WIDE-RANGE REVERSIBLE TRANSMISSION Russian patent published in 2020 - IPC F16H15/50 

FIELD: machine building.

SUBSTANCE: invention relates to the field of machine building. Wide-range reversible transmission includes housing, input and output shafts, planetary differential consisting of carrier, sun gear, gear satellites and epicycle, and a base disc friction variator consisting of an external friction epicycle and an internal friction pinion, between which there is a satellite with a device for moving its axis. Internal friction is made in form of double cone, external friction epicyclic is made with possibility of rotation, and satellite is made in form of two flat discs with axial limiters and is installed with possibility of discs movement on surfaces of friction clutches with antiphase inclination of their planes, wherein transmission is additionally equipped with reverser installed between base disc friction variator and planetary differential, wherein reverser includes two gear wheels and gears installed on axes fixed in housing, wherein the first gear wheel is fixed on the friction epicyclic, and the second gear on the carrier of the planetary differential, the sun gear of which is connected to the input shaft, and the epicyclic with the output shaft.

EFFECT: simplified design and increased reliability of the device.
