Track apparatus incorporating cantilever mounted wheels

A track apparatus having a frame, the track apparatus mountable on a rotatable axle of a vehicle, comprising:

• a continuous flexible track having an upper length and a ground-engaging lower length and including an inner surface;
• a drive wheel mountable to the rotatable axle of the vehicle for rotational movement therewith, the drive wheel engaging the inner surface of the flexible track along the upper length to drive the flexible track in response to rotation of the axle of the vehicle;
• first and second leading idler arms, each leading idler arm having a proximal end mounted to the frame and a distal end wherein the distal ends of the leading idler arms define a first gap therebetween;
• and
• first and second leading idler wheels, each leading idler wheel engaging the flexible track and rotatably mounted on the distal end of a corresponding leading idler arm along a common leading idler axis, the first and second leading idler wheels defining a leading idler void therebetween.

• first and second bogie arms, each bogie arm having a first end supported by the frame and a second end;
• first and second leading bogie wheels engaging the inner surface of the flexible track along the lower length, each leading bogie wheel rotatably mounted adjacent the second end of a corresponding bogie arm along a common leading bogie axis, the first and second leading bogie wheels defining a leading bogie void therebetween;
• first and second trailing bogie wheels engaging the inner surface of the flexible track along the lower length, each trailing bogie wheel rotatably mounted adjacent the first end of a corresponding bogie arm along a common trailing bogie axis, the first and second trailing bogie wheels defining a trailing bogie void therebetween;
• and
• a drive wheel mountable to the rotatable axle of the vehicle for rotational movement therewith, the drive wheel extending into the leading bogie void and into the trailing bogie void and engaging the inner surface of the flexible track along the upper length to drive the flexible track in response to rotation of the axle of the vehicle, wherein the drive wheel engages the flexible track along the upper length, extends into the leading idler void, and extends into the leading bogie void and at least partially intersects the leading bogie axis.
