Abstract
A stator wheel for a hydrodynamic torque converter comprises a stator wheel hub arrangement and a plurality of stator wheel blades arranged successively in the circumferential direction of the stator wheel hub arrangement. Each stator wheel blade has a radial inner flow-around profile area and a radial outer flow-around profile area such that a flow-around profile in the radial outer flow-around profile area differs from a flow-around profile in the radial inner flow-around profile area. A first cover ring surrounds the stator wheel hub arrangement and is connected with the stator wheel blades is arranged in radial transition area between the radial inner flow-around profile area and the radial outer flow-around profile area
