MECHANICAL AUTOMATIC STEPLESS GEARBOX Russian patent published in 1997 - IPC

FIELD: automotive industry; automobiles, tractors, machine tools; self-adjusting mechanisms of transmissions of self-propelled vehicles and drives of processing machines and machine tools. SUBSTANCE: movable epicycle of second train has second gear rim and two outlet of differential train: central sun gear and movable epicycle are intercoupled by closing member made in form of set of planet pinions movable installed on shafts of planet pinions of first two trains. Some planet pinions of set are engaged with second rim of epicycle and with central sun gear of additional third train secured on output shaft; second planet pinions of set are engaged with central sun gear of generator installed coaxially and movably on output shaft and arranged between second and third trains; central sun gears of second differential train are provided with parallel eccentric tenons on end faces. Tenons are installed movable diametrically opposite in eccentric holes of central sun gears of first planetary and second differential trains. Cylindrical torsional springs are fitted on pointed to each other cylindrical smooth sections of central sun gears of first planetary train, second differential train and generator. EFFECT: enlarged operating capabilities. 2 dwg
