Travel drives 1 for the driving and steered wheel 2 of vehicles in the so-called driverless transport system (FTS) permit a height compensation, so that an adjustment occurs in the event of ground irregularities. In order to permit absolutely vertical and positionally neutral height compensation, four vertically arranged racks are provided on an outer ring 3 of a slewing rim bearing for the pivoting for steering of the driving and steered wheel 2, which racks are longitudinally guided in a connection housing 4 and likewise engage in two double pinion shafts engaging with one another. <IMAGE>
