Multi-speed planetary gearbox i.e. automatic gearbox, for e.g. commercial vehicle, has rotatable shaft connected with internal gear of first planetary gear set, where shaft is formed as driveshaft

摘要

The gearbox has four planetary gear sets (P1-P4) and eight rotatable shafts (1-8), where the fourth shaft is connected with sun gears of the first and the third sets and coupled to a housing (G) by a brake (04). A bar of the third set is connected with the third shaft that is coupled to the housing by another brake (03). The bar of the second set is connected with the seventh shaft that is detachably connected with the first shaft by a clutch (17). The first shaft is formed as a driveshaft, and connected with an internal gear of the first set.
