Abstract: A steering knuckle gearbox assembly comprises a body having a housing portion having a cavity defined in the housing portion; a mating portion connected to the housing portion and being pivotably mountable an axle frame of a vehicle; and a mounting portion for having a steering link of the vehicle pivotably mounted to the mounting portion. An input shaft is rotationally supported by the housing portion and extends into the cavity at its one end and is operatively connectable to a drive axle of the vehicle at its other end. An output shaft is rotationally supported by the housing portion and extends into the cavity at its one end and is operatively connected to the input shaft at its other end. The output shaft is offset in height from the input shaft. A steerable track system for a vehicle is also described.

Abstract: A steering knuckle gearbox assembly (138) comprises a body having a housing portion (140) having a cavity defined in the housing portion (140); a mating portion (142) connected to the housing portion (140) and being pivotably mountable an axle frame (106a) of a vehicle; and a mounting portion (144) for having a steering link (90) of the vehicle pivotably mounted to the mounting portion (144). An input shaft (176) is rotationally supported by the housing portion (140) and extends into the cavity at its one end and is operatively connectable to a drive axle (94) of the vehicle at its other end. An output shaft (187) is rotationally supported by the housing portion (140) and extends into the cavity at its one end and is operatively connected to the input shaft (176) at its other end. The output shaft (187) is offset in height from the input shaft (176). A steerable track system for a vehicle is also described.

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 leading pivot and a trailing pivot. A multi-member frame assembly including: a leading frame member pivotably connected to the attachment assembly via the leading pivot for pivoting about a leading pivot axis; a trailing frame member pivotably connected to the attachment assembly via the trailing pivot for pivoting about a trailing 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: A steerable track system usable with a vehicle that has a chassis, an axle frame extending laterally outwardly from the chassis and having an attachment portion at an end thereof to which the steerable track system is connectable, and a driven shaft extending laterally outwardly from the chassis suitable for driving the steerable track system. The steerable track system has a frame having a cavity defined therein and being operatively connectable to the axle frame so as to be pivotable about a steering axis for steering the track system, and a gear train with components disposed in the cavity. The gear train transmits driving forces from the driven shaft to a driven wheel assembly of a plurality of track-supporting wheel assemblies. An endless track extends around the track-supporting wheel assemblies and is drivable by the driven wheel assembly.

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.
