The annular backing member is in press-fit engagement with the annular race member such that the radial outer face of the annular race member engages the radial inner surface of the annular backing member and the second axial end face of the annular race member engages the axially-facing base surface of the annular backing member such that the members are unitized.

Adjustment drive for a steering column, motor-adjustable steering column for a motor vehicle, and method for adjusting a bearing assembly of an adjustment drive

A motor adjustment drive for a vehicle steering column includes a threaded spindle with an axis. The threaded spindle engages a spindle nut. A drive unit and a gear wheel which is connected to the spindle nut or the threaded spindle for rotation therewith is driveable to rotate by the drive unit and is rotatably mounted in a bearing housing between two outer bearing rings that are axially supported at the bearing housing. The outer bearing rings each have, on their sides facing one another, a circumferential outer bearing face that is coaxial to the axis. Each outer bearing face lays opposite a bearing face embodied on the end side at the gear wheel. An outer bearing ring is axially resiliently supported at the bearing housing via an elastic element, which exerts an axial force that biases the two outer bearing rings toward each other.
