Description

Die bekannte Zangenmaulkupplung mit unter Federdruck stehender Verschlußhülse hat den Nachteil, daß das Eindringen von Schmutz in Hohlräume der verdeckt liegenden Federn das sichere Arbeiten der Kupplung verhindert. Für das Auslösen der Kupplung im Stand fehlt ferner ein einfaches Auslösemittel von Hand.The well-known jaw coupling with the locking sleeve under spring pressure has the disadvantage that the penetration of dirt into cavities of the concealed Springs prevent the clutch from working safely. For releasing the clutch A simple manual release mechanism is also missing in the stand.

Diese Nachteile vermeidet die Erfindung.The invention avoids these disadvantages.

Abb. I zeigt die Kupplung hinter dem Zangenmaul im Schnitt; Abb. 2 zeigt die Draufsicht auf Abb. I; Abb. 3 zeigt einen Schnitt nach Linie A-B der Abb. I.Fig. I shows the coupling behind the jaws in section; Fig. 2 shows the top view of Fig. I; Fig. 3 shows a section along line A-B of Fig. I.

Die Verschlußhülse 9 und das zugehörige Mittelstück I4 werden nach der Erfindung ohne Rillen und Hohlräume gestaltet. Die Federn 7 sind auf außenliegenden Verbindungsstangen Io angeordnet, die durch eine Traverse II miteinander verbunden sind. Der Teil des Mittelstückes I4, auf dem die Verschlußhülse 9 gleitet, wird durch einen leicht abnehmbaren Gummischutz 26, der zwischen der Verschlußhülse 9 und der Befestigungsplatte I2 des Mittelstückes I4 angeordnet ist, geschützt.The locking sleeve 9 and the associated center piece I4 are after of the invention designed without grooves and cavities. The springs 7 are on the outside Connecting rods Io are arranged, which are connected to one another by a traverse II are. The part of the middle piece I4 on which the locking sleeve 9 slides is by an easily removable rubber protector 26 between the locking sleeve 9 and the mounting plate I2 of the middle piece I4 is protected.

Die axiale Drehbarkeit der Kupplung muß in einem bestimmten Maße möglich sein. Dazu ist auf dem zylindrischen Teil 4 des festen Zangenteiles ein Stift 23 angebracht, der in eine segmentartige Ausnehmung 24 (Abb. 3) an der Stirnfläche des Mittelstückes I4 eingreift.The axial rotatability of the coupling must be possible to a certain extent be. For this purpose, a pin 23 is on the cylindrical part 4 of the fixed pliers part attached, which is in a segment-like recess 24 (Fig. 3) on the end face of the middle piece I4 engages.

Um eine Handbetätigung der Verschlußhülse an Ort und Stelle zu ermöglichen, ist ein Haltearm 2I an der Befestigungsplatte I2 angebracht, der über der Verschlußhülse 9 ein Lager für einen zweiarmigen Hebel 22 trägt. Dieser Hebel umfaßt mit seinem unteren gabelförmigen Teil 22a die Verschlußhülse 9 in der Mitte. Beim Zurücklegen des Hebels 22 wird die Verschlußhülse 9 zurückgezogen und die Kupplung geöffnet.To enable manual actuation of the locking sleeve on the spot, A holding arm 2I is attached to the mounting plate I2, which is above the locking sleeve 9 a bearing for a two-armed lever 22 carries. This lever includes with his lower fork-shaped part 22a the locking sleeve 9 in the middle. When putting back of the lever 22, the locking sleeve 9 is withdrawn and the coupling is opened.

Zur Anbringung der Vorrichtung an einem Teil der Quertraverse des Zugfahrzeuges ist hinter der Befestigungsplatte I2 eine zweite Befestigungsplatte 25 lose aufgesetzt.To attach the device to a part of the cross member of the The towing vehicle is a second mounting plate behind the mounting plate I2 25 loosely attached.
