  • Patent number: 10408281
    Abstract: A rotation transmission device is provided in which a collision sound by an armature and a rotor is less likely to occur, and further the armature is stably attracted to the rotor. A buffer is provided between the armature and the rotor. The buffer is constituted by a metal annulus axially movably supported by the armature, and a rubber annulus configured such that as the armature approaches the rotor, the rubber annulus is axially compressed by the metal annulus and the armature. The rubber annulus has different axial thicknesses at different circumferential locations thereof such that when the degree of axial compression of the rubber annulus is large, the rubber annulus is axially compressed in its longer circumferential area than when the degree of axial compression of the rubber annulus is small.

  • Patent number: 10203005
    Abstract: A passive opening transmission clutch system includes a backing plate having multiple tab slots, each of the tab slots having a tapered wall. A first reaction plate has multiple first tapered spline teeth oriented transverse to a plane of the first reaction plate. The first tapered spline teeth are positioned at least partially in individual ones of the tab slots in a clutch disengaged condition. The first tapered spline teeth when displaced further into the tab slots and toward the backing plate define a clutch engaged condition. A first friction plate is in frictional contact with the first reaction plate in the clutch engaged condition, the first friction plate when rotated generating a rotational force on the first reaction plate. The rotational force acts against the first tapered spline teeth to induce the first reaction plate to slidably move away from the backing plate.
