A divided flywheel apparatus has a first centrifugal mass connected to a driving mechanism, a second centrifugal mass engaged with the first centrifugal mass my means of a torsional vibration damper, whereby the second centrifugal mass is capable of a limited relative rotation with respect to the first centrifugal mass, and a damping device which contains at least one vibration damper, by means of which, under specified operating conditions, a frictional connection can be established between the two centrifugal masses. The damping device has a sensor apparatus, by means of which the occurrence of at least one measurement corresponding to a specified operating condition can be measured, and by means of a signal transmitted to a switching apparatus, the actuation of the vibration damper can be triggered by means of an actuation device which can be actuated by means of the switching device, resulting in an effective action which is a function of the value measured.

A flywheel device has at least two inertial masses which can rotate relative to one another against the action of elastic elements of a damping device, one of which inertial masses, namely the output-side inertial mass which is farther from a drive system, such as for example the crankshaft of an internal combustion engine, is guided both radially and axially by way of a bearing arrangement with respect to the input-side inertial mass. The bearing arrangement has at least one axial plain bearing and one radial plain bearing. Both plain bearings guide the output-side inertial mass with respect to the input-side inertial mass with a clearance, the size of which is determined so that when a wobbling motion is introduced from the crankshaft to the input-side inertial mass, the output-side inertial mass, under the effect of centrifugal forces, can perform a self-stabilization. The radial plain bearing, to bring it as close as possible to the crankshaft, is engaged in the vicinity of the end of the hub of the output-side inertial mass, which end faces the crankshaft.

Torsional vibration damper for a motor vehicle friction clutch, the torsional vibration damper having a hub with a hub disc, and cover plates located one on either side of the hub disc, which cover plates are fastened together. The cover plates can be rotated with respect to the hub disc against the force of springs by a specified amount, whereby the radial guidance of the parts which can rotate in relation to one another is provided by preferably one cover plate and a bearing element inserted in a central hole of the cover plate. The bearing element permits a limited radial relative movement of the cover plate with respect to the hub, is designed so that in addition to an axial offset, it can also compensate for an angular offset between the crankshaft and the transmission shaft.

A flywheel mass arrangement having a flywheel mass on the driving side, a planetary gear unit having at least one planet carrier provided with at least one planet gear that engages with at least one additional toothed wheel of the planetary gear unit, and with a flywheel mass on the driven side which can be rotationally deflected relative to the flywheel mass on the driving side. At least one of the flywheel masses has a control structure for elastic elements of a damping arrangement which act in the circumferential direction. A mass is provided at the planet gear to project radially beyond the toothing diameter of the planet gear and is arranged at an axial offset relative to at least one additional toothed wheel such as the ring gear or the sun gear of the planetary gear unit, in particular relative to the toothing engagement of the additional toothed wheel with the planet gear.

This invention relates to a clutch disc for a friction clutch in which the connection between the hub and the friction linings is made by several leaf-spring-like elements distributed over the circumference, which elements are fastened in their central area to the hub, are essentially tangential to the axis of rotation and run at some radial distance from the axis of rotation in both directions, and are connected by means of their terminal areas to the friction linings.

A flywheel device has a first flywheel mass that is drivable and rotates around a rotational axis and a second flywheel mass that can be deflected relative to the first at least by a limited rotational angle. The second flywheel mass is drive-connected to the first flywheel mass by a torsional damping device. At least one flywheel mass has a grease chamber which at least partially accommodates the torsional damping device and is equipped with at least one seal against the escape of viscous medium. A first sealing part of the seal is connected to one of the flywheel masses and a second sealing part of the seal is connected to the other flywheel mass. The second sealing part is arranged in a radially offset manner relative to the first sealing part and has at least two fixed arms extending from an annual base in the direction of the first sealing part. Each of the arms is arranged at a predeterminable distance from the side of the first sealing part that faces it and forms, together with the other respective fixed arm and the base, an annular channel holding a highly-viscous medium. The first sealing part is submerged, at least in its region radially adjacent to the second sealing part, in the highly-viscous medium.

A flywheel assembly has a first flywheel which is detachably connected to the crankshaft of a combustion engine, a second flywheel which can be rotated relative to the first, and a torque transformer, such as a hub disc, which is located in a chamber between the two flywheels, which chamber is filled with a viscous medium and which torque transformer is equipped with a torsion damping unit. The chamber is defined on that side facing the second flywheel by a cover plate, which encloses an air channel between it and the second flywheel, which air channel extends radially outward from a ventilation opening in the second flywheel. The torque transformer is provided radially outward from the ventilation opening with an annular surface, which annular surface extends preferably in the axial direction. The cover plate extends with its radially inward end in the radial direction to the annular surface and in the axial direction to the radially outer portion of the torque transformer, whereby the annular surface defines the maximum radial distance from the torque transformer to the ventilation opening for the change of direction of the air channel.

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.

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.
