FIELD: machine building.
SUBSTANCE: invention relates to transmissions of type 13R12. Three links of simple three-link planetary mechanisms (PM) - sun gear, epicyclic wheel and carrier with satellites - have shafts with toothed rims and eight clutches at input and output of two PM.
EFFECT: compactness of planetary gearbox 13R12 type (thirteen forward gears and twelve reverse gears) at reduction of overall dimensions and metal consumption.
