VEHICLE TRANSMISSION Russian patent published in 2000 - IPC

FIELD: transport engineering; transmissions. SUBSTANCE: proposed transmission has gearbox combined with transfer case which include two differentials, two planetary mechanisms, drive shafts of driving axles, gears and clutch sleeves. Gearshift sleeve is arranged between gears on hub of primary shaft. Other gearshift sleeve is arranged between freely fitted gears engaging with primary shaft gear cluster. Three relatively engaged clutch sleeves are placed between gears secured in pairs on drive shafts of sun gears of planetary mechanisms and freely fitted gears in meshing with primary shaft gear cluster. Two more relatively coupled clutch sleeves are placed between planetary mechanisms and differentials. Each differential connects transfer case with final drives of rear driving wheels of one of vehicle sides or with final drive of one wheel and also with final drive of front driving wheel of vehicle other side. Lock-up clutch is fitted on rim of carrier of each differential. EFFECT: improved performance characteristics at simplified design and reduced metal usage. 4 dwg
