GF27.51-P-2010ACK Multidisk clutch, component description
- Transmission 722.695

Component Identification:

Location
In the transmission housing 3 multidisk clutches are located as multidisk clutch K1, multidisk clutch K2 and multidisk clutch K3 for the planetary gear sets.

Task
To transmit the drive torque the multi-disk clutches produce a positive connection between 2 elements of a planetary gear set or between one element each of 2 planetary gear sets.

Design
A multidisk clutch consists of several internally toothed plates on an internal plate carrier and externally toothed plates on an external plate carrier.

Function

Multidisk clutch K1
If oil pressure is applied to the piston at the multi-disk clutch K1, then this presses together the inner and outer externally toothed plates of the clutch pack

The front sun gear is connected to the front and the front planet carrier via the external plate carrier and internal plate carrier Thus the front planetary gear set is locked and turns as a closed unit.

Multi-disk clutch K2
If the multi-disk clutch K2 is engaged via the piston, then this presses the clutch pack together. Via the external plate carrier and center planet carrier, on which the internally toothed plates are seated, the front ring gear of the front planetary gear set are connected to the center ring gear of the center planetary gear set. The front ring gear and the center ring gear move at the same speed as the drive shaft.

Multi-disk clutch K3
If the multi-disk clutch K3 is engaged via the piston, then this presses the clutch pack together. Via the external plate carrier and internal plate carrier the center sun gear of the center planetary gear set is connected to the rear sun gear of the rear planetary gear set The center sun gear and rear sun gear move at the same speed.
