Description
Die Erfindung betrifft ein Lenkrad für ein Kraftfahrzeug der im Oberbegriff des Patentanspruchs 1 angegebenen Art.The The invention relates to a steering wheel for a motor vehicle specified in the preamble of claim 1. Art.
Ein
derartiges Lenkrad ist beispielsweise bereits aus der
Aufgabe der vorliegenden Erfindung ist es, ein schwingungsgedämpftes Lenkrad der eingangs genannten Art zu schaffen, welches einfacher und kostengünstiger herstellbar ist.task The present invention is a vibration-damped To create steering wheel of the type mentioned, which is easier and is cheaper to produce.
Die Aufgabe wird erfindungsgemäß durch ein Lenkrad für ein Kraftfahrzeug mit den Merkmalen des Patentanspruchs 1 gelöst. Vorteilhafte Ausgestaltungen mit zweckmäßigen und nicht-trivialen Weiterbildungen der Erfindung sind in den übrigen Patentansprüchen angegeben.The Task is inventively by a steering wheel for a motor vehicle with the features of the claim 1 solved. Advantageous embodiments with appropriate and non-trivial developments of the invention are in the others Claims specified.
Ein Lenkrad für ein Kraftfahrzeug, welches einfacher und kostengünstiger herstellbar ist, ist erfindungsgemäß dadurch geschaffen, dass die Schwingungsdämpfungseinrichtung wenigstens ein Piezoelement umfasst, mittels welchem eine mechanische Energie der Schwingung in elektrische Energie umwandelbar ist. Im Gegensatz zu aus dem Stand der Technik bekannten Schwingungsdämpfungseinrichtungen sind somit keine aufwendigen und teuren Maßnahmen zur Abdichtung der Schwingungsdämpfungseinrichtung gegen ein Auslaufen von als Dämpfungsmaterial verwendeten Flüssigkeiten erforderlich. Das erfindungsgemäße Lenkrad ermöglicht somit auf konstruktiv einfache und kostengünstige Weise über die Umwandlung der mechanischen Energie der Schwingung in elektrische Energie eine signifikante Reduzierung der Schwingungsamplituden. Da bei einem Lenkrad spürbare Schwingungen besonders auffällig sind, wird dadurch der Komfort für den Fahrer erheblich verbessert und zudem die Wertanmutung des Kraftfahrzeuges deutlich erhöht.One Steering wheel for a motor vehicle, which is simpler and less expensive can be produced is inventively created by in that the vibration damping device has at least one piezoelectric element includes, by means of which a mechanical energy of the vibration is convertible into electrical energy. Unlike from the state known in the art vibration damping devices are therefore no expensive and expensive measures for sealing the vibration damping device against leakage of fluids used as damping material required. The steering wheel according to the invention allows thus in a structurally simple and inexpensive way over the conversion of the mechanical energy of the vibration into electrical Energy a significant reduction in vibration amplitudes. As with a steering wheel noticeable vibrations particularly noticeable Thus, the comfort for the driver becomes considerable improves and also significantly increases the perceived value of the motor vehicle.
