Abstract
A four pivot point track suspension apparatus for a vehicle. The track suspension apparatus includes a frame, a drive wheel, an undercarriage, and a continuous flexible track. The continuous flexible track is engaged by and driven by the drive wheel which is rotatably attached to the vehicle and operably attached to the frame. The undercarriage includes a leading equalizer pivotally mounted to the frame and having leading and trailing idler rollers rotatably attached thereto and a trailing equalizer pivotally mounted to the frame having an intermediate idler roller assembly and trailing idler rollers rotatably attached thereto. The leading equalizer is spring biased against the frame to maintain constant tension on the track and to ensure that all the idler rollers are in constant engagement with the track.
