20080229570 | Method for Permanently Fixing at Least One Component to a Base Component Using a Plastically Deformed Bolt - The invention relates to a method for the unreleasable fastening of at least one component to a basic component with the aid of a bolt projecting through a bore in the component or components, first the bolt being welded electrically with one end face on the surface of the basic component and subsequently being deformed plastically. So that components consisting of any desired materials can be used, it is proposed, according to the invention, that the shank of the bolt, which has a head, be upset, until the underside of the head lies in regions on the surface of the component. Furthermore, an unreleasable connection of one or more components to a basic component is proposed. | 09-25-2008 |
20090139821 | Hydrodynamic torque converter and method for producing the same - In a hydrodynamic torque converter having a turbine shell and a torsion damper spring carrier jointly mounted to a carrier part by way of rivets extending through aligned openings in the turbine shell and the spring carrier, rivets with rivet shanks and a rivet heads are inserted through the aligned openings and welded to the carrier part by pairs of electrodes by which the rivets are pressed into contact with the carrier part while a welding current is generated from one to the other of the pair of welding electrodes through the respective rivets and the carrier part. | 06-04-2009 |

20110064581 | Connection of a Shaft to a Rotating Component - For connecting a shaft to a rotating component, especially of a shaft to a turbine wheel of an exhaust gas turbocharger, an intermediate component is provided by means of which the shaft is connected indirectly to the rotating component. The connection between the rotating component and the intermediate component is a form-locking and/or force-locking connection, especially a riveted connection. The invention further relates to a method for producing said connection. | 03-17-2011 |
20110097142 | Weld Rivet Joint - A weld rivet joint between one or more components and a base component is provided. The one or more components have a hole through which a weld rivet having a head projects with its shank. The shank is welded to the surface of the base component by its end face and is plastically deformed. The weld rivet has a shank that is shorter than its head diameter, and in a transition region between head and shank a continuous annular recess is provided for the accommodation of material displaced in the riveting process and/or for tolerance compensation. | 04-28-2011 |
20120328360 | Hot Rivet Connection and Method for the Production Thereof - A method for non-releasable fixing of at least one component to a further component is provided in which a hot rivet is introduced into an opening of the at least one first component and an end face of a shank of the hot rivet is welded to a surface of the further component. Subsequently, with plastic deformation of the hot rivet, the shank of the hot rivet is compressed until a head of the hot rivet lies with a pre-stressing force at least in areas on a surface of the at least one component. The pre-stressing force, with which the head of the hot rivet lies at least in areas on the surface of the at least one component, is adjusted to a predefined value. | 12-27-2012 |
20140151945 | Arrangement for holding a first fastening element and a second fastening element on an axle element for a motor vehicle axle - In an arrangement for holding a first fastening element and a second fastening element on an axle element for an axle of a motor vehicle, in particular of a utility vehicle, the first fastening element arranged on a first side of the axle element and intended to support a spring mechanism of the axle is held on the axle element. The second fastening element is arranged on a second side of the axle element facing away from the first side and is used to support a bracket engaging, at least partially, around the axle element and intended for fastening the spring mechanism on the axle element is held on the axle element. At least one of the fastening elements is joined to the axle element by a welding rivet. | 06-05-2014 |
20140356101 | Weld Rivet Joint - A weld rivet joint between one or more components and a base component is provided. The one or more components have a hole through which a weld rivet having a head projects with its shank. The shank is welded to the surface of the base component by its end face and is plastically deformed. The weld rivet has a shank that is shorter than its head diameter, and in a transition region between head and shank a continuous annular recess is provided for the accommodation of material displaced in the riveting process and/or for tolerance compensation. | 12-04-2014 |
20140363704 | Battery Comprising a Number of Individual Cells Connected Electrically to One Another and Method for Maintaining, Repairing and/or Optimizing such a Battery - A battery includes a number of single cells interconnected in series and/or in parallel, the electrical poles of which for the electrical interconnection are connected to one another in a positive-fit and/or integrally bonded manner, directly or by means of cell connectors. The battery also includes a battery monitoring unit connected to the electrical poles and/or to the cell connectors in a positive-fit and/or integrally bonded manner. The electrical poles of the single cells, the cell connectors, and/or the battery monitoring unit have redundant contact areas for the positive-fit and/or integrally bonded connection. In each case only one of the contact areas which are redundant with one another is connected in a positive-fit and/or integrally bonded manner, and the further contact area(s) is/are not connected. | 12-11-2014 |
