Description
Die Erfindung betrifft eine Befestigung eines Getriebeelementes in einem Kraftfahrzeug gemäß dem Oberbegriff von Anspruch 1.The The invention relates to a fastening of a transmission element in one Motor vehicle according to the preamble of claim 1.
Aus
der
Bei dieser vorbekannten Einrichtung ist das Schneckenrad als Antriebselement auf einen Gewindeabschnitt der Spindel (Abtriebselement) aufgedreht. Damit die Spindel von dem Schneckenrad getrieben werden kann, muss die Verbindung der beiden Getriebeteile Spindel – Schneckenrad drehfest sein und die axialen Kräfte der Verstelleinrichtung aufnehmen können. Dies kann durch Aufbringen von Klebstoff auf den Gewindeabschnitt erfolgen. Auch ist es möglich, das Schneckenrad mit seinem Gewinde mittels einer zweiten Mutter zu kontern. Letztlich ist es auch bekannt, das Schneckenrad mittels einem Vielnutprofil auf der Spindel drehfest zu verbinden und mit einer Mutter zu sichern.at This known device is the worm wheel as a drive element turned on a threaded portion of the spindle (output member). So that the spindle can be driven by the worm wheel, must the connection of the two gear parts spindle - worm wheel be rotationally fixed and the axial forces can accommodate the adjustment. This can be done by applying from adhesive to the threaded section. Also it is possible that Worm wheel with its thread by means of a second nut too counter. Finally, it is also known, the worm wheel means a Vielnutprofil on the spindle rotatably connect and with to secure a mother.
Aufgabe der vorliegenden Erfindung ist es daher, eine Befestigung eines Getriebeelementes in einem Kraftfahrzeug nach dem Oberbegriff von Anspruch 1 weiterzubilden.task The present invention is therefore an attachment of a Transmission element in a motor vehicle according to the preamble of To further develop claim 1.
Gelöst wird diese Aufgabe durch die kennzeichnenden Merkmale von Anspruch 1. Weiterbildungen der Erfindung ergeben sich aus den jeweiligen Unteransprüchen.Is solved This object is achieved by the characterizing features of claim 1. Further developments of the invention will become apparent from the respective dependent claims.
Nach der Erfindung ist vorgesehen, dass wenigstens eine der bei der Verbindung der Getriebeelemente miteinander in Kontakt kommenden Oberflächen Deformationen im Sinne von Aufwertungen aufweist, welche eine von der Grundform der jeweiligen Oberfläche abweichende Geometrie ergeben. So ist nach einer Ausführungsform der Erfindung vorgesehen, dass der zur Aufnahme des Schneckenrades vorgesehene Oberflächenabschnitt der Gewindespindel durch Rillung oder Rändelung erzeugte Aufwerfungen aufweist. Das Schneckenrad wird dann bspw. mittels einer Dreh- und/oder Vorschubbewegung der Spindel auf dieser befestigt. Die Befestigung des Schneckenrades erfolgt, bedingt durch die Bewegungen und die Aufwertungen, nach dem Prinzip einer Reibschweißung – entsprechende Materialpaarung zwischen An- und Abtriebselement vorausgesetzt. Somit ist die Verbindung von Schneckenrad und Spindel bis zu einem maximalen Drehmoment drehfest. Das maximal übertragbare Drehmoment ist hierbei durch die Gestaltung der Aufwertungen, die Bemaßung der Teile zueinander sowie den Prozess des Zusammenfügens (Drehzahl, Geschwindigkeit des Drehens, der Vorschubbewegung) beeinflussbar.To The invention provides that at least one of the compound the transmission elements come into contact with one another surface deformations in the sense of upgrades, which one of the basic form the respective surface give different geometry. So, according to one embodiment the invention provided that provided for receiving the worm wheel surface section the threaded spindle caused by grooving or knurling Aufwerfungen having. The worm wheel is then, for example, by means of a rotary and / or Feed movement of the spindle mounted on this. The attachment of the worm wheel, due to the movements and the Upgrades, according to the principle of friction welding - corresponding material pairing assumed between input and output element. Thus, the connection from worm wheel and spindle up to a maximum torque rotation. The maximum transferable Torque is here by the design of the revaluations, the dimensioning of Parts to each other and the process of assembly (speed, speed of Turning, the feed movement) influenced.
Nach einer Ausführungsform der Erfindung ist vorgesehen, dass die durch Rillung, Rändelung oder eine durch geeignete Bearbeitung erzeugten Aufwerfungen/Verformungen im Bereich eines das Schneckenrad aufnehmendens Gewindes der Spindel angebracht sind. Hier können gerade und in Achsrichtung der Spindel verlaufende Rillen vorgesehen sein, ferner kann das Gewinde auch mittels Kreuzrändelung, schräg verlaufenden Rillen bzw. mit einer gegenläufig zum Gewinde verlaufenden Spiralstruktur (Spiralrille) deformiert sein. Diese Gewindedeformationen ermöglichen ebenfalls und wie bereits erläutert eine beim Aufdrehen des Schneckenrades erzeugbare Reibschweißverbindung zwischen diesen Getriebeteilen. Auch hier ist die Verbindung von Schneckenrad und Spindel bis zu einem maximalen Drehmoment drehfest.To an embodiment the invention is intended that by grooving, knurling or a warp / deformation created by suitable machining in the area of the worm wheel receiving thread of the spindle are attached. here we can provided straight and running in the axial direction of the spindle grooves Furthermore, the thread can also by means of Kreuzrändelung, aslant extending grooves or with a counter to the thread running Spiral structure (spiral groove) to be deformed. These thread deformations enable also and as already explained a produceable when unscrewing the worm wheel Reibschweißverbindung between these gear parts. Again, the connection of worm wheel and spindle rotatably to a maximum torque.
Weiterführend kann vorgesehen sein, das Gewinde lediglich an einer Oberfläche eines der Getriebeelemente anzubringen. Bspw. kann lediglich die Verstellspindel in einem Bereich das Gewinde aufweisen – mittels Dreh- und Vorschubbewegung wird die Spindel in die Öffnung des Schneckenrades eingedreht. Besonders eignet sich diese Befestigung, wenn die Spindel aus Metall, das darauf zu befestigende Getriebeelement aus einem Kunststoff besteht. Durch die beim Eindrehen der Spindel in die Öffnung des Getriebeelementes entstehende Reibungswärme weicht der Kunststoff auf – nach Beendigung des Eindrehvorganges verfestigt dieser wieder, so dass sich eine drehfeste Verbindung ergibt. Die erfindungsgemäß vorgesehenen Deformationen verstärkt hierbei die Erzeugung von Reibungswärme und in den Zwischenräumen (Traggrund) kann sich der Kunststoff verankern.Can continue be provided, the thread only on a surface of a to install the transmission elements. For example. can only the adjusting spindle in one area have the thread - by means of rotation and feed movement the spindle is in the opening the worm wheel screwed. This attachment is particularly suitable when the spindle made of metal, the gear element to be fastened thereon made of a plastic. By when screwing in the spindle in the opening The frictional heat generated by the transmission element softens the plastic - after completion the screwing process solidifies this again, so that a rotatable connection results. The inventively provided deformations amplified here the generation of frictional heat and in the interstices (Base), the plastic can anchor.
Bei einer weiteren bevorzugten Ausführungsform der Erfindung ist vorgesehen, das auf den die Deformationen aufweisenden Gewinde aufgeschraubte Schneckenrad zusätzlich mittels Klebstoff zu befestigen. Vorzugsweise ist die Deformation des Gewindes dergestalt, dass das Schneckenrad absolut spielfrei aufgeschraubt werden kann und der Klebstoff zwischen den Gewindeflächen in Ruhe, also ohne störende Bewegungen der Bauteile relativ zueinander aushärten kann. Eine Relativbewegungen der Bauteile zueinander unterbindende Fixierung während der Aushärtung des Klebstoffes ist somit nicht erforderlich. Statt einem Klebstoff kann auch ein der Gewindesicherung dienendes Mittel verwendet werden. Verwendbar wäre hier insbesondere ein nach dem Prinzip der Mikroverkapselung arbeitendes Mittel. Durch das spielfreie Verkleben der Getriebeelemente ergibt sich auch eine exakte Ausrichtung der Spindel – diese kann im späteren Betrieb nicht schlagen und so Lagerungen oder andere Bauteile schädigen.In a further preferred embodiment of the invention, it is provided to additionally fasten the worm wheel screwed onto the thread having the deformations by means of adhesive. Preferably, the deformation of the thread is such that the worm wheel can be screwed absolutely free of play and the adhesive between the threaded surfaces at rest, so without disturbing movements of the components can harden relative to each other. A relative movements of the components to each other preventing fixation during the curing of the adhesive is thus not mandatory. Instead of an adhesive can also be used a thread securing agent. In this case, it would be possible to use, in particular, an agent operating on the principle of microencapsulation. The play-free bonding of the gear elements also results in an exact alignment of the spindle - this can not beat in later operation and damage so storage or other components.
Bei dem zusätzlichen Verkleben bzw. dem durch Mikroverkapselung bewirkten Sichern des deformierten Gewindes bewirken die Gewindedeformationen neben der zuvor erläuterten Spielausstellung während des Klebens ebenfalls eine bessere Verteilung des Klebe- bzw. Sicherungsmittels während des Eindrehens der Teile. Ferner findet das Klebe- bzw. Sicherungsmittel einen besseren Traggrund. Bei Verwendung eines Klebstoffes, welcher durch Wärmeeintrag aushärtet, bewirken die Deformationen während der Fügebewegung eine zusätzliche Reibungswärme, so dass der Klebeprozess verbessert wird. Diese Wirkungen ergeben sich übrigens auch bei den Ausführungen der Erfindung, bei welchen die Getriebeteile kein Gewinde bzw. eine gewindeähnliche Struktur aufweisen.at the additional Sticking or the microencapsulation ensured by securing the deformed thread cause the thread deformations next to the previously explained Play exhibition during the gluing also a better distribution of the adhesive or securing means while screwing in the parts. Furthermore, the adhesive or securing means a better base. When using an adhesive, which by heat input cures cause the deformations during the joining movement an additional Frictional heat so that the bonding process is improved. These effects give By the way also in the versions the invention in which the transmission parts no thread or a thread-like structure exhibit.
