Abstract

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.
