Functions of a coupling/brake


1 — coupling of the raising transfer 2 — a brake of the raising transfer 3 — forward coupling 4 — direct coupling 5 — the second coupling of a setup 6 — the second brake 7 — a backing brake	8 — the coupling of a free wheeling No. 2 9 — the coupling of a free wheeling No. 1 10 — the coupling of a free wheeling of the raising transfer 11 — the leading shaft of the raising transfer 12 — the leading shaft of forward coupling 13 — an intermediate shaft

Name of knot	Function
Coupling of the raising transfer	Links drove the raising transfer and a solar gear wheel.
Brake of the raising transfer	Fixes a solar gear wheel of the raising transfer.
The coupling of a free wheeling of the raising transfer	Links drove the raising transfer and a solar gear wheel, only when it is brought by the engine
Forward coupling	Links the leading shaft and an intermediate shaft.
Direct coupling	Links the leading shaft to forward and back solar gear wheels.
Second brake of a setup	Fixes forward and back solar gear wheels.
Second brake	Fixes an external holder of the coupling of a free wheeling No. 1 that forward and back solar gear wheels did not move counterclockwise (the direction opposite to the direction of rotation of the engine).
Backing brake	Fixes forward planetary drove.
Coupling of a free wheeling No. 1	Does not allow forward and back solar gear wheels to turn counterclockwise, only when the second brake in work.
Coupling of a free wheeling No. 2	Does not allow a forward planetary vodil to turn counterclockwise.
