Abstract

A known vehicle normally operating on independently suspended trailing arms nd pneumatic tires can be converted to a tracked vehicle by wrapping endless tracks around the tire tread areas in multiples of two. An expansible wheel-connector device is provided for causing the trailing arms and wheels to deflect in unison, thereby maintaining track tension and tire-track interengagement, minimizing uneven final drive torque loadings, and relieving the wheel bearing loads brought on by the addition of the track.
