AUTOMATIC STEPLESS MECHANICAL TRANSMISSION Russian patent published in 2005 - IPC

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

SUBSTANCE: proposed transmission contains carrier 1 with main planet pinions 6, 7 and additional planet pinion 9, driving central wheel 2 and driven central wheel 3, support wheel 8, input shaft 4 and output shaft 5. Solid planet pinions can play the part of flywheels. Support wheel 8 is secured on hollow intermediate shaft 10 coaxial to input shaft and is coupled with drive of support wheel 8 consisting of three gear wheels 11, 12 and 13. Wheel 13 is intermediate one, being placed between said two wheels, and its axle 14 is installed in transmission housing 15. Two radial axles of carrier 1 are located on one line of axes 0₁-0₁ and they carry main and additional planet pinions installed for independent rotation in opposite directions. Line of axis 0-0 of transmission and lines of radial axes 0₁-0₁ of carrier intersect in central point 0¹ relative to which planet pinions rotate.

EFFECT: simplified design, reduced mass of transmission, provision of possibility of automatically changing of torque depending on load on output shaft.
