Abstract

A shock absorber spring unit (6) fitted externally to the wheel is joined to the vehicle chassis (10) by wishbones (1,2), a track rod (11) and a tie bar (7). Additional components include the disk brake (16) and wheel unit (17) and the support tube (13) containing the wheel bearings and two part wheel hub and the absorber is secured at one end to the tube (13) and has an inside thread for the nut (18) used to locate and pre-tension the springs (19). Ring (22) guards against absorber slippage and skewing.

Description

Es ist bekannt, bei Radaufhängungen für Straßenfahrzeuge aller Art die zur Abfederung und Dämpfung des Fahrzeugaufbaus verwendete Kombination aus Feder und Schwingungsdämpfer am Fahrzeugaufbau direkt anzubringen. Die Dämpfer-/Federeinheit übernimmt hierbei niemals eine radtragende Funktion. Dadurch wird zur Rad- und Bremsaufnahme ein Radträger benötigt. Zudem sind alle radführenden Elemente beweglich zum Aufbau angebracht, um eine Relativ­ bewegung des Rades zum Fahrzeugaufbau zu ermöglichen.It is known that the suspension and suspension for road vehicles of all types Damping of the vehicle body uses a combination of spring and vibration damper to be attached directly to the vehicle body. The damper / spring unit never takes over a wheel-bearing function. This means that a wheel carrier is required to hold the wheel and brake. In addition, all wheel-guiding elements are movably attached to the body in order to be relative to allow movement of the wheel to the vehicle body.

Der im Patentanspruch angegebenen Erfindung liegt das Problem zugrunde, die Summe der un­ gefederten Massen und die Anzahl der beweglichen Teile einer Radaufhängung unter Berück­ sichtigung von entstehenden Toleranzen und Reibung zu verringern. Bei Fahrzeugen mit offenen Rädern (im Formel-Rennsport) ergeben sich zusätzlich aerodynamische Vorteile durch die Ver­ kleidung der unbeweglichen, zum vollständig abgefederten Teil des Fahrzeuges gehörenden (laut Reglement) Querlenker mit Flügelprofilen zur Erzeugung von negativem Auftrieb zur Ver­ besserung der Straßenhaftung.The invention specified in the claim is based on the problem, the sum of the un sprung masses and the number of moving parts of a wheel suspension under consideration to reduce tolerance and friction. For vehicles with open Wheels (in formula racing) also have aerodynamic advantages due to the Ver clothing of the immovable part of the vehicle that is fully sprung (no Regulations) wishbones with wing profiles to generate negative lift for ver improvement in road grip.

Dieses Problem wird durch die im Patentanspruch aufgeführten Merkmale gelöst.This problem is solved by the features listed in the claim.

Die erreichten Vorteile bestehen darin, durch die Reduzierung der ungefederten Massen eine bessere Straßenhaftung und durch die Reduzierung der Toleranzen und der Reibung eine exaktere Radführung zu ermöglichen. Zudem ergeben sich die o.g. aerodynamischen Vorteile für Rennfahrzeuge.The advantages achieved are one by reducing the unsprung masses better road grip and by reducing tolerances and friction to enable more precise wheel guidance. In addition, the above aerodynamic advantages for Racing cars.

Ein Ausführungsbeispiel zeigen die Fig. 1 und Fig. 2 in der Anlage. Die Stehlin-Reinhold- Radaufhängung 1 besteht aus einem oberen (1) und einem unteren (2) Dreieckslenker, die beide mittels Uniballgelenken (3) und (4) am Fahrzeugaufbau (10) befestigt sind. Beide Dreieckslenker sind demzufolge nicht starr angebracht, sondern vertikal um ihre Anlenkpunkte beweglich. Am oberen Dreieckslenker sind die Uniballgelenke fest, am unteren mit Gewindestange zur Längen­ verstellung versehen. Dies dient der Einstellung des Radnachlaufes.An embodiment shown in FIGS. 1 and Fig. 2 in the plant. The Stehlin-Reinhold wheel suspension 1 consists of an upper ( 1 ) and a lower ( 2 ) wishbone, both of which are attached to the vehicle body ( 10 ) by means of universal ball joints ( 3 ) and ( 4 ). Both wishbones are therefore not rigidly attached, but can be moved vertically around their articulation points. The uniball joints are fixed on the upper wishbone, and a threaded rod for length adjustment on the lower. This is used to set the wheel tracking.

Am äußeren Ende des oberen Dreieckslenkers befindet sich ein eingelassenes Uniballgelenk (5) zur Aufnahme des Dämpfers (6). Neben diesem Aufnahmepunkt befindet sich ein Anlenkpunkt für die Zugstrebe (7), an deren Enden sich je ein Uniballgelenk (8) mit Gewindestange zur Längenänderung befinden. Das untere Ende der Zugstrebe ist mit dem Fahrzeugaufbau ver­ bunden.At the outer end of the upper wishbone there is a recessed uniball joint ( 5 ) for receiving the damper ( 6 ). In addition to this mounting point there is a pivot point for the tension strut ( 7 ), at the ends of which there is a uniball joint ( 8 ) with a threaded rod for changing the length. The lower end of the tension strut is connected to the vehicle body.

Die Lenkung besteht aus einer Zahnstangenlenkung (9), die sich am unteren Ende der Front des Fahrzeugaufbaus (10) befindet. Über eine Spurstange (11) versehen mit Uniballgelenken mit Ge­ windestangen zur Längenänderung (12) werden Bewegungen der Lenkung an das Tragrohr (13) des Dämpfers, das als Radträger fungiert, übertragen.The steering consists of a rack and pinion steering ( 9 ), which is located at the lower end of the front of the vehicle body ( 10 ). Via a tie rod ( 11 ) provided with Uniball joints with Ge threaded rods for length change ( 12 ) movements of the steering to the support tube ( 13 ) of the damper, which acts as a wheel carrier, are transmitted.

Das Tragrohr (13) wird mit einem Stehbolzen (14) in ein Uniballgelenk (15) im unteren Dreieckslenker (2) geführt und verschraubt.The support tube ( 13 ) is guided with a stud bolt ( 14 ) into a uniball joint ( 15 ) in the lower wishbone ( 2 ) and screwed.

Im Inneren des Tragrohres (13) befinden sich zwei Radlager (20) und eine zweiteilige Radnabe (21), die nach heutigem Standard ausgeführt sind. Die Radnabe nimmt an ihrem äußeren Ende die Bremsscheibe (16) und die Radmutter (17) auf, außerdem dient sie der Zentrierung und Aufnahme des Rades.Inside the support tube ( 13 ) there are two wheel bearings ( 20 ) and a two-part wheel hub ( 21 ), which are designed according to today's standard. The wheel hub receives the brake disc ( 16 ) and the wheel nut ( 17 ) at its outer end, and it also serves for centering and receiving the wheel.

Der Dämpfer (6) ist mit seinem unteren Ende im Tragrohr (13) befestigt, und zudem ist ein Außengewinde am Dämpferzylinder angebracht, das eine Nutmutter (18) aufnimmt, die der Fixierung und Vorspannung der Feder (19) dient. Ein mit dem Tragrohr verschraubter Ring (22) fixiert den Dämpfer gegen ein Herausrutschen bei Ausfederbewegungen.The damper ( 6 ) is fastened with its lower end in the support tube ( 13 ), and an external thread is also attached to the damper cylinder, which receives a lock nut ( 18 ), which is used to fix and bias the spring ( 19 ). A ring ( 22 ) screwed to the support tube fixes the damper against slipping out during rebound movements.

Die beschriebene Radaufhängung ist als Vorder- und Hinterachse gleichermaßen verwendbar, bei einer Antriebsachse kommt lediglich eine Verbindung der Radnabe (21) mit einer Antriebs­ welle und bei einer ungelenkten Radaufhängung eine Fixierung der Spurstangen hinzu.The wheel suspension described can be used equally as a front and rear axle, with a drive axle only a connection of the wheel hub ( 21 ) with a drive shaft and with a non-steered wheel suspension a fixation of the tie rods.

Die Verbindung zwischen Dämpfer-/Federeinheit und Fahrzeugaufbau wurde im obigen Beispiel mit Dreieckslenkern ausgeführt, es ist jedoch jede andere Verbindung (z. B. ein starrer, biege­ steifer Querlenker) denkbar.The connection between damper / spring unit and vehicle body was in the example above Executed with wishbones, but it is any other connection (e.g. a rigid, bend rigid wishbone) conceivable.

Das obige Beispiel entspricht in seiner Ausführung speziell dem Reglement der FIA (Féderation International d'Automobile) für Formelfahrzeuge im Automobilrennsport. The execution of the example above corresponds specifically to the regulations of the FIA (Federation International d'Automobile) for formula vehicles in automobile racing.
