Description

Die Erfindung betrifft eine weitere Ausgestaltung des Fahrgestells nach Patent 675 531, bei dem die Räder und die zugehörigen, ihre Federn tragenden Achsgestelle um einen Längsmittelträger schwingbar gelagert sind und ein an diesem Träger drehbar gelagerter Ausgleichhebel vorgesehen ist, der an den Enden gelenkig mit den Achsgestellen verbunden ist, so· daß der Fahrgestellrahmen immer in der Mittelstellung zu den Achsen gehalten wird. Zu diesem Zweck ist bei dem Fahrgestell nach dem Patent 675 531 derThe invention relates to a further embodiment of the chassis according to the patent 675 531, in which the wheels and the associated, their springs-bearing axle frames are mounted so they can swing around a longitudinal center beam and a compensating lever rotatably mounted on this carrier is provided, which is connected to the ends are articulated to the axle frames, so that the chassis frame is always held in the middle position to the axes. For this purpose is with the Chassis according to the patent 675 531 of the

Ausgleichhebel mit auf dem Längsmittelträger sitzenden und um letzteren drehbaren Achshülsen gelenkig verbunden. Bei dieser Anordnung ist ein Anschluß der Radachsen als unmittelbar am Längsträger angeordnete Schwinghalbachsen nicht möglich, weil die auf letzterem sitzenden Rohrhülsen im Wege sind. Die Schwinghalbachsen könnten nur an den Rohrhülsen selbst, nicht aber unmittelbar am Längsträger angebracht werden. Soll eine Achse z. B. durch mit Spiel durch den Längsträger hindurchgeführte SpannbolzenCompensating lever with axle sleeves seated on the longitudinal center beam and rotatable about the latter articulated. In this arrangement, a connection of the wheel axles is arranged directly on the side member Swinging half-axles not possible because the tubular sleeves sitting on the latter get in the way are. The oscillating half-axes could only be on the pipe sleeves themselves, but not directly be attached to the side member. If an axis z. B. through with play through the Clamping bolts passed through the side members

befestigt werden, so müssen hierzu in den Hülsen und im Längsträger längere Schlitze angebracht werden. Das ist aber umständlich und teuer.be attached, longer slots must be in the sleeves and in the side member be attached. But that is cumbersome and expensive.

Hiervon unterscheidet sich die vorliegende Erfindung im wesentlichen dadurch, daß der Ausgleichhebel unmittelbar mit den um den Längsmittelträger drehbaren Federstützen der Achsgestelle verbunden ist, wodurch die ίο Schwinghalbachsen unmittelbar am Längsmittelträger angeschlossen werden können. Die Anordnung ist daher im Aufbau einfacher und billiger und, da die besonderen Führungsschlitze an auf dem Längsträger sitzenden .Rohrhülsen wegfallen und die Schwinghalbachsen infolge der Verbindung des Ausgleichhebels mit den Federstützen unmittelbar am Längsmittelträger gelagert werden können, auch im Betrieb unempfindlicher und elastischer. Ferner bietet die Anordnung gemäß der Erfindung noch den Vorteil, daß der Längsmittelträger in seiner ganzen Länge frei ist, beispielsweise für die Anbringung von Traversen an beliebiger Stelle zur Abstützung eines Aufbaues. Auch ergibt die Anordnung nach der Erfindung eine geringere Beanspruchung der Kugelgelenke am Ausgleichhebel, da infolge des größeren Abstandes der Gelenkpunkte von der Drehachse der Achsgestelle die durch die Kugelgelenke zu übertragenden Kräfte erheblich verringert sind.The present invention differs from this essentially in that the Compensating lever directly with the spring supports which can be rotated around the longitudinal center beam the axle racks is connected, whereby the ίο swing half-axles directly on the longitudinal center beam can be connected. The arrangement is therefore simpler and cheaper in structure and, since the special guide slots are seated on the side member .Pipe sleeves omitted and the swinging half-axes due to the connection of the compensating lever can be stored directly on the longitudinal center beam with the spring supports, also less sensitive and more elastic during operation. Furthermore, the arrangement according to the invention offers the advantage that the longitudinal center support is free over its entire length is, for example, for the attachment of crossbars at any point for support of a structure. The arrangement according to the invention also results in less stress the ball joints on the compensating lever, because of the greater distance between the hinge points and the axis of rotation of the axle frames the forces to be transmitted through the ball joints are considerably reduced.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung an einem Anhänger dargestellt. In the drawing, an embodiment of the invention is shown on a trailer.

Mit dem z. B. rohrförmigen Längsmittelträger ι ist der Drehzapfen 2 für den Ausgleichhebel 3 fest verbunden. Der um den Zapfen 2 drehbare Ausgleichhebel 3, der gegenüber dem Zapfen 2 in der Höhe verschiebbar gelagert ist, ist seinerseits an seinen Enden durch Kugelgelenke 4 und 5 unmittelbar mit den Federstützen 6 und 7 der Achsgestelle 8 und 9 verbunden. Die Federstützen 6, 7 für die z. B. als Schraubenfedern 10, 11 ausgebildeten Druckfedern drehen sich mit ihrem unteren Ende um den Längsträger ι des Fahrgestells und werden mit ihren unteren halbkreisförmigen Gleitlagern 22 durch die federnden Spannschrauben 12 gegen den Längsträger 1 gepreßt, so daß sie auch in ihrer Lage verbleiben, wenn die Räder unbelastet sind. Die schwingenden Halbachsen 8, 9 sind durch halbkreisförmige Gleitlager 13, 14 an den Längsträger 1 angeschlossen und werden ebenfalls durch Spannbolzen 15, 16 gegen den Längsträger 1 gepreßt. With the z. B. tubular longitudinal center support ι is the pivot 2 for the compensation lever 3 firmly connected. The rotatable about the pin 2 compensation lever 3, the relative to the pin 2 is mounted displaceably in height, is in turn on his Ends by ball joints 4 and 5 directly with the spring supports 6 and 7 of the axle frames 8 and 9 connected. The spring supports 6, 7 for the z. B. designed as coil springs 10, 11 compression springs rotate with their lower end around the longitudinal member ι of the chassis and are with their lower semicircular slide bearings 22 by the resilient clamping screws 12 pressed against the longitudinal member 1 so that they also remain in their position when the wheels are unloaded. The swinging semi-axes 8, 9 are connected to the longitudinal beam 1 by semicircular plain bearings 13, 14 and are also pressed against the longitudinal beam 1 by clamping bolts 15, 16.

Das Anhängerfahrgestell ist mit stark gegeneinander verschwenkten Achsen gezeichnet, und zwar ist die Hinterachse nach rechts und die Vorderachse nach links um den Längsträger 1 verdreht. Der Längsträger 1 nimmt, wie die i\bbildung erkennen läßt, mit seinem senkrechten Drehzapfen 2 für den Ausgleichhebel 3 die Mittelstellung zwischen den Achsen bzw. zwischen den Federstützen 6, 7 der schwingenden Halbachsen ein.The trailer chassis is drawn with axles pivoted strongly against each other, the rear axle is rotated to the right and the front axle to the left around the longitudinal member 1. The side member 1 takes, as the image shows, with its vertical pivot 2 for the Compensation lever 3 the middle position between the axles or between the spring supports 6, 7 of the oscillating semi-axes.

Die Anordnung der Federstützen 6, 7 auf dem Längsträger 1 mittels halbkreisförmiger Gleitlager 22 von kegeligem Querschnitt unter Zwischenschaltung eines Bremsbelages in Verbindung mit der sie auf dem Längsträger gegen Abheben sichernden federnden Spannschraube 12 ist der Deutlichkeit halber im Schnitt besonders herausgezeichnet.The arrangement of the spring supports 6, 7 on the longitudinal member 1 by means of semicircular Plain bearing 22 of conical cross section with the interposition of a brake lining in connection with the resilient one that secures it on the side member against lifting For the sake of clarity, the clamping screw 12 is particularly drawn out in section.
