AUTOMATIC STEPLESS MECHANICAL TRANSMISSION Russian patent published in 2005 - IPC

FIELD: mechanical engineering; automotive industry; machine-tool building.

SUBSTANCE: proposed transmission contains coaxial input shaft 1 and out-put shaft 2, bevel driving wheel 3 and driven wheel 4, additional support central bevel gear 11 and auxiliary support central bevel gear 10, carrier 5 with radial axles on which main planet pinion made up of two wheels 6 and 7, additional planet pinion 8 and auxiliary plant pinion 9 are mounted. Additional support and auxiliary support wheels 11, 10 are secured on their additional hollow intermediate shaft 12 and auxiliary hollow intermediate shaft 18, respectively. Shafts 12 and 18 are installed coaxially to shafts 1 and 2, being connected to them by drives. Transmission and conversion of torque at all duties is provided by braking carrier 5 caused by change of direction of vectors of angular momentum of planer pinions of larger mass at rotation relative to central point 0¹ of intersection of line O-O of transmission and radial axes 0₁-0₁ of carrier 5.

EFFECT: improved reliability of power coupling of input and output shafts with conversion of value of torque and speed depending on value of load applied to shaft.
