Description

Die vorliegende Erfindung betrifft die Lagerung von einem Zapfen, vorzugsweise ein Kurbelwellenhauptlager, gemäß den Merkmalen der aufgeführten Ansprüche.The The present invention relates to the storage of a pin, preferably a crankshaft main bearing, according to the features the listed Claims.

Kurbelwellenlagerungen sind vornehmlich gleitgelagert. Diese Art der Lagerungen generieren eine gewisse Reibungsarbeit.crankshaft bearings are mainly sliding. This type of storage generates one certain friction work.

Um zukünftige Forderungen bezüglich Verbrauch und Emissionen zu erreichen, müssen weitere Maßnahmen auch an der mechanischen Einheit des Motors angegangen werden. Eine dieser Maßnahmen ist die Wälzlagerung der Kurbelwelle in dem Motorblock. Die Wälzlagerungen leiten die periodischen Kontaktkräfte dynamisch an die Blockstruktur und damit nach außen. Diese sind störend und müssen vermieden werden.Around future Claims regarding To achieve consumption and emissions, further measures must be taken also be addressed at the mechanical unit of the engine. A of these measures is the rolling bearing the crankshaft in the engine block. The rolling bearings conduct the periodic contact forces dynamically to the block structure and thus to the outside. These are disturbing and have to be avoided.

Gelöst wird dieses Problem bisher mit der Anpassung der Strukturform der äußeren Blockstruktur um diese akustischen Anregungen abzukapseln.Is solved this problem so far with the adaptation of the structural shape of the outer block structure to encapsulate these acoustic suggestions.

Der Erfindung liegt nun die Aufgabe zu Grunde, diese akustischen Nachteile aus der Welt zu schaffen.Of the Invention is now based on the object, these acoustic disadvantages to get out of the world.

Diese Aufgabe wird gemäß der Erfindung dadurch gelöst, indem zwischen den Wälzkörpern und der Blockhauptlagerbohrung ein Aufnahmering zur Anwendung kommt. Dieser Aufnahmering kann gleichzeitig als Außenring des Wälzlagers ausgeführt werden, ist jedoch stärker in der radialen Ausdehnung ausgeführt. Dieser Aufnahmering ist geteilt ausgeführt (vorzugsweise bruchgetrennt) und nach Montage wieder verschraubt.These Task is according to the invention solved by by between the rolling elements and the Block main bearing bore a receiving ring is used. This Retaining ring can simultaneously as outer ring of the rolling bearing be executed is stronger executed in the radial extension. This recording ring is split executed (preferably fracture-separated) and bolted again after installation.

Aus der Literatur ist die Nutzung solcher Aufnahmeringe für die Umsetzung der variablen Verdichtung bekannt. In diesem Fall ist die innere Aufnahmebohrung gegenüber dem äußeren Durchmesser exzentrisch gelagert. Weiter sind diese Aufnahmeringe miteinander verbunden. Durch Schwenken dieser verbundenen Ringe erfolgt eine Verschiebung der Kurbelwelle und des Kolbens und somit eine Veränderung des Verdichtungsverhältnisses.Out The literature is the use of such recording rings for the implementation the variable compression known. In this case, the inner one Receiving bore opposite the outer diameter stored eccentrically. Next, these recording rings are together connected. By pivoting these connected rings is a Displacement of the crankshaft and the piston and thus a change the compression ratio.

Die Vorteile der Wälzlagerung des Kurbeltriebs und die variable Verdichtung sind addierbar und bergen große Vorteile für den Verbrennungsmotor.The Advantages of rolling bearing of the crank mechanism and the variable compression are addable and hold big Benefits for the internal combustion engine.

Die Erfindung wird anhand schematischer Zeichnungen näher erläutert. Es zeigen:The The invention will be explained in more detail with reference to schematic drawings. It demonstrate:

1: die Lagerstelle der Kurbelwelle im Block mit konzentrische Positionierung 1 : the bearing point of the crankshaft in the block with concentric positioning

2: die Lagerstelle der Kurbelwelle im Block mit exzentrischer Positionierung 2 : the bearing point of the crankshaft in the block with eccentric positioning

Die schematische Darstellung 1 zeigt den zweiteilig verschraubten Aufnahmering (1), welche die Wälzkörper (3) mit dem dazugehörigen Laufkäfig aufnimmt. Die Wälzkörper (3) laufen direkt auf dem Wellenzapfen (2') der Kurbelwelle (2). Die Kurbelwelle (2) läuft konzentrisch zum Außendurchmesser des Aufnahmeringes (1). Die Außenfläche des Aufnahmeringes (1) ist in der Blockbohrung aufgenommen. Der Aufnahmering (1) ist vorzugsweise bruchgetrennt, so dass die Lauffläche für die Wälzkörper (vorzugsweise Zylinderrollen) keine gerade Trennfuge darstellt.The schematic representation 1 shows the two-part screwed receiving ring ( 1 ), which the rolling elements ( 3 ) receives with the associated Laufkäfig. The rolling elements ( 3 ) run directly on the shaft journal ( 2 ' ) of the crankshaft ( 2 ). The crankshaft ( 2 ) runs concentrically with the outer diameter of the receiving ring ( 1 ). The outer surface of the receiving ring ( 1 ) is received in the block bore. The receiving ring ( 1 ) is preferably fracture-separated, so that the running surface for the rolling elements (preferably cylindrical rollers) is not a straight parting line.

Die beiden Hälften des Aufnahmeringes werden an geeigneter Stelle mit geeigneten Mitteln, vorzugsweise Schrauben, miteinander verbunden.The both halves of the receiving ring shall be provided at an appropriate place by appropriate means, preferably screws, connected together.

Die schematische Darstellung 2 zeigt den Aufnahmering (1) mit der exzentrischen Aufnahmebohrung für die wälzgelagerte Kurbelwelle.The schematic representation 2 shows the recording ring ( 1 ) with the eccentric receiving bore for the roller bearing crankshaft.
