Abstract
Ein verstellbarer Stabilisator für ein Fahrwerk weist zwei variabel miteinander gekoppelte Torsionsstabhälften (2, 3) auf, wobei zwischen die Torsionsstabhälften (2, 3) ein Blattfederpaket (14) variabler wirksamer Länge geschaltet ist.An adjustable stabilizer for a chassis has two variably coupled torsion bar halves (2, 3), wherein between the Torsionsstabhälften (2, 3), a leaf spring package (14) of variable effective length is connected.
Description
Die Erfindung betrifft einen für ein Fahrwerk eines Fahrzeugs geeigneten verstellbaren Stabilisator, welcher zwei als Torsionsfedern wirksame Stabilisatorhälften aufweist, die variabel miteinander gekoppelt sind.The invention relates to a suitable for a chassis of a vehicle adjustable stabilizer, which has two effective as a torsion spring stabilizer halves, which are variably coupled together.
Ein Stabilisator als Fahrwerkskomponente eines Kraftfahrzeugs hat die Aufgabe, Radaufhängungen auf beiden Fahrzeugseiten auf definierte Weise miteinander zu koppeln. Hierbei ist eine weiche Kupplung eher für den Geländebetrieb und eine harte Kupplung eher für den Straßenbetrieb geeignet. A stabilizer as a chassis component of a motor vehicle has the task of coupling wheel suspensions on both sides of the vehicle in a defined manner. Here, a soft clutch is more suitable for off-road and a hard clutch rather for road use.

Der Erfindung liegt die Aufgabe zugrunde, einen verstellbaren Stabilisator für ein Fahrwerk eines Kraftfahrzeugs gegenüber dem genannten Stand der Technik insbesondere hinsichtlich eines kompakten, montagefreundlichen Aufbaus bei zugleich hoher Funktionssicherheit weiterzuentwickeln.The invention has for its object to further develop an adjustable stabilizer for a chassis of a motor vehicle relative to the cited prior art, in particular in terms of a compact, easy-to-assemble construction at the same time high reliability.
Diese Aufgabe wird erfindungsgemäß gelöst durch einen verstellbaren Stabilisator mit den Merkmalen des Anspruchs 1. Dieser Stabilisator weist zwei in veränderlicher Weise miteinander gekoppelte Torsionsstabhälften auf, wobei jede Torsionsstabhälfte zur Verbindung mit weiteren Fahrwerkskomponenten vorgesehen ist. Der Begriff „Torsionsstabhälften“ impliziert hierbei nicht zwangsläufig, dass die Torsionsstabhälften identisch dimensioniert sind.This object is achieved by an adjustable stabilizer with the features of
Als Element, mit welchem eine Kopplung zwischen den Torsionsstabhälften in veränderlicher Weise hergestellt ist, ist ein Blattfederpaket vorgesehen. Die Veränderung der Torsionssteifigkeit des Blattfederpakets wird dabei durch die Variation der wirksamen Länge dieses Blattfederpakets erreicht.As a member with which a coupling between the Torsionsstabhälften is made in a variable manner, a leaf spring package is provided. The change in the torsional stiffness of the leaf spring package is achieved by the variation of the effective length of this leaf spring package.
Durch die Anordnung des Blattfederpakets in Längsrichtung der beiden Torsionsstabhälften ist ein besonders kompakter Aufbau des Stabilisators realisierbar. Zur Variation der wirksamen Länge des Blattfederpakets ist in vorteilhafter Ausgestaltung ein Spindeltrieb, insbesondere ein Kugelgewindetrieb, vorgesehen. Der Spindeltrieb umfasst eine Spindelmutter, welche verschiebbar und zugleich verdrehgesichert gegenüber einer der beiden Torsionsstabhälften geführt ist. Die Spindelmutter ist in bevorzugter Ausgestaltung starr mit einem Kulissenstück verbunden, in welchem das Blattfederpaket verschiebbar geführt ist. Das Blattfederpaket wiederum ist mit der anderen Torsionsstabhälfte verbunden.The arrangement of the leaf spring assembly in the longitudinal direction of the two torsion bar halves a particularly compact construction of the stabilizer can be realized. To vary the effective length of the leaf spring package, a spindle drive, in particular a ball screw drive, is provided in an advantageous embodiment. The spindle drive comprises a spindle nut, which is guided displaceably and at the same time secured against rotation with respect to one of the two torsion bar halves. The spindle nut is rigidly connected in a preferred embodiment with a link piece, in which the leaf spring package is guided displaceably. The leaf spring package in turn is connected to the other Torsionsstabhälfte.
Gemäß einer möglichen Weiterbildung ist die Gewindespindel des Spindeltriebs nicht direkt, sondern über ein Getriebe, beispielsweise ein Planetengetriebe, angetrieben. Der direkte oder indirekte Antrieb der Gewindespindel erfolgt vorzugsweise elektrisch, wobei der hierfür vorgesehene Elektromotor in einem Gehäuse des Stabilisators integriert ist. Dieses Gehäuse ist in vorteilhafter Ausgestaltung mit einer der beiden Torsionsstabhälften fest verbunden, wobei auch die Verdrehsicherung der Spindelmutter durch Abstützung an diesem Gehäuse hergestellt ist. According to a possible development, the threaded spindle of the spindle drive is not directly, but via a gear, such as a planetary gear, driven. The direct or indirect drive of the threaded spindle is preferably carried out electrically, wherein the electric motor provided for this purpose is integrated in a housing of the stabilizer. This housing is firmly connected in an advantageous embodiment with one of the two Torsionsstabhälften, wherein the rotation of the spindle nut is made by support on this housing.
Die beiden Torsionsstabhälften sind beispielsweise mittels einer Wälzlagerung, insbesondere einer zweireihigen Kugellagerung, verschwenkbar zueinander gelagert. Hierbei stützt sich die Wälzlagerung vorzugsweise an der Innenwandung des Gehäuses ab, welches mit einer der Torsionsstabhälften fest verbunden ist. Mit einem Innenring oder mehreren Innenringen der Wälzlagerung ist hierbei diejenige Torsionsstabhälfte verbunden, an welcher das Blattfederpaket variabler wirksamer Länge befestigt ist. The two Torsionsstabhälften are for example by means of a rolling bearing, in particular a double-row ball bearing, pivotally mounted to each other. In this case, the roller bearing is preferably supported on the inner wall of the housing, which is fixedly connected to one of the Torsionsstabhälften. With an inner ring or a plurality of inner rings of the roller bearing in this case that Torsionsstabhälfte is connected to which the leaf spring package variable effective length is attached.
