GEARBOX UNIT COMPRISING TWO PLANETARY GEAR SETS AND NO MORE THAN FOUR SHIFTING DEVICES, AND MOTOR VEHICLE

摘要

The invention relates to a gearbox unit (1) for a hybrid motor vehicle (2), said unit comprising: a planetary gearbox (3), said planetary gearbox (3) being equipped with a first planetary gear set (4) and a second planetary gear set (5), and an input shaft (7) of the planetary gearbox (3), which shaft is prepared for coupling to an internal combustion engine (6), can be coupled to a first planet carrier (8) that supports the first planetary gear set (4) and/or to a first sun gear (9) that meshes with the first planetary gear set (4); an electric machine (10); and no more than four shifting devices (11, 12, 13, 14), each of which forms a brake, a clutch or a one-way clutch and is operatively used to shift different gear ratios, wherein a rotor shaft (16) of the electric machine (10) is permanently connected for conjoint rotation with a second sun gear (17) that meshes with the second planetary gear set (5). The invention also relates to a motor vehicle (2) comprising an internal combustion engine (12) and said gearbox unit (1).
