Abstract:
An electromotive linear drive with a drive unit having a drive motor and a spindle driven by the drive unit. The drive includes a spindle nut disposed on the spindle. The spindle nut is movable longitudinally on the spindle. A lifting tube is operatively connected to the spindle nut so that the spindle nut moves together with the lifting tube. A connecting part is disposed on a free end of the lifting tube. A braking assembly is disposed in the lifting tube and is operatively connected to the spindle nut via an adjustable, frictional connection. The braking assembly is manipulable. During operation of the drive motor, the spindle nut frictionally engages the braking assembly, preventing rotation of the spindle nut. The frictional connection may be adjusted to permit the spindle nut to rotate with respect to the spindle, thereby manipulating a linear speed component of the lifting tube.
