Patent number: 7740541Abstract: A drive shaft is provided with a sleeve enclosing at least sections thereof. The sleeve is fixed to the drive shaft in order that it may rotate with the drive shaft. The sleeve forms a heat shield with heat-reflecting and/or heat-insulating properties. This serves to effectively reduce the heat input into the drive shaft. In contrast to conventional heat shield plates, the problem of fixing is eliminated. Moreover, a heat shield sleeve according to the invention can also still be fitted in situations wherein the space is too restricted for a heat shield plate. In addition a savings in weight and material also results.Type: GrantFiled: November 2, 2005Date of Patent: June 22, 2010Assignee: Volkswagen AGInventors: Dietmar Hirsch, Jürgen Linzmeier

Patent number: 7690074Abstract: The invention relates to a connecting device for a blade on the wiper arm of a windshield wiper system, the wiper blade being formed by a springy support element that is provided with a wiper strip. The inventive connecting device comprises a holding mechanism that is fastened to the outer edges of the support element, and a connecting bolt which is disposed on the holding mechanism and runs transversal to the longitudinal extension of the wiper blade. The aim of the invention is to design such a connecting device in such a way that the parts which are subject to wear are placed on the wiper blade. The aim is achieved by the fact that an adapter bracket is hinged to the connecting bolt. The final piece of the wiper arm, which is adapted to the adapter bracket, can be joined in a fixed and detachable manner to the adapter bracket via a locking connection or latch and is connected thereto in a fixed manner in the assembled state of the wiper blade.Type: GrantFiled: November 9, 2005Date of Patent: April 6, 2010Assignee: Volkswagen AGInventor: Wolfgang Ostrowski

Patent number: 7682723Abstract: A membrane for fuel cells, which is characterized by a homogeneous absorption and good retention of doping agents, and which guarantees a high mechanical stability at high temperatures when doped. Such membranes consist of at least one polymer, whose nitrogen atoms are chemically bonded to a central atom of a derivative of a polybasic inorganic oxo acid. The membranes are produced from polymer solutions that are devoid of water and oxo acid derivatives, by heating the solution that has been introduced into a membrane mold until a self-supporting membrane has been formed and then by thermally regulating the latter. Inventive fuel cells having a membrane electrode assembly (MEA) that comprises a membrane of the invention and phosphoric acid as the doping agent have, for example, an impedance of 0.5-1 ?cm2 at a measuring frequency of 1000 Hz and at an operating temperature of 160° C. and a gas flow for hydrogen of 170 mL/min and for air of 570 mL/min.Type: GrantFiled: August 4, 2006Date of Patent: March 23, 2010Assignee: Volkswagen AGInventors: Dieter Melzner, Annette Reiche, Ulrich Maehr, Suzana Kiel, Stefan Haufe

Patent number: 7678018Abstract: A method for implementing shifts from a source gear to a target gear of an automatic shift transmission includes storing a respective upshift threshold and a respective downshift threshold for each possible sequential gear shift. The respective upshift threshold and the respective downshift threshold are defined in dependence of an accelerator pedal position, such that a limit value that is valid for a respective upshift or downshift is stored as a vehicle speed value in a control device. The vehicle speed that changes while the motor vehicle is driving and a changing accelerator pedal position are measured. Downshifts are simplified for a driver by configuring at least two downshift thresholds to be substantially horizontally extending in a first region of a possible accelerator pedal position and at least partly step-shaped in a second region of the possible accelerator pedal position.Type: GrantFiled: May 23, 2007Date of Patent: March 16, 2010Assignee: Volkswagen AGInventor: Stephan Schaefer
