Abstract: A traction device for a wheeled vehicle comprises a rotor mounted to a supported component of the vehicle and displaceable between a deployed position, in which the rotor is close to the ground and in contact with the tire of a driven wheel of the vehicle so that when the tire rotates, the rotor rotates through frictional engagement therewith, and a stowed position, in which the rotor is farther from the ground and is spaced from the wheel. At least one elongate traction element is attached to the rotor at a location spaced from the axis of rotation of the rotor, so that when the rotor rotates due to frictional engagement with the rotating tire, the traction element is subject to centrifugal force and is extended from the rotor and passes between the tire and the ground.

Abstract: An anti-skid device of the type including an arm, carrying in its outer end a chain-provided pulley that is brought in contact with a vehicle wheel so that the chains are thrown in under the vehicle wheel. The arm is, in its inner end, journaled in a U-shaped or fork-shaped bracket via a short axle that, in its ends, rests in bowl-shaped hemispherical bearings that are threaded into the legs of the bracket. The bearing bowls are pretensioned against the axle. At the apex of the shaft's spherical ends, recesses are made that take-up lubrication grease and, in this way, a point-like contact between the bearing shells and the axle is eliminated.

Abstract: A chain-carrying pulley (1) is journalled on a shaft (3) fastened to an arm (4) pivotally connected to another arm (5) which in turn is rigidly fastened to the rear axle casing (6) of a vehicle. An inflatable bellows (7) extends between the arms. When inflated, for instance by pressurized air, the bellows displaces the movable arm (4) from a folded position relative to arm (5) bringing the pulley (1) into contact with the wheel. The pulley is returned to a storage position by springs (10) joined to the arms when the bellows is deflated.

Abstract: A cable type tire chain has traction sleeves on the cross members located only adjacent to the shoulders of the tire. The center portion of the cross members adjacent to the middle of the tire tread is free of traction sleeves. The traction sleeves are spaced away from the middle of the tire tread by either a coil spring through which the cross member cable extends or by beads attached to the cable. The cross members are attached directly to the side members of the tire chain by flat profile hooks formed from rectangular strips of metal, so that the cross members lie close to the sidewalls of the tire. The invention provides improved traction and reduced wear of both the tire and the tire chain.
