Patent number: 11673552Abstract: 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 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: January 27, 2021Date of Patent: June 13, 2023Assignee: Eaton Cummins Automated Transmission TechnologiesInventors: Paul Peterson, Graeme Andrew Jackson, Paul Wilson, Christian Chimner, David L.
