Hydrodynamic clutch arrangement

A hydrodynamic torque converter, comprising:

• a housing configured to be filled with a fluid;
• an impeller arranged in the housing, the impeller comprising a plurality of impeller vanes successively arranged in circumferential direction around an axis of rotation;
• a turbine arranged in the housing, the turbine comprising a plurality of turbine vanes successively arranged in circumferential direction around the axis of rotation;
• and
• a stator arranged in the housing, the stator comprising a plurality of stator vanes successively arranged in circumferential direction around the axis of rotation,
• wherein the impeller, the turbine, and the stator form a fluid circulation torus that has a substantially circular outer contour having
• a torus diameter Td of the cross-section of the torus considered radially with respect to the axis of rotation,
• an outer radius Ra with respect to the axis of rotation, and
• a torus width B considered in direction of the axis of rotation, wherein the hydrodynamic torque converter satisfies at least one of:
• 0.25<Td/Ra<0.45,
• 0.25<B/Ra<0.45,
• zp>35, where zp is the quantity of the plural impeller vanes, and
• zt>31, where zt is the quantity of the plural turbine vanes,
• wherein:
• 0.8<B/(Ra−Ri)<1.2,
• where Ri is an inner torus radius of the fluid circulation torus with respect to the axis of rotation.
