Description

Abfederung, insbesondere für Kraftfahrzeuge Es ist bekannt, für die Abfederung von Wagen, insonderheit Kraftfahrzeugen, neben anderen Federn= sowohl gerade oder gewundene Drehungsfedern von beliebigem Querschnitt als auch rohrförmige Drehstabfedern zu verwenden, deren Wandung durchgehend axial geschlitzt ist.Cushioning, especially for motor vehicles It is known for the Suspension of cars, especially motor vehicles, among other springs = both straight or coiled torsion springs of any cross-section as well as tubular Use torsion bar springs whose wall is axially slotted throughout.

Von diesen bekannten Abfederungen unterscheidet sich der Gegenstand der Erfindung dadurch, daß die Schlitzränder der Drehstabfeder sich dauernd aufeinander abstützen, wodurch eine gleichmäßig weiche und stoßfreie Federung erreicht werden soll.The object differs from these known cushionings of the invention in that the slot edges of the torsion bar spring continuously on one another support, whereby an evenly soft and shock-free suspension can be achieved target.

In der Zeichnung ist der Gegenstand der Erfindung in mehreren Ausführungsformen beispielsweise dargestellt, und zwar zeigen Abb. i und 2 je ein Schaubild einer rohrförmigen Drehstabfeder in unbeanspruchtem und beanspruchtem Zustande und Abb. 3 bis 5 schematisch verschiedene Verbindungen der die Räder tragenden Schwinghebel mit dem Rahmen des Fahrzeuges unter Verwendung der Drehstabfeder nach der Erfindung.In the drawing, the subject of the invention is in several embodiments shown for example, namely Fig. i and 2 each show a diagram of a tubular torsion bar spring in unstressed and stressed condition and Fig. 3 to 5 schematically different connections of the rocker arms carrying the wheels with the frame of the vehicle using the torsion bar according to the invention.

Wie aus Abb. i ersichtlich, ist die rohrförmig,e Drehstabfeder i durchgehend axial geschlitzt und mit als Einspannmittel dienenden Zapfen 2 und 3 versehen, von denen der eine, 2, an einem Ende der Feder i diesseits und der andere, 3, am anderen Ende jenseits des Schlitzes befestigt ist.As can be seen from Fig. I, the tubular, e torsion bar spring i is continuous axially slotted and provided with pins 2 and 3 serving as clamping means, of which one, 2, at one end of the pen i on this side and the other, 3, at the other End beyond the slot is attached.

Da sich nun die Ränder der Schlitze erfindungsgemäß dauernd aufeinander abstützen, so verlagern sich bei einer Beanspruchung der Feder in Richtung der Pfeile (Abb.2) sowohl die Schlitzränder als auch die Endflächen der Drehstabfeder in Form einer Schraubenlinie, und zwar die ersteren in einer Schraubenlinie verhältnismäßig großer und die letzteren in einer Schraubenlinie verhältnismäßig kleiner Steigung.Since the edges of the slots are now permanently on top of each other according to the invention support, so shift when the spring is stressed in the direction of the arrows (Fig.2) both the edges of the slot and the end faces of the torsion bar spring in shape a helix, and the former in a helix proportionately large and the latter in a helical relatively small pitch.

Hierdurch wird neben einer geringen Änderung im Durchmesser der Feder eine Lageveränderung der Einspannstelllen 2, 3 bedingt, da sich die von den jeweiligen Schlitz- und Endflächen des Federkörpers gebildeten Ecken ¢ und 5 zueinander verlagern.This results in a small change in the diameter of the spring a change in position of the Einspannstelllen 2, 3 caused, since the respective Shift the corners ¢ and 5 formed by the slot and end faces of the spring body to one another.

plan erhält so eine Drehstabfeder, die weicher und stoßfreier arbeitet als die bekannten Drehstabfedern.plan receives a torsion bar spring that works softer and more shock-free than the well-known torsion bar springs.

In Abb.3 ist der Einbau einer Drehstabfeder gemäß der Erfindung gezeigt, und zwar greift dass seine Ende der Federn 8 und 9 je über einen der zylindrischen Fortsätze 12 eines starr mit dem Fahrzeug 7 verbundenen Stützlagers 6.In Fig.3 the installation of a torsion bar according to the invention is shown, and that engages its end of the springs 8 and 9 each over one of the cylindrical Extensions 12 of a support bearing 6 rigidly connected to the vehicle 7.

Durch .ein geeignetes Befestigungsmittel 13, z. B. Niet, sind die Federn mit dem Fortsatz 12 verbunden. Der Niet 13 durchgreift jedoch die Wandung der Federn nur einmal diesseits des Schlitzes, wogegen das den Schwinghebel i o, i i für das Rad mit den Federn verbindende Befestigungsmittel i q. die Federwandung nur jenseits des Schlitzes durchdringt, so daß die freien Endflächen der Federn in ihrem Spiel nicht behindert sind.By .a suitable fastening means 13, e.g. B. Rivet, they are Springs connected to the extension 12. However, the rivet 13 extends through the wall the springs only once on this side of the slot, whereas the rocker arm i o, i i for fastening means i q connecting the wheel to the springs. the spring wall penetrates only beyond the slot, so that the free end faces of the springs are not hindered in their game.

An Stelle der stabförmigen, in die Federn greifenden Fortsätze 12 können auch hohle verwendet werden, in die die Enden der Federn hineingreifen. Ebenso könnten die Fortsätze 12 flach ausgebildet sein und die Federn an diesen mit ihrer Außenfläche befestigt werden.Instead of the rod-shaped extensions 12 that grip into the springs can also be used hollow into which the ends of the feathers reach into it. The extensions 12 could also be flat and the springs be attached to these with their outer surface.

Gegebenenfalls kann man auch nahe dem4 Schwinghebel 10, i 1, wie in Abb. q. dax-'x gestellt, ein Stützlager 15 vorsehen, das mit dem Stützlager 6 bzw. 21 starr verbunden ist.If necessary, one can also close to the rocker arm 10, i 1, as in Fig.q. dax-'x, provide a support bearing 15 that is connected to the support bearing 6 or 21 is rigidly connected.

Die in Abb..l rechtsseitig dargestellte Einbauart der Federn unterscheidet sich im übrigen von der eben beschriebenen dadurch, daß das den Fortsatz 16 des Stützlagers 21 übergreifende Ende der Feder durch einen die Wandung der letzteren zweimal durchgreifenden Niet i8 befestigt ist. An dieser Stelle ist also die Federwirkung unterbunden, wobei die Endfläche der Federn an der starren Seitenfläche des Stützlagers 21 unmittelbar anliegt. Das andere Ende der Feder ist dagegen, wie in Abb.3 dargestellt, nur in einem Punkte 2o mit dem Schwinghebel verbunden. An dieser Stelle ist also das Spiel der Feder nicht behindert.The type of installation of the springs shown on the right in Fig. 1 differs differs from the one just described in that the extension 16 of the Support bearing 21 overlapping end of the spring through a wall of the latter double rivet i8 is attached. So at this point is the spring action prevented, the end face of the springs on the rigid side surface of the support bearing 21 is applied immediately. The other end of the spring, on the other hand, is, as shown in Figure 3, connected to the rocker arm only at one point 2o. So at this point is does not hinder the play of the spring.

Zwischen der Endfläche der Feder und dem starren Stützlager 21 kann man eine einstellbare Fläche, z. B. eine gesicherte Mutter, vorsehen, um das Spiel der Federn und somit deren Nachgiebigkeit beliebig regeln zu können. Ebenso kann man, wie in Abb.:1 linksseitig gezeigt, zwischen der Endfläche der Drehstabfeder und dem starren Stützlager 21 Federn, z. B. Tellerfedern 22, einsetzen, die entweder unmittelbar an dem starren Stützlager 2i oder wiederum gegen eine einstellbare Fläche anliegen. Gemäß Abb.5 ist für zwei Räder eine rohrförmige Drehstabfeder 26 verwendet, an der die Hebel 2.4 mit den Achszapfen 23 durch ein Verbindungsmittel 25 in einem .unkte befestigt sind. In der Mitte der t@Wirfeder ist ein Stützlager 27 vorgesehen, [email protected] durch einen Bolzen 28 derart gespannt werden kann, daß sowohl die Stellung der Hebel 24 beliebig gewählt als auch die Federung geregelt werden kann.Between the end face of the spring and the rigid support bearing 21 can an adjustable area, e.g. B. a secured mother, provide to the game of the springs and thus their flexibility as required. Likewise can as shown in Fig. 1 on the left, between the end face of the torsion bar and the rigid support bearing 21 springs, for. B. disc springs 22, use either directly on the rigid support bearing 2i or again against an adjustable surface issue. According to Figure 5, a tubular torsion bar spring 26 is used for two wheels, on which the lever 2.4 with the journal 23 by a connecting means 25 in one .points are attached. A support bearing 27 is provided in the middle of the t @ vortex spring, c @ .s can be tensioned by a bolt 28 in such a way that both the position the lever 24 can be selected as desired and the suspension can be regulated.
