Abstract
Die Erfindung betrifft ein Fahrwerk eines Kraftfahrzeugs mit zumindest einem die Hubbewegung des Fahrzeug-Aufbaus gegenüber einem Rad oder einer Achse des Fahrzeugs dämpfenden Rotationsdämpfer, welcher ausgelegt ist, aus der durch die Hubbewegung erzeugten und in das Fahrwerk eingebrachten Dämpfkraft elektrische Energie zu erzeugen und der als hydraulischer Dämpfer ausgebildet ist, welcher ein viskoses Fluid verlagert, welches einen Gerotor antreibt, an den eine Elektromaschine angekoppelt ist. Vorzugsweise liegt die Rotationsachse des Rotationsdämpfers, um welche sich zwei Bauelemente des Rotationsdämpfers als Folge einer Hubbewegung des Fzg.-Aufbaus gegeneinander drehen und damit einen Teil des Fluids verlagern, koaxial zur Rotationsachse des Gerotors und der Elektromaschine.The invention relates to a chassis of a motor vehicle with at least one of the lifting movement of the vehicle body relative to a wheel or an axle of the vehicle damping rotary damper, which is designed to generate from the generated by the lifting movement and introduced into the suspension damping force electrical energy and as hydraulic damper is formed, which displaces a viscous fluid, which drives a gerotor, to which an electric machine is coupled. Preferably, the axis of rotation of the rotary damper, around which two components of the rotary damper rotate as a result of a lifting movement of the vehicle body against each other and thus displace a portion of the fluid, coaxial with the axis of rotation of the gerotor and the electric machine.
Description
Die Erfindung betrifft ein Fahrwerk eines Kraftfahrzeugs mit zumindest einem die Hubbewegung des Fahrzeug-Aufbaus gegenüber einem Rad oder einer Achse des Fahrzeugs dämpfenden Rotationsdämpfer, welcher ausgelegt ist, aus der durch die Hubbewegung erzeugten und in das Fahrwerk eingebrachten Dämpfkraft elektrische Energie zu erzeugen.The invention relates to a chassis of a motor vehicle with at least one of the lifting movement of the vehicle body relative to a wheel or an axle of the vehicle damping rotary damper which is designed to generate from the generated by the lifting movement and introduced into the suspension damping force electrical energy.

Als weiterer Stand der Technik für einen im Fahrwerk eines Kraftfahrzeugs vorgesehenen und die Hubbewegung des Fahrzeug-Aufbaus gegenüber einem Rad oder einer Achse des Fahrzeugs dämpfenden Dämpfer, welcher ausgelegt ist, aus der durch die Hubbewegung erzeugten und in das Fahrwerk eingebrachten Dämpfkraft elektrische Energie zu erzeugen, sei die
Zurückkommend auf die oben erstgenannte und zur Bildung des Oberbegriffs des Patentanspruchs 1 herangezogene
Eine Abhilfemaßnahme für diese geschilderte Problematik aufzuzeigen, ist Aufgabe der vorliegenden Erfindung.To point out a remedy for this problem is the object of the present invention.
Die Lösung dieser Aufgabe ist für ein Fahrwerk nach dem Oberbegriff des Anspruchs 1 dadurch gekennzeichnet, dass der Rotationsdämpfer als hydraulischer Dämpfer ausgebildet ist, welcher ein viskoses Fluid verlagert, und dass für die elektrische Energieerzeugung ein Gerotor mit angekoppelter Elektromaschine vorgesehen ist, wobei das verlagerte Fluid den Gerotor antreibt.The solution to this problem is for a chassis according to the preamble of claim 1, characterized in that the rotary damper is designed as a hydraulic damper, which displaces a viscous fluid, and that a gerotor with coupled electric machine is provided for the electrical power generation, wherein the displaced fluid drives the gerotor.
Vorschlagen wir somit eine besonders kompakt bauende Anordnung kombiniert mit einer aufgrund der hydraulischen Dämpfung mit einem viskosen Fluid besonders guten Dämpfungscharakteristik, indem ein hydraulischer Rotationsdämpfer vorgesehenen wird, dessen durch die Hubbewegung des Fzg.-Aufbaus verdrängtes viskoses Dämpfungs-Fluid durch eine Innenzahnrad-Fluidmaschine („Gerotor”) geführt ist, an die eine Elektromaschine angekoppelt ist, d. h. von der bzw. dem eine Elektromaschine angetrieben wird.Thus, we propose a particularly compact arrangement combined with a particularly good damping characteristic due to the hydraulic damping with a viscous fluid, by providing a hydraulic rotary damper whose viscous damping fluid displaced by the lifting motion of the vehicle body is driven by an internal gear fluid machine ( "Gerotor") is guided, to which an electric machine is coupled, d. H. from which or an electric machine is driven.
Besonders raumsparend und ohne zwischengeschaltetes Getriebe kann ein erfindungsgemäßes Fahrwerk gestaltet werden, wenn eine bzw. die Rotationsachse des Rotationsdämpfers, um welche sich wie üblich zwei Bauelemente des Rotationsdämpfers als Folge einer Hubbewegung des Fzg.-Aufbaus gegeneinander drehen und damit einen Teil des besagten viskosen Fluids verlagern, koaxial zur Rotationsachse des Gerotors sowie der Elektromaschine liegt, d. h. diese drei wesentlichen Elemente Rotationsdämpfer und Gerotor und Elektromaschine besitzen eine gemeinsame Drehachse. Dabei können sogar einzelne Teile konzentrisch zueinander angeordnet werden; insbesondere kann ein Teil des Rotors des Gerotors zusammen mit dem Rotor der Elektromaschine quasi innerhalb von deren Stator liegen. Weiterhin kann vorgesehen sein, dass die Elektromaschine gesteuert antreibbar ist, so dass der Rotationsdämpfer als aktiver Dämpfer fungieren kann, womit der Fzg.-Aufbau gegenüber dem Rad oder der Achse angehoben oder abgesenkt werden kann.Particularly space-saving and without intermediate transmission, an inventive suspension can be designed when one or the rotation axis of the rotary damper, around which turn as usual two components of the rotary damper as a result of a stroke of Fzg. Construction against each other and thus a portion of said viscous fluid shift, coaxial with the axis of rotation of the gerotor and the electric machine is located, ie these three essential elements rotary damper and gerotor and electric machine have a common axis of rotation. In this case, even individual parts can be arranged concentrically with each other; In particular, a part of the rotor of the gerotor together with the rotor of the electric machine quasi lie within the stator. Furthermore, it can be provided that the electric machine can be driven in a controlled manner, so that the rotational damper can act as an active damper, with which the vehicle body can be raised or lowered relative to the wheel or the axle.
