Among them, the toothed belt shaft 102 can mesh with the tooth grooves inside the crawler, so that power transmission can be achieved, and at the same time, slippage between the hub and the crawler can be avoided. On both sides of the toothed belt shaft 102, the outer rim 101 structure is adopted. The outer rim 101 is made of solid rubber. The outer rim 101 also fits with the crawler, increasing the contact area between the hub and the crawler, and can play a certain supporting role.
