Description

Federnde Einzelradaufhängung für Kraftfahrzeuge od. dgl. 1?inzelradal>federurrgen sind im Fahrzeugbau bekannt. Bei vierrädrigen Straßenfahrzeugen geht man wegen der durch Unebenheiten der Fahrbahn verursachten Einzelbewegungen der Räder auf die voneinander unabhängige Federung der einzelnen ltä<ier aus. Im Kraftfahrzeugi>au werden z. B. die einzeln abgefederten Räder an durch Lenker oder ähnliche Bauteile schwingend geführte Achsschenkel gelagert.Spring independent wheel suspension for motor vehicles or the like 1? Single wheel> federurrgen are known in vehicle construction. With four-wheeled road vehicles you go because of the Individual movements of the wheels caused by unevenness in the roadway on the independent suspension of the individual countries. In the motor vehicle are z. B. the individually sprung wheels on by handlebars or similar components swinging guided steering knuckles mounted.

1:s ist auch schon vorgeschlagen worden, den Achsschenkel, auf dem das abzufedernde Rad angeordnet ist, mit einer lotrecht geführten Kolbenstange zu versehen, welche mittels eines Kolbens in einem am Fahrgestell angebrachten Zylinder ,durch Preßluft elastisch abgestützt ist. Die Wirkung dieser Luftfederung muß durch Nachfüllen der Preßluft geregelt und aufrechterhalten werden. Es ist dazu eine die Verwendung dieser Federung verteuernde Drucklufterzeugungsanlage notwendig. Aus diesem Grunde ist die praktische Verwendung dieser Ausbildungform sehr beschränkt.1: s has also been suggested, the steering knuckle on which the wheel to be cushioned is arranged with a vertically guided piston rod provided, which by means of a piston in a cylinder attached to the chassis , is elastically supported by compressed air. The effect of this air suspension must be through Refilling the compressed air can be regulated and maintained. It is also a die Use of this suspension, which increases the price of a compressed air generation system, is necessary. the end for this reason, the practical use of this form of training is very limited.

Bei Omni.l>usfa:hrzeugen hat man bereits vorgeschlagen, unter Verwendung einer Radabstützung ,durch ein in einem Lagergestell geführtes Radlager die Räder abzufedern. Die Lenkung des Fahrzeuges durch Schwenken der Räder in ihrer Mittelebene soll hierbei durch zwischen den alsZwillingsrädern ausgebildeten Rädern des Fahrzeuges angeordnete senkrechte Führungs- und Stützstangen er- der Schnecke entsprechende Führungsrippen aufweist. Gegen die Stirnfläche dieser Schnecke 24 stützen sich -die Schraubenfedern 26 und 27 !b. Sie legen sich andererseits gegen Bunde 28, sind gleich stark und zentrieren daher die Schnecke immer auf Mittelstellung.In Omni.l> usfa: hrzeugen it has already been proposed to use a wheel support to cushion the wheels through a wheel bearing guided in a bearing frame. The steering of the vehicle by swiveling the wheels in their center plane should be achieved by vertical guide and support rods arranged between the twin wheels of the vehicle. has guide ribs corresponding to the screw. The helical springs 26 and 27 are supported against the end face of this worm 24. On the other hand, they lie against collar 28, are equally strong and therefore always center the worm in the middle position.

Claims

PATENT CLAIMS: t. Spring-loaded independent wheel suspension for motor vehicles or the like, characterized in that the steering knuckle (2) of the wheel, which is provided with guides (7, To) acting parallel to the wheel plane, with the interposition of helical springs (12, 18), is fastened to the chassis frame and overlaps the wheel center Yoke (13) is supported.

2. Independent wheel suspension according to claim i, characterized in that that the guide consists of two parallel guide tubes attached to the yoke (13) (To) and a bridge (5) which carries the axis of the tenicle and which with Slide rods (7) is slidably mounted in the tubes (io).

3. Independent suspension according to claims i and 2, characterized in that the guide tube (io) is one Carry spring plate (i i) between (learn and the bottom of one of the bridge (5) formed Spring sleeve (6) a helical spring (12) is clamped.

Independent suspension according to Claims 1 to 3, characterized in that the bridge (5) with the slide rod (7) coaxial guide sleeves (8) is provided, which by means of a sliding bush (9) encompass the guide tubes (io).

5. Independent wheel suspension according to claim i, thereby characterized in that a pipe socket (i9) is arranged in the middle of the bridge (5) is, which serves as a holder of a support spring (18) and whose end face is on At the end of the suspension stroke, it is supported against a rubber buffer (2o) fastened to the yoke (13).

6. Independent wheel suspension according to claim i, characterized in that the yoke (13) by means of a pivot pin (15) arranged coaxially to the vertical wheel center is connected to the mounting plate (.14) provided with a thrust bearing.

7. Independent wheel suspension for motor vehicles. The like. According to claim 1, 2 and 6, for Steerable front wheels, characterized in that on each axis of rotation (16) of the front wheels a sprocket (17) sits, over which a joint chain runs, which in a third chain wheel (21) engages, which sits on a worm wheel (23) whose on the steering column (25) displaceable worm (24) by two against this worm supporting coil springs (26, 27) is held in the middle position. B. Independent suspension , for motor vehicles or the like according to claim 1, 2, 6 and 7, characterized in that that the worm drive is set as a separate unit between the crossbars is.
