Abstract

In order, in a diaphragm-type damping capsule for hydraulic systems, to achieve good damping of the vibrations even at high pressure and, with a simple construction, to guarantee reliable force transmission, use is made for the diaphragm of a hardened and tempered spring-steel disc, the line (11) connected to the slave cylinder (10) opening into the centre of the diaphragm-type damping capsule (1) and the pressure-medium line (12) connected to the master cylinder (9) being situated right at the outside. <IMAGE>

Description

Die Erfindung betrifft eine Membrandämpferdose nach dem Oberbegriff des Anspruchs 1.The invention relates to a diaphragm damper can the preamble of claim 1.

Aus der DE-OS 31 03 147 ist eine Membrandämpferdose für gasförmige oder flüssige Brennstoffe bekannt, bei der eine elastomere Membrane verwendet wird und das Medium außermittig zugeführt und um 90° versetzt dazu im Mantelbereich abgeführt wird. Für die Däm­ pfung von Schwingungen in hydrauliscnen Systemen z. B. Antiblockiereinrichtungen oder Kupplungseinrich­ tungen ist eine derartige Vorrichtung jedoch nicht verwendbar, da die elastomere Membrane den dabei auftretenden Drücken nicht standhalten könnte und reißen würde.From DE-OS 31 03 147 is a membrane damper box known for gaseous or liquid fuels, where an elastomeric membrane is used and the medium is fed off-center and offset by 90 ° is carried away in the jacket area. For the dam Checking vibrations in hydraulic systems, e.g. B. anti-lock devices or clutch device but such a device is not can be used because the elastomeric membrane could not withstand occurring pressures and would tear.

Es ist deshalb Aufgabe der Erfindung, eine Mem­ brandämpferdose der eingangs genannten Art so wei­ terzubilden, daß sie auch bei hydraulischen Systemen mit hohem Druck eine gute Dämpfung der Schwingungen erzielt und bei einfachem Aufbau eine sichere Kraft­ übertragung gewährleistet.It is therefore an object of the invention to create a mem firebox of the type mentioned so white terzubilden that they also in hydraulic systems good damping of vibrations at high pressure achieved and with a simple structure a safe force transmission guaranteed.

Die Lösung dieser Aufgabe ist dem kennzeichnenden Teil des Anspruchs 1 zu entnehmen. Vorteilhafte Ausgestaltungen enthalten die Ansprüche 2, 3 und 4.The solution to this problem is the characteristic Part of claim 1. Beneficial Refinements contain claims 2, 3 and 4.

Die Erfindung wird an einem Ausführungsbeispiel erläutert. Es zeigt: The invention is based on an embodiment explained. It shows:  

Fig. 1 eine Membrandämpferdose im Schnitt. Fig. 1 is a membrane damper box in section.

Fig. 2 eine Seitenansicht einer Membrandämpferdose. Fig. 2 is a side view of a membrane damper box.

Fig. 3 eine hydraulische Kupplungsanlage mit Mem­ brandämpferdose. Fig. 3 is a hydraulic clutch system with mem fire damper.

In Fig. 1 und 2 ist die Membrandämpferdose mit 1 bezeichnet. Sie besteht aus einem topfförmigen Gehäuse 2, in dessen Bodenbereich eine Membrane 3 axial frei schwingbar eingeklemmt ist. Im Einspann­ bereich ist ein Dichtring 4 angeordnet. Der Gehäuse­ deckel 5 ist in das Gehäuse 2 eingeschraubt und durch Umbördeln mit ihm verbunden. Er weist eine zentrale Druckmittelleitungsöffnung 6 und eine möglichst weit außen liegende Druckmittelleitungsöffnung 7 auf. Zur Befestigung sind Gewindebohrungen 8 vorgesehen.In Fig. 1 and 2, the diaphragm damper box is designated at 1. It consists of a pot-shaped housing 2 , in the bottom area of which a diaphragm 3 is clamped in an axially freely oscillating manner. In the clamping area, a sealing ring 4 is arranged. The housing cover 5 is screwed into the housing 2 and connected to it by flanging. It has a central pressure medium line opening 6 and a pressure medium line opening 7 that is as far out as possible. Threaded bores 8 are provided for fastening.

Wie aus Fig. 3 ersichtlich, ist die Membrandäm­ pferdose 1 zwischen dem Geberzylinder 9 und dem Nehmerzylinder 10 in der Rohrleitung 11, 12 angeord­ net, wodurch die von der Kupplung (nicht gezeigt) kommenden Schwingungen gedämpft werden. Dabei mündet die mit dem Nehmerzylinder 10 verbundene Druckmit­ telleitung 11 in die Mitte der Membrandämpferdose 1, während die mit dem Geberzylinder 9 verbundene Druckmittelleitung 12 sich möglichst weit außen befindet.As seen from Fig. 3, the Membrandäm pferdose 1 between the master cylinder 9 and the slave cylinder 10 in the pipeline 11, 12 angeord net, whereby the (not shown) of the coupling coming vibrations are damped. In this case, the pressure line 11 connected to the slave cylinder 10 opens into the center of the diaphragm damper socket 1 , while the pressure medium line 12 connected to the master cylinder 9 is located as far out as possible.
