摘要： A continuous track with end connector removal system for removing a pair of end connectors includes a battle tank having a frame and a pair of continuous tracks is rotatably attached to the frame. Each continuous track comprises a plurality of track pads being removably coupled to each other and being positioned successively along each continuous track. A plurality of end connectors removably secures the track pads together and a track extractor assembly pushes a pair of end connectors away from the track pads, wherein the track extractor assembly simultaneously removes the pair of end connectors from the track pads.

摘要： A track pad includes a shoe member that has two bottom voids extending upwardly from the ground engaging surface of the shoe member, and which form a central support pillar having a serpentine surface laterally on side of the central support pillar, and another serpentine surface laterally on the other side of the central support pillar. The two bottom voids form oval perimeters at the ground engaging surface.

摘要： A track link for a ground-engaging track system includes a link body having a pin bore formed in a first link strap and a bushing bore formed in a second link strap. The link body includes, upon an outboard link side, a bore peripheral surface extending circumferentially around a bore center axis, and a guide protrusion including an outer bump surface located outboard of the bore peripheral surface. The pin bore receives a track pin attached by swaging and defines a diametric plane through the bore center axis oriented parallel to an upper rail surface. At least a majority of the outer bump surface is between the diametric plane and the upper rail surface, and an entirety of the outer bump surface may be between the bore center axis and the upper rail surface. The guide protrusion protects material of the track link and/or track pin from wear that can prevent re-swaging.

摘要： A track link plate includes a main body, a first shaft hole, a second shaft hole, two through holes, a supporting rib and a first extending portion. The first shaft hole passes through a first end of the main body. The second shaft hole passes through a second end of the main body. The two through holes are arranged in an interval between the first shaft hole and the second shaft hole. The supporting rib is located between the two through holes. The first extending portion protrudes outward from a second surface of the main body. A distance of the first extending portion from the edge of the through holes to the rotating inner edge is greater than or equal to one third of a total height of the main body. Therefore, the strength of the track link plate can be strengthened.

摘要： A track joint assembly includes a first track chain and a second track chain, and a track pin including a first pin end, a second pin end, and a center section. A track guiding space extends between the first track chain and the second track chain. The center section of the track pin has an enlarged diameter, relative to first and second pin ends, and an outer wear surface exposed to the track guiding space. The outer wear surface may directly contact a rotatable track-engaging element in a ground-engaging track system, such as a sprocket.

摘要： A track chain member includes a shoe member, and a first rail member extending from the shoe member. The first rail member includes a first lug defining a first bore defining a first longitudinal axis and including a first bushing retention shelf disposed in the first bore, as well as a second lug including a second bushing retention shelf disposed in the second bore. A third lug extends in a direction opposite that of the first lug and second lug and is disposed axially between the first lug and the second lug.

摘要： A ground-engaging track includes a track chain formed of standard links and at least one master link. The master link include a first half link and a second half link, clamped together by way of a forward bolt and a rearward bolt. Clamping surfaces of the first half link and the second half link form a first tooth set and a second tooth set, respectively, which may include a total of 2 or 3 full teeth and tooth roots, confined in distribution between a forward bolt hole and a rearward bolt hole.

摘要： A connection assembly for articulated chains which comprise mutually-pivoted links that are split between at least one initial link and at least one terminal link. The assembly comprises transverse holes of the initial link and of the terminal link, which are arranged in mutual alignment when the initial and terminal links are in the coupling configuration; a master pin, with shape and dimensions substantially complementary to those of the holes and adapted to be inserted into those holes in order to couple the initial and terminal links; at least one elastic peg that can be accommodated, with elastic forcing thereof, in at least one respective radial channel which is defined, in its outermost parts, on at least one link chosen from between the initial link and the terminal link and, in its innermost part, on the master pin.

摘要： A track link for a machine track includes an elongate link body having an upper rail surface with an inboard peripheral edge and an outboard peripheral edge each formed upon a first link strap, a second link strap, and a middle section. The upper rail surface defines a longitudinal midline and at least one of the inboard peripheral edge or the outboard peripheral edge upon the first link strap and the second link strap is canted, in an inboard-outboard direction, to a longitudinal midline of the upper rail surface.
