ABSTRACT:
The multi-step reduction gear comprises one drive shaft and one driven shaft, three planetary spider sets (P1,P2,P3), the first planetary spider set (P1) defining a fixed input ratio, at least six rotatable shafts (1, 2, 3, 4, 5, 6) and at least five shift elements (03, 04, 13, 16, 45) so that six forward gears and one reverse gear can be implemented, the drive shaft (1) being connected with the sun wheel of the first planetary set (P1), the spider of the first planetary set (P1) with the housing, the driven shaft (2) with the ring gear of the second planetary set (P2) and the spider of the third planetary set (P3), and the shaft (3) being permanently connected with the spider of the second planetary set (P2) and the ring gear of the third planetary set (P3). The shaft (4) is permanently connected with the sun wheel of the second planetary set (P2), the shaft (5) being permanently connected with the ring gear of the first planetary set (P1) and the shaft (6) permanently connected with the sun wheel of the third planetary set (P3). The planetary sets (P1,P2,P3) are coupled by means of shafts (0, 1, 2, 3, 4, 5, 6) and shift elements (03, 04, 13, 16, 45).
