    摘要： 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.

    摘要： Disclosed is a lower track for mounting rubber pads on a track shoe to be attachable and detachable after assembling a steel plate which is adhered with divisionally formed rubber pads as a single unit without additionally perforating coupling through-holes in the track shoe when the rubber pad which forms the lower track and the track shoe which is formed of a metal material are coupled. The lower track of a crawler excavator according to the present invention comprises: first and second rubber pads which are divisionally formed; a first steel plate which supports the bottom surface of the first rubber pad by surrounding the same, and has first hooks formed on the bottom surface thereof and coupling holes formed in a connection stepped-portion, which is formed at the opposite side of the first hooks; a second steel plate which supports the bottom surface of the second rubber pad by surrounding the same, and has second hooks formed on the bottom surface thereof, connection protrusions formed at the opposite side of the second hooks so as to be secured on the connection stepped-portion, and connection through-holes formed in the protrusions so as to correspond to the coupling holes; and coupling members sequentially passing through the through-holes formed in the second rubber pad and the through-holes formed in the second steel plate so as to be fixed in the coupling holes of the first steel plate.

    摘要： A cross-link for a track of a tracked vehicle, such as a tracked carrier vehicle. The track comprises a plurality of belts spaced apart to accommodate a plurality of wheels of the tracked vehicle, the belts having a ground-facing side for facing the ground. The cross-link comprises an elongate member for mounting to the belts to interconnect the belts. The elongate member has a belt-engaging face contacting the belts on the ground-facing side when the elongate member is mounted to the belts. The cross-link also comprises a sole mountable to the elongate member. The sole comprises a ground- engaging portion for engaging the ground. A ground contact area of the sole may be substantially different from a projected area of the elongate member onto the ground. For example, a length of the ground-engaging portion of the sole may be substantially different from a length of the elongate member.

    摘要： A master link (62, 64) for a chain assembly (22) is provided. The master link includes a body member (66) with a first side (68), a second side (70) positioned opposite the first side, a shoe surface (76) configured to receive a track shoe (24), and a rail surface (78) positioned opposite the shoe surface. The master link also includes first and second apertures (72, 74) extending through the body member from the first side to the second side and third and fourth apertures (80, 82) extending through the body member from the first side to the second side and located between the first and second apertures. The master link also includes a strut member (84) dividing the third and fourth apertures. The master link also includes a first gap (90) located in the body member and extending from the first aperture to the third aperture and a second gap (92) located in the body member and extending from the fourth aperture to the second aperture. The master link further includes a third gap (94) located in the strut member and extending from the third aperture to the fourth aperture.

    摘要： Es wird eine Traktionskette (2) für eine Raupenkette (1) eines Kettenfahrzeugs, insbesondere eines Pistenfahrzeugs und/oder eines Loipenpräparationsfahrzeugs vorgestellt. Die Traktionskette ist mit Eingriffen (11) für ein Antriebsrad, mit Spurführungselementen (12), die zur Führung eines Fahrwerks des Kettenfahrzeugs in einer in Laufrichtung der Traktionskette (2) verlaufenden Spur (13) an einer Innenseite (2a) der Traktionskette (2) vorgesehen sind, und mit einer Vielzahl von Anbringeinrichtungen (15, 15c, 15d, 15e) ausgestattet, von denen jede zur Anbringung eines Raupenstegs (6, 7) an einer Außenseite (2b) der Traktionskette (2) und quer zur Laufrichtung der Traktionskette (2) vorgesehen sind. Dabei ist die Traktionskette (2) zur Verwendung mit einer parallel mitlaufenden Seitenkette (3, 4, 5) vorgesehen, wobei des Weiteren die Traktionskette (2) teilweise aus einem elastischen, insbesondere elastomeren Grundmaterial geformt ist, in das wenigstens ein Zugmittel (16) in eine Laufrichtung der Traktionskette (2) verlaufend eingebettet ist. Eine wesentliche Eigenschaft der erfindungsgemäßen Traktionskette (2) liegt darin, dass das Zugmittel (16) innerhalb eines Bereichs des elastischen Grundmaterials eingebettet ist, in dessen Umgebung das Grundmaterial zwischen der Innenseite (2a) und der Außenseite (2b) der Traktionskette (2) eine Dicke von wenigstens zehn Millimeter aufweist, dass die Anbringeinrichtungen (15, 15c, 15d, 15e) im elastischen Grundmaterial der Traktionskette (2) eingebettet sind, und dass jede Anbringeinrichtung (15, 15c, 15d, 15e) ein U-förmiges, quer zur Laufrichtung im Wesentlichen durchgehendes und nach außen offenes Aufnahmeprofil (15c, 15d, 15e) aufweist, in das jeweils einer der Raupenstege (6, 7) quer zur Laufrichtung der Traktionskette (2) für eine Anbringung seitlich einschiebbar ist, wobei der Raupensteg (6, 7) an der Anbringeinrichtung (15, 15c, 15d, 15e) in wenigstens einer eingeschobenen Position fixierbar ist.
