Abstract
Official abstract text for this publication.
A cable drum for supplying power to an electrically powered utility vehicle, with an axially running winding body which can be set in rotation about a rotational axis in order to wind up and unwind an electrical cable, wherein on an inside, the winding body carries a plurality of fans which are configured to generate a cooling air stream directed radially outward with respect to a cylindrical drum wall.
First claim
Opening claim text (preview).
What is claimed is: 1. A cable drum for supplying power to an electrically powered utility vehicle, with an axially running winding body which can be set in rotation about a rotational axis in order to wind up and unwind an electrical cable, wherein on an inside, the winding body carries a plurality of fans which are configured to generate a cooling air stream directed radially outward with respect to a cylindrical drum wall, wherein the fans are attached to the inside of the winding body by means of a carrier plate, wherein the cooling air stream is conducted to a respective air outlet opening in the cylindrical drum wall via an air guide running between the carrier plate and the inside. 2. The cable drum as claimed in claim 1 , wherein in the region of the outlet opening, a separating means is provided, by means of which adjacent windings of a cable wound onto the winding body are held spaced apart in layers in order to form an air passage region. 3. The cable drum as claimed in claim 2 , wherein the separating means comprises rods arranged along an outer circumference of the winding body and/or a protrusion running along an outer circumference of the winding body.
