Abstract
A range gearbox of planetary type designed to be joined to a vehicle gearbox, a so-called basic gearbox. The ring gear of the planetary gear set is non-rotatably jointed to an engaging sleeve by which the ring gear can be locked to an engaging ring fixed to the rear end wall of the gearbox, or to an engaging ring joined to the planetary gear carrier. The engaging sleeve serves as a ring gear carrier displacing the ring gear axially when shifting range modes.
