  • Patent number: 10862360
    Abstract: A rotor segment of an electric machine may include a rotor shaft and a laminated core, which is arranged on the rotor shaft in such a way that a gap dimensioned sufficiently large in the radial direction for the passage of a cooling medium is produced between an outer surface of a hollow cylinder shell and an inner surface of the laminated core. The rotor segment may further include two pressure elements that are held on the rotor shaft in a stationary manner such that the pressure elements axially clamp the laminated core. Further, at least one of the pressure elements is designed as a holding segment allowing cooling medium to pass through.

  • Patent number: 10247051
    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.

  • Patent number: 10224774
    Abstract: A method for mounting laminated sheets onto a shaft of a rotor provided for an electrical machine may involve sliding the laminated sheets onto the shaft and bracing the laminated sheets between two rotation-resistant thrust washers connected with the shaft. The laminated sheets may be slid onto the shaft to lie against a stop in the form of a first thrust washer arranged upon a first subsection of the shaft. A second thrust washer may be pressed in by axially bracing the laminated sheets onto a second axial subsection of the shaft in a frictional interlocking manner. The second thrust washer may be positioned after a surface of the second subsection has been enlarged by the introduction of an exterior surface profile.

  • Patent number: 10208632
    Abstract: An adjustable camshaft may include an outer shaft that is hollow and an inner shaft received in the outer shaft and rotatable in the outer shaft. The inner shaft may include a cavity into which oil can be applied. At least a first radial opening may be configured in the outer shaft and at least a second radial opening may be configured in the inner shaft.

  • Patent number: 10180159
    Abstract: A bearing apparatus for mounting a camshaft in a cylinder head of an internal combustion engine may include a bearing element that surrounds a bearing ring in which the camshaft is rotatably mounted or mountable. The bearing element may be made of a first material whose expansion coefficient is greater than an expansion coefficient of a second material of which the bearing ring is made. An outer surface of the bearing ring may include a contour that engages in a form-fitting manner with a mating contour formed on an inner surface of the bearing element that surrounds the bearing ring. The contouring formed by the contour and the mating contour may form retaining structures that brace against one another in instances of thermal expansion.

  • Patent number: 10132202
    Abstract: An adjustable camshaft can be used in valve drives of internal combustion engines, amongst other places. The adjustable camshaft may include an outer shaft and an inner shaft that is concentric with and rotatably supported in the outer shaft. A cam having a cam bore may be rotatably supported on an outer surface of the outer shaft so as to form a slide bearing gap between the cam and the outer shaft. The cam may be rotatably-fixed to the inner shaft so that the inner shaft and the cam rotate with one another. Furthermore, the adjustable camshaft may include an oil channeling groove disposed beneath the cam in the outer surface of the outer shaft. In many cases, at least one side of the oil channeling groove may be exposed such that it extends beyond the slide bearing gap and the cam.

  • Publication number: 20180298789
    Abstract: A method may be used to adjust a gap between a stator and a rotor of a phase shifter for an adjustable camshaft. The stator may be connected to an outer shaft, and the rotor may be connected to an inner shaft of the adjustable camshaft. When the rotor rotates in the stator, a phase position of the inner shaft is adjusted relative to a phase position of the outer shaft. A gap may be formed between sliding surfaces on the stator and rotor. The method may involve coating at least one of the sliding surfaces with a removable coating, assembling the phase shifter including a joining of the rotor in the stator, starting up the phase shifter by rotating the rotor in the stator, and adjusting the gap between the stator and the rotor by way of abrasion of at least a partial thickness of the coating.

  • Patent number: 10066524
    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.

  • Patent number: 10054013
    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.

  • Patent number: 9957860
    Abstract: An oil separator may be used in a variety of contexts, one of which is for crankcase ventilation of an internal combustion engine. The oil separator may include a hollow member that extends along a longitudinal axis and is configured to receive a gas flow that is charged with oil. The oil separator may also include an oil separation member disposed within the hollow member and against which the gas flow flows. A redirection member may be disposed proximate the oil separation member in the hollow member, wherein the redirection member redirects at least a portion of the gas flow traveling substantially along the longitudinal axis radially outwards so as to impact an inner side of the oil separation member. As a result of an impactor effect from the gas flow striking the oil separation member as well as the inertia of the oil, the oil may remain in and/or pass through the oil separation member.
