Description

Technical Field

[0001] The utility model relates to the technical field of semitrailer frames, in particular to a semitrailer frame protection reinforcement structure. Background Art

[0002] The main longitudinal beam is the main load-bearing structure of the semi-trailer frame and is usually welded with high-strength steel.

[0003] The semi-trailer frame is an important component of the semi-trailer. Its design rationality and manufacturing quality directly affect the semi-trailer's carrying capacity, driving stability and service life.

[0004] Unbalanced force on the semi-trailer frame is one of the main reasons for frame deformation, twisting, and fatigue fracture. During driving, the weight and distribution of the cargo carried by the semi-trailer will change, such as the center of gravity of the cargo shifting, the difference in loading and unloading cargo, etc. These factors will cause uneven load distribution on the frame, resulting in additional bending moment and torque.

[0005] When the force on the frame is unbalanced, some areas will bear excessive loads while other areas will bear less loads. This will cause the beams and plates on the frame to bend, twist, and compress, which will cause the overall deformation and distortion of the frame. Long-term unbalanced force will cause fatigue in the frame material and accelerate the occurrence of metal fatigue fracture. Utility Model Content
