Abstract: A suspended undercarriage assembly connectable to a multi-member frame assembly of a track system includes a beam having a leading portion and a trailing portion, at least one support wheel assembly connectable to the beam, at least one of a leading resilient bushing assembly and a trailing resilient bushing assembly including a bushing having an opening defined therein and being shaped and dimensioned for promoting deformation of the bushing in at least one of a vertical direction and a lateral direction. The bushing is resiliently deformable to permit movement of the beam relative to the multi-member frame assembly in the vertical direction and in the lateral direction, and to resiliently bias the beam towards a rest position with respect to the multi-member frame assembly. A track system having the suspended undercarriage assembly is also provided.

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: 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: A track system includes a primary wheel structured to be rotationally attachable to a vehicle, a frame rotationally supporting a plurality of secondary wheels; a sub-frame supported by the frame. The sub-frame rotationally supports the primary wheel. The primary wheel and the plurality of secondary wheels support an endless track thereabout. A fastener secures the frame to the sub-frame and prevents pivoting of the frame relative to the sub-frame about the pivot axis. The fastener is disengageable. The frame is pivotable relative to the sub-frame about the pivot axis when the fastener is disengaged. The fastener is re-engageable to secure the frame to the sub-frame in any one of a plurality of different adjustment positions. In some implementations, a pivot member extends in a vertical direction between the sub-frame and the frame and defines a pivot axis of the frame.

Abstract: A grouser assembly is selectively attachable to an endless track having a carcass, side edges and traction lugs. The grouser assembly includes a body having top and bottom faces. The body includes a recess defined in the bottom face that is shaped to receive a traction lug of the endless track. The grouser assembly further includes ground-contacting projections connected to the body and extending away from the top face, and first and second attachment assemblies connected to the body. The second attachment assembly has an attached configuration and a released configuration, and is positioned relative to the first attachment assembly such that when (i) the traction lug is received in the recess, (ii) the first attachment assembly attaches the grouser assembly to the carcass, and (iii) the second attachment assembly is in the attached configuration, the second attachment assembly attaches the grouser assembly to the endless track.
