Description

Abfederung, insbesondere .für Kraftfahrzeuge D;ie Erfindung bezieht sich - auf eine Abfederung, insbesondere für Kraftfahrzeuge, mit ünabhin:gig ,abgefederten Rädern, die durch Lenker oder- Lenkervierecke an einem um eine Längsachse drehbaren und gegenüber dem Rahmen durch schräg zur senkrechten Längsmittelebene angeordnete, aus ebenen Platten bestehende Gummifedern abgefederten Querträger geführt sind: Es sind Abfederungen für Kraftfahrzeuge mit unabhängigen Rädern bekannt, bei -denen die die Räder tragenden Lenker um einen Längszapfen drehbar am Rahmen -geführt und durch aus ebenen, senkrecht gestellten Platten bestehende Gunmniifedern in der Drshrichtung abgefedert sind. Die Gummifedern dienen hierbei weder zur nachgiebigen Lagerung der Lenker in der Drehrichtung noch aber zur nachgiebigen- Lagerung der Lenker in der Fahrtrichtung. Ihre -Wirkungbleibt einzig und allein auf die Abfederung beschränkt.Suspension, in particular for motor vehicles. The invention relates - on a cushioning, especially for motor vehicles, with ünabhin: gig, cushioned Wheels that can be rotated around a longitudinal axis by means of handlebars or handlebars and opposite the frame by obliquely to the vertical longitudinal center plane, rubber springs made of flat plates are guided by sprung cross members: There are suspension for motor vehicles with independent wheels known, both -denen the handlebars supporting the wheels around a longitudinal pin rotatable on the frame -guided and through gunmill springs consisting of flat, vertically placed plates in the direction of rotation are cushioned. The rubber springs are not used for flexible storage the handlebars in the direction of rotation but for the flexible mounting of the handlebars in the direction of travel. Their effect is limited solely to cushioning.

Ferner sind Abfederungen für Schienenfahrzeuge bekannt, bei denen die an den Achsenden sitzenden Achsnager durch aus ebenen senkrecht gestellten Platten bestehende Gummifedern beiderseits im Rahmen geführt und durch senkrecht gestellte Schraubenfedern in. der Hubrichtung abgefedert sind. Die die Räder tragende Achse ist hierbei zwar in der Fahrzeuglängsrichtung nachgiebig am Rahmen abgestützt, sie bleibt jedoch in. der Hubrichtung. durch die Schraubenfedern metallisch mit dem Rahmen verbunden. Mangels weiterer zur Dreh- und Hubfederung dienenden Gummifedern ist also eine allseitig elas'.tisch nachgiebige Führung und Federung der Achse nicht erzielbar.Furthermore, cushioning for rail vehicles are known in which the axle rods sitting at the axle ends by means of flat, vertical plates existing rubber springs on both sides in the frame and placed vertically Coil springs are cushioned in the direction of stroke. The axle carrying the wheels is supported resiliently on the frame in the longitudinal direction of the vehicle, they However, it remains in the stroke direction. metallic with the Frame connected. In the absence of other rubber springs used for torsion and lifting springs a guide and suspension of the axis that is flexible on all sides is not achievable.

Das Neue der Erfindung besteht darin, daß außer den zur Dreh- und Hubfederung dienenden Gummifedern noch besondere, zur Abstützung in Längsrichtung des Fahrzeugs dienende Gummifedern zwischen den Enden des drehbaren Querträgers und den Rahmenlängsträgern eingefügt sind. Dadurch ist eine allseitig elastische Lageding des Querträgers im Rahmen erreicht, die den unabhängig abgefederten Rädern eine ausreichende Lagefestigkeit gibt. Es gelingt hierbei insbesondere, den drehbaren Querträger unter den in Fahrzeuglängsrichtung auftretenden Kräften verhältnismäßig hart, unter den Dreh- und Hubkräften hingegen verhältnismäßig weich im Rahmen zu führen, eine große Dreh- und Hubnachgiebigkeit also Zeit einer geringen achgiebigkeit in Fahrzeuglängsrichtung zu IN paaren und beide nachgiebigen Lagerungen bequem aufeinander abzustimmen. Die Führung der unabhängig abgefederten Räder wird auf diese Weise nicht nur geräuschfrei gehalten, sondern auch vor übermäßigen Beanspruchungen bewahrt, wobei das als Folgeerscheinung harter Stöße auftretende Rahnienschütteln. vermieden werden 'kann.The novelty of the invention is that, in addition to the rubber springs used for torsion and lift suspension, special rubber springs, which are used for support in the longitudinal direction of the vehicle, are inserted between the ends of the rotatable cross member and the frame side members. This achieves an all-round elastic position of the cross member in the frame, which gives the independently sprung wheels sufficient positional stability. In particular, it is possible to guide the rotatable cross member relatively hard under the forces occurring in the longitudinal direction of the vehicle, but relatively soft under the torsional and lifting forces, pairing a high degree of torsional and lifting flexibility, i.e. a time of low flexibility in the longitudinal direction of the vehicle, to IN and both yielding Conveniently coordinate the bearings with one another. In this way, the guidance of the independently sprung wheels is not only kept free of noise, but also protected from excessive stresses, with the shaking of the rack which occurs as a consequence of hard impacts. can be avoided '.

Der Gegenstand der Erfindung ist in der Zeichnung näher veranschaulicht. Es zeigen: Fig. i die Vorderansicht einer Vorderradabfederung, Fig.2 einen senkrechten Teilschnitt durch diese-in vergrößertem Maßstab und Fig. 3 einen Schnitt längs der Linie III-III in Fig. 2.The subject matter of the invention is illustrated in more detail in the drawing. They show: FIG. 1 the front view of a front wheel suspension, FIG. 2 a vertical view Partial section through this - on an enlarged scale and FIG. 3 shows a section along the Line III-III in Fig. 2.

Das Vorderrad 2 ist durch einen oberen Querlenker 3 und eine untere Querblattfeder 4. unabhängig im Rahmen geführt. Lenker 3 und Feder q. werden von einem Querträger 12 getragen, der um eine Längsachse P. drehbar im Rahmen gelagert ist. Die Querfeder q. isst hierbei in der Mitte des drehbaren Querträgers 12 eingespannt, während das Lagergeh.äuse ga des Querlenkers 3 am Ende I2' des drehbaren Querträgers 12 befestigt ist. In das kastenartig erweiterte hohle Ende 12? des drehbaren Querträgers i2 ragt ein Ansatz 16,1 des Rahmenlängsträgers 16 hinein. Der Ansatz 16,1 bildet das Widerlager für die Gummifedern 18 und 21, 22, unter deren Vermittlung der drehbare Querträger 12 im Rahmen gelagert ist. Die zur Dreh- und Hubfederung dienenden Gummifedern 18 bestehen aus zwei schräg zur senkrechten L:ängsmi.tteleb.ene E angeordneten, ebenen Platten, deren Längsmitteleb.enen S sich in der Längsachse P. schneiden. Die zur Abstützung in Fahrzeuglängsrichtung dienenden ;Gummifedern 21, 22 bestehen aus je zwei senkrecht gestellten, ebenen Platten, die zu beiden Seiten des Ansatzes 16a innerhalb des kastenartigen, hohlen Trägerendes 12a angeordnet sind.The front wheel 2 is guided independently in the frame by an upper wishbone 3 and a lower transverse leaf spring 4. Handlebar 3 and spring q. are carried by a cross member 12 which is rotatably mounted in the frame about a longitudinal axis P. The transverse spring q. eats here clamped in the middle of the rotatable cross member 12, while the bearing housing ga of the wishbone 3 is attached to the end I2 'of the rotatable cross member 12. Into the box-like widened hollow end 12? of the rotatable cross member i2, a projection 16.1 of the frame side member 16 protrudes into it. The approach 16.1 forms the abutment for the rubber springs 18 and 21, 22, under whose mediation the rotatable cross member 12 is mounted in the frame. The rubber springs 18 used for torsion and lift suspension consist of two flat plates which are arranged obliquely to the vertical L: longitudinally centered E and whose longitudinal center planes S intersect in the longitudinal axis P. The rubber springs 21, 22, which are used for support in the longitudinal direction of the vehicle, each consist of two perpendicular, flat plates which are arranged on both sides of the extension 16a within the box-like, hollow support end 12a.

Die am Querträger 12 in Fahrzeuglängsrichtung angreifenden Kräfte (Stoß- und Massenkräfte) werden. von den Gummifedern 21, 22 gleichmäßig so aufgenommen, daß diese hierbei hauptsächlich auf Druck beansprucht sind. Die Gummifedern 2i, 22 sperren hierbei die Enden des Querträgers 12 gegenüber den Rahmenlängsträgern 16 in Fahrzeuglängsrichtung so stark, daß: keine wesentliche Federwi@Icung, wohl aber eine wesentliche Dämpfungswirkung in dieser Richtung vorhanden ist. Greifen indessen an dem Querträger 12 Kräfte quer oder senkrecht zur Fahrtrichtung oder gar Quermomente an, so beanspruchen diese die Gummifedern 21, 22 im wesentlichen nur auf Schub. Diese Beanspruchung liefert daher keinen wesentlichen Anteil zu der durch die Gummifedern 18 bedingten Härte der Quer-, Hub- und Drehfederung des Querträgers 12. Durch die Trennung der zur allseitigen elastischen Lagerung des Querträgers 12 dienenden Gummifedern in solche, 18, die die erwünschte Quer-, Hub-und Drehfederung erleichtern, und in solche. 21, 22, die die unerwünschte Federung in Fahrzeuglängsrichtung erschweren, wird die Radführung lagefest und stoßfrei zugleich gehalten, so daß, das beim Fahren auftretende Rahmenschütteln ausgeschaltet werden kann.The forces acting on the cross member 12 in the longitudinal direction of the vehicle (impact and inertia forces) are. evenly absorbed by the rubber springs 21, 22 in such a way that they are mainly subjected to pressure. The rubber springs 2i, 22 lock the ends of the cross member 12 against the frame side members 16 in the longitudinal direction of the vehicle so strongly that: no significant spring deflection, but a significant damping effect is present in this direction. If, however, forces act transversely or perpendicularly to the direction of travel or even transverse moments on the cross member 12, then these forces the rubber springs 21, 22 essentially only in terms of thrust. This stress therefore does not contribute significantly to the hardness of the transverse, lifting and torsion springs of the cross member 12 caused by the rubber springs 18. , Lifting and torsion suspension facilitate, and in such. 21, 22, which complicate the undesired suspension in the longitudinal direction of the vehicle, the wheel guide is held in a fixed position and shock-free at the same time, so that the frame shaking that occurs when driving can be eliminated.

Die Gummifedern 21, 22 werden im vorgespannten Zustand eingebaut, um ihre federnde Nachgiebigkeit in der Fahrtrichtung zugunsten ihrer dämpfenden Nachgiebigkeit möglichst zti beschränken.The rubber springs 21, 22 are installed in the pretensioned state, about their resilience in the direction of travel in favor of their cushioning Restrict compliance as much as possible.
