Abstract: Apparatus (10) for retaining a joint (12) of an endless track (14) for a crawler-type vehicle which includes a metal preform (64, 66) which is pressed into a retainer cavity (60, 62) surrounding and located at each of the ends of the joint (12) of the track (14). The cavities (60, 62) are cooperatively formed by a pin groove (70) in the opposite end portions (40, 42) of the pin (20) and a link socket (72) in the respective link outboard end portions (26, 27) and which are disposed in registry with the pin grooves (70). Once intruded into the cavities (60, 62), the formed-in-place retainers (64, 66) thereby provided virtually eliminate any end play in the joint (12) during operation of the crawler vehicle.

Abstract: The track assembly comprises a link hinged to connect both ends. Said link comprises a pair of flanges (1, 2) having overlapping portions which are provided with bores for the pin of the link (3, 10). The portions of the flanges abutting each other extend in parallel to the pivoting plane of the flanges, The portions of the flanges (8, 9) are in mesh with each other by toothings of which the teeth (12) and the interdental spaces (13) are arranged in circles centered on the pin of the link. The flanges (1, 2) are connected to a base plate (5). In order to obtain a good, autonomous connection, resisting to traction forces, during the closure of the end link (7), the teeth are provided with a clearance. By means of such clearance, the corresponding portions of the flanges (8, 9) are kept connected in a meshing relationship by the transverse forces generated by the traction forces whereas the base plate (5) is connected to the flanges (8, 9) without being subjected to traction or transverse forces.@00

Abstract: A track section (10) adapted to be linked to a plurality of similar track sections to form a track belt for mounting around the outer periphery of vehicle tyres. The track section comprises a crossbar member (11) and two lateral support members (12). A ground engageable support surface is provided on the outer side (14) of the crossbar member and comprises first and second elongated support surface sections (16, 17) extending in parallel with each other in the longitudinal direction of the crossbar member on opposite sides of a longitudinal centre line of the crossbar member. Each one of these elongated support surface sections (16, 17) is undulated, at least over a major part of its longitudinal extension, so as to form undulated support surface areas (18) with wave crests(19)and wave troughs (20) extending in the cross-direction of the crossbar member.
