ABSTRACT:
A hydraulic or fluid-power brake is disclosed. The brake comprises a stationary housing, and a rotor shaft journaled in the housing. A number of rotor discs are carried on the shaft for rotation therewith, but they are adapted for axial sliding motion on the shaft, as by a spline arrangement. A number of stator discs are interleaved with the rotor discs and are carried on torque pins mounted in the housing for sliding motion in the direction of the rotor shaft axis, but are secured against rotational movement with the rotor shaft and rotor discs. Biasing means such as springs urge the stator discs into braking engagement with the rotor discs. To relieve this braking action and permit free shaft rotation, a primary piston, having an annular skirt surrounding the rotor discs, engages one stator disc to apply a force urging that stator disc in a direction opposite to the force applied by the biasing means so as to release the braking action. A secondary device is included for opposing the primary piston action so as to permit the biasing means to urge the stator discs into braking engagement with the rotor discs. This secondary means can be independently energized, by fluid pressure or mechanical means as by a service brake. In one embodiment, this secondary means includes a piston carried in an annular cylinder chamber; the piston is located to apply an annular force against the stator disc in opposition to the force applied by the primary piston.
