  • Driveshaft coupling with elastomer damper
    Patent number: 4551115
    Abstract: A driveshaft coupling particularly suitable for vehicles characterized by its vibration damping ability. Drive and driven members in concentric relationship about an axis of rotation include spaced non-concentric surfaces between which elastomer elements are located. Relative rotation between the members compresses the elastomers to transfer torque. The members also include engageable abutment surfaces directly transferring torque metal-to-metal upon the occurrence of predetermined elastomer deformation.

  • Air cooled damper
    Patent number: 4307627
    Abstract: An air cooled torsional vibration damper utilizing air passages for producing circulation of cooling air. An inertia ring of a composite construction includes a high thermal conductivity metal adjacent a heat producing elastomer, and a denser metal ring adds mass. Air passages, including a radial passage portion, are defined in the inertia ring adjacent the engaging surfaces of the ring components.
