POWER SHIFT TRANSMISSION WITH CLUTCH PACK OVERRUN

摘要

A transmission system (14) comprising an input shaft (112); a first clutch (114) configured to selectively couple a first gear (116) to the input shaft (112); an output shaft (126); a second gear (138) engaging with the first gear (116),- and a second clutch (136) configured to couple the second gear (138) to the output shaft (126) when the first gear (116) rotates the second gear (138) faster than the output shaft (126).
