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.
