ABSTRACT:
A track vehicle that uses a sliding rail type suspension, which is mounted on the outside of the vehicle frame. A supporting frame is used to support the outer edge of the track. The use of this type of suspension allows the vehicle to operate at speeds in excess of 50 miles per hour. A support shaft attaches to the track suspension arm. The support shaft is secured to the vehicle using a pair of spaced apart bearings. These bearings restrain the shaft, and thus the track from a deflectional force that causes the track to splay outwards. The shaft and bearings prevent this splaying action, thus permitting the vehicle to operate at high speeds.
