Patent number: 6648055Abstract: A die provided for fixing a porous ceramic insert for producing a light metal component which is reinforced by the insert. For this purpose, the insert is positioned in the die in such a way that any force which occurs for the purpose of fixing the insert is compensated for by a collinear force, which minimizes the bending moments exerted on the insert. Furthermore, shielding elements are used to protect the insert from a casting metal flowing into the die. Furthermore, the invention describes a process in which the velocity of a casting plunger which moves the casting metal into the die is regulated in such a way that the insert is not damaged by the kinetic energy of the casting metal. This is achieved by filling the die at a low velocity until the metal has flowed around the insert. Then, the casting plunger is accelerated, thus ensuring optimum filling of the die with the casting metal.Type: GrantFiled: February 13, 2002Date of Patent: November 18, 2003Assignee: DaimlerChrysler AGInventors: Tilman Haug, Steffen Rauscher, Kolja Rebstock, Michaael Scheydecker, Markus Walters

Patent number: 6439353Abstract: A vehicle brake arrangement includes a packet of alternating stator brake disks and rotor brake disks that are parallel and rotatable relative to each other. Each stator brake disk includes a support ring, support arms that are circumferentially distributed about, connected to, and protruding radially from an outer circumference of the support ring, and plate-shaped brake segments respectively removably secured in segment-shaped spaces between neighboring ones of the support arms by pivotable latch bars and spring-biased catches engaging recesses of the brake segments. Each brake segment includes a plate-shaped carrier, and a brake pad adhered onto at least one major surface of the carrier. The pads are made of sintered metal and the rotor brake disks are made of a ceramic or ceramic composite. Selective frictional contact between the sintered metal brake pads and the ceramic rotor brake disks provides effective braking friction, and the brake segments are easily exchangeable.Type: GrantFiled: January 11, 2001Date of Patent: August 27, 2002Assignee: Airbus Deutschland GmbHInventors: Gerd Roloff, Tilman Haug

Patent number: 6221504Abstract: A tribological coating made of a copper-free highly hypereutectic aluminum/silicon alloy and/or of a copper-free aluminum/silicon composite material composed such that fine silicon primary crystals and/or silicon particles, intermetallic phases, and oxides form as hard particles during the production of the layers in the atmospheric thermal spraying method and/or are anchored in the structure. The surface of the coating can be machined economically by short-chipping using conventional tools, so that additional alloy elements such as copper for forming additional intermetallic phases such as Al2Cu can be eliminated. This is significant because conventional AlSi cylinder liners in reciprocating engines pose problems in conjunction with certain fuels because of their copper content.Type: GrantFiled: August 3, 1998Date of Patent: April 24, 2001Assignee: DaimlerChrysler AGInventors: Harald Pfeffinger, Micheal Voit, Tilman Haug, Patrick Izquierdo, Herbert Gasthuber, Oliver Storz, Axel Heuberger, Franz Rueckert, Peter Stocker, Helmut Proefrock
