A triangular track suspension system includes a drive sprocket, a track frame having idler wheels mounted on its ends, and a track draped about the drive sprocket and idler wheels. One of the idler wheels is mounted for fore and aft movement relative to the track frame. A take up mechanism is provided that moves the idler wheel in a forward direction as the track frame rocks to maintain a substantially constant circumference around the idler wheels and drive sprocket.

A triangular track suspension system for a vehicle comprising: a pivot shaft affixed to said vehicle, a drive sprocket mounted on said vehicle and positioned adjacent and above said pivot shaft; a track frame having first and second ends, said track frame being mounted for rocking movement on said pivot at a location between said first and second ends, an idler wheel link pivotally attached to the first end of the track frame and extending upwardly therefrom and terminating in an upward end, a first idler wheel mounted for rotation on the upper end of said idler wheel link, a second idler wheel and means mounting said second idler wheel for rotation on the second end of said track frame, a continuous track engaging said drive sprocket, said first idler wheel, and said second idler wheel, and take-up means mechanically linking said idler wheel and link and said vehicle for moving the upper end of said idler wheel link away from said pivot shaft in direct reaction to the rocking motion of said track frame away from the horizontal so as to move said first idler wheel away from said pivot shaft and thereby maintain substantially constant circumference around the idler wheels and drive sprocket.
