The gearbox has first crown wheel rotating together with second satellite carrier, which rotates together with output shaft. The second crown wheel rotates together with first satellite carrier, which can be connected with primary shaft or to gearbox housing through controlled couplings. The gearbox has a primary input shaft (A1) driving a parallel output shaft (A2) through crown wheels and epicyclic gear trains with planetary gears and satellite carriers. Its first crown wheel (C1) rotates together with a second satellite carrier (PS2), which rotates together with the output shaft (A2). The second crown wheel (C2) rotates together with the first satellite carrier (PS1), which can be connected with the primary input shaft (A1) or to the gearbox (20) housing through controlled couplings (CC, CD). The second planetary gear (PL2) can be connected to the primary input shaft or to the gearbox housing by other couplings (CA, CB), and the first planetary gear (PL1) can be connected to the primary input shaft or gearbox housing through couplings (CE, CF).
