Schraubendruckfederanordnung Helical compression spring arrangement
Die vorliegende Erfindung betrifft eine Schraubendruckfederanordnung mit einer Schraubendruckfeder, die mit mindestens einem axial endständigen Auflageabschnitt auf einer Federunterlage aufliegt, sowie die Verwendung einer solchen Schraubendruckfederanordnung in einem Federbein eines Fahrzeugs. The present invention relates to a helical compression spring assembly with a helical compression spring, which rests with at least one axially terminal support portion on a spring pad, and the use of such a helical compression spring assembly in a strut of a vehicle.
Derartige Schraubendruckfederanordnungen weisen eine Schraubendruckfeder, die aus einem um eine Mittelachse vorzugsweise zylindrisch gewickelten Federdraht gebildet wird, auf, wobei die Schraubendruckfeder an ihren in Längserstreckung befindlichen Enden Anlageflächen zur Anlage an entsprechenden Federunterlagen, auch Federteller genannt, aufweist. Eine solche Schraubendruckfederanordnung ist beispielsweise in der DE 10 2007 003 782 A1 gezeigt. In solcher Weise aufgebaute Schraubendruckfederanordnungen werden insbesondere im Fahrzeugbau im Bereich des Fahrwerks verwendet, wo sie den Aufbau des Fahrzeugs federnd gegenüber den Radführungselementen abstützen. Dabei ist eine Federunterlage radseitig, beispielsweise an einem Dämpferrohr oder einem Fahrwerks- lenker, ausgebildet, während eine aufbauseftige Federunterlage an dem Aufbau des Fahrzeugs gelagert ist. Eine Problemstellung ist dabei, dass die Schraubendruckfeder auch bei maximaler Ausfederung (beispielsweise beim Aufbocken des Fahrzeugs) nicht von den Federunterlagen abhebt und somit aus diesen herausrutscht. Such helical compression spring arrangements have a helical compression spring, which is formed from a preferably coiled around a central axis spring wire, on, wherein the helical compression spring at their ends located in the longitudinal direction bearing surfaces for abutment with corresponding spring pads, also called spring plate has. Such a helical compression spring arrangement is shown for example in DE 10 2007 003 782 A1. Built in such a manner helical compression spring assemblies are used in particular in vehicle construction in the area of the chassis, where they support the structure of the vehicle resiliently relative to the Radführungselementen. In this case, a spring pad is on the wheel side, for example on a damper tube or a chassis handlebar, formed while a aufbauseftige spring pad is mounted on the body of the vehicle. A problem is that the helical compression spring does not lift off the spring pads even at maximum rebound (for example, when jacking up the vehicle) and thus slip out of them.
Aus der DE, 10 2008 046 939 A1 ist bekannt, dass eine gummielastische Federunterlage an eine Endwindung der Schraubenfeder aufvulkanisiert ist. Dies hat jedoch den Nachteil,, dass der Herstellungsprozess sehr aufwändig, ist, da die Federunterlagen mit der Schraubenfeder bei den entsprechenden Temperaturen einem Vulkan isationsvorgang unterzogen werden müssen. ' Zudem kann die Schraubenfeder später nur zusammen , mit den Federunterlagen getauscht werden, wodurch sich die Reparafurkosten erhöhen. Ähnliche Probleme ergeben sich auch bei einer Anordnung gemäß der DE 10 201 1 002 065 A1 , die ein Verkleben der Feder mit den Federunterlagen vorschlägt. From DE , 10 2008 046 939 A1 it is known that a rubber-elastic spring pad is vulcanized to an end turn of the coil spring. However, this has the disadvantage that the manufacturing process is very complex, since the spring documents must be subjected to a vulcanization process with the coil spring at the appropriate temperatures. 'In addition, the coil spring can later only be replaced together with the spring pads, which increases the repair costs. Similar problems also arise in an arrangement according to DE 10 201 1 002 065 A1, which proposes a gluing of the spring with the spring pads.
Aufgabe der vorliegenden Erfindung ist es daher eine Schraubendruckfederanordnung bereitzustellen, bei der die Schraubendruckfeder einfach und zuverlässig gegen ein axiales Abheben aus der Federunterlage gesichert werden kann. Object of the present invention is therefore to provide a helical compression spring arrangement in which the helical compression spring can be easily and reliably secured against axial lifting from the spring pad.
Diese Aufgabe wird durch die Merkmale des Patentanspruchs 1 gelöst. This object is solved by the features of patent claim 1.
In Patentanspruch 6 wird die Verwendung einer erfindungsgemäßen Schraubendruckfederanordnung in einem Federbein eines Fahrzeugs beansprucht. In claim 6, the use of a helical compression spring assembly according to the invention is claimed in a strut of a vehicle.
Eine Schraubendruckfederanordnung hat eine Schraubendruckfeder, die mit mindestens einem axial endständigen Auflageabschnitt auf einer Federunter- lage aufliegt, wobei der Auflageabschnitt Mittel zur Ausbildung eines zumindest axial wirksamen Formschlusses mit korrespondierenden Mitteln der Fe- derunterlage-aufweist, A helical compression spring arrangement has a helical compression spring which rests on a spring support with at least one axially terminal support section, wherein the support section has means for forming an at least axially positive fit with corresponding means of the spring support;
Indem die Schraubendruckfeder in einem axial . endständigen Auflageabschnitt mit einem entsprechenden Teil einer Federwindung auf der korrespondierenden Federunterlage aufliegt und der Auflageabschnitt und die Federunterlage über Mittel formschlüssig miteinander verbunden sind, kann die Schraubendruckfederanordnung schnell gefertigt werden und bietet in extremen Federzuständen Sicherheit gegen ein axiales Abheben von der Federunterlage. Zudem können die Schraubendruckfeder und die Federunterlagen separat getauscht werden, wenn der Formschluss lösbar, ausgebildet ist. Wahlweise kann der Formschluss an einem oder an beiden axialen Enden der Schraubendruckfedern ausgebildet sein. By the helical compression spring in an axial. terminal support portion rests with a corresponding part of a spring coil on the corresponding spring pad and the support portion and the spring pad are positively connected to each other via means, the helical compression spring assembly can be made quickly and provides in extreme spring conditions security against axial lifting of the spring pad. In addition, the helical compression spring and the spring pads be exchanged separately when the positive connection is releasable, is formed. Optionally, the positive connection may be formed on one or both axial ends of the helical compression springs.
In einer bevorzugten Ausführung wird der Formschluss durch ein Verrasten der Mittel des Auflageabschnitts der Schraubendruckfeder mit den korrespondierenden Mitteln der Federunterlage erzeugt. Ein Verrasten bietet die Möglichkeit eines sehr schnellen und einfachen Zusammenbaus. In a preferred embodiment, the positive connection is generated by a locking of the means of the support portion of the helical compression spring with the corresponding means of the spring pad. Locking offers the possibility of a very quick and easy assembly.
In einer bevorzugten Ausführung sind die Mittel des Auflageabschnitts als mindestens eine Rastnase und die Mittel der Federunteriage als zu der mindestens einen Rastnase korrespondierende Rastnuten ausgebildet. Die Rastnase steht vom Auflageabschnitt der Schraubendruckfeder in axialer Richtung ab und ist beispielsweise hakenförmig ausgebildet. Die Rastnut ist eine korrespondierende Aussparung in der Federunterlage, in die die Rastnase formschlüssig eingreifen kann. Neben der axialen Sicherung ist die Schraubendruckfeder damit auch gegen ein Verdrehen gesichert. In a preferred embodiment, the means of the support section are formed as at least one latching lug and the means of Federunteriage as to the at least one latching lug corresponding locking grooves. The detent protrudes from the support portion of the helical compression spring in the axial direction and is formed, for example, hook-shaped. The locking groove is a corresponding recess in the spring pad, in which the latch can engage positively. In addition to the axial securing the helical compression spring is thus secured against rotation.
In einer bevorzugten Ausführung liegt der Auflageabschnitt bei bestimmungsgemäßer Benutzung der Schraubendrückfederanordnung permanent an der Federunterlage auf. Im Gegensatz dazu hat die Schraubendruckfeder einen an den Auflageabschnitt angrenzenden Abwälzabschnitt, der nur bei einer entsprechenden Kompression der Schraubendruckfeder mit der Federunteriage in Berührung kommt. Die Anordnung der Mittel zum Formschluss im Auflageabschnitt hat den Vorteil, dass diese bei der Kompression der Feder nur gering mechanisch belastet werden. In a preferred embodiment, the support section is permanently seated on the spring support when the helical compression spring arrangement is used as intended. In contrast, the helical compression spring has a rolling portion adjacent to the support portion, which comes into contact only with a corresponding compression of the helical compression spring with the Federunteriage. The arrangement of the means for positive engagement in the support section has the advantage that they are only slightly mechanically loaded during the compression of the spring.
In einer bevorzugten Ausführung besteht die Schraubendruckfeder aus einem glasfaserverstärkten Kunststoff (GFK). Eine GFK-Schraubendruckfeder wird aus einer Vielzahl von Glasfaserfäden gewickelt, die mit einem Bindemittel zusammengehalten werden. GFK-Scjiraubendruckfedem sind im Vergleich zu Stahlfedern deutlich leichter und bieten darüber hinaus den Vorteil, PC17EP2014/000552 In a preferred embodiment, the helical compression spring made of a glass fiber reinforced plastic (GRP). A GFK helical compression spring is wound from a variety of glass fiber filaments that are held together with a binder. GRP Scjiraubendruckfedem are compared to steel springs significantly lighter and also have the advantage PC17EP2014 / 000552
4 dass die Mittel zur Ausbildung des Formschlusses mit der Federunteriage, insbesondere die Rastnasen, sehr einfach beim Herstellungsprozess mit angeformt werden können.  4 that the means for forming the positive connection with the Federunteriage, in particular the locking lugs, can be easily formed in the manufacturing process with.
Bei der Verwendung einer erfindungsgemäßen Schraubendruckfederanord- nung in einem Federbein eines Fahrzeugs ist eine radseitige Federunterlage an einem Dämpferrohr oder einem Fahrwerkslenker anzuordnen, während eine aufbauseitige Federunterlage an einem Aufbau des Fahrzeugs anzuordnen ist. Die Schraubendruckfeder stützt somit den Aufbau gegenüber den Radführungselementen ab. Es wäre bei diesem Anwendungsfall ausreichend, wenn die aufbauseitige Federunterlage und der entsprechende Auflageabschnitt die Mittel zum Formschluss aufweisen. Das auf der Schraubendruckfeder lastende Gewicht des Aufbaus komprimiert diese im Ruhezustand, so dass ein Teil der Federwindungen den permanent auf der entsprechenden Federunteriage aufliegenden Auflageabschnitt bildet. Der Abwälzabschnitt ist der Teil der Schraubendruckfeder, der sich bei einer Laständerung, beispielsweise durch die Anregung einer unebenen Straße, zeitweise zusätzlich zu dem Auflageabschnitt an der Federunterlage anlegt. When using a helical compression spring arrangement according to the invention in a spring strut of a vehicle, a wheel-side spring pad is to be arranged on a damper tube or a chassis link, while a body-side spring pad is to be arranged on a body of the vehicle. The helical compression spring thus supports the structure from the wheel guide elements. It would be sufficient in this application, when the body-side spring pad and the corresponding support section have the means for positive engagement. The weight of the superstructure on the helical compression spring compresses it in the quiescent state, so that a part of the spring coils forms the abutment portion permanently resting on the corresponding spring washer. The Abwälzabschnitt is the part of the helical compression spring, which applies at a load change, for example, by the excitation of an uneven road, temporarily in addition to the support portion of the spring pad.
Weitere Einzelheiten und Vorteile der Erfindung ergeben sich aus der nachstehenden Beschreibung eines bevorzugten Ausführungsbeispiels unter Bezugnahme auf die Zeichnungen. Further details and advantages of the invention will become apparent from the following description of a preferred embodiment with reference to the drawings.
