In Figur 1 ist eine Radaufhängung gemäß der WO 2005/091699 A1 der Anmelderin, umfassend ein Feder-Dämpfer-Modul schematisch dargestellt.1 shows a suspension according to the applicant's WO 2005/091699 A1, comprising a spring-damper module shown schematically.
Hierbei weist der Achsschenkel 1 eine obere Aufnahme 2 und eine untere Aufnahme 3 auf, in welcher sich ein Achsschenkelbolzen 4 befindet, welcher koaxial zu einer Drehachse 5 angeordnet ist. Auf diese Weise kann sich der Achsschenkel 1 um die Achse 5 drehen, um Lenkbewegungen für das Fahrzeugrad 6 auszuführen.Here, the steering knuckle 1 has an upper receptacle 2 and a lower receptacle 3, in which a king pin 4 is located, which is arranged coaxially to a rotation axis 5. In this way, the steering knuckle 1 can rotate about the axis 5 to perform steering movements for the vehicle wheel 6.
Bei dem in Figur 1 gezeigten Beispiel weist der Achsschenkelbolzen 4 an seinem oberen Ende eine Lagerung 7 auf, welche beispielsweise als Rollenlagerung, Gleitlagerung, Kugelgelenk oder als Molekulargelenk ausgeführt sein kann, und über welche ein erster Arm 8 und ein zweiter Arm 9 eines oberen Querlenkers 10 verbunden sind. Des weiteren weist der Achsschenkelbolzen 4 an seinem unte- ren Ende eine Lagerung 1 1 auf, welche wie die Lagerung 7 ausgeführt sein kann und über die ein erster Arm 12 und ein zweiter Arm 13 eines unteren Querlenkers 14 verbunden sind. Indem die oberen Querlenker 10 und die unteren Querlenker 14 direkt mit dem Achsschenkelbolzen 4 verbunden sind, verlängern sich die Querlenker, was zu einer Verbesserung der Feder-Kinematik führt. Vorzugsweise sind die Lagerungen 7 und 1 1 innerhalb der Felge 15 angeordnet.In the example shown in Figure 1, the kingpin 4 at its upper end to a bearing 7, which may for example be designed as a roller bearing, plain bearing, ball joint or molecular joint, and on which a first arm 8 and a second arm 9 of an upper arm 10 are connected. Furthermore, the kingpin 4 at its lower ren end of a storage 1 1, which may be performed as the bearing 7 and via which a first arm 12 and a second arm 13 of a lower arm 14 are connected. By the upper wishbones 10 and the lower arm 14 are connected directly to the kingpin 4, the wishbone lengthen, resulting in an improvement of the spring kinematics. Preferably, the bearings 7 and 1 1 are arranged within the rim 15.
Zwischen der oberen Aufnahme 2 und der unteren Aufnahme 3 ist ein Träger 16 angeordnet, welcher mit einem Feder-Dämpfer-Modul 17 verbunden ist, so dass sich der Achsschenkel 1 über den Träger (Federträger) 16 und das Feder- Dämpfer-Modul 17 an einem nicht dargestellten Fahrzeugrahmen abstützt. Der erste Arm 8 und der zweite Arm 9 sowie der erste Arm 12 und der zweite Arm 13 sind ebenfalls an einem nicht dargestellten Fahrzeugrahmen angelenkt. Wie aus Figur 1 ersichtlich sind der erste Arm 12 und der zweite Arm 13 überkreuzt angeordnet, wodurch der mögliche Lenkwinkel erhöht werden kann. Hierbei ist das Feder- Dämpfer-Modul 17 außerhalb des Fahrzeugrahmens und oberhalb des oberen Querlenkers 10 angeordnet.Between the upper receptacle 2 and the lower receptacle 3, a carrier 16 is arranged, which is connected to a spring-damper module 17, so that the stub axle 1 via the carrier (spring carrier) 16 and the spring-damper module 17 at supported a vehicle frame, not shown. The first arm 8 and the second arm 9 and the first arm 12 and the second arm 13 are also articulated to a vehicle frame, not shown. As can be seen from Figure 1, the first arm 12 and the second arm 13 are arranged crossed, whereby the possible steering angle can be increased. In this case, the spring-damper module 17 is arranged outside the vehicle frame and above the upper transverse link 10.
In Figur 2 ist eine Radaufhängung gezeigt, deren prinzipieller Aufbau dem Aufbau der in Figur 1 gezeigten Radaufhängung entspricht, mit dem Unterschied, dass anstelle des Feder-Dämpfer-Moduls 17 ein separater Dämpfer 18 und eine separate Luftfeder 19 verwendet werden. Auch in diesem Fall ist die Luftfeder 19 außerhalb des Fahrzeugrahmens und oberhalb des oberen Querlenkers 10 angeordnet.In Figure 2, a suspension is shown, the basic structure of which corresponds to the structure of the suspension shown in Figure 1, with the difference that instead of the spring-damper module 17, a separate damper 18 and a separate air spring 19 are used. Also in this case, the air spring 19 is disposed outside of the vehicle frame and above the upper control arm 10.
In Figur 3 ist ein Feder-Dämpfer-Modul gemäß der DE 102004048828 A1 der Anmelderin dargestellt. Das Feder-Dämpfer-Modul 20 umfasst einen Rollbalg 21 , dessen oberes Ende sich an einer Anschlussplatte 22 abstützt, wobei das andere Ende des Rollbalgs 21 an einem Abrollrohr 23 befestigt ist. Hierbei wird durch den Rollbalg und das Abrollrohr ein Federraum 24 definiert, der mit einer Druckluftversorgung verbunden ist. Des weiteren ist zwischen dem Abroll- rohr 23 und einem Basisteil in der Ausgestaltung eines herkömmlichen Schwingungsdämpfers 25 ein Kugelgelenk 26 angeordnet; die Kolbenstange des Schwingungsdämpfers 25 ist mit 39 bezeichnet.FIG. 3 shows a spring / damper module according to DE 102004048828 A1 of the applicant. The spring-damper module 20 comprises a rolling bellows 21, whose upper end is supported on a connection plate 22, wherein the other end of the rolling bellows 21 is attached to a roll-off tube 23. Here, a spring chamber 24 is defined by the rolling bellows and the rolling tube, which is connected to a compressed air supply. Furthermore, between the roll-off pipe 23 and a base part in the embodiment of a conventional vibration damper 25, a ball joint 26 is arranged; the piston rod of the vibration damper 25 is designated 39.
Das Kugelgelenk 26 weist ein sphäroidisches Lagerelement 27 auf, welches in einer Lagerschale 28 Drehbewegungen und bezogen auf eine Längsachse 29 auch Schwenkbewegungen des Lagerelementes 27 ermöglicht. Die Lagerschale ist radial elastisch ausgeführt und verfügt über zumindest eine Schlitz 30, der sich vom oberen Ende der Lagerschale bis über einen Äquator des Lagerelementes 27 erstrecken. Ferner ist die Lagerschale mittels eines Spannelementes 31 auf das sphäroidische Lagerelement 27 einstellbar.The ball joint 26 has a spheroidal bearing element 27, which allows in a bearing shell 28 rotational movements and relative to a longitudinal axis 29 and pivotal movements of the bearing element 27. The bearing shell is designed to be radially elastic and has at least one slot 30, which extend from the upper end of the bearing shell over an equator of the bearing element 27. Furthermore, the bearing shell by means of a clamping element 31 on the spherical bearing element 27 is adjustable.
Hierbei kann das Spannelement 31 von einem Spannring 32 gebildet sein, der sich an einer Gegenhaltehülse 33 abstützt. In vorteilhafter Weise bilden das Legerelement 27, die Lagerschale 28, der Spannring 32 und die Gegenhaltehülse 33 als Kugelgelenk eine in sich geschlossene Baugruppe. Im montierten Zustand wird das Kugelgelenk von einem Schutzbalg 34 abgedeckt, der am Spannring 32 mittels eines Klemmrings 35 befestigt ist.Here, the clamping element 31 may be formed by a clamping ring 32 which is supported on a counter-holding sleeve 33. Advantageously, the release element 27, the bearing shell 28, the clamping ring 32 and the counter holding sleeve 33 form a self-contained assembly as a ball joint. In the assembled state, the ball joint is covered by a protective bellows 34 which is secured to the clamping ring 32 by means of a clamping ring 35.
Wie Figur 3 zu entnehmen ist, ist am Schwingungsdämpfer 25 ein Winkelring 36 befestigt, wobei zwischen dem Lagerelement 27 und dem Winkelring 36 als Anbauteil des Schwingungsdämpfers eine Dichtung 37 angeordnet ist. Ferner ist eine weitere Dichtung 38 vorgesehen, welche den Federraum 24 und die Lagerschale 28 trennt. Ein derartig ausgeführtes Feder-Dämpfer Modul kann derart eingebaut werden, dass der Schwingungsdämpfer unter dem Kolben frei hervorragt, wobei keine weitere achsseitige Dämpferbefestigung notwendig ist.As can be seen from FIG. 3, an angle ring 36 is fastened to the vibration damper 25, a seal 37 being arranged between the bearing element 27 and the angle ring 36 as an attachment to the vibration damper. Furthermore, a further seal 38 is provided, which separates the spring chamber 24 and the bearing shell 28. Such a designed spring-damper module can be installed such that the vibration damper protrudes freely under the piston, with no further axle-side damper attachment is necessary.
