Abstract
A hydrodynamic coupling has an impeller and a turbine wheel that together form a toroidal working chamber. Viewed as an axial section through the hydrodynamic coupling the working chamber has a circular or essentially circular cross-section with a convexity in the axial direction on the circumference in the radially outer area of said turbine wheel and/or in the radially inner area of said impeller.
Claims14
A hydrodynamic coupling, comprising:
- an impeller including a first radially inner terminating end;
- and
- a turbine wheel including a second radially inner terminating end, said impeller and turbine wheel together forming a toroidal working chamber, viewed as an axial section through the hydrodynamic coupling said working chamber having one of a circular and an essentially circular cross-section with a convexity which extends said working chamber in an axial direction, said convexity being on a circumference in at least one of a radially outer area of said turbine wheel and a radially inner area of said impeller, no convexity being on a circumference of a radially inner area of said turbine wheel, said first radially inner terminating end and said second radially inner terminating end aligning with one another.
A hydrodynamic coupling, comprising:
- an impeller;
- and
- a turbine wheel, said impeller and turbine wheel together forming a toroidal work space, said work space, when viewed in an axial cross-section through the hydrodynamic coupling, having one of a circular and an essentially circular cross-section with a bulge which extends said work space in an axial orientation, said turbine wheel forming a single said bulge in said axial orientation, said single bulge formed by said turbine wheel being at a perimeter of a radial outer section of said turbine wheel.
