Description

Technical Field

[0001] The utility model relates to the technical field of all-terrain vehicles, in particular to a high-strength agricultural all-terrain vehicle frame. Background Art

[0002] At present, most all-terrain vehicle frames adopt a frame structure, with a large number of welded parts on the frame and a messy layout, resulting in complex welding jigs and welding processes. High professional quality requirements are imposed on welding inspection tools and welding personnel. Moreover, since the current all-terrain vehicles are mostly used for leisure and entertainment, although they have strong off-road and climbing capabilities, their own load-bearing capacity is weak and the endurance time is short, and they cannot meet the high-load environment operations such as field short-distance transportation, agricultural transportation, and construction site transportation.

[0003] Therefore, those skilled in the art are committed to developing an agricultural all-terrain vehicle (FATV) frame that reduces the frame complexity, improves the frame strength, improves the frame welding process, and reduces the complexity of the frame welding jig.
