Publication number: 20120196716Abstract: A transmission device for distributing drive torque between two output shafts. The device comprises three planetary gearsets (2, 3, 11). An input shaft is connected to a first element of gearsets (2, 3). The output shafts each couple a second element of gearsets (2, 3). A third element of gearset (2) couples a first element of gearset (11) and is connectable, via brake (14), to the housing. A third element of gearset (3) is connectable, via brake (17), to the housing and, via a claw shifting element (24), to a second element of gearset (11). A third element of gearset (11) couples the housing. Claw shifting elements (24, 18) couple the brakes (14, 17) such that, to engage brakes (14, 17), the claw shifting elements are first coupled to the first element of gearset (11) or the third element of gearset (3), and then the brakes are engaged.Type: ApplicationFiled: December 22, 2011Publication date: August 2, 2012Applicant: ZF FRIEDRICHSHAFEN AGInventor: Thomas ROSEMEIER

Patent number: 8182386Abstract: A transmission device with at least two output shafts and at least two multi-shaft planetary gearsets that are actively connected with one another. A shaft of a planetary gearset can be actively connected with an output shaft. In addition, a shifting mechanism, located between the two output shafts, shifts between a first power path or a second power path. In one of the planetary gearsets, torque from an electric machine can be transmitted along either the first or the second power path. In the first power path, torque from the electric machine is transmitted to the two output shafts in equal parts and with the same sign. In the second power path, torque is transmitted to the two output shafts in equal parts but with opposite signs. The planetary gearset, in the area of which the torque from the electric machine can be transmitted, is a simple negative planetary gearset.Type: GrantFiled: December 8, 2008Date of Patent: May 22, 2012Assignee: ZF Friedrichshafen AGInventors: Thomas Rosemeier, Bernd-Robert Hohn, Christoph Pelchen
