Patent number: 7794153Abstract: An axle differential mechanism includes a carrier, a bearing supporting the carrier in rotation about an axis, a bearing adjuster including a adjuster sleeve held against rotation and axial displacement, and an adjuster nut formed with first teeth, and engaged by screw threads with the adjuster sleeve such that rotation of the adjuster nut about the axis causes the adjuster nut to contact the bearing and produce a preload force on the bearing between the adjuster nut and the carrier, and a locking device secured against displacement for engaging the adjuster nut, said engagement preventing rotation of the adjuster nut relative to the bearing and maintaining the preload on the bearing.Type: GrantFiled: December 7, 2007Date of Patent: September 14, 2010Assignee: Ford Global Technologies, LLCInventors: Gerald S. Szczepanski, Charles Krysztof, Jeffrey L. Hoff

Patent number: 7008345Abstract: A planetary differential including a differential case rotatable about an axis and a method of manufacturing thereof. The differential case includes a cover, a housing, an annulus gear, and a ring gear. The differential case defines a differential cavity having a clutch cavity and a planet cavity separated by a retainer plate coupled to the housing. The modular nature of this system allows both open and torque biasing constructions in the same packaging space. The method of manufacturing the differential includes the steps of coupling a retainer plate to the housing between the clutch cavity and the axial opening, placing a planetary gear set in the planetary cavity, and fixing the housing to the annulus gear and ring gear.Type: GrantFiled: October 27, 2003Date of Patent: March 7, 2006Assignee: Automotive Components Holdings Inc.Inventors: Marj Phelan, legal representative, Gerald S. Szczepanski, Richard M. Krzesicki, Norman Szalony, James M. Story, Bhulabai S. Narayanan, Perry E. Phelan, deceased

Patent number: 6616432Abstract: A fluid pump cowling for attachment to at least a pair of helical drivetrain gears having teeth and lands. The cowling has a pair of sidewalls adapted to extend at least partially over the lands of a first of the pair of drivetrain gears and a curved sump wall extending between the sidewalls that corresponds generally to the outermost circumference of the first gear. A sump channel is defined between the sidewalls on the sump wall adjacent a distal end of the sump wall. The sump channel has a generally frustoconical shape and leads to a fluid outlet opening defined in one of the sidewalls. The cowling is positioned such that the teeth of the pair of helical gears mesh in an area in fluid communication with the sump channel to create an area of high fluid pressure upon rotational movement of the gears with a fluid.Type: GrantFiled: December 28, 2001Date of Patent: September 9, 2003Assignee: Visteon Global Technologies, Inc.Inventors: Gerald S. Szczepanski, Jonathan M. Adler

Patent number: 5845531Abstract: The present invention is directed to a reverse brake incorporated into the geartrain of a manual transmission which functions to stop inertial rotation of the input shaft prior to engagement of reverse gear. In particular, a constant-mesh gearset is operable with a first clutch to establish a forward drive connection between the input shaft and the output shaft, and is further operable with a second clutch to brake rotation of the input shaft without establishing a forward drive connection with the output shaft.Type: GrantFiled: March 18, 1997Date of Patent: December 8, 1998Assignee: New Venture Gear, Inc.Inventors: Glenn W. Fraley, Gerald S. Szczepanski
