GF27.51-P-5105AHK Multidisk brake component description
- Transmission 722.904/906/907/999

Component Identification:

Location
In planetary gear sets 4 multi-disk brakes consisting of multi-disk brake B1, multi-disk brake B3, multi-disk brake BR and multi-disk brake B2 are located in the transmission housing.

Task
To support the ring gear, sun gear or planet carrier of a planetary gear set relative to the transmission housing, to transmit the drive torque.

Component Identification:

A multidisk brake consists of several internally toothed plates on an internal plate carrier and externally toothed plates on an external plate carrier. The external plate carrier is permanently connected with the transmission housing. Single sided lamella are used for the multidisk brakes B1 and B3 On this type of lamella the friction lining is only applied on one side.

Among other things, this improves heat distribution in the disk pack, the design of the disk pack is more compact, the load-bearing capacity is increased and the mass is reduced. On multidisk brakes B2 and BR, disks coated on both sides continue to be used.
