Description
Die Erfindung betrifft ein Schwungrad, eine Reibungskupplung und ein Zweimassenschwungrad nach den Oberbegriffen der unabhängigen Ansprüche.The invention relates to a flywheel, a friction clutch and a dual mass flywheel according to the preambles of the independent claims.
Ein Schwungrad mit Fliehkraftpendeln, die jeweils zwei Pendelhälften umfassen, ist beispielsweise aus der
Weiterhin werden als Stand der Technik die
Eine Aufgabe der vorliegenden Erfindung ist es daher, die Tragfähigkeit des Fliehkraftpendels zu erhöhen.An object of the present invention is therefore to increase the carrying capacity of the centrifugal pendulum.
Die Aufgabe wird durcch die Merkmale der Ansprüche 1, 11 und 12 gelöst.The object is achieved by the features of
Dieses Problem wird gelöst durch ein Schwungrad mit mindestens einem Fliehkraftpendel, das zwei Pendelhälften umfasst, die beiderseits einer Trägerplatte angeordnet sind und mit mindestens einem Führungsmittel, das in einer Führungsbahn der Trägerplatte beweglich gelagert ist, drehbar gegenüber der Trägerplatte gelagert ist, wobei das Führungsmittel mindestens einen Wälzkörper umfasst.This problem is solved by a flywheel with at least one centrifugal pendulum, which comprises two pendulum halves, which are arranged on both sides of a support plate and is rotatably mounted with at least one guide means which is movably mounted in a guide track of the support plate relative to the support plate, wherein the guide means at least comprises a rolling element.
Mit dieser Maßnahme wird neben der Lösung des oben genannten Problems eine Reduzierung der Anzahl der zu montierenden Teile erreicht. Dies vereinfacht dabei auch die Montage. Mit der erfindungsgemäßen Lösung wird zudem eine Erhöhung der Fertigungsgenauigkeit erreicht. Bei einer Pendelbewegung der Fliehkraftpendel wird die Reibung reduziert, sodass auch eine geringere Geräuschentwicklung eintritt. Der geringere Fertigungsaufwand reduziert zudem die Fertigungskosten. With this measure, in addition to the solution of the above problem, a reduction in the number of parts to be assembled is achieved. This also simplifies the assembly. With the solution according to the invention also an increase in manufacturing accuracy is achieved. With a pendulum motion of the centrifugal pendulum, the friction is reduced, so that less noise occurs. The lower production costs also reduce the production costs.
Vorzugsweise ist vorgesehen, dass die beiden Pendelhälften Teil eines einstückig gefertigten Sattelpendels sind, welches vorzugsweise aus einem Blech durch Stanzbiegen hergestellt ist.It is preferably provided that the two pendulum halves are part of an integrally manufactured saddle pendulum, which is preferably made of a metal sheet by stamping.
Vorzugsweise ist vorgesehen, dass der Wälzkörper ein Lageraußenring eines Wälzlagers ist. Der Wälzkörper ist vorzugsweise an einem Bolzen, der zwischen den Pendelhälften angeordnet ist, angeordnet. Vorzugsweise ist vorgesehen, dass der Bolzen mit den Pendelhälften verpresst ist.It is preferably provided that the rolling element is a bearing outer ring of a roller bearing. The rolling element is preferably arranged on a bolt which is arranged between the pendulum halves. It is preferably provided that the bolt is pressed with the pendulum halves.
Wälzkörper des Wälzlagers rollen vorzugsweise auf dem Bolzen zur Verbindung der Pendelhälften.Rolling elements of the rolling bearing preferably roll on the bolt for connecting the pendulum halves.
Vorzugsweise ist vorgesehen, dass die Führungsbahn der Trägerplatte durch einen Einsatz, der in einer Öffnung der Trägerplatte angeordnet ist, gebildet wird. Härte, Oberflächenqualität und dergleichen des Einsatzes können unabhängig von den Werten der Trägerplatte definiert werden.It is preferably provided that the guide track of the carrier plate is formed by an insert which is arranged in an opening of the carrier plate. Hardness, surface quality and the like of the insert can be defined independently of the values of the support plate.
Vorzugsweise ist vorgesehen, dass der Einsatz ein gezogenes Bauteil aus Stahlblech ist. Die Rauigkeit eines gezogenen Bauteils ist geringer als die einer gestanzten Oberfläche, sodass dies die Reibung und damit den Verschleiß verringert.It is preferably provided that the insert is a drawn component made of sheet steel. The roughness of a drawn component is less than that of a stamped surface, which reduces friction and thus wear.
Vorzugsweise ist vorgesehen, dass der Einsatz zumindest an der Oberfläche, die mit dem Wälzkörper in Kontakt ist, gehärtet ist. Dadurch wird der Verschleiß weiter verringert.It is preferably provided that the insert is hardened at least on the surface which is in contact with the rolling body. This further reduces wear.
Vorzugsweise ist vorgesehen, dass der Lageraußenring ballig geformt ist. Dadurch können Winkelfehler ausgeglichen werden.It is preferably provided that the bearing outer ring is spherically shaped. As a result, angle errors can be compensated.
Die beiden Pendelhälften wurden erfindungsgemäß durch ein Sattelpendel ersetzt. Dadurch kann auf die Nietverbindungen zwischen den Pendelhälften verzichtet werden. Die zylindrischen Führungsbolzen wurden in das Sattelpendel eingepresst. Auf den Bolzen befinden sich vollnadelige Stützrollen, die das Pendel in der Trägerplatte führen. Der gehärtete Außenring der Stützrollen ist leicht ballig und somit unempfindlich gegenüber Verkippung bzw. Bolzenschiefstellung. In die gestanzten nierenförmigen Bohrungen der Trägerplatte wurden gezogene und gehärtete Einsätze eingepresst. Die Ziehteile weisen eine sehr hohe Oberflächenqualität und insbesondere einen hohen Traganteil auf im Vergleich zu gestanzten Oberflächen, was sich positiv auf die Tragfähigkeit des Pendels auswirkt. Darüber hinaus kann auf die Wärmebehandlung des Pendels und der Trägerplatte verzichtet werden, weil kein direkter Hertzscher Kontakt zu Stützrollen vorliegt.The two pendulum halves were replaced according to the invention by a saddle pendulum. As a result, can be dispensed with the rivet connections between the pendulum halves. The cylindrical guide pins were pressed into the saddle pendulum. On the bolt are full-needle support rollers that guide the pendulum in the carrier plate. The hardened outer ring of the support rollers is slightly convex and thus insensitive to tilting or bolt misalignment. Pulled and hardened inserts were pressed into the punched kidney-shaped holes of the carrier plate. The drawn parts have a very high surface quality and, in particular, a high percentage of support compared to stamped surfaces, which has a positive effect on the bearing capacity of the pendulum. In addition, can be dispensed with the heat treatment of the pendulum and the support plate, because there is no direct Hertzian contact with support rollers.
Das eingangs genannte Problem wird auch gelöst durch ein Sattelpendel zur Verwendung an einem Schwungrad nach einem der vorhergehenden Ansprüche, wobei die beiden Pendelhälften Teil eines einstückig gefertigten Sattelpendels sind, wobei das Sattelpendel aus einem Blech durch Stanzbiegen hergestellt ist.The aforementioned problem is also solved by a saddle pendulum for use on a flywheel according to one of the preceding claims, wherein the two pendulum halves part an integrally manufactured saddle pendulum, wherein the saddle pendulum is made of a metal sheet by stamping.
