ABSTRACT:
A combined hydrodynamic retarding brake and oil-cooled driveline flywheel clutch, the clutch (72) being integral with a retarding brake impeller (52) rotatable in a body of oil (58) contained within a housing (22) having a retarder flow circuit (118) therein, the amount of retardation being controllable by varying the amount of oil present in the circuit (118), the retarder impeller (52) operating to supply a flow of cooling oil through the clutch (72), and a clutch brake (102) operable to apply a braking action to the clutch, as the clutch (72) is disengaged operating to stop clutch output, and cut off oil flow to the clutch thereby reducing viscous drag at the clutch.
