Publication number: 20130291677Abstract: A Torsional Vibration Damper includes a hub, a ring, and a rubber member that is compression fitted between the outer surface of the hub and the inner surface of the ring. The cross-sectional profile of the outer surface of the hub and the inner surface of the ring after the assembly of the TVD consists of two concave or convex arcs with their radii such that the cross-sectional profile's gap increases from the center to the sides. This variation of the cross-sectional profile's gap reduces the principal-strain buildup in the rubber, thereby improving the life of the Torsional Vibration Damper. This design also facilitates proper assembly as the components are self aligning.Type: ApplicationFiled: May 3, 2012Publication date: November 7, 2013Applicant: METAVATION, LLCInventors: Suhale Manzoor, Bruce G.

Patent number: 8397602Abstract: A torsional vibration damper includes front and rear hub members with an inertia mass between the two hub members. Annular elastomeric rings are positioned between the front and rear hub members and the inertia mass holding the inertia mass. Fasteners extend through the front hub member, the inertia mass, and fixed to the rear hub member. A clearance between the fastener and the inertia mass allows relative motion to absorb torsional vibration.Type: GrantFiled: June 28, 2007Date of Patent: March 19, 2013Assignee: Metavation, LLCInventors: Bruce G. Christenson, Suhale Manzoor

Patent number: 8117943Abstract: A torsional vibration damper includes a one-piece integral hub and annular inertia mass assembly. Between the hub and the inertia mass are intermediate rings connected integrally with the mass and the hub connected integral spokes. Elastomeric members are compression fitted within spaces formed between the hub and the mass.Type: GrantFiled: September 26, 2007Date of Patent: February 21, 2012Assignee: Metavation, LLCInventor: Suhale Manzoor

Patent number: 8091450Abstract: A torsional vibration damper includes a one-piece integral hub and annular inertia mass assembly. Between the hub and the inertia mass are intermediate rings connected integrally with the mass and the hub connected integral spokes. Elastomeric members are compression fitted within spaces formed between the hub and the mass. With this design, the damper can be formed from a polymeric material with an embedded annular weight.Type: GrantFiled: August 20, 2008Date of Patent: January 10, 2012Assignee: Metavation, LLCInventors: Suhale Manzoor, Bruce G.

Patent number: 7905159Abstract: A torsional vibration damper having a hub carrying a radially projecting flange and an annular inertia mass defining an annular channel encompassing the radially projecting flange and an elastomeric member. An annular compression ring is attached to the opening of the annular channel to axially compress and extrude the elastomeric member to fill the annular channel around the radial flange within the inertia ring. Projections defining an intermittent annular inner rim of the inertia mass extend through openings between the spokes of the hub and cooperate with an annular outer rim of the inertia mass to retain the compression ring.Type: GrantFiled: June 22, 2006Date of Patent: March 15, 2011Assignee: Metavation, LLCInventors: Suhale Manzoor, Bruce Christenson

Patent number: 7802492Abstract: A hub for a vibration damper is formed by shell casting. The hub includes an outer annular surface or rubber diameter. In the casting of the part, the part line is formed along the center of this outer annular surface. The casting gate is also formed on the outer annular surface. The part line divides the outer annular surface into two halves. The surface of these two halves slope slightly away from the part line. When assembled, the elastomeric strip is located between the outer annular surface and inertia ring with edges of the elastomeric member extending up to edges of said casting gate. This, in combination with the different draft angles, maintains the elastomeric member in position during use.Type: GrantFiled: November 2, 2007Date of Patent: September 28, 2010Assignee: Metavation, LLCInventor: Bruce G.
