Description

Die Erfindung bezieht sich auf eine Drehstabfederung für Fahrzeuge, insbesondere für Kraftfahrzeuge, deren Federstäbe unmittelbar zu einem Rad- oder Achsführungs- oder Federungslenker abgebogen sind.The invention relates to a torsion bar suspension for vehicles, in particular for motor vehicles, their spring bars bent directly to a wheel or axle guide or suspension control arm are.

Die Erfindung besteht darin, daß zwei übereinander angeordnete Lenkerpaare für jede Fahrzeugseite vorgesehen sind, von denen der eine Lenker unmittelbar die Räder und der andere die AchseThe invention consists in that two pairs of handlebars arranged one above the other for each side of the vehicle are provided, of which one link directly the wheels and the other the axle

ίο abfedert.ίο cushions.

Durch die Verwendung der Federstäbe unmittelbar als Radführungs- und Achslenker kommt man ohne besondere Radführungsglieder aus. Außerdem kann die Länge der Federstäbe besonders gut ausgenutzt werden. Weiterhin wird eine hochelastische Abfederung erzielt, ohne daß die Federkinematik selbst beeinträchtigt wird. Der Aufbau der Rad- und Achsführung sowie die Abfederung werden außerordentlich einfach und übersichtlich. Die An-Ordnung benötigt wenig Platz und bedarf keiner besonderen Wartung.By using the spring bars directly as a wheel guide and axle guide, you get without special wheel guide links. In addition, the length of the spring bars can be used particularly well will. Furthermore, a highly elastic cushioning is achieved without the spring kinematics itself is affected. The structure of the wheel and axle guide as well as the suspension will be extremely simple and clear. The arrangement requires little space and does not require any special maintenance.

Es sind zwar schon Kraftfahrzeuge mit unmittelbar zu Rad- oder Achsführungslenkern abgebogenen Drehstabfedern bekannt, bei denen aber für jede Fahrzeugseite jeweils nur ein Lenker verwendet wird. Außerdem besteht das Federungselement bei den bekannten Anordnungen nicht aus einem einheitlichen Drehfederstab, sondern aus einem Drehstab und einer Flachbandfeder. Von den bereits erwähnten Vorteilen abgesehen ist beim Erfindungsgegenstand die Rad- und Achsfederung durch die vertikale Aufteilung der Federungsglieder zuverlässiger als bei der bekannten Anordnung.It is true that there are already motor vehicles with directly bent to wheel or axle guide links Torsion bar springs are known, but in which only one handlebar is used for each side of the vehicle will. In addition, the suspension element does not consist of one in the known arrangements unitary torsion spring bar, but instead of a torsion bar and a flat ribbon spring. Of those already The mentioned advantages apart from the subject matter of the invention is the wheel and axle suspension through the vertical division of the suspension members more reliable than in the known arrangement.

In der Zeichnung ist die Erfindung in einem Schaubild der Hinterachse eines Kraftfahrzeuges dargestellt.In the drawing, the invention is in a diagram of the rear axle of a motor vehicle shown.

Die Fahrzeugräder ι werden entweder von einer starren oder schwingenden Starrachse 2 oder durch Pendelachsen geführt. Die Achse sitzt am Ende eines Schubrohres 3, an welchem bei angetriebenen Rädern 1 gleichzeitig das Ausgleichsgetriebe 4 angeordnet ist.The vehicle wheels ι are either by a rigid or oscillating rigid axle 2 or by Pendulum axles guided. The axis sits at the end of a thrust tube 3, on which when driven Wheels 1 at the same time the differential gear 4 is arranged.

Für jedes Rad 1 ist ein Drehfederlenker 5,5 vorgesehen. Beide Lenker gehen in einen Bügel 5 α über, der sich in Fahrzeuglängsrichtung nach hinten oder vorn erstreckt. In der Zeichnung ist ein nach vorn weisender Bügel ζ α dargestellt. Die Lenkerenden greifen an den üblichen festliegenden Radteilen, z.B. am Bremstrommelgehäuse 6, der Fahrzeugräder an.A torsion spring link 5.5 is provided for each wheel 1. Both links go into a bracket 5 α , which extends in the longitudinal direction of the vehicle to the rear or to the front. In the drawing, a forward-facing bracket ζ α is shown. The handlebar ends engage the usual fixed wheel parts, for example the brake drum housing 6, of the vehicle wheels.

Am Übergang der Lenker 5 in dem mittleren Bügelabschnitt 5 α sind elastische Drehlager 7, 7 vorgesehen. Je ein weiteres Elastiklager 8, 8 befindet sich an den äußeren Umbiegungen des Federstabes 5. Außerdem ist der Bügel S α noch einmal an seinem Steg am Fahrzeugrahmen oder an einem diesen ersetzenden Wagenkastenboden festgehalten (9).Elastic pivot bearings 7, 7 are provided at the transition between the links 5 in the middle bracket section 5 α. Another elastic bearing 8, 8 is located on the outer bends of the spring bar 5. In addition, the bracket S α is once again held on its web on the vehicle frame or on a car body floor that replaces it (9).

Durch einen ähnlich gestalteten Federbügel ist auch die Achse 2 abgefedert. Es besteht dieser wiederum aus dem eigentlichen Bügelabschnitt 10, dessen nach außen quer abgebogene Schenkel 10 a, 10 a an wiederum nach unten abgewickelten Enden j 10& festgelegt sind. Die Befestigung erfolgt durch elastische Lager 11 und 12 an den Abbiegungen α des Bügels 10. Ein weiteres Elastiklager 13 befindet sich am Steg des Bügels 10, der vom Achsgetriebegehäuse 4 nach oben ragt. Im Rahmen der Erfindung kann der Bügel 10 auch nach vorn und der Bügel 9 nach rückwärts weisen sowie die untere Feder der Achsführung und die obere der Radführung dienen. Die vorgesehenen Lager 7, 8, 9, 12 und sind reine Drehlager, insbesondere Metallgummilager und/oder selbstschmierende Kunststofflager. Für die Aufnahme der axialen Schubkräfte dient ein geeigneter Anschlag, z. B. ein Bundring, eine Muffe oder eine Stellschraube.Axis 2 is also cushioned by a similarly designed spring clip. This in turn consists of the actual bracket section 10, the outwardly transversely bent legs 10 a, 10 a of which are fixed at ends j 10 & that are again unwound downwards. The fastening is carried out by elastic bearings 11 and 12 on the bends α of the bracket 10. Another elastic bearing 13 is located on the web of the bracket 10, which protrudes from the axle gear housing 4 upwards. In the context of the invention, the bracket 10 can also point to the front and the bracket 9 to the rear, and the lower spring can be used for the axle guide and the upper spring for the wheel guide. The intended bearings 7, 8, 9, 12 and are pure pivot bearings, in particular metal-rubber bearings and / or self-lubricating plastic bearings. A suitable stop, e.g. B. a collar, a sleeve or a set screw.
