Abstract

A hydrodynamic torque converter, having a housing arrangement is filled with fluid and an impeller with a plurality of impeller vanes successively arranged in circumferential direction around an axis of rotation, a turbine in a housing interior, the turbine has a plurality of turbine vanes successively arranged in circumferential direction around the axis of rotation, and a stator with stator vanes successively arranged in circumferential direction around the axis of rotation. The impeller, the turbine and the stator form a fluid circulation torus with a torus diameter Td considered radially with respect to the axis of rotation, an outer radius Ra with respect to the axis of rotation, and a torus width considered in direction of the axis of rotation.
