Abstract

A tubular hub member receives a shaft and is surrounded by a housing formed by a base section coupled to a cup-shaped closure section. The hub member defines an inlet passage for circulating cooling oil and supports a set of brake discs which interfit between a set of brake plates supported by pins projecting inwardly from the base section. An annular thrust plate is supported by the base section for axial movement and carries a set of compression springs which urge the thrust plate for clamping the brake plates and discs against a pressure plate mounted within the closure section. An annular electrical coil and support body are mounted by screws and spacer sleeves within the closure section, and an annular armature plate is supported by the sleeves for axial movement adjacent the end wall of the closure section. A set of actuating pins extend axially between the armature and thrust plates through the coil body and pressure plate, and the armature plate cooperates with a portion of the closure section to define a variable oil recirculating passage. Axial movement of the armature plate displaces cooling oil into the inlet passage to provide a surge of cooling oil during braking. The pressure plate has passages which are aligned with recesses in the coil body for recirculating cooling oil when the brake unit is positioned with a vertical axis, and diametrically opposed rotatable members provide for manually releasing the brake unit and for automatic reset to inactive positions.
