Description

Höhenverstellbares Federlager Height adjustable spring bearing
Die vorliegende Erfindung betrifft ein höhenverstellbares Federlager für eine zwischen einem Fahrzeugaufbau und einem ungefederten Radträger wirksam angeordnete Feder.The present invention relates to a height-adjustable spring bearing for a spring operatively disposed between a vehicle body and an unsprung wheel carrier.
Ein Federträger mit einem höhenverstellbaren Federteller ist aus DE 102 37 644 B4 bekannt geworden. Der Federträger weist einen axial beweglichen Federteller auf, wobei ein Aktuator mit einem Rotor relativ zu seinem Stator eine Drehbewegung erzeugt, die von einem Getriebe in eine Axialbewegung des Federtellers umgesetzt wird. Der Aktuator ist in einem Gehäuse untergebracht, das oberhalb einer Durchgangsöffnung im Fahrzeugaufbau für den Federträger abgestützt ist.A spring carrier with a height-adjustable spring plate has become known from DE 102 37 644 B4. The spring carrier has an axially movable spring plate, wherein an actuator with a rotor relative to its stator generates a rotational movement, which is converted by a transmission in an axial movement of the spring plate. The actuator is housed in a housing which is supported above a passage opening in the vehicle body for the spring carrier.
Aus DE 101 01 694 C5 ist ein weiteres höhenverstellbares Federlager bekannt geworden, das ebenfalls gemeinsam mit dem Aktuator am Fahrzeugaufbau angeordnet ist. Auch hier sind spezielle Veränderungen am Fahrzeugaufbau vorgenommen worden, um das höhenverstellbare Federlager und den Aktuator aufnehmen zu können.From DE 101 01 694 C5 a further height-adjustable spring bearing has become known, which is also arranged together with the actuator on the vehicle body. Again, special changes have been made to the vehicle body to accommodate the height-adjustable spring bearing and the actuator can.
Aus DE 101 44 111 A1 ist eine elektromechanische Niveauregulierung eines Kraftfahrzeuges bekannt geworden, bei dem die obere Anlagestelle der Feder ebenfalls dem Fahrzeugaufbau zugeordnet ist, wobei diese obere Anlagestelle mittels eines Elektroanthebs höhenverstellbar ist. Auch hier sind spezielle Ver- änderungen aufbauseitig am Fahrzeug erforderlich.From DE 101 44 111 A1 an electromechanical level control of a motor vehicle has become known, in which the upper contact point of the spring is also associated with the vehicle body, said upper contact point is height adjustable by means of a Elektroanthebs. Here, too, special modifications are required on the vehicle body side.
Bei manchen Fahrzeugtypen sind aufbauseitige Veränderungen zur Aufnahme eines Aktuators oder eines höhenverstellbaren Federtellers nur unter erschwerten Bedingungen oder aber auch gar nicht möglich, da der Bauraum oftmals derartige Veränderungen nicht zulässt. Aufgabe der vorliegenden Erfindung war es, ein höhenverstellbares Federlager nach den Merkmalen des Oberbegriffs des Anspruchs 1 anzugeben, das auch bei beengten Raumverhältnissen eingebaut werden kann.In some vehicle types body-side changes to accommodate an actuator or a height-adjustable spring plate only under difficult conditions or even not possible because the space often does not allow such changes. Object of the present invention was to provide a height-adjustable spring bearing according to the features of the preamble of claim 1, which can be installed even in confined spaces.
Erfindungsgemäß wird diese Aufgabe durch das höhenverstellbare Federlager gemäß Anspruch 1 gelöst. Dadurch, dass der Aktuator und das verstellbare Federlager auf der Seite des ungefederten Radträgers angeordnet sind, entfallen besondere Maßnahmen zur Aufnahme des Federlagers und des Aktuators am Fahrzeugaufbau. Während bei bekannten Anordnungen regelmäßig das obere Federlager verstellbar ausgeführt wurde, schlägt die Erfindung gerade die Umkehrung der bekannten Anordnung vor, indem das obere Federlager in den Wirkrichtungen der Feder fixiert und das ungedämpfte untere Federlager verstellbar ausgeführt ist.According to the invention this object is achieved by the height-adjustable spring bearing according to claim 1. The fact that the actuator and the adjustable spring bearing are arranged on the side of the unsprung wheel carrier, eliminating special measures for receiving the spring bearing and the actuator on the vehicle body. While in known arrangements regularly the upper spring bearing has been made adjustable, the invention proposes just the reverse of the known arrangement by the upper spring bearing fixed in the directions of action of the spring and the undamped lower spring bearing is made adjustable.
Zweckmäßige Weiterbildungen sind in den Unteransprüchen beschrieben. Nachstehend wird die Erfindung anhand eines in einer einzigen Figur abgebildeten Ausführungsbeispieles näher erläutert.Advantageous developments are described in the subclaims. The invention will be explained in more detail with reference to an embodiment shown in a single figure.
Die einzige Figur zeigt ein höhenverstellbares Federlager 1 im Längsschnitt. Eine als Schraubendruckfeder ausgebildete Feder 2 ist zwischen einem hier nur angedeuteten Fahrzeugaufbau 3 und einem ebenfalls nur angedeuteten ungefederten Radträger 4 angeordnet. Das Federlager 1 ist ein unteres Federlager für die Feder 2, während ein oberes Federlager 5 an einem oberen Federteller 6 ausgebildet ist.The single FIGURE shows a height-adjustable spring bearing 1 in longitudinal section. A trained as a helical compression spring spring 2 is disposed between an only indicated here vehicle body 3 and also also indicated only unsprung wheel carrier 4. The spring bearing 1 is a lower spring bearing for the spring 2, while an upper spring bearing 5 is formed on an upper spring plate 6.
Das untere höhenverstellbare Federlager 1 ist an einen Aktuator 7 angeschlossen, bei dessen Betätigung das untere Federlager 1 entlang der Schraubenachse der Schraubendruckfeder verschiebbar ist.The lower height-adjustable spring bearing 1 is connected to an actuator 7, upon actuation of which the lower spring bearing 1 is displaceable along the screw axis of the helical compression spring.
Der Aktuator 7 weist einen Elektromotor 8 auf, und ein an diesen Elektromotor 8 angeschlossenes Getriebe 9.The actuator 7 has an electric motor 8, and a gear 9 connected to this electric motor 8.
Ein Federbein 10 weist sowohl die Feder 2 als auch ein Stoßdämpferrohr 11 auf, das in üblicher Weise einen Kolben 12 und einen Zylinder 13 umfasst. Das untere Federlager 1 ist auf dem Stoßdämpferrohr 11 angebracht, was nachstehend weiter erläutert wird.A strut 10 has both the spring 2 and a shock absorber tube 11 on, which includes a piston 12 and a cylinder 13 in the usual way. The lower spring bearing 1 is mounted on the damper tube 11, which will be further explained below.
Das Getriebe 9 ist vorliegend als Gewindetrieb, nämlich als Kugelgewindetrieb 14 ausgebildet, wobei eine rohrförmige Gewindespindel 15 drehbar über Wälzlager 16 auf einer Lagerhülse 17 gelagert ist. Die Lagerhülse 17 ist auf dem Mantel des Stoßdämpferrohrs 11 befestigt. Die Gewindespindel 15 ist an ihrem Außenumfang mit einer schraubenförmig ausgebildeten Kugelrille 18 versehen. Eine Spindelmutter 19 ist über Kugeln 20 drehbar auf der Gewindespindel 15 gelagert. Die Kugeln 20 wälzen einerseits an der schraubenförmigen Kugelrille 18 und andererseits an einer korrespondierenden schraubenförmigen Kugelrille 21 in bekannter Weise ab, die am Innenumfang der Spindelmutter 19 ausgebildet ist.The gear 9 is presently designed as a screw, namely as a ball screw 14, wherein a tubular threaded spindle 15 is rotatably supported by roller bearings 16 on a bearing sleeve 17. The bearing sleeve 17 is mounted on the jacket of the shock absorber tube 11. The threaded spindle 15 is provided on its outer circumference with a helical ball groove 18. A spindle nut 19 is rotatably mounted on the threaded spindle 15 via balls 20. The balls 20 roll on the one hand on the helical ball groove 18 and on the other hand on a corresponding helical ball groove 21 in a known manner, which is formed on the inner circumference of the spindle nut 19.
Die Spindelmutter 19 ist mit einem einstückig angeformten Radialbord 22 versehen, der zugleich als Federteller das untere Federlager 1 bildet. Der Figur ist zu entnehmen, dass die Schraubendruckfeder 2 mit ihrem unteren Ende an diesen Radialbord 22 abgestützt ist.The spindle nut 19 is provided with an integrally formed radial board 22, which also forms the lower spring bearing 1 as a spring plate. The figure shows that the helical compression spring 2 is supported at its lower end to this radial board 22.
Die Gewindespindel 15 ist mit einem koaxial angeordneten Zahnkranz 23 versehen, mit dem ein Antriebsritzel 24 des Elektromotors 8 kämmt.The threaded spindle 15 is provided with a coaxial toothed ring 23, with which a drive pinion 24 of the electric motor 8 meshes.
Der Figur ist zu entnehmen, dass sowohl der Aktuator 7 als auch das untere Federlager 1 auf der Seite des ungefederten Radträgers 4 angeordnet sind.The figure shows that both the actuator 7 and the lower spring bearing 1 are arranged on the side of the unsprung wheel carrier 4.
Der Federteller, die Gewindespindel 15, die Lagerhülse 17 sowie das Federbein 10 sind koaxial zueinander angeordnet.The spring plate, the threaded spindle 15, the bearing sleeve 17 and the strut 10 are arranged coaxially with each other.
Auch bei beengten Bauraumverhältnissen ist im Bereich des Stoßdämpferrohres 11 oftmals hinreichend Bauraum zur Verfügung, um den Aktuator neben das Stoßdämpferrohr anzuordnen. Bei Betätigung des Elektromotors 8 wird die Gewindespindel 15 in Rotation versetzt, so dass eine Relativdrehung zwischen der Spindelmutter 19 und der Gewindespindel 15 einsetzt. Unter dieser Relativdrehung wird die Spindelmutter 19 - und somit das Federlager 1 - entlang der Achse des Federbeins ver- schoben, so dass eine Niveauregulierung des Fahrzeugaufbaus erreicht wird. Am oberen Federlager 5 sind zur Umsetzung der Erfindung keine besonderen Maßnahmen erforderlich.Even in confined space conditions, sufficient space is often available in the area of the shock absorber tube 11 in order to arrange the actuator next to the shock absorber tube. Upon actuation of the electric motor 8, the threaded spindle 15 is set in rotation, so that a relative rotation between the spindle nut 19 and the threaded spindle 15 begins. Under this relative rotation, the spindle nut 19 - and thus the spring bearing 1 - is displaced along the axis of the shock absorber, so that a level control of the vehicle body is achieved. At the upper spring bearing 5 no special measures are required to implement the invention.
Die vorliegende Erfindung kann in günstiger Weise mit einer so genannten Fail-Safe-Einrichtung versehen sein. Bei unbestromten Motor kann diese FaN- Safe-Einrichtung aktiviert sein. Sie verhindert bei abgeschaltetem Elektromotor ein unerwünschtes Rotieren der Spindelmutter 19 und somit ein unerwünschtes Absinken des unteren Federlagers 1.The present invention can be conveniently provided with a so-called fail-safe device. When the motor is not energized, this FaN-Safe device can be activated. It prevents unwanted rotation of the spindle nut 19 and thus an undesirable lowering of the lower spring bearing 1 when the electric motor is switched off.
Besondere Maßnahmen zur rotatorischen Fixierung des unteren Federlagers 1 sind nicht erforderlich, da zwischen dem unteren Ende der Schraubendruckfeder 2 und dem Federteller - der zugleich die Gewindespindel 15 bildet - aufgrund von Haftreibung ein Verdrehung verhindert ist.Special measures for rotational fixation of the lower spring bearing 1 are not required, as between the lower end of the helical compression spring 2 and the spring plate - which also forms the threaded spindle 15 - due to static friction rotation is prevented.
Das untere verstellbare Federlager und der Aktuator können auch beispielsweise an einem - ebenfalls ungefederten - Radlenker angebracht werden. The lower adjustable spring bearing and the actuator can also be mounted, for example, on a - also unsprung - Radlenker.
