Beschreibungdescription
Gebiet der ErfindungField of the invention
Die Erfindung betrifft ein Kopfteil einer Federbeinaufhängung, das Kopfteil bestehend aus wenigstens einem elastischen Lager, einem Stützelement, aus einer Führung für eine Kolbenstange eines Stoßdämpfers sowie aus einem Befestigungselement zur fahrzeugseitigen Befestigung des Kopfteils, wobei das elastische Lager aus wenigstens einem gummielastischen Element gebildet ist, die Führung mit dem gummielastischen Element verbunden ist, das Stützelement zumindest ein Federbeinlager an dem gummielastischen Element zumindest stützt, das Stützelement mit dem gummielastischen Element verbunden ist und das Befestigungselement an dem gummielastischen Element fest ist und die Erfindung betrifft weiter eine Federbeinaufhängung mit einem Kopfteil, bei der das Federbeinlager mittels wenigstens eines Dichtelementes abgedichtet ist.The invention relates to a head part of a suspension strut suspension, the head part consisting of at least one elastic bearing, a support element, a guide for a piston rod of a shock absorber and a fastener for vehicle-side attachment of the head part, wherein the elastic bearing is formed from at least one rubber-elastic element, the guide is connected to the rubber-elastic element, the support element at least one strut bearing on the rubber-elastic element at least supports, the support member is connected to the rubber-elastic element and the fastener is fixed to the rubber-elastic element and the invention further relates to a suspension strut with a head part at the strut bearing is sealed by means of at least one sealing element.
Hintergrund der ErfindungBackground of the invention
Das Kopfteil ist ein fahrzeugseitiges Anschlussmittel für die Federbeinaufhängung. Die Federbeinaufhängung wird häufig auch Top-Mount genannt und stützt und hält die Kolbenstange des Stoßdämpfers sowie stützt und führt die Feder des Federbeins zum Fahrzeug hin. Die Feder ist mittels des Federbein- lagers in der Federbeinaufhängung um die Schwenkachse des Federbeinlagers schwenkbar gelagert. Dazu stützt sich die Feder an einem so genannten Federteller oder am Federbeinlager direkt ab. Dabei kann sich die Feder direkt an einer gehäuseartigen Schale abstützen, die aus Kunststoff oder Metall ist oder stützt sich über eine Federaufnahme aus Kunststoff bzw. aus einem Elastomer an dem Gehäuse des Federtellers ab.The head part is a vehicle-side connection means for the suspension strut suspension. The strut suspension is often referred to as a top mount and supports and holds the piston rod of the shock absorber and supports and guides the spring of the shock absorber to the vehicle. The spring is pivotally mounted about the pivot axis of the suspension strut bearing by means of the suspension strut bearing in the suspension strut suspension. For this purpose, the spring is supported directly on a so-called spring plate or strut bearing. In this case, the spring can be supported directly on a box-like shell, which is made of plastic or metal or is supported by a spring retainer made of plastic or of an elastomer on the housing of the spring plate.
Der Federteller nimmt einen Lagerring des Federbeinlagers auf, oder ist alter- nativ Bestandteil des eines Federbeinlagers mit integriertem Federteller, wenn die Feder direkt an dem Federbeinlager abgestützt ist. Der Federteller ist beispielsweise einteilig als Stahlblech- oder Leichtmetallbauteil ausgeführt bzw. ist zwei oder mehrteilig gehäuseartig ausgelegt und liegt am Federbeinlager an.The spring retainer receives a bearing ring of the strut mount, or is alternatively part of a suspension strut bearing with integrated spring plate, when the spring is supported directly on the suspension strut bearing. The spring plate is for example made in one piece as a sheet steel or light metal component or is two or more parts designed like a box and is located on the strut bearing.
Stöße und Schwingungen aus dem Fahrbetrieb werden von dem elastischen Lager gedämpft oder vollständig absorbiert. Das elastische Lager ist zumeist ein Gummi-Metall-Lager zur Aufnahme beliebig gerichteter Kräfte und beliebig angreifender Momente, das wenigstens ein gummielastisches Element in Form eines elastischen Blockes aus Gummi, aus anderen Elastomeren bzw. aus gummielastischen Werkstoffen aufweist.Impacts and vibrations from driving are damped or completely absorbed by the elastic bearing. The elastic bearing is usually a rubber-metal bearing for receiving arbitrarily directed forces and arbitrarily attacking moments, which has at least one rubber-elastic element in the form of an elastic block made of rubber, other elastomers or rubber-elastic materials.
Die Stoßdämpferführung und die napf- oder tellerartigen Befestigungselemente sowie die tellerartigen oder napfartig ausgebildeten Stützelemente sind zumindest an dem gummielastischen Element abgestützt, aber zumeist unlösbar aber auch lösbar mit diesem verbunden. Mittels der Stoßdämpferführung ist die Kolbenstange an dem elastischen Lager fest, mittels der oder des Befestigungs- elemente(s) ist das Kopfteil zum Fahrzeug hin befestigt oder abgestützt, und mittels der oder des Stützelemente(s) ist das Federbeinlager an dem/den gummielastischen Element(en) abgestützt. Dabei ist das Stützelement oft selbst Teil des Federbeinlagers.The shock absorber guide and the cup-like or plate-like fastening elements and the plate-like or cup-shaped support elements are supported at least on the rubber-elastic element, but mostly inseparable but also releasably connected thereto. By means of the shock absorber guide, the piston rod is fixed to the elastic bearing, by means of the or the fastening element (s), the head part is fastened or supported towards the vehicle, and by means of the or the support elements (s) is the suspension strut bearing on the / the rubber-elastic element supported. The support element is often itself part of the suspension strut bearing.
Das Federbeinlager ist in der Regel ein Wälzlager oder ist ein Gleitlager und von seiner Wirkrichtung her weitestgehend axial wirkend. Die axialen Komponenten aus Stützkraftangriffen, die sich aus einem Kraftwinkel um die 15° und auch größer ergeben, werden weitestgehend in dem Federbeinlager axial abgestützt. Die axiale Richtung ist die Richtung, die gleichgerichtet mit der Schwenkachse des Federbeinlagers sind. Die Funktion des Federbeinlagers ist über lange Zeit nur abgesichert, wenn dieses vor Schmutz aus der Umgebung der Federbeinaufhängung geschützt ist. Da die Federbeinaufhängung oft durch Umwelteinflüsse, wie Spritzwasser- und Schlamm stark belastet ist, ist die Abdichtung der Federbeinlager problema- tisch. Funktionsfähige Dichtungen sind hinsichtlich Funktion, Gestalt und Vielzahl der Teile sehr komplex und kompliziert, deshalb teuer und beanspruchen viel Platz. Da die Dichtungen hinsichtlich ihrer Funktion dem Federbeinlager zur Umgebung hin vorgeschaltet sind, ist der Durchmesser des Kopfteils und damit der Federbeinaufhängung relativ groß.The suspension strut bearing is usually a rolling bearing or is a sliding bearing and largely effective from its direction of action forth axially. The axial components of Stützkraftangriffen, resulting from a force angle around 15 ° and also larger, are largely supported axially in the strut bearing. The axial direction is the direction that is rectified with the pivot axis of the strut mount. The function of the suspension strut bearing is only secured for a long time, if this is protected from dirt from the environment of the strut suspension. Since the strut suspension is often heavily contaminated by environmental influences, such as spray water and mud, the sealing of the suspension strut bearing is problematic. Functional seals are very complex and complicated in terms of function, shape and variety of parts, therefore expensive and take up much space. Since the seals with respect to their function are preceded by the strut bearing to the environment, the diameter of the head part and thus the suspension strut suspension is relatively large.
DE 199 21 695 A1 zeigt eine Federbeinaufhängung, bei der ein komplex gestalteter Lagerring des Federbeinlagers den Federteller umgreift und mit einer Dichtlippe versehen ist. Die an dem Federteller anliegende Dichtung dichtet zusammen mit einer Spaltdichtung zwischen Lagerring und Federteller. Eine derartige Dichtung beansprucht radial viel Bauraum, der für Federbeinaufhängungen moderner kompakter Radaufhängungen nicht in jedem Fall zur Verfügung steht. Die Herstellungskosten für einen derartig gestalteten Außenring sind relativ hoch.DE 199 21 695 A1 shows a suspension strut suspension in which a complex designed bearing ring of the spring strut bearing surrounds the spring plate and is provided with a sealing lip. The seal applied to the spring plate seals together with a gap seal between bearing ring and spring plate. Such a seal requires a lot of space radially, which is not always available for strut suspensions modern compact suspension. The manufacturing cost of such a shaped outer ring are relatively high.
Zusammenfassung der ErfindungSummary of the invention
Die Aufgabe der Erfindung ist es daher eine einfache, kostengünstige und Bauraum sparende Federbeinaufhängung zu schaffen.The object of the invention is therefore to provide a simple, inexpensive and space-saving strut suspension.
Diese Aufgabe ist nach dem Gegenstand des Anspruches 1 und weiterer abhängiger Ansprüche gelöst. Das gummielastische Element des elastischen Lagers an dem Kopfteil weist wenigstens ein Dichtelement auf. Das Dichtelement ist ringförmig ausgebildet und an dem gummielastischen Element fest.This object is solved according to the subject matter of claim 1 and further dependent claims. The rubber-elastic element of the elastic bearing on the head part has at least one sealing element. The sealing element is annular and fixed to the rubber-elastic element.
Mit einem weiteren unabhängigen Anspruch ist vorgesehen, dass die Federbeinaufhängung wenigstens eine Dichtung aus dem Dichtelement an dem Kopfteil und aus einer Dichtfläche an dem Federteller aufweist. In diesem Fall ist die Dichtung beispielsweise an dem Stützelement oder an dem Befestigungsele- ment oder vorzugsweise an dem elastischen Lager, bevorzugt an dem gummielastischen Element, ausgebildet.With a further independent claim it is provided that the suspension strut suspension has at least one seal from the sealing element on the head part and from a sealing surface on the spring plate. In this case, the seal is, for example, on the support element or on the fastening element ment or preferably on the elastic bearing, preferably formed on the rubber-elastic element.
Eine derartige Dichtung ist einfach und ohne zusätzlichen Aufwand in die Ferti- gung beispielsweise des elastischen Lagers integrierbar. Die Anzahl der Teile und damit z.B. der Aufwand für Lagerung und Logistik ist reduziert. Für die Dichtung wird kein gesonderter Bauraum beansprucht, da diese in das Kopfteil integriert ist. Zusätzliche Kosten für das fertigungstechnische Anbringen eines entsprechenden Dichtelements an ein Blechteil entfallen.Such a seal can be integrated easily and without additional effort into the production of, for example, the elastic bearing. The number of parts and thus e.g. the storage and logistics costs are reduced. For the seal no separate space is claimed because it is integrated into the headboard. Additional costs for the manufacturing technology attaching a corresponding sealing element to a sheet metal part account.
Das Dichtelement ist mit dem gummielastischen Element lösbar oder vorzugsweise unlösbar verbunden. Das Dichtelement ist aus anderem Material als das des gummielastischen Elements hergestellt und dann mit dem Material des gummielastischen Elements verbunden. Alternativ ist das Dichtelement vor- zugsweise aus dem Material des gummielastischen Elements und, wie eine Ausgestaltung der Erfindung vorsieht, mit diesem einteilig ausgebildet. Es ist zum Beispiel vorgesehen, das Dichtelement beim Herstellen des elastischen Blocks zeitgleich anzuspritzen oder anzupressen. Insbesondere dann, wenn das Dichtelement oder die Dichtelemente einteilig mit dem Material des gummi- elastischen Elements ausgebildet sind, entstehen nur geringe oder keine Mehrkosten für die DichtungThe sealing element is releasably or preferably permanently connected to the rubber-elastic element. The sealing element is made of a different material than that of the rubber-elastic element and then connected to the material of the rubber-elastic element. Alternatively, the sealing element is preferably made of the material of the rubber-elastic element and, as an embodiment of the invention, integrally formed therewith. For example, it is intended to simultaneously inject or press the sealing element during production of the elastic block. In particular, when the sealing element or the sealing elements are formed integrally with the material of the rubber-elastic element, little or no additional costs for the seal arise
Als Materialien für die einteilige Gestalt des gummielastischen Elements und des Dichtelements sind alle Materialien, deren Verbundwerkstoffe oder deren Mixturen vorgesehen, die geeignet sind dauerhaft zu Dämpfen, elastisch nachzugeben und deren Charakteristik auch für Dichtungen geeignet ist.As materials for the one-piece design of the rubber-elastic element and the sealing element, all materials, their composites or mixtures thereof are provided which are suitable for permanently damping, elastically yielding and whose characteristic is also suitable for seals.
Das Dichtelement sind zum Beispiel Vorsprünge, Erhebungen und Vertiefungen für Labyrinth bzw. Spaltdichtungen. Eine Ausgestaltung der Erfindung sieht vor, dass das Dichtelement mindestens eine Dichtlippe ist, wobei die Dichtlippe ringförmig radial beabstandet um die Schwenkachse des Federbeinlagers verläuft und, bezogen auf die Schwenkachse, zumindest in mit der Ausrichtung der Schwenkachse gleichgerichtete axiale Richtung aus dem gummielastischen Element hervorsteht. Die Dichtlippe weist die charakteristischen Gestaltungsmerkmale aller üblichen bekannten Dichtlippen auf und ist bevorzugt an den elastischen Block angespritzt oder an diesem auf andere Art zeitgleich mit seiner Herstellung angeformt.The sealing element are, for example, projections, elevations and depressions for labyrinth or gap seals. An embodiment of the invention provides that the sealing element is at least one sealing lip, wherein the sealing lip annularly radially spaced around the pivot axis of the strut bearing and, based on the pivot axis, at least in the alignment of the pivot axis rectified axial direction of the rubber-elastic Element protrudes. The sealing lip has the characteristic design features of all conventional known sealing lips and is preferably molded onto the elastic block or formed on this other way at the same time with its production.
Die Dichtung selbst ist eine Spaltdichtung, bei der sich das Dichtelement und die Dichtfläche an einem Dichtspalt einander gegenüberliegen oder dichtet ab, indem das Dichtelement dichtend an der Dichtfläche anliegt. Je nach Gestaltung der Dichtungsanordnung sind sowohl in axiale Richtung oder in radiale Richtung zur Schwenkachse bzw. in beide Richtungen wirkende Dichtungswirkungen zu erzielen.The seal itself is a gap seal, in which the sealing element and the sealing surface on a sealing gap face each other or seals by the sealing element sealingly abuts the sealing surface. Depending on the design of the seal arrangement, sealing effects acting both in the axial direction or in the radial direction relative to the pivot axis or in both directions can be achieved.
Das Dichtelement schließt die Trennstelle der Federbeinaufhängung, an der der Federteller relativ zum festen Kopfteil schwenkbeweglich ist, dichtend ab und verläuft deshalb radial zur Schwenkachse betrachtet außen liegend mit gleich bleibenden radialen Abstand zur Schwenkachse des Federbeinlagers. Das Federbeinlager liegt radial näher an der Schwenkachse als die Dichtung.The sealing element closes the separation point of the suspension strut, on which the spring plate is pivotally movable relative to the fixed head part, sealingly and therefore extends radially to the pivot axis considered outside lying with the same radial distance from the pivot axis of the suspension strut bearing. The strut bearing is radially closer to the pivot axis than the seal.
Detaillierte Beschreibung der ZeichnungDetailed description of the drawing
Die Erfindung wird in Figur 1 und Figur 2 nachfolgend anhand jeweils eines Teilschnitts eines Ausführungsbeispiels einer Federbeinaufhängung näher erläutert.The invention will be explained in more detail in Figure 1 and Figure 2 with reference to a partial section of an embodiment of a strut suspension.
Figur 1 zeigt eine Federbeinaufhängung 1 mit einem Kopfteil 2, einem Stützelement 20 und einem Federbeinlager 3. Das Kopfteil 2 weist ein elastisches Lager 4 in Form eines Gummimetall-Lagers auf, mit dem die Federbeinaufhängung 1 fahrzeugsseitig anzubinden ist. Wesentlicher Bestandteil des elastischen Lagers 4 ist zumindest ein gummielastisches Element 30 in Form eines ein- oder mehrteiligen gummielastischen Blockes 5 zur chassisseitigen elastischen Lagerung eines nicht dargestellten Stoßdämpfers sowie zur chassisseitigen Abstützung des Federbeinlagers 3. Das Kopfteil 2 ist weiterhin mit einer Kolbenstangenaufnahme 6 aus Blech versehen, die mit dem gummielastischen Block 5 mittels zum Beispiel Vulkanisieren oder alternativ Umsphtzen fest verbunden ist. Die Kolbenstangenaufnahme 6 weist eine hülsenförmige Führung 7 für eine nur angedeutet dargestellte KoI- benstange 8 des Stoßdämpfers auf. Die Kolbenstangenaufnahme ist alternativ aus Leichtmetallen oder deren Legierungen oder aus Kunststoff hergestellt. Es gibt auch Anwendungen, in denen die Kolbenstangenaufnahme nicht fest mit dem gummielastischen Block verbunden ist, sondern als separates Teil nur an dem Block abgestützt ist.1 shows a suspension strut 1 with a head part 2, a support member 20 and a suspension strut bearing 3. The head part 2 has an elastic bearing 4 in the form of a rubber-metal bearing with which the suspension strut 1 is to be connected on the vehicle side. An essential part of the elastic bearing 4 is at least one rubber-elastic element 30 in the form of a one-piece or multi-part rubber-elastic block 5 for the chassis-side elastic mounting of a shock absorber, not shown, as well as the chassis-side support of the strut bearing. 3 The head part 2 is further provided with a piston rod receptacle 6 made of sheet metal, which is fixedly connected to the rubber-elastic block 5 by means of, for example, vulcanization or alternatively Umsphtzen. The piston rod receptacle 6 has a sleeve-shaped guide 7 for a piston rod 8 of the shock absorber which is only indicated. The piston rod receptacle is alternatively made of light metals or their alloys or of plastic. There are also applications in which the piston rod receptacle is not fixedly connected to the rubber-elastic block, but is supported as a separate part only on the block.
Der gummielastischer Block 5 kann wahlweise auch mit Hohlkammern versehen sein und verbindet die Kolbenstangenaufnahme 6 mit einem Befestigungselement 10 in diesem Fall in Form eines tellerartigen Befestigungsbleches 9 zur fahrzeugseitigen Befestigung der Federbeinaufhängung 1. Das Befestigungs- element 10 und der gummielastischer Block 5 sind durch Vulkanisieren, Kleben oder umsphtzen unlösbar miteinander verbunden. Denkbar ist auch, dass das Befestigungselement und der gummielastische Block lösbar miteinander verbunden sind.The rubber-elastic block 5 can optionally also be provided with hollow chambers and connects the piston rod receptacle 6 with a fastening element 10 in this case in the form of a plate-like mounting plate 9 for securing the suspension strut 1 on the vehicle. The fastening element 10 and the rubber-elastic block 5 are made by vulcanization, Sticking or umsphtzen inextricably linked. It is also conceivable that the fastening element and the rubber-elastic block are detachably connected to each other.
Die Kolbenstangenaufnahme 6 setzt sich bei diesem Ausführungsbeispiel einteilig in dem Stützelement 20 in Form eines kragenartigen Stützabschnittes 11 fort. An dem Stützabschnitt 11 ist ein Lagerring 12 des Federbeinlagers 3 abgestützt. Das Federbeinlager 3 ist ein Wälzlager aus Kugeln 13 und aus Lagerringen 12. Denkbar ist, dass das Federbeinlager 3 ein Gleitlager ist. An den Lager- ringen 12 und 15 sind die Laufbahnen 14 der Kugeln 13 ausgebildet. Denkbar ist auch, dass die Laufbahn 14 nicht in dem oberen Lagerring 12 sondern direkt in dem Stützabschnitt 11 ausgebildet ist und der Lagerring somit entfällt.The piston rod receptacle 6 is in this embodiment in one piece in the support member 20 in the form of a collar-like support portion 11 continues. On the support portion 11, a bearing ring 12 of the strut bearing 3 is supported. The strut bearing 3 is a rolling bearing of balls 13 and bearing rings 12. It is conceivable that the suspension strut bearing 3 is a sliding bearing. On the bearing rings 12 and 15, the raceways 14 of the balls 13 are formed. It is also conceivable that the raceway 14 is not formed in the upper bearing ring 12 but directly in the support portion 11 and thus eliminates the bearing ring.
Der untere Lagerring 15 ist in dem Gehäuse 16a des zweiteilig aus dem Ge- häuse 16a und der Federaufnahme 16b gebildeten unteren Federtellers 16 aufgenommen und seitlich mit Borden 17 und 18 an dem Federteller 16 geführt. Die Federaufnahme 16b ist ein Zusatzelement, mit dem weiter Schwingungen gedämpft sind. Es gibt auch Anwendungen ohne dieses zusätzliche Dämp- fungselement. An der wahlweise aus Kunststoff, aus Elastomer(en) oder aus Metall gebildeten Federaufnahme 16b liegt das obere Ende 43 einer nicht weiter dargestellten Schraubenfeder an.The lower bearing ring 15 is received in the housing 16 a of the two-part formed from the housing 16 a and the spring seat 16 b lower spring plate 16 and guided laterally with ribs 17 and 18 on the spring plate 16. The spring receptacle 16b is an additional element with which further vibrations are damped. There are also applications without this additional damping fung element. On the optionally made of plastic, elastomer (s) or metal spring retainer 16b is the upper end 43 of a coil spring, not shown.
Der Federteller 16, der auch einteilig ausgebildet sein kann, ist mittels der Schnappverbindung 19 in das Kopfteil 2 eingehakt, so dass die Federbeinaufhängung 1 eine transportsichere Einheit aus dem Kopfteil 2, aus dem Federbeinlager 3 und zumindest aus dem Federteller 16 ist.The spring plate 16, which may also be formed in one piece, is hooked by means of the snap connection 19 in the head part 2, so that the suspension strut 1 is a transport-safe unit from the head part 2, from the suspension strut bearing 3 and at least from the spring plate 16.
Das Federbeinlager 3 ist gegen die Umgebung mittels einer Labyrinthdichtung 21 und einer Dichtung 22 in Form einer Lippendichtung abgedichtet. Die Labyrinthdichtung 21 ist durch ineinander greifende Strukturen des Federtellers 16 und einer Einlage 23 des Kopfteils 2 gebildet. Die Einlage 23 ist aus Kunststoff wahlweise aus Metall oder Elastomer. Die Dichtung 22 ist der Labyrinthdichtung 21 hinsichtlich der Schutzwirkung gegen Umgebungseinflüsse vorgeschaltet und weist als Dichtelement 40 wenigstens eine Dichtlippe 24 auf. Die Dichtlippe 24 ist einteilig mit dem gummielastischen Block 5 ausgebildet und geht von dem Kopfteil 2 in Richtung des Federtellers 16 ab, verläuft um die Schwenkachse 44 und liegt leicht vorgespannt an einer Dichtfläche 25 des Gehäuses 16a dichtend an. Alternativ ist zwischen der Dichtlippe 24 und der Dichtfläche 25 ein Spalt zur Bildung einer Spaltdichtung ausgebildet. Die Dichtlippe 24 und der Bord 18 schließen eine Ringkammer 26 zwischen sich ein, die zwecks zusätzlicher Dichtwirkung wahlweise mit Fett befüllt sein kann.The suspension strut bearing 3 is sealed against the environment by means of a labyrinth seal 21 and a seal 22 in the form of a lip seal. The labyrinth seal 21 is formed by interlocking structures of the spring plate 16 and an insert 23 of the head part 2. The insert 23 is made of plastic optionally of metal or elastomer. The seal 22 is connected upstream of the labyrinth seal 21 with regard to the protective effect against environmental influences and has at least one sealing lip 24 as a sealing element 40. The sealing lip 24 is integrally formed with the rubber-elastic block 5 and starts from the head part 2 in the direction of the spring plate 16, extends around the pivot axis 44 and is slightly biased to a sealing surface 25 of the housing 16 a sealingly. Alternatively, a gap for forming a gap seal is formed between the sealing lip 24 and the sealing surface 25. The sealing lip 24 and the board 18 include an annular chamber 26 between them, which may optionally be filled with grease for additional sealing effect.
Figur 2 zeigt eine Federbeinaufhängung 27 mit einem Kopfteil 28, mit einem Stützelement 20 und mit einem Federbeinlager 3. Das Kopfteil 28 weist ein e- lastisches Lager 35 in Form eines Gummimetall-Lagers auf, mit dem Federbeinaufhängung 27 fahrzeugsseitig abgestützt ist. Wesentlicher Bestandteil des elastischen Lagers 35 ist zumindest ein ein- oder mehrteiliges gummielasti- sches Element 30 in Form eines oder mehrerer gummielastischer Blöcke 36 zur chassisseitigen elastischen Lagerung eines nicht dargestellten Stoßdämpfers sowie zur chassisseitigen Abstützung des Federbeinlagers 3. Das Kopfteil 28 ist weiterhin mit einer Kolbenstangenaufnahme 37 aus Blech oder anderen Werkstoffen und mit einem Stützelement 20 in Form eines napfartig ausgebildeten und gelochten Stützringes 38 aus Blech und mit dem Befestigungselement 10 aus Blech versehen. Diese Bauteile aus Blech sind mit dem gummielastischer Block 36 mittels zum Beispiel Vulkanisieren, Kleben oder umspritzen in diesem Fall unlösbar miteinander fest verbunden, kann aber auch lösbar mit diesem verbunden oder nur eingelegt sein. Die Kolbenstangenaufnahme 37 ist zumindest eine hülsenförmige Führung 7 für eine nur angedeutet dargestellte Kolbenstange 8 des Stoßdämpfers.Figure 2 shows a strut mount 27 with a head part 28, with a support member 20 and a strut bearing 3. The head part 28 has an elastic bearing 35 in the form of a rubber-metal bearing, is supported on the vehicle side with the strut mount 27. An essential component of the elastic bearing 35 is at least one single- or multi-part rubber-elastic element 30 in the form of one or more elastomeric blocks 36 for the chassis-side elastic mounting of a shock absorber, not shown, as well as for the chassis-side support of the suspension strut bearing 3. The head part 28 is further provided with a piston rod receptacle 37 made of sheet metal or other materials and with a support member 20 in the form of a cup-shaped and perforated support ring 38 made of sheet metal and with the fastening element 10 made of sheet metal. These components made of sheet metal with the rubber-elastic block 36 by means such as vulcanization, gluing or encapsulation in this case are permanently connected to each other, but can also be releasably connected to this or just inserted. The piston rod receptacle 37 is at least one sleeve-shaped guide 7 for a piston rod 8 of the shock absorber shown only.
Der gummielastischer Block 36 verbindet die Kolbenstangenaufnahme 37 und den Stützring 38 mit dem in diesem Fall tellerartig aus Blech gebildeten Befestigungselement 10 zur fahrzeugseitigen Befestigung der Federbeinaufhängung 27.The rubber-elastic block 36 connects the piston rod receptacle 37 and the support ring 38 with the plate-like in this case made of sheet metal fastener 10 for vehicle-mounted attachment of the suspension strut 27th
An dem zur Kolbenstangenaufnahme 37 separaten Stützring 38 ist ein Lagerring 12 des Federbeinlagers 3 abgestützt. Das Federbeinlager 3 ist ein Wälzlager aus Kugeln 13 und aus Lagerringen 12. Denkbar ist, dass das Federbeinlager 3 ein Gleitlager ist. An den Lagerringen 12 und 15 sind die Laufbahnen 14 der Kugeln 13 ausgebildet. Denkbar ist auch, dass die Laufbahn 14 direkt in dem Stützring 38 ausgebildet ist.At the piston rod receptacle 37 separate support ring 38, a bearing ring 12 of the strut bearing 3 is supported. The strut bearing 3 is a rolling bearing of balls 13 and bearing rings 12. It is conceivable that the suspension strut bearing 3 is a sliding bearing. On the bearing rings 12 and 15, the raceways 14 of the balls 13 are formed. It is also conceivable that the raceway 14 is formed directly in the support ring 38.
Der untere Lagerring 15 ist in dem Gehäuse 29a des zweiteilig aus dem Gehäuse 29a und der Federaufnahme 16b gebildeten unteren Federtellers 29 auf- genommen und seitlich mit Borden 39 und 34 an dem Federteller 29 geführt.The lower bearing ring 15 is accommodated in the housing 29a of the lower spring plate 29 formed in two parts from the housing 29a and the spring receptacle 16b and guided laterally with ribs 39 and 34 on the spring plate 29.
Das Federbeinlager 3 ist gegen die Umgebung mittels einer Spaltdichtung 33 und einer Dichtung 32 in Form einer Lippendichtung abgedichtet. Die Spaltdichtung 33 ist durch einander gegenüberliegende Bereiche des Stützabschnitts 38 und des Bordes 39 mit einem Ringspalt 41 zwischen sich gebildet. Die Dichtung 32 ist der Spaltdichtung 33 hinsichtlich der Schutzwirkung gegen Umgebungseinflüsse vorgeschaltet und weist als Dichtelement 40 wenigstens zwei Dichtlippen 31 auf. Die Dichtlippen 31 sind einteilig mit dem gummielastischen Block 36 ausgebildet und stehen von dem Kopfteil 28 in Richtung des Federtellers 29 ab, verlaufen um das Federbeinlager 3 und liegen an einer Dichtfläche 25 des Gehäuses 29a dichtend an. Alternativ ist zwischen wenigstens einer der Dichtlippen 31 und der Dichtfläche 25 ein Spalt zur Bildung einer Spaltdichtung ausgebildet. Die dem Federbeinlager 3 am nächsten liegende der Dichtlippen 31 und der Bord 18 schließen eine Ringkammer 42 zwischen sich ein, die zwecks zusätzlicher Dichtwirkung wahlweise mit Fett befüllt sein kann. The suspension strut bearing 3 is sealed against the environment by means of a gap seal 33 and a seal 32 in the form of a lip seal. The gap seal 33 is formed by opposing portions of the support portion 38 and the board 39 with an annular gap 41 between them.
