Description
Die vorliegende Erfindung betrifft einen Stoßdämpfer. Die vorliegende Erfindung betrifft darüber hinaus entsprechende Verfahren zur Stoßdämpfung sowie zur Herstellung eines Stoßdämpfers. The present invention relates to a shock absorber. The present invention also relates to corresponding methods for shock absorption and for producing a shock absorber.
Stand der Technik State of the art
In der Fahrwerkstechnik wird jedwedes Bauteil zur Dämpfung mechanischer Schwingungen, Vibrationen, Erschütterungen oder Stöße als Schwingungs- oder Stoßdämpfer bezeichnet. Bekannt sind neben Achsdämpfern insbesondere Feder-Dämpfer-Einheiten, bei welchen Feder und Stoßdämpfer in ein Bauteil integriert sind, sowie sogenannte MacPherson-Federbeine, die das gedämpfte Rad zusätzlich in Längs- und Querrichtung führen. Handelsübliche Personenkraftwagen werden gleichwohl überwiegend mit hydraulischen Stoßdämpfern in Ein- oder Zweirohrbauweise ausgerüstet. Vereinzelt eingesetzt werden magnetorheologische Stoßdämpfer, die anstelle herkömmlichen Hydrauliköls mit einer Suspension magnetisch polarisierbarer Partikel betrieben werden, um die erforderliche Dämpfung abhängig von Fahrzustand und Straßenbeschaffenheit elektromagnetisch anzupassen. In chassis technology, any component for damping mechanical vibrations, vibrations, vibrations or shocks is referred to as a vibration or shock absorber. In addition to axle dampers are known in particular spring-damper units, in which spring and shock absorbers are integrated into one component, and so-called MacPherson struts, which additionally guide the damped wheel in the longitudinal and transverse directions. Commercially available passenger cars are nevertheless predominantly equipped with hydraulic shock absorbers in single or twin-pipe design. Magnetorheological shock absorbers, which are operated instead of conventional hydraulic oil with a suspension of magnetically polarisable particles, are used occasionally in order to electromagnetically adapt the required damping depending on driving conditions and road conditions.
Offenbarung der Erfindung Disclosure of the invention
Die Erfindung stellt einen Stoßdämpfer, ein entsprechendes Verfahren zur Stoßdämpfung und ein Herstellungsverfahren für einen erfindungsgemäßen Stoßdämpfer gemäß den unabhängigen Ansprüchen bereit. The invention provides a shock absorber, a corresponding method for shock absorption and a manufacturing method for a shock absorber according to the invention according to the independent claims.
Der konventionelle Dämpfer soll demnach etwa bei – insbesondere geländegängigen – Elektrofahrzeugen durch einen elektromagnetischen Dämpfer in der Funktion eines Lineargenerators ersetzt werden. Durch die Vertikalbewegung jedes Rades wird so eine Spannung in den Stator induziert, wodurch beispielsweise ein als Traktionsbatterie nutzbarer elektrischer Speicher geladen wird. Accordingly, the conventional damper is to be replaced by an electromagnetic damper in the function of a linear generator, for example in electric vehicles, in particular all-terrain vehicles. As a result of the vertical movement of each wheel, a voltage is induced in the stator, as a result of which, for example, an electric store which can be used as a traction battery is charged.
Ein Landfahrzeug kann nach diesem Wirkprinzip – selbst bei der Fahrt auf Straßen mit normaler Oberflächenbeschaffenheit – eine elektrische Leistung von bis zu 100 W abgeben, wodurch sich eine Kraftstoffeinsparung von ca. 0,1 l/100 km realisieren lässt. Jedoch wird bei der Fahrt durch ein Gelände oder auf einer unebenen Landstraße unter Umständen bedeutend mehr Energie zurückgewonnen, sodass sich der Einbau eines erfindungsgemäßen Stoßdämpfers oder Federbeins auch unter wirtschaftlichen Gesichtspunkten durchaus rentieren mag. A land vehicle can emit an electric power of up to 100 W, even when driving on roads with a normal surface finish, which results in a fuel saving of approx. 0.1 l / 100 km. However, significantly more energy may be recovered when driving through a terrain or on a rough country road, so that the installation of a shock absorber or shock absorber according to the invention may also be profitable from an economic point of view.
Weiterhin kann durch eine variable Stromaufnahme die Dämpfung innerhalb von Millisekunden variiert werden, wodurch die Fahrdynamik verbessert werden kann. Alternativ kann die Funktion auch umgekehrt werden, sodass gleichsam ein aktives Fahrwerk entsteht, welches eine Wank- und Nickabstützung ermöglicht. Furthermore, the damping can be varied within milliseconds by a variable current consumption, whereby the driving dynamics can be improved. Alternatively, the function can also be reversed, so that as it were an active suspension is created, which allows a roll and pitch support.
Weitere vorteilhafte Ausgestaltungen der Erfindung sind in den abhängigen Patentansprüchen angegeben. Further advantageous embodiments of the invention are specified in the dependent claims.
