Support structure, track system having a support structure, guide rail and track system having a support structure and a guide rail

A support structure for connecting support wheel assemblies to a frame of a track system, the track system defining a longitudinal direction, the support structure comprising:

• an axle assembly pivotally connectable to the frame, the axle assembly including:
• an axle;
• and
• a longitudinal member connected to the axle, the longitudinal member having a first end portion and a second end portion, the longitudinal member defining a longitudinal pivot axis extending between the first and second end portions;
• and
• a biasing component in contact with the longitudinal member, the biasing component configured to connect the axle assembly to the frame, and the biasing component biasing the axle assembly toward a first configuration.

A track system defining a longitudinal direction, the track system comprising:

• a frame;
• a sprocket wheel assembly rotationally connected to the frame;
• at least one idler wheel assembly rotationally connected to the frame;
• a guide rail connected to the frame and extending in the longitudinal direction, the guide rail having a first portion having a first width and a second portion having a second width, wherein the second width is larger than the first width;
• at least one support structure pivotally connected to the frame, the at least one support structure comprising:
• an axle;
• at least two support wheels connected to the axle;
• and
• a longitudinal member connected to the axle, the longitudinal member having a guide rail contacting portion;
• an endless track surrounding the frame, the sprocket wheel assembly, the at least one idler wheel assembly, the guide rail and the at least one support structure.
