AI Technical Summary
The existing side protection devices of heavy truck chassis have weld defects that lead to a high failure rate and make it difficult to ensure product consistency and reliability.
A split-structure side protection assembly was designed, including a base, a connecting bracket, and a protective plate. The base has a U-shaped groove structure, and the cantilever section is inserted into the base and fixedly connected by a connecting plate. It is made of high-quality carbon steel and low-alloy carbon steel materials, and is fixed by welding and bolting components to form a frame structure.
It improves the strength and reliability of the bracket, reduces the failure rate, ensures product consistency, facilitates processing, manufacturing and replacement, and saves packaging and logistics costs.
