Description
Die Erfindung betrifft ein pumpenloses Kraftfahrzeugbremssystem, insbesondere für Krafträder, nach dem Oberbegriff des Patentanspruchs 1.The The invention relates to a pumpless motor vehicle brake system, in particular for motorcycles, after the preamble of claim 1.

Bei Krafträdern des unteren Preissegments besteht daher im allgemeinen die Gefahr, dass bei schlechten, insbesondere nassen Straßenverhältnissen und einem abrupt eingeleiteten Bremsvorgang eine Blockiertendenz des Vorderrades vorhanden ist. Im schlimmsten Fall kommt es zum Blockieren des Vorderrades und somit zum Verlust der Seitenführungskraft. Gerade bei Zweirädern führt mangelhafte Fahrstabilität zu einem extrem kritischen Zustand und stellt mit Blick auf das Sturzrisiko ein hohes Gefahrenpotential für den Fahrer dar.at motorcycles lower price segment is therefore generally at risk of that in bad, especially wet road conditions and an abruptly initiated Braking a blocking tendency of the front wheel is present. in the worst case it comes to blocking the front wheel and thus to the loss of cornering power. Especially with two-wheelers leads to poor driving stability extremely critical condition and poses with a view to the risk of falling a high risk potential for the driver
Daher ist es die Aufgabe der vorliegenden Erfindung, ein kostengünstiges, funktionssicheres Kraftfahrzeugbremssystem mit Bremsschlupfregelung zu entwickeln, das sich besonders gut für den Einsatz in Krafträdern des unteren und mittleren Preisniveaus eignet.Therefore It is the object of the present invention, an inexpensive, reliable motor vehicle brake system with brake slip control to develop, which is particularly good for use in motorcycles of the lower and middle price levels.
Diese Aufgabe wird für eine Kraftfahrzeugbremssystem der angegebenen Art mit den kennzeichnenden Merkmalen des Patentanspruchs 1 gelöst.These Task is for a motor vehicle brake system of the type specified with the characterizing Characteristics of claim 1 solved.
Weitere Merkmale und Vorteile der Erfindung gehen aus den Unteransprüchen sowie aus der nachfolgenden Beschreibung eines Ausführungsbeispiels anhand zweier Zeichnungen hervor.Further Features and advantages of the invention will become apparent from the dependent claims and from the following description of an embodiment with reference to two Drawings forth.

Grundsätzlich gilt für die Funktionsweise:
- 1. Eine Blockierneigung einer
der beiden Radbremsen
5 ,14 wird mittels geeigneter Raddrehzahlsensoren und deren Signalauswertung im Steuergerät34 sicher erkannt. Das Einlassventil17 wird – wie eingangs erwähnt – jeweils über das Steuergerät34 elektromagnetisch geschlossen, um einen weiterer Druckaufbau im hydraulisch beaufschlagten Vorderrad- und/oder Hinterradbremskreis2 ,4 zu unterbinden. - 2. Sollte zur Reduzierung der Blockierneigung zusätzlich ein
weiterer Druckabbau im Vorderrad- bzw. Hinterradbremskreis
2 ,4 erforderlich sein, so wird dies durch das Öffnen des mit dem Niederdruckspeicher1 verbindbaren, normalerweise stromlos geschlossenen Auslassventil18 in jedem Bremskreis erreicht. Das Auslassventil18 wird wieder geschlossen, sobald die Radbeschleunigung wieder über ein bestimmtes Maß hinaus anwächst. In der Druckabbauphase bleibt das Einlassventil17 geschlossen, so dass sich der vom Handbremshebel bzw. dem Bremspedal erzeugte Hauptzylinderdruck nicht auf den Vorderrad- bzw. Hinterradbremskreis2 ,4 fortpflanzen kann. - 3. Wenn die ermittelten Schlupfwerte wieder einen Druckaufbau
in dem jeweils hydraulisch betätigten
Bremskreis
2 ,4 erlauben, wird das Einlassventil17 entsprechend der Anforderung eines im Steuergerät34 integrierten Schlupfreglers zeitlich begrenzt geöffnet. Das für den Druckaufbau erforderliche Bremsflüssigkeitsvolumen wird vom Druckraum des jeweils manuell betätigten Hauptbremszylinders3 ,7 entnommen. Hierbei verändert sich je nach entnommenem Volumen der Arbeitskolbenhub, d.h. der jeweils manuell betätigte Hauptbremszylinder3 ,7 ersetzt in den Druckaufbauphasen eine Förderpumpe zur Druckversorgung für den daran angeschlossenen Bremskreis2 ,4 .
- 1. A blocking tendency of one of the two wheel brakes
5 .14 is determined by means of suitable wheel speed sensors and their signal evaluation in the control unit34 safely recognized. The inlet valve17 is - as mentioned above - in each case via the control unit34 Electromagnetically closed to a further pressure build-up in the hydraulically acted front and / or rear wheel brake2 .4 to prevent. - 2. Should reduce the blocking tendency additionally further pressure reduction in the front and rear brake circuit
2 .4 To be necessary, this is done by opening the with the low pressure accumulator1 connectable normally normally closed exhaust valve18 reached in each brake circuit. The outlet valve18 is closed again as soon as the wheel acceleration increases again beyond a certain level. In the pressure reduction phase, the inlet valve remains17 closed, so that the master cylinder pressure generated by the hand brake lever or the brake pedal is not on the front wheel or rear wheel brake2 .4 can reproduce. - 3. If the determined slip values again a pressure build-up in the respective hydraulically actuated brake circuit
2 .4 allow, the inlet valve17 according to the requirement of an im control unit34 integrated slip control open for a limited time. The brake fluid volume required for the pressure buildup is from the pressure chamber of the respective manually operated master cylinder3 .7 taken. In this case, depending on the volume removed, the working piston stroke, ie the respectively manually actuated master cylinder, varies3 .7 replaced in the pressure build-up phases a feed pump for pressure supply for the connected brake circuit2 .4 ,

Das in den Arbeitskammern vorhandene Reservevolumen ist in der Regel derart gewählt, dass ein voller Druckaufbau bzw. die für Krafträder gesetzlich vorgeschriebene Mindestverzögerung des Bremssystems gewährleistet ist.The in the working chambers existing reserve volume is usually chosen so that a full pressure build-up or the legally prescribed for motorcycles minimum delay of the brake system is.
