Patent ID: 8230752

Claim:
A group transmission comprising: a multi-stage main transmission (HG) having either three forward gears or four forward gears, a splitter group (VG) being connected upstream of the main transmission (HG), and a two-stage range-change group (BG) being connected downstream of the main transmission (HG), and at least one of the multi-stage main transmission (HG), the splitter group (VG) and the range change group (BG) having shifting clutches, such that the splitter group (VG) being connected, via a controllable separator clutch, to a drive motor in the form of an internal combustion engine, the main transmission (HG) and the range-change group (BG) being of synchronized or unsynchronized design, and the shifting clutches of two respective transmission ratio steps in at least one of the multi-stage main transmission (HG), the group (VG) and (BG) are respectively combined in a common shifting packet with two shift positions and a neutral position, wherein in the main transmission (HG) the shifting clutches associated with a lowest transmission ratio step (G 1 ) and with a highest transmission ratio step (G 4 or G 3 ) are combined with one another in a common shifting packet (S 1 / 4 or S 1 / 3 ).
