The work vehicle may further include a temperature sensor configured to sense a track temperature of the at least one track and a vehicle control system configured to receive the track temperature and to determine misalignment of the at least one track based at least in part upon the sensed track temperature.

An elastic crawler includes a plurality of elastic protrusion portions formed in a manner protruding on an inner circumferential face of a crawler main body, which is made of an elastic material and formed in an endless belt shape, at regular intervals in a crawler circumferential direction, and a resin cover member made of a resin material and covering a surface of each elastic protrusion portion, and the resin cover member covers the elastic protrusion portion to form a guide protrusion. In the elastic crawler, the resin cover member of the guide protrusion is put on the elastic protrusion portion to cover the surface of the elastic protrusion portion except a root portion 13r, and a reinforcing fiber part is embedded at least in the root portion of the elastic protrusion portion along a side face of the elastic protrusion portion.

The present invention relates to a running gear chain (2), in particular a bogie chain (2), having a flexible body (20), preferably an elastomer body (20), which is closed in endless fashion, or closable in endless fashion, in a running direction (A). The running gear chain (2) according to the invention is characterized by a multiplicity of rigid transverse elements (24) which are connected to the outer side of the flexible body (20) and extend substantially transversely with respect to the running direction (A), wherein at least some of the rigid transverse elements (24), preferably all of the rigid transverse elements (24), are arranged so close together in the running direction (A) that, with a planar extent of the flexible body (20), two immediately adjacent rigid transverse elements (24) make contact in the running direction (A).

A track assembly (15) for a track-driven vehicle, whereby the track-carrying beam (15) is arranged to hold a front and a rear wheel (16), one of which is driving, a plurality of carrying wheels about which wheels a continuous track travels, the track-carrying beam (15) is elongated and terminated by a first and a second gable end. The track-carrying beam (15) comprises an integrated compartment (37) and an opening (36) in one (35) of said gables, whereby the compartment (37) communicates with the surroundings via said opening (36), and whereby the opening (36) is arranged to allow for insertion of a transmission device for driving of said driving wheel (16) via the opening (36) in the compartment (37).

A track for traction of an off-road vehicle such as an agricultural vehicle, a construction vehicle, a snowmobile, or another vehicle operable off-road. The track is mountable around a track-engaging assembly including a drive wheel for driving the track. The track is elastomeric to be flexible around the track-engaging assembly. The track includes an inner surface for facing the track-engaging assembly, a ground-engaging outer surface for engaging the ground, and a plurality of traction projections projecting from the ground-engaging outer surface. The track may have various features to enhance its traction, its floatation, and/or other aspects relating to use and performance of a track system of the vehicle.

A track system for traction of a vehicle (e.g., a snowmobile, an all-terrain vehicle (ATV) etc.). The track system comprises a track and a track-engaging assembly for driving and guiding the track around the track-engaging assembly. The track system may have features to enhance its traction, floatation, and/or other aspects of its performance, including the track that may comprise reinforcing material (e.g., reinforcing polymeric material) that is stronger (e.g., stiffer, harder, and/or more resistant to wear) than elastomeric material of the track, such as to improve rigidity characteristics of the track, reduce noise generated by the track system, improve a resistance to wear of the track, and/or reduce a weight of the track. The reinforcing material may be provided as one or more thin layers constituting at least part (e.g., of a periphery) of one or more components of the track (e.g., a carcass, traction projections, and/or drive/guide lugs).

A traction improvement device provides increased traction to a tracked vehicle. The traction improvement device has two opposing brackets that are connected to opposite edges or flanges of a track of a tracked vehicle. A chain extends between the brackets. At least one of the brackets is a tensioner bracket that is configured to adjust the tension of the chain. The tension adjustment provides tension to the chain extending between the brackets, securing the traction improvement device on the outer surface (or gripping surface) of the track.

A track system includes an attachment assembly including at least one of a first pivot defining a roll pivot axis, a second pivot defining a pitch pivot axis, and a third pivot defining a yaw pivot axis of the track system. A frame assembly is disposed laterally outwardly from the attachment assembly and connected to the attachment assembly. The track system further includes at least one actuator for pivoting the frame assembly about at least one of the roll and yaw pivot axes, and at least one monitoring for determining, at least indirectly, at least one of a state of the track system and a ground surface condition. The at least one monitoring sensor is communicating with a track system controller to control the operation of the at least one actuator based on the at least one of the state of the track system and the ground surface condition.

Provided is a desulfurized rubber capable of producing a crosslinked rubber having an excellent mechanical strength. The desulfurized rubber contains a solvent-soluble rubber component A having a weight-average molecular weight of more than 260,000 and less than 600,000, and a solvent-insoluble rubber component B, wherein the content ratio of the rubber component B is less than 45% by mass of the total mass of the content a of the rubber component A and the content b of the rubber component B.

A rubber crawler 1 includes an endless crawler body 12 made of rubber, and a plurality of cores 13 embedded in the crawler body and arranged along the crawler circumferential direction, where at least a first projection on the crawler width direction first side in a pair of first projections of each core has a first recess R1 on a surface facing a second projection of another core of the surfaces on the two sides in the crawler width direction.
