Abstract: In a device with a centrifugal brake, in particular for the automatic winding up of an electrical cable for an electrically driven apparatus on a rotatable drum, that is journalled with its hub on a pivot spindle standing on a base plate and is braked on the base plate, the centrifugal brake is formed as a brake wheel (5) revolving inside a brake collar (6) and supported on a journal pin (4) on the base plate (1) laterally of the pivot spindle (2), the brake wheel being driven from the drum with a high gearing ratio. Preferably, the brake wheel (5) possesses two centrifugal weight segments (12) that are connected through resilient flexible arms (5.3) with its hub as a single piece. Advantageously, the pivot spindle (2) for the drum (3) as well as the journal pin (4) for the brake wheel (5) and the brake collar (6) form a unitary injection molded part (FIG. 1, 2) with the base plate (1).

Abstract: In a device for automatically winding up an electrical cable for an electrically operating apparatus on a drum, the drum is journalled with its hollow hub in two sleeve bearings of different diameter formed with a pivot spindle fixed on a base plate. Between the bearings two sliding contact elements comprised of contact rings and contact springs are arranged, of which the contact rings are arranged non-rotatably on the pivot spindle, and the contact springs are arranged in a contact carrier insertable in a recess in the hub. The opening of the hollow drum hub (3.1) facing the base plate (1) is provided with a collar (3.11) and locking pawls (1.2) are provided on the base plate (1) that engage behind the collar (3.11) of the hub (3.1) so that the drum (3) is secured against axial drawing off of the pivot spindle (2). The contact carrier (12) is insertable in a radial direction in the recess (3.12) of the hub (3.1) and is held therein through a locking connection.
