Abstract: Damping system for an endless track system, comprising: Damper operatively connectable between frame members for damping relative movement therebetween, including: cylinder and piston movable therewithin forming variable volume chamber containing liquid. Reservoir containing liquid and gas connected to chamber. Conduits connecting chamber to reservoir for allowing liquid to flow therebetween to move the piston. Gas in reservoir applying hydrostatic pressure to liquid, biasing piston toward an extended position and causing piston to move theretowards when load on endless track system is decreased, and causing piston to move toward a retracted position when load on endless track system is increased.

Abstract: Track system for a vehicle having a chassis and a drive shaft extending laterally outwardly from the chassis includes: An attachment assembly having a pivot. A multi-member frame assembly including: a leading frame member pivotably connected to the attachment assembly via the pivot for pivoting about a pivot axis; a trailing frame member pivotably connected to the attachment assembly via the pivot for pivoting about the 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.

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 assembly includes components having particular features that, alone or in combination, participate in decreasing the vibrations 5 undergone by the vehicle. According to embodiments, split frames are used with suspension, tandem subassemblies, “tridem subassemblies”, adjustable damping components, drive shaft openings, lowering of resulting the track band tension and rosta assemblies.
