    • The invention relates to a variable valve train for internal combustion engines for actuating gas exchange valves which can be operated set to different opening lifts. The aim of the invention is to provide a variable valve train for actuating gas exchange valves of internal combustion engines, characterised by having a simple structure whilst at the same time reducing exerted frictional forces. The claimed valve train for internal combustion engines for actuating gas exchange valves consists of a camshaft driven by a crankshaft of the internal combustion engine, said camshaft consisting of several individual cam sleeves which can be displaced axially against each other. The individual cam sleeves which be displaced separately against each other are connected via an axially extending toothing, said toothing of the respective adjacent cam sleeves being embodied in an engaging manner. Several different cam profiles with similar base-circle sections are arranged on each cam sleeve, said base-circle sections can be brought into contact with the gas exchange valves by displacing the individual cam sleeves. A selector shaft rotating with the cam sleeves is arranged inside the cam sleeves, said selector shaft being operatively connected to the respective cam sleeve via a shifting mechanism. Said shifting mechanisms are mounted respectively in a fixed manner in each cam sleeve and in a sliding manner in a shifting contour arranged on the selector shaft. Said selector shaft is connected to a displacement part which can be displaced axially and which is also rotationally fixed on the cam sleeve by means of the shifting mechanism. An actuator which is fixed to the housing of the internal combustion engine can be operatively connected to the displacement part for producing a relative rotation of the selector shaft in relation to the cam sleeve.

The aim of the invention is to provide a valve train for actuating gas exchange valves of internal combustion engines, characterised by having a simple structure whilst at the same time reducing exerted frictional forces. The claimed valve train for actuating the gas exchange valves comprises a tubular-shaped camshaft which can be driven by a crankshaft of the internal combustion engine. One or more rotationally fixed but axially displaceable cam supports are arranged on the camshaft pipe, which respectively have the same base-circle section with several different cam profiles. The cam profiles can be operatively connected to the gas exchange valves by displacing the cam support. The cam support is displaced on a camshaft pipe for controlling the valve by means of a selector shaft arranged inside the camshaft pipe and rotating with said camshaft pipe which is operatively connected to a cam support which can be axially displaced on the camshaft pipe by means of a driver which slides in a selector contour on the selector shaft. Said selector shaft is connected to a rotationally fixed but axially displaceable displacement part on the cam sleeve by means of a transmission, said displacement part being operatively connected to the actuator for producing a relative rotation of the camshaft in relation to the camshaft pipe in order to actuate the selector shaft.

    • The invention relates to a valve drive for internal combustion engines, comprising at least one cam assembly which can be axially displaced on a camshaft. Said assembly consists of at least two cams having different profiles and actuating optionally at least one gas exchange valve for adjusting different valve lifts and/or valve timing. The aim of the invention is to create a space-saving and simple valve drive for an internal combustion engine of the aforementioned type, which allows valve lift and/or valve timing to be adjusted without an additional actuation stage. For this purpose, one cam is connected to the camshaft so as to rotate with the camshaft and the other cam is mounted so as to be rotated on the camshaft. The cam that is rotationally mounted on the camshaft can be positively connected to and released from the cam that is connected so as to rotate with the camshaft via a controlled pilot and main locking plunger. The rotationally fixed cam has a larger profile height than the rotationally mounted cam. The larger profile height is designed for a relatively large lift of the gas exchange valve, while the lower cam profile height is designed for smaller lift heights. By displacing the cam assembly when the cams are coupled, the cam with the larger or the smaller profile height can be engaged with the gas exchange valve. A zero lift of the gas exchange valve can be adjusted, when the cam with the smaller profile height engages, by decoupling the rotational cam from the cam that is arranged on the camshaft so as to rotate therewith.

    • Die Erfindung betrifft einen Ventiltrieb für Brennkraftmaschinen zur Betätigung von Gaswechselventilen, die einstellbar mit unterschiedlichen Ventilöffnungshüben betreibbar sind. Der Erfindung liegt die Aufgabe zugrunde, einen Ventiltrieb zur Betätigung von Gaswechselventilen von Brennkraftmaschinen zu schaffen, der sich durch einen vereinfachten Aufbau bei gleichzeitiger Reduzierung der auftretenden Reibungskräfte auszeichnet. Der erfindungsgemäße Ventiltrieb zur Betätigung der Gaswechselventile besteht aus einer rohrförmig ausgebildeten Nockenwelle, die von einer Kurbelwelle der Brennkraftmaschine angetrieben wird. Auf dem Nockenwellenrohr sind ein oder mehrere drehfeste aber axial verschiebbare Nockenträger angeordnet, die jeweils einen gleichen Grundkreisabschnitt mit mehreren unterschiedlichen Nockenprofilen aufweisen. Durch Verschiebung der Nockenträger sind die Nockenprofile mit den Gaswechselventilen in Wirkverbindung bringbar. Die Verschiebung des Nockenträgers zur Ventilumschaltung auf dem Nockenwellenrohr erfolgt erfindungsgemäß durch eine im Inneren des Nockenwellenrohrs angeordnete und mit dem Nockenwellenrohr mitdrehende Schaltwelle, die über einen in einer Schaltkontur auf der Schaltwelle gleitenden Mitnehmer mit einem auf dem Nockenwellenrohr axial verschiebbaren Nockenträger in Wirkverbindung steht. Die Schaltwelle ist über ein Getriebe mit einem auf der Nockenhülse drehfest aber axial verschiebbaren Verschiebestück verbunden, das zur Betätigung der ...
