Power-takeoff gear box i.e. three-speed gear box, for tractor, has pin shaft arranged offset of axis of input shafts, two gear stages coupled with one of input shafts and wheels, and third gear stage coupled with other shaft and wheels

摘要

The gear box has two input shafts (2, 3), which are arranged concentrically to one another, where one of the input shafts is designed as a hollow shaft through which the other input shaft passes. A dual clutch device (4) i.e. moving off clutch, is provided between a drive shaft (1) and the input shafts. A pin shaft is arranged offset of an axis of the input shafts. Two spur gear stages (12, 13) linked with power-takeoff (PTO) (8) are coupled with the former input shaft and fixed wheels (5-7, 11). A third PTO linked spur gear stage (14) is coupled with the latter input shaft and wheels. An independent claim is also included for an agricultural commercial vehicle.
