Abstract:
The invention relates to a connection of electrical lines using a connection cable 2 composed of aluminum stranded wires 4 and a metallic connection part 6. Contact corrosion is avoided during welding in such a way that the connection cable 2 is connected to the connection part 6 by means of ultrasonic welding with material flow in such a way that a sealant 8 forced between the connection cable 2 and the connection part 6 during the ultrasonic welding is located between the aluminum stranded wires 4.
Abstract:
In a method for producing a cellular wheel made of metal, the following steps are conducted consecutively: (a) providing a sheet metal strip (26) having a length (1) that corresponds at least to the length of a circumferential line of an intermediate sleeve and a width (b) that corresponds at least to the length of the cellular wheel; (b) placing disks (16) in predetermined locations in predetermined quantities on both sides of the sheet metal strip (26) perpendicular to the sheet metal surface and perpendicular to the longitudinal direction of the sheet metal strip (26) and connecting the disks (16) to the sheet metal strip (26) by welding or brazing; (c) bending the metal strip (26) equipped on both sides with the disks (16) and connecting the two ends of the sheet metal strip (26) by welding or brazing to form the intermediate sleeve; (d) placing a first tubular sleeve that is concentric to the intermediate sleeve as an outer sleeve, and a second tubular sleeve that is concentric to the intermediate sleeve as an inner sleeve, and connecting the free ends of the disks (16) to the outer sleeve or the inner sleeve by welding or brazing. The method allows cellular wheels to be produced which have material wall thicknesses of 0.2 mm and less for use in pressure wave superchargers.
Abstract:
A holding device (30) of a joining tool (11) for holding a fastening arrangement (16) to be joined to a workpiece (18) is, the fastening arrangement (16) having a clip (20) and a stud (22) premounted thereon and extending along a longitudinal axis (23), the holding device (30) having at least one clip-holder finger (52) for bearing against the clip (20) and at least two stud-holder fingers (46) for bearing against the stud (22), the stud-holder fingers (46) being arranged so as to be offset in the circumferential direction with respect to the clip-holder finger (52). The stud-holder fingers (46) extend in the longitudinal direction from a stud-holder basic body (44) and can be widened elastically with respect to one another in the radial direction, so that the holding device (30) for receiving and holding the fastening arrangement (16) can be pushed onto the fastening arrangement (16) in the longitudinal direction.
Abstract:
PROBLEM TO BE SOLVED The present invention is directed to provide a high-quality fuel rail for high-pressure direct-injection internal combustion engines, in which an injector holder and a fastening bracket are directly attached to a main body of the fuel rail, and has advantage that even if thermal deformation occurs at the time of temporary fitting or brazing when assembling the rail, positional accuracy of the injector holder can be assured, which results in having an excellent sealing property. MEANS TO SOLVE THE PROBLEM The present invention also relates to a fuel rail for high-pressure direct-injection internal combustion engines, in which components of the fuel rail for direct-injection internal combustion engines are made of steel or stainless steel, and the components are reciprocally joined by brazing, characterized in that the components joined by brazing are finished by cutting work and/or burnishing processing after the brazing step.
Abstract:
Attachment mechanisms are provided that may be riveted on one end (36) and welded on another flanged end (34). The flanges (34) may allow the rivets (30, 32) to be welded to a frame or other part without additional support plates. In certain embodiments, the rivets may simplify manufacturing and packaging as well as reduce the weight of the attachment mechanism. The attachment mechanisms may promote load distribution, allow for the use of thinner materials, facilitate attachment to heat treated materials, allow for attachment of parts that are difficult to access, reduce fixturing, and improve manufacturing efficiency, among other things.
Abstract:
The invention relates to a brazing method for fastening a roof (2) to one side of a motor vehicle body having a fastening zone (13), by means of a filler material (3), which, when solidified, attaches said roof (2) to said fastening zone (13). According to the invention, the method comprises the following steps: said filler material (3) is placed on said fastening zone (13) of said body side (1); the roof (2) is positioned on top of said fastening zone (13) of said body side (1) so that said filler material (3) is placed between said fastening zone (13) of said body side (1) and a portion of said roof (2), which portion is placed facing said fastening portion (13) and at a certain distance from the edge (21) of said roof; and said filler material (3) is heated by induction through said body side and/or said roof (2) so that said body side (1) and/or said roof (2) heat said filler material (3) by conduction to a temperature equal to or greater than the melting point of said filler material (3).
Abstract:
The invention relates to a method of repairing the roof (1) of a vehicle, the roof (1) being connected to the vehicle by at least one riveted joint holding together at least three superposed parts, one of these parts (2) being connected to the body, and another of these parts being the roof, the roof having one face ia in contact with a head (12) of a rivet (10), which method is characterized in that: the head (12) of the rivet (10) is removed; the roof (1) requiring replacement is taken off; a local weld is made at the edge of a cavity (8) left by the removed head (12) of the rivet (10) in order to join the first and second parts; and a new roof is placed in position and bonded adhesively in place of the removed roof (1).
Abstract:
The invention relates to a frame structure (3') for a load-carrying vehicle (1 ') and comprising at least one frame member (4; 5) extending generally in the longitudinal direction of said vehicle (1 '), said frame member (4; 5) being divided into an upper section (6a; 9a) and a lower section (6b; 9b) by means of a slit (12; 13) extending at least along a predetermined section (4a) of said frame member (4, 5). According to the invention, said slit (12; 13) is shaped so as to allow a forced displacement of said upper section (6a; 9a) to a position in which it extends generally parallel to said lower section (6b; 9b) and in a manner so that said frame member (4, 5) is narrower along a section (4a) generally corresponding to the length of the slit (12; 13), as compared with the remaining section (4b) of said frame member (4, 5). The invention also relates to a method for manufacturing such a frame structure (3').
