The transmission enables to transmit the power from a driving-shaft (2) to a driven shaft (18) at different speeds by means of gears (19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 39, 40, 41, 42, 43, 46, 50), synchronized clutches (36, 37, 38, 44, 45, 48) and switchable friction clutches (5, 6), forms two power-transmission branches and transmits power only by one of the branches at a time. One friction clutch (5) and at least one synchronized clutch (36) arranged one after the other in the power flow direction operate on each power transmission branch. The transmission comprises a main gear (8, 9), a range gear train (12) and a reverse gear (13). Both friction clutches (5, 6) are mounted on the driving shaft (2). |
