Balancelike distribution links are pivotally mounted on a slewing frame as a truck at certain intervals, and another balancelike distribution links are pivotally mounted directly or indirectly on the axles of the wheels. The distribution links on the slewing frame and the distribution links on the axles are joined alternately with connecting bodies which are connecting links or connecting rollers.
