FIELD: transport.

SUBSTANCE: gearbox consists of differential splitter mounted in clutch case. Clutch input shaft is engaged with the engine while output shaft makes the main reduction gear primary shaft, said reduction gear being composed by several pairs of gearings fitted on parallel shafts. Besides, it comprises synchromeshes and differential splitter with integrated reverse gear. Splitter input shaft is composed by main reduction gear secondary shaft while planet carrier makes gearbox output shaft. Differential splitter consists of input gear shaft, two-rim pinions fitted on axles fitted in plant carrier, output gear making the main reduction gear input shaft, free running coupling arranged between planet carrier and output gear, two band brakes driven by hydraulic cylinders acting at differential splitter planet carrier. Differential splitter with integrated reverse gear consists of two-rim and idler wheel fitted on axle mounted in splitter plant pinion that makes gearbox output shaft, crown gear with synchromesh arranged at crown wheel hub for throwing in neutral, forward and step-down gear, crown wheel doubling as reverse IN clutch.
