Adaptive triangular track sprocket of the present invention: 1. Through the two main drive wheels and a plurality of auxiliary drive wheels, it can move elastically in the vertical and horizontal directions. When an obstacle appears, the main drive wheels hit the obstacle first and are compressed. Since the main drive wheel can move elastically in the horizontal direction, the horizontal reaction force generated by the extrusion pushes the

main drive wheel, making it easier for the main drive wheel to overcome the obstacle. At the same time, the main drive wheel can also move elastically in vertical

direction. When the obstacle is already below the main drive wheel, the obstacle will compress the main drive wheel in the vertical direction. At this time, the vertical reaction force generated by the extrusion will press the main drive wheel, so that the main drive wheel moves stably on the obstacle and will not be damaged. The same is true for the auxiliary drive wheel when it encounters an obstacle. 2. By connecting the crawler to the active wheel and winding around the outside of the two main drive wheels and the plurality of auxiliary drive wheels, the

The track is set in motion by the rotation of the active wheel, which in turn sets the two main drive wheels and the multitude of auxiliary drive wheels in rotation. The multitude of auxiliary drive wheels are located between the two

main drive wheels, which helps keep the movement of the track stable when it is between the two main drive wheels.
