MULTI-STAGE GEARBOX

摘要

The multi-stage gearbox with nine forward gears and one reverse gear comprises four planetary gear sets (P1, P2,P3, P4), eight rotary shafts (1, 2, 3, 4, 5, 6, 7, 8) and six gear-shifting elements (03, 04,05, 14, 16, 18), wherein the sun gear of the planetary gear set (P1) is connected to the shaft (5) which engages via the brake (05) with one housing (G) of the transmission, and the connecting bar of the planetary gear set (P1) is connected to the shaft (8) which is connected to the connecting bar of the planetary gear set (P2) and can be connected via the clutch (18) to the drive shaft (1), wherein the drive shaft (1) can be connected via the clutch (16) to the shaft (6) and via the clutch (14) to the shaft (4), wherein the shaft (6) can be connected to the ring gear of the planetary gear set (P3) and the shaft (4) can be connected via the brake (04) to a housing (G) and to the sun gear of the planetary gear set (P4) and to the sun gear of planetary gear set (P3), wherein the ring gear of planetary gear set (P1) is connected to the output drive shaft (2) which is connected to the ring gear of planetary gear set (P2), wherein the connecting bar of planetary gear set (P3) is connected to shaft (7) which is connected to the component which connects the ring gear of the planetary gear set (P4) and the sun gear of the planetary gear set (P2) together and wherein the connecting bar of planetary gear set (P4) is connected to the shaft (3) which is connectable to a housing (G) via the brake (03).
