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. A controller controls the shift actuator utilizing an actuating pulse and an opposing pulse.

System, method, and apparatus for operating a high efficiency, high output transmission

A transmission includes an input shaft that couples to a prime mover, twin countershafts and a main shaft having gears coupled thereon, an output shaft that selectively provides a torque output to a driveline, a first shift actuator that selectively couples the input shaft to the main shaft. The transmission includes a second shift actuator that couples the main shaft to the output shaft with a selected reduction ratio, and a controller including a vehicle state circuit that interprets at least one vehicle operating condition, and a neutral enforcement circuit that provides a first neutral command to the first shift actuator and a second neutral command to the second shift actuator, in response to the at least one vehicle operating condition indicating that vehicle motion is not intended.

System, method, and apparatus for managing transmission shutdown operations

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.

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.

High efficiency, high output transmission

A method of controlling an automated manual transmission system having a transmission and a shifter is provided. The shifter includes a Drive Mode, a Low Mode and at least one of a Manual Mode and a Hold Mold. The Drive Mode automatically selects a default gear of the transmission and automatically performs all upshifts and downshifts. The Manual Mode permits an operator to manually select an upshift and a downshift of the transmission. The Hold Mode permits an operator to maintain a current operating gear. Control determines whether the shifter is in one of the Manual Mode and the Hold Mode. Control determines whether a vehicle operating condition is outside of a predetermined threshold. Control operates the transmission in Drive Mode based on the vehicle operating condition being outside of the predetermined threshold irrespective of the shifter being in one of the Low Mode, Manual Mode or Hold Modes.
