RUBBER TRACK AND TRACK ROLLER FOR CRAWLER

PURPOSE: A rubber track and a track roller for a crawler are provided to prevent displacement of the rubber track from the track roller in traveling on the uneven road or suddenly turning by modifying the shape of the projection part of the core bar inserted to the rubber track and the shape of the blade part of the track roller. CONSTITUTION: A rubber track and a track roller(20) are installed in a crawler, and a core bar(15) is inserted to the rubber track. Both projection parts(17) are formed on the core bar of the rubber track, and both blade parts(22) are formed in the track roller. Left and right vertical surfaces are formed perpendicularly to the core bar, and the right-angled inner vertical surfaces are formed in the blade parts of the track roller. The blade part of the track roller is combined with the projection part of the core bar of the rubber track to prevent the rubber track from being separated from the track roller during traveling on the uneven road or suddenly turning.
