STEPLESS PLANETARY GEAR TRAIN MECHANISM Russian patent published in 2008 - IPC F16H3/74 F16H37/12 

FIELD: mechanical engineering; vehicle transmissions.

SUBSTANCE: proposed mechanism has housing 1, drive shaft 2 with shoe 3 and extensible lever 4, driven gear 12 with driven shaft 13, articulated carrier 11 with fitted-on distributing cross bar 5 with joint 6 and pressure planet pinion 7, and planetary shaft 8 with planetary gear 9 and planet pinion 10. Extensible lever 4 acts onto distributing cross bar 5. Pressure planet pinion 7 engages with external teeth of planetary gear 9, and planet pinion 10, with torsional engagement with internal teeth of driven gear 12. Speed of rotation of driven shaft 13 is changed by displacement of lever 4 in shoe 3.

EFFECT: enlarged range of change of torques, simplified design of mechanism, reduced cost and provision of smooth operation.
