Abstract:
An undercarriage assembly (116) for a mobile machine (100) includes a continuous track (120) having a plurality of mated track links (122) that can translate with respect to the machine (100). Each track link (122) may include a shoe portion (150) and a body portion (160). The body portion (160) includes a plurality of projecting pin lugs (160) each having a pin bore (168) to receive a pin and link adjacent track links (122) together. The pin lugs (160) can include a pair of sprocket lugs (190) for making rolling contact with a sprocket (142), a pair of roller lugs (200) for making rolling contact with a plurality of rollers (140), and a side lug (210) having a protruding shoulder (212) to assist in aligning the plurality of rollers (140).
Abstract:
A track link (26) having a wear sensing device (32) is disclosed. The track link may include a link body (60) including a surface (64), a cavity (80), and at least one hole (50, 52) configured to receive a track pin (40). The track link may further include the wear sensing device positioned in the cavity. The wear sensing device may be configured to generate a signal indicative of a wear parameter of the surface. The track link may further include a containment mechanism (84) configured to secure the wear sensing device in position inside the cavity.
Abstract:
Disclosed are various exemplary embodiments of a track joint assembly. In one exemplary embodiment, the track joint assembly may include a first link having a first bore. The track joint assembly may also include a second link having a second bore including first and second portions. The first and second portions may have different diameters. In addition, the track joint assembly may include a solid pin positioned at least partially within the first bore. The track joint may also include a bushing positioned coaxially around the pin. The bushing may include an axial end portion disposed in and contacting the first portion of the second bore. The bushing may also include an axial end-adjacent portion disposed in and contacting the second portion of the second bore. An outer diameter of the end-adjacent portion may be larger than an outer diameter of the end portion.
Abstract:
Disclosed are various exemplary embodiments of a thrust ring for a track joint assembly. In one exemplary embodiment, the thrust ring may include a generally cylindrical outer surface. The thrust ring may also include a generally cylindrical inner surface including at least one protrusion extending toward a central axis of the thrust ring.
Abstract:
A track link (50, 52) has a link body. The link body of the track link may include a first substantially planar side surface (90), a second substantially planar side surface (92) opposite the first substantially planar side surface, a shoe face (98) extending between the first and second substantially planar side surfaces, and a roller rail (96) extending between the first and second substantially planar side surfaces opposite the shoe face.
Abstract:
A track link (24) for a ground-engaging track (16) includes an elongate link body (24) having a lower hardness material (34) forming a lower mounting surface (26) for mounting a track shoe (28), and a sacrificial higher hardness material (36) forming an upper rail surface (30) for contacting rotatable track engaging elements (11, 15). The lower hardness and higher hardness materials (34, 36) transition at a material interface (38) within the elongate link body (24), and the material interface (38) is longitudinally non-uniform, such that the sacrificial higher hardness material (36) has a varying depth from the upper rail surface (30) to retard scalloping.
Abstract:
A ground-engaging track system (14) for a machine (10) includes a track (22) extending about a rotatable track engaging element (16), and having a track chain (24) with a plurality of elongate links (30) each including an upper rail surface (42) formed of a sacrificial wear material and having a convex longitudinal profile configured to delay scallop formation therein. A link (30) for a track chain (24) and related methodology are also disclosed.
Abstract:
Die Erfindung betrifft eine Gleitschutzkette (1), insbesondere für forst- und landwirtschaftliche Fahrzeuge. Die Gleitschutzkette (1) soll eine hohe Traktion bei geringem Gewicht und leichter Montierbarkeit ermöglichen. Gleichzeitig soll sie den Fahrbetrieb auch auf Strassen erlauben. Um dies zu ermöglichen, ist erfindungsgemäß eine Gleitschutzkette zur Anbringung an zwei hintereinander abstandsunveränderlich angebrachten Rädern mit Reifen (2), insbesondere für die beiden Räder einer Tandemachse, vorgesehen. Die Gleitschutzkette (1) weit zwei seitliche, seitenstabile Führungsketten (4) auf, die im montierten Zustand seitlich der Lauffläche (12) der Reifen (2) liegen. Zwischen den beiden Führungsketten (4) erstreckt sich ein Laufnetz (14) mit Kettensträngen (15). Bevorzugt ist das Laufnetz in Leiterabschnitte (16) unterteilt, die nur über die Führungskette (4) miteinander verbunden sind. Gelenkstellen (9) der Führungsketten liegen in einer radialen Position zwischen dem Radius der Reifenschulter (12) und der Reifenmitte (13). Die Führungsketten (4) sind insbesondere als Laschenketten ausgebildet.
