Patent number: 10851880Abstract: A transmission includes an input shaft coupled to a prime mover, a countershaft, main shaft, and an output shaft, with gears between the countershaft and the main shaft. A shift actuator selectively couples the input shaft to the main shaft by rotatably coupling gears between the countershaft and the main shaft. The shift actuator is mounted on an exterior wall of a housing including the countershaft and the main shaft. An integrated actuator housing is operationally coupled to the shift actuator and a linear clutch actuator. The linear clutch actuator is a self-adjusting actuator, and the transmission includes a self-adjusting clutch.Type: GrantFiled: November 13, 2019Date of Patent: December 1, 2020Assignee: Eaton Cummins Automated Transmission Technologies, LLCInventors: Paul Peterson, Graeme Andrew Jackson, Timothy Scott Smith, Paul Wilson, Christian Chimner, Andrzej Wota, Kirk Strehlow

Patent number: 10737696Abstract: A transmission includes an input shaft coupled to a prime mover, a countershaft, main shaft, and an output shaft, with gears between the countershaft and the main shaft. A shift actuator selectively couples the input shaft to the main shaft by rotatably coupling gears between the countershaft and the main shaft. The shift actuator is mounted on an exterior wall of a housing including the countershaft and the main shaft. An integrated actuator housing includes a single external power access for the shift actuator. A controller interprets controls the shift actuator with actuating and opposing pulses, and interprets a shaft displacement angle, determines if the transmission is in an imminent zero or zero torque region, and performs a transmission operation in response to the transmission in the imminent zero or zero torque region.Type: GrantFiled: July 28, 2017Date of Patent: August 11, 2020Assignee: EATON CUMMINS AUTOMATED TRANSMISSION TECHNOLOGIES, LLCInventors: Thomas Connolly, Joseph Paul Furner, Jeff Hawarden, Ian Daniel McKenzie, Christopher DeBoer, Graeme Andrew Jackson

Patent number: 10689001Abstract: A method of controlling a dual clutch transmission power on up shift including an on-coming clutch and an off-going clutch. The method includes implementing a prep phase comprised of decreasing torque on the off-going clutch, monitoring the off-going clutch speed to determine a slip point, and adding a bump torque to the off-going clutch when the off-going clutch reaches the slip point. The method implements a torque phase transferring torque from the off-going clutch to the on-coming clutch by increasing torque on the on-coming clutch towards an engine torque, decreasing torque on the off-going clutch, and simultaneously keeping the combination of torques greater than the slip point.Type: GrantFiled: August 31, 2018Date of Patent: June 23, 2020Assignee: Eaton Cummins Automated Transmission Technologies LLCInventors: Jeffrey S. Dunfee, II, Andrew Hart, Simon Fitzgerald, Michael Gallion

Patent number: 10591035Abstract: A dual clutch transmission includes a first and second concentric input shafts, a dual clutch assembly, a mainshaft coaxial with the first input shaft, a first countershaft, a second countershaft, and planetary range gearing with high and low ratios. The dual clutch transmission has six forward gear meshes and the high and low range ratios of the range gearing to provide ten forward gear ratios for the transmission. The transmission is powershiftable between consecutive gear ratios of the ten forward gear ratios such that no torque interrupt occurs during sequential shifts.Type: GrantFiled: June 30, 2016Date of Patent: March 17, 2020Assignee: Eaton Cummins Automated Transmission Technologies, LLCInventors: Paul Peterson, Matthew Busdiecker, Joseph Reynolds, James Walker, Thomas Stoltz

Patent number: 10473542Abstract: A transmission includes an input shaft and an output shaft, the input shaft selectively accepting a torque input from a prime mover, and the output shaft selectively providing torque output to a driveline. A controller determines a shaft displacement angle representing an angle value of rotational displacement difference between at least two shafts of the transmission, and performs a transmission operation responsive to the shaft displacement angle.Type: GrantFiled: July 28, 2017Date of Patent: November 12, 2019Assignee: EATON CUMMINS AUTOMATED TRANSMISSION TECHNOLOGIES, LLCInventors: Jeff Hawarden, Yeidei Wang, Thomas Connolly, Sipei Chen, Graeme Andrew Jackson

At least a portion of the fluid is supplied through the first cooling inlet to a first friction surface. The apparatus further includes a second cooling inlet. The fluid is supplied through the second cooling inlet to a second friction surface. The first cooling fluid inlet will selectively supply a greater volumetric flow of the fluid than the volumetric flow of the second cooling inlet.Type: GrantFiled: March 30, 2007Date of Patent: November 5, 2019Assignee: Eaton Cummins Automated Transmission Technologies LLCInventor: Martin E.
