An endless track for traction of a vehicle, such as a construction vehicle, an agricultural vehicle, a forestry vehicle or a military vehicle. The endless track has an enhanced elastomeric material curing capability. In one embodiment, each of a plurality of elastomeric projections of the endless track, such as guide/drive projections or traction projections, comprises elastomeric material defining a cavity to enhance a curing process during manufacturing of the endless track. The cavity may be shaped such that, during the curing process, a heat conductor positioned in the cavity conducts heat from the heat conductor to the elastomeric material of the projection.

A crawler with a wear limit indicator comprises a crawler main body, sprocket holes formed to pass through a central portion of the crawler main body at equal intervals, core metals configured to be inserted and installed in-between the sprocket holes, left lugs configured to protrude from one surface of the crawler main body and simultaneously overlap with the sprocket holes and one of the core metals, right lugs configured to protrude from the other surface of the crawler main body and simultaneously overlap a pair of adjacent core metals, and a wear limit indicator configured to protrude from front and rear surfaces of the left lugs and the right lugs and inform that a replacement time for a crawler has come when worn-out surfaces of the left lugs and the right lugs are placed on the same horizontal plane as the wear limit indicator.

A rubber crawler includes: a crawler main body; a main cord layer overlaid on a crawler outer circumferential side of a main body inner circumferential portion, and including a main cord extending in a crawler circumferential direction; a first bias cord layer overlaid on a crawler outer circumferential side of the main cord layer, and including a bias ply configured with a bias cord, which extends obliquely with respect to the crawler circumferential direction; a second bias cord layer overlaid on a crawler outer circumferential side of the first bias cord layer, and including a bias ply configured with a bias cord, which intersects with the bias cord; and a protective cord layer overlaid on a crawler outer circumferential side of the second bias cord layer and overlaid on a crawler inner circumferential side of a main body outer circumferential portion, and is formed by one sheet of protective ply configured with a protective cord, which extends along a crawler width direction.

Provided is a novel elastic crawler with improved durability. An elastic crawler (1A) includes: a crawler body (2) made of an elastic material; a projection (3) arranged on an inner circumferential surface (21) of the crawler body (2) and made of an elastic material; and a resin member (31) forming a part of the projection (3). The resin member (31) is embedded in the projection (3) such that a lowermost end (31e) of the resin member (31) is arranged at a position higher than a lowermost end (3e) of the projection (3), and a part of the resin member (31) is exposed on a crawler-width-direction side surface (3b1) of the projection (3) and forms a crawler-width-direction side surface (2b1) of the projection (3).

Track system for a vehicle having a chassis and a drive shaft extending laterally outwardly from the chassis includes: An attachment assembly having a leading pivot and a trailing pivot. A multi-member frame assembly including: a leading frame member pivotably connected to the attachment assembly via the leading pivot for pivoting about a leading pivot axis; a trailing frame member pivotably connected to the attachment assembly via the trailing pivot for pivoting about a trailing pivot axis; a leading wheel-bearing frame member at least indirectly pivotably connected to the leading frame member; a trailing wheel-bearing frame member at least indirectly pivotably connected to the trailing frame member. A damper interconnecting the leading frame member and the trailing frame member. A leading idler wheel assembly; a trailing idler wheel assembly; support wheel assemblies; a gearbox; a sprocket wheel; and an endless track.

The present invention relate to a caterpillar track, in particular a rubber caterpillar track, with a track body ad with at least one outer profiling element, preferable with a plurality of outer profiling elements, which are directed outwardly away from the track body. The caterpillar track is characterized in that the outer profiling element has an outwardly directed grouser body and a grouser root, which connects the grouser body to the track body, wherein the outer profiling element has, at least in some sections, a marking which can make the boundary between the grouser body and the grouser root visually and haptically identifiable.

A band track including a band having an inner surface, an outer surface, a first side face, and a second side face; a plurality of teeth extending from the inner surface and spaced apart circumferentially around the inner surface; a plurality of lugs extending from the outer surface and each spaced a distance apart circumferentially around the outer surface; a plurality of living hinges defined within the band circumferentially between each of the plurality of teeth; and at least one fiber-reinforcement disposed circumferentially within a neutral plane of the plurality of living hinges and a method of making the same.

A track system for a vehicle (e.g., an all-terrain vehicle (ATV)) in which the track system is configured to enhance traction, floatation, and/or other aspects of its performance, such as, for example, to maintain proper contact with the ground (e.g., even if it is cambered) and/or to better absorb shocks when it encounters obstacles on the ground.

One general aspect includes a tethered temperature sensor (300) for use within a vehicle track (100). The tethered temperature sensor (300) includes one or more sensors (308) for measuring temperature located in a high strain and high temperature region (104) of the vehicle track (100).
