Component description
Component |
Function |
---|---|
Forward clutch
|
• Transmits the input torque from the turbine shaft to the front sun gear.
• Operates in the forward range of the first, second, or third gear position.
|
3-4 clutch
|
• Transmits the input torque from the turbine shaft to the rear planetary carrier.
• Operates in the forward range of the third or fourth gear position.
|
Reverse clutch
|
• Transmits the input torque from the turbine shaft to the rear sun gear.
• Operates when the vehicle is backing up.
|
2-4 brake band
|
• Locks rotation of the reverse drum and fixes the rear sun gear.
• Operates in the second or fourth gear position.
|
Low and reverse brake
|
• Fixes the rotation of the front internal gear.
• Operates when the vehicle is backing up or in the first gear position (M range 1GR).
|
One-way clutch
|
• Locks the counterclockwise rotation of the front internal gear in the first gear position.
|
Planetary gear
|
• The planetary gear functions as a transmission due to the engagement/ disengagement of clutches and/or brakes, converts the transmitted driving force of the turbine shaft and transmits it to the output gear.
