Abstract
An antiskid device for vehicle wheels, having a retaining device which is coaxially attached on one side of the wheel rim or the wheel disc and which via arms disposed transversely of the running direction and engaging over the wheel running surface retains an antiskid chain bearing against the wheel running surface, the arms being pivotably attached to the retaining device via joints whose pivots are at right angles to the wheel axle and to the wheel radius extending through the joint, while via the joint the arms can also be pivoted around an axis parallel to the wheel axle, the arm ends attached in the joint being located in a recess in the retaining device which opens in the direction of the wheel side and has inclined lateral surfaces which return the arm end from an inclined position to a radial position.
Claims7
An antiskid device for vehicle wheel having a running surface, the device comprising:
- a retaining disk having a central axis and mountable coaxially with the wheel from one side thereof;
- a plurality of projections formed at equal angular distances on and extending radially outwardly from the retaining device, each of the projections being provided with:
- a respective recess facing the wheel and being formed with a respective pair of lateral surfaces extending radially outwardly toward the running surface and converging axially outwardly, and
- a respective joint extending perpendicular to a radius of the respective projection transverse to the respective pair of lateral surfaces;
- a respective arm extending transversely to a running direction of the wheel and formed with a respective inner end mounted on each of the projections and with a respective outer end extending across the running surface of the wheel;
- and
- respective antiskid means for preventing a vehicle from skidding and formed on the respective outer end of the respective arm, each arm being pivotally mounted on the respective joint and also so as to pivot about a respective pivot axis parallel to the central axis, the lateral surfaces of the respective recess engaging the inner end for guiding same in an operative position of the respective arm upon engaging of the respective antiskid means with a ground.
