Abstract
Description
Die Erfindung betrifft eine Anhängerkupplung gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a trailer coupling according to the generic term of claim 1.
Aus der
Der Erfindung liegt die Aufgabe zugrunde, eine Anhängerkupplung der eingangs genannten Art zu schaffen, die eine hohe Belastbarkeit aufweist.The invention has for its object a trailer hitch of the type mentioned at the beginning to create a high resilience having.
Diese Aufgabe wird erfindungsgemäß mit den Merkmalen des Patentanspruchs 1 gelöst.This object is achieved with the Features of claim 1 solved.
Die Anhängerkupplung gemäß Anspruch 1 weist eine am Fahrzeug gehaltene Platte auf, die ein Kupplungsglied trägt. Dieses Kupplungsglied dient zur Verbindung mit einem Anhänger, insbesondere einer Anhängerdeichsel. Zur Erzielung einer hohen Belastbarkeit der Anhängerkupplung ist die Platte zusammen mit dem Kupplungsglied einstückig erstellt. Auf diese Weise ist sichergestellt, daß die Verbindungsstelle zwischen dem Kupplungsglied und der Platte hohen Stütz- bzw. Zugbelastungen standhält. Ein Ausreißen eines Gewindes bzw. Brechen einer Schweißnaht ist durch die einstückige Herstellung des Kupplungsglieds mit der Platte zuverlässig unterbunden. Zugunsten der hohen Belastbarkeit der Anhängerkupplung wird dabei eine aufwendigere Herstellung der Anhängerkupplung in Kauf genommen.The trailer hitch according to claim 1 has a plate held on the vehicle, which is a coupling member wearing. This coupling member is used to connect to a trailer, especially one Trailer tongue. The plate is to achieve a high load capacity of the trailer coupling created in one piece with the coupling member. In this way it is ensured that the High connection point between the coupling member and the plate supporting or withstands tensile loads. On tear a thread or breaking of a weld is through the one-piece production of Coupling member reliably prevented with the plate. In favor of the high load capacity of the towbar a more complex manufacture of the trailer coupling is accepted.
Zur Erzielung einer maximalen Belastbarkeit der Anhängerkupplung ist es gemäß Anspruch 2 vorteilhaft, wenn die Platte zusammen mit dem Kupplungsglied als ein einstückiges Schmiedeteil erstellt ist. Ein Schmiedeteil zeichnet sich durch eine hohe Festigkeit aus, da die Kristallite durch den Schmiedevorgang unterbrechungsfrei von der Platte in das Kupplungsglied übergehen. Im Gegensatz zu einem Gußteil weist das Schmiedeteil den weiteren Vorteil auf, daß es eine geringe Sprödigkeit besitzt und folglich auch gegen Stoßbelastungen, wie sie während der Fahrt auftreten können, resistent ist.To achieve maximum resilience trailer hitch it is according to claim 2 advantageous if the plate together with the coupling member a one piece Forgings is created. A forged part is characterized by a high strength because the crystallites through the forging process Transition from the plate into the coupling element without interruption. In contrast to a cast part the forged part has the further advantage that it is a low brittleness has and consequently also against shock loads, such as during the Ride can occur is resistant.
Gemäß Anspruch 3 ist es vorteilhaft, wenn das Kupplungsglied mit einem gerundeten Übergang an der Platte angeformt ist. Dadurch werden Spannungen des Kupplungsglieds aufgrund von Stütz- und Zuglasten optimal in die Platte eingeleitet, ohne daß im Übergangsbereich zwischen beiden zum Bruch führende Spannungsüberhöhungen auftreten.According to claim 3, it is advantageous if the coupling member is formed on the plate with a rounded transition is. As a result, tensions of the coupling member due to Support and Tensile loads optimally introduced into the plate without the transition area between the two leading to breakage Stress increases occur.
Um die Platte und damit das einstückig mit ihr verbundene Kupplungsglied leicht austauschen zu können, ist es gemäß Anspruch 4 günstig, wenn die Platte mit ihren Randbereichen am Fahrzeug gehalten ist. Vorzugsweise greifen die einander gegenüberliegenden seitlichen Randbereiche der Platte in eine Nut zweier vertikal ausgerichteter Wangen ein, so daß die Platte leicht in diese Nut einschiebbar ist. Um der Platte eine ausreichende Festigkeit zu verleihen, ist sie in einem Bereich außerhalb dieser Randbereiche wenigstens teilweise verstärkt ausgebildet. Diese Verstärkung beeinträchtigt daher nicht die Festlegung der Platte am Fahrzeug.To the plate and thus in one piece with it connected coupling member can be easily replaced it according to claim 4 cheap, if the edge of the plate is held on the vehicle. The mutually opposite lateral edge regions preferably grip the plate in a groove of two vertically aligned cheeks, so that the Plate can be easily inserted into this groove. To the plate one To give sufficient strength, it is in an area outside this edge regions are at least partially reinforced. This reinforcement therefore affects not fixing the plate on the vehicle.
Um die Platte am Fahrzeug zu fixieren, weist diese gemäß Anspruch 5 mindestens eine Bohrung auf, die von einem Stift durchsetzt ist. Vorzugsweise ist wenigstens einer der Stifte als Exzenterstift ausgebildet, um eine spielfreie Festlegung der Platte zu gewährleisten. In einem Bereich um diese Bohrung ist die Verstärkung der Platte ausgespart, um die Festlegung der Platte durch den Stift in keiner Weise zu behindern.To fix the plate to the vehicle, assigns this according to claim 5 at least one hole that is penetrated by a pin. At least one of the pins is preferably designed as an eccentric pin, to ensure a play-free fixing of the plate. In one area around this hole is the reinforcement the plate is recessed to help fix the plate through the pin in no way to hinder.
Schließlich ist es gemäß Anspruch 6 günstig, wenn das Kupplungsglied ein Kugelkopf oder ein Piton ist. Diese Kupplungsgliedformen gewährleisten ein sehr einfaches Ankuppeln eines Anhängers, wobei das Kupplungsglied selbst unbeweglich ist. Insbesondere ein Kugelkopf gewährleistet außerdem eine spielfreie Ankupplung, so daß vom Anhänger keinerlei Schläge auf das Fahrzeug übertragen werden.Finally, it is according to claim 6 cheap if the coupling member is a ball head or a piton. These coupling link shapes ensure a very simple coupling of a trailer, the coupling link itself is immobile. In particular, a ball head ensures also one backlash-free coupling, so that from No followers beating transferred to the vehicle become.
