Description

Die Erfindung bezieht sich auf einen federnden Träger für Stoßstangen an Kraftfahrzeugen. Das Neue besteht darin, daß als Träger für die Stoßstange federnde Bänder verwendet sind, die zusammen einen hohlkugelartigen Körper bilden, in dessen Innern in Fahrtrichtung einander gegenüberliegende elastische Puffer angeordnet sind, die in der Ruhelage der Träger sich nxht berühren. Die ίο Bänder sind an gegenüberliegenden starren kalottenförmigen Körpern befestigt. Der besondere Vorteil der Vorrichtung besteht darin, daß der Stoß aus beliebiger Richtung kommen kann.The invention relates to a resilient support for bumpers on motor vehicles. The novelty is that resilient bands are used as a support for the bumper, which together form a hollow sphere Form body, in the interior of which in the direction of travel opposing elastic buffers are arranged in the The rest position of the carriers do not touch each other. The ίο ligaments are rigid on opposite sides Dome-shaped bodies attached. The particular advantage of the device is that that the shock can come from any direction.

Die Vorrichtung nach der Erfindung ist geeignet, selbst bei starken Zusammenstößen und unter ungünstigsten Bedingungen Stöße, die sonst das Fahrzeug in Mitleidenschaft ziehen würden, zu dämpfen und unwirksam zu machen. Bei starken Stößen werden die im Innern angeordneten Puffer mehr oder weniger gegeneinandergepreßt. Diese tragen somit gleichfalls zur Dämpfung des Stoßes bei. Der Erfindungsgegenstand ist in den Zeichnungen in mehreren Ausführungsbeispielen dargestellt. Es zeigt:The device according to the invention is suitable even in the event of severe collisions and, under the most unfavorable conditions, shocks that would otherwise affect the vehicle would drag, dampen and render ineffective. In the event of strong impacts, the im Inside arranged buffer more or less pressed against each other. These therefore carry also at the damping of the shock. The subject of the invention is in the drawings shown in several embodiments. It shows:

Fig. ι eine Seitenansicht,
Fig. 2 eine Ansicht der Vorrichtung von vorn,
Fig. Ι a side view,
Fig. 2 is a view of the device from the front,

Fig. 3 die Vorrichtung bei geringem Stoß, Fig. 4 bei starkem Stoß,
Fig. 5 eine andere Form der Vorrichtung, Fig. 6 eine Ansicht dieser von vorn und
Fig. 7 bei einem schräg gerichteten Stoß. Die Vorrichtung besteht aus Bändern-1, z. B. Stahlbändern, die zusammen eine Kugel, ein Ellipsoid ο. dgl. bilden. Bei der kugelförmigen Ausbildung nach Fig. 1 bilden die Bänder einen Kreis und werden gemeinsam mittels eines Bolzens 5 an kalottenförmigen Metallkörpern 2 bzw. 2' befestigt. Die Kalotten werden an der Stoßstange bzw. am Rahmen des Fahrzeuges mittels Schraubenbolzen 6 befestigt. Die federnden Bänder werden auf den Kalotten durch Bolzen 3 in ihrer Lage gehalten, damit sie sich nicht um ihren Durchmesser drehen können. Im Innern der Kalotten sind gegenüberliegende elastische Puffer 4 z. B. aus Kautschuk angebracht.
Fig. 3 shows the device in the case of a slight shock, Fig. 4 in the case of a strong shock,
FIG. 5 shows another form of the device, FIG. 6 shows a view of this from the front and FIG
7 with an obliquely directed impact. The device consists of tapes-1, e.g. B. Steel bands that together form a sphere, an ellipsoid ο. like. Form. In the spherical design according to FIG. 1, the bands form a circle and are fastened together by means of a bolt 5 to dome-shaped metal bodies 2 and 2 '. The domes are attached to the bumper or to the frame of the vehicle by means of screw bolts 6. The resilient bands are held in their position on the calottes by bolts 3 so that they cannot turn around their diameter. In the interior of the domes opposing elastic buffers 4 z. B. made of rubber.

Beim Ausführungsbeispiel nach Fig. 5 hat die Vorrichtung die Gestalt eines Ellipsoids. Die einzelnen Bänder, die in einer Diametralebene liegen, bestehen hier aus zwei Teilen, deren Enden polartig zusammentreffen und mittels Schrauben, Nieten o. dgl. an kalottenförmigen Körpern 2 oder 2', ähnlich wie in Fig. 1 dargestellt, befestigt sind. Innerhalb der Vorrichtung sind gleichfalls kalottenförmige Teile vorgesehen, die mit den äußeren Kalotten 2 oder 2' durch Schrauben o. dgl. verbunden sind, so daß die federnden Bänder 1 zwischen den beiden Kappen gefaßt werden. Hierdurch wird eine sichere Befestigung der Bänder erreicht. Auch bei dieser Ausführungsform sind im Innern Puffer befestigt.In the embodiment according to FIG. 5, the device has the shape of an ellipsoid. The individual bands, which lie in a diametrical plane, here consist of two parts, the ends of which meet like a pole and by means of screws, rivets or the like on dome-shaped bodies 2 or 2 ', similarly as shown in Fig. 1, are attached. Inside the device are also dome-shaped Parts provided with the outer calottes 2 or 2 'by screws o. The like. Are connected so that the resilient strips 1 taken between the two caps will. This ensures that the straps are securely fastened. Even with this one Embodiment are attached inside buffers.
