Description

Die Erfindung betrifft einen Bremsdruckgeber, insbesondere für schlupfgeregelte Bremsanlagen, nach dem Oberbegriff des Anspruchs 1.The invention relates to a brake pressure transmitter, in particular for slip-controlled brake systems, according to the generic term of Claim 1.

Einen Bremsdruckgeber der gattungsbildenden Art für schlupf­ geregelte Bremsanlagen ist bereits aus der französischen Pa­ tentanmeldung FR 25 65913 A1 bekannt.A brake pressure transmitter of the generic type for slip regulated brake systems is already from the French Pa tent registration FR 25 65913 A1 known.

Dieser Bremsdruckgeber nimmt den im Bremsdruckgebergehäuse geführten Arbeitskolben mit einer im Druckraum koaxial vor­ gelagerten Kugelventileinrichtung auf, die abhängig vom Hub des Arbeitskolbens eine hydraulische Verbindung zwischen einem Paar in das Bremsdruckgebergehäuse eingesetzten Elektro­ magnetventilen und den Radbremsen herstellt. Ein Druckmittelvorratsbehälter in der Funktion des Nachlaufrau­ mes stützt sich einerseits auf den Elektromagnetventilen, andererseits am Bremsdruckgebergehäuse ab, wobei eine Kanal­ verbindung eine Druckmittelversorgung zwischen dem Nachlaufraum und dem Druckraum herstellt.This brake pressure sensor takes the one in the brake pressure sensor housing guided working piston with a coaxial in the pressure chamber Ball valve device mounted on, depending on the stroke the working piston a hydraulic connection between one Pair of electrical inserted in the brake pressure sensor housing solenoid valves and the wheel brakes. A Pressure fluid reservoir in the function of the trailing roo mes relies on the one hand on the electromagnetic valves, on the other hand on the brake pressure generator housing, with a channel connection a pressure medium supply between the trailing room and the pressure room.

Bei dem vorbeschriebenen Bremsdruckgeber ist es als nicht sonderlich vorteilhaft anzusehen, daß im Bereich der Elektromagnetventile ein erheblicher un­ genützter Leerraum zwischen dem Bremsdruckgebergehäuse und dem Nachlaufraum verbleibt und des weiteren die Elektro­ magnetventile im Betriebszustand einer hohen Betriebs­ temperatur mangels ungenügender Kühlung unterliegen.In the brake pressure sensor described above, it is considered not particularly advantageous to see that in the field of electromagnetic valves a considerable un space used between the brake pressure sensor housing and  the trailing room remains and the electrical solenoid valves in the operating condition of a high operating temperature due to insufficient cooling.

Daher ist es Aufgabe der Erfindung, einen Bremsdruckgeber der genannten Gattung dahingehend zu verbessern, daß einer­ seits eine funktionsoptimierte Bauraumgestaltung im Sinne einer Kompaktbauweise geschaffen wird und andererseits die Betriebstemperatur der Elektromagnetventile verringert bzw. ihre Abwärme genutzt wer­ den kann.It is therefore an object of the invention to provide a brake pressure sensor to improve the aforementioned genus in that one on the one hand, a functionally optimized installation space design in the sense a compact design is created and on the other hand the Operating temperature of the solenoid valves is reduced or their waste heat is used that can.

Diese Aufgabe wird bei dem gattungsgemäßen Bremsdruckgeber durch die sich aus dem kennzeichnenden Teil des Hauptan­ spruchs ergebende Merkmalskombination gelöst. Somit basiert der Grundgedanke der Erfindung auf einer baulichen Vereini­ gung des Nachlaufraumes mit dem Bremsdruckgebergehäuse, wo­ bei die Elektromagnetventile in den Nachlaufraum eingesetzt sind.This task is the generic brake pressure sensor through from the distinctive part of the main part resulting combination of features solved. Thus based the basic idea of the invention on a structural association supply of the trailing space with the brake pressure sensor housing, where used in the solenoid valves in the trailing space are.

Die weitere Ausgestaltung des Erfindungsgedankes sieht vor, daß das Bremsdruckgebergehäuse einen hydraulischen Hilfs­ druckraum aufnimmt, der von weiteren im Bremsdruckgeberge­ häuse integrierten Elektromagnetventilen hydraulisch steuer­ bar ist, wodurch beispielsweise durch die Integration eines hydraulischen Verstärkers im Bremsdruckgebergehäuse und des­ sen mittels Elektromagnetventilen gesteuerten Hilfsdrucks ein baulich hochkomprimiertes Bremsgerät verwirklichen läßt.The further development of the inventive concept provides that the brake pressure sensor housing a hydraulic auxiliary takes up pressure space, that of others in the brake pressure generator Hydraulic control housing integrated solenoid valves bar, which means, for example, by integrating a hydraulic amplifier in the brake pressure sensor housing and auxiliary pressure controlled by solenoid valves realizes a structurally highly compressed braking device.

Zum Zwecke der Druckmittelsteuerung zwischen dem Nachlauf­ raum und dem Druck- bzw. Hilfsdruckraum, sowie auch zur Druckmittelversorgung der Radbremse ist vorgesehen, die be­ reits schaltungstechnisch gebräuchlichen stromlos auf Durch­ laß geschalteten Einlaßventile und stromlos geschlossen ge­ schalteten Auslaßventile zu verwenden.For the purpose of pressure medium control between the wake space and the pressure or auxiliary pressure space, as well as for  Pressure medium supply of the wheel brake is provided, which be already used in terms of circuit technology currentless on through leave switched inlet valves and closed when de-energized switched exhaust valves to use.

In der weiteren Ausbaustufe des Bremsdruckgebers ist vorge­ sehen, die druckmittelsteuernden Elektromagnetventile jeweils in baulicher Integration mit dem Druckraum, dem Hilfsdruckraum und dem Nachlaufraum hydraulisch zu verbinden, wobei alle druckmittelführenden Räume im Bremsdruckgebergehäuse unter­ gebracht sind.In the further stage of expansion of the brake pressure sensor is pre see the pressure control solenoid valves each in structural integration with the pressure room, the auxiliary pressure room and hydraulically connect the trailing space, all spaces in the brake pressure transmitter housing under are brought.

Weitere Präzisierungen des Erfindungsgedankens gehen aus den Ansprüchen 5 bis 7 hervor, wonach der Nachlaufraum aus den die Elektromagnetventile umhüllenden Freiräumen gebildet ist. Dabei ist es aus sicherheitsrelevanten Erkenntnissen vor­ teilhaft, die druckmittelspeichernden Freiräume mittels Zwischenwänden hydraulisch voneinander zu trennen, um durch separat gefüllte Nachlaufräume beim Auftreten einer Leckage in einem Nachlaufraum oder den angeschlossenen Räumen die Druckmittelversorgung der Rad­ bremsen zu gewähr­ leisten.Further clarifications of the inventive concept are given in the Claims 5 to 7, according to which the trailing space from the the free spaces enveloping the solenoid valves is formed. It is based on security-relevant findings partial, by means of the pressure medium-storing free spaces Hydraulically separate partitions from each other in order to be able to fill the If there is a leak in a trailing room or the connected rooms, the pressure medium supply to the wheel to brake Afford.

Gemäß Anspruch 8 und 9 ist es zweckmäßig, die Nachlaufräume einstückig mit dem Bremsdruckgebergehäuse zu vereinigen, um die Anzahl der leckagegefährdeten Verbindungsstellen zu re­ duzieren und die Elektromagnetventile zur besseren Kühlung möglichst vollständig mit dem Druckmittel zu umspülen.According to claims 8 and 9, it is expedient to the trailing rooms integrally with the brake pressure sensor housing to the number of connection points at risk of leakage reduce and the solenoid valves for better cooling flush as completely as possible with the pressure medium.

Weitere Ziele, Merkmale, Vorteile und Anwendungsmöglichkei­ ten der vorliegenden Erfindung ergeben sich aus der nachfol­ genden Beschreibung eines Ausführungsbeispieles anhand der Zeichnung.Further goals, features, advantages and possible applications th of the present invention result from the following  ing description of an embodiment based on the Drawing.

Es zeigt die Zeichnung im Längsschnitt sche­ matisch skizziert einen Bremsdruckgeber in Tandembauweise, der in baulicher Vereinigung im Bremsdruckgebergehäuse 1 den Druckraum 6, den Nachlaufraum 3 und den Hilfsdruckraum 4 des hydraulischen Verstärkers 5 wiedergibt. Das Bremsdruckgeber­ gehäuse 1 ist aus einem Block hergestellt, der in koaxialer Anordnung sowie in Reihe längs hintereinander geschaltet den Hilfsdruckraum 4 mit dem Hilfsdruckkolben und dem Druckraum 6 mit den beiden Arbeitskolben aufnimmt. In der Querrichtung zur Längsachse des Bremsdruckgebergehäuses 1 sind mehrere als Einlaßventile und Auslaßventile ausgeführte Elektro­ magnetventile 2 auf die Druckmittelräume 6 gerichtet, die das Druckmittel direkt aus den jeweils ein Elektromagnet­ ventilpaar aufnehmenden Nachlaufräumen 3 erhalten. Der Nach­ laufraum 3 ist mittels den quer zur Bremsdruckgeberlängs­ achse verlaufenden Zwischenwänden 7 in mehrere separate, je­ weils einem Bremsdruckkreis zugeordnete Nachlaufräume 3 un­ terteilt. Die um die Elektromagnetventile 2 befindlichen und von den benachbarten Wänden des Bremsdruckgebergehäuses 1 begrenzten Zwischenräume bzw. Freiräume nehmen das Druckmit­ tel auf, um die Elektromagnetventile 2 direkt zu versorgen und zu kühlen. Zweckmäßigerweise ist der Nachlaufraum 3 von einem Deckel 8 verschlossen, der eine mit einer Warneinrich­ tung versehenen Einfüllverschraubung 9 aufnimmt. Ein am Bremsdruckgebergehäuse 1 oder wahlweise am Deckel 8 angeord­ neter Stecker 10 ermöglicht die Ansteuerung der Elektro­ magnetventile 2. Weiterhin ist auf bereits bekannte Weise eine permanente Druckmittelversorgung des Druckraumes 6 bzw. des Hilfsdruckraumes 4 mittels Nachlaufkanäle 11 sicherge­ stellt, um unabhängig von der elektrischen Ventilansteuerung der Radbremsen fußkraftproportionales Druckmittel einsteuern zu können.It shows the drawing in longitudinal section schematically outlines a brake pressure sensor in tandem construction, which in structural association in the brake pressure sensor housing 1 represents the pressure chamber 6 , the trailing chamber 3 and the auxiliary pressure chamber 4 of the hydraulic booster 5 . The brake pressure sensor housing 1 is made from a block that accommodates the auxiliary pressure chamber 4 with the auxiliary pressure piston and the pressure chamber 6 with the two working pistons in a coaxial arrangement and connected in series in series. In the transverse direction to the longitudinal axis of the brake pressure transducer housing 1 , a plurality of solenoid valves 2 designed as inlet valves and outlet valves are directed toward the pressure medium spaces 6 , which receive the pressure medium directly from the trailing spaces 3 receiving a pair of solenoid valves. After the running space 3 is divided by means of the transverse to the brake pressure longitudinal axis partition walls 7 into several separate, each because a brake pressure circuit associated trailing spaces 3 un. The spaces or free spaces located around the solenoid valves 2 and delimited by the adjacent walls of the brake pressure sensor housing 1 take up the Druckmit tel in order to supply and cool the solenoid valves 2 directly. Advantageously, the trailing chamber 3 is closed by a cover 8 which receives a filler screw 9 provided with a warning device. A on the brake pressure sensor housing 1 or optionally on the cover 8 angeord Neten connector 10 enables the control of the solenoid valves 2nd Furthermore, a permanent pressure medium supply to the pressure chamber 6 or the auxiliary pressure chamber 4 by means of follow-up channels 11 is provided in a known manner in order to be able to control pressure medium proportional to the foot force independently of the electrical valve actuation of the wheel brakes.

Durch die integrierte Bauweise des Bremsdruckgebers ist eine kompakte Anordnung aller funktionsrelevanten Bauteile ge­ währleistet. Durch die Positionierung der Elektromagnet­ ventile 2 im Nachlaufraum 3 und der Druckmittelspeicherung in den die Elektromagnetventilen 2 umgebenden Freiräumen ist ferner eine erhebliche Senkung der Ventilbetriebstemperatur sichergestellt, so daß über die platzsparende, verbilligte Bauweise des Bremsdruckgebers hinaus, die Funktionssicher­ heit bzw. das Leistungsvermögen der Anlage gesteigert werden kann.The integrated design of the brake pressure sensor ensures a compact arrangement of all functionally relevant components. The positioning of the electromagnet 2 valves in the supply chamber 3 and the pressure medium storage in which the solenoid valves 2 surrounding spaces is further ensured a significant reduction in the valve operating temperature so that uniform the function safely to the space-saving, reduced-price construction of the braking pressure generator addition or the performance of the plant can be increased.
