Abstract
An endless track (52) for a track laying vehicle has a construction that facilitates replacement and repair of track components as well as providing an extended lifetime of use as compared to conventional vehicle tracks. The components of the track which facilitate its construction and maintenance include a track shoe (60), a replaceable road pad (62) for the track shoe (60), a pin assembly (64) for connecting laterally aligned pairs of the track shoes (60), a hollow pin (66) of the pin assembly (64), a center guide (68) that guides the track on the associated vehicle roadwheels, an end connector (72) that connects ends of the pins (66) associated with adjacent shoe assemblies (70), and a center connector (74) that cooperates with the end connectors (72) in connecting the shoe assemblies (70).
