Abstract:
1. A multiple stage transmission in planetary design, for an automatic transmission for a motor vehicle, the multiple stage transmission comprising a drive shaft ( 1 ) and a driven shaft ( 2 ) accommodated within a housing (g), first, second and third planetary gear sets (P 1 , P 2 , P 3 ), at least four rotatable shafts ( 3 , 4 , 5 , 6 ), at least six shifting elements ( 03 , 04 , 13 , 16 , 45 , 56 ) including first and second brakes ( 03 , 04 ) and first, second, third and fourth clutches ( 13 , 16 , 45 , 56 ) which are selectively engageable for producing different reduction ratios between the driven shaft ( 1 ) and the driven shaft ( 2 ) so that the multiple stage transmission is able to implement seven or eight forward gears and at least one reverse gear; the drive shaft (
