摘要： A method for producing a shaft-hub connection having a secondary bearing seat that is on the shaft and that is axially at a distance from the shaft-hub connection includes determining a dimensional deviation relative to a final dimension of the bearing seat as a derivative action for a deformation of the bearing seat. A final machining of the bearing seat is performed with the dimensional deviation before assembly of the shaft-hub connection. Then, the shaft-hub connection is produced by a press-fit connection. The deformation of the shaft caused by the shaft-hub connection deforms the bearing seat to the final dimension, in that the deformation of the shaft compensates for the dimensional deviation of the bearing seat.

摘要： A cylinder head of an internal combustion engine includes a camshaft configured to actuate gas-exchange valves of the internal combustion engine. The camshaft has two cam segments that are joined to each other in such a manner that the cam segments cannot rotate with respect to each other, but are moveable axially relative to each other. End faces of the bearing sites of the cam segments each have splines running radially along respective outer circumferential surfaces of the cam segments. A camshaft bearing has an inner bearing ring with splines being formed on an inner surface. The splines of the inner bearing ring completely penetrate the axial course of the inner surface and the splines of the adjacent cam segments intermesh with the splines of the inner bearing ring on both sides thereof such that the inner bearing ring forms a non-rotating connection between the camshaft segments.

摘要： An adjusting shaft actuating device of a valve train for internal combustion engines includes a cam unit with first and second cams rigidly connected thereto. The second cam is spaced apart from the first cam in axial and peripheral directions. The device also includes a lever unit non-rotatably arranged on an adjusting shaft with first and second lever arms rigidly connected thereto. The second lever arm is spaced apart from the first lever arm in axial and peripheral directions. The first and second cams are configured to be brought into respective operative connections with the first and second lever arms by an axial alignment between the cam unit and lever unit. The first and second cams and the first and second lever arms are arranged such that the first operative connection and the second operative connection are produced during a rotation of the adjusting shaft in a temporally consecutive manner.

摘要： A method for monitoring a power electronic assembly is improved to be more effective and versatile. It includes converting and/or modifying an electrical input into at least one electrical output by a conversion and/or modifying process which proceeds in connection with the power electronic assembly. During the conversion and/or modification a bit stream is generated by a delta-sigma modulator and represents the electrical value, that is to say the electrical input or the at least one electrical output. One bit stream each can also be generated by a plurality of delta-sigma modulators and represents the respective electrical value, that is to say the electrical input and the at least one electrical output. The power electronic assembly is monitored based on the one bit stream(s) thus generated and available as a result. The bit stream(s) is/are not demodulated, and therefore very meaningful information of the corresponding useful signal is provided.
