Abstract: A method for controlling a separating clutch in a power train of a vehicle having a drive motor and a retarder. The clutch is arranged such that a rotor of the retarder is switched into a drive connection with the motor and/or power train via the clutch and a working chamber of the retarder can be filled with an operating medium to build up a braking power such that braking torque is exerted by the retarder onto the power train and/or motor. A control system switches the clutch into a closed or an open position. The switching of the clutch into the closed position occurs depending on an input signal to the controller, and the clutch is switched back into the open position depending on essentially no medium being present in the working chamber of the retarder and that predetermined limits of an operating and/or environmental parameter are not exceeded.

Abstract: A cooling circuit for a motor vehicle having a cooling medium pump that circulates a cooling medium in the cooling circuit having a hydrodynamic retarder. The cooling circuit further includes a main circuit in which the cooling medium pump and a drive motor of the motor vehicle, as well as a heat exchanger are positioned. A secondary branch of the cooling circuit includes a feed that branches off from the main circuit at a branch-off point and ends in the hydrodynamic retarder, and a return which proceeds from the hydrodynamic retarder and ends at a junction location in the main circuit. The return ends upstream of the branch-off location of the feed as viewed in a flow direction of the cooling medium in the main circuit, however on the same side of the cooling medium pump or at the branch-off location of the feed in the main circuit.

Abstract: A vehicle cooling circuit, especially an engine cooling circuit, including a cooling medium pump and a vehicle drive engine and/or other heat-generating assembly cooled by means of the cooling medium. The circuit includes a hydrodynamic retarder with the working medium of the hydrodynamic retarder simultaneously also being the cooling medium of the cooling circuit, and the hydrodynamic retarder operating as the cooling medium pump. The secondary blade wheel is associated with a brake or a drive running counter to the drive of the primary blade wheel in such a way that it can optionally be fixed in a first operating state (braking operation) or be driven counter to the rotational direction of the primary blade wheel and, in a second operating state (pumping operation), can partially or completely be released such that it circulates at the speed of the primary blade wheel or at a specified speed difference slower than the primary blade wheel.
