Patent
·
OSTI ID:6092051
A multistate transmission is described having an input shaft and an output shaft comprising: a. planetary gear train means having a ring gear, planetary gears with planetary gear carrier, and a sun gear, the planetary gear train means connected to the output shaft; b. first bypass means connecting the input shaft to the planetary gear train means; c. differential transmission means for receiving its input from the input shaft and having means to adjust the torque and speed output infinitely variable over its range of operation for each state of the transmission; d. power return means for receiving the output of the differential transmission means; e. means including clutch operated speed reversing means for interconnecting the sun gear in the planetary gear train means with the power return means; f. the power return means including a first gear to receive the output of the differential transmission means; g. first multispeed transmission means connecting the means for supporting the carrier shaft to the first bypass means.
