Abstract

The damping system is intended for an articulated motor coach (1,2) and comprises dampers (4), which are arranged to either side of the longitudinal centre line between the facing ends of the towing (1) and trailing coach section (2) to limit the relative angle between these sections. The dampers, which may be arranged at the front face (41) of the trailing section, consist of a piston-cylinder unit (9,8) whose piston rod (12) carries a stop (6) with a rubber buffer (5). The piston separates a low-pressure chamber (16) at the buffer side from a pressure chamber (13) containing a spring (10) on the other side, the two chambers being connected via a throttle (14).

Description

Knickwinkelanschlag für Gelenkbusse Articulated angle stop for articulated buses

Die Erfindung betrifft einen neuartigen Knickwinkelanschlag für Gelenkbusse, insbesondere solche, die keine besonderen Vorrichtungen zur Steuerung des Knickwinkels aufweisen.The invention relates to a novel articulation angle stop for articulated buses, especially those that do not have any special devices for controlling the articulation angle exhibit.

Bei derartigen Gelenkbussen wird der Knickwinkel durch Anschlag von lIetall-Gummi-Elementen begrenzt. Beim Anschlagen können recht harte Schläge auf treten, die für die Fahrgäste unangenehm sind und auf die Dauer auch die Haltbarkeit des Fahrzeugs beeinträchtigen.In articulated buses of this type, the articulation angle is set by a stop of Metal-rubber elements limited. When striking, you can get quite hard blows which are uncomfortable for the passengers and in the long run also the durability affect the vehicle.

Es ist deshalb die Aufgabe der Erfindung, eine Dämpfungsvorrichtung aufzuzeigen, welche diese Stöße weich auffängt.It is therefore the object of the invention to provide a damping device to show which softly absorbs these shocks.

Diese Aufgabe wird durch die kennzeichnenden Merkmale des Patentanspruchs in neuartiger Weise gelöst.This object is achieved by the characterizing features of the patent claim solved in a new way.

Die Erfindung wird anhand der Zeichnung mit einem Ausführungsbeispiel erläutert; dabei zeigt Fig. 1 einen mit der Erfindung ausgerüsteten Gelenkbus in Draufsicht, Fig. 2 die Erfindung in vergrößerter Darstellung und Fig. 3 die auftretenden Feder- und Dämpfungskennlinien.The invention is based on the drawing with an exemplary embodiment explained; 1 shows an articulated bus equipped with the invention in FIG Top view, FIG. 2 the invention in an enlarged view and FIG. 3 the occurring Spring and damping characteristics.

Gemäß Fig. 1 ist der Vorderwagen 1 eines Gelenkbusses über ein Gelenk 3 mit seinem Nachläufer 2 verbunden. Der mögliche Knickwinkel zwischen Vorderwagen und Nachläufer ist durch je ein Dämpfungsglied 4 an jeder Anschlagfläche 41 und 4r begrenzt.According to Fig. 1, the front end 1 of an articulated bus is via a joint 3 connected to its trailer 2. The possible articulation angle between the front end and trailer is through a damping member 4 on each stop surface 41 and 4r limited.

Gemäß Fig. 2 besteht dieses aus einem am Nachläufer befestigten Kolbenzylinderelement 8, 9. Dabei ist ein Gummipuffer 5 auf einer metallischen Zwischenscheibe 6 und einem Gummipuffer 7 befestigt, der mit der Kolbenstange 12 eines Kolbens 9 fest verbunden ist. Dieser ist in einem Zylinder 8 gleitbar gelagert.According to FIG. 2, this consists of a piston-cylinder element attached to the trailer 8, 9. Here, a rubber buffer 5 is on a metallic washer 6 and one Rubber buffer 7 attached, which is firmly connected to the piston rod 12 of a piston 9 is. This is slidably mounted in a cylinder 8.

Der Kolben 9 trennt zwei ZylinderkamrL1ern voneinander, nämlich eine Niederdruckkammer 16 auf der Seite der Gummipuffer und eine Druckkammer 13 auf der Gegenseite, in der sich eine Druckfeder 10 befindet. Die beiden Kammern stehen über eine hydraulische Drosselleitung, die eine Verstelldrossel 14 und ein dazu parallelgeschaltetes Rückschlagventil 15 enthält, miteinander in Verbindung.The piston 9 separates two cylinder chambers from one another, namely one Low pressure chamber 16 on the side of the rubber buffer and a pressure chamber 13 on the Opposite side, in which a compression spring 10 is located. The two chambers protrude a hydraulic throttle line, an adjusting throttle 14 and a parallel connected thereto Check valve 15 contains, in communication with each other.
