Description
Die Erfindung betrifft ein Zweimassenschwungrad nach dem Oberbegriff des Anspruchs 1.The invention relates to a dual mass flywheel according to the preamble of
Zweimassenschwungräder sind aus dem Stand der Technik, beispielsweise aus der
Oftmals wird eine Eingriffsgeometrie im Außenbereich der Primärseite zur Handhabung der Bauteile im Rahmen der Fertigung oder zum Durchdrehen des gesamten Verbrennungsmotors beim sogenannten Kalttest als Handhabungseingriff benötigt. In vielen Fällen wird der vorhandene gehärtete oder ungehärtete und umlaufend verzahnte Anlasskranzdazu verwendet. Ist kein Anlasserzahnkranz vorhanden werden separate Bauteile, deren einziger Zweck darin besteht, die für den Kalttest notwendigen Eingriffsgeometrien bereitzustellen, verwendet.
Eine Aufgabe der Erfindung ist es daher, eine einfache und kostengünstige Umsetzung eines Handhabungseingriffs bei einem Zweimassenschwungrad anzugeben.Often an engagement geometry in the outer area of the primary side is required for handling the components during production or for cranking the entire internal combustion engine during the so-called cold test as a handling intervention. In many cases the existing hardened or unhardened and circumferentially toothed starting ring is used for this. If there is no starter ring gear, separate components are used, the sole purpose of which is to provide the meshing geometries required for the cold test.
It is therefore an object of the invention to provide a simple and inexpensive implementation of a handling intervention in a dual mass flywheel.
Dieses Problem wird durch ein Zweimassenschwungrad nach Anspruch 1 gelöst. Bevorzugte Ausführungsformen, Ausgestaltungen oder Weiterbildungen der Erfindung sind in den abhängigen Ansprüchen angegeben.This problem is solved by a dual mass flywheel according to
Das oben genannte Problem wird insbesondere gelöst durch ein Zweimassenschwungrad mit einer Primärseite und einer Sekundärseite, die um eine gemeinsame Rotationsachse gegen ein Rückstellmoment einer Bogenfeder relativ zueinander verdrehbar sind, wobei die Primärseite ein Primärmassenblech und einen Primärmassendeckel umfasst, wobei das Primärmassenblech und/oder der Primärmassendeckel einen Handhabungseingriff für einen temporären externen Antrieb aufweist.The above-mentioned problem is solved in particular by a dual-mass flywheel with a primary side and a secondary side, which can be rotated relative to one another about a common axis of rotation against a restoring torque of an arc spring, the primary side comprising a primary mass plate and a primary mass cover, the primary mass plate and / or the primary mass cover has a handling engagement for a temporary external drive.
Der Primärmassendeckel weist in einer Ausführungsform der Erfindung einen zweilagigen Blechbereich auf, in dem der Handhabungseingriff eingebracht ist. Der Primärmassendeckel umfasst dazu vorzugsweise einen Innengurt und einen Außengurt, wobei der Handhabungseingriff in den Außengurt eingebracht ist. Durch Umlegen eines äußeren Bereichs der Platine, dies ist das Rohteil des Primärmassenblechs, können Außen- und Innengurt leicht gefertigt werden.
Die Eingriffe sind werkzeugfallend bereits in der Platine des Primärmassenblechs gestanzt und werden anschließend beim Formgeben des Außenbereichs mit umgelegt Der Handhabungseingriff weist in einer Ausführungsform der Erfindung Zähne und Zahnlücken in dem Außengurt auf, die in Richtung der dem Primärmassenblech abgewandten Seite geöffnet sind. Die Zähne und Zahnlücken können dadurch in den Außenrand der Platine des Primärmassenflansches gestanzt werden.
Innengurt und Außengurt überdecken das Primärmassenblech vorzugsweise zumindest teilweise in axialer Richtung. Dies spart axialen Bauraum bei nur unwesentlich größerem radialem Bauraum.In one embodiment of the invention, the primary mass cover has a two-layer sheet metal area in which the handling engagement is introduced. For this purpose, the primary mass cover preferably comprises an inner belt and an outer belt, the handling engagement being made in the outer belt. Outer and inner belts can be easily manufactured by turning over an outer area of the board, which is the raw part of the primary mass plate.
The interventions are already punched in the plate of the primary mass plate without the need for a tool and are then folded over when the outer area is shaped. The teeth and tooth gaps can thereby be punched into the outer edge of the plate of the primary mass flange.
The inner belt and the outer belt preferably cover the primary mass plate at least partially in the axial direction. This saves axial installation space with only an insignificantly larger radial installation space.
Das Primärmassenblech weist in einer alternativen Ausführungsform der Erfindung einen zweilagigen Blechbereich auf, in dem der Handhabungseingriff eingebracht ist. Das Primärmassenblech umfasst dabei vorzugsweise einen Innengurt und einen Außengurt, wobei der Handhabungseingriff in den Außengurt eingebracht ist. Durch Umlegen eines äußeren Bereichs der Platine des Primärmassendeckels, dies ist das Rohteil des Primärmassendeckels, können Außen- und Innengurt leicht gefertigt werden.In an alternative embodiment of the invention, the primary mass plate has a two-layer plate area in which the handling engagement is introduced. The primary mass plate preferably comprises an inner belt and an outer belt, the handling engagement being made in the outer belt. By turning over an outer area of the circuit board of the primary mass cover, this is the raw part of the primary mass cover, the outer and inner belts can be easily manufactured.
Der Handhabungseingriff weist in einer Ausführungsform der Erfindung Zähne und Zahnlücken in dem Außengurt auf, die in Richtung der dem Primärmassendeckel abgewandten Seite geöffnet sind. Die Zähne und Zahnlücken können dadurch in den Außenrand der Platine des Primärmassenflansches gestanzt werden.In one embodiment of the invention, the handling engagement has teeth and tooth gaps in the outer belt which are open in the direction of the side facing away from the primary mass cover. The teeth and tooth gaps can thereby be punched into the outer edge of the plate of the primary mass flange.
Der Außengurt wird in einer Ausführungsform der Erfindung zumindest teilweise in axialer Richtung durch einen Außendeckel des Primärmassendeckels überdeckt. Dadurch wird die Festigkeit erhöht und eine Vorzentrierung von Primärmassendeckel und Primärmassenblech beim Verschweißen bewirkt.In one embodiment of the invention, the outer belt is at least partially covered in the axial direction by an outer cover of the primary mass cover. This increases the strength and causes the primary mass cover and primary mass plate to be pre-centered during welding.
Der Außengurt weist in einer Ausführungsform der Erfindung eine Anprägung zur Aufnahme des Außendeckels auf. Dadurch kann der radiale Bauraum verkleinert werden.In one embodiment of the invention, the outer belt has an embossing for receiving the outer cover. As a result, the radial installation space can be reduced.
