Strengthen aluminum forgings, optimizing steel and secondary heat treatment of steel, the overall structural strength is improved by 15% compared with the original product 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)
Ball joint: The balljoint steel is national standard 40CR, which has the best comprehensive mechanical properties; the hardenability of this steel is higher than 45 steel (a high-quality carbon structural steel) and is suitable for high-frequency quenching, flame quenching and other surface hardening treatments.
Rubber: CR (chloroprene rubber) has good durability, excellent flame resistance, light resistance, ozone resistance and atmospheric aging resistance; good medium resistance, good oil resistance, water resistance, alkali resistance, acid resistance and solvent resistance.
6082 aluminum, hot forming, forging, high requirements for molds, five-step forging, six-step forging.
The 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, the ultimate tensile strength of 6061 is above 205MPa, the compressive yield strength is 55.2 MPa, the elastic modulus is 68.9 GPa, 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.
The outer tube is zinc-nickel alloy.
High temperature grease: We use Castrol imported grease, and according to its product performance requirements, add a variety of special additives to improve the product quality. The working temperature is from -40℃ to 180℃, and it has good compatibility with POM. The excellent resistance to oil ensures long-term lubrication of plastic parts. At the same time, the low oil separation will not contaminate parts outside the application area.
