Patent number: 11906036Abstract: A transmission capable of being assembled as a coolerless transmission and a transmission having an oil cooler includes a housing and a lubrication system. The oil passage system includes an oil passage having an oil outlet opening extending out of the housing and an oil inlet opening extending into the housing. A bypass flow passage is disposed in the housing in communication with the oil outlet opening and the oil inlet opening. In a coolerless configuration a pair of plugs are inserted in the oil outlet opening and the oil inlet opening, respectively, to close off the oil outlet opening and the oil inlet opening so that oil flows from the oil outlet opening to the oil inlet opening through the bypass flow passage. In a transmission configuration having an oil cooler, an exterior oil cooler is connected to the oil outlet opening and the oil inlet opening.Type: GrantFiled: February 27, 2020Date of Patent: February 20, 2024Assignee: Eaton Cummins Automated Transmission Technologies, LLCInventors: Adam Christopher Maurer, Graeme Andrew Jackson

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.
