<p>A resiliently flexible endless articulated track member (12) for a vehicle includes a series of transverse track elements (40, 140) held in abutting relationship under compression by a plurality of tensile core elements (41) under tension. The said track elements (40, 140) are of taper section defined by taper sides (46.2, 46.3; 146.2, 146.3) which converge inwardly of the tensile core element (41) to permit resilient flexing of the track member (12) around a drive or guide wheel (14, 16). Adjacent transverse track elements (12) have pressure faces (46.2, 46.3; 146.2, 146.3) disposed outwardly of the tensile core element (41), the said pressure faces being adapted in use to abut against each other, to limit reverse bending of the track member (12) under load. The tensile core elements (41) are in the form of endless steel wire ropes, accommodated in seats defined by resilient seat members. The track elements are made up of inner and outer parts. Clamp means are provided to clamp the inner and outer parts and their resilient seat members together, around the tensile core elements.</p> |
