Description

Das Patent 922 810 betrifft eine Federung für Fahrzeuge, insbesondere Straßenfahrzeuge, mittels gleichzeitiger Abfederung durch Luft- und mechanische Federkörper als Federungsmittel, bei welcher die verschiedenartigen Federungsmittel gleichzeitig voneinander unterschiedliche Federungswege durchlaufen, der Druck der Räder hydraulisch auf die diesen zugeordneten verschiedenartigen Federungsmittel gemeinsam übertragen wird- und bei welcher The patent 922 810 relates to a suspension for vehicles, in particular road vehicles, by means of simultaneous cushioning by air and mechanical spring bodies as suspension means, in which the different types of suspension means run through suspension paths that are different from one another at the same time, the pressure of the wheels is transmitted hydraulically to the various suspension means associated with them - and at which

ίο ein Steuerorgan, welches den Zu- und Ablauf der Übertragungsflüssigkeit in Abhängigkeit von der Höhenlage des Wagenkastens auf Einhaltung gleichbleibender Wagenkastenhöhe steuert, vorgesehen ist. Die Anordnung von mechanischen Übertragungsgestängen zur Betätigung des Steuerorgans ist aus baulichen Gründen nicht immer durchführbar. Die Erfindung schlägt deshalb vor, das Steuerorgan über einen Kolben od. dgl. zu betätigen, der in die Druckflüssigkeitsübertragungsleitung zwischen Rad und Federung eingeschaltet ist. Bei Abfederung einer Gruppe von Rädern arbeiten die Räder erfindungsgemäß gemeinsam auf den Kolben, wodurch der Kolben gewissermaßen die Stellung der einzelnen Räder ausmittelt.ίο a control organ that controls the inflow and outflow of Transmission fluid depending on the height of the car body to maintain constant Car body height controls is provided. The arrangement of mechanical transmission rods to operate the control member is not always feasible for structural reasons. the Invention therefore proposes to operate the control member via a piston or the like, which is in the Hydraulic fluid transmission line between wheel and suspension is switched on. With cushioning a group of wheels, the wheels work together on the piston according to the invention, whereby the piston to a certain extent averages out the position of the individual wheels.

Zur Erläuterung ist in Fig. 1 schematisch die Abfederung eines Rades gemäß der Erfindung dargestellt. Die Fig. 2 zeigt schematisch' die Abfederung einer Gruppe von Rädern.For explanation, the suspension of a wheel according to the invention is shown schematically in FIG. 1. Fig. 2 shows schematically 'the suspension of a group of wheels.

Mit ι ist der Wagenkasten bezeichnet. 2 ist das Fahrzeugrad. Die Bewegungen des Fahrzeugrades 2 sollen auf die Federtöpfe 6 und 7 übertragen werden, von denen der eine Federungstopf 6 als Federungsmittel ein Luftpolster oberhalb der Kolbenscheibe aufweist, während der andere Federungstopf 7 die Festkörperfederung enthält, die bei ■dem Ausführungsbeispiel als Tellerfederung ausgebildet ist. Die Übertragung erfolgt über den Kolben 3, der in einem Zylinder 4 arbeitet, und die Druckflüssigkeitsleitung 5. Für die Zu- und Ableitung von Druckflüssigkeit ist eine Pumpe 11 vorgesehen, die mit den Leitungen 8 und 9 an die Druckflüssigkeitsübertragungsleitung 5 angeschlossen ist. Der Schieber 10 als Steuerorgan steuert Zu- und Ablauf der Druckflüssigkeit, und zwar in Abhängigkeit von der Wagenkastenhöhe. Während bei dem Ausführungsbeispiel nach dem Patent 922 810 der Schieber 10 mittels eines Übertragungsgestänges bewegt wird, wird bei der vorliegenden. Anmeldung der Schieber 10 durch den Kolben 13 bewegt. Dieser Kolben 13 arbeitet in dem Arbeitszylinder 12, ist also als bewegliche trennende Wandung in die Druckflüssigkeitsübertragungsleitung 5 zwischen Rad und Federung eingeschaltet.The car body is designated with ι. 2 is the vehicle wheel. The movements of the vehicle wheel 2 are to be transferred to the spring cups 6 and 7 be, of which a suspension pot 6 as a suspension means an air cushion above the Has piston disc, while the other suspension pot 7 contains the solid-state suspension, which at ■ the embodiment is designed as a disc suspension. The transmission takes place via the piston 3, which works in a cylinder 4, and the hydraulic fluid line 5. For the supply and discharge of hydraulic fluid, a pump 11 is provided, which with lines 8 and 9 to the hydraulic fluid transmission line 5 is connected. The slide 10 as a control member controls supply and Drainage of the hydraulic fluid, depending on the car body height. While at the embodiment according to patent 922 810 the slide 10 by means of a transmission linkage is moved is in the present. Registration of the slide 10 moved by the piston 13. This piston 13 works in the working cylinder 12, so it is in the form of a movable separating wall the hydraulic fluid transmission line 5 switched on between the wheel and the suspension.

Sind mehrere Räder gleichzeitig abzufedern, so wird jedes Rad mit einem eigenen Arbeitszylinder auf den Zylinder 12 geschaltet (Fig. 2). Hierdurch wird die Steuerung der einzelnen Räder der Gruppe von mehreren Rädern gewissermaßen ausgemittelt. Derartige Anordnungen sind beispielsweise gedacht für mehrachsige Drehgestelle von Schienenfahrzeugen. If several wheels are to be cushioned at the same time, each wheel has its own working cylinder switched to the cylinder 12 (Fig. 2). This will control the individual wheels of the group averaged out, as it were, by several wheels. Such arrangements are intended for example for multi-axle bogies of rail vehicles.
