Abstract

The steering pivot of the rear unit driven articulated vehicle is flanked by spring loaded cables drives which monitor the angle of the two units and compares this angle with the steering setting. The control unit operates selective brakes on either side of the rear unit. The system provides additional stability for the articulated vehicle and prevents it from jackknifing in tight corners.

Description

Nachläufer-Steuerung an einem Gelenkzug Follower control on an articulated train

An einem Gelenkzug, z. B. einem Gelenkbus, vorwiegend mit Heckantrieb am Nachläufer tritt beim Einleiten einer Kurvenfahrt die unangenehme Erscheinung auf, daß der zwischen Vorderwagen und Nachläufer sich einstellende Knickwinkel durch den von den Rädern des Nachläufers ausgehenden Schub noch weiter vergrößert wird. Dieses Fehlverhalten kann insbesondere dann eintreten, wenn zwischen den Reifen der Mittelachse und der Straße eine geringere Reibung vorhanden ist als zwischen den Reifen des Nachläufers und der Straße.On an articulated train, e.g. B. an articulated bus, mainly with rear-wheel drive the unpleasant phenomenon occurs on the trailer when initiating a cornering on that the angle of articulation established between the front end and the rear end the thrust emanating from the wheels of the trailer is increased even further. This malfunction can occur especially when between the tires there is less friction between the central axis and the road than between the tires of the trailer and the road.

Es ist Aufgabe der Erfindung, diesem Fehlverhalten durch geeignete Maßnahmen entgegenzuwirken, also eine Einrichtung aufzuzeigen, die dem fehlerhaften Vergrößern des Knickwinkels bei Kurvenfahrt entgegenwirkt oder dieses überhaupt ausschaltet Diese Aufgabe wird mit den kennzeichnenden Merkmalen des Anspruchs gelöst.It is the object of the invention to remedy this malfunction by means of suitable To counteract measures, so to show a facility that the faulty Increasing the articulation angle counteracts when cornering or this at all turns off This task is done with the distinguishing features of the claim solved.

Die Erfindung wird nun an Hand der Zeichnung mit einem Ausführungsbeispiel erläutert, die einen Gelenkzug schematisch in Draufsicht darstellt. Dabei zeigt Fig. 1 die Geradeausfahrt und Fig. 2 eine Linkskurvenfahrt.The invention is now based on the drawing with an embodiment explained, which represents an articulated train schematically in plan view. It shows 1 shows the straight-ahead drive and FIG. 2 shows a left-hand curve.

Der Vorderwagen 1 des Gelenkzugs ist mit seinem Nachläufer 2 über einen Drehkranz 3 verbunden. An dessen linker und rechter Seite ist je ein Kontaktstück 4 bzw. 4 angebracht, das 1 r gegen die Kraft je einer Feder 5 durch einen Seilzug 61 bzw. 6r entsprechend dem Lenkeinschlag des Vorderwagens 1 auf einer Kreisbahn zurückgezogen wird. Mit diesen Kontaktstücken zusammenwirkende Kontaktstücke 71 bzw. 7 sind r fest an der Drehscheibe 3 angebracht. über elektrische Leitungen 81 bzw. 8r wird eine Verbindung zu je einer Bremseinrichtung 91 bzw. 9r der Nachläuferräder 101 bzw. 10r hergestellt. Diese Bremseinrichtungen sollen vorzugsweise mit Blockierschutz ausgerüstet sein.The front carriage 1 of the articulated train is with its trailer 2 over a turntable 3 connected. There is a contact piece each on its left and right side 4 or 4 attached, the 1 r against the force of a spring 5 by a cable 61 or 6r corresponding to the steering angle of the front end 1 on a circular path is withdrawn. Contact pieces 71 cooperating with these contact pieces and 7 are r firmly attached to the turntable 3. via electrical lines 81 or 8r is a connection to a respective braking device 91 or 9r of the trailing wheels 101 and 10r, respectively. These braking devices should preferably have anti-lock protection be equipped.

Die Wirkungsweise der erfindungsgemäßen Einrichtung ist folgende: Bei einem Lenkeinschlag zieht der entsprechende Seilzug 61 oder 6r sein Kontaktstück 41 bzw.The operation of the device according to the invention is as follows: When the steering wheel is turned, the corresponding cable 61 or 6r pulls its contact piece 41 or

4r zurück Wegen des bei Kurvenfahrt eintretenden Knickwinkels zwischen Vorderwagen und Nachläufer folgt das kurveninnere feste Kontaktstück 71 oder 7r dem jeweiligen beweglichen Kontaktstück 41 bzw. 4r nach. Falls der Nachläufer noch weiter auszuschwenken versucht, als vom~Lenkeinschlag vorgegeben, so kommen die entsprechenden Kontaktstücke 41' 7 bzw. 4 , 7r in Berührung miteinander. Hierr r durch fließt in der entsprechenden Leitung 81 bzw. 8 r Strom, so daß die Bremseinrichtung 91 bzw. 9 am kurvenr inneren Rad 101 bzw. 10r eine gewisse Bremsung durchführt; dadurch wird ein um das gebremste Rad wirksames ausgleichendes Drehmoment M1 bzw. Mr hervorgerufen und damit der Knickwinkel begrenzt.4r back Because of the articulation angle between The fixed contact piece 71 or 7r on the inside of the curve follows the front end and the trailer according to the respective movable contact piece 41 or 4r. If the trailer is still If you try to swing out further than specified by the steering angle, they come corresponding contact pieces 41 '7 or 4, 7r in contact with one another. Here r through flows in the corresponding line 81 or 8 r current, so that the braking device 91 or 9 performs a certain braking on the curve inner wheel 101 or 10r; as a result, a compensating torque M1 resp. Mr caused and thus the articulation angle is limited.
