摘要

The invention relates to a range gearbox of planetary type, designed to be attached to a vehicle gearbox, a so-called base gearbox. The annulus or gear ring of the planetary gear set is non-rotatably joined to a shift sleeve, through which the annulus can be locked either to a coupling ring securely joined to the front housing end wall of the range gearbox, or to a coupling ring which is non-rotatably mounted on the input shaft of the range gearbox. The shift sleeve serves as an annulus carrier and displaces the annulus axially during the shift movement.
