WIPO Patent Application WO/2016/176631

A3

Disclosed embodiments include power machines (100; 200; 302), track frame assemblies (305), and apparatus for mounting a track frame assembly to a frame of a power machine. In various disclosed embodiments, mounting structures (310; 340; 350) mount a track frame to the machine frame (335). In some exemplary embodiments, each mounting structure includes two torsional joints and at least three non-torsional joints between the machine frame and the corresponding track frame. The two torsional joints can be provided by torsion shafts (405) and the corresponding attachments to front and rear arms (420). In exemplary embodiments, the at least three non-torsional joints are substantially free to rotate and can include a joint between a front axle (435) and the track frame, a joint between a rear axle (435) and a link (500), and a joint between a link pin (520) and the track frame. In some exemplary embodiments, the front or rear arms are oriented relative to corresponding torsion shafts to improve performance.
