Abstract: A machine tread including a first and second pair of plates. The plates have corresponding first ends and second ends, and the second ends of the first pair include outer bores. The first ends of the second pair include aligned bushing bores. The first ends of the second pair fit between the second ends of the first pair, aligning the outer and bushing bores. Ends of a bushing including an inner bore engage the bushing bores forming a pin bore through the inner and outer bores. A retention pin fits in the segmented pin bore. A head end abuts an external surface of the first pair of plates and a locking end extends past the pin bore. A retention cap engages the locking end. A dowel pin fits through a dowel pin bore in the retention cap and the locking end to limit movement of the retention pin.

Abstract: A device for connecting two free ends of a rubber band track to one another or for connecting the ends of several band segments to one another. The device has two or more tubes and a pin rubber-mounted in the respective tube. The tubes are in each case inserted into the one end and into the other end of the rubber band track or of the band segments, and at least one connector, by way of which the pins are coupled together in a rotationally fixed manner. The rotational rigidity of the pins in relation to their respective tube, brought about by the rubber mounting, is adjusted in dependence on the flexural strength of the rubber band track or of the band segments in the region of the ends.

Abstract: In the operation of track-type machines, the pin and bushing assemblies incorporated in the track assemblies are typically lubricated to accommodate wear that occurs as they rotate relative to one another. Since the relative rotation occurs over a relatively small area, there are instances wherein portions of the interface between the pin and bushing never are exposed to the lubricating fluid, thus causing premature wear. The present invention provides a track assembly that has a track bushing that defines a bore that is defined by a plurality of wall segments. The wall segments join one another to define a plurality of cusps that form axially extending channels that extend the axial length of the bushing. The channels maintain a quantity of lubricant during relative rotation of the track pin and bushing to prevent premature wear.

Abstract: In hinge tracks with rubber mountings (5) in which rubber-lined tubular steel bushes mount track pivot pins (20), the pin ends are usually provided with screwthreaded projection portions so that the steel bushes (10) are motion-free braced relative to each other and relative to the track pivot pins (20) by means of nuts. In order to improve the useful life of the rubber mounting (5) and reduce maintenance, a rubber-lined spreadable bush (10) with at least one dividing gap (11) is proposed instead of the tubular bush. The internal width (25) of the bush (10) which is pressed into position is less than the diameter (27) of the track pivot pin (20). The inserted track pivot pin (20) expands the bush (10) which is pressed into the chain link member (1). In that case the track pivot pin (20) is braced in the bush (10) and is fixed in its longitudinal direction by frictional engagement and in the peripheral direction by frictional engagement and/or positively locking engagement.

Abstract: The invention is a double pin track unit comprising a track body, two bores extending transversely through the body, a track pin within each bore extending the length of each bore, links keyed to the pins and extending radially from the bores, sleeves keyed to the pins for separating the links, and elastomeric sleeves in the torroidal space between the outer diameter of the pin and the inner diameter of the bore.

Abstract: An improved bush assembly for insertion into an aperture of a lug of a track part of a tracked vehicle is disclosed. An exposed outermost side wall of the bush has an extended surface length, so that when under design precompression the wall makes angles of approximately 90.degree. with the inner surface of the aperture and 70.degree.-80.degree. with the outer surface of the central pin. The wall may be concave and the bush may comprise a number of annular bush parts. The high tensile strains which develop on that wall of the bush are thereby minimized and bulging out of the bush beyond the end of the pin is discouraged.

Abstract: An arrangement forming an assembling aid on crawler chains for track-laying or crawler track vehicles, whose chain link members are equipped with rubber-cushioned coupled pins, and which are interconnected through the intermediary of clamp-like connectors slideable over the ends of the coupling pins and adapted to be fixedly anchored by means of a screw. The coupling pins which are to be interconnected in the assembled condition are provided with securing elements which engage into a slot formed in the connector. Each individual coupling pin is equipped with separate adjusting or setting elements, which protrude cog-like beyond the cross-section of the coupling pin, wherein the adjusting elements evidence a lower height or diameter relative to the width of the slot in the clamped-in condition of the connector, and wherein guide surfaces are formed on the connector for the preadjustment and final adjustment of the adjusting elements.

Abstract: An elastomeric bushing especially useful in the construction of track-type vehicles. Track links of such vehicles are formed with circular openings and joined by octagonal link pins. A metal pin sleeve having an octagonally shaped internal opening slides onto the pin. The pin sleeve is formed with an elliptical cross sectional shape. An elastomeric bushing having an elliptical shape is bonded to the elliptical metal sleeve with their major axes at right angles to each other. The bushing is forced into the circular opening in the track link so that the elastomeric bushing is under compression.

Abstract: A modular track for a tracked vehicle is described. The track includes a plurality of traction elements, each made of a resilient material. Each element is shaped to define tapered ends and a lower ground-engaging surface having radiused surface portions on which the element can pivot in use.

Abstract: A track construction, provided for tracked vehicles such as tanks, comprises alternate track members and connection members which are connected together by transversely extending connecting pins. The track members each comprise first and second spaced, parallel sets of transversely extending tubular members connected together by a bridging element, the tubular members of each set being axially aligned and spaced apart laterally to form gaps therebetween. The connection members each include a wheel contacting surface, and ground contacting pads are mounted thereto on the opposite side thereof from said wheel contacting surface. The track members also each include a wheel contacting surface and preferably include ground contacting pads or the like, the ground contacting pads of the track members and the connection members being arranged in a longitudinally staggered relationship, intersecting beneath the connecting pins.

Abstract: An endless track for a tracked vehicle is described. The track includes guiding elements pivotally coupled with other track elements. Each guiding element defines lateral guiding surfaces, a lower ground-engaging surface and lateral track driving projections.

Abstract: An endless track for a tracked vehicle is described. The track is of modular form and includes traction elements and track guiding elements. The elements are arranged in rows and are positioned symmetrically with respect to the longitudinal median line of the track, whereby the track is loaded symmetrically in use.
