Patent number: 8739524Abstract: A torque converter including a cover, a turbine pump in fluid contact with the turbine, and a pump shell connected to the cover. The torque converter includes a pump hub connected to the pump shell such that the pump shell and the pump hub are fixed with respect to rotation. The pump hub also includes a portion with a distal end having a plurality of indentations and a plurality of sloped surfaces in contact with the plurality of indentations. The plurality of sloped surfaces is arranged to receive a plurality of protrusions for a transmission pump gear and to urge the pump hub or the pump gear into rotational motion to urge the plurality of protrusions into mating engagement with the plurality of indentations.Type: GrantFiled: December 20, 2010Date of Patent: June 3, 2014Assignee: Schaeffler Technologies GmbH & Co. KGInventors: William Brees, Philip George, Michael Van Sickle, Edward Pasho

Publication number: 20110150670Abstract: A pump for a transmission, including: a housing with a pneumatic port; and a gear for engaging with a pump hub for a torque converter, wherein the pneumatic port is for introducing compressed air into the housing to restrict rotation of the gear. In an example embodiment, restricting rotation of the gear is to prevent rotation of the gear when the gear is interfaced with the pump hub to rotationally lock the gear with the pump hub. A pump for a transmission, including: a housing; a gear for engaging with a pump hub for a torque converter; and, an element for enabling rotation of the gear in a first rotational direction and locking the gear with respect to rotation in a second rotational direction, opposite the first rotational direction. In an example embodiment the element includes a one-way clutch.Type: ApplicationFiled: December 20, 2010Publication date: June 23, 2011Applicant: SCHAEFFLER TECHNOLOGIES GMBH & CO.

Patent number: 7850426Abstract: The present invention broadly comprises a torque converter including a cover arranged to accept torque from a drive unit and an impeller. The cover and the impeller are joined by a crimped connection. In some aspects, the converter includes a sealing element disposed between the cover and the impeller and the sealing element is selected from the group consisting of an o-ring and a gasket. In some aspects, the cover is a cast piece. In some aspects, the cover is formed by a process selected from the group consisting of: molding, compression molding, and pressed metal forming. In some aspects, the cover is a stamped metal piece. The present invention also broadly comprises a torque converter including a cover, an impeller, and an induction brazed connection joining the cover and impeller. In some aspects, the cover further comprises axially disposed fingers engaged with the impeller.Type: GrantFiled: March 23, 2007Date of Patent: December 14, 2010Assignee: Schaeffler Technologies GmbH & Co.
