摘要

The gear box device (1) has drive unit (2A) operatively connectable to input shafts (EW1,EW2) and countershaft (VW). The input shafts display nine translations for forward motion and one translation for reverse motion over wheel sets (R3-RR) by switching of switching devices (SE1-SE7). The switching devices (SE1-SE4,SE6,SE7) represent first two translations through connection of preset wheel sets and switching element side switching. A preset wheel set of switching devices (SE2,SE3,SE6,SE7) are coupled with input shafts.
