Kraftaufnehmende Verbindung und Verfahren zur Herstellung einer solchen Verbindung Technisches Gebiet  Force-absorbing connection and method for producing such a connection Technical field
[0001] Die vorliegende Erfindung betrifft eine kraftaufnehmende Verbindung mit einem Kraftaufnahmeelement mit einem Innengewinde und einem Krafteinleitüngselement mit einer Bohrung für eine Schraube und ein Verfahren zur Herstellung einer solchen Verbindung.  The present invention relates to a force-absorbing connection with a force receiving member having an internal thread and a force introduction element with a bore for a screw and a method for producing such a compound.
[0002] Solche kraftaufnehmenden Verbindungen finden beispielsweise im Fahrzeugbau Verwendung, insbesondere bei der Verbindung von Fahrgestell und Fahrschemel (Achse). Bisher wurden hier einfache Schraubverbindungen eingesetzt. Dies hatte den Nachteil, dass solche Schraubverbindungen nicht mit vertretbarem Aufwand spielfrei herzustellen sind. Die Kraftübertragung erfolgte dabei stets über die entsprechende Reibung, Dies hatte zur Folge, dass auf sehr unebenen Untergründen das Fahrzeug zu quietschenden oder knarzenden Geräuschen neigte, da insbesondere nach längerer Laufdauer meist ein Verlust der Vorspannung eintritt und die Reibung dann erheblich geringer wird. Die Verbindung beginnt sich also unter Krafteinfluss zu bewegen. Such force-absorbing compounds are used for example in vehicle use, especially in the connection of the chassis and subframe (axle). So far, simple screw connections have been used here. This had the disadvantage that such screw connections can not be produced without play with reasonable effort. The result was that on very uneven ground, the vehicle tended to creaking or creaking noises, since especially after prolonged running time usually a loss of bias occurs and the friction is then significantly lower. The connection begins to move under the influence of force.

[0003] Zur Vermeidung eines solchen Spiels wurde bereits in der WO03/062653 A1 und der US 5,395,194 A vorgeschlagen, eine hohlzylindrische Stützhülse in eine Öffnung des einen Bauteils einzusetzen, durch die dann die Schraube zum Zwecke der Ver- schraubung hindurch tritt. Dabei wurden solche Stützhülsen bereits als hohlzylindrische Elemente mit parallel zu ihrer Axialrichtung verlaufenden Innensicken ausgebildet. Ähnliche, etwas abweichend ausgeführte Stutzhülsen sind beispielsweise auch aus der EP 2000681 A2 und der US 6,059,503 A bekannt.  In order to avoid such a play, it has already been proposed in WO03 / 062653 A1 and US Pat. No. 5,395,194 A to insert a hollow-cylindrical support sleeve into an opening of the one component, through which the screw then passes for the purpose of screwing. In this case, such support sleeves have already been formed as hollow cylindrical elements with parallel to their axial direction extending inner beads. Similar, somewhat deviating running sleeves are for example also known from EP 2000681 A2 and US 6,059,503 A.
[0004] Allen diesen Lösungen gemäß dem Stand der Technik ist jedoch weiterhin das Problem gegeben, dass bei sehr hohen Belastungen, beispielsweise im Falle eines Unfalls, nach dem Durchfedern der elastischen Stützhülse die gesamten Kräfte, insbesondere die Scherkräfte, auf den Schraubenschaft einwirken. Dadurch muss entweder die Schraube entsprechend groß, damit entsprechend schwer und aufwendig bemessen werden, oder man nimmt eine Zerstörung der Verbindung bei hohen Belastungen in Kauf.  However, all these solutions according to the prior art, the problem is still given that at very high loads, for example in the event of an accident, after the deflection of the elastic support sleeve, the entire forces, in particular the shear forces acting on the screw shank. As a result, either the screw has to be large enough to be correspondingly heavy and expensive, or a destruction of the connection at high loads is to be accepted.
Darstellung der Erfindung  Presentation of the invention
[0005] Es ist daher Aufgabe der vorliegenden Erfindung, ein solches kraftaufnehmendes Verbindungselement dergestalt weiterzubilden, dass eine spielfreie Verbindung er- möglicht wird, und ein Abreißen der Schraube auch im Unglücksfall nahezu ausgeschlossen werden kann. It is therefore an object of the present invention to develop such a force-absorbing connecting element in such a way that a backlash-free connection is achieved. is possible, and a tearing of the screw can be almost excluded even in the event of an accident.
[0006] Erfindungsgemäß wird diese Aufgabe dadurch gelöst, dass das Kraftaufnahmeelement zwischen dem Innengewinde und einer dem Krafteinleitungselement zugewandten Stirnfläche einen hohlzylindrischen Abschnitt mit einem Innendurchmesser aufweist, der deutlich größer als der Außendurchmesser der Schraube ist und das Krafteinleitungselement um die Bohrung herum mit einem sich auf das Kraftaufnahmeelement hin erstreckenden hohlzylindrischen Ansatz versehen ist, dessen Außendurchmesser etwa dem Innendurchmesser des hohlzylindrischen Abschnittes des Kraftaufnahmeelementes entspricht und der mit parallel zu seiner Axialrichtung verlaufenden Innensicken, Schlitzen oder Löchern versehen ist.  According to the invention, this object is achieved in that the force receiving element between the internal thread and a force introduction element facing end face has a hollow cylindrical portion having an inner diameter which is significantly larger than the outer diameter of the screw and the force introduction element around the bore with a on the hollow-cylindrical projection extending towards the force-receiving element is provided whose outer diameter corresponds approximately to the inner diameter of the hollow-cylindrical section of the force-receiving element and which is provided with inner beads, slots or holes running parallel to its axial direction.
[0007] Erfindungsgemäß werden also erstmals hohe Scherkräfte nicht mehr vom Schraubenschaft alleine aufgenommen, sondern durch die Verbindung zwischen dem hohlzylindrischen Abschnitt des Kraftaufnahmeelementes und den hohlzylindrischen Ansatz des Krafteinleitungselementes direkt zwischen den beiden Bauelementen übertragen. Trotzdem besteht durch die Elastizität des erfindungsgemäß ausgebildeten hohlzylindrischen Ansatzes ein ausreichender Spielausgleich für Herstellungstoleranzen, unterschiedliche thermische Ausdehnungen und Verformung der Bauelemente unter  Thus, according to the invention, high shear forces are no longer taken up by the screw shank alone for the first time, but rather are transmitted directly between the two components through the connection between the hollow-cylindrical section of the force-receiving element and the hollow-cylindrical projection of the force introduction element. Nevertheless, by the elasticity of the inventively embodied hollow cylindrical approach sufficient play compensation for manufacturing tolerances, different thermal expansions and deformation of the components under
Belastung.  Burden.
[0008] Besonders bevorzugt ist es dabei, wenn sich die Innensicken etwa bis auf den Außendurchmesser der Schraube nach innen erstrecken. Die Schraube bildet dann eine Art „Anschlag" für die Beweglichkeit des Ansatzes.  It is particularly preferred if the inner beads extend approximately to the outer diameter of the screw inwards. The screw then forms a kind of "stop" for the mobility of the approach.
[0009] Erfindungsgemäß wird diese Aufgabe auch durch ein Verfahren zur Verbindung  According to the invention this object is also achieved by a method of connection
zweier Bauteile durch eine Verschraubung mittels einer Schraube, einer Öffnung in dem einen Bauteil zum Durchtritt der Schraube und einem Innengewinde in dem anderen Bauteil zur Aufnahme der Schraube gelöst, indem die Öffnung in dem einen Bauteil mit einem hohlzylindrischen Ansatz versehen wird, der sich auf das andere Bauteil hin erstreckt, und das Innengewinde in dem anderen Bauteil von einem hohlzylindrischen Abschnitt umgeben wird, indem der hohlzylindrische Ansatz aufgenommen wird, wobei der hohlzylindrische Abschnitt mit parallel zu seiner Axialrichtung verlaufenden Innensicken, Schlitzen oder Löchern versehen ist.  two components solved by a screw by means of a screw, an opening in the one component for the passage of the screw and an internal thread in the other component for receiving the screw by the opening in the one component is provided with a hollow cylindrical projection, which is located on the extending other component, and the internal thread in the other component is surrounded by a hollow cylindrical portion by the hollow cylindrical projection is received, wherein the hollow cylindrical portion is provided with parallel to its axial direction extending inside beads, slots or holes.

bessere Zerstörungsfestigkeit der Verbindung insbesondere im Falle eines Unfalles erzielen.  achieve better destructive strength of the compound, especially in the event of an accident.

Bester Weg zur Ausführung der Erfindung  Best way to carry out the invention
[0016] Figur 1 zeigt ein erfindungsgemäßes kraftaufnehmendes Verbindungselement 10.  FIG. 1 shows an inventive force-absorbing connecting element 10.
Dieses ist in einem Rahmenteil 12, beispielsweise dem Teil eines Fahrwerkes eines Fahrzeuges beispielsweise durch Anschweißen montiert.  This is mounted in a frame part 12, for example, the part of a chassis of a vehicle, for example by welding.
[0017] Das Verbindungselement selbst besitzt eine Montageplatte 14, die ein Kraftaufnahmeelement 16 umfasst, und die der Befestigung des Verbindungselementes 10 an dem Rahmen 12 beispielsweise durch Schweißen dient.  The connecting element itself has a mounting plate 14 which includes a force receiving member 16, and which serves to attach the connecting element 10 to the frame 12, for example by welding.
[0018] Dieses Kraftaufnahmeelement 16 weist eine im Wesentlichen glockenförmige Form auf und trägt an seinem oberen Ende eine Bohrung 18 mit einem Innengewinde. Die übrige Form verläuft in der Form eines gestuften Hohlzylinders, der anschließend an die Bohrung 18 mit dem Innengewinde einen hohlzylindrischen Abschnitt 20 aufweist. Die Bohrung 18 mit dem Innengewinde und der hohlzylindrische Abschnitt 20 sind dabei jeweils koaxial und senkrecht zu der Oberfläche des Rahmenteils 12 angeordnet. Der Übergang dazwischen ist stufenförmig ausgebildet.  This force receiving element 16 has a substantially bell-shaped shape and carries at its upper end a bore 18 with an internal thread. The remainder of the mold runs in the form of a stepped hollow cylinder, which has a hollow-cylindrical section 20 following the bore 18 with the internal thread. The bore 18 with the internal thread and the hollow cylindrical portion 20 are each arranged coaxially and perpendicular to the surface of the frame part 12. The transition between them is stepped.
[0019] Weiter ist ein Krafteinleitungselement 24 vorgesehen, welches mittels einer Schraube 26 und einer gegebenenfalls unter dem Schraubenkopf angeordneten Beilagscheibe in dem Kraftaufnahmeelement 16 verschraubt ist. Dieses Krafteinleitungselement 24 kann mit dem weiteren Bauelement, beispielsweise einem Fahrschemel oder einer Achse eines Fahrzeuges verbunden sein.  Further, a force introduction element 24 is provided, which is screwed by means of a screw 26 and optionally arranged below the screw head washers in the force receiving element 16. This force introduction element 24 may be connected to the further component, for example a subframe or an axle of a vehicle.
[0020] Das Krafteinleitungselement 24 weist dabei die Außenform eines Zylinders auf, wobei die Durchtrittöffnung für die Schraube 26 von einem Zylinder 30 koaxial umgeben ist.  The force introduction element 24 has the outer shape of a cylinder, wherein the passage opening for the screw 26 is surrounded by a cylinder 30 coaxially.
[0021] Der zylindrische Ansatz 30, der die Durchtrittsöffnung für die Schraube 26 umgibt, weist einen Außendurchmesser auf, der in etwa dem Innendurchmesser des hohlzylindrischen Abschnitts 20 des Kraftaufnahmeelementes 16 entspricht.  The cylindrical projection 30, which surrounds the passage opening for the screw 26, has an outer diameter which corresponds approximately to the inner diameter of the hollow cylindrical portion 20 of the force receiving element 16.
[0022] Erfindungsgemäß ist dieser zylindrische Abschnitt 30 des Krafteinleitungselementes 24 dabei mit fünf um den Umfang herum gleich beabstandeten parallel zu der Rotationsachse der Bohrung für die Schraube 26 verlaufenden Innensicken 32 versehen.  According to the invention, this cylindrical portion 30 of the force introduction element 24 is provided with five around the circumference equally spaced parallel to the axis of rotation of the bore for the screw 26 extending inner beads 32.
[0023] Erfindungsgemäß dienen diese Sicken 32 dazu, den zylindrischen Abschnitt 30 in Umfangsrichtung federnd zu gestalten, sodass eine formschlüssige Verbindung zwischen dem zylindrischen Abschnitt 30 des Krafteinleitungselementes 24 und der hohlzylindrischen Innenfläche des Abschnittes 20 des Kraftaufnahmeelementes 16 gebildet wird. According to these beads 32 serve to make the cylindrical portion 30 resiliently in the circumferential direction, so that a positive connection is formed between the cylindrical portion 30 of the force introduction element 24 and the hollow cylindrical inner surface of the portion 20 of the force receiving element 16.
[0024] Zu diesem Zweck kann der Außendurchmesser des zylindrischen Abschnittes 30 des Krafteinleitungselementes 24 vor der Montage in dem Kraftaufnahmeelement 16 einen etwas größeren Außendurchmesser aufweisen als der Innendurchmesser des hohlzylindrischen Abschnittes 20 des Kraftaufnahmeelementes 16. Sodann wird dieser  For this purpose, the outer diameter of the cylindrical portion 30 of the force introduction element 24 prior to assembly in the force receiving element 16 has a slightly larger outer diameter than the inner diameter of the hollow cylindrical portion 20 of the force receiving element 16. Then this
Abschnitt beim Zusammenbau der beiden Teile in Umfangsrichtung leicht komprimiert, und auf diese Weise ist ein federnder Formschluss gesichert.  Section slightly compressed in the circumferential direction during assembly of the two parts, and in this way a resilient positive locking is secured.
[0025] Alternativ kann der Innendurchmesser des zylindrischen Abschnittes 30 des Krafteinleitungselementes 24 im Bereich der eingedrückten Innensicken 32 einen Innendurchmesser der Durchtrittsöffnung für die Schraube 26 bilden, der kleiner ist als der Außendurchmesser der Schraube 26. Durch Einsetzen der Schraube 26 wird der entsprechende Durchmesser dann so aufgeweitet, dass auf diese Weise der Formschluss mit dem hohlzylindrischen Abschnitt 20 des Kraftaufnahmeelementes 16 zustande kommt.  Alternatively, the inner diameter of the cylindrical portion 30 of the force introduction element 24 in the region of the indented inner beads 32 form an inner diameter of the passage opening for the screw 26, which is smaller than the outer diameter of the screw 26. By inserting the screw 26, the corresponding diameter is then so widened that in this way the positive connection with the hollow cylindrical portion 20 of the force receiving element 16 comes about.
[0026] Figur 2 zeigt die ungeschnittene Darstellung der Figur 1, sodass die„Glockenform" des Kraftaufnahmeelementes 16 auch von außen sehr deutlich wird.  Figure 2 shows the uncut view of Figure 1, so that the "bell shape" of the force receiving element 16 is also very clear from the outside.
[0027] Figur 3 zeigt den Schnitt senkrecht zur Rotationsachse der Figur 2. In dieser Darstellung werden die Innensicken 32 besonders deutlich. Es ist dabei besonders bevorzugt, wenn die Innensicken 32 so weit eingedrückt sind, dass sie innen an dem Schaft der Schraube 26 anliegen, während die Außenfläche des zylindrischen Abschnittes 30 gegen die Innenwand des hohlzylindrischen Abschnittes 20 des Kraftaufnahmeelementes 16 gedrückt wird. Alternativ zu den Innensicken 32 können auch Schlitze oder Löcher vorgesehen sein.  Figure 3 shows the section perpendicular to the axis of rotation of Figure 2. In this illustration, the inner beads 32 are particularly clear. It is particularly preferred if the inner beads 32 are pressed so far that they rest on the inside of the shaft of the screw 26, while the outer surface of the cylindrical portion 30 is pressed against the inner wall of the hollow cylindrical portion 20 of the force receiving member 16. As an alternative to the internal beads 32, slots or holes may also be provided.
[0028] Figur 4 zeigt schließlich ein erfindungsgemäßes kraftaufnehmendes Verbindungselement 10 in dreidimensionaler räumlicher Darstellung schräg von oben gesehen, wobei die Anbringung des Verbindungselementes 10 an dem Rahmen 12 besonders deutlich wird.  Finally, FIG. 4 shows an inventive force-receiving connecting element 10 in a three-dimensional spatial representation obliquely viewed from above, wherein the attachment of the connecting element 10 to the frame 12 becomes particularly clear.
[0029] Im Gegensatz zum Stand der Technik, bei dem eine reibschlüssige Verbindung mit einer normalen Verschraubung vorgesehen war, weist die erfindungsgemäße elastisch- formschlüssige Verbindung den großen Vorteil auf, dass im Einsatz bei Fahrzeugen Bodenerschütterungen und andere Beanspruchungen nicht mehr durch knarzende oder quietschende Geräusche bei der Verschiebung der reibschlüssigen Verbindung abgebildet werden. Des weiteren ist die erfindungsgemäße Verbindung in der Lage, erheblich größere Seitenkräfte, insbesondere im Falle eines Unfalles, aufzunehmen, da Krafteinleitungselement und Kraftaufnahmeelement direkt miteinander verzahnt sind, sodass die entsprechenden Belastungen nicht mehr über den Schaft der Schraube geführt werden müssen. Dies führt nämlich beim Stand der Technik im Falle von Unfällen häufig zu einem Abreißen der Schraube und damit zu einer Zerstörung der Verbindung. In contrast to the prior art, in which a frictional connection with a normal screw was provided, the elastic-positive connection according to the invention has the great advantage that when used in vehicles Bodenerschütterungen and other stresses no longer by creaking or squeaking noises be imaged during the displacement of the frictional connection. Furthermore, the compound according to the invention is able to absorb considerably larger lateral forces, in particular in the event of an accident, since the force introduction element and force receiving element are directly interlocked with each other so that the corresponding loads are no longer transmitted via the shaft of the screw must be led. This leads namely in the prior art in the event of accidents often to a tearing of the screw and thus to a destruction of the connection.
Darüber hinaus weist die erfindungsgemäße Krafteinleitung in den Rahmen 12 den Vorteil auf, dass die Kräfte günstiger, das heißt ohne so große Spitzen in den Rahmen eingeleitet werden, da der Kraftübergang nicht mehr an der Oberfläche des Rahmens, sondern innerhalb des Rahmens 12 erfolgt. Dadurch wird ein eventuelles Einknicken des Rahmens 12 im Überlastungsfalle hinausgezögert.  In addition, the force transmission according to the invention in the frame 12 has the advantage that the forces are cheaper, that is initiated without so large peaks in the frame, since the power transfer is no longer on the surface of the frame, but within the frame 12. As a result, a possible buckling of the frame 12 is delayed in the overload case.
