Beschreibung
Zusammenfassung:	A multi-gear adaptive gear box for a railway vehicle, the gear box comprising a gear box body (4), an input pinion shaft (3), an intermediate gear shaft (21) and a power output shaft (20); the input pinion shaft (3) is mounted on the gear box body (4) by means of N input gears (1, 2); the intermediate gear shaft (21) is mounted on the gear box body (4) by means of M intermediate gears (13, 15, 17), K of the M intermediate gears (13, 15, 17) meshing with gears on the power output shaft (20), wherein N≥2, and M=N+K. The gear box further comprises a gear shifting driving part, and the gear shifting driving part comprises a driving source (11); the driving source (11) is controlled to rotate forwards and backwards so as to displace M-K gears on the intermediate gear shaft (21) to the left and right to separately mesh with N input pinion shafts. The described gear box changes the load point of a vehicle driving system so that a motor and a converter operate within the optimal efficiency ranges, and the adaptive pe
