Publication number: 20200195001Abstract: An integrated inverter assembly including a main cover and an opposing back cover, a coolant channel separating body interposed between an upper coolant channel and a lower coolant channel. The upper coolant channel may be thermally coupled to a first plurality of electronic components of the integrated inverter assembly. The lower coolant channel may be thermally coupled to a second plurality of electronic components of the integrated inverter assembly. The first plurality of electronic components include at least one gate driver.Type: ApplicationFiled: December 12, 2019Publication date: June 18, 2020Inventor: Justin Keith Griffiths

Patent number: 10647321Abstract: 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: July 28, 2017Date of Patent: May 12, 2020Assignee: EATON CUMMINS AUTOMATED TRANSMISSION TECHNOLOGIESInventors: Paul Peterson, Graeme Andrew Jackson, Timothy Scott Smith, Paul Wilson, Christian Chimner, Andrzej Wota, Carlos H.

Publication number: 20200109778Abstract: 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. The shift actuator is mounted on an exterior wall of a housing including the countershaft and the main shaft. A shift control circuit operates a shift actuator using a first opposing pulse command and a first actuating pulse command, and releases pressure with shift actuating and opposing volumes of the shift actuator upon determining a shift completion event.Type: ApplicationFiled: November 25, 2019Publication date: April 9, 2020Inventors: Paul PETERSON, Graeme Andrew JACKSON, Timothy Scott SMITH, Paul WILSON, Christian CHIMNER, Andrzej WOTA, Carlos H.
