Adjustment drive for a steering column, drive unit for an adjustment drive, motor-adjustable steering column for a motor vehicle and method for producing an adjustment drive for a steering column

摘要

The invention relates to an adjustment drive (5, 6) for a motorized steering column (1) for a motor vehicle, comprising a transmission (8, 9) with a drive assembly (82, 92) in which a drive shaft (A) can be driven to rotate Drive wheel (922) is mounted, which is in operative engagement with a gear wheel (912), which is mounted rotatably about a gear axis (G) in a gear assembly (81, 91) and which is connected to a threaded spindle (52) or a spindle nut (61) a spindle drive, the drive assembly (82, 92) and the gear assembly (81, 91) being connected to one another by at least one joint (93). In order to be able to produce the joining connection (93) reproducibly with less processing and assembly effort, it is proposed according to the invention that the drive assembly (82, 92) and / or the gear assembly (81, 91) have at least one elastic tensioning element (94) for bracing of the drive assembly (82, 92) and gear assembly (81, 91) in the area of the joint connection (93).
