Abstract
Description
Die Erfindung betrifft eine Bremsanlage mit einer Einrichtung zur Regelung des Brems- und Antriebsschlupfes und/oder zur Fahrdynamikregelung nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a brake system with a device for controlling the brake and drive slip and / or for driving dynamics control according to the preamble of the claim 1.
Aus der
Bei Bremsanlagen der angegebenen Art ist es von großer Bedeutung, dass keine Schmutzpartikel, insbesondere Festkörperpartikel, in den Arbeitsbereich der Ein- und Auslassventile gelangen, da sonst mit Ablagerungen oder gar einer Beschädigung der empfindlichen Ventilelemente zu rechnen ist, die zu einer Funktionsbeeinträchtigung führen können. Hierbei sind insbesondere Schmutzpartikel mit metallischem Ursprung von Bedeutung, welche in der Regel nicht mit handelsüblichen Filterelementen zurückgehalten werden können, da entweder das Filternetz nicht engmaschig genug ausgelegt werden kann oder das Filterelement aufgrund von Schneid-, Kriech- oder Durchschlagwirkung dem harten metallischen Schmutzpartikeln nicht zu widerstehen vermag. Der Ursprung solcher filtergängigen Schmutzpartikel ist vielschichtig. Beispielsweise können derartige metallische Schmutzpartikel durch fertigungs- als auch wartungstechnische Mängel über die Bremsflüssigkeit zu den sensiblen Stellen gelangen. Überwiegend handelt es sich dabei um eine quantitativ begrenzte Schmutzpartikelansammlung. Unter gewissen konstruktiven Voraussetzungen, beispielsweise bei Verwendung einer Zahnradpumpe, deren von der Bremsflüssigkeit umspülte Zahnflanken einem stetigen Verschleiß unterliegen, gelangt hingegen auf Dauer metallischer Abrieb in großen Schmutzpartikelmengen in die Bremsflüssigkeit, die von den schmutzempfindlichen Stellen der Bremsanlage fernzuhalten sind.For brake systems of the specified Kind of it's great Meaning that no dirt particles, especially solid particles, get into the working area of the intake and exhaust valves, otherwise with deposits or even damage to the sensitive valve elements can be expected, which can lead to a functional impairment. Here are particular Dirt particles with a metallic origin that matter usually not with commercially available Filter elements retained can be because either the filter network is not designed closely enough can or the filter element due to cutting, creep or Penetration effect of the hard metallic dirt particles not can withstand. The origin of such filterable dirt particles is multi-layered. For example, such metallic Dirt particles due to manufacturing and maintenance defects in the brake fluid get to the sensitive places. Mostly it is thereby a quantitatively limited accumulation of dirt particles. Under certain constructive requirements, for example when using a Gear pump, the tooth flanks of which are washed by the brake fluid are subject to constant wear, on the other hand, metallic abrasion in large quantities of dirt particles occurs over the long term into the brake fluid, to keep them away from the dirt-sensitive areas of the brake system are.
Daher ist es die Aufgabe der vorliegenden Erfindung, eine Bremsanlage der angegebenen Art derart zu verbessern, dass eine Verunreinigung der schmutzempfindlichen Stellen durch filtergängige Festkörperpartikel vermieden wird.It is therefore the object of the present invention to improve a brake system of the type specified in such a way that contamination of the dirt-sensitive areas by filter-accessible solid particles is avoided.
Diese Aufgabe wird erfindungsgemäß für eine Bremsanlage der angegebenen Art mit den kennzeichnenden Merkmalen des Patentanspruchs 1 gelöst.This object is achieved for a brake system of the specified type with the characterizing features of patent claim 1 solved.
Weitere Merkmale, Vorteile und Anwendungsmöglichkeiten der Erfindung gehen im nachfolgenden aus den Unteransprüchen und der Beschreibung mehrerer Ausführungsbeispiele anhand von Zeichnungen hervor.Other features, advantages and possible applications the invention go from the dependent claims and the description of several exemplary embodiments based on drawings.
