Abstract
Description
Die Erfindung betrifft eine hydraulische Fahrzeugbremse mit Feststellbremsvorrichtung mit einem Bremsgehäuse, in dem ein hydraulischer Betriebsdruckraum von einem Bremskolben begrenzt ist, wobei die Feststellbremsvorrichtung auf den Bremskolben wirkt und im zugespannten Zustand mittels einer von einem Elektromotor angetriebenen Gewindemutter-Spindel-Anordnung verriegelbar ist.The The invention relates to a hydraulic vehicle brake with parking brake device with a brake housing, in which a hydraulic operating pressure chamber of a brake piston is limited, wherein the parking brake device on the brake piston acts and in the applied state by means of one of an electric motor driven nut-spindle arrangement is lockable.
Aus
der
Der Erfindung liegt also die Aufgabe zugrunde, eine hydraulische Fahrzeugbremse der eingangs genannten Gattung dahingehend zu verbessern, dass die Einstellung der zur Durchführung eines Feststellbremsvorganges notwendigen Zuspannkraft zuverlässig erfolgt.Of the Invention is therefore the object of a hydraulic vehicle brake to improve the type mentioned in that the Attitude of the implementation a parking brake necessary clamping force is reliable.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass ein Sensor zur direkten Erfassung der Zuspannkraft vorgesehen ist.These Task is inventively characterized solved, a sensor is provided for the direct detection of the application force is.
Eine vorteilhafte Ausführung des Erfindungsgegenstandes sieht vor, dass der Sensor durch einen Kraftsensor gebildet ist, über welchen sich die Spindel am Gehäuse des Elektromotors abstützt.A advantageous embodiment of the subject invention provides that the sensor by a force sensor is formed over which the spindle on the housing supported by the electric motor.
Bei einer anderen vorteilhaften Ausführung wird der Sensor durch einen Wegsensor gebildet, der die Bewegung der Spindel, die sich über ein Federelement am Bremsgehäuse abstützt, erfasst.at another advantageous embodiment the sensor is formed by a displacement sensor, which controls the movement of the Spindle that over a spring element on the brake housing supported, detected.

Außerdem weist die Gewindemutter an ihrem Außenumfang eine Verdrehsicherung auf, die axiale Bewegungen der Gewindemuter relativ zum Bremskolben zulässt.In addition, points the threaded nut on its outer circumference an anti-rotation, the axial movements of the threaded nut relative to the brake piston permits.
Zur Realisierung eines Feststellbremsvorganges ist zwischen der Gewindemutter und der Spindel ein selbsthemmendes Gewinde vorgesehen.to Realization of a parking brake operation is between the threaded nut and the spindle provided a self-locking thread.
Eine vorteilhafte Weiterbildung des Erfindungsgegenstands sieht vor, dass ein mit dem Bremskolben zusammenwirkender, hydraulisch ladbarer Arbeitsspeicher mit mindestens einem integrierten Federelement vorgesehen ist, wobei das Federelement derart ausgelegt ist, dass es während Betriebsbremsungen keine Komprimierung erfährt.A advantageous development of the subject invention provides that cooperating with the brake piston, hydraulically loadable Memory provided with at least one integrated spring element is, wherein the spring element is designed such that it during service braking no compression experiences.
Besonders vorteilhaft ist es dabei, wenn das Federelement derart ausgelegt ist, dass der Vergleich des Komprimierungsweges des Federelementes mit der dazu notwendigen Kraft ein Maximum aufweist.Especially It is advantageous if the spring element designed in this way is that the comparison of the compression path of the spring element with the necessary force has a maximum.
Bei einer weiteren Ausführungsform ist eine elektronische Steuereinheit zur Auswertung der Stromaufnahme des Elektromotors vorgesehen.at a further embodiment is an electronic control unit for evaluating the power consumption provided the electric motor.
Außerdem ist ein mechanisches Notlösemittel zum Lösen der Feststellbremse vorgesehen. Besonders vorteilhaft ist, dass eine Hülse vorgesehen ist, die in den Bremskolben hinein ragt und mit diesem fest verbunden ist und die Gewindemutter-Spindel-Anordnung aufnimmt.Besides that is a mechanical emergency solvent to release provided the parking brake. It is particularly advantageous that a sleeve is provided, which projects into the brake piston and with this is firmly connected and receives the threaded nut spindle assembly.
