A track component for use with a track assembly includes a gyro sensor that monitors a track wrap angle of the track chain assembly about the idler wheel, or the drive sprocket.

A pin retention device comprises a fastener defining a longitudinal axis, a first end and a second end along the longitudinal axis, a head at the first end and a threaded portion at the second end, a tubular spacer defining a thru-hole configured to receive the fastener, and a nut defining a threaded hold configured to mate with the threaded portion of the fastener.

A track chain member comprises a shoe member, and a first rail member extending from the shoe member, wherein the first rail member defines a track chain traveling direction and a lateral direction generally perpendicular to track chain traveling direction, a first support surface extending generally in both the track chain traveling direction and the lateral direction defining an outer lateral extremity, and a first crest shaped member disposed laterally adjacent the outer lateral extremity of the first support surface.

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 and a first rib defining a first concave radial portion.

A track link for a ground-engaging track system includes an elongate link body having an upper rail surface located in part upon each of a first link strap, a second link strap, and a middle section of the track link. The upper rail surface is formed by a wear band of sacrificial wear material having a hardness that is varied lengthwise along the upper rail surface to retard scalloping of the track link during service and forming relatively softer zones in the first and second link straps and a relatively harder zone within the middle section. Methodology for making such a track link is also disclosed.

A track chain member comprising a shoe member defining a track chain traveling direction and a lateral direction, the shoe member further defining a first lateral end, a second lateral end, and a ground engaging surface spanning from the one end to the other end; wherein the shoe member further defines a first side void proximate the first lateral end, a second side void proximate the second lateral end, and the first side void terminates a first predetermined distance from the first lateral end and the second side void terminates a second predetermined distance from the second lateral end.

A track system for traction of a vehicle (e.g., an all-terrain vehicle (ATV), an agricultural vehicle, etc.) may be designed (e.g., may comprise non-pneumatic tires) to enhance its use or performance and/or that of the vehicle such as, for example, by being lightweight and/or by better handling loads, including, for instance, those resulting from track tension within the track system and/or from unevenness or other aspects of the ground, including encounters (e.g., impacts) with obstacles on the ground (e.g., rocks, portions of trees, debris, bumps, abrupt changes in ground level, etc.). The track system may comprise tension-based non-pneumatic tires.

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.

A machine track includes a track shoe having a first outboard edge and a second outboard edge, and a first set of pin lugs and a second set of pin lugs. A roller pad is positioned between the sets of pin lugs and includes a roller contact surface extending between a first roller pad end and a second roller pad end. The first roller pad end includes a relatively softer material, and the second roller pad end includes a relatively harder material that forms a trimming edge for trimming off interfering material of an adjacent track shoe in a machine track that is plastically deformed by way of roller contact with the adjacent track shoe during service.

The present invention provides a tracked wall climbing robot including a rack, two sets of track mechanisms and power components operating respectively in cooperation with the two sets of track mechanisms. Each set of track mechanism includes a track, a driving wheel, a tensioning wheel and a plurality of load bearing wheels, wherein the driving wheel, the tensioning wheel and the load bearing wheels are sleeved with the track, the tensioning wheel is used for tensioning the track, the driving wheel, the tensioning wheel and the load bearing wheels are rotatably arranged on the rack respectively through a driving wheel axle, a tensioning wheel axle and load bearing wheel axles, the driving wheel drives the tensioning wheel and the load bearing wheels to rotate through the track, the track is composed of a plurality of convex platforms, and attractive components are arranged in gaps between the convex platforms.
