Description

Schnellschaltgerät für elektromagnetisch betätigte Reibungskupplungen oder -bremsen Es ist bekannt, bei elektromagnetisch betätigten Reibungskupplungen oder -bremsen den zeitlichen Zwischenraum zwischen der Impulsgabe und dem Anrücken der Ankerscheibe und damit dem Ansprechen der Kupplung bzw. Bremse durch Überhähung der Erregerspannung zu verkürzen und die zeitgerechte Verminderung der Spannung auf die zulässige Magnetspulenspannung nach dem Ansprechen der Kupplung bzw. Bremse durch ein im Erregerstromkreis liegendes Schnellschaltgerät zu steuern.High-speed switching device for electromagnetically operated friction clutches or brakes It is known in electromagnetically operated friction clutches or -brake the time gap between the impulse and the approach the armature disk and thus the response of the clutch or brake due to overheating to shorten the excitation voltage and the timely reduction of the voltage to the permissible magnet coil voltage after the clutch or brake has responded controlled by a high-speed switching device in the excitation circuit.

Diese bekannten Schnellschaltgeräte bestehen im wesentlichen aus einem unter Berücksichtigung der Stromaufnahme durch die Magnetspule auf die Spulen- und die Netzspannung abgestimmten festen Widerstand und einem Verzögerungsrelais oder einem Kleinschütz, das diesen Widerstand für einen kurzen Zeitraum kurzschließt und die volle verfügbare Netzspannung an die Magnetspule gelangen läßt. In Abhängigkeit von dem Verhältnis der Netzspannung zur Magnetspulenspannung läßt sich mit einem solchen Schnellschaltgerät die Ansprechzeit der Kupplung bzw. Bremse erheblich verkürzen, ohne eine Anpassung der Spule an die höhere Netzspannung vornehmen zu müssen, da die volle Netzspannung nur für sehr kurze Zeit an der Spule liegt.These known high-speed switching devices essentially consist of one taking into account the current consumption by the magnetic coil on the coil and the mains voltage matched fixed resistor and a delay relay or a miniature contactor that short-circuits this resistor for a short period of time and allows the full available mains voltage to reach the solenoid. Dependent on of the ratio of the mains voltage to the magnet coil voltage can be determined with a such a high-speed switching device considerably shorten the response time of the clutch or brake, without having to adapt the coil to the higher line voltage, there the full mains voltage is only applied to the coil for a very short time.

Der Aufwand zur Erzielung dieser verkürzten Ansprechzeit ist jedoch infolge der Verwendung eines Verzögerungsrelais und eines Widerstandes in dem Schnellschaltgerät ziemlich hoch. Außerdem gibt das Verzögerungsrelais leicht Anlaß zu Störungen, und das gesamte Schnellschaltgerät bedarf einer stetigen Überwachung.However, the effort to achieve this reduced response time is due to the use of a delay relay and resistor in the high speed switch quite high. In addition, the delay relay easily gives rise to malfunctions, and the entire high-speed switching device requires constant monitoring.

Durch die Erfindung werden diese Nachteile vermieden und ein Schnellschaltgerät geschaffen, das aus handelsüblichen, billigen Teilen besteht, einen selbst für einen Nichtfachmann leicht zu übersehenden und zu begreifenden schaltungstechnischen Aufbau besitzt und fast die gleiche Wirkung wie die bekannten Schnellschaltgeräte ergibt.The invention avoids these disadvantages and provides a high-speed switching device made of off-the-shelf, cheap parts, one for one Circuitry structure easy to overlook and understand for non-experts and has almost the same effect as the known high-speed switching devices.

Bekannt ist bereits, temperaturabhängige Widerstände mit positiven Temperaturkoeffizienten in den Erregerstromkreis von zu steuernden elektrischen Maschinen zu erhalten.It is already known, temperature-dependent resistors with positive Temperature coefficients in the excitation circuit of the electrical to be controlled Machines to get.

Gemäß der Erfindung dient als Widerstand eine Glühlampe mit Metallwendeln, z. B. eine der handelsüblichen Automobilscheinwerferlampen oder ein aus mehreren solcher Glühlampen in Parallel- und/oder Reihenschaltung bestehender Glühlampensatz, der im Hauptschluß in den Erregerstromkreis der Magnetspule eingeschaltet ist.According to the invention, an incandescent lamp with metal filaments serves as a resistor, z. B. one of the commercially available automobile headlight lamps or one of several such incandescent lamps in parallel and / or series connection existing incandescent lamp set, which is switched on in the main circuit in the excitation circuit of the solenoid.

Es wird bei dem Erfindungsgegenstand die bekannte Eigenschaft der Metallwendel mit zunehmender Temperatur ihren Widerstand zu steigern, ausgenutzt. Beim Einschalten des Erregerstromes läßt der geringe Widerstand der noch kalten Metallwendel eine große, fast die volle Netzspannung erreichende Spannung an der Magnetspule zu. Hierdurch wird ein schnelles Ansprechen der Kupplung bzw. Bremse erreicht. Der schnell mit der Erwärmung zunehmende Widerstand der Metallwendel drosselt dann die Spannung auf das erforderliche, durch den Warmwiderstand der Metallwendel bestimmte Maß. Bei der Auswahl von Glühlampen mit solchen Werten, die zwischen der vorhandenen Netzspannung und der erforderlichen Spulenspannung vermitteln, kann nach der anfänglichen Übererregung die Spule im Betriebszustand nicht weiter übererregt werden, so daß ihre Lebensdauer nicht gefährdet ist.In the subject matter of the invention, the known property of Metal helix used to increase its resistance with increasing temperature. When the excitation current is switched on, the low resistance leaves the still cold Metal helix a large voltage reaching almost the full line voltage at the Solenoid closed. This enables the clutch or brake to respond quickly achieved. The resistance of the metal coil, which increases rapidly with heating, throttles then the voltage to the required level, through the hot resistance of the metal coil certain measure. When choosing light bulbs with values between the convey the existing mains voltage and the required coil voltage after the initial overexcitation, the coil is no longer overexcited in the operating state so that their service life is not endangered.
