Description
Die Erfindung betrifft eine Bremseinrichtung für Fahrzeuge, vorzugsweise für Kraftfahrzeuge, nach dem Oberbegriff des Anspruches 1.The The invention relates to a braking device for vehicles, preferably for motor vehicles the preamble of claim 1.
Bekannte Bremseinrichtungen haben Hydraulikleitungen für Bremsflüssigkeit, die beim Betätigen des Bremspedales unter Druck gesetzt wird. Für die Bremsleitungen sind Ventile sowie ein Bremskraftverstärker erforderlich. Ist das Fahrzeug ein elektro- oder dieselbetriebenes Fahrzeug, ist auch noch eine Unterdruckpumpe erforderlich. Eine solche Bremseinrichtung ist konstruktiv aufwendig ausgebildet, teuer in der Herstellung und in der Montage. Aufgrund der Vielzahl von Einzelkomponenten ergibt sich ein erhöhtes Ausfallrisiko.Known Brake devices have hydraulic lines for brake fluid, which when operating the Brake pedal is pressurized. For the brake lines are valves as well as a brake booster required. Is the vehicle an electric or diesel powered Vehicle, also a vacuum pump is required. A Such braking device is structurally complex, expensive in production and in assembly. Due to the multitude of Single components results in an increased risk of default.

Der Erfindung liegt die Aufgabe zugrunde, die gattungsgemäße Bremseinrichtung so auszubilden, daß sie nur aus einer geringen Zahl von Einzelteilen besteht und dadurch kostengünstig hergestellt und in die Fahrzeuge eingebaut werden kann.Of the Invention is based on the object, the generic brake device to train them consists only of a small number of individual parts and thereby economical manufactured and installed in the vehicles.
Diese Aufgabe wird bei der gattungsgemäßen Bremseinrichtung erfindungsgemäß mit den kennzeichnenden Merkmalen des Anspruches 1 gelöst.These Task is in the generic brake device according to the invention with the characterizing Characteristics of claim 1 solved.
Bei der erfindungsgemäßen Bremseinrichtung entfallen Bremsleitungen mit Hydraulikmedium. Für das Piezoelement sowie den Piezotransformator sind lediglich elektrische Leitungen erforderlich, die einfach und kostengünstig im Fahrzeug verlegt werden können. Wird das Bremspedal gedrückt, wird das Piezoelement unter Druck gesetzt, wodurch es eine Spannung abgibt. Sie wird dem Piezotranslator des Radbremszylinders zugeführt. Aufgrund der zugeführten Ansteuerspannung dehnt sich der Piezotranslator entsprechend der angelegten Höhe der Ansteuerspannung aus, wodurch die Bremsbacken an die Bremsscheibe des jeweiligen Rades des Fahrzeuges angelegt werden. Die erfindungsgemäße Bremseinrichtung bildet ein "Break-by-wire"-System, das gänzlich ohne Bremsflüssigkeit und entsprechende Bremsflüssigkeitsleitungen auskommt. Dadurch ist eine entsprechende Hydraulik nicht erforderlich. Ebenso kann ein Bremskraftverstärker entfallen. Die piezoelektrischen Einrichtungen unterliegen nahezu keinem Verschleiß, so daß das Ausfallrisiko der erfindungsgemäßen Bremseinrichtung sehr niedrig ist.at the braking device according to the invention eliminates brake lines with hydraulic fluid. For the piezo element as well as the Piezotransformator only electrical lines are required, the easy and inexpensive can be laid in the vehicle. If the brake pedal is pressed, the piezo element is pressurized, causing it a voltage emits. It is fed to the piezotranslator of the wheel brake cylinder. by virtue of the supplied Drive voltage, the piezotranslator expands according to the applied height the drive voltage, causing the brake shoes to the brake disc be created of the respective wheel of the vehicle. The braking device according to the invention forms a "break-by-wire" system, completely without brake fluid and corresponding brake fluid lines gets along. As a result, a corresponding hydraulic is not required. Likewise, a brake booster omitted. The piezoelectric devices are almost subject no wear, so that Risk of failure of the braking device according to the invention is very low.
