Abstract
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.
Claims38
A track for traction of a vehicle on a ground, the track being mountable around a plurality of wheels, the track being elastomeric to flex around the wheels, the track comprising:
- a carcass comprising a ground-engaging outer surface for engaging the ground and an inner surface opposite to the ground-engaging outer surface;
- and
- a plurality of traction projections projecting from the ground-engaging outer surface of the carcass;
- a plurality of guide lugs projecting from the inner surface of the carcass;
- and
- a plurality of transversal stiffening rods embedded in the track extending transversally to a longitudinal direction of the track;
- wherein at least a part of the carcass, the plurality of traction projections, and the plurality of guide lugs comprises fiber-reinforced elastomeric material including an elastomeric matrix and reinforcing fibers embedded in the elastomeric matrix;
- wherein the plurality of transversal stiffening rods are entirely embedded in the fiber-reinforced elastomeric material;
- and
- wherein longitudinally-adjacent ones of the transversal stiffening rods have at least one characteristic that is different from each other.
