The driving wheel is composed of a walking motor, a walking deceleration mechanism and a sprocket . The hydraulic pressure from the autonomous pump can be rotated by the walking motor and decelerated by the walking deceleration mechanism.. Then the crawler chain rail is driven by the sprocket installed on the shell to realize the excavator’s walking. A chain hub sprocket is a special-shaped wheel with teeth or gears that engages with a chain, track, or other perforated or dented material. The sprocket is located at the front and rear of the vehicle to drive the rails.
