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).
An adjustment drive for a motor vehicle, the adjustment drive comprising:
A drive unit for an adjustment drive comprising a gearbox with a drive wheel that is drivable in a rotating manner about a drive axis and operatively engages with a gearbox wheel that is mounted in the gearbox so as to be rotatable about a gearbox axis, wherein the gearbox is assembled from a drive module that has the drive wheel and a gearbox module that has the gearbox wheel, wherein the drive module and the gearbox module include respective joining sections that are directed towards one another and are connected via a joining connection, wherein for bracing the drive module and the gearbox module in a region of the joining connection at least one of the drive module or the gearbox module has an elastic tensioning element that tensions the joining sections against one another and the other of the drive module and the gearbox module has a form-fit element with an undercut, wherein the elastic tensioning element is engaged with the undercut of the form-fitting element to form the joining connection.
A method for producing an adjustment drive for a motor- adjustable steering column for a motor vehicle, the method comprising:
