Torque Path In Intermediate Range, Lockup Drive, No Steer

TM 9--2520--215--34 0005 00--22 THEORY OF OPERATION -- CONTINUED 0005 00 TORQUE PATHS THROUGH TRANSMISSION – Continued Torque Path In Intermediate Range, Lockup Drive, No Steer NOTE Refer to Torque Path In Intermediate--Range, Lockup Drive, No Steer and the Action Of The Hydraulic System In Intermediate Range, Lockup Drive, No Steer. When in Intermediate range, Lockup drive, no steer, the engine transmits torque to the turbine shaft through the lockup clutch. The action of the steer gear system is as described in Torque Path in Low Range, Converter Drive, No Steer. The Intermediate--range clutch holds the intermediate planetary ring stationary. The intermediate planetary sun gear, being splined to the turbine shaft, rotates and forces the intermediate pinions to rotate within the ring. The intermediate range planetary carrier, to which the pinions are attached, rotates. The low--range planetary ring gear is connected to the intermediate--range carrier and also rotates. The combination of rotating speed of the low--range sun gear transmits torque. The torque is then transmitted through the low--range pinion to the low--range planetary carrier. The combination of two planetaries to secure a final speed ratio is called compounding. The steer clutches are released. The outer members’ clutches are freely driven by the converter turbine shaft bevel gearing, steer cross shaft, and spur gearing. Refer to this work package for ratios of the gears involved in intermediate--range operation.
