Abstract

A driving connection between spline shafts and spline bore hubs of safety steering columns, where the shaft and the hub, because of prestressing torque existing between the two, can be shifted with respect to one another axially but are free from torsional play. The prestressing torque is generated by a torsion spring element supported between the shaft and the hub. The required freedom from torsional play is achieved by arranging a main hub and an additional hub on the shaft with the torsion spring element connecting the main hub with the additional hub so that the main hub and the additional hub are spring loaded in opposite rotational directions.
