Patent number: 8272490Abstract: An arrangement of a disk spring (2) at a piston (1) of a shifting element (3) in which the fingers of the disk spring (2) protrude through crests in the housing (4) and abut against a sheet metal sleeve (5) which is held in the housing (4) of the shifting element (3). The disk spring (2) is configured as a closed ring and the outer diameter (7) of the disk spring (2) abuts against the piston (1) of the shifting element (3).Type: GrantFiled: April 3, 2008Date of Patent: September 25, 2012Assignee: ZF Friedrichshafen AGInventor: Michael Obergasser

Patent number: 8061497Abstract: A disk clutch or brake, with inner and outer disk carriers that respectively carry inner and outer disks. The inner and outer disks are arranged axially in alternation next to one another. At least one of the inner and outer disk carriers have radial openings through which coolant flows toward the disks. The inner and/or outer disk carrier have a toothed component, which is fixed to and at least partially axially and radially encompasses a basic component. The inner or outer disks are fixed toothed component to prevent relative rotation while allowing axial displacement. Radial openings are formed in the basic and toothed components to enable a flow of coolant.Type: GrantFiled: June 29, 2007Date of Patent: November 22, 2011Assignee: ZF Friedrichshafen AGInventors: Dietmar Illerhaus, Michael Obergasser

Publication number: 20090312138Abstract: A transmission with a housing, a drive input shaft, a drive output shaft and at least two planetary gear sets for transmitting rotation from the drive input shaft to the drive output shaft. The planetary gear sets each include a sun gear, a ring gear and a planetary gear carrier. At least two clutches enable connecting the drive input shaft to one of the elements of the planetary gear sets, while the ring gears can be connected to the housing with the help of further clutch devices. The bearings of the transmission are arranged in the axial direction one behind another in such manner that axial forces acting on the elements of the planetary gear stages can be transmitted, via the bearings, to the housing.Type: ApplicationFiled: June 29, 2007Publication date: December 17, 2009Applicant: ZF FRIEDRICHSHAFEN AGInventors: Dietmar Illerhaus, Klaus Muller, Gert Hanker, Michael Obergasser
