PLANET GEAR BOX Russian patent published in 1997 - IPC

FIELD: transport mechanical engineering. SUBSTANCE: planet gear box has housing, inlet and outlet shafts, five planet rows, five controllable brakes, and two clutches. The carriers of two first rows are interconnected. The output shaft is coupled with the solar gear of the second row and, through one of the clutches, with epicycle of the first row which is connected to one of the brakes. The solar gear of the third row is coupled with the solar gear of the five row and with the carrier of the four row which is connected with the solar gear of the first row. The carrier with satellites of the third row is connected with the epicycles of the fourth and fifth rows and connected with the third controllable brake. The solar gear of the fourth row is connected with the fourth controllable brake. The carrier with satellites of the fifth row is connected with the fifth controllable brake. The output shaft is connected with epicycles of the second and third rows and with solar gear of the first row through the second clutch. EFFECT: expanded functional capabilities. 1 dwg, 2 tbl
