发明名称 ROTATIONAL COUPLING DEVICE
摘要 A rotational coupling device is provided in which an armature (30) affixed to a hub (22) rotating about a rotational axis is drawn in a first axial direction towards a rotor (26) disposed about, and rotatable relative to, the hub upon energization of an electromagnetic circuit including the rotor, the armature and a field shell housing (48) a conductor (50) to cause frictional engagement of clutch plates (36, 40, 34) affixed to the rotor and hub and rotatably couple the rotor and hub. In accordance with one aspect of the invention, the rotor and/or hub may include means (90, 92, 94, 156, 158, 160) for limiting movement of the clutch plates in a second axial direction to maintain spacing between the clutch plates. In another aspect, the rotor may be made from multiple members and one member (164) may provide both a pole forming part of the circuit and a braking surface (172) configured to engage a brake plate (52) in the device upon deenergization of the circuit. In another aspect, the rotor may define a chamber (134) in which the armature and clutch plates are disposed that defines a sump containing a fluid with the field shell and conductor isolated from the fluid. In yet another aspect, the device may include means, such as a tube (44, 46) having one end submerged in the fluid and extending through an aperture (180) in the armature, for transporting fluid from the sump to the clutch plates.
