Patent number: 9062723Abstract: A parallel double-clutch device is arranged in a drivetrain of a motor vehicle between a drive unit and transmission of the drivetrain. The device comprises a first clutch arrangement assigned to a first transmission-input shaft for selectively transmitting torque between the drive unit and first transmission-input shaft. A second clutch arrangement is assigned to a second transmission-input shaft for selectively transmitting torque between the drive unit and second transmission-input shaft. The first clutch arrangement can be actuated by at least one hydraulically drivable first actuating piston assigned a first pressure chamber delimited by a first pressure-chamber housing and the first actuating piston. The second clutch arrangement can be actuated by at least one hydraulically drivable second actuating piston assigned a second pressure chamber delimited by a second pressure-chamber housing and the second actuating piston.Type: GrantFiled: August 2, 2010Date of Patent: June 23, 2015Assignee: BORGWARNER INC.Inventors: Hans Juergen Hauck, Christian Pilz, Jens Henze, Goetz Nicklas, Rainer Gerathewohl

Patent number: 7007783Abstract: A disk carrier assembly for a multi-disk clutch includes a drive plate having a plurality of radially extending load teeth and a plurality of radially extending bearing teeth alternately disposed about the circumference of the drive plate. A disk carrier is included that has an axially cylinder segment with a plurality of axial protrusions that extend radially inward and are alternately disposed about the segment with plurality of axial grooves that extend radially outward. The axial grooves are adapted to radially retain a plurality of clutch disks while allowing operative axial movement. The plurality of axial protrusions further include a plurality of axial load protrusions alternately disposed between a plurality of axial bearing protrusions, each of the axial load protrusion have a load tooth cutout formed on its axial end and each of the axial bearing protrusion have an elongated area with an annular retaining groove.Type: GrantFiled: November 18, 2003Date of Patent: March 7, 2006Assignee: BorgWarner Inc.Inventors: Rainer Gerathewohl, Volker Becker, Ingo Steinberg, Andreas Schmidt
