A metal and rubber combined type wear-resisting crawler belt comprises a crawler belt body, wherein, a metal framework is arranged in the crawler belt body, the metal framework comprises a crawler belt support face and a crawler tooth driving face, a wear-resisting platform is arranged at the bottom of the crawler tooth driving face, all areas, except for the wear-resisting platform, of the metal framework are wrapped inside a rubber layer, rubber teeth are arranged on the rubber layer, and the rubber teeth which are located at the position of the wear-resisting platform protrude downward to form a rubber boss; driving teeth are arranged on an outer surface layer of the crawler belt body, and meanwhile an inner surface layer of the crawler belt body is provided with driving grooves and limiting teeth; in addition, the crawler belt support face and the crawler tooth driving face of the metal framework are connected through metal frame supports. According to the metal and rubber combined type wear-resisting crawler belt, a variable cross-section structure is adopted, when a crawler vehicle is driven on a hard surface ground, under the action that the rubber boss and the wear-resisting platform are in contact with the ground simultaneously, the ground contact areas of the driving teeth are reduced, and it is facilitated to lower the abrasion of the crawler belt and reduce diversion resisting moment; when the crawler vehicle conducts field operation, the driving teeth are all in contact with the ground, so that it is facilitated to improve the driving capability of the crawler belt.
