Abstract
A spindle drive (10), in particular for adjusting a movable part (58) in a motor vehicle, includes a drive assembly (42), which drives a drive wheel (18) supported on a spindle (16). The drive wheel (18) is rotatably supported in a support tube (14) that includes a receptacle (52) for a fastening device (54) for diverting crash forces. A guide tube (64) that accommodates the spindle (16) and overlaps axially with the support tube (14) is located coaxially with spindle (16).
Claims16
A spindle drive (10) for adjusting a movable part (58) in a motor vehicle, comprising:
- a drive assembly (42) for driving a drive wheel (18) supported on a spindle (16), the drive wheel (18) being rotatably supported in a support tube (14), wherein said support tube (14) includes a receptacle (52) for a fastening device (54) for diverting crash forces;
- a guide tube (64) that accommodates the spindle (16) and overlaps axially with the support tube (14), wherein said guide tube (64) is disposed coaxially with the spindle (16);
- and
- an adapter ring (88);
- wherein an end (20) of the support tube (14) or the adapter ring (88) includes an axial stop (75) for the spindle nut (76).

2 more elements
A method for manufacturing a spindle drive (10), comprising the following steps:
- providing a spindle (16);
- providing a drive wheel (18) supported on a spindle (16), the drive wheel (18) being rotatably supported in a support tube (14);
- providing a guide tube (64) that accommodates the spindle (16) and overlaps axially with the support tube (14);
