F16D25/00Fluid-actuated clutches

F16D25/02with means for actuating or keeping engaged by a force derived at least partially from one of the shafts to be connected F16D25/04in which the fluid actuates an elastic clutching, i.e. elastic actuating member F16D25/042the elastic actuating member rotating with the clutch F16D25/044and causing purely axial movement F16D25/046and causing purely radial movement F16D25/048the elastic actuating member not rotating with a coupling part F16D25/06in which the fluid actuates a piston incorporated in F16D25/061the clutch having interengaging clutch members F16D25/062the clutch having friction surfaces F16D25/063with clutch members exclusively moving axially F16D25/0632with conical friction surfaces F16D25/0635with flat friction surfaces F16D25/0638with more than two discs F16D25/064the friction surface being grooved F16D25/065with clutching members having a movement which has at least a radial component F16D25/08with fluid-actuated member not rotating with a clutching member F16D25/082the line of action of the fluid-actuated members co-inciding with the axis of rotation F16D25/083Actuators therefor F16D25/085the clutch actuation being of the pull type F16D25/086the clutch being actuated by a push rod extending coaxially through the input or output shaft F16D25/087the clutch being actuated by the fluid-actuated member via a diaphragm spring or an equivalent array of levers F16D25/088the line of action of the fluid-actuated members being distinctly separate from the axis of rotation F16D25/10Clutch systems with a plurality of fluid-actuated clutches F16D25/12Details not specific to one of the before-mentioned types F16D25/123in view of cooling and lubrication F16D25/126adjustment for wear or play F16D25/14Fluid pressure control
