Abstract
Geregeltes Bremssystem mit einer exzentergetriebenen Kolbenpumpe, die einen Kolben (3) aufweist, der in einem Gehäuse (1) geführt ist, enthaltend einen Einlasskanal (6) und einen Auslasskanal (7) sowie ein Ventil, insbesondere Ein- oder Auslassventil, wobei das Ventil einen federvorgespannten Ventilkörper (19), einen Ventiltopf (14) mit einem Ventilsitz (18) für den Ventilkörper (19) sowie einen Ventildeckel (15) aufweist, an dem sich eine Schließfeder (20) zur Federvorspannung von dem Ventilkörper (19) abstützt, dadurch gekennzeichnet, dass der Ventildeckel (15) und der Ventiltopf (14) zur Bildung einer Ventilkapsel formschlüssig miteinander verbördelt sind, dass der Kolben (3) in einer Stufenbohrung (2) mit mehreren Stufen vom Gehäuse (1) geführt ist, und dass der Kolben (3) ein durchgehender, glatter Kreiszylinder ist.Regulated brake system with an eccentric piston pump which has a piston (3) which is guided in a housing (1), containing an inlet channel (6) and an outlet channel (7) and a valve, in particular an inlet or outlet valve, the valve has a spring-preloaded valve body (19), a valve pot (14) with a valve seat (18) for the valve body (19) and a valve cover (15) on which a closing spring (20) is supported for spring preloading by the valve body (19), characterized in that the valve cover (15) and the valve pot (14) are positively crimped to form a valve capsule, that the piston (3) is guided in a stepped bore (2) with several steps from the housing (1), and that the Piston (3) is a continuous, smooth circular cylinder.
Description
Die Erfindung betrifft ein geregeltes Bremssystem mit einer exzentergetriebenen Kolbenpumpe nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a controlled brake system with an eccentric-driven piston pump according to the preamble of patent claim 1.
Die Erfindung geht daher aus von einem Bremssystem mit einer exzentergetriebenen Kolbenpumpe der sich aus dem Oberbegriff des Anspruchs 1 ergebenden Gattung.The invention is therefore based on a brake system with a Exzentergetriebenen piston pump resulting from the preamble of claim 1 genus.
Aus der
Die Aufgabe der Erfindung ist es, die Ausgestaltung eines mit einer Kolbenpumpe versehenen Bremssystems der angegebenen Art derart abzuändern, dass sie preiswerter und einfacher herstellbar ist.The object of the invention is to modify the design of a provided with a piston pump brake system of the specified type such that it is cheaper and easier to produce.
Die Erfindung wird für ein Bremssystem der angegebenen Art durch die sich aus dem kennzeichnenden Teil des Anspruchs 1 ergebende Merkmalskombination gelöst.The invention is achieved for a brake system of the type indicated by the combination of features resulting from the characterizing part of claim 1.
Eine Vereinfachung des erfindungsgemäßen Ventiltopfes ergibt sich durch die Verwendung der Merkmalskombination nach Anspruch 2. Dabei sind Topf und/oder Deckel aus Blech geformt. Die Verbindung geschieht erfindungsgemäß durch einen Bördelvorgang derart, dass der Deckel mit dem Topf druckdicht verbunden ist. Der Topf ist als Blechteil sehr einfach herzustellen. Er kann aber auch durch ein Schlagteil gebildet sein, bei dem nicht ein Blech sondern ein geeigneter Metallkörper die gewünschte Topfform durch geeignete Verformungskräfte erhält.A simplification of the valve pot according to the invention results from the use of the feature combination according to
Eine besonders platzsparende Anordnung für das Ventil ergibt sich durch die Merkmalskombination nach Anspruch 3. Danach wird der verschlossene Ventiltopf in eine geeignete Bohrung innerhalb des Pumpengehäuses eingefügt und dort durch Verstemmen dichtend gehalten.A particularly space-saving arrangement for the valve results from the combination of features according to
Dabei kann in einer Weiterbildung der Erfindung gemäß Anspruch 4 die den Pumpenkolben zurückführende Rückholfeder sich mit ihrem anderen Ende an der dem Kolben zugewandten Bodenseite des Topfes abstützen. Zur Vereinfachung ist der Kolben als glatter Kreiszylinder ausgebildet, der mit einer entsprechenden Kolbenbohrung dichtend geführt ist. Es wird somit keine Dichtung an dem Kolben selbst, sondern in den Führungswänden des Pumpenzylinders vorgesehen. So weit ein Filter oder eine Membran in den Strömungskreis der Pumpe eingefügt werden soll, empfiehlt sich in Weiterbildung der Erfindung die Merkmalskombination nach Anspruch 5. Danach wird insbesondere in dem pumpenseitigen Eingang des Ausgangsventils ein vorzugsweise topfförmiges Filter befestigt.In this case, in a development of the invention according to claim 4, the return spring, which returns the pump piston, is supported at its other end on the bottom side of the pot facing the piston. For simplicity, the piston is designed as a smooth circular cylinder, which is sealingly guided with a corresponding piston bore. Thus, no seal is provided on the piston itself, but in the guide walls of the pump cylinder. As far as a filter or a membrane to be inserted into the flow circuit of the pump, it is recommended in a further development of the invention, the combination of features according to claim 5. Thereafter, a preferably cup-shaped filter is attached in particular in the pump-side input of the output valve.
Ein besonderer Vorteil der Erfindung lässt sich dadurch erzielen, dass man die Merkmale nach Anspruch 6 anwendet. Danach wird der Innenraum der Ventilkapsel derart ausgestaltet, dass die Kapsel gleichzeitig als Dämpfungskammer für den Auslasskanal der Pumpe dienen kann. Der Auslass aus der Kammer ist wie weiter unten noch beschrieben wird, durch eine Blende verschlossen, wobei sich die Blendenöffnung durch eine kleine Bohrung in der Mantelfläche des Ventiltopfes gebildet ist, an die sich dann der Auslasskanal im Pumpengehäuse anschließt.A particular advantage of the invention can be achieved by applying the features of
Somit ergibt sich durch die Erfindung eine kastengünstige Einheit von Druckventil, Dämpfungskammer und Blende. Ein Ausführungsbeispiel der Erfindung wird danach anhand der Zeichnung dargestellt. Darin zeigt:Thus, the invention results in a box-friendly unit of pressure valve, damping chamber and aperture. An embodiment of the invention will be illustrated with reference to the drawing. It shows:
