Stellantrieb mit FederrückzugActuator with spring return

In bestimmten Anwendungen ist vorgeschrieben, daß nach motorischer Betätigung einer Luft- bzw. Abgasklappe die Rückstellung durch Feder erfolgen muss. Dies wird bisher hauptsächlich dadurch bewerkstelligt, daß ein Spaltpolmotor über ein Getriebe die Klappe in eine definierte Stellung bringt. Der Motor bleibt solange unter Spannung, bis die Klappe wieder in die Ausgangsstellung gebracht werden soll. Der Motor wird spannungslos und die Feder übernimmt die Rückstellung der Klappe.In certain applications it is specified that after motor actuation of an air or exhaust flap, the flap must be reset by a spring. To date, this has mainly been achieved by a shaded-pole motor using a gear to move the flap into a defined position. The motor remains under voltage until the flap is to be returned to its original position. The motor is de-energized and the spring takes over the reset of the flap.

Diese Version hat den Nachteil, daß beim Schliessen über einen Federrückzug das komplette Getriebe einschliesslich des Motor-Rotors mitgezogen wird, das zu einer erheblichen mechanischen Belastung des Getriebes führt, was wiederum Undefinierte Ausfälle während der Lebensdauer zur Folge haben kann, vor allen Dingen auch bedingt durch die Masse-Trägheit des Motors. Zur Reduzierung dieses Effektes wird in der Regel eine Fliehkraftbremse eingesetzt.This version has the disadvantage that when closing via a spring return, the entire gear box including the motor rotor is pulled along, which leads to a considerable mechanical load on the gear box, which in turn can result in undefined failures during the service life, especially due to the mass inertia of the motor. A centrifugal brake is usually used to reduce this effect.

Ursachen für die vorerwähnten Ausfälle sind Nichterreichen der Ausgangsstellung durch erhöhte Reibungsverluste und Verklemmen durch Abrieb. Unsere Konzeption schließt vorgenannte Nachteile aus und hat den Vorteil, daß während des Rücklaufes nur noch eine sehr geringe mechanische Belastung des Getriebes erfolgt und dadurch eine lange, sichere Funktion gewährleistet ist. Dies wird erreicht durch Auskuppeln des Getriebes während der Rückstellung, vorzugsweise nahe der Endstufe, um die Belastung des Getriebes so gering wie möglich zu halten und kurze Schließzeiten zu erreichen.The causes of the aforementioned failures are failure to reach the starting position due to increased friction losses and jamming due to abrasion. Our design eliminates the aforementioned disadvantages and has the advantage that only a very low mechanical load is placed on the gear during the return run, thus ensuring long, reliable operation . This is achieved by disengaging the gear during the return, preferably close to the final stage, in order to keep the load on the gear as low as possible and to achieve short closing times.

Dadurch gekennzeichnet, daß aus Kostengründen ein Synchronmotor (1) verwendet wird, der über einen Mikroschalter (3) in der Endstellung abgeschaltet wird. Der beim Einschalten des Motors bestromte Hubmagnet bewirkt ein Einrasten der Kupplung (5).Characterized in that, for cost reasons, a synchronous motor (1) is used, which is switched off in the end position via a microswitch (3). The lifting magnet, which is energized when the motor is switched on, causes the clutch (5) to engage. Dadurch gekennzeichnet, daß bei Signal "Klappe Ausgangsstellung" die Spannung zum Hubmagnet unterbrochen wird. Die Druckfeder (6) der Kupplung bewirkt das Auskuppeln des Getriebes, wodurch die Rückstellung durch eine Rückzugsfeder ermöglicht wird.Characterized in that when the "flap initial position" signal is given, the voltage to the lifting magnet is interrupted. The pressure spring (6) of the clutch causes the gear to be disengaged, which enables the return by a return spring. W. Sruner GmbH - ReiaisiabrikW.
