In the crawler machinery, most of the driving wheels are arranged at the rear, which has the advantage of shortening the length of the crawler driving section, reducing the friction loss at the crawler pin caused by the driving force, and prolonging the service life of the crawler. and it is not easy to arch the lower part of the crawler, which avoids the danger of crawler falling off during steering, and is conducive to improving the efficiency of the walking system. The center height of the driving wheel should help to reduce the height of the center of gravity (or car body), increase the grounding length of the track, and improve the adhesion performance, so the height of the driving wheel should be as small as possible.
