PLANETARY TRANSMISSION Russian patent published in 2012 - IPC F16H3/54 

FIELD: machine building.

SUBSTANCE: planetary transmission (100) includes inlet element (13), outlet element (19), braking element, planetary transmission assembly (13, 14, 15, 16, 17), centrifugal coupling (40), free travel coupling (22), which are mechanically located between inlet and outlet elements. Free travel coupling is intended for direct connection of inlet and outlet elements from zero rotation frequency to the first rotation frequency. Centrifugal coupling is intended for direct connection of inlet and outlet elements from the second rotation frequency which is higher than zero rotation frequency to the third rotation frequency exceeding the first rotation frequency. Braking element is intended for selective rotation control of planetary transmission assembly.

EFFECT: reducing power losses and improving performance characteristics of the device.
