ELECTROMAGNETIC CLUTCH WITH ANTI-JAM CAM ACTUATION Abstract of the Disclosure A cam actuated clutch of the type in which an armature is drawn into engagement with pole faces formed on a rotatable input member by energization of an electromagnetic coil. The armature is drivingly engaged with an input member by a plurality of balls cooperating with conical recesses formed in opposing radial surfaces, while the torque transmitted through the clutch by engagement of the armature causes a camming action between balls and recesses by relative rotative and axial movement between the member surfaces formed with the recesses, urging the armature into tight engagement with the pole faces. The anti-jam feature consists of an arrangement for limiting the camming forces generated between the balls and the recesses by creating a spring force resisting the relative axial movement between an intermediate member formed with one set of conical recesses, with the opposing set of conical recesses formed in the armature. A positive stop prevents relative movement after a predetermined relative travel between the intermediate member and the armature to limit the camming force to the level produced by the spring upon engagement of the positive stop. The positive stop acts to limit relative rotation by pins passing through openings in the armature sized to allow a predetermined extent of relative rotation to limit the camming action. The intermediate member comprises a spline plate, splined to the input member so as to be rotatably connected thereto while accommodating the axial movement caused by the camming actuation.
