A torsional vibration absorber for a vehicle is provided. The torsional vibration absorber including a front pilot bearing adapted to couple with a vehicle shaft. A spring member is coupled to the front pilot bearing. An inertia ring having an inner surface is operably coupled to the spring member, wherein the front pilot bearing is centrally disposed along the length of the inertia ring. A rear pilot bearing is adapted to couple with the vehicle shaft, the rear pilot bearing having a portion adjacent the inner surface at one end of the inertia ring.

A torsional vibration damper is provided that is capable of increasing torsional rigidity without increasing a size of an elastic member in a radial direction. A torsional vibration damper includes a boss member and a disk plate provided coaxially with each other; an elastic member being elastically deformable in a rotation direction of the boss member; a cam member rotating integrally with the boss member; a torque transmission member transmitting rotation torque between the boss member and the disk plate; and a socket member provided between the torque transmission member and the elastic member and having a contact surface coming in contact with the torque transmission member. The torque transmission member is capable of entirely reciprocating in a radial direction of the boss member in accordance with rotation of the cam member, and elastically compresses the elastic member when it moves outward in the radial direction of the boss member.

A torsional vibration damper for transferring torque between a first and a second rotatable element, having a rotatable pressure plate to transfer the torque from the first element, a rotatable output element to transfer the torque to the second element, and a vibration damper element to transfer the torque between the pressure plate and the output element, where the vibration damper element includes an energy-storing spring system. A driving element is formed in a single piece on the pressure plate to fit against the spring system.
