Abstract

The hydraulic brake installation has a pedal-operated main cylinder connected to at least one pressure chamber of a brake circuit with at least one wheel brake fitted to a driven wheel. The pressure medium flows from the pressure medium tank into a pressure-compensated run-out chamber in the main brake cylinder which, via a pedal path-dependent closing connection, is connected to a pressure chamber of the main brake cylinder. A self-priming pump for the purpose of a drive slip regulation draws pressure medium through the main brake cylinder out of the pressure medium tank and delivers it into the wheel brake of the driven wheel. The suction side of the pump (52) is connected to one of the run-out chambers (6) of the main brake cylinder (1). ADVANTAGE - No additional pump suction connection to pressure medium tank necessary.

Description

Die Erfindung geht von einer hydraulischen Bremsanlage gemäß dem Oberbegriff des Hauptanspruches aus.The invention is based on a hydraulic brake system according to the preamble of the main claim.

Eine gattungsgemäße Bremsanlage ist aus der DE 41 00 389 A1 bekannt. Diese Bremsanlage arbeitet während einer Bremsschlupfregelung nach dem Rückförderprinzip. Zur Antriebsschlupfregelung besitzt die Saugseite der selbstansaugenden Pumpe eine Saugleitung, die mit einem hydraulischen Schaltventil versehen ist und an die Bremsleitung anschließt. Über diese Saugleitung, die Bremsleitung, die Druckkammer des Hauptzylinders, das Zentralventil und den Anschluß des Hauptzylinders am Druckmittelbehälter saugt die Pumpe Druckmittel an und fördert es in diejenige Radbremse, bei welcher übermäßiger Antriebsschlupf festgestellt wird. Dabei ist es von Vorteil, daß am Druckmittelbehälter kein zusätzlicher Sauganschluß für die Pumpe angebracht werden muß und daß die zur Bremsschlupfregelung verwendete Pumpe selbstansaugend ausgelegt ist, so daß sie zugleich für die Antriebsschlupfregelung eingesetzt werden kann.A generic brake system is from DE 41 00 389 A1 known. This brake system works during one Brake slip control according to the return feed principle. For Traction control system has the suction side of the self-priming pump with a suction line hydraulic switching valve is provided and to the Brake line connects. Via this suction line, the Brake line, the pressure chamber of the master cylinder, the Central valve and the connection of the master cylinder on The pump sucks pressure medium tank and promotes it in the wheel brake which is excessive Traction slip is determined. It is from Advantage that no additional on the pressure medium container Suction port for the pump must be attached and that the pump used for brake slip control is designed to be self-priming, so that it can also be used for Traction control system can be used.

Es haben sich jedoch zwei Nachteile herausgestellt. However, two drawbacks have emerged.  

Zum einen ergeben sich durch die Ansaugung über die Zentralventile hohe Drosselverluste bei der Pumpenleistung. Zum anderen ist für jeden Bremskreis, der zur Antriebsschlupfregelung ausgerüstet ist, ein Schaltventil erforderlich, welches die Saugleitung bei jeder pedalbetätigten Bremsung sperrt.On the one hand, suction results from the Central valves high throttle losses at the Pump output. On the other hand, for each brake circuit, the is equipped for traction control, a Switching valve required, which the suction line at every pedal-operated braking locks.

Die Aufgabe der vorliegenden Erfindung liegt darin, eine gattungsgemäße Bremsanlage zu schaffen, bei welcher kein zusätzlicher Pumpensauganschluß am Druckmittelbehälter erforderlich ist, bei welcher jedoch die Pumpenförderleitstung verbessert wird. Zusätzlich soll die Bremsanlage preiswert herstellbar sein.The object of the present invention is a Generic brake system to create, in which no Additional pump suction connection on the pressure medium tank is required, but with which Pump delivery line is improved. In addition, should the brake system can be manufactured inexpensively.

Diese Aufgabe wird erfindungsgemäß gelöst durch die Merkmale des kennzeichnenden Teils im Hauptanspruch.This object is achieved by the Features of the characterizing part in the main claim.

Das Prinzip der Erfindung besteht darin, die Saugseite der Pumpe an die ständig mit dem Druckmittelbehälter in Verbindung stehenden Nachlaufkammer des Hauptbremszylinders anzuschließen. Das ermöglicht ein Ansaugen direkt aus den Druckmittelbehälter ohne einen Umweg über die Zentralventile. Außerdem erübrigt sich der Einbau eines Schaltventils in der Saugleitung, weil bei einer pedalbetätigten Bremsung die drucklosen Nachlaufkammern durch das Zentralventil von den Druckkammern des Hauptbremszylinders abgetrennt sind.The principle of the invention is the suction side the pump to the constantly with the pressure medium tank in Connected trailing chamber of the To connect the master brake cylinder. That enables one Suck directly from the pressure medium container without one Detour via the central valves. In addition, the Installation of a switching valve in the suction line, because at a pedal-operated braking the depressurized Follow-up chambers through the central valve from the Pressure chambers of the master brake cylinder are separated.

Bei Bremsanlagen, welche alle angetriebenen Räder mit einem einzigen Bremskreis versorgen, ist nur ein solcher Sauganschluß erforderlich. In brake systems, which all driven wheels with supplying a single brake circuit is only one Suction connection required.  

Weitere vorteilhafte Merkmale ergeben sich aus der folgenden Beschreibung eines bevorzugten Ausführungsbeispiels anhand einer Zeichnung.Further advantageous features result from the following description of a preferred Embodiment with reference to a drawing.

Die einzige Figur zeigt eine erfindungsgemäße Bremsanlage mit einem Tandemhauptbremszylinder, wobei nur einer der beiden Bremskreise dargestellt ist.The single figure shows a brake system according to the invention with a tandem master brake cylinder, with only one of the two brake circuits is shown.

Da die abgebildete Bremsanlage eine diagonale Bremskreisaufteilung besitzt, ist der nicht dargestellte Sekundärbremskreis genauso aufgebaut wie der dargestellte Primärbremskreis. Dabei wurden alle elektronischen Schaltelemente, wie Sensoren und elektronische Kontrolleinheit, der besseren Übersichtlichkeit wegen weggelassen.Since the braking system shown is a diagonal Has brake circuit division, is not shown Secondary brake circuit constructed exactly like the one shown Primary brake circuit. All were electronic Switching elements, such as sensors and electronic Control unit, for better clarity omitted.

Der Hauptbremszylinder 1 besitzt zwei Behälteranschlüsse 2 und 4 zu jeweils einer Kammer eines nicht dargestellten Druckmittelbehälters. Dabei ist der Behälteranschluß 2 dem Primärbremskreis zugeordnet und mündet entsprechend in die Nachlaufkammer 6. Der Behälteranschluß 4 ist mit der Nachlaufkammer 8 des Sekundärbremskreises verbunden. Von jeder der Nachlaufkammern 6 und 8 führt jeweils ein Sauganschluß 10 bzw. 12 zur Saugseite einer selbstansaugenden Pumpe. Diese Sauganschlüsse 10 und 12 sind jeweils so in der Hauptzylinderbohrung 14 angebracht, daß sie von keiner der Manschettendichtungen 16, 18, 20 und 22 überfahren werden. Die Bremsleitung 24 des Primärbremskreises sowie die nicht dargestellte Bremsleitung des Sekundärbremskreises sind mit den Druckkammern 26 bzw. 28 auf bekannte Weise verbunden. The master brake cylinder 1 has two container connections 2 and 4 , each to a chamber of a pressure medium container, not shown. Here, the container connection 2 is assigned to the primary brake circuit and opens out accordingly into the trailing chamber 6 . The container connection 4 is connected to the trailing chamber 8 of the secondary brake circuit. From each of the trailing chambers 6 and 8 , a suction connection 10 or 12 leads to the suction side of a self-priming pump. These suction ports 10 and 12 are each mounted in the master cylinder bore 14 so that they are not run over by any of the sleeve seals 16 , 18 , 20 and 22 . The brake line 24 of the primary brake circuit and the brake line of the secondary brake circuit, not shown, are connected to the pressure chambers 26 and 28 in a known manner.

Die dargestellte Grundstellung des druckstangenbetätigten Primärkolbens 30 sowie des Sekundärkolbens 32 ist durch die Kraft von Druckfedern bestimmt, wobei der Primärkolben 30 am Anschlagbolzen 34 anliegt, während der Sekundärkolben 32 gegen den Anschlagbolzen 36 gedrückt wird. Dabei liegen die Stößel der Zentralventile 38 und 40 jeweils an den zugeordneten Anschlagbolzen 34 bzw. 36 an, so daß in der Grundstellung die Zentralventile offengehalten werden. Bei einer Pedalbremsung werden die Kolben 30 und 32 zur linken Bildseite verschoben, so daß die Zentralventile 38 und 40 sich schließen können. Die Nachlaufkammern 6 und 8 sind von den zugehörigen Druckkammern 26 und 28 getrennt.The basic position shown of the push rod-actuated primary piston 30 and of the secondary piston 32 is determined by the force of compression springs, the primary piston 30 abutting the stop pin 34 , while the secondary piston 32 is pressed against the stop pin 36 . The plungers of the central valves 38 and 40 each abut the associated stop bolts 34 and 36 , respectively, so that the central valves are kept open in the basic position. When the pedals are braked, the pistons 30 and 32 are shifted to the left side of the figure, so that the central valves 38 and 40 can close. The trailing chambers 6 and 8 are separated from the associated pressure chambers 26 and 28 .

Der dargestellte Primärbremskreis ist folgendermaßen aufgebaut:The primary brake circuit shown is as follows built up:

Die Bremsleitung 24 führt von der Druckkammer 26 über das Einlaßventil 42 zur Radbremse 46 eines nicht angetriebenen Rades so wie über das Trennventil 50 und das Einlaßventil 44 zur Radbremse 48 eines angetriebenen Rades. Die Pumpe 52 saugt im Fall einer Bremsschlupfregelung aus dem Niederdruckspeicher 56 und zu Beginn einer Antriebsschlupfregelung aus der Nachlaufkammer 6 über Rückschlagventil 54 Druckmittel an und fördert es über die Druckleitung 70 mit dem Rückschlagventil 58 in die Bremsleitung 24 zwischen Trennventil 50 und Einlaßventil 44 der Radbremse 48 des angetriebenen Rades. Der Niederdruckspeicher 56 wird dadurch gefüllt, daß bei einer Schlupfregelung die Auslaßventile 60 und 62 öffnen und Druckmittel über die Rücklaufleitung 64 ablassen. Das Vordruckventil 66, über welches der Niederdruckspeicher 56 gefüllt wird, hat einen Vordruck, der etwa dem Atmosphärendruck entspricht und verhindert, das bei einer Antriebschlupfregelung in den Radbremsen 46 und 48 Unterdruck auftritt. Der Niederdruckspeicher 56 ist außerdem wie schon beschrieben mit der Saugseite der Pumpe 52 verbunden und außerdem über das Vordruckventil 68 an die Druckseite der Pumpe 52 angeschlossen. Dieses Vordruckventil 68 hat ebenfalls einen Vordruck, der etwa dem Atmosphärendruck entspricht und begrenzt zusammen mit dem Rückschlagventil 58 nach Beendigung einer Schlupfregelung den in Niederdruckspeicher 56 verbleibenden Restdruck. Der Druck des Niederdruckspeichers 56 wird dann über das Vordruckventil 68, das Rückschlagventil 58, das geöffnete Trennventil 50 und die Bremsleitung 24 durch den Hauptbremszylinder 1 hindurch abgebaut.The brake line 24 leads from the pressure chamber 26 via the inlet valve 42 to the wheel brake 46 of a non-driven wheel as well as via the isolating valve 50 and the inlet valve 44 to the wheel brake 48 of a driven wheel. In the event of a brake slip control from the low-pressure accumulator 56 and at the beginning of a traction control from the overflow chamber 6, the pump 52 draws in pressure medium via a check valve 54 and conveys it via the pressure line 70 with the check valve 58 into the brake line 24 between the isolating valve 50 and the inlet valve 44 of the wheel brake 48 of the driven wheel. The low-pressure accumulator 56 is filled in that, in the event of a slip control, the outlet valves 60 and 62 open and discharge pressure medium via the return line 64 . The admission pressure valve 66 , via which the low-pressure accumulator 56 is filled, has an admission pressure which corresponds approximately to the atmospheric pressure and prevents a negative pressure which occurs in the wheel brakes 46 and 48 when the traction control system is in operation. The low-pressure accumulator 56 is also as already described connected to the suction side of the pump 52 and also connected to the pressure side of the pump 52 via the valve inlet pressure 68th This admission pressure valve 68 also has an admission pressure which corresponds approximately to the atmospheric pressure and, together with the check valve 58, limits the residual pressure remaining in the low pressure accumulator 56 after a slip control has ended. The pressure of the low-pressure accumulator 56 is then reduced via the pre-pressure valve 68 , the check valve 58 , the opened isolation valve 50 and the brake line 24 through the master brake cylinder 1 .

Bei jeder pedalbetätigten Bremsung, also auch bei einer Bremsschlupfregelung, bleibt das Trennventil 50 geöffnet. Bei einer Antriebsschlupfregelung wird das Trennventil 50 geschlossen, so daß von der Pumpe 52 dann nur die Radbremse 48 des angetriebenen Rades gefüllt wird. Zur Begrenzung von Regelgeräuschen ist dem Trennventil 50 das Überdruckventil 72 parallelgeschaltet, welches bei einem Druck öffnet, der zur Antriebsschlupregelung ausreichend ist. Da am Einlaßventil 44 dann nicht mehr der volle Pumpendruck steht, werden die Schaltgeräusche geringer. Außerdem ist dem Trennventil 50 das Rückschlagventil 74 parallelgeschaltet, welches dafür sorgt, daß auch während einer Antriebsschlupfregelung, wenn das Trennventil 50 geschlossen ist, in die Radbremse 48 eingebremst werden kann. Die Radbremse 46 ist von der Antriebsschlupfregelung unberührt und kann ebenfalls jederzeit betätigt werden.The isolating valve 50 remains open with each pedal-operated braking, that is to say also with a brake slip control. In the case of traction control, the isolating valve 50 is closed, so that only the wheel brake 48 of the driven wheel is then filled by the pump 52 . To limit control noises, the isolation valve 50 is connected in parallel with the pressure relief valve 72 , which opens at a pressure which is sufficient for traction control. Since the full pump pressure is then no longer at the inlet valve 44 , the switching noise is reduced. In addition, the check valve 74 is connected in parallel with the isolating valve 50 , which ensures that even during a traction control, when the isolating valve 50 is closed, the wheel brake 48 can be braked. The wheel brake 46 is unaffected by the traction control system and can also be actuated at any time.

Zwar ist in dieser Figur ein Hauptbremszylinder mit Zentralventilen dargestellt, jedoch ist die Erfindung nicht auf solche Hauptbremszylinder begrenzt. Vielmehr kann sie auch analog auf solche Hauptbremszylinder angewendet werden, welche beispielsweise mit von Manschettendichtungen überfahrenen Nachlaufbohrungen zu den Druckkammern versehen sind.A master brake cylinder is included in this figure Central valves shown, however, is the invention not limited to such master brake cylinders. Much more it can also be analogous to such master brake cylinders are used, for example with von Cuff seals traversed overrun bores the pressure chambers are provided.
