20090308063 | HYDRODYNAMIC COUPLING - 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. | 12-17-2009 |
20090314598 | HYDRODYNAMIC CLUTCH - A hydrodynamic clutch includes an impeller and a turbine wheel which jointly form a toroidal working chamber that is or can be filled with a working medium. A throttle plate is provided which can be moved in the axial direction of the hydrodynamic clutch in order to be optionally introduced into the working chamber and/or be displaced within the working chamber. The throttle plate extends in the area of a central diameter of the working chamber in the circumferential direction of the hydrodynamic clutch. The intake end of the throttle plate extends parallel or substantially parallel to the axis of rotation of the hydrodynamic clutch from the perspective of an axial section across the hydrodynamic clutch, the working medium flowing against the intake end of the throttle plate in a circular flow. The throttle plate can be moved from an inactive position in which the same has no or only a slight throttling effect on the circular flow of the working medium in the working chamber into an active position in which the same has a comparatively much greater throttling effect on the circular flow, the inactive position being located in the area of the separation gap between the impeller and the turbine wheel. From the perspective of an axial section across the hydrodynamic clutch, the working chamber covers the entire area, without having a center that is delimited relative to the remaining working chamber by way of a wall, such that the throttle plate is directly enclosed by the flow zone of the working chamber in both the active and inactive position of the throttle plate without mounting a wall therebetween. | 12-24-2009 |
20110220442 | Hydrodynamic machine, especially hydrodynamic retarder - The invention relates to a hydrodynamic machine, especially a hydrodynamic retarder, comprising two blade wheels which are opposite of one another in such a way that they jointly form a toroidal working chamber which can be filled with a working medium in order to hydrodynamically transfer torque by means of a cycle flow of the working medium in the working chamber from the first blade wheel to the second blade wheel, with the first blade wheel rotating about a rotation axis and the second blade wheel rotating about the same rotation axis in the same direction of rotation or opposite of the direction of rotation of the first blade wheel, or being held in a stationary manner. | 09-15-2011 |
20130186079 | HYDRODYNAMIC MACHINE, ESPECIALLY A HYDRODYNAMIC RETARDER - A hydrodynamic machine has two blade wheels disposed opposite each other and together forming a toroidal working space. The space can be filled with a working medium to transmit torque hydrodynamically, by circulating the working medium in the space, from the first to the second blade wheel. The first blade wheel rotates about an axis of rotation. The second blade wheel rotates about the same axis of rotation in the same rotation direction as the first blade wheel or opposite thereto, or is held stationary. The blades of each blade wheel extend in an arc from a radially inner blade end on a radially inner wall of the working space to a radially outer blade end on a radially outer wall of the working space, and in plan view in the direction of the rotation axis the arc is in the shape of a circular arc on each blade wheel. | 07-25-2013 |
