Title:
HYDRODYNAMIC RETARDER AND METHOD FOR CONTROLLING THE POWER TRANSMISSION OF SUCH A RETARDER
Document Type and Number:
WIPO Patent Application WO/2013/132022
Kind Code:
A3
Abstract:
The invention relates to a method for controlling the power transmission of a hydrodynamic retarder (1), comprising a circulating rotor (2) having vanes and a stator (3) having vanes or a counter-rotating rotor having vanes circulating in the opposite rotational direction to the rotor, which together form a working chamber (4) that can be filled with operating medium through an inlet (6) and that can be emptied through an outlet (6), wherein the working chamber is filled in a brake operation with operating medium and a brake torque is generated with the hydrodynamic retarder and, in a non-braking operation, the working chamber is emptied to a specific residual amount of operating medium and substantially no brake torque is generated with the hydrodynamic retarder. The invention is characterised by the following step: In the non-braking operation, by means of an idling pump (9), operating medium is conveyed from an operating medium reserve, which is provided outside the working chamber in an operating medium reserve tank (7), into the working chamber of the hydrodynamic retarder for the adjustment of the residual amount.
