Hydrodynamic brake device for motor vehicles

摘要

A hydrodynamic brake device for motor vehicles comprises a rotor which is rotatably journalled in a stator shell, the rotor being operably connected to the transmission of the vehicle. The stator shell has a brake fluid inlet and outlet, and a regulator valve is arranged which can be set for regulating the supply of brake fluid to the fluid inlet of the stator shell. A thermostat controls the regulator valve so as to decrease the degree of filling as the temperature of the fluid increases.
