AUTOMATIC GEARBOX WITH MOVABLE SHAFTS Russian patent published in 2003 - IPC

FIELD: mechanical engineering; transport. SUBSTANCE: invention can be used in fixed ratio transmissions. Said automatic gearbox with movable shafts contains housing, drive shaft, driving gear cluster moving translationally along splined of drive shaft by means of control device drive mechanism, driven shaft moving translationally together with bearing supports square to its axis in guides in spaces of gearbox housing, intermediate shaft rotation in bearing supports and translationally moving together with supports square to its axis in guides in spaces of gearbox housing, idler gear engaging with driving and driven gears of separate step of each cluster being rigidly secured on intermediate shaft. Driving and driven gears of each step have conical part, and idler gear has conical parts at both sides. At moment of gearshifting, conical parts of driving and driven gears of definite step and conical parts of idler gear interact. EFFECT: simplified design of automatic gearbox. 8 dwg
