Die Erfindung betrifft einen Zylinderkopf für eine Brennkraftmaschine, mit einem gemeinsamen Nockenwellenlagerdeckel für zwei parallel zueinander angeordnete Nockenwellen, wobei im Nockenwellenlagerdeckel eine Ölkanalanordnung und eine Aufnahmebohrung für ein hydraulisches Steuerventil angeordnet ist.The invention relates to a cylinder head for an internal combustion engine, with a common camshaft bearing cap for two parallel camshafts, wherein in the camshaft bearing cap an oil passage assembly and a receiving bore for a hydraulic control valve is arranged.
Aus der EP 1 316 682 B2 ist ein Zylinderkopf für eine Brennkraftmaschine mit einem für zwei parallel angeordnete Nockenwellen gemeinsam ausgebildeten Nockenwellenlagerdeckel bekannt, wobei in Durchgangsbohrungen des Nockenwellenlagerdeckels jeweils ein hydraulisches Steuerventil angeordnet ist, welches den Nockenwellenlagerdeckel durchdringt und in einer Sackbohrung des Zylinderkopfes mündet. Das Öl gelangt dabei über Zuflussbohrungen im Zylinderkopf und Ölfilter zum Steuerventil und wird über die Ölkanalanordnung zu den Nockenwellenlagern geleitet.From EP 1 316 682 B2, a cylinder head for an internal combustion engine with a camshaft bearing cover designed in parallel for two camshafts is known, wherein in each case a hydraulic control valve is arranged in through bores of the camshaft bearing cap, which penetrates the camshaft bearing cap and opens into a blind bore of the cylinder head. The oil passes through inflow holes in the cylinder head and oil filter to the control valve and is passed through the oil passage assembly to the camshaft bearings.
Aufgabe der Erfindung ist es, auf möglichst einfache Weise eine Schmierölversorgung zu den Kipphebelachslagern und dem hydraulischen Steuerventil zu ermöglichen.The object of the invention is to enable the simplest possible way a supply of lubricating oil to the Kipphebelachslagern and the hydraulic control valve.
Erfindungsgemäß wird dies dadurch erreicht, dass die Ölkanalanördnung durch Bohrungen gebildet ist, wobei im Nockenwellenlagerdeckel zumindest eine Zuflussbohrung und zumindest eine Ölquerverteilungsbohrung angeordnet ist, welche zumindest eine zu einer Kipphebelachslagerung führende Versorgungsbohrung mit der Zuflussbohrung strömungsverbindet, wobei vorzugsweise die Aufnahmebohrung für das hydraulische Steuerventil über einen Verbindungsbohrung mit der Ölquerverteilungsbohrung verbunden ist. Über die Ölquerverteilungsbohrung können somit die Kipphebelachslager und das hydraulische Steuerventil mit Öl versorgt werden. Dadurch, dass die Ölkanalanordnung durch einzelne Bohrungen gebildet ist, kann eine einfache Fertigung ermöglicht werden.According to the invention this is achieved in that the Ölkanalanördnung is formed by holes, wherein at least one inflow bore and at least one Ölquerverteilungsbohrung is arranged in the camshaft bearing cap, which connects at least one leading to a Kipphebelachslagerung supply bore with the inflow bore, wherein preferably the receiving bore for the hydraulic control valve via a Connecting hole is connected to the oil cross distribution hole. Thus, the rocker arm bearing and the hydraulic control valve can be supplied with oil via the oil transverse distribution bore. The fact that the oil passage arrangement is formed by individual holes, a simple production can be made possible.
Vorteilhafterweise ist dabei vorgesehen, dass die Ölquerverteilungsbohrung sich im Wesentlichen zwischen einem einlassseitigen und einem auslassseitigen Nockenwellenlager erstreckt.Advantageously, it is provided that the oil transverse distribution bore extends substantially between an inlet-side and an outlet-side camshaft bearing.
Sowohl die Ölquerverteilungsbohrung, als auch die Aufnahmebohrung für das hydraulische Steuerventil sind als Sackbohrungen ausgebildet.Both the oil lateral distribution bore and the receiving bore for the hydraulic control valve are designed as blind bores.
Weiters kann vorgesehen sein, dass zumindest eine Versorgungsbohrung für eine Kipphebelachslagerung als Durchgangsbohrung ausgebildet ist.Furthermore, it can be provided that at least one supply hole for a Kipphebelachslagerung is formed as a through hole.

Die Erfindung wird im folgenden anhand der Fig. näher erläutert.The invention will be explained in more detail below with reference to FIG.
Die Fig. zeigt einen gemeinsamen Nockenwellenlagerdeckel 1 für zwei im Zylinderkopf angeordnete Nockenwellen, wobei die Nockenwellenlager mit Bezugszeichen 2 und 3 bezeichnet sind. Der Nockenwellenlagerdeckel 1 bildet darüber hinaus auch die Kipphebelachslager 4, 5 aus. Im Nockenwellenlagerdeckel 1 ist eine Ölkanalanordnung 6 vorgesehen, welche eine Zuflussbohrung 7, eine Ölquerverteilungsbohrung 8 und zu dem Kipphebelachslagerungen 4, 5 führende Versorgungsbohrungen 9, 10 aufweist.FIG. 1 shows a common camshaft bearing cap 1 for two camshafts arranged in the cylinder head, wherein the camshaft bearings are designated by reference numbers 2 and 3. The camshaft bearing cap 1 also forms the Kipphebelachslager 4, 5 from. In the camshaft bearing cap 1, an oil passage arrangement 6 is provided, which has an inflow bore 7, an oil transverse distribution bore 8 and to the Kipphebelachslagerungen 4, 5 leading supply holes 9, 10.
Die Ölzuführbohrung 7 und die Öiquerverteilungsbohrung 8 sind als Sackbohrungen ausgebildet, wobei die Öiquerverteilungsbohrung 6 von einer Seite 11 des Nockenwellenlagerdeckels 1 ausgeht. Die Öiquerverteilungsbohrung 8 ist nachträglich mit einem Stoppel 12 verschlossen.The oil feed hole 7 and the oil distribution hole 8 are formed as blind holes, the oil distribution hole 6 extending from one side 11 of the camshaft bearing cap 1. The oil distribution hole 8 is subsequently closed with a stubble 12.
Die Ölzuflussbohrung 7 steht mit einem nicht weiter dargestellten Ölversorgungskanal des Zylinderkopfes in Verbindung.The Ölzuflussbohrung 7 communicates with a not shown oil supply channel of the cylinder head in conjunction.
Weiters weist der Nockenwellenlagerdeckel 1 eine Aufnahmebohrung 13 für ein hydraulisches Steuerventil auf, wobei die Aufnahmebohrung 13 über eine Verbindungsbohrung 15 mit der Öiquerverteilungsbohrung 8 verbunden ist. Die Versorgungsbohrungen 9, 10 und die Ölverteilbohrung 15, sowie die Zuflussbohrung 7 sind im Wesentlichen quer zur Öiquerverteilungsbohrung 8 angeordnet.Furthermore, the camshaft bearing cap 1 has a receiving bore 13 for a hydraulic control valve, wherein the receiving bore 13 is connected via a connecting bore 15 with the Öibererverteilungsbohrung 8. The supply holes 9, 10 and the oil distribution hole 15, and the inflow bore 7 are arranged substantially transversely to the oil distribution hole 8.
Diese Ausbildung erlaubt eine einfache Fertigung und gestattet es, mit geringem Aufwand sowohl die Kipphebelachslager als auch das hydraulische Steuerventil mit Öl zu versorgen.This design allows for easy production and allows to supply both the Kipphebelachslager and the hydraulic control valve with little effort with oil.
