The blocking coupling of the raising planetary row (With) – connects drove also a solar wheel of the raising row.

The brake of the raising row (In) - stops a solar wheel of the raising row.

The coupling No. 1 of a free wheeling of the raising row (F1) – at the included brake of the second transfer forbids rotation counterclockwise of solar gear wheels of forward and back planetary ranks.

The coupling of the forward course (C1) – connects an entrance shaft and an epicycle of a forward planetary row.

The brake of the second transfer (B2) – stops an external ring of the coupling of a free wheeling No. 1, thus, forbidding rotation of solar gear wheels of forward and back planetary ranks counterclockwise.

The brake of the 1st transfer and backing (B3) – stops drove a back planetary row.

The coupling of a free wheeling No. 2 (F2) – forbids rotation drove a back planetary row counterclockwise.

The coupling of direct transfer (C2) – connects an entrance shaft and solar gear wheels of forward and back planetary ranks.

The brake of providing the mode of braking with the engine on the second transfer (B1) – stops rotation of solar gear wheels of forward and back planetary ranks.

The coupling of a free wheeling of the raising transfer (Fo) – at start of the engine connects a solar gear wheel of the raising planetary row and drove the raising planetary row.

Fig. 3.74. Planetary mechanism: 1 – the blocking coupling of the raising planetary row (With); 2 – a brake of the raising planetary row (In); 3 – brake of the first transfer and transfer of a backing (B3); 4 – coupling of a free wheeling No. 2 (F2); 5 – a brake of the second before
