ABSTRACT:
Multiple gear transmission comprising input and output shafts (1, 2), three planetary sets (P1, P2, P3), six rotatable shafts (1, 2, 3, 4, 5, 6) and six shifting elements (03, 04, 05, 14, 16, 56). Selective engagement of the shifting elements produces seven forward and two reverse gears. The input shaft is connected with the sun gear of the first planetary set (P1), the output shaft with the web of the second planetary set (P2), the third shaft (3) with the sun gears of second and third planetary sets (P2, P3), one shaft (4) connects the web of the first planetary set (P1) with the ring gear of the third planetary set (P3), one shaft (5) is connected with the ring gear of the first planetary set (P1), one shaft (6) connects the web of the third planetary set (P3) with the ring gear of the second planetary set (P2).
