Abstract
There is disclosed herein a clutch-brake unit having a clutch disc pack and a separate brake disc pack which are designed for selective actuation by a single piston arrangement to transmit rotational driving forces from an input shaft to an output shaft via the clutch disc pack and to brake rotation of the ouput shaft via the brake disc pack as desired. An integral oil pump is provided on the input shaft and cooperates with portions of the housing to provide a high volume centrifugal pumping action to continuously circulate oil through passages provided in the housing, input shaft, output shaft and across the clutch and brake disc pads so as to cool them. In one embodiment, the integral oil pump includes a pump chamber separate from the central cavity formed by the housing and also working chambers for the clutch and brake disc packs are separated from the central cavity by annular inner housings. Provisions are also incorporated whereby the oil flow may be directed to external auxiliary apparatus such as oil cooler if desired.
