AI Technical Summary
Due to the complex structure and poor welding consistency of existing commercial vehicles, the soft axle gear shift brackets have large weight and are prone to problems such as poor concentricity and shift jamming during shifting operations.
Made of cast aluminum, the structural connection is strengthened on the arc transition section by setting weight reduction holes, installation holes and reinforcement ribs, and the cast aluminum die-casting process is adopted to improve the consistency and reliability of the overall structure.
It effectively solves the problems of poor concentricity and gear shift stagnation after assembly caused by welding deformation, realizes lightweight weight reduction and reliability improvement of the structure, and ensures the stability of gear shift operation.
