Abstract
The present invention generally relates to vehicle and machinery in agriculture, construction, forestry, mining and powersport. It further generally relates to track systems and traction assemblies used with such vehicles. The track system comprises a drive wheel and a plurality of idler wheels mounted on a support frame. At least one of the plurality of wheels is operatively mounted on the support frame via a damping system adapted to provide a damping value dynamically varying as a function of the load applied. Track systems do not benefit from the damping provided by the layer of air within the tires. The disclosed damping system has the objective to overcome one this drawback by providing a smooth ride for tracked vehicles. The damping system comprises a cylinder fluidly connected to a reservoir. Damping ratio is varied by varying a flow circulating area between the cylinder and the reservoir.
