Description
Die Erfindung betrifft eine Stellvorrichtung nach dem Oberbegriff des Anspruchs 1.The invention relates to an adjusting device according to the preamble of claim 1.
Aus der
Der Erfindung liegt insbesondere die Aufgabe zugrunde, eine Lebensdauer der Stellvorrichtung vorteilhaft zu verlängern. Sie wird gemäß der Erfindung durch die Merkmale des Anspruchs 1 gelöst. Weitere Ausgestaltungen ergeben sich aus den Unteransprüchen.The invention is in particular the object of extending a lifetime of the adjusting device advantageous. It is achieved according to the invention by the features of claim 1. Further embodiments emerge from the subclaims.
Die Erfindung geht aus von einer Stellvorrichtung für eine Brennkraftmaschinenventiltriebvorrichtung, insbesondere einer Nockenwellenverstellvorrichtung für ein Kraftfahrzeug, mit einer Phaseneinstelleinheit zur Einstellung einer Phasenlage einer Welle, mit einer Deckeleinheit, die zumindest ein erstes Verbindungselement aufweist, mit einem Federhaus, das zumindest ein zu dem zumindest einen ersten Verbindungselement korrespondierendes zweites Verbindungselement aufweist, wobei die zumindest zwei Verbindungselemente eine Primärkontur aufweisen, die dazu vorgesehen ist, eine formschlüssige Verbindung zwischen dem Federhaus und der Deckeleinheit herzustellen.The invention is based on an adjusting device for an internal combustion engine valve drive device, in particular a camshaft adjusting device for a motor vehicle, with a phase adjustment unit for adjusting a phase position of a shaft, with a cover unit having at least a first connecting element, with a barrel that at least one of the at least one first connecting element corresponding second connecting element, wherein the at least two connecting elements have a primary contour, which is intended to produce a positive connection between the barrel and the cover unit.
Es wird vorgeschlagen, dass wenigstens eines der Verbindungselemente zumindest eine Sekundärkontur aufweist, die dazu vorgesehen ist, die formschlüssige Verbindung der Primärkontur zu ergänzen. Dadurch kann eine feste Verbindung zwischen Federhaus und Deckeleinheit verstärkt werden, wodurch Vibrationen und ruckartige Bewegungen des Federhauses vermieden und die daraus entstehenden Schäden vorteilhaft verringert werden können. Dadurch kann eine Lebensdauer der Stellvorrichtung vorteilhaft verlängert werden. Unter einer „Kontur” soll in diesem Zusammenhang eine formschlüssige Verbindung der zwei korrespondierenden Verbindungselemente verstanden werden, die vorteilhafterweise entlang zumindest einer Raumrichtung überlappend angeordnet sind. Unter einem Verbindungselement soll insbesondere ein, eine positive Teilkontur oder ein, eine negative Teilkontur ausbildendes Bauteil verstanden werden. Vorzugsweise greifen die Verbindungselemente in einem montierten Zustand vollständig ineinander ein. Unter einer „eine Primärkontur ergänzende Sekundärkontur” soll insbesondere verstanden werden, dass wenigstens eines der Verbindungselemente zur Ausbildung zweier unterschiedlicher Teilkonturen vorgesehen ist. Unter unterschiedlichen Teilkonturen sollen dabei insbesondere zumindest zwei Teilkonturen verstanden werden, die zur Ausbildung von unterschiedlichen Wirkrichtungen vorgesehen sind.It is proposed that at least one of the connecting elements has at least one secondary contour, which is provided to supplement the positive connection of the primary contour. As a result, a firm connection between the barrel and the lid unit can be reinforced, whereby vibrations and jerky movements of the barrel avoided and the resulting damage can be advantageously reduced. As a result, a life of the adjusting device can be advantageously extended. In this context, a "contour" is to be understood to mean a form-locking connection of the two corresponding connecting elements, which are advantageously arranged overlapping along at least one spatial direction. A connection element is to be understood as meaning, in particular, a component forming a positive subcontour or a component forming a negative subcontour. Preferably, the connecting elements fully engage in one another in an assembled state. A "secondary contour that supplements a primary contour" should be understood in particular to mean that at least one of the connecting elements is provided for the purpose of forming two different subcontours. In this context, different partial contours should be understood to mean, in particular, at least two partial contours, which are provided for the purpose of forming different effective directions.
Weiter wird vorgeschlagen, dass wenigstens eines der Verbindungselemente zumindest in vormontiertem Zustand sekundärkonturfrei ist. Dadurch können die Verbindungselemente besonders einfach gefertigt werden. Unter „sekundärkonturfrei” soll dabei insbesondere verstanden werden, dass ein zweites Verbindungselement, das als eine Verbindungslasche ausgebildet ist, eine Auflagefläche aufweist, die in dem vormontierten Zustand als eine ebene Fläche ausgebildet ist. Unter einer „Auflagefläche” soll hierbei die Fläche des Verbindungselements verstanden werden, die dazu vorgesehen ist, mit dem ersten Verbindungselement in Kontakt zu stehen.It is further proposed that at least one of the connecting elements is at least secondary-contour-free in the preassembled state. As a result, the connecting elements can be manufactured particularly easily. By "secondary contour free" is to be understood in particular that a second connecting element, which is designed as a connecting strap, has a bearing surface, which is formed in the pre-assembled state as a flat surface. A "bearing surface" is to be understood here as the surface of the connecting element which is intended to be in contact with the first connecting element.
Ferner wird vorgeschlagen, dass in dem montierten Zustand die Sekundärkontur des zumindest einen ersten Verbindungselements und die Sekundärkontur des zumindest einen zweiten Verbindungselements formschlüssig ineinander greifen. Dadurch kann eine Verbindung zwischen dem Federhaus und der Deckeleinheit besonders einfach verstärkt werden.It is also proposed that in the mounted state, the secondary contour of the at least one first connecting element and the secondary contour of the at least one second connecting element engage in one another in a form-fitting manner. As a result, a connection between the barrel and the lid unit can be particularly easily reinforced.
Des Weiteren wird vorgeschlagen, dass die Primärkontur und die Sekundärkontur dazu vorgesehen sind, in einem gemeinsamen Umformverfahrensschritt in Eingriff gebracht zu werden. Dadurch kann das Federhaus besonders vorteilhaft und einfach in einem Montageschritt mit der Deckeleinheit verbunden werden. Unter einem „Umformverfahrensschritt” soll dabei insbesondere ein Umbiegen des zumindest einen zweiten Verbindungselements um die Deckeleinheit verstanden werden.Furthermore, it is proposed that the primary contour and the secondary contour are intended to be engaged in a common forming process step. Thereby, the barrel can be particularly advantageous and easily connected in an assembly step with the cover unit. A "forming process step" should be understood to mean, in particular, a bending over of the at least one second connecting element about the cover unit.
Außerdem wird vorgeschlagen, dass die Sekundärkontur des zumindest einen zweiten Verbindungselements mittels des Umformverfahrensschritts eingebracht ist. Dadurch kann eine besonders vorteilhafte und feste Verbindung zwischen dem Federhaus und der Deckeleinheit erreicht werden.It is also proposed that the secondary contour of the at least one second connecting element is introduced by means of the forming process step. This allows a particularly advantageous and firm connection between the barrel and the cover unit can be achieved.
Weiter wird vorgeschlagen, dass das Federhaus und die Deckeleinheit durch die formschlüssige Verbindung der Verbindungselemente mittels der Sekundärkontur zumindest in radialer Richtung fest verbunden sind. Dadurch können die Vibrationen und ruckartigen Bewegungen des Federhauses besonders gut unterbunden werden. Unter einer „radialen Richtung” soll in diesem Zusammenhang insbesondere die Radialrichtung, ausgehend von der Hauptrotationsachse der Stellvorrichtung, verstanden werden.It is further proposed that the barrel and the cover unit are firmly connected by the positive connection of the connecting elements by means of the secondary contour at least in the radial direction. As a result, the vibrations and jerky movements of the barrel can be particularly well prevented. Under a "radial Direction "should be understood in this context, in particular the radial direction, starting from the main axis of rotation of the adjusting device.
Ferner wird vorgeschlagen, dass die Sekundärkontur in dem zumindest einen ersten Verbindungselement zumindest eine axiale Vertiefung ausbildet. Dadurch kann die Sekundärkontur fertigungstechnisch besonders einfach in das Verbindungselement eingebracht werden. Unter einer „axialen Vertiefung” in dem ersten Verbindungselement soll hierbei insbesondere eine, in eine Auflagefläche des zumindest einen ersten Verbindungselements eingebrachte Vertiefung verstanden werden. Die Auflagefläche weist dabei vorzugsweise eine parallel zur Hauptrotationsachse orientierte Flächennormale auf.It is also proposed that the secondary contour in the at least one first connecting element forms at least one axial recess. As a result, the secondary contour can be introduced in a particularly simple manner into the connecting element in terms of manufacturing technology. An "axial depression" in the first connection element is to be understood here in particular as a depression introduced into a support surface of the at least one first connection element. The support surface preferably has a surface normal oriented parallel to the main axis of rotation.
Des Weiteren wird vorgeschlagen, dass die Sekundärkontur in dem zumindest einen zweiten Verbindungselement wenigstens eine axiale Erhöhung ausbildet. Dadurch kann das zumindest eine erste Verbindungselement und das zumindest eine zweite Verbindungselement besonders einfach in eine formschlüssige Verbindung gebracht werden. Unter einer „axialen Erhöhung” in dem zweiten Verbindungselement soll dabei insbesondere eine, aus einer Auflagefläche des zumindest einen zweiten Verbindungselements herausstehende Erhöhung verstanden werden. Die Auflagefläche weist dabei vorzugsweise eine parallel zur Hauptrotationsachse orientierte Flächennormale auf.Furthermore, it is proposed that the secondary contour in the at least one second connecting element forms at least one axial elevation. As a result, the at least one first connecting element and the at least one second connecting element can be brought into a positive connection in a particularly simple manner. An "axial elevation" in the second connecting element should be understood to mean, in particular, an elevation projecting from a bearing surface of the at least one second connecting element. The support surface preferably has a surface normal oriented parallel to the main axis of rotation.
