SELF-PROPELLED SURFACE MILLING CUTTER
The present invention relates to a self-propelled surface milling cutter, for example in the form of an asphalt milling cutter, a snow blower or a surface miner, 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. In accordance with the invention, 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 rotato-rily entrains the drum body, in order to be able to transmit the rotary drive move- ments of the drive part to the drum body. However, the rotating drive part can be reciprocated relative to the drum body in direction of its longitudinal axis, in order to compensate an axial offset for example as a result of thermal expansions or dimen-sional tolerances or mounting inaccuracies.
