PLANETARY COORDINATING GEAR BOX Russian patent published in 2015 - IPC F16H48/00 

FIELD: machine building.

SUBSTANCE: planetary coordinating gear box contains casing, planetary machinery with movable in axial direction pinion carrier, on which satellite gear is secured with possibility of rotation, two coaxial input shafts (internal and external) entering the planetary coordinating gear box from face side, with small central tooth-wheels fit seated on each of these shafts, output shaft leaving the planetary coordinating gear box from rear side, and drive of pinion carrier axial movement. Large central wheel of the planetary gear is permanently engaged with satellite gears, and is linked in axial direction with the pinion carrier by means of the axial load carrying bearing, the pinion carrier has two splined crowns, large central wheel has splined crown, output shaft has splined crown, and casing has two splined crowns. The geometrical dimensions and location of the specified tooth-wheels and splined crowns are made such that during axial movement of the pinion carrier the crowns engage, ensuring in series the following modes: reverse movement range, transmission brake, first range, fixed gear between first and second ranges, second range, fixed gear between the second and third ranges, third range, fixed gear between the third and forth ranges, forth range.

EFFECT: increased efficiency.
