Claims (6)

1. Elektromotorischer Linearantrieb mit wenigstens einer rotierend antreibbaren Gewindespindel, deren Steigungen der Gewindegänge außerhalb des Bereiches der Selbsthemmung liegen und auf die eine ausschließlich linear verfahrbare Spindelmutter aufgesetzt ist, dadurch gekennzeichnet, dass die Querschnitte der Gewindegänge der Spindel (9) und/oder die Oberflächen der Flanken der Gewindegänge einer Seite derart ausgebildet sind, dass ausschließlich in einer bestimmten Bewegungsrichtung der Spindelmutter (12) die Spindel (9) selbsthemmend wirkt.1. Electromotive linear drive with at least one rotationally drivable threaded spindle, the pitches of the threads of which lie outside the range of the self-locking and on which an exclusively linearly movable spindle nut is placed, characterized in that the cross sections of the threads of the spindle ( 9 ) and / or the surfaces the flanks of the threads on one side are designed such that the spindle ( 9 ) acts in a self-locking manner only in a specific direction of movement of the spindle nut ( 12 ). 2. Elektromotorischer Linearantrieb nach Anspruch 1, dadurch gekennzeichnet, dass die Querschnitte der Gewindegänge asymmetrisch sind.2. Electromotive linear drive according to claim 1, characterized in that the cross-sections of the threads are asymmetrical. 3. Elektromotorischer Linearantrieb nach Anspruch 1 oder 2, dadurch gekenn­ zeichnet, dass die Flanken jedes einzelnen Gewindeganges eine unterschiedli­ che Rauigkeit derart aufweisen, und/oder dass die Reibung so groß ist, dass in einer bestimmten Bewegungsrichtung der Spindelmutter (12) die Spindel (9) selbsthemmend wirkt.3. Electromotive linear drive according to claim 1 or 2, characterized in that the flanks of each individual thread have a differing surface roughness and / or that the friction is so great that in a certain direction of movement of the spindle nut ( 12 ) the spindle ( 9 ) has a self-locking effect. 4. Elektromotorischer Linearantrieb nach einem oder mehreren der vorhergehen­ den Ansprüche 1 bis 3, dadurch gekennzeichnet, dass die Spindel (9) des elektromotorischen Linearantriebes (1) bei der Bewegung der Spindelmutter in Richtung zum Antriebsmotor selbsthemmend und in der entgegengesetzten Richtung nicht selbsthemmend wirkt.4. Electromotive linear drive according to one or more of the preceding claims 1 to 3, characterized in that the spindle ( 9 ) of the electromotive linear drive ( 1 ) acts in the movement of the spindle nut in the direction of the drive motor self-locking and not self-locking in the opposite direction. 5. Elektromotorischer Linearantrieb nach einem oder mehreren der vorhergehen­ den Ansprüche 1 bis 4, dadurch gekennzeichnet, dass die Spindel (9) des elektromotorischen Linearantriebes (1) bei der Bewegung der Spindelmutter (12) in Richtung zum Antriebsmotor nicht selbsthemmend und in der entgegen­ gesetzten Richtung selbsthemmend wirkt. 5. Electromotive linear drive according to one or more of the preceding claims 1 to 4, characterized in that the spindle ( 9 ) of the electromotive linear drive ( 1 ) during the movement of the spindle nut ( 12 ) in the direction of the drive motor is not self-locking and in the opposite Direction is self-locking. 6. Elektromotorischer Linearantrieb nach Anspruch 4 oder S. dadurch gekenn­ zeichnet, dass die belasteten Flanken der Gewindegänge derart gestaltet oder eine solche Rauigkeit aufweisen, bzw. die Reibung so groß ist, dass beim Ver­ fahren der Spindelmutter (12) in Richtung zum Elektromotor die Selbsthem­ mung erzeugt wird.6. Electromotive linear drive according to claim 4 or S. characterized in that the loaded flanks of the threads are designed in such a way or have such roughness, or the friction is so great that when driving the spindle nut ( 12 ) in the direction of the electric motor Self-locking is generated.
