GF27.51-P-5105G Multi-disk brake, component description
- TRANSMISSION 722.6
- up to model year 08






Location
With the planetary gear sets, 3 multi-disk clutches as multi-disk clutch B1, multi-disk clutch B3 and multi-disk clutch B2 are located in the transmission housing.

Task
To transmit the drive torque the multi-disk brake supports the ring gear, the sun gear or planet carrier of a planetary gear set against the transmission housing.

Design
A multi-disk brake consists of several internally toothed plates on an internal plate carrier and externally toothed plates on an external plate carrier which is permanently connected to the transmission housing.





Function
If oil pressure is applied to the piston B1 at the multi-disk clutch B1, then this presses together the inner and outer externally toothed plate of the clutch pack. The front sun gear on the housing is held via the internal multiple-disc carrier. The front planetary gear turns on the front sun gear.

If the multi-disk clutch B2 is connected via the piston B2, then this presses the clutch pack together. The center sun gear is held in the housing via the internal multiple-disk carrier. The center planetary gear turn on the center sun gear. If the multi-disk brake B3 is engaged via the piston B3, then the rear planet carrier and center ring gear are held. When the multidisk brake B3 is engaged the direction of rotation reverses.
