Patent number: 7484434Abstract: A torsional vibration damper is provided which includes a primary mass, a secondary mass, and a damping unit. The damping unit includes a plurality of coil springs, a pair of end guides, and a friction member. The plurality of coil springs are situated in series and disposed one after the other within the divided portions of the ring-shaped chamber. The pair of end guides are slidably disposed within each divided portion of the ring-shaped chamber and support outer ends of the end coil springs among the plurality of elastic members. The friction member is slidably disposed between neighboring elastic members, and it is configured to be rubbed against the primary mass in response to compressions of the coil springs such that a friction force is generated in proportion to a relative rotation between the primary and secondary masses.Type: GrantFiled: June 30, 2004Date of Patent: February 3, 2009Assignee: Hyundai Motor CompanyInventors: Jae Hoon Jung, Tae Han Jee, Young Rae Song

Patent number: 7426984Abstract: A torsional vibration damper includes: a primary mass defining a substantially, ring-shaped chamber that is divided into at least two portions; a secondary mass relatively rotatably connected to the primary mass; and a plurality of damping units disposed in the divided portion of the ring-shaped chamber for coupling the primary and secondary masses to each other in a rotatable elastic manner. Each of the damping units includes a plurality of coil springs, and outer and inner wedge-shaped friction guides. The coil springs are situated in series and disposed one after the other within the divided portions of the ring-shaped chamber. The outer and inner wedge-shaped friction guides face each other along facing surfaces thereof. Each of the facing surfaces of the outer and inner wedge-shaped friction guides are entirely slanted with respect to a radial direction of the primary mass.Type: GrantFiled: August 9, 2005Date of Patent: September 23, 2008Assignee: Hyundai Motor CompanyInventors: Tae Han Jee, Jae Hoon Jung, Young Rae Song

Patent number: 7364511Abstract: A torsional vibration damper includes: a primary mass adapted to be coupled to an engine crankshaft and defining a substantially ring-shaped chamber that is divided into at least two portions; a secondary mass relatively rotatably connected to the primary mass and connectable with a clutch; and a damping unit for coupling the primary and secondary masses to each other in a rotationally elastic manner. The damping unit includes a plurality of coil springs, a pair of end guides, and a friction guide that is disposed between neighboring coil springs and provided with an outer circumferential surface configured to be rubbed against an outer wall of the ring-shaped chamber. An oil groove is formed on the outer circumferential surface of the friction guide and at least a portion of the oil groove is formed to be slanted with respect to a circumferential direction of the ring-shaped chamber.Type: GrantFiled: August 9, 2005Date of Patent: April 29, 2008Assignee: Hyundai Motor CompanyInventors: Tae Han Jee, Young Rae Song, Jae Hoon Jung

Patent number: 7241224Abstract: A torsional vibration damper includes a primary mass defining a ring-shaped chamber, a secondary mass relatively rotatably connected to the primary mass, and a damping unit for coupling the primary and secondary masses to each other in a rotationally elastic manner. The damping unit comprises a plurality of coil springs, a pair of end guides, and a friction member slidably disposed between neighboring coil springs. The friction member is configured to be rubbed against at least one of an inner wall and an outer wall of the ring-shaped chamber in response to compressions of the coil springs such that a friction force is generated in proportion to a relative rotation between the primary and secondary masses as well as to a rotational speed thereof.Type: GrantFiled: December 30, 2004Date of Patent: July 10, 2007Assignee: Hyundai Motor CompanyInventors: Young Rae Song, Tae Han Jee, Jae Hoon Jung
