摘要

The motor vehicle change-speed gearbox of modular construction is partic. for farm and road tractors. In addition to the main gearbox it has an epicyclic intermediate one, one, and one or more auxiliary drives, and the annulus of the epicyclic gearbox can be coupled to the main one. The epicyclic gearbox(8) precedes the main change-speed one(19) in the direction of power flow, and is coupled via a double selection clutch(17) allowing changing under load to the input shaft(18) of the main one. Brakes(13, 14) can be applied separately or together to the annulus(12) and the planet carrier(11) of the epicyclic gearbox.
