Description

Die Erfindung betrifft einen Anschlagpuffer nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a stop buffer according to the preamble of the claim 1.

Aus der DE 18 55 641 U ist ein Anschlagpuffer bekannt, der einen zylinderförmigen Endabschnitt aufweist, der mit Gewindegängen versehen ist. So kann der Anschlagpuffer mit dem zylinderförmigen Endabschnitt in eine Ausnehmung in einem Blechbauteil eingeschraubt werden. Über die Einschraubtiefe kann die Position des Anschlagpuffers eingestellt werden.From DE 18 55 641 U a stop buffer is known which has a cylindrical End portion having provided with threads. So the stop buffer with the cylindrical end portion in a recess in one Sheet metal component to be screwed. About the screwing can the position of the Stop buffers are set.

Aufgabe der Erfindung ist es, einen einstellbaren Anschlagpuffer zu schaffen, dessen Einstellung sich nicht durch mannigfaches Nutzen im Laufe der Zeit verändern kann.The object of the invention is to provide an adjustable stop buffer whose Attitude does not change through manifold benefits over time can.

Diese Aufgabe wird mit einem Anschlagpuffer mit den Merkmalen des Patentanspruchs 1 gelöst.This object is achieved with a bump stop with the features of the claim 1 solved.

Der erfindungsgemäße Anschlagpuffer weist ein Pufferbauteil und ein Aufnahmebauteil auf. Das Pufferbauteil hat einen Gewindeschaft, mit dem es in das Aufnahmebauteil einschraubbar ist, wobei das Pufferbauteil über die Einschraubtiefe einstellbar ist. Damit sich das Pufferbauteil nicht versehentlich verdrehen kann, ist eine Verdrehsicherung vorgesehen, die auf das Pufferbauteil und auf das Aufnahmebauteil aufsteckbar ist, und beide zumindest teilweise formschlüssig umgreift oder formschlüssig in diese eingreift. Die Verdrehsicherung stellt sicher, dass auch bei hohen Belastungen des Anschlagpuffers sich im Laufe der Zeit nicht das Pufferbauteil im Aufnahmebauteil verdrehen kann, sodass die gewünschte Einstellung des Anschlagpuffers nicht verloren gehen kann.The stop buffer according to the invention has a buffer component and a receiving component on. The buffer member has a threaded shank with which it is inserted into the receiving component can be screwed, wherein the buffer member adjustable over the depth of engagement is. So that the buffer component can not accidentally twist, is a Antirotation provided on the buffer member and on the receiving member can be plugged, and both at least partially positively engages or positively engages in these. The anti-rotation ensures that even at high Loads of the buffer stop over time not the buffer component in the Turning the receiving component so that the desired setting of the stop buffer can not be lost.

Günstigerweise weisen das Pufferbauteil und / oder das Aufnahmebauteil für den Formschluss eine Mantelfläche mit einem Querschnitt eines Vielecks mit n Ecken auf. Dies ist eine bewährte und besonders einfache Form, mit der ein verdrehsicherer Formschluss hergestellt werden kann. Die Verdrehsicherung weist dazu bevorzugt einen Abschnitt auf, der ein formschlüssiges Gegenstück zu dem Abschnitt des Bauteils mit dem Querschnitt eines Vielecks bildet. Wenn nun die Verdrehsicherung aufgesteckt werden soll, muss diese so aufgenommen oder gedreht werden, dass das Gegenstück mit seinen Ecken sich genau über den Ecken des Vielecks befindet, sodass es aufgesteckbar ist. Je mehr Ecken das Vieleck hat, um so weniger muss die Verdrehsicherung gedreht werden, bis sie passend zum Vieleck aufgesteckt werden kann. Je höher die Anzahl der Ecken ist, um so einfacher und schneller ist also die Montage. Bevorzugt weist das Vieleck daher zumindest 12 oder gar 18 Ecken auf. Dabei können die Abschnitte des Vielecks zwischen den einzelnen Ecken bogenförmig verlaufen. Die Bögen können dabei eine konvexe oder eine konkave Kontur wie beispielsweise bei einem Torx haben.Conveniently, the buffer member and / or the receiving member for the Positive fit a lateral surface with a cross section of a polygon with n corners on. This is a proven and very simple form, with a twist-proof Positive locking can be produced. The anti-rotation has for this purpose preferred a section which is a positive counterpart to the section of Component with the cross section of a polygon forms. If now the rotation should be plugged, this must be recorded or rotated so that the counterpart with its corners is just above the corners of the polygon, so that it is pluggable. The more corners the polygon has, the less the anti-twist device must be turned until it fits the polygon can be. The higher the number of corners, the easier and faster So is the assembly. The polygon therefore preferably has at least 12 or even 18 corners on. The sections of the polygon between the individual Corners are curved. The bows can be a convex or a have a concave contour, such as a Torx.

Wenn nun sowohl das Pufferbauteil als auch das Aufnahmebauteil für den Formschluss mit der Verdrehsicherung eine Mantelfläche mit einem Querschnitt eines Vielecks aufweisen, müssen das Pufferbauteil und das Aufnahmebauteil sich in einer definierten Position zueinander befinden, damit die Verdrehsicherung, die für beide Mantelflächen mit dem Querschnitt eines Vielecks ein Gegenstück bildet, aufsteckbar ist. Damit diese Positionierung des Pufferbauteils zum Aufnahmebauteil erleichtert werden kann oder im Idealfall komplett entfallen kann, weist günstigerweise der Formschluss zwischen der Verdrehsicherung und dem Pufferbauteil und / oder dem Aufnahmebauteil ein definiertes Verdrehspiel auf. Wenn dieses Spiel bevorzugt in beiden Drehrichtungen zusammen zumindest einem Winkel von 360° geteilt durch die Anzahl n der Ecken entspricht, kann das Ausrichten des Pufferbauteils zum Aufnahmebauteil sogar ganz entfallen. Dies stellt eine erhebliche Montagevereinfachung dar. Die dabei in Kauf zu nehmende maximale Verstellung des Pufferbauteils aufgrund dieses Spiels bewegt sich bei üblichen Gewindesteigungen im Bereich von 0,1 mm und weniger. If now both the buffer member and the receiving member for positive locking with the anti-rotation a lateral surface with a cross section of a Have polygon, the buffer member and the receiving member must be in a defined position to each other, so that the rotation, which for both lateral surfaces with the cross section of a polygon forms a counterpart, is pluggable. Thus, this positioning of the buffer member to the receiving component can be relieved or completely eliminated in the ideal case, points favorably the positive connection between the anti-twist device and the buffer component and / or the receiving member on a defined backlash. If preferred this game in both directions together at least an angle of 360 ° divided by the number n of corners corresponds to the alignment of the buffer component even completely omitted the recording component. This represents a considerable simplification of assembly dar. The thereby to be accepted maximum adjustment of the Buffer due to this game moves at usual thread pitches in the range of 0.1 mm and less.

In the drawing, an embodiment of the invention is shown, by which the invention will be described in more detail below. The individual figures show in a schematic representation:

a bottom view of the stop buffer without rotation.

In Fig. 1 ist ein Anschlagpuffer 1 dargestellt, der bei einem Kraftfahrzeug verhindert, dass eine Heckklappe beim Schließen direkt auf die Karosserie auftreffen kann. Der Anschlagpuffer besteht aus einem eigentlichen Pufferbauteil 2, das aus einem Pufferkopf 3 aus einem weichen Material besteht, und einem Gewindeschaft 4 mit Aufnahmekopf 5, auf dem der Pufferkopf 3 gehalten ist. Das Pufferbauteil 2 ist mit seinem Gewindeschaft 4 in ein buchsenartiges Aufnahmebauteil 6 eingeschraubt. Das Aufnahmebauteil 6 wiederum ist in eine Ausnehmung eines Blechbauteils 7 der Kraftfahrzeugkarosserie eingesetzt. Es liegt auf der einen Seite mit seinem Kragen 8 am Blechbauteil 7 an und ist von der anderen Seite her mit einer aufgeschraubten Mutter 9 gesichert. Günstigerweise hat die Ausnehmung im Blechbauteil 7 anstelle einer runden Form eine eckige Form, und der entsprechende Abschnitt des Aufnahmebauteils 6 weist ebenfalls eine entsprechende eckige Form auf, sodass ein Verdrehen des Aufnahmebauteils 6 mit der Mutter 9 in der Ausnehmung im Blechbauteil 7 ausgeschlossen werden kann.In Fig. 1, a stop buffer 1 is shown, which prevents in a motor vehicle, that a tailgate can hit directly on the body when closing. Of the Buffer consists of an actual buffer member 2, which consists of a buffer head 3 consists of a soft material, and a threaded shaft 4 with recording head 5, on which the buffer head 3 is held. The buffer member 2 is with his Threaded shaft 4 screwed into a socket-like receiving member 6. The Receptacle 6 in turn is in a recess of a sheet metal component 7 of Used vehicle body. It lies on one side with its collar 8 on the sheet metal part 7 and is from the other side with a screwed Mother 9 secured. Conveniently, the recess in the sheet metal component 7 instead a round shape an angular shape, and the corresponding portion of the receiving member 6 also has a corresponding angular shape, so that a Rotating the receiving member 6 with the nut 9 in the recess in the sheet metal component 7 can be excluded.

Der Pufferkopf 3 des Pufferbauteils 2 kann sich je nach Einschraubtiefe des Gewindeschafts 4 unterschiedlich weit nach oben über das Blechbauteil 7 hinaus erheben und kann so über die Einschraubtiefe eingestellt werden. Damit das Verändern der Einschraubtiefe leicht möglich ist, ist am freien Ende des Gewindeschafts 4 in axialer Verlängerung ein Körper 10 mit einem sechseckigen Querschnitt angebracht. Dieser Körper 10 ragt über das Aufnahmebauteil 6 hinaus nach unten. Die Kanten des sechseckigen Querschnitts zwischen den Ecken sind nach innen gewölbt. An diesem Körper 10 kann leicht ein Werkzeug mit einem Hebelarm angesetzt werden, das den Körper 10 zumindest teilweise formschlüssig umgreift, sodass das Pufferbauteil 2 mit Hilfe dieses Werkzeugs leicht in die gewünschte Position durch ein Verändern der Einschraubtiefe gedreht werden kann.The buffer head 3 of the buffer member 2 may be depending on the depth of thread of the threaded shaft 4 differently far up above the sheet metal part 7 also raise and can thus be adjusted via the screw-in depth. So that changing the Screwing is easily possible, is at the free end of the threaded shaft 4 in axial Extension a body 10 attached with a hexagonal cross-section. This body 10 projects beyond the receiving member 6 also down. The edges of the hexagonal cross section between the corners are curved inwards. At this body 10 can be easily attached to a tool with a lever arm, that at least partially positively surrounds the body 10, so that the buffer member 2 with the help of this tool easily in the desired position by a Changing the screwing can be rotated.

Der Abschnitt 11 des Aufnahmebauteils 6, das dem Körper 10 zugewandt ist, weist ebenfalls eine Mantelfläche mit einem Querschnitt eines Vielecks mit zwölf Ecken auf. Auf den Körper 10 des Pufferbauteils 2 und auf den Abschnitt 11 des Aufnahmebauteils 6 mit der Mantelfläche mit dem Querschnitt eines Vielecks ist eine Verdrehsicherung 12 aufsteckbar, die formschlüssig den sechseckigen Körper 10 und den Abschnitt 11 umgreift. Dadurch kann das Pufferbauteil 2 nicht mehr relativ zum Aufnahmebauteil 6 verdreht werden. Die formschlüssige Gegenform der Verdrehsicherung 12 zum Körper 10 ist so gestaltet, dass die aufgesteckte Verdrehsicherung 12 noch ein Verdrehspiel von +/- 15° aufweist. Dies entspricht insgesamt einem maximalen Verdrehweg von 30° bzw. 360° dividiert durch die Anzahl der Ecken des Abschnitts 11. Auf diese Weise kann die Verdrehsicherung 12 immer aufgesteckt werden, ohne dass zuvor das Aufnahmebauteil 6 und das Pufferbauteil 2 dazu zueinander ausgerichtet werden müssen. Das Spiel von +/- 15° ergibt bei einem Gewinde M12 mit einer Gewindesteigung von 1,75 mm nur eine maximale Höhendifferenz des Pufferkopfes 3 von +/- 0,073 mm, sodass das Verdrehspiel keinen nennenswerten Einfluss auf die Einstellung des Anschlagpuffers 1 hat.The portion 11 of the receiving member 6, which faces the body 10, has also a lateral surface with a cross section of a polygon with twelve corners on. On the body 10 of the buffer member 2 and on the portion 11 of the receiving member 6 with the lateral surface with the cross section of a polygon is a rotation 12 attachable, the form-fitting hexagonal body 10 and encompasses section 11. As a result, the buffer member 2 is no longer relative to Shooting member 6 are rotated. The form-fitting counter-form of the anti-twist device 12 to the body 10 is designed so that the plugged against rotation 12 still has a torsional backlash of +/- 15 °. This corresponds to one total maximum rotational travel of 30 ° or 360 ° divided by the number of corners of the Section 11. In this way, the rotation 12 can always plugged be without previously the receiving member 6 and the buffer member 2 to each other have to be aligned. The game of +/- 15 ° results in a thread M12 with a thread pitch of 1.75 mm only a maximum height difference of the buffer head 3 of +/- 0.073 mm, so that the backlash no significant Influence on the setting of the stop buffer 1 has.

Die Verdrehsicherung 12 weist an zwei einander gegenüber liegenden Seiten jeweils eine Rastnase 13 auf. Diese Rastnasen 13 können in einem Einstich 14 im Aufnahmebauteil 6 hinter dem Abschnitt 1 verrasten, wenn die Verdrehsicherung 12 vollständig aufgesteckt ist. Dadurch kann die Verdrehsicherung 12 sich nicht versehentlich vom Aufnahmebauteil 6 lösen.The anti-rotation 12 has at two opposite sides each a latch 13. These locking lugs 13 may be in a groove 14 in Lock the receiving component 6 behind the section 1 when the anti-twist device 12 completely plugged in. As a result, the anti-rotation 12 is not accidentally from the receiving component 6.

Der Anschlagpuffer 1 befindet sich mit dem Pufferkopf 3 im wasserführenden Bereich der Fahrzeugkarosserie, während der Körper 10 zur Einstellung des Pufferkopfes 3 sich auf der anderen Seite des Blechbauteils 7 im trockenen Bereich der Fahrzeugkarosserie befindet. Um zu verhindern, dass zwischen Blechbauteil 7 und Aufnahmebauteil 6 vom wasserführenden Bereich in den trockenen Bereich eindringen kann, besteht das Aufnahmebauteil 6 aus einem Kunststoff, an den in einem Zweikomponentenspritzverfahren auf der Unterseite des Aufnahmekopfes 5 Zweikomponentenspritzverfahren auf der Unterseite des Aufnahmekopfes 5 umlaufend ein Dichtungssteg 15 aus einem weichen, gummiartigen Material angespritzt ist. Auch zwischen dem Aufnahmebauteil 6 und dem Pufferbauteil 2 könnte Wasser durch die Gewindegänge hindurch in den trockenen Bereich eindringen. Um dies zu verhindern, sind wiederum am Aufnahmebauteil 2 umlaufende dichtende Stege 16 am oberen Rand des Gewindes im Aufnahmebauteil 2 angespritzt, die bei eingeschraubtem Pufferbauteil 2 dichtend am Gewindeschaft 4 anliegen.The bump stop 1 is located with the buffer head 3 in the water-bearing area the vehicle body, while the body 10 for adjusting the Buffer head 3 on the other side of the sheet metal component 7 in the dry area the vehicle body is located. To prevent that between sheet metal part 7th and receiving component 6 from the water-bearing area to the dry area can penetrate, the receiving member 6 consists of a plastic, to the in a two-component injection method on the underside of the receiving head. 5 Two-component spraying method on the underside of the receiving head 5 revolving a sealing web 15 molded from a soft, rubber-like material is. Also between the receiving member 6 and the buffer member 2 could be water penetrate through the threads into the dry area. To this, too prevent, turn on the receiving member 2 circumferential sealing webs 16th injected at the upper edge of the thread in the receiving member 2, which screwed in at Buffer component 2 sealingly abut the threaded shaft 4.

In Fig. 2a ist eine Unteransicht der Verdrehsicherung 12 dargestellt. Dabei ist mittig gut der Abschnitt zu erkennen, der die Gegenform zum Körper 10 des Pufferbauteils 2 bildet. Im Vergleich dazu ist in Fig. 2b eine Unteransicht des Pufferbauteils 2 dargestellt. In der Gegenüberstellung der Unteransicht der Verdrehsicherung 12 mit der Unteransicht des Pufferbauteils 2 ist der mögliche Formschluss der beiden Bauteile zueinander gut sichtbar. Auch das bei einem Formschluss vorhandene Verdrehspiel ist erkennbar. Maßgeblich für dieses Verdrehspiel ist einerseits die torxähnliche Querschnittsform des Körpers 10, und andererseits die rosettenartige Gegenform der Verdrehsicherung 12.In Fig. 2a, a bottom view of the anti-rotation 12 is shown. It is in the middle good to recognize the portion of the counter-shape to the body 10 of the buffer member 2 forms. In comparison, a bottom view of the buffer member 2 is shown in Fig. 2b. In the comparison of the bottom view of the rotation 12 with the Bottom view of the buffer member 2 is the possible positive connection of the two components clearly visible to each other. Also, the existing in a positive fit backlash is recognizable. Decisive for this backlash is on the one hand the torx-like Cross-sectional shape of the body 10, and on the other hand, the rosette-like counter-shape the anti-rotation 12th
