| The invention relates to a parallel shift transmission comprising a split group (2) and a range group (3), each of which is separated into two parallel transmission branches (5, 6). One of the transmission branches (5, 6) can be selected by actuating a corresponding powershift element such that a rotational movement of a driveshaft (1; 25) can be transferred at one of a plurality of gear ratios of the split group (2), wherein the gear ratio is transmitted to countershafts (7 to 10; 13 to 16; 7, 9, 20, 21, 22, 23) according to the selection of one of the transmission branches (5, 6), and the rotational movement of the driveshaft can then be converted into a rotational movement of an output shaft (4; 19) such that the rotational movement is transmitted at one of a plurality of range ratios of the range group (3). The gear steps (A1 to A8) that define the individual gear ratios are distributed to the two transmission branches (5, 6) in a corresponding gear ratio sequence in an alternating manner, while each of the range ratios is determined by shifting a corresponding group step of a plurality of group steps (B1.1 to B3.2) of the range group (3). The aim of the invention is to be able to guide an auxiliary output through the transmission system with little effort. This is achieved in that the powershift elements are designed as individual clutches (11, 12), each of which is arranged in the corresponding transmission branch (5, 6) between an output-side countershaft (7, 9; 14, 17) of the split group (2) and a drive-side countershaft (8, 10; 15, 18; 20, 22) of the range group (3). | ||||||

A twin clutch type transmission in which, when establishing a reverse gear position, the driving force of an engine (E) is transmitted to driven wheels (W, W) via the path: even-numbered gear clutch (Ce) → second input shaft (13) → second input shaft gear (22) → idle shaft second gear (42) → idle shaft first gear (41) → first countershaft first gear (23) → first countershaft (14) → first countershaft second gear (24) → third countershaft second gear (34) → first speed-third speed synchronizing device (36) → third countershaft (16) → third countershaft third gear (35) → second output shaft gear (46) → second output shaft (19) → final drive gear (44) → fmal driven gear (48) → differential gear (47). When establishing a first speed gear position by engaging an odd-numbered gear clutch (Co), the whole of the driving force transmission path on the downstream side of the first countershaft first gear (23) is shared with that when establishing the reverse gear position, thus enabling the weight and dimensions of the transmission to be reduced effectively. |
