Die erreichten Vorteile sind darin zu sehen. daß eine Vorrichtung zum Verbinden eines Ladegerätes eines Kraftfahrzeuges mit einem Wechsel- oder Drehstromnetz eines Energieversorgungsunternehmens geschaffen ist. welche beim Parken des Kraftfahrzeuges im Stillstandsplatz gleichsam automatisch den Kupplungsvorgang ausführt, ohne das extrem hohe Anforderungen an die Positioniergenauigkeit des Kraftfahrzeuges gestellt werden. Infolge des Einsatzes der an sich bekannten induktiven Ankopplung wird praktisch auch Wartungsfreiheit erreicht. The advantages achieved can be seen in this. that a device for connecting a charger of a motor vehicle to an alternating or three-phase network of an energy supply company is created. which when parking the vehicle automatically executes the coupling process at a standstill without the made extremely high demands on the positioning accuracy of the motor vehicle will. As a result of the use of the known inductive coupling becomes practical also achieved freedom from maintenance.
Für die weitere Ausgestaltung bestehen im Rahmen der Erfindung mehrere Möglichkeiten. So sind nach einer bevorzugten Ausführungsform beide Transformatorteile gleichzeitig für Drehstrom- und Wechselstrombetrieb ausgelegt und die Wicklungen mit Zwischenanzapfungen versehen. Auf diese Weise ist primärseitig eine Anpassung des Transformators an das örtlich vorhandene Stromnetz und sekundärseitig mittels eines Umschalters eine stufige Wahl zwischen /3 oder 3/3 der Nennleistung möglich. Die federnde Lagerung der Transformatorteile kann sowohl unmittelbar als auch mittelbar beispielsweise durch federnde Aufhängung der Stoßstangen, die ohnehin im Zuge der Bestrebungen, die Sicherheit von Kraftfahrzeugen zu erhöhen, zu erwarten ist, und/oder durch federnde Befestigung der Ladeplanken am Stillstandsplatz verwirklicht werden. For the further development there are several within the scope of the invention Options. Thus, according to a preferred embodiment, both transformer parts Simultaneously designed for three-phase and alternating current operation and the windings provided with intermediate taps. In this way there is an adaptation on the primary side of the transformer to the local power grid and on the secondary side by means of a changeover switch, a step selection between / 3 or 3/3 of the nominal power is possible. The resilient mounting of the transformer parts can be both direct and indirect for example, through the spring suspension of the bumpers, which are anyway in the course of Efforts to increase the safety of motor vehicles can be expected, and / or can be realized by resilient fastening of the loading planks at the standstill area.
Unabhängig davon sollten dem Transformatorteil des Stillstandsplatzes optische Markierungen und/oder Bodenausnehmungen bzw. -erhöhungen zur Positionierung für Räder des Kraftfahrzeuges zugeordnet sein. Regardless of this, the transformer part of the standstill should be optical markings and / or floor recesses or elevations for positioning be assigned for wheels of the motor vehicle.
Darüber hinaus kann es empfehlenswert sein, den Tranformatorteilen, wie es an sich aus US-PS 34 14 796 bekannt ist, eine Meß- und Anzeigeeinrichtung für den Ankupplungszustand zuzuordnen, mit welcller der Führer des Kraftfahrzeuges bei unzureichendem Ankupplungszustand zur Wiederholung des Kuppelmanövers aufgefordert werden kann. Zur Messung des Ankupplungszustandes eignet sich insbesondere ein mit dem Transformatorteil des Kraftfahrzeuges verbundenes Spannungsrelais zur Überwachung der vom Transformatorteil des Stillstandsplatzes im Transformatorteil des Kraftfahrzeuges induzierten Leerlaufspannung.In addition, it can be recommended to use the transformer parts, as is known per se from US-PS 34 14 796, a measuring and display device for the coupling state to be assigned, with welcller the driver of the motor vehicle requested to repeat the coupling maneuver if the coupling condition is inadequate can be.

Dazu sind die beiden Transformatorteile gegebenenfalls mit zusätzlichen Signalübertragungswicklungen zu versehen, welche auch zur Übermittlung von Signalen ati am Stillstandsplatz angeordnete Zählgeräte herangezogen werden können. An Stelle der zusätzlichen Signalübertragungswicklungen ist es aber auch möglich, zum gleichen Zweck die die Leistung übertra- genden Primär- und Sekundärwicklungen des Transformators zu verwenden. Die selbsttätige Ein-/Ausschalteinrichtung kann beispielsweise aus einer Beschaltung mit elektrischen Bauelementen bestehen, die unterschiedliche Spannungen im gekuppelten und entkuppelten Zustand auswertet, oder aus einem Schaltschütz, das von Änderungen der Transformatorimpedanz angeregt wird.
