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.

High efficiency, high output transmission having ease of integration features

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.

High efficiency, high output transmission having an aluminum housing

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.

Clutch control for a high efficiency, high output transmission having improved response and position control

A transmission selectively coupled to an engine crankshaft of an internal combustion engine arranged on a vehicle includes an input shaft, a mainshaft, an output shaft, a first countershaft and a second countershaft. A first gear set includes a first mainshaft gear arranged on the mainshaft, a first countershaft gear arranged on the first countershaft and a first countershaft gear arranged on the second countershaft. A second gear set includes a second mainshaft gear arranged on the mainshaft, a first countershaft gear arranged on the second countershaft and a second countershaft gear arranged on the second countershaft. The gears of the first gear set all have a first helix angle. The gears of the second gear set all have a second helix angle. The first and second helix angles are selected to provide gear constant leading whereby thrust forces directed onto the first and second countershafts are balanced.
