PLANETARY TRANSMISSION WITH THREE DEGREES OF FREEDOM Russian patent published in 2018 - IPC F16H3/62 

FIELD: machine building.

SUBSTANCE: invention relates to a seven-stage planetary gearbox. Proposed gearbox with three degrees of freedom contains the body, input, output and intermediate shafts, two friction clutches, four brakes and four single-row planetary gears. Its input shaft is connected to the epicyclic gear of the first planetary mechanism, the carrier of which is connected via an intermediate shaft to the sun gears of the second and third planetary gears. Driver of the second planetary gear is connected to the epicyclic gear of the third planetary gear and the sun gear of the fourth planetary gear. Driver of the third planetary gear is connected to the output shaft and to the carrier of the fourth planetary gear. On the sun gear of the first planetary mechanism and on the epicyclic gears of the second, third and fourth planetary mechanisms, brakes are installed.

EFFECT: simplified design of the gearbox, and improved performance such as reliability, mobility, agility and handling.
