ABSTRACT:
Each track shoe in a link-shoe assembly built in a track chain for a track-type vehicle is lined with an elastomer pad. One elastomer pad in one track shoe abuts another adjacent elastomer pad in compression in a manner that when adjacent track links effect a relative pivotal movement, the adjacent elastomer pads are further compressed together and produce an elastic resistance for track links, thereby eliminating a sag in a track chain.
Preferably, each elastomer pad is secured to each track shoe through the medium of a plate spring. The size of the elastomer pad is so selected that adjacent pads are compressed together, when assembled.
Alternatively, adjacent corners of elastomer pads may be rounded so as to provide a smooth contact therebetween, when the adjacent track links effect a relative pivotal movement, or may be covered with extended portions of the plate spring to reduce wear of the elastomer pads.
