Abstract

A damped caterpillar comprising; an elastic and deformable annular spacer means 61 rotatable about a central axis (x) thereof and with opposing radial side portions (66, 67) connected to each other by a generally transverse annular flat peripheral portion (68) with a width that is extends laterally in relation to said lateral portions and in the same direction as said axis and an endless track assembly means (62) completely mounted around said spacer means for joining said spacer means substantially at one with it, said endless track assembly means being characterized by an annular link link assembly (80) including a plurality of links (85, 86, 87, 88, or 85b) pivotally connected to each other about axes that are arranged radially inward from the outer surface (69) of the peripheral portion of said spacer means, located adjacent to each of said side portions and projecting radially inward along said side portions and a plurality of rigid shoes (71) closely positioned circumferentially for ground engagement each being connected to at least one pair of laterally spaced links and with portions (74) of generally transverse flat uninterrupted internal surface held in compressed contact with the outer surface portions of said peripheral portion to circumferentially surround and completely and substantially cover said spacer means to form substantially circumferentially continuous contact therewith and cooperating with said spacer means to form a variable footprint of at least two shoes when they are coupled with a horizontally arranged fixed surface and subjected to a load imposed on said vertically damped caterpillar down in relation to said central axis and said fixed surface to place the inner surface parts of at least two of said shoes as in a substantially coplanar relationship. An annular elastic spacer means having a generally peripherally extending outer peripheral surface and radially rotatable disposed side portions about a central axis thereof and an endless track assembly means in the form of a polygon completely mounted around said spacer means for substantially joining therewith said spacer means, said endless track assembly means being characterized by: two annular sets of articulated endless links positioned along the opposite sides of said spacer means and a plurality of shoes closely positioned circumferentially for ground engagement surrounding said spacer means and having substantially uninterrupted interior surface portions smooth kept in contact under compression with the spacer means substantially and completely across the width of the outer peripheral surface of said spacer means said set of links being connected to said shoes to closely couple them together, each link set including a plurality of links pivotally connected to each other with each pair of links connected with a longitudinal pivot axis, positioned in parallel and extending therein direction which said central axis and further positioned substantially intermediate of each pair of adjacent shoes and radially inward of the outer peripheral surface of said spacer means.
