Description

DEUTSCHESGERMAN

Die Erfindung bezieht sich auf eine unabhängige Radaufhängung gelenkter Räder von Kraftfahrzeugen an Längslenkern, bei welchen die Radträger mittels Tragzapfen am Ende der Lenker gelagert sind, derart, daß die Radträger oder die mit diesen verbündenen Teile durch ein Gewindedoppelgelenk an den Lenkern befestigt sind, welches durch einen Gewindebolzen und den Tragzapfen, der im Gewindebodzenträger gelagert ist, gebildet wird, nach Patent 943930.The invention relates to an independent wheel suspension of the steered wheels of motor vehicles on trailing arms, in which the wheel carriers are mounted by means of trunnions at the end of the arm, in such a way, that the wheel carriers or the parts connected to them by a threaded double joint on the handlebars are attached, which by a threaded bolt and the support pin, which is in the threaded body is stored, is formed, according to patent 943930.

Nach dem Hauptpatent sind die Radträger durch ein Gewindedoppelgelenk an den Lenkern befestigt. Dadurch werden die bei der Bearbeitung auftretenden Ungenauigkeiten ausgeglichen und die Bildung von Spannungen in den Lagern der Tragzapfen vermieden. Diese Wirkung wird noch erhöht und außerdem eine gewisse Nachgiebigkeit und Geräuschdämpfung erzielt, wenn nach der Erfindung der Gewindebolzen unter Zwischenschaltung einer elastischen Einlage im Unabhängige Radaufhängung

According to the main patent, the wheel carriers are attached to the handlebars by means of a double threaded joint. In this way, the inaccuracies that occur during machining are compensated for and the formation of stresses in the bearings of the trunnions is avoided. This effect is further increased and a certain flexibility and noise dampening are achieved if, according to the invention, the threaded bolt with the interposition of an elastic insert in the independent wheel suspension

Es ist bei einer Radaufhängung mit Querlenkern bekannt, die Kugelzapfen der oberen Querlenker in einer zweiteiligen Kugelschale zu lagern. Von dieser Schale ist die untere Hälfte aus Metall und die obere aus elastischem Material hergestellt. Durch diese elastische Halbschale wird eine einseitige Dämpfung des Radträgers erreicht, wobei beim Zurückschwingen desselben nach wie vor harte Schläge durch unmittelbare Berührung von Metall mit Metall auftreten. Dieser Umstand bewirkt einen übermäßigen Verschleiß des Lagers. Außerdem wird die Kugel· durch Reibung an der Kante der unteren metallenen Lagerschale beschädigt und bedarf laufend einer teuren Nacharbeit.It is known in a wheel suspension with wishbones, the ball studs of the upper wishbones in to store a two-part spherical shell. The lower half of this bowl is made of metal and the upper half made of elastic material. This elastic half-shell creates a one-sided damping of the wheel carrier reached, while swinging back the same as before hard hits by immediate Contact of metal with metal can occur. This fact causes excessive wear of the camp. In addition, the ball is · by friction on the edge of the lower metal bearing shell damaged and constantly requires expensive rework.

Die Ausführung gemäß der Erfindung bewirkt eine allseitige Dämpfung der Schwingungen, die in Verbindung mit der beweglichen Befestigung des Radträgers an den Lenkern eine einfache und vorteilhafte Radaufhängung ergibt. Die elastische Einlage besteht aus einer Hülse, in welcher ein Ring aus Gummi oder technisch gleichwertigem Werkstoff einvulkanisiert ist. Für die Teile der Lagerung können stranggepreßte Stücke verwendet werden, so daß die Herstellung des Lagers einfach und billig ist.The execution according to the invention causes an all-round damping of the vibrations, which in connection with the movable attachment of the wheel carrier to the handlebars a simple and advantageous one Suspension results. The elastic insert consists of a sleeve in which a ring made of rubber or technically equivalent material is vulcanized into it. For the parts of the storage can be extruded Pieces are used so that the manufacture of the bearing is simple and inexpensive.

In der Zeichnung ist eine beispielsweise Ausfuhr rungsform der Erfindung bei einer Radaufhängung mit Längslenkern veranschaulicht. Es zeigtIn the drawing is an example of execution of the invention in a wheel suspension illustrated with trailing arms. It shows

Fig. 1 einen Schnitt durch das im Radträger gelagerte Doppelgelenk für den Tragzapfen eines der Längslenker undFig. 1 is a section through the double joint mounted in the wheel carrier for the support pin of one of the Trailing arm and

Fig. 2 einen Schnitt nach der Linie II-II der Fig. 1. Der Längslenker 1 ist in einem nicht dargestellten Vorderachskörper des Kraftfahrzeuges drehbar gelagert und weist an seinem frei schwingenden Ende einen Lagerarm 2 auf. Der Lagerarm dient zur Aufnahme eines Tragzapfens 3, welcher durch Schrauben 4 in dem Lagerarm eingespannt ist. Das freie Ende 5 des Tragzapfens 3 ist mit Gewinde versehen. Das Gegenstück hierzu bildet ein Bolzen 6, welcher eine Bohrung 7 aufweist, die mit Innengewinde versehen ist. Der Bolzen 6 ist im Radträger 8 gelagert, welcher gleichzeitig den Achsschenkelbolzen 9 aufnimmt. Schwenkbar um den Achsschenkelbolzen 9 ist der ein lenkbares Rad tragende Achsschenkel 10 angeordnet. FIG. 2 shows a section along the line II-II in FIG. 1. The trailing arm 1 is rotatably mounted in a front axle body, not shown, of the motor vehicle and has a bearing arm 2 at its freely oscillating end. The bearing arm is used for recording a support pin 3, which is clamped by screws 4 in the bearing arm. The free End 5 of the support pin 3 is provided with a thread. The counterpart to this is a bolt 6, which has a bore 7 which is provided with an internal thread. The bolt 6 is mounted in the wheel carrier 8, which at the same time receives the kingpin 9. Can be pivoted about the kingpin 9 the steering knuckle 10 carrying a steerable wheel is arranged.

Die Lagerung des den Tragzapfen 3 aufnehmenden Bolzens 6 erfolgt nicht unmittelbar im Radträger 8, sondern unter Zwischenschaltung einer elastischen, beispielsweise aus Gummi bestehenden Hülse 11. Diese bewirkt eine elastische Lagerung des Bolzens 6 im Radträger 8. Gleichzeitig werden Reibungsgeräusche ausgeschaltet, die beim Vorhandensein von im Gewinde gleitenden Teilen auftreten.The bearing of the pin 6 receiving the trunnion 3 is not carried out directly in the wheel carrier 8, but with the interposition of an elastic sleeve 11, for example made of rubber. This causes an elastic mounting of the bolt 6 in the wheel carrier 8. At the same time, there are frictional noises eliminated, which occur in the presence of parts sliding in the thread.

Um eine gleichmäßige Belastung der Gummihülse 11 zu erreichen, ist diese mit einer weiteren metallenen Hülse 12 umgeben. Hierbei kann die Gummihülse 11 in die letztere einvuilkanisiert sein. Dadurch wird der Zusammenbau der Radaufhängung wesentlich erleichtert und beschleunigt.In order to achieve an even load on the rubber sleeve 11, it is provided with a further metal one Surrounding sleeve 12. Here, the rubber sleeve 11 can be vulcanized into the latter. This will the assembly of the wheel suspension is made much easier and faster.

Zur Schmierung des durch den Bolzen 6 und den Tragzapfen, 3 gebildeten Gewindegelenkes ist der Bolzen 6 mit einer Gewindeboh.rung 13 (Fig. 2) versehen, welche zur Befestigung eines Schmiernippels 14 dient.The bolt is used to lubricate the threaded joint formed by the bolt 6 and the trunnion, 3 6 is provided with a threaded hole 13 (FIG. 2) which is used to attach a lubricating nipple 14.
