Abstract

[0002] The drawbar of a full-trailer dump truck is a crucial component connecting the tractor and the dump truck, playing a key role in transmitting traction and supporting the cargo. The integral drawbar of a full-trailer dump truck consists of a welded drawbar body and a traction connection bracket. The drawbar body includes a first side panel, a second side panel, and an upper panel, all welded together as a single unit. This integral drawbar structure eliminates the stress concentration points of segmented welds, ensuring reliability and aesthetic quality, and extending the drawbar's service life.
[0003] Currently, when welding the drawbar of a full-trailer dump truck, the drawbar's shape and the positions of the relevant parts must be marked on a flat plate. The parts are then arranged according to the marked lines and spot welded. After checking the drawing using measuring tools such as a tape measure and a square mandrel, the spot welds are securely secured. This method of welding a full-trailer dump truck drawbar results in low labor efficiency, low welding precision, poor welding consistency, and difficulty controlling welding quality.
