20-MODE SINGLE-PASS GEARBOX "CONFIGURATION-20" Russian patent published in 2019 - IPC F16H3/93 F16H37/02 

FIELD: machine building.

SUBSTANCE: invention relates to transmissions with intermediate parallel shafts and gear wheels. 20-mode gearbox comprises drive 0, intermediate A, B, C and output X shafts located parallel to each other in crankcase on bearings. Shafts A and B are opposed relative to the input shaft and are interconnected with it without intermediate shafts. On the shafts gear wheels (1–20) and disk friction control elements (c_01, c_02, c_a1, c_a2, c_a3, c_b1, c_b2, c_c1, c_c2). There is possibility of selective inclusion of gear wheels (1–20) in operation for single-flow transfer of power from shaft 0 selectively directly through shaft A or shaft B to shaft C and further to shaft X. Shaft C is connected to shaft 0 by means of shafts A and B at option. It is possible to impart a set of axes of all shafts, in the cross-section of the gearbox, of various configurations to a choice: crosswise, L- and U-shaped arrangement. 20 modes is provided by the fact that gear wheels, apart from the provided parasitic ones, are distributed on two on shafts 0 and X, five on shaft A, four on shaft B and six on shaft C, and friction elements – two on shafts 0, B, C and three on shaft A.

EFFECT: enlarging layout capabilities of gearbox.
