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.

主权项

1. A caterpillar track wheel with division of work between track and chain, comprising a flexible chain ring (101), unit tracks (201) for dispersing stress on supporting wheels (401) from ground, axle housings (601), track guide wheels (402), a driving wheel (407) and a track supporting wheel (301), characterized in that said unit tracks (201) are laid on the outer arc of the flexible chain ring (101) and are in point connection with the flexible chain ring (101) in the longitudinal direction, the length of each unit track (201) is set in such a way that two or more longitudinally or slantly arranged supporting wheels (401) can be held above each unit track (201), said supporting wheels (401) are installed on the axle housings (601) and are arranged according to a longitudinal distribution curvature, and the longitudinal curvature of said unit tracks (201) is equal to or smaller than the longitudinal distribution curvature of the supporting wheels (401) arranged on the axle housings (601).
