Abstract
Description
Federbeinlager sind Teil der Radaufhängung bei Einzelradaufhängungen. Die Radaufhängung unterstützt eine angestrebte Fahrsicherheit und Fahrkomfort, sowie ein leichtes und präzises Lenken der Räder. Die an den Reifenaufstandspunkten auftretenden Kräfte zum Fahrzeugaufbau werden über das Federbein übertragen. Die Radaufhängung soll Fahrbahngeräusche vom Aufbau fernhalten und möglichst leicht sein. Das Federbeinlager nimmt Radial- und Axialkräfte auf und sorgt dafür, dass sich die Stoßdämpfer-Feder beim Lenken und Einfedern reibungsarm und verspannungsfrei verdreht und so ohne Rückstellmoment arbeitet. Je nach Ausführung führt das Federbeinlager die Stoßdämpfer-Feder und bildet eine Stützfläche für den Stoßdämpfer-Endanschlag. Das Federbeinlager nimmt die über die oft als Schraubendruckfeder ausgeführte Stoßdämpfer-Feder übertragenen Kräfte auf sowie gegebenenfalls die von dem Stoßdämpfer übertragenen Kräfte. Strut bearings are part of the suspension for independent suspension. The suspension supports a desired driving safety and driving comfort, as well as easy and precise steering of the wheels. The forces occurring at the tire contact points to the vehicle body are transmitted via the shock absorber. The suspension should keep road noise from the structure and be as light as possible. The strut bearing absorbs radial and axial forces and ensures that the shock absorber spring rotates frictionless and tension-free during steering and compression, thus working without restoring moment. Depending on the version, the suspension strut bearing guides the shock absorber spring and forms a support surface for the shock absorber end stop. The suspension strut bearing absorbs the forces transmitted via the shock absorber spring, which is often designed as a helical compression spring, and possibly also the forces transmitted by the shock absorber.
Ein erfindungsgemäßes Federbeinlager ist mit einer Kappe versehen, die an dem chassisseitigen Federbeindom befestigt ist, sowie mit einem Führungsring, an dem die Stoßdämpfer-Feder abgestützt ist, wobei die Stoßdämpfer-Feder an dem Führungsring geführt ist. Der Führungsring ist gegenüber der Kappe um eine Drehachse herum drehbar gelagert. Diese drehbare Lagerung des Führungsrings ermöglicht Drehbewegungen der vorzugsweise als Schraubendruckfeder ausgeführten Schraubendruckfeder gegenüber der Kappe.An inventive strut bearing is provided with a cap which is fixed to the chassis-side strut tower, and with a guide ring on which the shock absorber spring is supported, wherein the shock absorber spring is guided on the guide ring. The guide ring is rotatably mounted relative to the cap about an axis of rotation. This rotatable mounting of the guide ring allows rotational movements of the preferably designed as a helical compression spring helical compression spring relative to the cap.
Erfindungsgemäße Federbeinlager sind oftmals Teil der sogenannten McPherson-Federbeine. Ein MacPherson-Federbein ist zusammen mit dem Querlenker, der Schubstrebe/Stabilisator und der Spurstange ein komplettes Radaufhängungssystem. Das Federbein besteht im Wesentlichen aus Feder, Stoßdämpfer und Achsschenkel. Bei einfachen Ausführungen ist nicht nur der untere Federteller, sondern auch der Achsschenkel mit dem Zylinder des hydraulischen Stoßdämpfers verschweißt. Mit dem Federbein verschraubte Achsschenkel ermöglichen hingegen das Einstellen des Sturzes. Der obere Federteller ist im sogenannten Federbeindom in der Karosserie über das Federbeinlager gelagert, Das Lager ermöglicht beim Lenken ein Drehen der Feder gegenüber der Karosserie, denn bei Lenkbewegungen dreht sich das gesamte Federbein.Inventive strut bearings are often part of the so-called McPherson struts. A MacPherson strut, along with the wishbone, pushrod / stabilizer and tie rod, is a complete suspension system. The strut consists essentially of spring, shock absorbers and steering knuckle. In simple embodiments, not only the lower spring plate, but also the steering knuckle is welded to the cylinder of the hydraulic shock absorber. On the other hand, stub axles bolted to the strut make it possible to adjust the camber. The upper spring plate is mounted in the so-called Federbeindom in the body via the suspension strut bearing, the bearing allows when turning a rotation of the spring relative to the body, because during steering movements, the entire strut rotates.
Aus
Aufgabe der vorliegenden Erfindung war es, ein Federbeinlager nach den Merkmalen des Oberbegriffs des Anspruchs 1 anzugeben, dass einfach ausgeführt ist.Object of the present invention was to provide a suspension strut bearing according to the features of the preamble of claim 1 that is simple.
Erfindungsgemäß wurde diese Aufgabe durch das Federbeinlager gemäß Anspruch 1 gelöst. Dadurch, dass die Schnappverbindung örtlich zwischen dem Axiallager und dem Radiallager angeordnet ist, ergeben sich die folgenden Vorteile: zunächst kann die Kappe axial kürzer bauen, da die kappenseitige Schnappverbindung nicht länger an einem axialen Ende der Kappe angeordnet ist. Ferner ist die Schnappverbindung aufgrund ihrer Anordnung im Inneren des Federbeinlagers vor äußeren Einflüssen wie Stößen oder Verunreinigungen besser geschützt.According to the invention this object has been achieved by the suspension strut bearing according to claim 1. The fact that the snap connection is arranged locally between the thrust bearing and the radial bearing offers the following advantages: first, the cap can be made shorter axially, since the cap-side snap connection is no longer located at one axial end of the cap. Furthermore, the snap connection is better protected due to their location in the interior of the strut bearing from external influences such as shocks or contamination.
Vorzugsweise sind die Kappe und/oder der Führungsring aus Kunststoff im Spritzverfahren einfach und kostengünstig hergestellt. Die Schnappverbindung kann ineinandergreifende erste und zweite Schnappmittel aufweisen, die derart ineinandergreifen, dass die Kappe und der Führungsring mit dem Radiallager sowie mit dem Axiallager als Baueinheit zusammengehalten sind. Die ersten Schnappmittel können federelastisch auslenkbare Schnappnasen sein. Die zweiten Schnappmittel können durch Vorsprünge und / oder Ausnehmungen gebildet sein, wobei die Schnappnasen die Vorsprünge hintergreifen und / oder in die Ausnehmungen einschnappen. Als Vorsprung kann erfindungsgemäß auch ein umlaufender Wulst vorgesehen sein.Preferably, the cap and / or the guide ring made of plastic by injection molding are simple and inexpensive. The snap connection can have interlocking first and second snap means, which engage in such a way that the cap and the guide ring are held together with the radial bearing and with the axial bearing as a structural unit. The first snap means may be resiliently deflectable snap-action noses. The second snap means may be formed by projections and / or recesses, wherein the snap lugs engage behind the projections and / or snap into the recesses. As a projection can be provided according to the invention, a circumferential bead.
Erfindungsgemäße Weiterbildungen sind den Ansprüchen zu entnehmen.Developments according to the invention can be found in the claims.
Die Erfindung ist anhand eines in einer einzigen Figur abgebildeten Ausführungsbeispieles näher erläutert.The invention is explained in more detail with reference to an embodiment shown in a single figure.
