A pivot assembly for connecting a ground-contacting wheel assembly to a frame member of a track system assembly has a base defining a first interlocking member, a resilient body structured for being received at least partially within the base and having a second interlocking member connectable to the first interlocking member, and an axle assembly configured for rotatably connecting the ground-contacting wheel assembly to the frame member, the axle assembly including a third interlocking member connectable to the second interlocking member. The resilient body is at least partially wrappable around the peripheral surface of the axle assembly. Upon deformation of the resilient body, the axle assembly is pivotally movable relative to the frame member of the track system assembly about at least one of a longitudinal axis and a vertical axis.

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.

A wheel assembly, a track system and a vehicle are disclosed. The track system has a frame defining a longitudinal center plane, a wheel assembly rotationally and pivotably connected to the frame, and the endless track having the inner surface and surrounding the frame and the wheel assembly. The wheel assembly has a non-linear axle and a wheel. The non-linear axle has a first segment and a second segment. The wheel is rotationally connected to the first segment extending along a rotation axis of the wheel. The second segment being pivotably connected to the frame. The second segment is offset from the first segment so that the second segment is closer to an inner surface of an endless track than the first segment.

An idler adjustment assembly includes a support block; a first set of one or more adjustment components to move a first wear component between a first plurality of positions that are adjacent to an external surface of a first side of the support block; a second set of one or more adjustment components to move a second wear component between a second plurality of positions that are adjacent to an external surface of a second side of the support block; a first set of one or more alignment components to maintain a first alignment of the first wear component relative to the external surface of the first side of the support block; and a second set of one or more alignment components to maintain a second alignment of the second wear component relative to the external surface of the second side of the support block.

A track system for a vehicle on a ground, wherein the track system is reconfigurable, such as by rearranging or otherwise altering one or more components of the track system (e.g., wheels, pivots or other joints, frame members, etc., by changing their position, movability, etc.) and/or by repositioning the track system relative to a frame of the vehicle, which may be useful, for instance, to enhance performance of the vehicle (e.g., maximize or otherwise increase traction and/or pulling force (e.g., drawbar pull); improve steerability; etc.), ride quality (e.g., comfort), effects on the ground (e.g., minimize or otherwise reduce soil compaction and/or soil shear stress; provide headland protection; etc.), and/or other aspects of the track system and/or the vehicle, and/or for various other purposes.

A track assembly includes an elongated main frame supported for pivotal movement on a transverse axis and having opposite end portions supporting a set of end wheels. An endless flexible belt extends around the end wheels and has an upper run and a lower run for engaging the ground. A plurality of longitudinally spaced bogie wheels are positioned below the main frame and engage the lower run of the belt. The bogie wheels are carried by bogie frames supported for vertical movement and also for tilting movement relative to a plane defined by the axes of the end wheels. The bogie frames are urged or biased downwardly against the lower run of the belt by compression members extending from the main frame and preferably in the form of annular rubber spring members.
