Die Erfindung betrifft ein höhenverstellbares Federbein für Kraftfahrzeuge nach dem Oberbegriff des Anspruchs 1.The invention relates to a height-adjustable spring strut for motor vehicles according to the preamble of claim 1.
Bekannte höhenverstellbare Federbeine weisen insbesondere eine Auflage in Form eines weiteren Federtellers auf, welcher mit einem Innengewinde versehen und auf dem Schutzrohr - entlang einer Außengewindestrecke verstellbar ist. Dabei ist ein Konterring unterhalb des Federtellers vorgesehen, welcher einerseits der Unterstützung des Federtellers und andererseits dessen Arretierung dient.Known height-adjustable spring struts in particular have a support in the form of another spring plate, which is provided with an internal thread and is adjustable on the protective tube along an external thread section. A lock ring is provided below the spring plate, which serves on the one hand to support the spring plate and on the other hand to lock it in place.
Für solche gattungsgemäßen Federbeine gelten verschiedene Nachteile: Zunächst ist deren Herstellung sehr aufwendig. Ferner sind sie anfällig gegen Verschmutzung. Darüber hinaus besteht aufgrund ihrer stufenlosen Verstellbarkeit die Gefahr ungleicher Höheneinstellungen.There are various disadvantages to such generic suspension struts: First of all, they are very complex to manufacture. Furthermore, they are susceptible to dirt. In addition, due to their infinitely adjustable nature, there is a risk of uneven height settings.
Andere bekannte höhenverstellbare Federbeine weisen eine Auflage in Form eines weiteren Federtellers auf, welcher mit einem Sprengring zusammenwirkt, wobei der Sprengring in eine von mehreren Ringnuten am Schutzrohr einsetzbar ist.Other known height-adjustable spring struts have a support in the form of another spring plate, which interacts with a snap ring, whereby the snap ring can be inserted into one of several ring grooves on the protective tube.
Nachteilig ist bei solchen gattungsgemäßen Federbeinen wiederum deren aufwendige Herstellung. Zudem sind sie unbequem in der Montage.The disadvantage of such generic spring struts is that they are complex to manufacture. They are also inconvenient to install.
Die Aufgabe der Erfindung besteht darin, ein Federbein der eingangs genannten Art derart weiterzubilden, daß es höheneinheitlich verstellbar, preiswert und leicht herstellbar, bequem montierbar sowie weitgehend schmutzunempfindlich ist.The object of the invention is to further develop a spring strut of the type mentioned at the beginning in such a way that it is adjustable in height, inexpensive and easy to manufacture, easy to install and largely insensitive to dirt.
Die Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst.The object is achieved according to the invention by the characterizing features of claim 1.
Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, daß eine einheitliche Höhenverstellbarkeit erzielbar ist. Zudem läßt sich das erfindungsgemäße Federbein leicht montieren und preiswert herstellen. Darüber hinaus ist es weniger anfällig gegen Verschmutzungen.The advantages achieved with the invention are in particular that a uniform height adjustability can be achieved. In addition, the spring strut according to the invention is easy to assemble and inexpensive to manufacture. In addition, it is less susceptible to dirt.

Zusätzliche Einzelheiten und weitere Vorteile werden nachfolgend an Hand bevorzugter Ausführungsbeispiele in Verbindung mit der beigefügten Zeichnung beschrieben. Darin zeigen:Additional details and further advantages are described below using preferred embodiments in conjunction with the attached drawings. In them:
Fig. 1 ein erfindungsgemäßes höhenverstellbares Federbein in Seitenansicht, Fig. 1 shows a height-adjustable spring strut according to the invention in side view,
Fig. 2 eine untere Auflage als Schweißkonstruktion in vergrößerter Darstellung
(teilweise geschnitten),
30Fig. 2 a lower support as a welded construction in an enlarged view (partially sectioned),
30
Fig. 3 eine untere Auflage als Drehteil in vergrößerter Darstellung (teilweise geschnitten).Fig. 3 shows a lower support as a turned part in an enlarged view (partially sectioned).
Das in Fig. 1 dargestellte höhenverstellbare Federbein besteht aus einem mit
einer Befestigungslasche 14 versehenen Schutzrohr 10 sowie einer darin angeordneten Kolben-Zylinder-Einheit (20, 21), welche mit einer Schraubenfeder
22 derart zusammenwirkt, daß die Schraubenfeder 22 zwischen einem am oberen Ende der Kolbenstange 20 angeordneten Federteller 30 und
einer wählbaren Auflage am Schutzrohr 10 eingespannt ist. Die Auflage besteht erfindungsgemäß allein in einem verbreiterten unteren Abschnitt 11
des Schutzrohres 10.
10The height-adjustable spring strut shown in Fig. 1 consists of a protective tube 10 provided with a fastening tab 14 and a piston-cylinder unit (20, 21) arranged therein, which interacts with a coil spring 22 in such a way that the coil spring 22 is clamped between a spring plate 30 arranged at the upper end of the piston rod 20 and a selectable support on the protective tube 10. According to the invention, the support consists solely in a widened lower section 11 of the protective tube 10.
10
Nach Fig. 2 ist dieser verbreiterte Abschnitt 11 mittels einer am Schutzrohr 10 aufgeschweißten Hülse 12 gebildet.According to Fig. 2, this widened section 11 is formed by means of a sleeve 12 welded onto the protective tube 10.
Alternativ können das Schutzrohr 10 und der verbreiterte Abschnitt 11 auch sozusagen „aus dem Vollen gedreht", d.h. als einheitliches Drehteil ausgebildet sein, so wie in Fig. 3 dargestellt.Alternatively, the protective tube 10 and the widened section 11 can also be "turned from solid", so to speak, i.e. formed as a single turned part, as shown in Fig. 3.
Wie im übrigen ersichtlich, ist zur Höhenverstellung ein auf das Schutzrohr 10 aufsteckbarer Satz von Distanzringen 13 mit einheitlicher Höhe vorgesehen. Die Distanzhöhen liegen vorzugsweise zwischen 5 und 10 mm. Der Außendurchmesser der Distanzringe entspricht demjenigen des verbreiterten unteren Abschnitts 11 des Schutzrohres 10.As can also be seen, a set of spacer rings 13 of uniform height that can be attached to the protective tube 10 is provided for height adjustment. The spacer heights are preferably between 5 and 10 mm. The outer diameter of the spacer rings corresponds to that of the widened lower section 11 of the protective tube 10.
Das Schutzrohr 10 samt seinem unteren Abschnitt 11 und die Distanzringe 13 bestehen hier aus rostfreiem Stahl.The protective tube 10 including its lower section 11 and the spacer rings 13 are made of stainless steel.
Zusammenfassend läßt sich folgendes sagen. Ein höhenverstellbares Federbein für Kraftfahrzeuge, bestehend aus einem Schutzrohr 10 sowie einer darin angeordneten Kolben-Zylinder-Einheit 20, 21, welche mit einer Schraubenfeder 22 zusammenwirkt, wobei die Schraubenfeder 22 zwischen einem am oberen Ende der Kolbenstange 20 angeordneten Federteller 30 und einer wählbaren Auflage am Schutzrohr 10 eingespannt ist, wirdIn summary, the following can be said. A height-adjustable spring strut for motor vehicles, consisting of a protective tube 10 and a piston-cylinder unit 20, 21 arranged therein, which interacts with a coil spring 22, wherein the coil spring 22 is clamped between a spring plate 30 arranged at the upper end of the piston rod 20 and a selectable support on the protective tube 10, is
dahingehend weitergebildet, daß sie höheneinheitlich verstellbar, preiswert und leicht herstellbar, bequem montierbar sowie weitgehend schmutzunempfindlich ist. Hierzu schlägt die Erfindung eine Auflage vor, welche allein in einem verbreiterten unteren Abschnitt 11 des Schutzrohres 10 besteht. Zur Höhenverstellung ist ein Satz auf das Schutzrohr 10 aufsteckbarer Distanzringe 13 einheitlicher Höhe mit einem Außendurchmesser von mindestens demjenigen des verbreiterten unteren Abschnitts 11 des Schutzrohres 10 vorgesehen.developed in such a way that it is adjustable to a uniform height, inexpensive and easy to manufacture, easy to assemble and largely insensitive to dirt. For this purpose, the invention proposes a support which consists solely of a widened lower section 11 of the protective tube 10. For height adjustment, a set of spacer rings 13 of uniform height that can be attached to the protective tube 10 and have an outer diameter of at least that of the widened lower section 11 of the protective tube 10 is provided.
