3.3.2. Planetary transmission
Fig. 3.73. Planetary transmission: 1 – drove the raising planetary row; 2 – an epicycle of the raising planetary row; 3 – intermediate shaft; 4 – epicycle of a back planetary row; 5 – solar gear wheels forward and back planetary ranks; 6 – in
The planetary transmission contains three planetary rows, three blocking couplings, four brakes and three couplings of a free wheeling. Power from the engine via the hydrotransformer is transferred to an entrance shaft of the planetary transmission. Gear shifting is carried out by inclusion of a combination of two elements of management therefore the frequency of rotation of an output shaft changes.
