Abstract
Description
Die Erfindung betrifft eine Vorrichtung zum mechanischen Verstellen von wenigstens zwei in oder an einem Dämpfungskolben eines hydraulischen Stoßdämpfers angeordneten Stelleinrichtungen nach dem Oberbegriff des Anspruchs 1.The invention relates to a device for the mechanical adjustment of at least two in or on one damping piston a hydraulic shock absorber arranged Actuators according to the preamble of claim 1.
Hydraulische Stoßdämpfer werden zur Dämpfung der Bewegung von über Federn angelenkten Radaufhängungen vorzugsweise bei Kraftfahrzeugen eingesetzt. Dabei erfolgt die Dämpfung durch das Durchpressen von Dämpfungsflüssigkeit durch vorzugsweise federbelastete Durchtritte im Arbeitskolben von einem Arbeitsraum in den anderen Arbeitsraum des mit Dämpfungsflüssigkeit gefüllten Stoßdämpferrohres.Hydraulic shock absorbers are used to dampen the Movement from above Springs hinged wheel suspensions preferably used in motor vehicles. The damping takes place through the Pressing damping fluid through by preferably spring-loaded passages in the working piston of one working room in the other working room with damping fluid filled shock absorber tube.
Um eine definierte verringerte Dämpfung bei kleineren Kolbengeschwindigkeiten zu erzielen, ist es bekannt, hydraulisch parallel zu den Durchbrüchen im Arbeitskolben Bypassöffnungen vorzusehen, die die beiden Arbeitsräume hydraulisch miteinander verbinden. Es ist weiterhin bekannt, den Querschnitt der Durchtrittsöffnungen des Bypasses einstellbar zu gestalten, wobei die Einstellung des Bypasses über zwei Einstelleinrichtungen, jeweils getrennt für das Einfahren der Kolbenstange in den Stoßdämpfer bzw. für das Ausfahren der Kolbenstange aus dem Stoßdämpfer heraus, vorgesehen sein kann.A defined reduced damping for smaller ones To achieve piston speeds, it is known to be hydraulic parallel to the breakthroughs bypass openings in the working piston to provide the two working spaces hydraulically with each other connect. It is also known the cross section of the passage openings to make the bypass adjustable, the setting of the Bypasses over two adjustment devices, each separately for retracting the piston rod in the shock absorber or for the Extending the piston rod out of the shock absorber can be provided.

Nachteilig bei dieser Ausbildung ergibt sich, dass insbesondere bei Kolbenstangen mit geringem Durchmesser das Einbauen von zwei Stellelementen, wie Stange und diese umgebendes Rohr, äußerst filigran aufgebaut werden müssen. Sofern dieses nicht der Fall ist, wird die Kolbenstange zu stark geschwächt. Es ist jedoch jeweils zu berücksichtigen, dass die erforderlichen Stellkräfte vom äußeren Ende der Kolbenstange bis zum Bereich des Dämpfungskolbens übertragen werden müssen, ohne dass es zu Klemmungen, Reibungen oder extrem großen Verdrehungen kommt.A disadvantage of this training it turns out that especially with piston rods with a small diameter the installation of two control elements, such as a rod and the surrounding one Pipe, extremely delicate have to be built. If this is not the case, the piston rod is weakened too much. It However, it must be taken into account that the required actuating forces from the outer end of the Transfer the piston rod to the area of the damping piston Need to become, without jamming, friction or extremely large twists comes.
Der Erfindung liegt die Aufgabe zugrunde, die vorbeschriebenen Nachteile zu beheben und eine einfache Verstelleinrichtung zu finden, die eine sichere und kontrollierbare Verstellung der Stelleinrichtungen ermöglicht. Die vorstehende Aufgabe wird mit einer Vorrichtung mit den Merkmalen des Anspruchs 1 gelöst. Vorteilhafte Aus- und Weiterbildungen sind in den Ansprüchen 2 bis 9 beschrieben.The invention is based, which Fix the disadvantages described above and a simple adjustment device to find the safe and controllable adjustment of the Actuators enabled. The above object is achieved with a device with the features of claim 1 solved. Advantageous training and further training are in claims 2 to 9 described.
Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, dass mit einfachen Mitteln eine Verstellvorrichtung geschaffen wurde, die es erlaubt, auf einfache Art und Weise zwei verschiedene Stelleinrichtungen zu bedienen. Dieses hat auch besonders dann Vorteile, wenn eine derartige Ausbildung durch Reglements, beispielsweise bei Sportfahrzeugen, gefordert wird.The advantages achieved with the invention consist in particular that with simple means an adjusting device was created, which allows two in a simple manner to operate various control devices. This also has special advantages if such training is based on regulations, for example in sports vehicles.
