Geartrain

DESCRIPTION
The geartrain consists of the planetary gearsets, apply components, final drive gearset and differential.





PLANETARY GEARSETS
The CD4E transaxle has two planetary gearsets to provide operation in reverse and four forward speeds.

TURBINE SHAFT
The turbine shaft connects the torque converter stator with the forward/coast/direct clutch cylinder. When applied, the forward/coast/direct clutch cylinder transmits input torque to the reverse/overdrive ring gear assembly which also acts as the drive sprocket. This allows input torque to be transmitted from the torque converter to the drive chain and driven sprocket.





DRIVE CHAIN AND SPROCKETS
A chain drive transfers torque from the torque converter turbine to the planetary gearsets. The drive chain connects the reverse to overdrive sun gear with the driven sprocket. The final drive sun gear located on top of the driven sprocket meshes with the final drive gearset.

FINAL DRIVE GEARSET
The final drive consists of a planetary gearset that transfers and multiplies torque from the planetary gearsets to the differential. The final drive consists of the following components:
- sun gear (part of the driven sprocket)
- carrier (part of the differential case)
- ring gear
The sun gear is located on top of the driven sprocket and acts as the driving member. The final drive carrier acts as the driven member. The ring gear uses lugged teeth to hold stationary inside the transaxle case.

DIFFERENTIAL
The differential allows the halfshafts and wheels in rotate at different speeds during cornering.
