A transmission includes an input shaft and an output shaft, the input shaft selectively accepting a torque input from a prime mover, and the output shaft selectively providing torque output to a driveline. A controller determines a shaft displacement angle representing an angle value of rotational displacement difference between at least two shafts of the transmission, and performs a transmission operation responsive to the shaft displacement angle.

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

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

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.

A control system and method for an electromagnetic clutch brake, including an electromagnetic clutch brake actuator coil surrounding a power input shaft for a multiple-ratio transmission in a vehicle powertrain. A protective circuit of the control system normally monitors data inputs from a databus that may indicate conditions that are not favorable for clutch brake actuation. The protective circuit prevents actuation of the clutch brake under such conditions. In the event the data inputs are not available from the databus, the protective circuit permits operation in a fall-back mode in which a brake ON timer is checked prior to clutch brake actuation. A primary counter is incremented with each normal clutch brake actuation and a secondary counter is incremented with each fall-back clutch brake actuation.

Control for an electromagnetic brake for a multiple-ratio power transmission that has a brake actuation counter

A control for enhanced range shifting in a computer () assisted vehicular compound transmission having a main section (A) shifted by a manually operated shift lever () and a range section (B) shifted in response to operation of a range shift selector, such as sensing shift lever () passing through a predetermined actuation point (AR) in the shift pattern. During a compound up-shift, if the vehicle reaches a speed greater than a predetermined value during a coasting condition and the shift lever is in a low range neutral position, then the range section up-shift is automatically completed without undue wear or damage to the range section synchronized clutch (). It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims. 37 CFR 1.72(b).
