Description

Die Erfindung betrifft eine Schraube, insbesondere eine Stellschraube zum Einstellen eines definierten Spiels eines Druckstücks, die in ein Lenkgetriebegehäuse einschraubbar ist, wobei das Lenkgetriebegehäuse eine Einschrauböffnung und ein Innengewinde aufweist und zwischen der Einschrauböffnung und dem Anfang des Innengewindes ein Bereich vorgesehen ist mit einem Innendurchmesser, der mindestens so groß ist wie der Fußkreisdurchmesser des Innengewindes.The invention relates to a screw, in particular an adjusting screw for adjusting a defined play of a pressure piece, which is screwed into a steering gear housing, wherein the steering gear housing has a screw-in opening and an internal thread and between the screw-in and the beginning of the internal thread a region is provided with an inner diameter, which is at least as large as the root diameter of the internal thread.

Bei mechanischen, hydraulischen und elektrischen Zahnstangenlenkungen wird im Allgemeinen nach dem Einstellen des Spiels des Druckstücks die Stellschraube im Bereich des Gewindes verstemmt, um sie gegen ein unerwünschtes Verdrehen zu sichern. Durch die zeitgemäßen Fertigungsverfahren bedingt, weist jedoch das Lenkgetriebegehäuse den oben genannten Bereich auf, in dem sich kein Innengewinde befindet und somit Material fehlt, das zum Verstemmen genutzt werden kann.In mechanical, hydraulic and electric rack and pinion steering, the adjusting screw in the region of the thread is generally caulked after setting the play of the pressure piece in order to secure it against undesired rotation. Due to the contemporary manufacturing process, however, the steering gear housing on the above-mentioned area in which there is no internal thread and thus lacks material that can be used for caulking.

In der DE 10 2005 002 606 A1 wird eine Vorrichtung zum Andrücken einer Zahnstange an ein mit der Zahnstange in Eingriff stehendes Ritzel beschrieben, bei der die Stellschraube durch eine formschlüssige Verbindung gesichert wird. Zur Herstellung der formschlüssigen Verbindung zwischen der Stellschraube und dem Lenkgetriebegehäuse wird ein zwischen der Stellschraube und dem Lenkgetriebegehäuse gebildeter Hohlraum mit einem Werkstoff vergossen.In the DE 10 2005 002 606 A1 a device for pressing a rack is described to a standing with the rack engaging pinion, wherein the screw is secured by a positive connection. To produce the positive connection between the screw and the steering gear housing formed between the screw and the steering gear housing cavity is shed with a material.

Eine andere Lösungsvariante beschreibt die DE 10 2004 041 697 A1 , bei der die Stellschraube mindestens eine Auskragung aufweist, die radial über das Gewinde der Stellschraube hinausragt und mit einer Außenfläche der Gewindebohrung verstemmbar ist.Another solution variant describes the DE 10 2004 041 697 A1 in which the adjusting screw has at least one projection which projects radially beyond the thread of the adjusting screw and can be caulked with an outer surface of the threaded bore.

Beide aus dem Stand der Technik bekannten Lösungsvarianten erfüllen zwar in der Praxis ihren Zweck, jedoch zeigt die Praxis auch, dass sie nicht zur Lösung der sich aus den oben genannten zeitgemäßen Fertigungsverfahren ergebenden Probleme geeignet sind.Although both known from the prior art solution variants meet their purpose in practice, however, the practice also shows that they are not suitable for solving the problems arising from the above-mentioned contemporary manufacturing processes.

Die Erfindung hat deshalb die Aufgabe, die gattungsgemäße Schraube dahingehend zu verbessern, dass auch mit ihr eine sichere und zuverlässige Verstemmung der Schraube möglich ist.The invention therefore has the task of improving the generic screw to the effect that with her a safe and reliable caulking of the screw is possible.

Die Erfindung löst die gestellte Aufgabe mit einer Schraube der eingangs genannten Art, bei der sich erfindungsgemäß an einen Bereich zwischen einer Einschrauböffnung und einem Anfang eines Innengewindes mindestens eine Ausnehmung anschließt, deren Tiefe mindestens so groß ist wie der Abstand von der Einschrauböffnung bis zum Anfang des Innengewindes, wobei in einen Grund der Ausnehmung eine die Schraube verstemmende Vertiefung einbringbar ist. Wenn die Vertiefung in den Grund der Ausnehmung eingebracht wird, wird dadurch Material des Lenkgetriebegehäuses wenigstens bereichsweise in das Gewinde der Schraube hinein verstemmt, so dass die Schraube formschlüssig gesichert ist.The invention solves this problem with a screw of the type mentioned, in which according to the invention at least one recess adjoins a region between a screw-in and a start of an internal thread whose depth is at least as large as the distance from the screw-in to the beginning of Internal thread, wherein in a bottom of the recess a stiffening the screw depression can be introduced. If the recess is introduced into the bottom of the recess, thereby material of the steering gear housing is at least partially caulked into the thread of the screw, so that the screw is secured in a form-fitting manner.

Die Erfindung betrifft außerdem eine Schraube der eingangs genannten Art, bei der sich erfindungsgemäß an den Bereich zwischen der Einschrauböffnung und dem Anfang des Innengewindes die mindestens eine Ausnehmungen anschließt, deren Tiefe mindestens so groß ist wie der Abstand von der Einschrauböffnung bis zum Anfang des Innengewindes, wobei die Schraube aus einem thermoplastischen Material hergestellt und in der Weise erwärmbar und verformbar ist, so dass ein Teil des Materials in die Ausnehmung hinein verstemmbar ist. Folglich wird auch durch diese Lösung die Schraube formschlüssig gesichert, so dass eine Verstellung eines genau definierten Spiels eines Druckstücks zuverlässig ausgeschlossen ist.The invention also relates to a screw of the type mentioned, in which according to the invention adjoins the region between the screw-in and the beginning of the internal thread, the at least one recesses whose depth is at least as large as the distance from the screw hole to the beginning of the internal thread, wherein the screw is made of a thermoplastic material and in such a way heatable and deformable, so that a part of the material can be caulked into the recess. Consequently, the screw is positively secured by this solution, so that an adjustment of a well-defined game of a pressure piece is reliably excluded.

Besonders gute Ergebnisse hinsichtlich eines Verstemmens des Gewindes der Schraube erreicht man, wenn die Vertiefung im Schnitt betrachtet V-förmig oder rechteckig oder ausgerundet ist. Dann wird das Material des Lenkgetriebegehäuses besonders gut in das Gewinde der Schraube hinein verstemmt.Particularly good results with respect to a caulking of the thread of the screw can be achieved if the recess is viewed in section V-shaped or rectangular or rounded. Then the material of the steering gear housing is particularly well caulked into the thread of the screw.

Um eine gleichmäßige und somit zuverlässige Verstemmung der Schraube zu erreichen, können die Ausnehmungen in einem Winkel von 90° oder 120° angeordnet sein. Selbstverständlich sind auch andere Winkel möglich.In order to achieve a uniform and thus reliable caulking of the screw, the recesses may be arranged at an angle of 90 ° or 120 °. Of course, other angles are possible.

Die Erfindung betrifft ferner ein Verstemmwerkzeug zum wenigstens bereichsweise Verstemmen des Gewindes der Schraube, die in das Lenkgetriebegehäuse einschraubbar ist, das zwischen der Einschrauböffnung und dem Anfang des Innengewindes den Bereich mit dem Innendurchmesser aufweist, der mindestens so groß ist wie der Fußkreisdurchmesser des Innengewindes, mit mindestens einem Verstemmstempel, der auf einem Stempelträger angeordnet ist.The invention further relates to a caulking for at least partially caulking the thread of the screw, which is screwed into the steering gear housing having between the screw and the beginning of the internal thread the region with the inner diameter which is at least as large as the root diameter of the internal thread, with at least one Verstemmstempel which is arranged on a punch carrier.

Neben dem mindestens einen Verstemmstempel kann eine Anschlagfläche vorgesehen sein, die am Ende des Verstemmvorgangs gegen den Grund der mindestens einen Ausnehmung anschlägt. Somit kann eine Verstemmung durchgeführt werden, bei der eine genau definierte Menge des Materials des Lenkgetriebegehäuses in das Gewinde der Schraube hinein verdrängt wird.In addition to the at least one Verstemmstempel may be provided a stop surface which abuts against the bottom of the at least one recess at the end of Verstemmvorgangs. Thus, a caulking can be performed in which a well-defined amount of the material of the steering gear housing is displaced into the thread of the screw.

Entsprechend der optimalen Anzahl an Ausnehmungen kann der Verstemmstempel 3, 4, 6 oder 8 Verstemmstempel aufweisen, die auf einem Kreis angeordnet sind, dessen Durchmesser mindestens etwas größer ist als der Fußkreisdurchmesser des Innengewindes. According to the optimum number of recesses, the caulking can have 3, 4, 6 or 8 Verstemmstempel, which are arranged on a circle whose diameter is at least slightly larger than the root diameter of the internal thread.

Nachfolgend werden bevorzugte Ausführungsbeispiele der Erfindungen anhand der beiliegenden Zeichnungen näher erläutert.Hereinafter, preferred embodiments of the invention will be explained in more detail with reference to the accompanying drawings.

1 zeigt ein Lenkgetriebe 10 mit einem Lenkgetriebegehäuse 11. Das Lenkgetriebe 10 weist eine Zahnstange 12 auf, gegen die ein Druckstück 13 drückt. Ein Ritzel 14 ist mittels eines Festlagers 15 und eines Loslagers 16 gelagert und greift in die Zahnstange 12 ein. Das Druckstück 13 drückt mittels einer Feder 17 die Zahnstange 12 gegen das Ritzel 14, so dass das Ritzel 14 spielfrei in die Zahnstange 12 eingreifen kann. Eine Schraube 18, welche die Funktion einer Stellschraube hat, wird bei der Endmontage des Lenkgetriebes so weit eingeschraubt, dass zwischen ihr und dem Druckstück 13 ein definiertes Spiel 19 sichergestellt ist. Damit die Schraube 18 ihre das Spiel 19 definierende Stellung beibehalten kann, wird sie verstemmt. 1 shows a steering gear 10 with a steering gear housing 11 , The steering gear 10 has a rack 12 on, against which a pressure piece 13 suppressed. A pinion 14 is by means of a fixed camp 15 and a floating camp 16 stored and engages in the rack 12 one. The pressure piece 13 pushes by means of a spring 17 the rack 12 against the pinion 14 so the pinion 14 backlash in the rack 12 can intervene. A screw 18 , which has the function of a set screw, is screwed in during final assembly of the steering gear so far that between it and the pressure piece 13 a defined game 19 is ensured. So the screw 18 their the game 19 retaining a defining position, it is caulked.

2 zeigt das Lenkgetriebegehäuse 11 und die Schraube 18, wobei in dem Lenkgetriebegehäuse 11 eine Einschrauböffnung 20 und ein Innengewinde 21 vorgesehen sind. Gemäß dem Stand der Technik befindet sich zwischen der Einschrauböffnung 20 und dem Anfang des Innengewindes 21 ein Bereich 22, der einen Innendurchmesser aufweist, der größer ist als der Fußkreisdurchmesser des Innengewindes 21. Deshalb könnte mit einer oberhalb des Bereichs 22 vorgesehenen Vertiefung kein Material des Lenkgetriebegehäuses 11 in ein Gewinde 23 der Schraube 18 verstemmt werden. Das Material könnte sich bestenfalls außen an die Schraube 18 anlegen, wodurch sie aber nicht verstemmt würde. 2 shows the steering gear housing 11 and the screw 18 , wherein in the steering gear housing 11 a screw-in opening 20 and an internal thread 21 are provided. According to the prior art is located between the screw-in 20 and the beginning of the internal thread 21 an area 22 which has an inner diameter which is larger than the root diameter of the internal thread 21 , That could be why with one above the range 22 provided recess no material of the steering gear housing 11 in a thread 23 the screw 18 be caulked. The material could at best be outside the screw 18 create, but it would not caulked.

In 3 schließt sich oberhalb des Bereichs 22 eine Ausnehmung 30 an, deren Tiefe genauso groß ist wie der Abstand von der Einschrauböffnung 20 bis zum Anfang des Innengewindes 21. In einen Grund 31 der Ausnehmung 30 ist eine Vertiefung 32 eingebracht, die sich oberhalb und hinter dem Anfang des Innengewindes 21 befindet.
