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. 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 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 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.
Transmission
The transmission includes a first shaft, a second shaft, a third shaft, and a fourth shaft. These shafts are parallel to each other. A first gear couples to the first shaft. A second gear couples to or idles around the first shaft when a first clutch is switched. A third gear meshes with the first gear and couples to the second shaft. A fourth gear couples to or idles around the second shaft when a second clutch is switched. A sixth gear meshes with the first gear and couples to the third shaft. A seventh gear couples to or idles around the third shaft when a fourth clutch is switched. A ninth gear meshes with the second gear, the fourth gear, and the seventh gear, and couples to the fourth shaft.
Torque smoothing apparatuses for large square balers
A torque smoothing apparatus is utilized in conjunction with a large square baler (LSB), which includes a bale chamber, a plunger mounted for reciprocation within the bale chamber, and an LSB drive line. In embodiments, the torque smoothing apparatus includes a planetary gear train and a flywheel, which is mechanically coupled to the LSB drive line through the planetary gear train. An auxiliary motor having a motor output is mechanically coupled to the LSB drive line through the planetary gear train, while a controller is operably coupled to the auxiliary motor. The controller commands the auxiliary motor to selectively apply torque to the LSB drive line such that the torque applied by the auxiliary motor, taken in combination with a torque contribution of the flywheel, reduces variations in torque demands placed on a vehicle engine as the plunger reciprocates during LSB bale formation.
Method of Operating an Agricultural Vehicle and a Transmission Arrangement for an Agricultural Vehicle
A method of operating an agricultural vehicle including a range gearbox, an independent PTO system driven from an auxiliary drive shaft and a ground speed PTO system driven from an output shaft of the range gearbox. The method includes transferring torque from the auxiliary drive shaft to the output shaft of the range gear box via the independent PTO system and the ground speed PTO system while drive to the range gearbox is interrupted during a change in the range gear.
