发明名称 AUTOMATIC GROUP TRANSMISSION
摘要 An automated group transmission having a multi-stage main transmission (HG), a splitter group (VG) connected upstream from the main transmission (HG) and a two-stage range-change group (BG) connected downstream of the main transmission (HG), such that the splitter group (VG) is connected, via a controllable separator clutch, to a drive motor. The main transmission (HG) and the range-change group (BG) are of either a synchronized or an unsynchronized design and the shifting clutches of two respective transmission ratio steps, in at least one of the partial-transmissions (VG, HG, BG), are respectively combined in a common shifting packet with two shift positions and a neutral position. To speed up most range shifts, it is provided that in the main transmission (HG) the shifting clutches associated with the lowest transmission ratio step (G1) and with the highest transmission ratio step (G4 or G3) are combined in a common shifting packet (S1/4 or S1/3).
