Abstract: A hot-forming line and a method for operating the hot-forming line is disclosed having a temperature-control station and a hot-forming and press-hardening tool. A linear conveyor system for conveying the metal blank or the formed steel-sheet products, respectively, through the hot-forming line is provided.

Abstract: A motor vehicle component is disclosed. The component is manufactured by hot forming die quenching a sheet metal blank made of a hardenable steel alloy, and the motor vehicle component is made of a triple-layer laminated steel and including a central layer of hardenable steel ally, and the outer layers of a stainless steel alloy.

Abstract: A tool for hot forming and press hardening a steel structure includes an upper tool and a lower tool, each having a base body made of highly heat conductive material and comprised of at least two segments. The base body of at least one of the upper and lower tools has a cooling channel. Arranged on the base body of at least one of the upper and lower tools is a wear protection shield.

Abstract: An assembly for the transmission of electrical energy to a vehicle comprises two current rails with respective contact surfaces inclined at an angle toward each other in a roof-like arrangement and a current collector having a sliding shoe with a pair of contact surfaces inclined toward each other at the same angle. The sliding shoe is mounted movably on the current collector by means of a ball and socket joint. The support point of the sliding shoe, i.e. the geometrical center of the support ball, is located at least approximately on an imaginary line which connects the centers of gravity of the two contact surfaces of the current rails.

Abstract: A section insulator for trolley wires of electric railways is disclosed. The ends of two trolley wires are fastened to two insulating sliding strips between which arcing horns are arranged. The insulating sliding strips comprise a fiber-reinforced plastic wherein the filament fibers of the fiber reinforcement are stacked parallel to each other and are arranged perpendicularly to the sliding surface. The arcing horns are approximately U-shaped with the legs of the U-shape forming a leading runner and an adjusting loop bridged by an approximately V-shaped cross-piece. The arcing horns are disposed with the arc guiding parts facing each other and lying above the two insulating sliding strips in their operating position. Depressions are provided in the sliding surface of the insulating sliding strips to reduce accumulation of deposits.
