A start-up and retarder element having a hydrodynamic transfer element (5, 5′) and a planetary gear set (4). The hydrodynamic transfer element (5, 5′) has at least one first functional wheel (11, 11′) and one second functional wheel (12, 12′). The first functional wheel (11, 11′) can be fixed on a stationary component (14) by a single shift element (15). A start-up function or a driving function can be set in which the functional wheels (11, 11′; 12, 12′) of the hydrodynamic transfer element (5, 5′) function as an impeller and a turbine, respectively, of a hydrodynamic start-up element so that a retarder function can be set, or the functional wheels (11, 11′; 12, 12′) of the hydrodynamic transfer element (5, 5′) function as a rotor and a stator, respectively, of a hydrodynamic retarder. |
