Abstract: An air spring assembly for a motor vehicle, including an air spring, a rolling piston, a tubular rolling air spring bellows arranged concentrically about a central longitudinal axis of the air spring, and an air spring cover. A first partial air spring bellows has a first embedded textile reinforcement and a second partial air spring bellows has a second embedded textile reinforcement The first textile reinforcement has first reinforcing threads, the preferred axis of which extends parallel or nearly parallel to the axis of the central longitudinal axis of the air spring The second textile reinforcement has second reinforcing threads, the first preferred axis of which extends obliquely to the longitudinal axis of the air spring and the second preferred axis of which extends obliquely to the longitudinal axis of the air spring, wherein the first and the second preferred axis are at an angle to each other.

Abstract: A vehicle air spring with an elastomer material air-tight tensioned air spring bellows arranged between an air spring cover and rolling piston. The air spring bellows delimiting, with the air spring cover and the air spring rolling piston, a working chamber filled with compressed air. The air spring bellows rolling away under formation of a rolling fold on the air spring rolling piston and fastening to the air spring cover under formation of a second fold, and having an elastomer element provided as an anti-roughness bearing. The elastomer element is arranged between a first and second piston part of the air spring rolling piston, the second part arranged coaxially to the first. The rolling surface for the air spring bellows is provided on the first piston part and on which the air spring bellows is fastened by a clamping element. The second piston part is mountable on a vehicle chassis.

Abstract: A folding top frame has a corner bow with a lower end connected pivotably to a main bow. A load-bearing support is articulated pivotably on a folding top bearing, and has a guide slot, at an end opposite the folding top bearing. The corner bow is guided in the guide track by way of a journal. In the closed position of the folding top frame, the journal is at a lower end stop of the guide slot so that the corner bow is supported.

Abstract: A simplified folding-top linkage is distinguished in that the two roof-frame links are articulated directly on the two roof-frame portions, in that one of the roof-frame links has an extension, which is angled in relation to said roof-frame link and extends beyond a point of articulation located on the second roof-frame portion, and in that the drive link is articulated on the extension and the coupling link.

Abstract: A structural motor-vehicle element is made by hot-shaping and press-hardening a steel workpiece into the element and thereafter heating the hot-shaped and press-hardened workpiece to between 320° C. and 400° C. The steel workpiece constitutes in weight percent, Carbon (C) 0.18% to 0.3% Silicon (Si) 0.1% to 0.7% Manganese (Mn) 1.0% to 2.5% Phosphorus (P) max. 0.025% Chromium (Cr) up to 0.8% Molybdenum (Mo) up to 0.5% Sulfur (S) max. 0.01% Titanium (Ti) 0.02% to 0.05% Boron (B) 0.002% to 0.005% Aluminum (Al) 0.01% to 0.06% the rest iron including impurities caused by the smelting process.

Abstract: A shaped part is made by forming in a flat steel plate a thickness-reducing groove and hot-shaping and hardening the flat steel plate into a three-dimensional shape. Then the plate formed with the groove is cooled, and a piece is sheared off the cooled plate along a cut line in the groove.

Abstract: A crash box for installation between a longitudinal member and a bumper cross member of a motor vehicle, includes a sheet metal body having a deformation member which extends anteriorly of an end surface of the longitudinal member and whose maximum crumpling capability defines the energy absorption of the crash box. In prolongation of the deformation member is an attachment member which is engaged in the longitudinal member and detachably secured by bolts therein. Formed in a transition zone between the deformation member and the attachment member, is a stop which is configured in the form of an outwardly directed material protuberance or outwardly directed thickened area of the sheet metal body and bearing against the end surface of the longitudinal member.

Abstract: A pressure cylinder including a cylinder housing having one end including an opening. A piston is axially displaceable within the cylinder housing. A piston rod is coupled to the piston and extends through the opening at the one end of the cylinder. A cylinder base closes off the cylinder at an end of the cylinder housing opposite the opening. The cylinder also includes a pressure chamber between the piston and the cylinder base and capable of being pressurized by a pressure medium and a switching disk for interacting with a switch to determine the position of the piston. The switching disk is displaceably positioned in the pressure chamber in frictional engagement and coaxially with the piston rod so that the switching disk passes to a starting position near the piston in response to a pressure impulse overcoming the frictional engagement when the pressure chamber is first pressurized.

Abstract: A double pressure cylinder arrangement including a first pressure cylinder and a second pressure cylinder positioned in a spaced and axis-parallel relationship to the first pressure cylinder. A carrier strut is connected to a bottom side of the first pressure cylinder and the second pressure cylinder. The carrier strut includes a intermediate section. A substantially u-shaped housing element has two leg sections. Each leg section houses one of the pressure cylinders. Connection lines for driving the first pressure cylinder and the second pressure cylinder are integrated in the intermediate section.
