GEAR VARIATOR Russian patent published in 2023 - IPC F16H47/04 

FIELD: mechanical engineering.

SUBSTANCE: gear variator includes a differential and a planetary gearbox with a common shaft, on which the axis of the differential pinions and the carrier of the planetary gearbox are located. Braking of the differential side gear is enabled by the NSh pump by reducing the discharged oil flow by a valve controlled by the gas pedal. The second semi-axial gear of the differential is configured to transmit rotation with a decrease by half through the block of gears of the intermediate shaft to the smaller sun gear, the number of teeth of which is one tooth less than the number of teeth of the second sun gear on the output shaft of the planetary gearbox.

EFFECT: creation of a high reliability variator.
