Abstract
Description
Die Erfindung betrifft eine Vorrichtung zum Verstellen eines Stabilisators an einer Radaufhängung für Kraftfahrzeuge gemäß dem Oberbegriff des Patentanspruches 1.The invention relates to a device for adjusting a stabilizer on a suspension for motor vehicles according to the preamble of claim 1.
Derartige Vorrichtungen zum Vermindern der Wankneigung von Kraftfahrzeugen zum Beispiel beim Durchfahren von Kurven, etc. mittels zumindest einer Stelleinrichtung, die die Stabilisatorarme des am Aufbau des Kraftfahrzeuges verdrehbar gelagerten Stabilisators anheben oder absenken, sind aus zahlreichen Vorschlägen bekannt. Die Stelleinrichtungen können dabei auf den geteilten, quer verlaufenden Drehstab des Stabilisators, auf dessen Lagerböcke oder auf Koppelstangen wirken, die zwischen der Anbindung der Stabilisatorarme und den Radführungselementen vorgesehen sein können. Problematisch bei den bekannten Stelleinrichtungen können die hohen Stellkräfte, erforderliche Freigänge im Bereich der Radführungselemente und/oder eine Zunahme der ungefederten Massen in den Radaufhängungen sein.Such devices for reducing the tendency to roll of motor vehicles, for example, when driving through curves, etc. by means of at least one adjusting device, which raise or lower the stabilizer arms of the structure of the motor vehicle rotatably mounted stabilizer are known from numerous proposals. The adjusting devices can act on the split, transverse torsion bar of the stabilizer, on the bearing blocks or on coupling rods, which can be provided between the connection of the stabilizer arms and the wheel guide elements. The problem with the known adjusting devices can be the high actuating forces, required clearances in the region of the wheel guide elements and / or an increase in the unsprung masses in the wheel suspensions.
Aufgabe der Erfindung ist es, eine Vorrichtung der gattungsgemäßen Art vorzuschlagen, die baulich und fertigungstechnisch günstig in den Stabilisator integrierbar ist und die ohne Freigangprobleme und aufbautechnische Anpassungen in Kraftfahrzeuge verbaubar und/oder nachrüstbar ist.The object of the invention is to propose a device of the generic type, which is structurally and manufacturably low integratable into the stabilizer and which can be installed and / or retrofitted without clearance problems and structural engineering adjustments in motor vehicles.
Die Lösung dieser Aufgabe gelingt erfindungsgemäß mit den kennzeichnenden Merkmalen des Patentanspruches 1. Vorteilhafte und besonders zweckmäßige Weiterbildungen der Erfindung sind in den weiteren Patentansprüchen angeführt.The solution of this object succeeds according to the invention with the characterizing features of claim 1. Advantageous and particularly expedient developments of the invention are set forth in the further claims.
Erfindungsgemäß wird vorgeschlagen, dass eine, bevorzugt jedoch zwei, Stelleinrichtungen in jeweils einen zweigeteilten Arm des Stabilisators zwischen dessen Anbindung an dem Radführungselement und dem Drehstab integriert sind. Neben einer baulich einfachen Gestaltung des Stabilisators wird erreicht, dass dieser wie bei Stabilisatoren üblich am Aufbau gelagert und an den Radführungselementen angebunden werden kann. Der jeweils eine Armabschnitt kann gegebenenfalls fertigungstechnisch günstig an den quer verlaufenden Drehstab angeformt sein. Der Stabilisator ist zudem mit den integrierten Stelleinrichtungen als Vormontageinheit herstellbar und einfach montierbar.According to the invention it is proposed that one, but preferably two, adjusting devices are integrated in each case a two-part arm of the stabilizer between its connection to the wheel guide element and the torsion bar. In addition to a structurally simple design of the stabilizer is achieved that this can be stored as usual in stabilizers on the structure and connected to the Radführungselementen. The respective one arm section may optionally be formed on the transversely extending torsion bar in terms of manufacturing technology. The stabilizer is also produced with the integrated adjusting devices as a pre-assembly and easy to install.
Die Stelleinrichtung kann in einer ersten Ausführungsvariante der Erfindung durch einen elektrisch betätigten Drehaktuator gebildet sein, dessen Gehäuse an dem einen Armabschnitt und dessen abtreibendes Getriebeelement an dem anderen Armabschnitt angreift. Die aufzubringenden Stellkräfte können durch Abstimmung der jeweiligen Armlängen der geteilten Stabilisatorarme und durch die gewählte Getriebeübersetzung des Drehaktuators vorteilhaft eingestellt werden.The adjusting device may be formed in a first embodiment of the invention by an electrically actuated rotary actuator, the housing engages the one arm portion and its abreibendes gear element on the other arm portion. The actuating forces to be applied can be advantageously adjusted by tuning the respective arm lengths of the split stabilizer arms and by the selected gear ratio of the rotary actuator.
Der Drehaktuator kann dementsprechend insbesondere durch ein stark untersetzendes, elektrisch angetriebenes Planetengetriebe, ein Harmonic drive Getriebe oder ein Zykloidgetriebe mit Übersetzungsverhältnissen von ca. 100 gebildet sein. Daraus resultiert eine besonders gewichtsgünstige Konstruktion mit relativ leichten Elektromotoren und robusten Getriebekomponenten.Accordingly, the rotary actuator can be formed, in particular, by a strongly reducing, electrically driven planetary gear, a harmonic drive gear or a cycloidal gear with gear ratios of approximately 100. This results in a particularly low-weight construction with relatively light electric motors and robust transmission components.
In einer bevorzugten, alternativen Ausgestaltung der Erfindung können die beiden Armabschnitte über ein Schwenkgelenk miteinander verbunden sein, wobei die Stelleinrichtung durch einen Lineartrieb gebildet ist, der an beiden Armabschnitten angreift und deren Winkellage zueinander in sich formstabil verändert.In a preferred, alternative embodiment of the invention, the two arm portions may be connected to each other via a pivot joint, wherein the adjusting device is formed by a linear drive, which acts on both arm portions and their angular position mutually changed dimensionally stable.
Dies wird in einer baulich besonders einfachen Konstruktion dadurch erreicht, dass die Stelleinrichtung mit dem Lineartrieb ein Scherengestänge bildet, bei dem der eine Armabschnitt über das Schwenkgelenk hinaus verlängert ist und gelenkig mit dem Gehäuse des Lineartriebs verbunden ist, dessen Stellstange an dem zweiten Armabschnitt zwischen dem gemeinsamen Schwenkgelenk und der Anbindung am Radführungselement angelenkt ist. Durch eine geeignete Anpassung der zwischen den Gelenkstellen wirksamen Hebellängen können relativ geringe Stellkräfte eingestellt werden, die wiederum den Einsatz leichter, kostengünstiger Lineartriebe ermöglichen.This is achieved in a structurally particularly simple construction in that the adjusting device forms a scissors linkage with the linear drive, in which the one arm section is extended beyond the pivot joint and is pivotally connected to the housing of the linear drive whose adjusting rod is connected to the second arm section between the common pivot joint and the connection to the wheel guide element is articulated. By a suitable adjustment of the lever lengths effective between the hinge points relatively small actuating forces can be adjusted, which in turn allow the use of lighter, less expensive linear actuators.
So kann bevorzugt der Lineartrieb ein elektrisch angetriebener Spindeltrieb oder Schraubtrieb sein, bei dem ein Elektromotor eine Gewindespindel antreibt, die mit einer Stellmutter oder Kugelmutter als Abtrieb zusammenwirkt und der insbesondere selbsthemmend ausgeführt ist.Thus, preferably, the linear drive is an electrically driven spindle drive or screw drive, in which an electric motor drives a threaded spindle, which cooperates with an adjusting nut or ball nut as an output and which is designed in particular self-locking.
Alternativ kann der Lineartrieb eine hydraulisch beaufschlagte, teleskopisch verstellbare Kolben-Zylindereinheit sein, die über eine Druckmittelquelle und ein hydraulisches Steuerventil hydrostatisch betätigbar ist.Alternatively, the linear drive may be a hydraulically actuated, telescopically adjustable piston-cylinder unit, which is hydrostatically actuated via a pressure medium source and a hydraulic control valve.
