Abstract

A starting element for transmitting torque from a drive-side rotational input (14) of the starting element to a driven hub (8) includes a hydrodynamic torque converter (4) which has a turbine coupled to the driven hub (8) so as to be fixed with respect to rotation relative to it and which comprises a turbine shell (56) with turbine blades (22) arranged therein. A maximum extension of the turbine shell (56) opposite an axial direction (12) terminates at a first axial position (53), and an impeller (20) located opposite the turbine in the axial direction (12). A stator (24) is arranged between the turbine and the impeller (22) and is coupled via a stator flange (58) to a freewheel (52) adjoining the driven hub (8) in an axial direction (12). A center of the freewheel (52) is located at a second axial position (54). A difference between the first axial position (53) and the second axial position (54) is greater than a predetermined minimum value.
