  • Wet disc friction brake with casing rods extending through stator bores
    Patent number: 4890699
    Abstract: A separable casing or housing for a liquid cooled disc brake assembly wherein the separable parts of the casing are held together by a plurality of circumferentially spaced rods. The casing provides a sealed chamber in which a plurality of axially spaced rotor discs are interleaved with a plurality of stator discs. The rods also extend axially through the stator discs radially inwardly of their peripheral circumference and thus provide a reactive stationary force for the braking action. The rotor discs are splined connected to the rotating wheel that is to be braked.
