Abstract
Description
Die Erfindung betrifft eine Domstrebe zur Verbindung zweier Federbeindome eines Kraftfahrzeugs, wobei die Domstrebe die Funktion einer Zug- bzw. Druckstütze übernimmt, und wobei die Domstrebe längenverstellbar ist und dadurch ein Sturz der zugeordneten Räder veränderbar ist. The invention relates to a strut brace for connecting two spring struts of a motor vehicle, wherein the strut brace assumes the function of a train or pressure support, and wherein the strut brace is adjustable in length and thereby a fall of the associated wheels is variable.
Aus der
Es ist daher Aufgabe der vorliegenden Erfindung, eine vorbekannte Domstrebe derart zu verbessern, dass eine Sturzeinstellung der zugeordneten Räder dynamisch auch während der Fahrt erfolgen kann. It is therefore an object of the present invention to improve a previously known strut bar such that a camber adjustment of the associated wheels can be done dynamically while driving.
Diese Aufgabe wird mit den Merkmalen des Patentanspruchs 1 gelöst. Vorteilhafte Weiterbildungen sind den Unteransprüchen entnehmbar. This object is achieved with the features of claim 1. Advantageous developments are the dependent claims.
Dabei ist vorgesehen, dass die Domstrebe aus teleskopartig ineinander gesteckten Hülsen zweiteilig ausgebildet ist und dass zur Längenverstellung der Domstrebe ein fremdansteuerbarer Aktuator vorgesehen ist, der mit den ineinander gesteckten Hülsen zusammenwirkt und eine Relativbewegung der Hülsen zueinander erzeugt. Durch diese Maßnahme wird erreicht, dass der Sturz der zugeordneten Räder jederzeit und damit auch streckenabhängig einstellbar ist. Vorteile bieten sich dadurch vor allem im Rennsport. It is envisaged that the strut brace telescopically nested sleeves is made in two parts and that for length adjustment of the strut brace a externally controllable actuator is provided which cooperates with the nested sleeves and produces a relative movement of the sleeves to each other. By this measure it is achieved that the fall of the associated wheels at any time and thus also track-dependent adjustable. Advantages are thus offered above all in racing.
Eine vorteilhafte Weiterbildung des Erfindungsgegenstandes sieht vor, dass der Aktuator durch einen Elektromotor und eine vom Elektromotor antreibbare Gewindemutter-Spindel-Anordnung gebildet wird. Dabei wird der Elektromotor vorzugsweise von der ersten Hülse aufgenommen und der Elektromotor treibt die Spindel im Sinne einer Drehbewegung an, während die Gewindemutter der Gewindemutter-Spindel-Anordnung fest mit der anderen Hülse verbunden ist. Mit dieser Maßnahme wird ein sogenanntes Rot-Trans-Getriebe realisiert, das die Rotationsbewegung des Elektromotors in eine Translationsbewegung umsetzt. Alternative Ausführungen, bei denen der Elektromotor koaxial um die erste Hülse herum oder radial beabstandet zur ersten Hülse angeordnet sind, sind ebenfalls denkbar. An advantageous development of the subject invention provides that the actuator is formed by an electric motor and a drivable by the electric motor threaded nut spindle assembly. In this case, the electric motor is preferably received by the first sleeve and the electric motor drives the spindle in the sense of a rotational movement, while the threaded nut of the threaded nut spindle arrangement is firmly connected to the other sleeve. With this measure, a so-called red-trans gear is realized, which converts the rotational movement of the electric motor in a translational movement. Alternative embodiments in which the electric motor coaxially around the first sleeve or radially spaced from the first sleeve are also conceivable.
Eine weitere vorteilhafte Weiterbildung des Erfindungsgegenstandes ist es, dass die Länge der Domstrebe und damit der Sturz der zugeordneten Räder in Abhängigkeit der Fahrzeuggeschwindigkeit, der Quer- und/oder Längsbeschleunigung, des Lenkwinkels oder der Gierrate erfolgt. Durch diese Maßnahme kann der Sturz der zugeordneten Räder dynamisch während der Fahrt unter Berücksichtigung der fahrdynamischen Parameter eingestellt werden. Außerdem sind die Länge der Domstrebe und damit der Sturz der zugeordneten Räder manuell über eine Mensch-Maschinen-Schnittstelle einstellbar. A further advantageous development of the subject invention is that the length of the strut brace and thus the fall of the associated wheels as a function of vehicle speed, the transverse and / or longitudinal acceleration, the steering angle or the yaw rate. By this measure, the fall of the associated wheels can be set dynamically while driving taking into account the driving dynamics parameters. In addition, the length of the strut bar and thus the fall of the associated wheels are manually adjustable via a man-machine interface.
In beiden Fällen ist ein Steuergerät vorgesehen, dem die Fahrzeuggeschwindigkeit, die Quer- und/oder Längsbeschleunigung, der Lenkwinkel, die Gierrate oder der Fahrerwunsch zugeführt werden, wobei das Steuergerät einen optimalen Sturz der zugeordneten Räder berechnet und den Aktuator zur Einstellung des optimalen Sturzes ansteuert. In both cases, a control device is provided to which the vehicle speed, the lateral and / or longitudinal acceleration, the steering angle, the yaw rate or the driver's request are supplied, wherein the control unit calculates an optimal fall of the associated wheels and controls the actuator for setting the optimum camber ,
