Abstract

The independently sprung wheel is mounted at the bottom end of a telescopic damper (5) and is further braced on the chassis by a lateral support brace (4). In order to dampen road vibrations, and prevent their being transmitted to the car body via the damper, the damper (5) is mounted with upper (7) and lower (6) elastic pads. The pads are mounted at the ends of a metal tubular housing (8) which is rigidly attached with its sealed bottom end on the wheel support (3). The elastic pads serve to isolate the damper from high frequency vibrations and also reduce wear in the damper.

Description

Geradführung für unabhängig aufgehängte Räder von Kraftfahrzeugen Die Erfindung bezieht sich auf eine Geradführung für unabhängig aufgehängte Räder von Kraftfahrzeugen, bei der der Achsschenkelträger unten von einem Querlenker und oben von einem Teleskopdämpfer geführt wird.Straight guidance for independently suspended wheels of motor vehicles The invention relates to a straight line guide for independently suspended wheels of motor vehicles, in which the steering knuckle support is below a wishbone and is guided above by a telescopic damper.

Üblicherweise sind die Stoßdämpfer starr mit dem Achsschenkelträger verbunden. Sie übertragen infolgedessen Schwingungen und Geräusche, die beim Abrollen der Laufräder auf der Straße oder durch Bewegungen des Antriebsaggregates entstehen, auf eine Stelle im Radhaus bzw. an der Karosserie, die meist ihrer Ausbildung nach diese Schwingungen als Dröhngeräusche in das Wageninnere übertragen kann.Usually the shock absorbers are rigid with the steering knuckle carrier tied together. As a result, they transmit vibrations and noises when rolling the wheels are created on the road or by movements of the drive unit, to a point in the wheel arch or on the body, usually according to their training these vibrations can be transmitted as booming noises into the interior of the car.

Aufgabe der Erfindung ist es, die störende Wirkung von solchen Schwingungen zu verringern.The object of the invention is to reduce the disruptive effect of such vibrations to reduce.

Die erfindungsgemäße Lösung besteht darin, daß der Stoßdämpfer über zwei federnd nachgiebige Lager z.B. Gummiringe in einem mit dem Achsschenkelträger fest verbundenen Gehäuse gelagert ist.The solution according to the invention is that the shock absorber over two resilient bearings e.g. rubber rings in one with the steering knuckle carrier permanently connected housing is mounted.

Die beim Abrollen auf der Straße und durch Bewegungen des Antriebsaggregates erzeugten Schwingungen im Achsschenkelträger werden durch die beiden federnd nachgiebigen Lager gedämpft bzw. absorbiert und so nicht oder nur gedämpft auf die Befestigung der Geradführung an der Karosserie weitergeleitet. Diese Geradführung hat auch den Vorteil, daß sie in eine Masse des Achsschenkelträgers und eine davon unabhängige Masse des Stoßdämpfers aufgeteilt ist.When rolling on the road and by movements of the drive unit Vibrations generated in the steering knuckle are resilient due to the two Bearing damped or absorbed and so not or only damped on the attachment the straight line on the body. This straight line also has the The advantage of being in a mass of the steering knuckle and an independent one therefrom Mass of the shock absorber is divided.

Das Gehäuse kann aus einem unten durch einen Boden geschlossenen Rohr bestehen und das obere federnd nachgiebige Lager kann mit einer Kappe am Gehäuse abgestützt sein.The housing can consist of a tube closed at the bottom by a base exist and the upper resilient bearing can with a cap on the housing be supported.

Die Zeichnung zeigt in schematischer Darstellung ein Ausführungsbeispiel.The drawing shows a schematic representation of an embodiment.

Das Rad 1 ist mit der Geradführung 2 am Kraftfahrzeug unabhängig aufgehängt. Der Achsschenkelträger 3 wird unten von einem Querlenker 4 und oben von einem Teleskopstoßdämpfer 5 geführt. Der Stoßdämpfer 5 ist über zwei federnd nachgiebige Lager 6, 7 in einem Gehäuse 8 gelagert. Dieses ist mit dem Achsschenkelträger 3 bei 9 fest verbunden. Das Gehäuse 8 besteht aus einem Rohr 10, das unten durch einen Boden 11 geschlossen ist. Das obere federnd nachgiebige Lager 7 ist mit einerKappe 12 am Gehäuse 8 abgestützt.The wheel 1 is independently suspended with the straight line guide 2 on the motor vehicle. The steering knuckle support 3 is supported by a wishbone 4 at the bottom and a telescopic shock absorber at the top 5 led. The shock absorber 5 is in one via two resilient bearings 6, 7 Housing 8 stored. This is firmly connected to the steering knuckle carrier 3 at 9. The housing 8 consists of a tube 10 which is closed at the bottom by a base 11 is. The upper resilient bearing 7 is supported on the housing 8 with a cap 12.
