Abstract:
A torque converter, comprising a plurality of converter components including:a converter housing rotatably mounted about an axis of rotation and having a cover and a pump wheel connected in a radially outer area;a turbine wheel rotatably arranged within said converter housing for rotating about said axis of rotation relative to said converter housing, said turbine wheel having a turbine wheel shell with a plurality of circumferentially arranged turbine blades and a turbine wheel hub connected to a radially inner region of said turbine wheel shell;a bridge coupling operatively arranged between said turbine wheel and said cover for selectively connecting said turbine wheel to said cover; anda torsional vibration damper operatively arranged for transmitting torque from said turbine wheel hub to one of said bridge coupling and said turbine wheel shell, wherein said torsional vibration damper comprises a damper hub element having control regions facing in the circumferential directions, first and second covering element sections having control regions arranged on both circumferential sides of said hub element, and damping springs arranged between adjacent control regions, and wherein said first and second covering element sections are mounted on said turbine hub, wherein said said turbine wheel hub comprises a recess extending substantially annularly about the axis of rotation and open substantially toward an axial direction, said first and second covering element sections comprising a blind end wall section and a radially outer wall section of said recess, wherein said radially outer wall section of said recess comprises a free end having a radially inwardly projecting section for axially holding said damping springs.
