GEAR BOX Russian patent published in 2006 - IPC F16H3/44 

FIELD: mechanical engineering.

SUBSTANCE: gear box comprises input and output shafts, three planet gears, two clutches, and three brakes. Input shaft (2) is provided with solar pinion (3) of the second planet mechanism. Epicycle (5) of the planet mechanism is connected to carrier (6) of the first planet mechanism and brake (18). Epicycle (8) of the first planet mechanism is connected with carrier (9) of the third planet mechanism and output shaft (11). Epicycle (12) of the third planet mechanism is connected with carrier (13) of the second planet mechanism through clutch (15) and with solar pinion (16) of the first planet mechanism through clutch (14). Solar pinion (16) of the first planet mechanism is connected to brake (17). Solar pinion (20) of the third planet mechanism is connected with brake (19).

EFFECT: reduced sizes and weight.
