Abrégé

The invention relates to a bearing arrangement for a rotatable holding element (2) on a pivot arm (3) which is pivotable between a rest position and a working position (4), wherein in the working position, the retaining element rotates in a plane of rotation with an adjustable angle of incidence (α) with respect to a tyre of a vehicle and continuously positions anti-skid elements (5) below the vehicle tyre. The bearing arrangement has a rotary bearing arrangement for the holding element and a ball joint (6) which can be locked after the adjustment of the angle of incidence (α). The ball joint is supported on the pivot arm by means of a part (7) which has a spherical bearing surface (8). The invention is characterized in that a spherical head shell (10) is arranged on the bearing surface, which spherical head shell has a central conical passage opening (11) in which an axle pin (9) with a first axle pin end (12), which is matched to the conical passage opening, can be braced so as to spread the spherical head shell.

Abrégé

The invention relates to a centrifugal chain system with a swivel arm (2) and a centrifugal chain mechanism at the end area of the swivel arm (2). There is also an actuation mechanism (10) to move the swivel arm (2) into position for use. Centrifugal chain systems of the prior art are relatively complicated and inflexible in installation. The invention utilizes a rotary drive (12) to transmit force to the swivel arm (2) by means of a traction drive mechanism (11).
