Abstract:
The invention relates to an electromotive linear drive (10) with a housing (11) that is equipped with a drive unit, the output member of which is designed as a linearly movable spindle nut that is operatively connected to a connecting part (14) for connecting to another component. According to the invention, the spindle nut is engaged with the connecting part (14) in the normal operating state by a first coupling part (17) and a second coupling part (18) that is engaged with said first coupling part, and the driving connection can be decoupled by a movement of at least one coupling part (18) in the longitudinal direction of the spindle. Said movable second coupling part (18) is preferably designed as a sliding sleeve which is provided with an internal profiled section that is engaged with the profiled section of the first coupling part (17) and with the profiled section of the connecting part (14) in the normal operating state.
