Strengthen aluminum forgings, optimizing steel and secondary heat treatment of steel, the overall structural strength is improved by 15% compared with the original in all aspects (mainly shear resistance, tensile, swing fatigue test, pull-off force test, long-term high-intensity test in extreme environments such as saline-alkali mud)
The control arm bushing mainly consists of an inner tube, an outer tube and a middle rubber part, which can be divided into oil-bearing bushing and full rubber bushing; the inner tube of the bushing is made of 6061 material, and the bending ultimate strength is 228 MPa; at the same time, a small amount of zinc is added to improve the strength of the aluminum alloy, and the colloid content of the outer ring is increased by 5% to improve the strength and life of the rubber.
