ABSTRACT:
A suspension system for tracked vehicles has a plurality of interconnected air bags that is used to more evenly distribute the weight of the vehicle superstructure over the belt track. The more even weight distribution improves floatation of the vehicle over the ground, and reduces instability and wear of the superstructure. A tensioner with a pressurized air bag can be used to increase the tension on the belt track during vehicle operation. The pressure in the tensioner air bag can be reduced to ease the tension on the belt track for efficient servicing.
