Patent number: 10744865Abstract: A hybrid transaxle permits location of a traction motor in a more favorable location, decreasing the risk of occupant injury in a vehicle collision. Axis transfer gearing moves the generator off the engine axis, which permits placing the traction motor further forward without interference with the generator. The gearing is confined to two gear planes, reducing the transaxle width.Type: GrantFiled: October 9, 2018Date of Patent: August 18, 2020Assignee: Ford Global Technologies, LLCInventors: David Allen Janson, Jeffrey Edward Maurer, David Gon Oh, Bruce Granstrom

Patent number: 10245951Abstract: In a pump system for a hybrid electric transmission, the pump is alternately driven by the input shaft and the output shaft, whichever is rotating faster. The input shaft and output shaft are co-axial. Sprockets and a chain transmit power from axis of the input and output shafts to the axis of the pump. The driven sprocket is selectively coupled to the input shaft by a first one-way-clutch and selectively coupled to the output shaft by a second one-way-clutch. Two alternative one-way-clutch and bearing arrangement are disclosed.Type: GrantFiled: July 28, 2017Date of Patent: April 2, 2019Assignee: Ford Global Technologies, LLCInventors: Gregory Daniel Goleski, David Allen Janson, Jeffrey Edward Maurer, Matthew David Hammond

Patent number: 10132404Abstract: A transmission includes a simple planetary gear set and several clutches. A first clutch selectively couples the carrier of the planetary gear set to a first shell. The housing of the first clutch is integrated with the planetary carrier. A piston return spring extends axially to occupy space between the planet gears. A second and third clutch share a common housing that is fixedly coupled to the ring gear. The second clutch selectively couples the ring gear to the sun gear. The third clutch selectively couples the ring gear to a second shell. The planetary gear set is axially located between the two clutch housings.Type: GrantFiled: June 21, 2013Date of Patent: November 20, 2018Assignee: Ford Global Technologies, LLCInventors: Gregory Daniel Goleski, Jeffrey Edward Maurer, Steven Gerald Thomas

Patent number: 10082196Abstract: A power split hybrid transaxle includes an axis transfer chain and a final drive planetary gear set. The components are arranged such that the power split planetary gear set is opposite the final drive planetary gear set with both located at the front of the transmission. This minimized the axial length of the transaxle by limiting the number of components that must be staggered axially. Furthermore, this permits use of electric machines with a large diameter and short axial length which also reduces the total axial length of the transaxle.Type: GrantFiled: September 1, 2016Date of Patent: September 25, 2018Assignee: Ford Global Technologies, LLCInventors: David Allen Janson, Gregory Daniel Goleski, David Gon Oh, Jeffrey Edward Maurer

Patent number: 9764739Abstract: A transfer case and transmission are designed to permit the transmission hydraulic control system to control a range selection coupler and a torque on demand clutch in the transfer case. Two pressure circuits are transmitted from the transmission to the transfer case: a high range circuit and a low range circuit. The low range circuit is pressurized to engage low range while the range circuit is pressurized to engage high range. The torque on demand clutch is controlled by whichever of these circuits has the higher pressure. Lubrication is provided to a front section of the transfer case via the transmission output shaft, with the fluid returning to the transmission sump through a drainback passageway. The rear portion of the transfer case has a segregated sump. A control strategy is employed to partially fill front section of the transfer case with fluid in preparation for vehicle towing.Type: GrantFiled: November 25, 2014Date of Patent: September 19, 2017Assignee: Ford Global Technologies, LLCInventors: Laurence Andrew Deutsch, Jeffrey Edward Maurer, Steven Anatole Frait, Nicholas E.

Patent number: 9695930Abstract: Two brakes of a transmission utilize the transmission front support as a clutch housing. One brake, which selectively holds a sun gear against rotation, is located on the inside of a cylindrical wall of the front support. A second brake, which selectively holds a ring gear against rotation, is located on the outside of the cylindrical wall. The clutch pack of the inner brake is splined to the inner surface of the cylindrical wall. The reaction plate of the first clutch pack includes radial fingers that extend between axial fingers of the cylindrical wall. The portion of the reaction plate that extends to the outer side of the cylindrical wall provides a reaction for a return spring of the outer brake.Type: GrantFiled: June 11, 2015Date of Patent: July 4, 2017Assignee: Ford Global Technologies, LLCInventors: Laurence Andrew Deutsch, Gregory Daniel Goleski, Jeffrey Edward Maurer

Patent number: 9683905Abstract: 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: GrantFiled: May 12, 2015Date of Patent: June 20, 2017Assignee: Ford Global Technologies, LLCInventors: John Edward Brevick, Gregory Daniel Goleski, Jeffrey Edward Maurer, Bruce Granstrom, Yuji Fujii
