Purpose of the invention

The aim of the invention is to provide a fully automatic tensioning drive which, in the case of local separation of the spinner handle and spindle element, connects the spanner handle and the tensioning element by means of an external coupling, performs the rotating tensioning motion by a torque, and disengages the clutch by a final displacement and local · separation of Spsnnantrleb and 8pennelement realest and the lat easily produced, at high transmittable torque extreme Achaabwelchungen between clamping drive and 8pannelement and the above known technical solutions a much lower maintenance and care when Einaau In vollutometlslerten Fertlgungsllnlen with much higher reliability.

The essence of the invention consists in the fact that the exclusive feed motion and the smooth rotation deaerate

Kb.oplungaeggregetea mediated by a combination of special in-line echsymetrlschor elektromegnetlscher Couplings with different rotetlonssymetrischen movement elements exclusively by daa alternating Zuschslten the electromegnetlschen couplings can be realized without the use of mechanical Steuermechenlsmen. According to the invention, the electromagnetic telescopic coupling consists of the Qehluse, the drive shaft located in the Qehluse

with the threaded stub, the Adepterring in the Qehluse, located at the Adepti ring and in the drive shaft

Drive shaft with the feed screw, the clutch unit and the two three-part controlling the functions Connecting couplings. Dsbei Is the drive shaft, ice hollow body executed utid in a nutstick ending, Im Gehluse eusschlleßllch drehbsr. The adapter piece is located externally on the main body and can be turned on by means of the first connection coupling

be rigidly coupled to the Gehluse and by means of the second connection coupling with the drive shaft.

The drive shaft is axially movable relative to the Adepterring susechlleßllch, the exlale Verechlebung the Output shaft upon rotation of the drive shaft relative to the system Adepterring output shaft a consequence of Actual connection of the drive shaft and the feed shaft of the drive shaft is the end point. According to the invention, the one connecting coupling realizes a rotetlonsverhlndernde connection between Qehluse and Adepterring whereby the operating state "advance", that is, an axial displacement of the output shaft against the Adepterring and the Qehluse, is made possible. The second connection coupling causes a Rotetlonsverhindernde connection between Adepterring and drive spindle

for the realization of the operating state "clamping", that is to say rotation of the adapter ring with drive splitter and

Coupling elements opposite the Gehluse. The switching functions are for dee switching "Vorechub-Spennen" by on the Qehluse appropriate electrical or

triggered electronic radio elements.

For the limit torque control switchover function "feed advance", the check function is preferably carried out

an electronic torque change or one of the coupling elements depending on the applied

Torque controlled, axial verschlebllchee push stick implemented. To override the torque from Coupling head on dae Spennelement the coupling head preferably has several spring loaded, both axially

mobile ice also includes rotatable driving pins, while the tensioning element has a star-shaped rib

Must have drive plate. When the driving pins hit in the operating state "advance" on the ribs of the driving disc, they are thus

against the spring force Retractable into the coupling body. In the operating state "Clamping", the drive pins are retained in the drive plate.
