Abstract
Description
Die Erfindung betrifft eine Bremsbetätigungsvorrichtung für Kraftfahrzeuge nach dem Oberbegriff des Patentanspruches 1.The invention relates to a brake actuation device for motor vehicles according to the preamble of claim 1.
Stand der TechnikState of the art
Aus der
Aufgabe der ErfindungObject of the invention
Aufgabe der Erfindung ist es daher, eine Bremsbetätigungsvorrichtung der eingangs genannten Art zu schaffen, die unter Beibehaltung der Vorteile bezüglich des baulichen Aufwands weniger aufwendig ist.The object of the invention is therefore to provide a brake actuator of the type mentioned, which is less expensive while retaining the advantages in terms of structural complexity.
Lösung der AufgabeSolution of the task
Die Aufgabe der Erfindung wird mit den Merkmalen des Patentanspruches 1 gelöst.The object of the invention is achieved with the features of claim 1.
Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen enthalten.Advantageous embodiments of the invention are contained in the subclaims.
Mit der erfindungemäßen Lösung und ihren Ausgestaltungen wird auf überraschend einfache Weise ein Bremsbetätigungsystem für Kraftfahrzeuge geschaffen, das die Vorteile der eingangs beschriebenen Betätigungsvorrichtung aufweist, darüber hinaus noch weiter baulich vereinfacht ist und insbesondere mit weniger Ventilen auskommt. Dabei erfolgt die Druckmodulation in vorteilhafter Weise im Multiplexbetrieb, insbesondere mittels Plunger im geschlossenen Bremskreis.With the erfindungemäßen solution and its embodiments, a brake actuation system for motor vehicles is provided in a surprisingly simple manner, which has the advantages of the actuating device described above, in addition, even more structurally simplified and in particular manages with fewer valves. The pressure modulation is advantageously carried out in multiplex mode, in particular by means of plungers in the closed brake circuit.
Auch ergeben sich eine verbesserte Dynamik und regelungstechnische Vorteile durch vergrößerte Ventilquerschnitte bzw. durch genaue Drucksteuerung mittels Volumenzumessung über den Kolbenweg und Auswertung der Druck-Volumen-Kennlinie.Also, improved dynamics and control engineering advantages result from enlarged valve cross-sections or from accurate pressure control by means of volumetric metering via the piston travel and evaluation of the pressure-volume characteristic curve.
Zweckmäßig wird der von der Betätigungseinrichtung betätigte (DK) Kolben zur Steuerung eines Wegsimulators verwendet. Dieser kann vorteihaft im selben Gehäuse wie die erste Kolben-Zylinder-Einrichtung vorgesehen bzw. in diese integriert sein.Suitably, the actuated by the actuator (DK) piston is used to control a travel simulator. This can vorteihaft provided in the same housing as the first piston-cylinder device or be integrated into this.
Ferner wird mit der erfindungsgemäßen Lösung bzw. ihren Ausgestaltungen die Fehlersicherheit des Systems verbessert. Es kann eine Diagnose der Schaltfunktion und der Dichtheit aller Magnetventile vorgenommen werden. Es kann auch ein Ausfall des Bremskreises durch Druckmodulation im geschlossenen Bremskreis erkannt werden. Bei einem Ausfall schließt das Ventil zum Radzylinder oder das Sicherheitsventil des ausgefallenen Bremskreises zum Plunger. Damit bleibt eine höhere Bremswirkung erhalten. Für den Extremfall einer inneren Undichtheit ist optional ein zweites 2/2-Wege-Magnetventil in einem Bremskreis vorgesehen. Dadurch ist bei Ausfall der Bremskraftverstärkung (Plunger) im zweiten Bremskreis Bremswirkung vorhanden, auch wenn eines der Sicherheitsventile ausfällt. Die Bremskraftwirkung bleibt voll intakt für den ersten Bremskreis. Ohne diese Ventile würde sich bei Ausfall der Bremskraftverstärkung d. h. des Plungers und undichtem Sicherheitsventil der Bremskreis in den Plunger entleeren, da die Spindel ohne Selbsthemmung durch die Druckkraft bewegt und der Kolben in seine Ausgangsstellung gelangen würde.Furthermore, the fault tolerance of the system is improved with the solution according to the invention or its embodiments. It can be made a diagnosis of the switching function and the tightness of all solenoid valves. It can also be a failure of the brake circuit detected by pressure modulation in the closed brake circuit. In the event of a failure, the valve closes to the wheel cylinder or the safety valve of the failed brake circuit to the plunger. This gives a higher braking effect. For the extreme case of internal leakage, a second 2/2-way solenoid valve is optionally provided in a brake circuit. As a result, in case of failure of the brake booster (plunger) in the second brake circuit braking effect exists, even if one of the safety valves fails. The braking force remains fully intact for the first brake circuit. Without these valves would d in case of failure of the brake booster. H. of the plunger and leaking safety valve to empty the brake circuit in the plunger, as the spindle would move without self-locking by the pressure force and the piston would reach its original position.
Vorteilhaft ist in einer Leitung zum Ausgleichsbehälter ein Ein-/Auslaßventil (EA) vorgesehen, über das im Bedarfsfall Hydraulikflüssigkeit aus dem Vorratsbehälter gezielt nachgefördert werden kann. Auch verfügt das System über eine hydraulische Rückfallebene, die es ermöglicht, das Fahrzeug auch bei Ausfall des Bremskraftverstärkers noch sicher abzubremsen. Vorteilhaft erfolgt eine Auswertung der Motorstromstärke für die Bestimmung der Druck-Volumen-Kennlinie (anstelle eines Druckgebers) und eines Ausfalls der Bremskraftverstärkung. Auch kann vorteilhaft die Steigung des Gewindes der Spindel mit Selbsthemmung oder Rasteinrichtung am Rotor bzw. der Spindel des Plungers versehen sein. Damit wird bei Ausfall eines Sicherheitsventils und des Plungers kein zusätzliches Volumen durch den Plunger verdrängt. Ferner kann, insbesondere alternativ zum Druckgeber, vorteilhaft eine elastische Einrichtung bzw. ein elastisches Glied zwischen Bremspedal und dem Kolben (DK-Kolben) vorgesehen sein, wodurch die Fehlersicherheit erhöht werden kann, wie dies in weiteren Einzelheiten in der deutschen Patentanmeldung
Bei der schnellen Druckmodulation entsteht im Plunger insbesondere bei kleinen Drucken ein Unterdruck, was zur Öffnung des Saugventils führen kann. Hierzu kann durch das Druckgebersignal der Druck entsprechend gesteuert werden. Bei Ersatz des relativ teuren Druckgebers durch eine Messung des Motorstromes ist zur Vermeidung des Unterdruckes ein elektromagnetisches Absperrventil in der Rücklaufleitung vorgesehen, welches auch das Saugventil ersetzt. Ein weiterer Vorteil besteht darin, dass dieses Absperrventil diagnostizierbar ist, weil es zur Diagnose geschaltet werden kann.In the case of rapid pressure modulation, a negative pressure is created in the plunger, especially at low pressures, which can lead to the opening of the suction valve. For this purpose, the pressure can be controlled accordingly by the pressure transducer signal. When replacing the relatively expensive pressure transducer by measuring the motor current, an electromagnetic shut-off valve is provided in the return line to avoid the negative pressure, which also replaces the suction valve. Another advantage is that this shut-off valve can be diagnosed because it can be switched to the diagnosis.
