Description
Gebiet der ErfindungField of the invention
Die Erfindung betrifft eine Federbeingleitlageranordnung mit einem Federbeingleitlager zur Aufnahme zumindest von axial gerichteten Kräften, wobei die axialen Kräfte mit der Mittelachse gleichgerichtet sind, und wobei in der Federbeingleitlageranordnung:
- – das Federbeingleitlager aus mindestens einer unteren Lagerschale und aus wenigstens einem Gleitelement gebildet ist,
- – das Gleitelement axial zwischen Gleitflächen abgestützt ist, wobei die Gleitflächen sich axial einander gegenüberliegen und mit radialem Abstand zur Mittelachse ausgebildet sind, wobei mindestens eine der Gleitflächen an der unteren Lagerschale ausgebildet ist,
- – die untere Lagerschale über eine nichtmetallische Federauflage zumindest an einem Federende einer oberen Windung einer Schraubenfeder wenigstens axial abgestützt ist,
- – die obere Windung mit Federende mit radialem Abstand zur Mittelachse so an dem Federbeingleitlager anliegend ausgerichtet ist, dass die in dem Federbeinlager abgestützten axialen Kräfte, von der oberen Windung aus direkt mit dem gleichem radialen Abstand axial in das Gleitelement und die Gleitflächen hineingeleitet werden.
- The spring sliding bearing is formed from at least one lower bearing shell and from at least one sliding element,
- The sliding element is supported axially between sliding surfaces, wherein the sliding surfaces are axially opposite one another and are formed at a radial distance from the central axis, wherein at least one of the sliding surfaces is formed on the lower bearing shell,
- The lower bearing shell is at least axially supported by a non-metallic spring support at least at one spring end of an upper turn of a helical spring,
- - The upper turn with spring end with radial distance to the central axis is aligned with the Federbeingleitlager that the supported in the strut bearing axial forces, are led in from the upper turn directly with the same radial distance axially into the sliding member and the sliding surfaces.
Hintergrund der ErfindungBackground of the invention
Üblicherweise sind die unteren Lagerschalen von Federbeingleitlagern an einem Federteller aus Blech axial abgestützt. An dem Federteller liegt die letzte obere Windung einer Schraubenfeder eines McPherson Federbeins an. Der Durchmesser, d. h. der radiale Abstand zur Mittelachse also zur Schwenkachse des Federbeinlagers, mit dem die obere Windung bzw. das Federende an der Federauflage des Federtellers anliegt, ist in der Regel größer als der radiale Durchmesser des Federbeingleitlagers an dem Gleitelement und den Gleitflächen. Die axial gerichteten Kräfte werden deshalb radialen Abständen zur Mittelachse in die Federauflage eingeleitet, die größer sind als die Abstände, mit denen die gleichen axialen Kräfte von Gleitfläche zu Gleitfläche durch das Federbeinlager geleitet werden.Usually, the lower bearings of Federbeingleitlagern be axially supported on a spring plate made of sheet metal. On the spring plate is the last upper turn of a coil spring of a McPherson shock absorber. The diameter, d. H. the radial distance to the central axis that is to the pivot axis of the strut bearing, with which the upper turn or the spring end rests against the spring seat of the spring plate is usually greater than the radial diameter of the Federbeingleitlagers on the sliding element and the sliding surfaces. The axially directed forces are therefore introduced radial distances from the central axis in the spring rest, which are greater than the distances at which the same axial forces are passed from sliding surface to sliding surface through the strut mount.
Die Erfindung betrifft jedoch eine Gattung von Federbeinlagern, an denen die Federauflage axial unterhalb der Gleitscheibe an der Federauflage so angreifen, dass die Kräfte über die Federauflage axial direkt gerichtet mit gleichen radialen Abständen zur Mittelachse durch die untere Lagerschale zur unteren Reibfläche und von dort zur oberen Gleitfläche beispielsweise an einer oberen Lagerschale weitergeleitet werden.However, the invention relates to a genus of strut bearings on which the spring support axially below the sliding disk on the spring support so attack that the forces on the spring support axially directly with the same radial distances from the central axis through the lower bearing shell to the lower friction surface and from there to the upper Sliding example be forwarded to an upper bearing shell.
Derartige Federbeingleitlager sind in
Die Gründe für eine derartige Anordnung sind verschiedene. Einer der Gründe ist in der einfachen Austauschbarkeit von Federbeinwälzlagern durch die in der Regel kostengünstig herzustellenden Federbeingleitlager zu sehen. Ein anderer Grund ist die Einsparung von Bauraum.The reasons for such an arrangement are different. One of the reasons can be seen in the simple interchangeability of strut roller bearings by the usually produced at low spring clip bearings. Another reason is the saving of space.
Federbeingleitlager sind im Wesentlichen aus nichtmetallische Werkstoffen gebildet. Das betrifft die untere und die obere Lagerschale, ggf. eine separate Federauflage und die Gleitelemente. Die Gleitelemente sind in der Regel Gleitscheiben oder Gleitringe aus verschiedensten Werkstoffen. Zumindest die den Gleitflächen zugewandten Oberflächen der Gleitelemente sind relativ weich. Die separate Federauflage ist aus gummielastischen Werkstoff oder aus einem Elastomer bzw. einem Kautschuk. Ansonsten ist die Federauflage an der unteren Lagerschale ausgebildet. Die Schraubenfeder ist aus Stahl. Derartige Federbeinlager sind deshalb verglichen zum harten Werkstoff der Schraubenfeder weich.Federbeingleitlager are essentially formed of non-metallic materials. This concerns the lower and the upper bearing shell, possibly a separate spring support and the sliding elements. The sliding elements are usually sliding or sliding rings made of various materials. At least the sliding surfaces facing surfaces of the sliding elements are relatively soft. The separate spring support is made of rubber-elastic material or of an elastomer or a rubber. Otherwise, the spring seat is formed on the lower bearing shell. The coil spring is made of steel. Such strut bearings are therefore soft compared to the hard material of the coil spring.
Durch die Gestalt des Federendes ist der Kontakt der Schraubenfeder an der Federauflage nicht gleichmäßig. Konturen des harten Federendes verformen die Kunststoffe und bilden sich durch die untere Lagerschale hindurch als ungewollte Erhöhungen oder Vertiefungen an den Gleitflächen ab. Die Oberfläche oder gar das gesamte Gleitelement verformt sich dementsprechend mit. Das kann am axial belasteten Federbeingleitlager zu formschlüssig miteinander kooperierenden Deformationen an den Gleitflächen und dem Gleitelement führen. Bestimmungsgemäße Relativschwenkbewegungen der Gleitflächen zum Gleitelement werden an diesen Deformationen gehemmt. Das führt an diesen Stellen zu erhöhtem Verschleiß im Federbeingleitlager, insbesondere an dem Gleitelement.Due to the shape of the spring end, the contact of the coil spring on the spring support is not uniform. Contours of the hard spring end deform the plastics and form through the lower bearing shell as unwanted elevations or depressions on the sliding surfaces. The surface or even the entire sliding deformed accordingly with. This can lead to positively loaded cooperating with each other deformations on the sliding surfaces and the sliding element on axially loaded Federbeingleitlager. Intended Relativschwenkbewegungen the sliding surfaces to the sliding element are inhibited at these deformations. This leads at these points to increased wear in Federbeingleitlager, in particular on the sliding element.
Zusammenfassung der Erfindung Summary of the invention
Die Aufgabe der Erfindung ist es daher, eine Federbeingleitlageranordnung mit einem Federbeingleitlager zu schaffen, mit der die zuvor genannten Nachteile vermieden werden.The object of the invention is therefore to provide a Federbeingleitlageranordnung with a Federbeingleitlager, with which the aforementioned disadvantages are avoided.
Die Aufgabe ist mit dem Gegenstand des Anspruchs 1 gelöst.The object is solved with the subject matter of claim 1.
Die Federauflage ist erfindungsgemäß mit wenigsten einer metallischen Verstärkung verstärkt. Die Verstärkung und die Federauflage untrennbar miteinander verbunden sind.The spring support is reinforced according to the invention with at least one metallic reinforcement. The reinforcement and the spring rest are inseparable.
Die Federauflage ist an der unteren Lagerschale ausgebildet, und beispielsweise eine Nut deren Tiefe zur Anlage mit dem Federende hin abnimmt. Die Verstärkung ist entweder unmittelbar an der unteren Lagerschale als Federauflage ausgebildet oder alternativ als Gleitfläche unterhalb des Gleitelement und beispielsweise an der Lagerschale mit einer Schnappverbindung befestigt. Alternativ ist die Verstärkung oder sind mehrere Verstärkungen in das untere Gehäuse integriert. In diesem Fall kann die Verstärkung von dem Kunststoff umspritzt sein.The spring seat is formed on the lower bearing shell, and, for example, a groove whose depth decreases to rest with the spring end. The reinforcement is either formed directly on the lower bearing shell as a spring rest or alternatively as a sliding surface below the slider and, for example, attached to the bearing shell with a snap connection. Alternatively, the reinforcement or multiple reinforcements are integrated into the lower housing. In this case, the reinforcement may be overmoulded by the plastic.
Die Verstärkung ist allgemein härter als der Kunststoff, aus dem die untere Lagerschale ist. Die Verstärkung ist beispielsweise eine Scheibe aus Blech oder ein Ring, der um die Mittelachse umläuft. Die ein- oder mehrteilige Verstärkung ist beispielsweise eine Lochscheibe, eine Winkelscheibe, sind alternativ z. B. Plättchen, Gitter und Netze, vorzugsweise aus Metall.The reinforcement is generally harder than the plastic from which the lower bearing shell is made. The reinforcement is, for example, a disc made of sheet metal or a ring which rotates about the central axis. The one- or multi-part gain is for example a perforated disc, an angle disc, are alternatively z. As platelets, grids and networks, preferably of metal.
