| 3 - LOCKING ELEMENTS |
| 4 - OUTER RACE |
| 5 - FRONT OR REAR SUN GEAR |
| 6 - LOCKING ELEMENT CAGE |

The freewheeling clutch optimizes individual gearshifts. They lock individual elements of a planetary gear set together or against the transmission housing in one direction of rotation to allow the torque to be transmitted. See Fig 1.
If the inner race (7) of the freewheeling clutch is locked and the outer race (4) turns counter-clockwise (1), the locking elements (3) adopt a diagonal position on account of their special contours, allowing the freewheel function. The inner race (4) slides under the locking elements (3) with minimal friction. If the rotation of the outer race (4) changes to clockwise (2), the locking elements (3) stand up and lock the outer and inner races (4, 7) together.
