US Patent:
6508346, Jan 21, 2003
Filed:
Oct 16, 2000
Appl. No.:
09/690032
Inventors:
William Ralph Simpson - Saline MI
Assignee:
Ford Global Technologies, Inc. - Dearborn MI
International Classification:
F16H 4502

US Patent:
2009002, Jan 22, 2009
Filed:
Jul 17, 2007
Appl. No.:
11/879434
Inventors:
James T. Gooden - Canton MI, US
Jacob M. Povirk - Franklin MI, US
William R. Simpson - Saline MI, US
Jacob M. Povirk - Franklin MI, US
William R. Simpson - Saline MI, US
International Classification:
F16D 33/10
US Classification:
192 33
Abstract:
A hydraulic system for supplying fluid to a torque converter of an automatic transmission for a vehicle driven by a power source includes a torque converter including an impeller, a turbine, and an impeller clutch for alternately engaging and disengaging a drive connection between the impeller and the power source, a hydraulic control system producing line pressure and converter charge pressure that communicates with the impeller clutch, a discharge line communicating with the impeller clutch and through which hydraulic fluid discharges from the torque converter at a discharge pressure similar to the first pressure, thereby minimizing a pressure differential across the impeller clutch tending to disengage the impeller clutch, and an oil cooler to which fluid is supplied from at least one of the source of line pressure and the converter discharge line and from which fluid returns to the control system.

US Patent:
7815026, Oct 19, 2010
Filed:
Mar 15, 2007
Appl. No.:
11/724617
Inventors:
Jacob M. Povirk - Franklin MI, US
William R. Simpson - Saline MI, US
William R. Simpson - Saline MI, US
Assignee:
Ford Global Technologies, LLC - Dearborn MI
International Classification:
F16H 45/00, F16H 45/02
US Classification:
192 326, 192 33, 192 333
Abstract:
A system for controlling a torque converter of an automatic transmission driven by a power source, the system including a torque converter an impeller, a turbine driveably connected to a transmission input and able to be driven hydrokinetically by the impeller, a stator, an impeller clutch for alternately engaging and disengaging a drive connection between the impeller and the power source, a source of converter charge pressure communicating with the impeller clutch, a source of converter discharge pressure communicating with the impeller clutch, a magnitude of differential force due to charge pressure and discharge pressure across the impeller clutch alternately producing operating multiple operating states of the impeller clutch, and a orifice having a variable fluid flow area for changing a magnitude of converter discharge pressure.

International Classification:
F16H 61/48
US Classification:
192 333, 192 326, 192 33
Abstract:
A method for controlling an impeller clutch of a torque converter includes determining a function relating a K-factor of the torque, determining a current engine torque, determining a desired impeller clutch slip, using the function determine the actual impeller speed and thus actual clutch slip, and adjusting the operating state of the impeller clutch to produce the desired impeller clutch slip.
