  • Patent number: 9695880
    Abstract: A drive arrangement for a drive train of a vehicle is provided. The drive arrangement includes an outer hub, an inner hub and rolling elements. The outer hub includes a fixed section and a movable section which can be reversibly connected to one another. In the disconnected state, the movable section is freely rotatable about a longitudinal axis of the outer hub. The rolling elements are displaceable in a longitudinal direction of the outer hub between the fixed section and the movable section.

  • Patent number: 9683464
    Abstract: A method for producing a camshaft module and a camshaft module are provided. The camshaft module includes a camshaft and a bearing frame having bearing devices with cut-outs. The camshaft includes a shaft and cams having cut-outs. The shaft has at least two different outside diameters. At least some of the cams and/or some of the bearing devices have cut-outs of differing diameters. The bearing frame is supported during shaft insertion to be movable along a movement axis during production of the camshaft module and to be substantially rigid along an insertion direction of the shaft. The shaft is inserted into the bearing frame in the insertion direction in such a way that interference fit is obtained in each case at least between the shaft and at least some of the cams.

  • Patent number: 9377059
    Abstract: A vibration damper and a drive shaft comprising a vibration damper having a small radial extent is provided. A first shaft part is provided with a sleeve and a second shaft part is provided with an inner part which extends axially into the sleeve. The sleeve and the inner part include longitudinal rotary drivers that engage negative profiles of an damping part which is elastically deformable in the direction of shaft rotation and includes at least one decoupling ring and at least one pair of rotation limiting rings.

  • Patent number: 9175730
    Abstract: A mounting assembly is provided for, for example, joining a cardan shaft to an axle drive of a vehicle. The mounting assembly includes a nut housing having a continuous opening arranged to receive an insert nut having a continuous internal thread, a nut having a continuous internal thread, and at least one securing element which interacts with the nut housing and the nut to constrain relative axial movement between the nut housing and the nut. The insert nut and the nut housing may be rotationally fixed relative to one another, for example using complementary polygonal outer and inner surfaces, respectively. A retainer may be provided in the interior space of the nut housing to constrain axial movement of the insert nut within the nut housing.

  • Publication number: 20140345417
    Abstract: A shaft assembly with a roller bearing arrangement is provided. The shaft has a tooth system with a specifiable number of depressions and elevations. The roller bearing is a bearing with a specifiable number of roller bodies. The roller bearing may be a needle bearing with roller bodies in the form of bearing needles. The number of depressions may be equal to, or greater than, the number of roller bodies.

  • Publication number: 20140332577
    Abstract: A method and a device for fracture splitting a connecting rod and a connecting rod formed therefrom are provided, in which a force exerted on an outer rim of an eye of the connecting rod by a separating tool is generated by an electromagnetic force. The separating tool includes at least two separating members inserted into the eye, and the electromagnetic force is generated by displacing the at least two separating members away from each other inside the eye in response to application of the electromagnetic force. The electromagnetic force may be generated by passing current through coils positioned between the at least two separating members in a manner that causes the coils to repel one another, preferably with a pulse duration of less than 100 microseconds, in order to minimize plastic deformation at the fracture locations.
