Patent ID: 8601803

Claim:
A hydrodynamic clutch having constant or variable filling of a work medium, the hydrodynamic clutch comprising: a pump wheel having a pump wheel blading; a turbine wheel having a turbine wheel blading, wherein the pump wheel and the turbine wheel form a toroidal work space, wherein the toroidal work space is fillable with the work medium for a torque transmission; a storage space for receiving the work medium from the toroidal work space, the storage space having a connection that conducts the work medium to the toroidal work space, wherein the work medium is conducted from the storage space into the toroidal work space to increase the torque transmission and from the toroidal work space into the storage space to reduce the torque transmission, and wherein a ratio of a volume of the toroidal work space to an installation volume of the hydrodynamic clutch is greater than 0.26 and less than 0.5, the installation volume of the hydrodynamic clutch being defined by a cylinder volume having a constant diameter, wherein the cylinder volume has an external diameter corresponding to a maximum external diameter of the hydrodynamic clutch and an axial length corresponding to a maximum axial extension of the hydrodynamic clutch; and a clutch hub implemented as a hollow shaft, wherein the clutch hub can receive a shaft.
