Description
Abstützung eines aus einem Stoßdämpfer und insbesondere aus einer Schraubenfeder bestehenden Federbeines am Rahmen eines Kraftfahrzeuges Die Erfindung betrifft die Abstützung eines aus einem Stoßdämpfer und insbesondere aus einer Schraubenfeder bestehenden Federbeines am Rahmen eines Kraftfahrzeuges mit Hilfe elastischer Mittel, wie z. B. Gummi oder technisch gleichwertiger Stoffe, die als auf beiden Seiten des Federtellers für die Feder angeordnete elastische Puffer ausgebildet sind, deren oberer Puffer sich in der Mulde eines rahmenfesten Tragbleches abstützt.Support of a shock absorber and in particular a Coil spring existing strut on the frame of a motor vehicle The invention relates to the support of a shock absorber and in particular a coil spring existing strut on the frame of a motor vehicle with the help of elastic means, such as B. rubber or technically equivalent substances that are considered on both sides of the spring plate arranged for the spring elastic buffers are formed, the upper buffer is supported in the recess of a frame-fixed support plate.
Durch die französische Patentschrift 1189 165 ist ein Federbein obiger Art bekannt, das durch getrennte Gummipuffer oberhalb und unterhalb des Federtellers am Rahmen abgestützt ist. Dabei nimmt der obere Puffer die Abstützkräfte auf und der untere dient als elastischer Anschlag bzw. Zusatzfeder. Diese Ausbildung ist umständlich in der Fertigung, da die Gummipuffer mit dem Federteller durch besondere Maßnahmen, z. B. durch einen Haftvorgang, verbunden sein müssen. Außerdem besteht keine Geräuschisolierung zwischen Feder und Federteller.A suspension strut of the above type is known from French patent specification 1189 165, which is supported on the frame by separate rubber buffers above and below the spring plate. The upper buffer absorbs the supporting forces and the lower one serves as an elastic stop or additional spring. This training is cumbersome to manufacture because the rubber buffer with the spring plate by special measures, such. B. must be connected by an arrest process. In addition, there is no noise isolation between the spring and the spring plate.
Die Erfindung bezweckt eine Verbesserung der Abstützung eines solchen Federbeines, und es sollen vor allem die vorstehend geschilderten Nachteile vermieden werden. Sie löst die gestellte Aufgabe bei den eingangs erwähnten Anordnungen dadurch, daß beide Puffer miteinander verbunden sind - wie an sich bekannt - und für die Verbindung beider Puffer Aussparungen im Federteller angeordnet sind, die vom Material der Puffer durchsetzt sind, und daß ferner der untere Puffer eine flanschartige Randzone aufweist, die sich bis in den Bereich zwischen Feder und Federteller erstreckt.The invention aims to improve the support of such Strut, and it should above all avoid the disadvantages outlined above will. It solves the task at hand in the above-mentioned arrangements by that both buffers are connected to each other - as is known per se - and for the Connection of both buffers recesses are arranged in the spring plate, which are made of the material the buffer are penetrated, and that furthermore the lower buffer is a flange-like one Has edge zone which extends into the area between the spring and spring plate.
Durch die deutsche Patentanmeldung G 4124 sind zwar zwei miteinander verbundene Puffer bereits bekanntgeworden. Dort übernimmt eine zentrale, die Kolbenstange umschließende Hülse aus dem Material der Puffer die Verbindung. Dieser Hals durchsetzt auch das Befestigungsloch des Tragbleches, wobei der Federteller unterhalb des unteren Puffers angeordnet ist. Dies bietet Schwierigkeiten in der Montage und ist außerdem nicht in allen Fällen durchführbar, nämlich dann nicht, wenn die beide Puffer durchsetzende Kolbenstange am Federteller befestigt sein muß.By the German patent application G 4124 two are with each other connected buffer already known. There a central one, the piston rod, takes over enclosing sleeve made of the material of the buffer the connection. This throat runs through also the mounting hole of the support plate, with the spring plate below the lower one Buffer is arranged. This presents difficulties in assembly and is also not feasible in all cases, namely not when the two buffers enforce The piston rod must be attached to the spring plate.
Die Erfindung hat den Vorteil, daß die beiden elastischen Puffer in demselben Arbeitsgang ohne besondere zusätzliche Maßnahmen zur Befestigung am Federteller, wie es z. B. in der Gummimetalltechnik bisher durch Kleben oder Anvulkanisieren notwendig war, hergestellt werden können. Außerdem ist sie in allen Fällen anwendbar und ergibt eine Geräuschisolierung zwischen Feder und Federteller.The invention has the advantage that the two elastic buffers in the same work step without special additional measures for fastening to the spring plate, how it z. B. in rubber-metal technology so far by gluing or vulcanization was necessary, can be produced. It is also applicable in all cases and results in noise isolation between the spring and the spring plate.
Die beiden Puffer können prinzipiell - wie bekannt - aus gleichem, und zwar aus jedem elastischen Material bestehen. Zweckmäßigerweise wird erfindungsgemäß ein an sich bekannter Schaumstoff verwendet. Dabei ist es denkbar, daß der obere Puffer eine größere Härte aufweist als der untere, die bei Schaumstoff durch verschieden starke Blasenbildung erzielt werden kann. Weiterhin ist es denkbar, daß der obere Puffer und bzw. oder die Mulde am Tragblech für eine zunehmende Federhärte beim Einfedern in an sich bekannter Weise derart als Abwälzflächen geformt sind, daß sich der Puffer beim Einfedern in zunehmendem Maße am Tragblech abstützt.The two buffers can in principle - as known - consist of the same, namely consist of any elastic material. Expediently, according to the invention a known foam is used. It is conceivable that the upper The buffer has a greater hardness than the lower one, which differs in the case of foam severe blistering can be achieved. It is also conceivable that the upper Buffer and / or the trough on the support plate for increasing spring stiffness when Compression in a manner known per se are shaped as rolling surfaces in such a way that the buffer is increasingly supported on the support plate during compression.
In der Zeichnung ist ein Ausführungsbeispiel der Erfindung an Hand einer im Querschnitt dargestellten Federbeinabstützung gezeigt.In the drawing, an embodiment of the invention is on hand a strut support shown in cross section.
Nach der Zeichnung besteht das Federbein in an sich bekannter Weise aus einem Stoßdämpfer 10 und der ihn konzentrisch umgebenden Schraubenfeder 11. Beide Teile sind unten in nicht dargestellter, aber an sich bekannter Weise an der Radaufhängung, z. B. an einem Querlenker angelenkt. Oben ist die Kolbenstange 12 des Stoßdämpfers mit dem Federteller 13 fest verbunden. Hierfür ist der Federteller 13 mit einer Hülse 14 z. B. verschweißt oder vernietet, welche ihrerseits mit einer Mutter 15 auf der Kolbenstange 12 festgelegt wird.According to the drawing, the strut consists in a manner known per se of a shock absorber 10 and the helical spring 11 surrounding it concentrically. B. hinged to a wishbone. At the top, the piston rod 12 of the shock absorber is firmly connected to the spring plate 13. For this purpose, the spring plate 13 is provided with a sleeve 14, for. B. welded or riveted, which in turn is fixed with a nut 15 on the piston rod 12.
Der Federteller 13 hat Aussparungen 16, die am ganzen Umfang gleichmäßig verteilt sind. Am Federteller befindet sich ein oberer elastischer Puffer 17 und ein unterer elastischer Puffer 18, die durch die soeben erwähnten Aussparungen 16 miteinander in Verbindung stehen. Bei der Herstellung läuft das Material beider Puffer zusammen. Normalerweise bestehen beide Puffer aus demselben Material und es kommt hierfür vorzugsweise ein elastischer Schaumstoff, z. B. aus Polyurethan, in Frage. Eine besondere Befestigung der Puffer am Federteller, etwa durch Kleben od. dgl., ist an sich nicht mehr nötig.The spring plate 13 has recesses 16 which are evenly distributed over the entire circumference. On the spring plate there is an upper elastic buffer 17 and a lower elastic buffer 18, which are connected to one another through the recesses 16 just mentioned. During production, the material from both buffers converges. Usually both buffers are made of the same material and an elastic foam, e.g. B. made of polyurethane, in question. A special fastening of the buffers on the spring plate, for example by gluing or the like, is no longer necessary per se.
Der obere Puffer 17 stützt sich in der Mulde 20 eines Tragbleches 19 ab, welches zur Rahmenkonstruktion des Fahrzeuges gehört bzw. am Rahmen befestigt ist. Die Seitenflächen 21 des Puffers 17 und die der Mulde 20 dienen dabei als Abwälzflächen, wodurch in bekannter Weise eine progressive Federhärte erzielt werden kann.The upper buffer 17 is supported in the trough 20 of a support plate 19, which belongs to the frame structure of the vehicle or is attached to the frame is. The side surfaces 21 of the buffer 17 and those of the trough 20 serve as rolling surfaces, whereby a progressive spring stiffness can be achieved in a known manner.
Der untere Puffer 18 dient als Anschlag gegenüber dem Deckel 22 des Stoßdämpfers 10. Der Puffer 18 erstreckt sich mit einer flanschartigen Randzone 23 bis in den Bereich zwischen der Feder 11 und dem Federteller 13, so daß dadurch eine weitere Geräuschisolierung erzielt werden kann.The lower buffer 18 serves as a stop against the cover 22 of the Shock absorber 10. The buffer 18 extends with a flange-like edge zone 23 to the area between the spring 11 and the spring plate 13, so that thereby further noise isolation can be achieved.
