ABSTRACT:
A liquid-cooled heavy duty brake assembly including a number of rotor discs for cooperation with stator discs for braking an external rotating body connected to the rotor discs which is to be selectively braked. The rotors and stators are normally biased apart, but are movable toward each other along the direction of the axis of rotation of the rotor discs in order to effect braking. The casing for the assembly is closed and includes heat exchanging portions around the periphery thereof, including fins extending inwardly toward the axis of rotation of the rotor discs, and the casing is filled to less than capacity with cooling liquid. A closed circulatory loop is provided so that cooling liquid is pumped outwardly by the relative rotation of the rotor discs with respect to the stator discs, toward the heat exchanging portions of the casing, splashing thereagainst and frothing, and then passing inwardly toward the axis of rotation of the rotor discs through interior passageways formed in at least some of the stator discs.
