The invention provides a double-wheel differential driving wheel which comprises a motor and support assembly, a single-side driving wheel assembly and a single-side follow-up wheel assembly. The single-side driving wheel assembly and the single-side follow-up wheel assembly are symmetrically arranged on two sides of the motor and support assembly and are matched with the motor and support assembly in use, the motor and support assembly are connected with a speed reducing box assembly, and the speed reducing box assembly is correspondingly matched with the single-side driving wheel assembly in use. A single-side driving wheel and a single-side follow-up wheel are installed on two sides of the motor and support assembly respectively, so that a driving wheel has two wheels to bear load simultaneously, and the bearing capability of the driving wheel is improved. The single-side driving wheel and the single-side follow-up wheel are located on two sides of the center of a driving wheel turntable assembly, the two wheels can change sliding friction with the ground during steering of a single wheel into rolling friction between two wheels and the ground through differential rotation during steering, tire abrasion is reduced, and the power required by the steering motor is reduced.
Description
technical field [0001] The present invention relates to a power drive device, in particular to an electric drive device for a mobile robot and an AGV, specifically, it shows a two-wheel differential drive wheel. Background technique [0002] AGV belongs to the category of wheeled mobile robots. It is the abbreviation of (Automated Guided Vehicle), which means "automatically guided transport vehicle". , a transport vehicle with safety protection and various transfer functions must constantly change its direction independently during the driving process. [0003] In some AGV products, driving wheels are required to realize multi-directional driving and braking of the vehicle. With the continuous development of AGV, more and more requirements are put forward for the driving wheel, such as the size, function and load capacity of the product. The structure and capacity of the existing products cannot meet the needs of the market. [0004] Therefore, it is necessary to provide a...
