Abstract
A vehicle includes a plurality of track systems, a fluid pump, a plurality of fluid lines fluidly connecting the fluid pump to at least some of the tires of the wheels of each of the track systems, a plurality of pneumatic inflation actuators, a plurality of pneumatic deflation actuators, and a system controller. The system controller is in electronic communication with the fluid pump, the plurality of pneumatic inflation actuators, and the plurality of pneumatic deflation actuators. The system controller is operable to selectively adjust fluid pressure in select ones of the wheels of any one of the track systems of the vehicle by actuating corresponding ones of the plurality of pneumatic inflation actuators and the plurality of pneumatic deflation actuators. A track system has at least one of the leading idler wheels, trailing idler wheels, and mid-roller wheels including a tire containing a fluid.
