<p>The multi-step gear contains drive shaft (1) and output shaft (2) arranged in housing (G), four planet sets (P1,P2,P3,P4), seven hinged shafts as well as logic elements, brakes (03,04,05) and clutches (13,17) whose selective transmission ratios work between drive shaft and output shaft, so that atleast seven forward gears and one reverse gear are realized. The drive shaft is constantly connected with second planet set and with first clutch with the third shaft and removably connectable with second clutch with the seventh shaft. The third shaft is constantly connected with third planet set and removably connected with first brake and with the housing.</p> |
