摘要： A gas exchange valve of an internal combustion engine, has valve lifting movements with valve displacement curves and a control unit. To this end, a control unit is provided for operation of at least one valve, in particular a gas exchange valve of an internal combustion engine, in which the valvelifting movement of the at least one valve (6) is generated by superimposing two synchronously rotating cam profiles acting mechanically on a lift operating element (4). The two cam profiles (1, 2) have specially shaped areas by means of which, when superimposed to form one of the two cam profiles (1, 2), at least one additional valve displacement (ZV) can be generated on the whole in addition to a main valve displacement movement (HV) over a full revolution of each of these cam profiles (1, 2).

摘要： A camshaft of an automotive engine includes two concentric contra-rotating shafts mounted one inside the other, namely an inside shaft and an outside shaft, at least one cam rotatably mounted on the outside shaft, fixedly connected to the inside shaft radially through the outside shaft via a fastening mechanism, a sleeve gripped by the fastening mechanism and inserted fixedly into aligned boreholes in the inside shaft and in the cam, a core that widens the material of the sleeve within its elasticity limits in the area of the inside shaft and is inserted into the sleeve after insertion of the sleeve into the shaft mechanism. To improve mountability, the core extends over the entire length of the sleeve and widens it beyond the area limited by the inside shaft without exceeding the upper limit of elasticity of the material of the sleeve in comparison with its uninstalled starting state.

摘要： A camshaft for activation of the gas exchange valves of an internal combustion engine has two coaxially mounted shafts rotatable inside and with respect to one another, first cams fixedly attached to the first shaft and second cams fixedly attached to the second shaft, a main camshaft drive acting on both shafts, and a device for adjusting the angle of rotation of the first and second shafts with respect to one another by a first actuating drive and adjusting the angle of rotation of both shafts jointly by a second actuating drive. The adjusting device has a rapid response and allows large adjustment angles with a simple structural design.

摘要： A joined prefabricated individual cam (1, 2), comprising multiple cams for an adjustable camshaft in particular for an internal combustion engine of a motor vehicle, whereby the camshaft has two shafts mounted concentrically one inside the other, namely an inner shaft and an outer shaft, and the joined multiple cam is fixedly pinned to the inner shaft via radial openings provided in the outer shaft with a rotatable bearing on the outer shaft, should be easy and inexpensive to manufacture. To this end, such a multiple cam is characterized in that at least one prefabricated individual cam (1, 2) is placed as a cam ring on the outside circumference of a carrier pipe (3″) at an axial distance from the neighboring individual cams (1, 2) and is fixedly connected to this carrier pipe (3″) at a predetermined angle of rotation and axial distance assignment.

摘要： A camshaft has contrarotating cams for automotive engines, in which an inside shaft and an outside shaft are arranged concentrically so they are contrarotating, at least one cam has at least one main cam element that can be placed radially on the outside shaft and is supported there so it can rotate. The main cam element is connected to the inside shaft in a manner that is rotationally locked via a fastener passing through a recess in the outside shaft. Further features include a fastener, a main cam element and a locking means. The fastening of the main cam element to the inside shaft is provided by widening the outside diameter of the fastener by the locking means with a resulting tightly seated connection between the fastener and the inside shaft, and the fastener and the locking means.
