Description

Technical Field

[0001] The utility model relates to the technical field of AGV transport vehicles, in particular to a driving wheel and an AGV transport vehicle thereof. Background Art

[0002] Logistics AGVs are widely used in the market. Compared with traditional gasoline trailer truck transfer methods, they have the advantages of low maintenance costs, easy unmanned operation, and full automation. AGVs, or unmanned guided vehicles, are transport vehicles equipped with automatic guided vehicles (AGVs) that can travel along a prescribed path, while also possessing safety features and various moving and loading functions. In actual applications, they require no human operator and can operate fully automatically. Power can be supplied by batteries or fuel, and their route and behavior are generally controlled by a computer. AGVs primarily follow signals such as electronic signals from electromagnetic tracks to move or execute the next action. For example, wheeled mobile robots offer advantages such as greater mobility, higher efficiency, and a simpler structure compared to walking, crawling, or other non-wheeled mobile robots. Compared to other equipment commonly used in material transportation, AGVs require no fixed installations such as tracks or supports, and are therefore unrestricted by site, roads, and space. Therefore, in automated production and processing scenarios, they can best demonstrate their automation and achieve efficient, unmanned production. While most current AGVs have strong handling and transport capabilities, they often struggle to ensure stable discharge of stacked profiles, necessitating batch transport, which can negatively impact handling efficiency.
