Patent number: 8997961Abstract: A dual clutch arrangement for a transmission that is provided with a first input shaft and a second input shaft has a clutch housing that is connectable to a drive train in a rotationally fixed fashion. The first and second friction clutches can transmit a torque between the clutch housing and the first and the second input shafts, respectively. The first and second friction clutches are nested in the radial direction with respect to each other and actuated by a first and a second actuating unit that have pistons for pressuring clutch disk packs. The compressive force exerted by the piston of the first actuating unit and the compressive force exerted by the piston of the second actuating unit are directed in axially opposite directions with respect to each other.Type: GrantFiled: August 30, 2010Date of Patent: April 7, 2015Assignee: Getrag Ford Trasmissions GmbHInventors: Marc Absenger, Friedel Lauscher, Matthias Doelling, Andreas Hegerath, Hansi Gremplini

Patent number: 8397567Abstract: A dual clutch transmission comprising a first partial transmission and a second partial transmission is provided. A first group of forward gears is allocated to the first partial transmission, a second group of forward gears is allocated to the second partial transmission, each one of the forward gears comprises a particular transmission ratio, two adjacent forward gears comprise adjacent transmission ratios with no transmission ratio of any other forward gear in between, and at least two adjacent forward gears are allocated to the second partial transmission. Further, such a control method for controlling the dual clutch transmission is provided that a torque transmitting gap is closed when gear shifting between the aforementioned two adjacent gears.Type: GrantFiled: December 16, 2009Date of Patent: March 19, 2013Assignee: Getrag Ford Transmissions GmbHInventors: Andreas Hegerath, Ulrich Eggert, Ingo Steinberg, Christian Krauss, Wolfgang Brings

Patent number: 8333126Abstract: A dual clutch transmission is described having first and second input shafts and allowing at short axial length many degrees of freedom for providing various transmission ratios of the individual driving gears. A loose wheel of a reverse driving gear is provided on a third drive shaft and engages a first gear wheel of a step wheel. A fixed wheel of a second forward driving gear is provided on one of the input shafts and is engaged by a second gear wheel of a step wheel. The step wheel is switchable by a first gear shifting clutch that is provided on the second drive shaft and is designed as a first single gear shifting clutch allowing to connect only the step wheel in a rotationally fixed manner to the second drive shaft such that the step wheel co-rotates with the second drive shaft.Type: GrantFiled: April 16, 2010Date of Patent: December 18, 2012Assignee: Getrag Ford Transmission GmbHInventors: Hans Enstroem, Andreas Hegerath

Patent number: 8322246Abstract: A gear shift mechanism of a gear shift transmission having a plurality of gears is described. A first movable gear shift fork and at least one second movable gear shift fork are provided for engaging gears of the gear shift transmission and assuming a neutral position as well as an engaged position where a gear allocated to a respective one of the first and second gear shift forks is engaged. A locking mechanism comprising a locking element is provided that prevents that both gear shift forks can assume at the same time unintentionally an engaged position. The locking mechanism is designed such that in a locking position a force for moving the first gear shift fork out of its neutral position does not generate a resulting component of force that would force the locking element against the second gear shift fork.Type: GrantFiled: October 7, 2009Date of Patent: December 4, 2012Assignee: Getrag Ford Transmissions GmbHInventors: Matthias Doelling, Andreas Hegerath, Patrick Soehnge

Patent number: 7395908Abstract: The invention relates to a hydraulic system (1) for providing pressures and volumetric flows in a dual clutch transmission, in particular for providing a first volumetric flow for cooling and lubricating a first clutch (2) and for providing a second volumetric flow for cooling and lubricating a second clutch (3). The hydraulic system is distinguished by the fact that at least one switching valve (4), which in a first position guides a lubricating flow onto the first clutch (2) and a cooling flow onto the second clutch (3) and in a second position guides the lubricating flow onto the second clutch (3) and the cooling flow onto the first clutch (2), is connected upstream of the first clutch (2) and the second clutch (3). The cooling flow is preferably variable.Type: GrantFiled: August 31, 2005Date of Patent: July 8, 2008Assignee: Getrag Ford Transmissions GmbHInventors: Andreas Hegerath, Reinhard Möhlmann, Martin Leibbrandt, Ulrich Eggert

Patent number: 7357237Abstract: The invention relates to a clutch transmission and a method of operating the same. The clutch transmission has a transmission element that is accommodated in a transmission chamber, a clutch element accommodated in a clutch chamber, and a hydraulic controller comprising an oil pump. The purpose is to provide pressures and volume flows in the clutch transmission, in which, in order to cool the clutch element, the oil pump sucks in oil and pumps it into the clutch chamber. In order to reduce churning losses in the transmission chamber to prevent air from being sucked in by the oil pump, an intake chamber is operatively connected to an oil outlet of the clutch chamber in order to receive the oil that leaves the clutch chamber.Type: GrantFiled: September 12, 2005Date of Patent: April 15, 2008Assignee: Getrag Ford Transmissions GmbHInventor: Andreas Hegerath
