Description
Die Erfindung betrifft eine Lageranordnung für eine Schraubenfeder eines Federbeines eines Kraftfahrzeuges mit den im Oberbegriff des Anspruchs 1 genannten Merkmalen.The invention relates to a bearing arrangement for a coil spring of a shock absorber of a motor vehicle with the features mentioned in the preamble of claim 1.
Lageranordnungen der gattungsgemäßen Art sind bekannt. Diese umfassen einen Lagerteller, der über wenigstens einen, in der Regel mehrere Befestigungsmittel an einer entsprechenden Aufnahme einer Fahrzeugkarosserie befestigt ist. Der Lagerteller besitzt eine Durchgangsöffnung zur Aufnahme einer Kolbenstange eines eine Schraubenfeder aufweisenden Schwingungsdämpfers. Ferner ist eine koaxial zur Durchgangsöffnung verlaufende Abstützfläche für die Schraubenfeder vorgesehen.Bearing arrangements of the generic type are known. These include a bearing plate, which is fastened to at least one, as a rule a plurality of fastening means on a corresponding receptacle of a vehicle body. The bearing plate has a passage opening for receiving a piston rod of a coil spring having a vibration damper. Further, a coaxial with the passage opening extending support surface is provided for the coil spring.
Während des bestimmungsgemäßen Einsatzes des Kraftfahrzeuges und somit der Lageranordnung für eine Schraubenfeder des Kraftfahrzeuges, wirken über die Kolbenstange auf den Lagerteller Kräfte. Insbesondere bei schwierigem Gelände wird die Kolbenstange zu ihrer Längsachse verkippt, so dass die die Kolbenstange aufnehmende Durchgangsöffnung des Lagertellers zum so genannten Ausschlagen neigt. Dieser hiermit einhergehende Verschleiß führt zu einer Minderung der Gebrauchseigenschaften des Schwingungsdämpfers, so dass der Fahrkomfort des Kraftfahrzeuges beeinträchtigt wird. Zumindest die Lagerteller der Lageranordnung sind somit in regelmäßigen Abständen auszutauschen.During the intended use of the motor vehicle and thus the bearing assembly for a coil spring of the motor vehicle, acting on the piston rod on the bearing plate forces. In particular, in difficult terrain, the piston rod is tilted to its longitudinal axis, so that the piston rod receiving through hole of the bearing plate tends to so-called knockout. This associated wear leads to a reduction in the performance characteristics of the vibration, so that the ride comfort of the motor vehicle is impaired. At least the bearing plates of the bearing assembly are thus replaced at regular intervals.
Die gattungsbildende
Der Erfindung liegt die Aufgabe zugrunde, eine Lageranordnung der gattungsgemäßen Art zu schaffen, die sich durch einen einfachen Aufbau auszeichnet und die längere Standzeiten ermöglicht.The invention has for its object to provide a bearing assembly of the generic type, which is characterized by a simple structure and allows longer life.
Erfindungsgemäß wird diese Aufgabe durch eine Lageranordnung mit den in Anspruch 1 genannten Merkmalen gelöst. Dadurch, dass die Durchgangsöffnung des Lagertellers einen kegelstumpfförmigen Wandabschnitt besitzt, die Lageranordnung eine Führungshülse für die Kolbenstange des Schwingungsdämpfers umfasst, deren Außenumfang einen kegelstumpfförmigen Wandabschnitt umfasst, der korrespondierend zu dem kegelstumpfförmigen Wandabschnitt der Durchgangsöffnung des Lagertellers ausgebildet ist, und die Führungshülse eine Durchgangsöffnung besitzt, die die Kolbenstange spielfrei umschließt, wird vorteilhaft möglich, über die Paarung der kegelstumpfförmigen Wandabschnitte eine belastungsbedingte Auslenkung der Kolbenstange von ihrer Lagerachse auszugleichen. Es ist quasi in einfacher Weise eine gelenkige Verbindung zwischen der Kolbenstange und dem Lagerteller geschaffen, die dazu führt, dass ein Auslenken der Kolbenstange nicht mehr zu einem Ausschlagen der Durchgangsöffnung des Lagertellers führt. Somit sind die Standzeiten des Lagertellers und somit der gesamten Lageranordnung deutlich verlängert.According to the invention this object is achieved by a bearing assembly with the features mentioned in claim 1. Characterized in that the passage opening of the bearing plate has a frusto-conical wall portion, the bearing arrangement comprises a guide sleeve for the piston rod of the vibration damper whose outer periphery comprises a frusto-conical wall portion which is formed corresponding to the frusto-conical wall portion of the through hole of the bearing plate, and the guide sleeve has a through hole, which surrounds the piston rod clearance, is advantageously possible to compensate for the mating of the frusto-conical wall sections a load-related deflection of the piston rod from its bearing axis. It is virtually created in a simple manner an articulated connection between the piston rod and the bearing plate, which leads to a deflection of the piston rod no longer leads to a knocking out of the through hole of the bearing plate. Thus, the service life of the bearing plate and thus the entire bearing assembly are significantly extended.
Weitere bevorzugte Ausgestaltungen der Erfindung ergeben sich aus den übrigen, in den Unteransprüchen genannten Merkmalen.Further preferred embodiments of the invention will become apparent from the remaining, mentioned in the dependent claims characteristics.
