Abstract
An articulated endless track for a mobile machine has a plurality of crawler pads connected in series. Each adjacent pair of pads has spaced apart hinge knuckles engaged in alternating fashion to form a hinge pin chamber. Each chamber contains a hinge pin positioned between a pair of retention elements. Each retention element is secured to its associated encircling hinge knuckle. This arrangement protects the retention elements against abrasion while permitting assembly or disassembly of the track to be accomplished readily.
