Description
Technical Field
The utility model relates to a control arm especially relates to a triangle-shaped structure lightweight control arm that pipe fitting is constituteed.
Background
The control arm (also called swing arm) is used as a guide and force transmission element of a vehicle suspension system, transmits various forces acting on the wheel to a vehicle body, and simultaneously ensures that the wheel moves according to a certain track. The control arm elastically connects the wheel and the vehicle body through a ball hinge or a bushing respectively. The control arm (including the bushing and ball head associated therewith) should be sufficiently rigid, strong, and have a useful life.
The existing control arm generally adopts a stamping welding technology, and a swing arm body and a bushing sleeve or a ball pin cup seat are welded together, so that the following problems exist:
1. the sheet metal stamping part occupies a large space, and various features are often made on the swing arm body in order to meet the gap requirements of peripheral parts such as a stabilizer bar, a driving shaft, a shock absorber and the like, so that the structure and the process become complicated, and the development period of a die is prolonged;
2. the metal plate stamping part needs to develop a die, so that the cost is increased, the die needs to be maintained and maintained regularly, and if the die is not maintained properly, the problems of poor precision table and quality defects of the swing arm can be caused;
3. the swing arm body is all formed by the sheet metal component welding, adopts the upper and lower plate tailor-welded structure, and the welding seam is many, easily causes welding defect, leads to the swing arm quality overweight simultaneously, can not reach lightweight demand.
