Abstract
A method for tractive force interruption-free shifting of a hybrid drive comprising combustion engine (), electric engine (), main gear (HG) comprising two parallel connected partial gears, output shaft (), and first and second planetary gears (PG, PG). Each partial gear having either first hollow gear input shaft () or second solid gear input shaft (). The first planetary gear (PG) is connected to the main gear (HG) as the range group, with main gear (HG) comprising at least five gear planes (R-R) and at least four shifting elements (S-S). The electric engine () is connected to carrier (ST) of the range group (PG) and the output shaft () so that the electric engine () supports tractive force while the range group (PG) is shifted, and the fifth gear plane (R) is connected to carrier (ST) of range group (PG) and thus can be shifted under load.
