Abstract: A device may be used to assemble a rotor segment of an electric machine. The rotor segment may include a rotor shaft, a laminated core joined to the rotor shaft, and two pressure elements that clamp the laminated core. A method for assembling the rotor segment may involve positioning the rotor shaft in the device and orienting the rotor shaft using an orienting means of the assembly device, positioning the laminated core and at least one of the first or second pressure elements within a clamping means of the device, orienting the laminated core by means of a positioning module of the clamping means, and moving the rotor shaft relative to the clamping means such that the laminated core is pushed onto the rotor shaft and the at least one of the first or second pressure elements is connected to the rotor shaft.

Abstract: A camshaft may include a shaft on which at least one sliding element is received in such a way as to be axially displaceable along a shaft axis. The shaft may comprise an external longitudinal spline structure that meshes with an internal spline structure of a passage in the sliding element such that the sliding element is arranged in a rotationally fixed manner on the shaft. The sliding element, on its axial end faces, may comprise guiding portions by way of which the sliding element is guided on the shaft to minimize an axial offset of the sliding element. Further, guiding sleeves against which the guiding portions of the sliding element are supported may be received on the shaft.

Abstract: An adjustable camshaft for a valve drive of an internal combustion engine may include an inner shaft extending through an outer shaft with a cam element disposed on the outer shaft. The cam element may be connected rotationally conjointly to the inner shaft. The cam element may have a shaft passage with an internal bearing surface, which, together with a bearing surface on an outer side of the outer shaft, forms a plain bearing arrangement for the rotatable arrangement of the cam element on the outer shaft. The bearing surface on the outer side of the outer shaft and/or the internal bearing surface of the shaft passage of the cam element may include one or more sections with a spherical shape.

Abstract: A valve train for actuating gas exchange valves of an internal combustion engine may include a first camshaft that is received such that it can be rotated in a first shaft axis, and a second camshaft that is received such that it can be rotated in a second shaft axis. At least one of the camshafts may be configured as an adjustable camshaft that comprises an outer shaft in which an inner shaft is received such that it can be rotated. At least one of the camshafts may be drive-connected via a drive means to a crankshaft of the internal combustion engine. A phase shifting member may be provided by way of which the phase position of at least one inner shaft can be changed relative to the phase position of at least one outer shaft of the camshaft. The phase shifting member may comprise an arrangement that is spaced apart from both shaft axes.”

Abstract: A camshaft module may include a module body in which at least one camshaft for controlling valves for a charge cycle of an internal combustion engine is accommodated. The camshaft may comprise a support shaft and sliding cam pieces that are accommodated on the support shaft so as to be displaceable in an axial direction of the support shaft. A support element may also be provided on which actuators for the axial displacement of the sliding cam pieces are accommodated. The support element may extend in the axial direction and therefore parallel to the support shaft. In some cases, a coefficient of thermal expansion of the support element substantially corresponds to a coefficient of thermal expansion of the support shaft.

Abstract: An oil-separating device for crankcase ventilation of an internal combustion engine may include a hollow member that extends axially in a longitudinal axis and through which a gas flow charged with oil can flow. The gas flow may flow against an oil separation ring disposed within or formed in the hollow member. The hollow member may contain a substantially rotationally symmetrical flow guiding member that has a flow projection located in the longitudinal axis and that has a flow contour that radially increases in a downstream direction so that gas can flow around the flow guiding member and so that the gas flow between the flow contour and the inner side of the hollow member can strike the oil separation ring in an accelerated manner.

Abstract: The invention relates to a camshaft comprising a support shaft formed as a hollow shaft. An inner shaft is arranged concentrically in the interior of the support shaft, wherein the inner shaft is rotatable relative to the support shaft. There is arranged on the support shaft a first cam segment with a first recess for receiving the support shaft, which cam segment is rotatable with respect to the support shaft and is connected in a rotationally conjoint manner to the inner shaft via a first opening in the support shaft. The first cam segment has at least two cam contours. The connection between the inner shaft and the first cam segment is furthermore configured such that the first cam segment is axially displaceable relative to the inner shaft and to the support shaft.

Abstract: An adjustable camshaft can be used in a valve drive of an internal combustion engine. The adjustable camshaft may include an inner shaft rotatably supported by and concentric with an outer shaft. A cam element may be rotatably supported on the outer shaft such that the outer shaft extends through a cam bore of the cam element. The cam element may be rotatably-fixed to the inner shaft, in some cases, by way of a bolt. Further, a bearing sleeve that is rotatably-fixed to the cam element may be inserted within the cam bore such that a slide bearing gap is formed between the bearing sleeve and the outer shaft. Furthermore, in some examples the cam element may be a collared cam that has a cam base body and a cam collar adjacent to one another.
