In some examples, a vehicle track includes a track body and a plurality of cores, where each core of the plurality of cores is at least partially embedded within the track body. Each core of the plurality of cores may include a body including a first end and a second end opposite the first end. The body may have a body width measured along a first axis extending between the first and second ends, and a body length measured along a second axis orthogonal to the first axis. Each core of the plurality of cores also may include a first edge portion extending from the first end of the body and a second edge portion extending from the second end of the body, where each of the first and second edge portions defines at least one protrusion that extends from a major surface of the respective body. The at least one protrusion may have a protrusion length that is less than the body length.

Embodiments of the present invention discloses a track mechanism, including a base; a driving wheel, disposed on the base rotatably; a guide wheel, configured to support the base together with the driving wheel and disposed movably relative to the base; a track, wound around the driving wheel and the guide wheel for a circle, to perform rotary motion around the driving wheel and the guide wheel; and a tensioning mechanism, including an adjusting member connected to the guide wheel to change a position of the guide wheel and an elastic member located between the adjusting member and the base, the elastic member provides a driving force that enables the adjusting member to move, and the adjusting member drives the guide wheel to move and tension the track.

The elastic crawler according to this disclosure is an elastic crawler comprising on an inner circumferential side a plurality of engaging portions (14) respectively engageable with a plurality of pin members (22) arranged at a spacing in a circumferential direction of a sprocket, wherein: the engaging portions (14) have a pressure receiving surface (14a) which receives the pin members (22), an outline shape in side view of the pressure receiving surface (14a) being formed by an envelope L.sub.1 drawn by an outer end of the pin members (22) when the sprocket rolls coaxially with a central axis of a virtual rotor with a rolling diameter D.sub.1 as defined in D.sub.1=(pitch of the engaging portions)(number of pin members)/()a, and 0.9a<1, together with the virtual rotor on a plane.

A track system for traction of an off-road vehicle such as a snowmobile or an all-terrain vehicle (ATV). The track system comprises a track-engaging assembly and a track disposed around the track-engaging assembly. The track system may be configured to have a reduced noise profile so as to generate less noise, enhanced track rigidity characteristics to improve its traction and floatation, and/or other features improving use and performance of the off-road vehicle.
