Patent number: 8863617Abstract: A motor vehicle transmission having an input shaft, which can be coupled to a drive aggregate, an output shaft, which can be coupled to an output, and several shift elements. At least two shift elements, designed as clutches, are each coupled via an outer clutch plate carrier with the input shaft in such a way that an outer clutch plate carrier of a first radially outer clutch encloses an outer clutch plate carrier of a second radially inner clutch at least sectionally and radially outside. A drive gear is coupled to the input shaft through which a power take-off can be coupled to withdraw power from the input shaft or through which an auxiliary drive aggregate can supply power to the input shaft. The drive gear is linked through the outer clutch plate carrier of the radially inner clutch to the input shaft.Type: GrantFiled: July 14, 2010Date of Patent: October 21, 2014Assignee: ZF Friedrichshafen AGInventors: Mario Holder, Dietmar Illerhaus

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: 20100137096Abstract: The invention relates to a component (4) having inner teeth (4a) and outer teeth wherein the component (4) is configured at least partially as a hollow cylindrical base body (4b) on which the inner teeth and outer teeth are disposed. It is recommended that one of the two sets of teeth, particularly the inner teeth (4a), be configured as one piece with the base body (4b) and the other set of teeth, particularly the outer teeth, be configured as an added part (6), which can be joined to the base body (4b).Type: ApplicationFiled: April 24, 2008Publication date: June 3, 2010Applicant: ZF FRIEDRICHSHAFEN AGInventors: Dietmar Illerhaus, Alfred Skrabs, Gert Hanker

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

Patent number: 7214160Abstract: The invention relates to a guide washer assembly (1) of a planet carrier for a planetary transmission having two guide washers (2, 3) which are interconnected via adequate connecting elements and held parallel at a distance from each other, the connecting elements being integral component parts of at least one of the two guide washers (2, 3). For reducing the assembly, production and storage costs and, at the same time, ensuring the durability of the guide washer assembly (1), the invention provides for the connecting elements (4, 5, 6) to be formed as dents (7) in at least one of the two guide washers (2, 3).Type: GrantFiled: July 28, 2004Date of Patent: May 8, 2007Assignee: ZF Friedrichshafen AGInventor: Dietmar Illerhaus

Patent number: 6840876Abstract: A variator for ratio adjustment of a continuously variable chain drive transmission having one variator shaft (1) and one variator pulley (2) supported upon the variator shaft (1) and axially movable by pressurizing a variator pressure chamber (31). The variator shaft (1) has on one end an axial hole (10) through which the variator pressure chamber (31) and a second pressure chamber (8) can be loaded with pressure independent of each other. The pressure is supplied to the variator pressure chamber (31) via a first section (13) of the axial hole (10) and the pressure is supplied to the second pressure chamber (8) via a non-rotating pipe (7) and a second section (15) of the axial hole (10), the pipe (7) is situated within the first hole section (13).Type: GrantFiled: June 21, 2002Date of Patent: January 11, 2005Assignee: ZF Transmission Technologies, L.L.C.Inventors: Dietmar Illerhaus, Rudolf Kauffeldt, Manfred Fischer, Thomas Lindner, Dieter Blaser, Andreas Salm
