AI Technical Summary
The existing air spring connection structure in commercial vehicle chassis suspension is heavy, the production process is complex and the cost is high, making it difficult to achieve lightweighting and cost control.
A cover plate is installed on one end of the air spring body, and a mounting platform is installed on the cover plate. A first connecting plate is connected to the mounting platform, and a second connecting plate is bent relative to the first connecting plate to form an L-shaped connecting bracket, which simplifies the production process and reduces assembly time.
The manufacturing process of air spring assemblies has been simplified, reducing weight and cost while improving reliability and stability.
