摘要

The gearbox has a drive shaft continuously connected to an element of a first planetary sets, an output shaft continuously connected to a bridge of a second set and a hollow shaft of a third set, shafts continuously connected to an element of the first set and a bridge of the third set, a shaft connected to the hollow wheels of the second and third sets, shafts connected to sun wheels, brakes for coupling shafts to the housing and shaft couplings. The gearbox has a drive shaft (1) continuously connected to an element of a first of 3 planetary sets (P1-P3), an output shaft (2) continuously connected to a bridge of a second set and a hollow shaft of a third set, a shaft continuously connected to an element of the first set, a shaft continuously connected to a bridge of the third set, a shaft connected to the hollow wheels of the of the second and third sets, shafts (3-7) connected to sun wheels, brakes (03, 04) for coupling some shafts to the housing (G) and releasable couplings (14,46,57,67) between shafts.
