An endless vehicle track assembly with improved response to pitch, roll and yaw includes an adjustable main frame supported for tilting movement on an axis transverse to the main frame. The main frame first end is equipped with a tensioning bracket that includes a first axle tube to accommodate a first axle with end wheels in spaced apart relation to each other. The main frame second end is equipped with a pivotal alignment bracket having a second axle tube to accommodate a second axle with a second set of end wheels in spaced apart relation to each other. The main frame body is equipped with a reinforcing bracket pivotally attached to a main frame top side intermediate the first and second ends and equipped with an implement axle tube for pivotal movement relative to said mainframe. A plurality of bogie wheels are attached to the roller beams.

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.

The present technology generally relates to a vibration damping system for a track system of a vehicle. The vibration damping system comprises a leading frame member at least indirectly pivotally connectable to a chassis of the vehicle; a trailing frame member at least indirectly pivotally connectable to the chassis of the vehicle, the trailing frame member pivoting independently from the leading frame member; and a resilient member pivotally connected to the leading frame member and to the trailing frame member. The resilient member extends generally vertically between the leading frame member and the trailing frame member.

A compact work machine, such as a compact track loader and/or a compact utility loader, which can carry and operate a wide range of attachments while maintaining a reduced operating footprint.

A support structure, which is for a track system, includes a shaft, a wheel assembly and a deformable portion. The wheel assembly is connectable to the shaft, which has a shoulder at one end, such that a lateral side of the wheel assembly is engageable with the shoulder. The deformable portion is connected to one of the shaft and the wheel assembly, and is disposed, when the wheel assembly is connected to the shaft, between the lateral side of the wheel assembly and the shoulder. The deformable portion is configured to, when deformed, provide a seal between the shaft and the lateral side of the wheel assembly.
