FIELD: transport.SUBSTANCE: invention relates to gearboxes of vehicles. Gearbox comprises three series-connected modules. Driven shaft of previous module is driving shaft of next module. Each module includes planetary cylindrical helical gearbox consisting of drive shaft, crown and sun gears, carrier and satellites. Automatic switching system includes friction coupling, drive discs of which through splines are coupled with crown gears, and driven discs through housing of coupling with carrier, centrifugal weights with springs and automatic system for controlling state of sun gears.EFFECT: simplified design, higher reliability and reduced cost.1 cl, 1 dwg |
