BRAKE DEVICE WITH RETARDER, AND METHOD FOR REGULATING SUCH A BRAKE DEVICE

摘要

The invention relates to a brake device with a hydrodynamic retarder, comprising at least one rotor blade wheel and one stator blade wheel (2, 3) which are arranged in a common housing and which together form a toroidal working chamber (4) that can be filled with a working medium for the braking operation of the retarder and emptied again for the non-braking operation of the retarder. The hydrodynamic retarder also comprises an external cooling circuit line (15) which runs from the working chamber (4) to a cooler (19) and back. In order to achieve an improved braking power, a temperature measurement Tcircuit is temporarily used which is carried out by a temperature sensor that is positioned such that a temperature can be measured in the working chamber (5) using the temperature sensor in order to regulate the hydrodynamic retarder at least during the braking operation.
