Patent number: 9068639Abstract: An arrangement for supporting an input gear of a transmission in a motor vehicle, in particular a ring gear, characterized in that a pot-shaped support element (1) is provided, whereby a drive gear to drive the input gear engages into a recess (2) of the support element (1), and, for purposes of bearing the input gear, the support element (1) extends at least partially underneath the input gear radially on the inside.Type: GrantFiled: October 24, 2011Date of Patent: June 30, 2015Assignee: Schaeffler Techmologies AG & Co. KGInventors: Thorsten Biermann, Fritz Wiesinger, Markus Klinger

Patent number: 8950289Abstract: A controlled axial biasing unit (1) is provided which substantially includes a first ramp disk (11) and a second ramp disk (12), each of which disks is configured with a plurality of ramp contours (8). An annular cage (2) that carries a plurality of rolling elements (3) is inserted between the first ramp disk (11) and the second ramp disk (12). At least the first ramp disk (11), the second ramp disk (12) and the cage (2) are made by a shaping method without chip removal. Each of the first ramp disk (11) and the second ramp disk (12) is configured with a continuous wall (32). Likewise through this shaping method, the first ramp disk (11) and the second ramp disk (12) have on an outer periphery (UA) an integrally formed safety stop device (14) for respective end positions.Type: GrantFiled: February 19, 2010Date of Patent: February 10, 2015Assignee: Schaeffler Technologies GmbH & Co. KGInventors: Norbert Radinger, Tomas Smetana, Fritz Wiesinger

Patent number: 8850911Abstract: A preload unit module, which has at least one ramp disk and a cage, which carries a plurality of rolling bodies that are held axially against one another in a positively locking fashion. The cage is rotationally pivotable relative to the at least one ramp disk.Type: GrantFiled: October 29, 2008Date of Patent: October 7, 2014Assignee: Schaeffler Technologies AG & Co. KGInventors: Ramon Jurjanz, Fritz Wiesinger, Tomas Smetana

Patent number: 8690445Abstract: A rolling bearing arrangement, which has at least one angular contact rolling bearing arranged within a housing and at least one lash compensation element that is supported axially in one direction on the housing and is capable of being biased against a bearing ring of the angular contact rolling bearing with the bearing ring being axially movable relative to the housing, and a U-shaped ring which has two radially opposing legs directed in an axial direction. The U-shaped ring rendering the lash compensation element radially immovable by positive engagement while being guided on the bearing ring of the angular contact rolling bearing for axial displacement relative to the bearing ring, and the axial section of the bearing ring projecting axially between the legs of the ring profile.Type: GrantFiled: September 23, 2011Date of Patent: April 8, 2014Assignee: Schaeffler Technologies AG & Co. KGInventors: Florian Doerrfuss, Thorsten Biermann, Fritz Wiesinger

Patent number: 8627734Abstract: A prestressing unit which has a first ramp disk and a second ramp disk. Ramp contours are formed in one side of an annular face of the ramp disks. In the prestressing unit, the rolling bodies ascend and/or descend on the ramp contours as a result of rotational pivoting of one of the ramp disks in relation to the other ramp disk about an axis. The ramp contours are each formed as a single-part running face for the rolling bodies. The running face is inclined with respect to the axis.Type: GrantFiled: April 14, 2009Date of Patent: January 14, 2014Assignee: Schaeffler Technologies AG & Co. KGInventors: Harald Martini, Fritz Wiesinger
