Abstract

The invention relates to a control arm assembly with a turned edge sleeve structure and a manufacturing technology for the control arm assembly. The control arm assembly comprises a control arm main body, reinforcing folded edges, a bush hole, a bush sleeve and an excircle turned edge, wherein the reinforcing folded edges are positioned on two sides of the control arm main body; the bush hole is positioned in a near end of the control arm; the excircle turned edge is positioned between the bush hole and an end of the control arm main body; the excircle turned edge and the reinforcing folded edge are integrated; and the bush sleeve penetrates in the bush hole. By the control arm assembly in the technical scheme, the problems that technological materials of an inner turned edge of the existing bush is thinned, and the turned edge cracks are solved; and moreover, by a sleeve structure, the connection rigidity of the bush is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of automobile suspension systems, and in particular relates to a control arm assembly with a flanged sleeve structure and a preparation process thereof. Background technique [0002] The function of the control arm assembly and its fixing mechanism in the independent suspension structure of the automobile chassis is to coordinate the roll moment generated during the beating process of the left and right suspensions, so as to realize the operational stability of the chassis. [0003] Such as figure 1 Shown is the structure of the control arm assembly in the prior art, including a control arm 11 , an external reinforcement flange 12 , a flange plane 13 and a bush flange 14 . The molding method of the control arm assembly is: [0004] Blanking: Trim the edge of the flat sheet according to the outline of the control arm to form a preformed sheet; [0005] Forming hem: use the forming mold to shape the control...
