A torsional vibration damper arrangement includes a vibration damper device (10) having a deflection mass carrier (12) and at least one deflection mass (14) which is supported at the deflection mass carrier (12) such that it can be deflected out of a basic position at a maximum distance from the axis of rotation (A) into a deflection position at a shorter distance from the axis of rotation (A), wherein the secondary side (96) has at least one circumferential supporting element (102, 104; 102′) having at least one circumferential supporting region (106, 108) and a secondary-side mass element (98) which is preferably shaped like an annular disk. First connection elements (118) connect the secondary-side mass element (98) to the at least one circumferential supporting element (98) and to the deflection mass carrier (12).

A torsional vibration damper has a drive-side transmission element and an output-side transmission element rotatable relative thereto that is connected to the drive-side transmission element via a damping device. The damping device includes a first gear element and a second gear element that are in a meshed engagement with each other via a first set of teeth and a second set of teeth, respectively. The sets of teeth for each gear element is provided on the axial sides of the gear elements. A positioning device axially positions the gear elements relative to each other for adjusting the penetration depth of the meshed engagement of the first and second sets of teeth.

A torsional vibration damper has at least one inertia mass, which is connected in a rotation-proof manner to a drive and acts upon an absorption mass. The absorption mass is rotatable relative to the inertia mass and is connected thereto via connecting elements. Associated with the absorption mass is a balancing weight, which is connected via a movement-transmitting transmission to the absorption mass, on the one hand, and to the inertia mass, on the other hand.

A dual-mass flywheel comprises a primary mass (7) which is adapted to be fastened to a crankshaft (3) of an internal-combustion engine concentric to an axis of rotation (1) and a secondary mass (9) which is mounted for rotation relative to the primary mass (7) around the axis of rotation (1). The secondary mass (9) is coupled in a rotationally elastic manner to the primary mass (7) by a torsion-damping arrangement (19). The primary mass has two formed sheet-metal parts (35, 37) which define a cavity (47) to accommodate springs (17) of the torsion-damping arrangement (19) and is provided with supplementary masses in order to increase the moment of inertia. The supplementary masses may be made up of extensions (45, 63) of the formed sheet-metal parts (35, 37) or of additionally welded-on mass-rings (67). In particular, the supplementary masses are located in a region which is generally radially outwardly of the secondary mass (9).

For a dual-mass flywheel in the driving train of a motor vehicle there is proposed a cage-free ball-bearing 9 which has solid balls and is therefore particularly narrow in the axial direction and is sealed in a lubricant-tight manner by a sealing and insulating ring arrangement 31 formed by two ring elements 27, 29. The ring elements 27, 29 are tightly connected to one another axially beyond the ball-bearing 9 and rest with inherent elasticity under bias on the lateral faces of the ball-bearing 9.

A torsional vibration damper for the drive line of a motor vehicle includes an input damper part rotatable about an axis of rotation, an output damper part rotatable about the axis of rotation relative to the input damper part over a limited relative angle of rotation, a spring system coupling the two damper parts together in a rotationally elastic manner, and a friction ring axially clamped between friction surfaces of the damper parts by an axial spring force. The friction ring has a carrier of substantially annular disk-shaped form and consisting substantially of fibrous-material-reinforced synthetic plastic material and friction linings affixed to the carrier. The friction linings are composed of a synthetic plastic material substantially devoid of reinforcing materials and projecting beyond the carrier on both axial sides by a distance corresponding to a predetermined abrasion volume. The carrier of the friction ring is coupled to one of the damper parts.

The torsional shock absorber which is preferably suitable for a dual-mass flywheel comprises an input part (1) and an output part (21) which is rotatable round a common axis of rotation. Between control edges (43) of the input part (1) and control edges (41) of the output part (21), long load springs (23) designed for load running are arranged in an annular channel (15) which surrounds the axis of rotation and couples the output part (21) torsionally elastically to the input part (1). The output part (21) or optionally spring pots (25) provided at the face ends of the load springs (23) carry a peripherally resilient intermediate element (45) which projects beyond the control edges (41) of the part guiding the intermediate element (45) and rests on the control edges (35) of the other part. The control edges of these two parts are spaced from one another in the rest position of the torsional shock absorber, this spacing forming the operating range of the idling suspension. The idling suspension is bridged over once the spacing is used up.

In a double-mass flywheel the flywheels of which are coupled with torsional flexibility by at least one set of at least two helical springs (31, 31'), it is proposed that the end spring (31') of the spring set arranged in a channel (29) encircling the axis of rotation (9) of the flywheels in a circular arc is pivoted to control elements (39, 53) of the flywheels via an endshoe (41). For this purpose, the endshoe (41) and the control elements (39, 53) are provided with guide surfaces which have the cross-sectional shape of a circular segment.
