Abstract

The pressure medium storage (1) has a cylindrical bore (2) representing the housing for a pressure medium storage. The bore receives a piston (5), which is supported by a spring (4) and a closing cover (3). With the reception of pressure the piston moves from its front end position against a contact surface (14) of the guide bush (6). The resulting volume is in the position, to store liquid and gaseous media, and then re-deliver this as required. The can shaped cover (4) with the integrated guide bush (6) is designed in one piece. The piston (5) is supported by an outer-lying spring (4). The sealing elements (7,8) consist of watertight, but air permeable plastics. The piston (5) is made of plastics.

Description

Die Erfindung betrifft einen Druckmittelspeicher, insbesondere zum Einsatz in Hydraulikaggregaten von elektronischen Bremsen­ systemen für Kraftfahrzeuge. Aus der DE 42 02 905 A1 ist ein Druckmittelspeicher für hydraulische Bremsanlagen bekannt, dessen Kolben in einer Zylinderbohrung axial beweglich einge­ baut und mit einer Feder gegen eine Verschlußkappe mit der die Zylinderbohrung verschlossen ist, abgestützt wird. Die Ver­ schlußkappe ist mittels eines Sprengrings in der Zylinderboh­ rung befestigt und durch eine Abdeckkappe verdeckt. Der Kolben ist als topfförmiges Bauteil ausgeführt, bei dem die dem Topf­ boden abgewandten äußeren Topfwände als Kolbenführung am Um­ fang der Zylinderbohrung anliegen. Die Feder ist in den Topf eingelegt und wird durch seine Innenwände geführt. Die Abdich­ tung des Kolbens gegenüber der Gehäusewand geschieht mittels eines Dichtrings.The invention relates to a pressure medium reservoir, in particular for use in hydraulic units of electronic brakes systems for motor vehicles. From DE 42 02 905 A1 is a Pressure fluid accumulator known for hydraulic brake systems, whose piston is axially movable in a cylinder bore builds and with a spring against a cap with the Cylinder bore is closed, is supported. The Ver end cap is by means of a snap ring in the cylinder bore fixed and covered by a cover cap. The piston is designed as a pot-shaped component in which the pot outer pot walls facing away from the floor as a piston guide on the um beginning of the cylinder bore. The feather is in the pot inserted and is guided through its inner walls. The Abdich tion of the piston against the housing wall is done by means of a sealing ring.

Durch die Topfform des Kolbens wird in radialer Richtung in der Dicke der Topfwände Bauraum benötigt, der bei Integration des Druckmittelspeichers in ein Hydraulikaggregat dieses ver­ größert und damit erschwert. Die aus Stahl gefertigten Ein­ zelteile des Druckmittelspeichers erhöhen zusätzlich sein Ge­ wicht.The pot shape of the piston is in the radial direction The thickness of the pot walls requires installation space, that for integration of the pressure fluid reservoir in a hydraulic unit this ver enlarged and thus difficult. The made of steel parts of the pressure fluid reservoir also increase its ge important.

Aufgabe der Erfindung ist es daher, einen leichten und auf kleinstem Raum in ein Hydraulikaggregat integrierbaren Druck­ mittelspeicher anzubieten. The object of the invention is therefore a light and The smallest space that can be integrated into a hydraulic unit to offer medium storage.  

Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Hauptanspruchs und der Unteransprüche gelöst.This object is achieved by the characterizing Features of the main claim and the subclaims solved.

Die Druckkraft aufnehmenden und weiter leitenden Bauteile sind im Bauraum der für die Druckaufnahme notwendigen Feder ange­ ordnet. Der Kolben wird durch einen im Zentrum der Verschie­ beachse angeordneten Führungszapfen geführt. Die den Führungs­ zapfen aufnehmende Führungsbuchse ist in die Schraubenfeder hineingestülpt. Der für die Führungselemente benötigte Bauraum ist somit in den in der Feder vorhandenen freien Raum verlegt und benötigt keinen zusätzlichen Raum. Um weiteres Gewicht zu sparen, ist der Kolben aus Kunststoff und der topfförmige mit integrierter Führungsbuchse einteilig ausgestattete Verschluß­ deckel als tiefgezogenes Blechteil ausgeführt.The pressure-absorbing and further conductive components are in the installation space of the spring necessary for pressure absorption arranges. The piston is moved through one in the center Note the guide pin arranged. The leadership Pin-receiving guide bush is in the coil spring put in. The installation space required for the guide elements is thus moved to the free space in the spring and doesn't need any additional space. To add weight save, the piston is made of plastic and the cup-shaped one Integrated guide bushing, one-piece closure Cover designed as a deep-drawn sheet metal part.

Weitere Vortei­ le, Merkmale und Einzelheiten der Erfindung werden anhand von Zeichnungen und der folgenden Ausführungsbeispiele erläutert.Another advantage le, features and details of the invention are based on Drawings and the following embodiments explained.

Fig. 1 zeigt einen Längsschnitt durch eine Ausführungsform des Duckmittelspeichers 1. Die dargestellte Ausführungsform be­ steht aus einem in eine Zylinderbohrung 2 eingeführten Kolben 5, der mittels einer Schraubenfeder 4 gegen einen Verschluß­ deckel 3 abgestützt wird. An dem aus Kunststoff ausgeführten Kolben ist ein Führungsdorn 11 angegossen, an dessen freiem Ende eine Nut zur Aufnahme eines Dichtelementes 8, hier eines geteilten Kunststoffringes, eingelassen ist. Am Rand der Kol­ bendruckfläche 9 ist ebenfalls eine Nut zur Aufnahme eines Dichtelementes 7 eingegossen. Als weitere vorteilhafte Alter­ native kann das Dichtelement 7 direkt am Kolben einvulkani­ siert werden. Fig. 1 shows a longitudinal section through an embodiment of the Duck accumulator 1. The illustrated embodiment be consists of an inserted into a cylinder bore 2 piston 5 , which is supported by a coil spring 4 against a closure cover 3 . On the piston made of plastic, a guide pin 11 is cast, at the free end of which a groove for receiving a sealing element 8 , here a split plastic ring, is embedded. At the edge of the pressure surface 9 Kol also a groove for receiving a sealing element 7 is cast. As a further advantageous alternative, the sealing element 7 can be vulcanized directly onto the piston.

Um Spritzgrade an Kontaktflächen zu vermeiden, ist die Spritz­ gußform für den Kolben oberhalb der Kontaktfläche 12 radial geteilt.In order to avoid degrees of injection at contact surfaces, the injection mold for the piston above the contact surface 12 is divided radially.

Der Verschlußdeckel 3 ist mit der Führungsbuchse 6 einteilig aus einer Blechronde tiefgezogen. Am oberen Rand der Zylinder­ bohrung ist ein Absatz 13 eingearbeitet, in die der Verschluß­ deckel 3 eingesetzt und dann verstemmt wird. An der der Ver­ schlußseite des Deckels abgewandten Öffnung der Führungsbuchse 6 ist eine Anlagefläche 14 angeformt, die den Endanschlag des Kolbens 5 bei maximalem Hub markiert.The closure cover 3 is deep-drawn in one piece with the guide bush 6 from a sheet metal blank. At the top of the cylinder bore a paragraph 13 is incorporated, in which the closure cover 3 is inserted and then caulked. At the United closing side of the lid opening of the guide bush 6 , a contact surface 14 is formed, which marks the end stop of the piston 5 at maximum stroke.

Fig. 2 zeigt ebenfalls einen Längsschnitt durch eine weitere vorteilhafte Ausführungsform des Druckmittelspeichers 1. Der Aufbau des Speichers ist bis auf das Dichtelement 8 am Füh­ rungsdorn 11 identisch. Das Dichtelement 8 ist in dieser Aus­ führung an das Ende des Führungsdorns 11 angegossen. FIG. 2 also shows a longitudinal section through a further advantageous embodiment of the pressure medium store 1 . The structure of the memory is identical except for the sealing element 8 on the guide pin 11 . The sealing element 8 is cast in this implementation from the end of the guide pin 11 .

Fig. 3 stellt eine weitere Variante der Abdichtung am Füh­ rungsdorn 11 dar. Fig. 3 shows another variant of the seal on the Füh approximately mandrel 11 .
