Patent number: 9182013Abstract: A power-shiftable transmission, in particular an automatic transmission for a vehicle, which comprises a plurality of frictional shifting elements and at least one interlocking shifting element (A, B, C, D, E) and a plurality of gearwheels which can be engaged in a power flow by the shifting elements (A, B, C, D, E). In order to engage a gear step, at least two associated shifting elements (A, B, C, D, E) are engaged and at least one interlocking shifting element (B), as a shifting element (B) to be engaged, is associated with a gear step to be engaged with a supporting gear.Type: GrantFiled: September 19, 2011Date of Patent: November 10, 2015Assignee: ZF Friedrichshafen AGInventors: Gerhard Gumpoltsberger, Bernhard Sich, Matthias Reisch, Manuel Goetz, Mark Mohr, Ralf Dreibholz, Peter Ziemer, Gert Bauknecht

Patent number: 8851260Abstract: The invention relates to a positively engaging shifting element which can be hydraulically or pneumatically actuated, comprising a hydraulically or pneumatically actuatable piston (I) having a piston compartment (2) containing a hydraulic medium or pressure medium, a jaw (3) having a dog-type gearing (4) and a mating jaw (5) with which the dog-type gearing (4) meshes when engaged. The engaging speed of the jaw (3) can be increased by decoupling the jaw (3) from the hydraulic or pneumatic volume flow when the jaws (3) and (5) are in a tooth butt position in relation to each other and by pretensioning the jaw (3) by means of a mechanical device (6) that is actively connected to the piston (I). The gap between the jaws, i.e. the window into which the jaw (3) can be engaged is maintained as narrow as possible in order for a tooth butt position of the jaws (3) and (5) in relation to each other being highly probable when the shift element is applied.Type: GrantFiled: March 24, 2009Date of Patent: October 7, 2014Assignee: ZF Friedrichshafen AGInventors: Matthias Reisch, Ralf Dreibholz, Gerhard Gumpoltsberger, Mark Mohr, Manuel Götz

Patent number: 8826761Abstract: A shift element comprising at least three shift positions for shifting two gear transmission ratios in which in a first end position, which corresponds to a first shift position, the first gear transmission ratio is engaged and in a second end position, which corresponds to a second shift position, the second gear transmission ratio is engaged, while in the central position, which corresponds to a third shift position, both gear transmission ratios are engaged.Type: GrantFiled: July 28, 2008Date of Patent: September 9, 2014Assignee: ZF Friedrichshafen AGInventors: Gerhard Gumpoltsberger, Manuel Goetz, Matthias Reisch

Patent number: 8794415Abstract: The invention relates to a positively engaging shifting element which can be hydraulically or pneumatically actuated, comprising a hydraulically or pneumatically actuatable piston (I) having a piston compartment (2) containing a hydraulic medium or pressure medium, a pressure medium supply (6) for the piston (I), a jaw (3) and a mating jaw (4) with which the jaw (3) meshes when engaged. The engaging speed of the jaw (3) can be increased by decoupling the jaw (3) from the hydraulic or pneumatic volume flow when the jaws (3) and (4) are in a tooth butt position in relation to each other and by pretensioning the jaw (3) by means of a hydraulic or pneumatic pressure reservoir (7) that is actively connected to the piston (I) and that is connected to the pressure medium supply (6). The gap between the jaws, i.e.Type: GrantFiled: March 24, 2009Date of Patent: August 5, 2014Assignee: ZF Friedrichshafen AGInventors: Matthias Reisch, Ralf Dreibholz, Gerhard Gumpoltsberger, Peter Ziemer, Mark Mohr, Manuel Götz

Publication number: 20140117676Abstract: The invention relates to a generator unit (1; 31) for an agricultural or municipal commercial vehicle, in particular a tractor, comprising a generator housing (2; 35) and at least one shaft (3), which is passed in a rotating manner through the generator housing (2; 35) and forms a coupling (4) for a power take-off shaft (23) of the commercial vehicle at the first end, while a port (5) for an input shaft of an add-on device is defined through at least one shaft (3) at a second end. At least one electrical generator (6; 32), which is able to be driven through at least one shaft (3), is incorporated in the generator housing (2; 35).Type: ApplicationFiled: May 4, 2012Publication date: May 1, 2014Applicant: ZF Friedrichshafen AGInventors: Manuel Goetz, Johannes Ziegler, Martin Sagmeister, Mark Mohr

Publication number: 20130334820Abstract: An energy supply device (110) for a vehicle (100) which comprises a first electrical energy supply circuit (115) that is designed to connect a source (130,140) of electrical energy to at least one first consumer (145) which is inherently part of the vehicle. At least one electrical interface (165), coupled to the first energy supply circuit (115), is provided for a second electrical energy supply circuit (120) for supplying electrical energy to at least one second consumer (160) external of the vehicle. In this case, the interface (165) for the vehicle-external second consumer (160) of the second electrical energy supply circuit (120) is separated from the first electrical energy supply circuit (115) by a potential separator device (170) and, in particular, a galvanic potential separator device.Type: ApplicationFiled: May 22, 2013Publication date: December 19, 2013Applicant: ZF Friedrichshafen AGInventors: Manuel GOETZ, Axel Michael MUELLER, Torsten HERING, Lothar LASZIG

Publication number: 20120151903Abstract: A device (1) for driving working equipment (2) which can be connected to an agricultural commercial vehicle. The commercial vehicle has a combustion engine (6) and a generator (9) which can be driven by the combustion engine (6). The commercial vehicle and/or the working equipment (2) have at least a hydraulic pump (5), for the supply of a hydraulic working circuit (3), and a mechanical connection (4), for driving the working equipment (2). At least one hydraulic pump (5) and/or the mechanical connection (4) can be driven electrically and/or mechanically, and can be driven with a controllable rotational speed by way of the power branching.Type: ApplicationFiled: December 12, 2011Publication date: June 21, 2012Applicant: ZF FRIEDRICHSHAFEN AGInventors: Manuel Götz, Olrik Weinmann, Mark Mohr, Martin Fellmann
