Abstract
Description
Die Erfindung betrifft einen hydraulischen und/oder pneumatischen Stoßdämpfer mit Feststellfunktion, wie er z. B. für Verstell- oder Feststelleinrichtungen an Kraftfahrzeugen o. ähnlichen Objekten insbesondere als Dämpfer/Feststeller für Türen, Motorhauben usw. verwendet wird.The invention relates to a hydraulic and / or pneumatic shock absorber Locking function, such as. B. for adjustment or locking devices Motor vehicles or similar objects, in particular as dampers / locks for Doors, hoods, etc. is used.
Diese Stoßdämpfer mit Feststellfunktion müssen als Massenartikel kostengünstig herstellbar sein und unterliegen hohen Qualitätsanforderungen. Es besteht daher Bedarf nach einer gegenüber heutigen Ausführungen vereinfachten und verbilligten Lösung.This shock absorber with locking function must be inexpensive as a mass article be producible and are subject to high quality requirements. It therefore exists Need for a simplified and cheaper compared to today's designs Solution.
Die bisherigen Lösungen, so auch der in der DE 44 31 626 A1 offenbarte Feststeller zum Feststellen zweier relativ zueinander beweglicher Objekte, haben den großen Nachteil, daß sie sich nur mit einem enormen konstruktiven, fertigungstechnischen und somit kostenintensiven Aufwand herstellen lassen.The previous solutions, including the lock disclosed in DE 44 31 626 A1 to detect two objects that are movable relative to each other, have the big one Disadvantage that they are only with an enormous constructive, manufacturing technology and thus have cost-intensive production.
Es ist daher Aufgabe der Erfindung, einen gattungsgemäßen hydraulischen und/oder pneumatischen Stoßdämpfer mit Feststellfunktion derart zu gestalten, daß er vereinfachter, kostengünstiger und aus wenigen Teilen herstellbar ist, ohne die Vorteile bisher bekannter Stoßdämpfer aufzugeben.It is therefore an object of the invention to provide a generic hydraulic and / or pneumatic shock absorber with locking function so that it is simpler, cheaper and can be produced from a few parts without the Give up advantages of previously known shock absorbers.
Diese Aufgabe ist bei einem Stoßdämpfer mit Feststellfunktion nach dem Oberbegriff des Anspruchs 1 mit den Merkmalen des Kennzeichens des Anspruchs 1 gelöst worden, wobei vorteilhafte Weiterbildungen mit den Unteransprüchen angegeben sind.This task is for a shock absorber with a locking function according to the generic term of claim 1 with the features of the characterizing part of claim 1 solved have been given, advantageous developments with the dependent claims are.
Ein Ausführungsbeispiel der Erfindung ist in zwei Zeichnungen (Fig. 1 und 2) dargestellt und wird nachfolgend beschrieben.An embodiment of the invention is shown in two drawings ( Fig. 1 and 2) and is described below.
Die Fig. 1 der Zeichnung zeigt einen hydraulischen und/oder pneumatischen Stoßdämpfer mit Feststellfunktion 1 bestehend aus einem Zylinder 2, einem Kolben 3 mit Kolbenstange 4, im Kolben 3 angeordnete Überströmöffnung 5, deren wirksamer Querschnitt durch eine dämpfende Ventileinrichtung 6 stellkraftabhängig veränderbar ist. Fig. 1 of the drawing shows a hydraulic and / or pneumatic shock absorber with locking function 1 consisting of a cylinder 2 , a piston 3 with piston rod 4 , overflow opening 5 arranged in the piston 3 , the effective cross section of which can be changed as a function of the actuating force by means of a damping valve device 6 .
Mit einem solchen Stoßdämpfer mit Feststellfunktion 1 läßt sich beispielsweise die Öffnungsbewegung einer Fahrzeugtür oder einer Klappe in bekannter Weise begrenzen oder beenden (in allen möglichen Öffnungs-/Schließstellungen). Bei diesem Stoßdämpfer mit Feststellfunktion ist nun vorgegeben, daß die Ventileinrichtung 6 aus einem der Überströmöffnung 5 querschnittsmäßig angepaßten Elastomerformkörper 7 gebildet ist.With such a shock absorber with locking function 1 , for example, the opening movement of a vehicle door or a flap can be limited or ended in a known manner (in all possible opening / closing positions). In this shock absorber with a locking function, it is now specified that the valve device 6 is formed from an elastomer molded body 7 which is cross-sectionally adapted to the overflow opening 5 .
Hierdurch wird erreicht, daß bei einer Bewegung der Kolbenstange das unter dem Bewegungsdruck stehende Medium wie z. B. Hydraulikflüssigkeit und/oder ein Gas in die Überströmöffnung 5 eintreten kann, dort den Elastomerkörper 7 elastisch zusammendrückt, wie in Fig. 2 dargestellt ist, und den Preßsitz anhebt. Hierdurch entsteht zwischen einer Zylinderwand 8 und dem Elastomerkörper 7 ein Überströmöffnungsquerschnitt 9 mit der bekannten Wirkung, daß ein Medium von der einen Zylinderseite 10 zur anderen Seite 11 überströmen kann und umgekehrt (Volumenänderungen in den Zylinderseiten 10 und 11, zum Beispiel aufgrund von Temperatureinflüssen oder der Stangenbewegung, werden durch den Volumenausgleichs-Einsatz 16 kompensiert).This ensures that when the piston rod moves, the medium under the movement pressure, such as. B. hydraulic fluid and / or a gas can enter the overflow opening 5 , there elastically compresses the elastomer body 7 , as shown in Fig. 2, and raises the press fit. This creates an overflow opening cross section 9 between a cylinder wall 8 and the elastomer body 7 with the known effect that a medium can flow over from one cylinder side 10 to the other side 11 and vice versa (volume changes in the cylinder sides 10 and 11 , for example due to temperature influences or the Bar movement, are compensated by the volume compensation insert 16 ).
Es ist zweckmäßig, wenn die Überströmöffnung 5 als in Kolbenwirkrichtung ausgeführtes Zylinderloch angeordnet ist, in welches ein kugelförmiger Elastomerformkörper 7 beispielsweise mit leichtem Preßsitz eingesetzt und gegen axiales Verstellen gesichert ist oder alternativ, wenn die Überströmöffnung 5 als in Kolbenwirkrichtung ausgeführtes Profilloch 12 angeordnet ist, in welches ein mit gleichem Profil ausgeführter Elastomerformkörper 7 beispielsweise mit leichtem Preßsitz eingesetzt und gesichert ist.It is expedient if the overflow opening 5 is disposed as the running in piston effective direction of the cylinder hole in which a ball-shaped elastomeric forming body 7 is used, for example with slight press fit and is secured against axial displacement, or alternatively, if the overflow opening 5 is disposed as the running in piston effective direction profile hole 12 in which an elastomer molded body 7 with the same profile is inserted and secured, for example with a light press fit.
Der Elastomerformkörper 7 kann aus einem geschäumten Elastomer bestehen, es kann für eine besondere Dämpferabstimmung jedoch auch vorteilhaft sein, wenn der Elastomerformkörper als Hohlkörper 13 ausgeführt ist. Der Elastomerformkörper 7 kann durch in Fig. 1 dargestellte Absätze 14 in der Überströmöffnung axial gesichert sein, vorteilhafter für eine kostengünstige Fertigung kann es jedoch sein, wenn der Elastomerformkörper 7 durch in die Überströmöffnung 5 eingesetzte Anschlagsicherung 15 gesichert ist, wie Fig. 2 zeigt. The molded elastomer body 7 can consist of a foamed elastomer, but it can also be advantageous for a special damper adjustment if the molded elastomer body is designed as a hollow body 13 . The molded elastomer body 7 can be axially secured in the overflow opening by means of shoulders 14 shown in FIG. 1, but it can be more advantageous for cost-effective production if the molded elastomer body 7 is secured by stop safety device 15 inserted into the overflow opening 5 , as shown in FIG. 2.
