ABSTRACT:
A track device for mounting on a pneumatic tire fitted to the wheel of a vehicle to improve the buoyancy and traction of the vehicle over very soft terrain, the pneumatic tire including a tread surface across the width of the tire, a pair of side walls and an axis of rotation. The track device includes a plurality of bridge-like longitudinal and rigid traction blades having an inside surface made to rest on the tire across the width of the tread surface and a ground engaging outside surface, the traction blades being disposed on the tire in generally closely spaced-apart and parallel relationship to form an endless track. Each traction blade includes an intermediate bridge-like portion made to conform to the general cross-sectional shape of the tire, essentially flat side portions outwardly projecting from either side of the intermediate portion and generally parallel to the axis of rotation of the tire. The side portions sufficiently project beyond the width of the tire so as to provide a widening of the wheel of at least twenty percent of the width of the tire, thereby increasing the buoyancy and traction of the vehicle over very soft and muddy. Additional side members, integral with the traction blade are adapted to rest against the side walls of the tire so as to maintain the traction blade positioned over the tire. U-shaped linking members are provided for interconnecting the traction blades so that the traction blades form a tight track around the tire.
