Description
DEUTSCHESGERMAN
Die Erfindung· bezieht sich auf Gummifederungen für Kraftfahrzeuge mit durch die Radachse senkrecht zur Fahrbahn auf Druck belastetem Gummikörper und hat den Zweck, eine bei jeder Belastung gleichmäßige Abfederung von Kraftfahrzeugen zu gewährleisten.The invention relates to rubber suspensions for motor vehicles with perpendicular through the wheel axle to the roadway on pressure loaded rubber body and has the purpose of a uniform with every load To ensure cushioning of motor vehicles.
Personenkraftwagen besitzen ein ungünstiges Verhältnis vom Zuladegewicht zum Eigengewicht. Eine bei jeder Belastung gleichmäßige Abfederung des Personenwagens dst mit den heute üblichen Federelementen, wie Blatt- Drehstab- oder Schraubenfederung nicht ohne weiteres möglich. Man hat daher versucht, Luftdruckfederungen mit Faltenbalgen einzusetzen. Diese Luftfederungen setzen jedoch oft Luftdruckpumpen sowie Regelsysteme voraus, die den Anschaffungspreis der Personenkraftwagen verteuern, und haben gegenüber den bisher üblichen Federungselementen den Nachteil, daß ihr gutes Arbeiten weitgehend von der Dichtheit der Leitungen und des Faltenbalges abhängt. Durch die beispielsweise von unebenen Fahrbahnen verursachten starken dynamischen Beanspruchungen und durch die auf schlechten Straßen bedingten Schläge kann die Dichtheit der Luftdruckfederungen nicht immer gewährleistet werden.Passenger cars have an unfavorable ratio of payload to dead weight. One with every load uniform suspension of the passenger car dst with the spring elements commonly used today, such as leaf, torsion bar or coil suspension are not easily possible. One has therefore tried Use air pressure springs with bellows. However, these air suspensions often use air pressure pumps as well as control systems that make the purchase price of passenger cars more expensive, and have compared to the previously common suspension elements the disadvantage that their good work largely of depends on the tightness of the lines and the bellows. By, for example, uneven road surfaces caused strong dynamic stresses and caused by those on bad roads The air pressure suspension cannot always be guaranteed to be leak-proof.
Es wurde nun gefunden, daß eine lastunabhängige Federung ohne Benutzung von Druckluft möglich ist. Dies wird bei Gummifederungen der eingangs geschilderten Art erfindungsgemäß durch einen Gummikörper erreicht, der aus einem kreissegmentförmigen Scheibenkörper aus elastischem, gegebenenfalls porigem Kunststoff besteht, dessen eine Radialseite auf der Radachse exzentrisch befestigt ist und dessen Bogenseite eine Verzahnung trägt, in die ein die Chassisbelastung aufnehmendes, drehbar gelagertes Zahnrad eingreift, das sich auf die Verzahnung in die der Chassisbelastung entsprechenden Lage einstellt.It has now been found that load-independent suspension is possible without the use of compressed air. In the case of rubber suspensions of the type described above, this is achieved according to the invention by means of a rubber body achieved, which consists of a circular segment-shaped disk body made of elastic, possibly porous There is plastic, one radial side of which is fastened eccentrically on the wheel axle and the curved side carries a toothing into which a rotatably mounted gearwheel absorbs the chassis load intervenes, which adjusts itself to the toothing in the position corresponding to the load on the chassis.
In der Zeichnung sind Ausführungsbeispiele derartiger Federungen für Kraftfahrzeuge, insbesondere für leichtere Personenkraftwagen, schematisch dargestellt. The drawing shows exemplary embodiments of such suspensions for motor vehicles, in particular for lighter passenger cars, shown schematically.
Gemäß Abb. 1 und 2 ist ein als Fader wirkender kreissegmentförmiger Scheibenkörper 1 aus einem hochelastischen, porigen Kunststoff derart angeordnet, daß die Achslagerung 2 nicht im Zentrum des Kreissegmentes, sondern außermittig auf einer Radialseite vorgesehen ist. Die Einstellung einer beliebigen Federkennlinie geschieht dadurch, daß ein senkrecht über der Achse befindliches Zahnrad 3, auf dem über die Welle 4 die Belastung des Chassis ruht, durch einen Seilzug 5 über eine Seilscheibe 6 auf eine außerhalb des kreissegmentförmigen elastischen Puffers 1 angebrachte Verzahnung 7 in die entsprechende Lage gebracht wird. Ein Hubbegrenzer 8, der unter die Verzahnung? faßt, vermeidet ein Abheben des Zahnrades 3 von der Verzahnung 7 und damit eine Verstel-Gummifederung für KraftfahrzeugeAccording to Fig. 1 and 2, a segment of a circle acting as a fader is in the form of a segment of a circle Disc body 1 made of a highly elastic, porous plastic arranged in such a way that the axle bearing 2 is not provided in the center of the circle segment, but rather off-center on a radial side is. The setting of any spring characteristic is done by placing a perpendicular across the axis located gear 3, on which the load on the chassis rests on the shaft 4, by a Cable 5 via a cable pulley 6 on an elastic buffer 1 attached outside of the circular segment-shaped elastic buffer 1 Toothing 7 is brought into the appropriate position. A stroke limiter 8, which is under the toothing? summarizes, avoids a lifting of the gear 3 from the toothing 7 and thus an adjustable rubber suspension for automobiles

lung der Federvorrichtung bei negativer Belastung. Die an den Enden der Verzahnung 7 angebrachten Begrenzungsstege 9 verhindern ein vollständiges Abrollen des Zahnrades 3.development of the spring device under negative load. The limiting webs attached to the ends of the toothing 7 9 prevent the gear wheel 3 from rolling off completely.
Es ist auch möglich, neben der Exzentrizität der Achslagerung bei unterschiedlicher Einstellung des Zahnrades 3 unterschiedliche Druckverformungskennlinien auf der Verzahnung 7 dadurch zu erzielen, daß man in den porigen, hochelastischen Körper 1 in an sich bekannter Weise Bohrungen oder Löcher 12 anbringt. Die Form der Löcher kann rund, oval od. dgl. sein.It is also possible, in addition to the eccentricity of the axle bearing, with different settings of the To achieve gear 3 different compression deformation characteristics on the toothing 7 in that bores or holes 12 are made in the porous, highly elastic body 1 in a manner known per se. The shape of the holes can be round, oval or the like.
Gemäß Abb. 3 läßt sich die Einstellung der lastunabhängigen Federung dadurch erreichen, daß das Chassis 10 mit seinem veränderlichen Gewicht an einer Abrollvorrichtung 11 aufgehängt ist, die das Zahn rad 3 in die der Belastung des Chassis 10 entsprechende Lage des elastischen Federsegmentkörpers 1 dreht.According to Fig. 3, the setting of the load-independent suspension can be achieved in that the chassis 10 is suspended with its variable weight on an unwinding device 11, which rotates the gear wheel 3 in the position of the elastic segment spring body 1 corresponding to the load on the chassis 10.
