GF27.51-P-5106ACK Freewheel, component description
- Transmission 722.695

Component Identification:

Location
In the front planetary gear set the freewheel F1 is installed between the front sun gear and stator shaft and in the rear planetary gear set the freewheel is installed between the F2 rear sun gear and the intermediate shaft.

Task
Individual shifts are optimized with the help of the freewheels. They support individual actuators of a planetary gear set in a particular direction of rotation against each other or against the transmission housing and thus permit torque transmission.

Component Identification:

The freewheels consist of an outer race, an inner race, several sprags and a sprag cage.

Function
If the inner race of the freewheel is fixed and the outer race moves in the direction of rotation "A", then the sprags assume an inclined position due to their special contour and enable a freewheel function. The outer race slides over the sprags.

If the direction of the outer race changes in direction of rotation "B", then the sprags lift up and connect the outer and inner race with each other in a locking function.
