The invention relates to a hydrodynamic coupling and a method for operating a hydrodynamic coupling

摘要

Hydrodynamic coupling (1) having a pump wheel (3) as a first blade wheel (2) and with a turbine wheel (5) as a second blade wheel (2), the pump wheel (3) having pump wheel blades (13) connected to a base body of the pump wheel (12) and wherein the turbine wheel (5) with a main body of the turbine wheel (14) connected turbine blades (15), wherein the impeller (3) and the turbine wheel (5) are each rotatably mounted about a central axis (11) and wherein the blades of the Impeller (13) having boundary edges (19) facing the boundary edges (19) facing the blades of the turbine wheel, and wherein from a paddle wheel (2) at least one of the blades has a boundary edge (19) in a first portion (21 ) is divided with a first edge contour (25) and a second portion (23) with a second edge contour (27) and wherein the first (25) and the second edge contour (27) are different.
