  • Patent number: 10276851
    Abstract: 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.

  • Patent number: 9067276
    Abstract: 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.

  • Patent number: 8595914
    Abstract: 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.

  • Publication number: 20100025951
    Abstract: The invention relates to an axle journal (1) which is connected to a vehicle body and which comprises an approximately rotation-symmetrical bearing journal (3) which can be connected to a wheel (5) of the vehicle. The invention also relates to a method for producing an axle journal (1). According to the invention, the axle journal is embodied in a divided manner, comprising an axle journal base body (7) and bearing journals (3), which penetrate a corresponding opening (9) in the axle journal base body (7), in order to meet the requirements of the high component stresses and to produce the axle journal (1) in an economical manner. The bearing journals (3) comprise a journal part (11) and a counter part (13), which are connected together inside the opening (9) by means of a press welding method.

  • Publication number: 20070284407
    Abstract: A joint-site structure for a shaft/disk composite workpiece, in particular for joining a shaft 1 to a connection flange 2 of a hub part of the disk by means of friction welding. A respective defined gap 4, 4? is incorporated between shaft 1 and connection flange 2 of the hub part in front of and behind a joint site 3, this gap 4, 4? preventing the spread of the material softened during the friction welding. The joint-site structure is used, for example, during the joining of a crankshaft and a hub part of a drive wheel.

  • Patent number: 6660407
    Abstract: A composite shaft/disc workpiece which is assembled from a disc with a passage hole and from a shaft by friction welding is disclosed. The outer wall of the shaft has a plurality of steps in the connection region with the disc, the radius of the steps becoming larger in a direction of the axis. The passage hole of the disc is provided with webs, the radius of which likewise becomes larger in a direction of the axis and between which annular recesses are present. The webs and steps to be connected overlap in the radial direction, so that, during the welding of the shaft and disc, annular connecting portions are obtained in the region of the webs and steps, annular cavities being formed between the connecting portions. The cavities represent a weight saving, as compared with composite shaft/disc workpices made of solid material, and can also be used as parts of media ducts.

  • Publication number: 20030006542
    Abstract: A torsion bar spring of spring steel with a high carbon content is connected fixedly in terms of rotation at its ends to structural parts. The structural parts are mounted pivotably in relation to one another. The torsion bar spring is connected in a materially integral manner to at least one of the structural parts by friction welding, condenser discharge welding, diffusion welding or medium-frequency pressure welding via intermediate pieces. As a result, a play-free and wear-free connection between the torsion bar spring and the structural part can be made in a confined construction space, and the connection is suitable for absorbing high loads, particularly alternating loads.

  • Patent number: 6378396
    Abstract: A welded crankshaft having a number of individual elements and cavities formed in the region of the main bearing journals and crank journals. The individual elements are configured so that oil passages in the overlap region between the main bearing journals and crank journals run substantially in the axial direction, and transition via radial orifices directly into the journal surface. The cavities of the main bearing journals and crank journals can be made very large, so that the weight of the crankshaft is kept light. In addition, because of the simple geometry of the oil passages, the crankshaft can be manufactured in modular fashion from the individual elements.

  • Patent number: 6050900
    Abstract: A spot weld joint of a balancing plate on the exterior side of a rotationally symmetrical, rotating hollow body such as a motor vehicle drive shaft. In order to also be able to balance thin-walled hollow bodies in a secure manner with respect to the process, as well as rapidly and durably in the case of different pairings of material of the hollow body and the balancing plate, the weld joint is constructed as an ultrasonic weld. The zone of thermal influence of the weld joint extends from the contact surface between the balancing plate and the hollow body maximally by approximately 0.3 mm, preferably approximately 0.1 to 0.15 mm, into the wall of the hollow body. Expediently, the zone of thermal influence extends deeper into the balancing plate than into the wall of the hollow body. Irrespective of the hollow shaft material--steel, aluminum or plastic--, the balancing plate may consist of a metal of high density, particularly of steel, brass or copper.
