GF27.51-P-5105ACK Multidisk brake component description
- Transmission 722.695

Component Identification:

Location
With the planetary gear sets, 3 multidisk brakes are located as multidisk brake B1, multidisk brake B3 and multidisk brake B2 in the transmission housing.

Task
For transmitting the drive torque the multidisk brake supports the ring gear, sun gear or planet carrier of a planetary gear set against the transmission housing.

Design
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 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 is held on the housing via the internal plate carrier. The front planetary gears roll on the front sun gear.

If the multidisk brake B2 is engaged via the piston B2, then this presses the clutch pack together.

The center sun gear is held on the housing via the internal plate carrier.

The center planetary gears roll on the center sun gear.

If the multidisk brake is engaged B3 via the piston B3 then the rear planet carrier and center ring gear. When the multidisk brake is engaged B3 the direction of rotation reverses.
