A multi-material track pad for a continuous track assembly is disclosed. The track pad may include a body with a ground-engaging surface, wherein the body is formed of a metal material with a first hardness; a roller-engaging surface, wherein the roller-engaging surface is formed of a ceramic material with a second hardness that is greater than the first hardness; and a sprocket-engaging surface formed of the ceramic material.

A track shoe assembly is described that comprises a drive lug part and a track shoe body including a drive lug cavity configured to receive the drive lug part. The drive lug part has at least one lug portion protruding in a first direction, and at least one 5 supporting protrusion extending in a direction substantially opposite to the first direction. The at least one supporting protrusion is configured to be receivable in a drive lug cavity formed in a track shoe such that a load applied to the drive lug part is at least partially transferred to the track shoe.

Provided is an elastic crawler and an elastic crawler device capable of achieving both low fuel consumption and excellent ride comfort. The elastic crawler comprises: a main body; cores respectively having a pair of wings and being embedded in a circumferential direction; a track roller rolling surface formed on an inner circumferential surface of the main body; a recess formed on the inner circumferential surface in a manner extending from the track roller rolling surface toward a widthwise outer side; lugs formed on an outer circumferential surface of the main body, the lugs respectively extending in a width direction between the cores from one end overlapping the track roller rolling surface in a thickness direction toward the other end overlapping a part in which the wings of the cores are embedded in the thickness direction. The elastic crawler device comprises the elastic crawler, a sprocket and a track roller.

A track chain member according to an embodiment of the present disclosure comprises a first rib coupling the shoe member to the first lug; and a second rib coupling the shoe member to the second lug, defining a first side recess between the first rib and the second rib, the first side recess also extending from the exterior of the shoe member and underneath the first top surface, the first lateral end defining a first lateral end width along the track chain traveling direction, the first side recess also spanning the majority of the first lateral end width along the track chain traveling direction.

A track chain member comprises a shoe member defining a track chain traveling direction and a lateral direction perpendicular to the track chain traveling direction, the shoe member further defining a first lateral end, a second lateral end, and a ground engaging surface spanning from the first lateral end to the second lateral end; wherein the shoe member further defines a main central void disposed on the ground engaging surface that is centered along the lateral direction of the shoe member with respect to the first and the second lateral ends.

Vehicle comprising a hull and motorised aquatic propulsion members and motorised land propulsion members, this vehicle being able to move between a navigation position and a land transport position in which it rests on sets of caterpillar tracks. Each set of caterpillar tracks (1) is equipped with an even number of rollers (7) so as to define a set of adjacent roller pairs (71, 72). The rollers (71, 72) of each pair are connected to the chassis (2) by suspension means comprising a set (12) of at least two superposed curved elastic leaves made of a fibre-reinforced thermosetting resin, namely an upper leaf (131) and a lower leaf (132), the set being fixed on the one hand to the axles (9) of the rollers (71, 72) at its respective ends and, on the other hand, to the chassis (2) in its central part, and the upper leaf (13i) and the lower leaf (132) of each of the sets of leaves (12) are joined together and covered with a layer of elastomer (14).

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.

A wear resistant component includes a matrix portion made of metal, a core embedded in the matrix portion and having a hardness higher than that of the matrix portion, and a plurality of support members having at least one end exposed from a surface of the matrix portion, extending toward an interior of the matrix portion, and contacting the core at a portion other than the one end to define a position of the core within the matrix portion.

An endless track assembly formed from interconnected links pivotally interconnected by a track pin having a wear sleeve. A track bushing formed from high strength steel is positioned over the wear bushing of the track pin and has an inner sleeve formed from composite bearing material either pressed in or bonded to its inner diameter. The internal diameter of the track bushing is sized so that rotation relative to the track pin surface is permitted when the track bushing is engaged by the teeth of a drive sprocket.

An endless-track type mobile climbing vehicle containing a suspension apparatus, transducer manipulator and surface cleaning system to perform non-destructive examination of structures while traversing the structure in all positions. The invention is able to conform to large range of irregularities of the climbing surface while maintaining contact between the track and adhering members and uniformly distributing the climbing loads on the adhering members giving the system a high payload to weight ratio. The invention is moves the inspection transducer over the surface while maintaining correct alignment of the tool relative to the surface. The invention allows an operator to perform an inspection on structures that require cleaning or other preparation prior to inspection. The invention allows an operator to perform an inspection remotely.
