Using the technical solution of the utility model, compared with prior art steel alloy sheet material stamping parts, trailing arm body uses
Aluminium forging part is made, and forge piece interior solid, even tissue, internal pore-free, aluminium forging part material is lighter, meets Hyundai Motor
Requirement to mitigating the overall weight of automobile, solid forging part is finer and close than the interior tissue of steel alloy sheet material stamping parts, simultaneously
The processing of forge piece is more accurate, ensures the function of part, aluminium forging part components interior dense structure, have passed through T6 heat treatments again,
The performances such as intensity are more excellent, and the service life of part is longer；The folding part of trailing arm body is with being connected away from connecting bottom board one side
The matrix face of the avoiding structure of members fits, avoid automobile vibration from causing damage of the friction between part to part, ensure that
The service life of part, it is ensured that the safety that automobile uses, connecting pole and connection through hole reasonable setting, both ensure that part it
Between connection, in turn ensure that the stress of part, ensure that the service life of part.
Below with reference to drawings and examples, the utility model is described in detail.
