Patent number: 9435404Abstract: A family of transmission gearing arrangements produces nine forward and one reverse speed ratio by selective engagement of various combinations of three clutches or brakes. Each transmission gearing arrangement includes a front shiftable gearing arrangement configured to establish a variety of speed ratios between an intermediate shaft and an input shaft. These speed ratios include a reverse speed ratio, a zero speed ratio, two underdrive ratios, and a direct ratio. Each transmission also includes a rear shiftable gearing arrangement configured to selectively establish particular speed relationships among the input shaft, the intermediate shaft, and an output shaft. Engagement of a clutch in the rear shiftable gearing arrangement establishes an underdrive ratio between the output shaft and the intermediate shaft.Type: GrantFiled: August 8, 2012Date of Patent: September 6, 2016Assignee: Ford Global Technologies, LLCInventors: Gregory Daniel Goleski, Steven Gerald Thomas

Publication number: 20160209280Abstract: A powertrain incorporates a link shaft between the transmission output shaft and downstream components in order to facilitate use of a torque sensor. The link shaft includes an inner section splined to the output shaft and an outer section treated to produce a magnetic field that varies based on transmitted torque. The inner section and outer section are separated by a circumferential gap that directs the torque past the treated surface. Use of the link shaft eliminates the need to directly treat the transmission output shaft. Separating the spline and the treated surface radially reduces the axial length required for torque sensing and allows commonality among variants with and without torque sensors and between two wheel drive and four wheel drive variants.Type: ApplicationFiled: May 12, 2015Publication date: July 21, 2016Inventors: John Edward BREVICK, Gregory Daniel GOLESKI, Jeffrey Edward MAURER, Bruce GRANSTROM, Yuji FUJII

Patent number: 9371000Abstract: A transmission includes provisions to mount two accessory drive units and to transmit power to the accessory drive units from an engine. The accessories are driven by an accessory drive gear that is coupled to a torque converter impeller as opposed to a turbine such that power is provided to the accessories regardless of the selected gear state or vehicle speed. The accessory drive gear also transmits power to an off-axis transmission pump. In one embodiment, power is transferred to the accessories via idler gears that is supported by the transmission housing and is present even when no accessory is installed. In another embodiment, the idler gear is supported by the accessory drive unit and is only present when the accessory is installed.Type: GrantFiled: December 18, 2014Date of Patent: June 21, 2016Assignee: Ford Global Technologies, LLCInventors: Gregory Daniel Goleski, Jeffrey Edward Maurer, Laurence Andrew Deutsch

Publication number: 20150159737Abstract: A family of transmission gearing arrangements produces nine forward speed ratios and one reverse speed ratio. Each arrangement includes a two state shift element. In a first state, the shift element passively holds a shaft against rotation in one direction while permitting rotation in the opposite direction. In a second state, the shift element holds the shaft against rotation in both directions. The shift element may be implemented as a combination of a one-way-brake and a dog clutch. Each arrangement also includes a gearing arrangement that produces three speed relationships between an input and an intermediate shaft, including an underdrive relationship, a reverse speed relationship, and holding the intermediate shaft against rotation.Type: ApplicationFiled: December 9, 2013Publication date: June 11, 2015Applicant: Ford Global Technologies, LLCInventor: Gregory Daniel Goleski

Patent number: 9011289Abstract: A clutch assembly is disclosed that combines a positively engaging dog clutch and one way clutch. The two devices are design such that the one way clutch never interferes with the engagement or disengagement of the dog clutch. In one embodiment, the one way clutch transmits torque in particular rotational positions and the dog teeth are circumferentially placed such that they do not engage in any of these positions. In another embodiment, the dog clutch piston, to which the teeth are secured, is permitted to rotate enough to accommodate any interference between dog teeth during engagement. In either embodiment, the teeth faces that transmit torque in the same direction as the one way clutch may be angled such that torque in that direction tends to disengage the dog clutch.Type: GrantFiled: December 14, 2012Date of Patent: April 21, 2015Assignee: Ford Global Technologies, LLCInventors: Gregory Daniel Goleski, Bradley Ronald Heuver
