Abstract
A backlash-free spindle nut is disclosed with a thread that can be meshed with a spindle. The spindle nut has a first nut part with a first internal thread and a second nut part with a second internal thread that can be twisted in relation to the first nut part. To generate a preload between the first nut part and the second nut part, the spindle nut has an elastic element. The preload can be adjusted through relative twisting between the first nut part and the second nut part. The elastic element can work between the first nut part and a secure intermediate part, whereby relative twisting between the first nut part and the second nut part can be locked by locking a relative twisting position between the second nut part and the intermediate part.
