Hydrodynamic retarder

The invention relates to a hydrodynamic retarder having a first blade wheel (25) and having a second blade wheel (27) concentric thereto, together forming a hydrodynamic circuit (41) and being grouped about a common rotary axis. Each blade wheel (25, 27) is made of a base body (19, 29) and a blade a...

Beschreibung
Zusammenfassung:	The invention relates to a hydrodynamic retarder having a first blade wheel (25) and having a second blade wheel (27) concentric thereto, together forming a hydrodynamic circuit (41) and being grouped about a common rotary axis. Each blade wheel (25, 27) is made of a base body (19, 29) and a blade arrangement (21, 33) fixed thereto comprising a plurality of blades (23, 35). The hydrodynamic circuit (41) is supplied by means of a fluid inlet (43), while the fluid removal from the hydrodynamic circuit (41) is performed by means of a fluid outlet (45). The fluid inlet has an inlet spiral (110) enabling tangential fluid flow and the fluid outlet has an outlet spiral (112) enabling tangential fluid flow (126). At least one inlet spiral (110) is associated with a flow guide guiding the fluid into the hydrodynamic circuit (41) with at least one axial component.
