摘要:
A launch device for a vehicle transmission including a housing, an impeller, a turbine, and first and second clutches with first and second pistons, respectively. The first and second pistons are sealingly engaged with one another. The first clutch releaseably engages the impeller with the housing and the second clutch releaseably engages the turbine with the housing. In an example embodiment, the first clutch is disposed radially outside of the second clutch. In an example embodiment, the first clutch is engaged by a first pressure, and the second clutch is engaged by a second pressure greater than the first pressure.
摘要:
A dual automatic mechanically actuated wet clutch device, for operation within a fluid tight housing, for a dual input shaft transmission that includes tightly specified average spacing between friction plate surfaces where the average spacing is selected from between about 0.05 mm to about 0.25 mm in an open position. The clutch has at least first and second independently actuatable clutch portions, and at least one clutch pack in the first or second clutch portion; and mechanical apparatus provided to move friction plates in at least one of the clutch portions toward each other so that they engage. The invention also includes apparatus and methods for adjusting and maintaining the spacing between the friction plate surfaces.

The present invention broadly comprises a ring carrier with a wall arranged to engage at least a portion of an outer circumference of a clutch pack for a clutch assembly for a vehicle and a clutch housing with a wall arranged to engage at least a portion of an inner circumference of the clutch pack. The wall for the housing includes at least one opening and the clutch housing is arranged to pump fluid through the opening in the wall independent of the rotation of an output hub for the carrier. The clutch housing can be configured as an inner clutch housing. The clutch housing includes a connecter portion arranged to transfer engine torque to the cylindrical wall from an outer housing of the clutch assembly connected to an engine crankshaft. The present invention also includes a clutch assembly with the ring carrier and clutch housing.

摘要:
A device for producing an operative connection between an internal combustion engine of a motor vehicle and a downstream transmission is described. The device is a substitute for a torque converter and can be designed as a wet clutch or a torsion damper. The installation space between the internal combustion engine and the transmission does not have to be redesigned. The only requirement for the installation of the device is to replace the transmission/engine control software.

The present invention broadly comprises a clutch housing with a housing wall disposed radially about a longitudinal axis for the housing and at least one opening in the housing wall operatively arranged to accept at least a portion of a clutch plate for a clutch assembly. The housing is substantially cylindrical and in some aspects the openings are slots substantially parallel to the axis. In some aspects, the housing wall further comprises an end and the at least one slot has an open end proximate the end or the housing wall further comprises a radial off-set proximate the end. In some aspects, the clutch housing is an inner housing or an outer housing for the clutch assembly.

A torque converter including a damper assembly connected to a hub for the torque converter; a turbine clutch connected to a turbine and the damper assembly; and a torque converter clutch connected to a cover for the torque converter and the damper assembly. In an idle mode, the turbine clutch and the torque converter clutch are disengaged and the torque converter cover is rotationally disconnected from the hub. In a torque converter mode, the turbine clutch is engaged, the torque converter clutch is disengaged, and the turbine clutch rotationally locks the turbine and the damper assembly. In a lock-up mode, the torque converter clutch is engaged and the torque converter clutch rotationally connects the torque converter cover and the damper assembly.
