, the sheet metal body 10 extends to the upper portion of the front sleeve 21 to form a first connecting portion 12, the flanges 11 at two sides extend to the lower portion of the front sleeve 21 to form a second connecting portion 13, an outer reinforcing weld 14 is disposed on the outer side of the first connecting portion 12 and the outer side of the second connecting portion 13, and an inner reinforcing weld 15 is disposed on the inner side of the second connecting portion 13. In the prior art, the joint of the sheet metal body 10 and the front sleeve 21 is only provided with the outer reinforcing weld seam 14 on the outer side of the first connecting part 12 and the outer side of the second connecting part 13, and the inner reinforcing weld seam 15 is additionally arranged on the inner side of the second connecting part 13, so that the weld seam strength is high.
Although it is better to provide the inner reinforcement welds 15 on the inner sides of the second connection portions 13, the two inner reinforcement welds 15 are provided only on the inner side of one of the two second connection portions 13, depending on process considerations. Because the welding seam strength of the connecting part of the sheet metal body 10 and the front sleeve 21 can be met by only arranging one internal reinforcing welding seam 15, the internal reinforcing welding seams 15 do not need to be arranged on the inner sides of the two second connecting parts 13, the process is simple, and the cost is low.
The face downward punching press of panel beating body 10 has depressed part A, depressed part A extend to bulb round pin assembly connecting portion 40 by back bush assembly 30, depressed part A wholly is the curved arc type, depressed part A's both sides are bellying B, turn-ups 11 set up the edge at bellying B. Direct punching press depressed part A on panel beating body 10, depressed part A and bellying B constitute additional strengthening together, need not set up the strengthening rib in addition, and required mould simple structure, depressed part A extends to bulb round pin assembly connecting portion 40 by back bush assembly 30 simultaneously, and intensity is high.
In order to avoid stress concentration, a process mounting hole 16 is formed in the middle of the recessed portion a, and a plurality of lightening holes 17 are formed in the recessed portion a except the process mounting hole 16.
