Abstract
The invention relates to an adjustment drive (5, 6) for a motor-adjustable steering column (1) for a motor vehicle, comprising a gearbox (8, 9) having a drive module (82, 92) in which a drive wheel (922) which is able to be driven in a rotating manner about a drive axis (A) and which operatively engages with a gearbox wheel (912) that is mounted in a gearbox module (81, 91) so as to be rotatable about a gearbox axis (G) and is connected to a threaded spindle (52) or a spindle nut (61) of a spindle drive is mounted, wherein the drive module (82, 92) and the gearbox module (81, 91) are connected to one another by way of at least one joining connection (93). In order for the joining connection (93) to be able to be generated with less complexity in terms of machining and assembling in a reproducible manner, it is proposed according to the invention that the drive module (82, 92) and/or the gearbox module (81, 91) for bracing the drive module (82, 92) and the gearbox module (81, 91) in the region of the joining connection (93) have/has at least one elastic tensioning element (94).
