Abstract

The present disclosure relates to a self-propelled surface milling cutter, with a working assembly comprising a rotatingly drivable drum body, and at least one drum drive unit which is accommodated in the interior of the drum body and forms at least part of a rotatable bearing of the drum body on a drum supporting frame, wherein the at least one drum drive unit includes a stationary drive part attached to the drum supporting frame and a rotatable drive part connected with the drum body. The rotatable drive part of the drum drive unit is mounted on the drum body by a positive entrainment connection in a torque-transmitting, but longitudinally movable manner. The entrainment connection rotatorily entrains the drum body, in order to be able to transmit the rotary drive movements of the drive part to the drum body.
