A swing arm bracket and its production method

Abstract

The invention discloses a swing arm bracket and a production method thereof. The swing arm bracket is composed of the following components in percentage by mass: 2.2-2.4% of C, 1.6-1.8% of Si, 0.2-0.4% of Mn, 1.4-1.6% of Al, 1.6-1.8% of Cr, 0.2-0.4% of Cu, 1.2-1.4% of Ba, 1.4-1.6% of V, less than or equal to 0.08% of P, less than or equal to 0.08% of S and the balance of Fe. By reasonably changing the proportion of the components of the swing arm bracket and by providing a reasonable production method, a finished product is relatively high in toughness, wearing resistance and high in strength, the overall weight is reduced, and the cost is lowered.

Description

technical field [0001] The invention relates to the technical field of automobile swing arm brackets, in particular to a swing arm bracket and a production method thereof. Background technique [0002] The vehicle swing arm is an important part of the automobile suspension system. From the structural analysis of the automobile suspension, it is also a complex and odd shape with high technical content and difficult manufacturing technology. It is safe and reliable under the impact of millions of large loads. Auto parts with physical strength, bending deformation, shock resistance and wear resistance when meeting 100% requirements. The existing swing arm bracket still has the disadvantages of strong strength, insufficient toughness, insufficient wear resistance, unreasonable production method and the like. Contents of the invention [0003] In view of the above problems, the present invention provides a swing arm bracket and a production method thereof, which have the advan...
