ABSTRACT:
An apparatus for providing additional traction to the wheels of a vehicle during inclement conditions utilizes an adapter to accommodate its use with a variety of sizes of vehicle wheels and has features to permit its convenient installation and removal from the wheels of the vehicle. A vertical disc has a plurality of traction elements mounted on its periphery to engage the terrain, with the disc being cooperatively connected to the wheel adapter by means of a large coil spring. The spring permits flexure of the disc and traction elements in four dimensions, i.e. rotatively about the wheel axis, horizontally about the longitudinal axis of the vehicle axle to permit the disc to cant inwardly into contact with the top of the wheel or tire of the vehicle, vertically with respect to the terrain, and along the horizontal axis of the wheel axle toward and away from the wheel. The use of the single spring to provide the various modes of flexure facilitates simplicity in the construction of the apparatus. Different traction elements are provided for snow, ice sand and mud, and are conveniently changeable for such conditions. A split disc mounting arrangement provides for convenient mounting and dismounting of a traction assembly to a mounting assembly without removing all the wheel lugs from the vehicle.
