Track wheel with division of work between track and chain, methods for fitting pitch rails to flexible chain and for buffering pre-stress, and open-close type wheel axle

摘要

The present invention relates to a caterpillar track wheel with division of work between track and chain, methods for fitting unit track with flexible chain ring, methods for buffering prestress, and an open-dose type axle housing. Since a structure that each unit track is separated from a flexible chain ring is adopted, the thickness of the unit tracks does not influence the winding stress of the flexible chain ring and the unit tracks without thickness limitation can effectively disperse stress from the ground to more supporting wheels. Since the thinner flexible chain ring is only responsible for serially connecting the unit tracks and transmitting power, the winding stress and the tension change are reduced.

1. A method for fitting unit track to a flexible chain ring of a caterpillar track wheel with division of work between track and chain, the caterpillar track wheel with division of work between track and chain comprising a flexible chain ring (101) and unit tracks (201), characterized in that raised tenons (102) are arranged on said flexible chain ring (101), and depressed mortises (202) are arranged on said unit tracks (201) and are fit with the raised tenons (102) on the flexible chain ring (101);
wherein the tenons (102) comprise rigid tenon beams (103) disposed therein; one or more unit track screw holes (203) which penetrate through said unit track(201) are formed in the mortise (202) of the unit track (201), and screws penetrate through the unit track screw holes (203) to assist a fixed connection of the unit tracks (201) to the rigid tenon beams (103) embedded in the tenons (102) of the flexible chain ring (101).
