Torque Path in Reverse---Range, Converter Drive, No Steer---Schematic View

TM 9--2520--215--34 0005 00--25 THEORY OF OPERATION -- CONTINUED 0005 00 TORQUE PATHS THROUGH TRANSMISSION – Continued Torque Path In Reverse Range, Converter Drive, No Steer NOTE Refer Torque Path In Reverse--Range, Converter Drive, No Steer and Action of the Hydraulic System in, Reverse Range Converter Drive No Steer. When in reverse range, converter drive, no steer, the engine transmits torque to the turbine shaft hydraulically, through the converter. The action of the steer gear system is as described in Torque Path In Low Range, Converter Drive, No Steer. The reverse--range clutch is engaged, locking the reverse--range planetary ring gear in a stationary position. In reverse--range, two planetary gear sets are compounded to obtain reverse. These are low range and reverse range. The primary driving member of this compound arrangement is the low--range sun gear. The reaction member in the low--range planetary is the carrier. The driven member is the low--range ring gear. The reverse--range sun gear is connected to the low--range ring gear and is the driving member in the reverse--range planetary. The reaction--driv- en member is the carrier, of which the pinions and output bevel drive gear are components. Reverse rotation actually occurs in the low--range planetary while speed is further reduced in the reverse-- range planetary. The torque path through the remainder of the transmission is as described in Torque Path In Low Range, Converter Drive, No Steer. Refer to this work package for the ratios of the gears involved in the reverse--range opera- tion.
