- Generic torsional vibration dampers are well known and serve to dampen torsional vibrations of a high-speed internal combustion engine in drive lines of motor vehicles and are screwed to the crankshaft of the internal combustion engine by means of fastening screws of their input part.
- pass-through openings for the screwing tool aligned with the fastening screws are provided in its output part, for example in an output hub.
- torsional vibration dampers have a so-called torque limiting device, which is connected downstream of the spring device effective between the input part and the output part in the circumferential direction and triggers at a predetermined limit torque in order to protect components of the torsional vibration damper and the subsequent drive train from overload.
- torque limiting device is connected downstream of the spring device effective between the input part and the output part in the circumferential direction and triggers at a predetermined limit torque in order to protect components of the torsional vibration damper and the subsequent drive train from overload.
- a torsional vibration damper is described whose torque limiting device contains dry-operated friction linings that are arranged outside the annular chamber.
- the output hub of the torsional vibration damper rotates relative to its input part, so that the fastening openings and the penetration openings may no longer be aligned with one another.
- a renewed alignment of the fastening screws and access openings may be necessary.
- the output part must be rotated in relation to the input part against the action of the spring device or the torque limiting device must be loosened using appropriate tools in order to rotate the output hub.
- the object of the invention is to develop a generic rotary vibration damper.
- the object of the invention is to propose a torsional vibration damper with a torque limiting device that allows the output hub to be rotated with little force and without additional tools if there are openings that are not aligned with the fastening screws.
- the proposed torsional vibration damper is used to isolate torsional vibrations, in particular in a drive train with an internal combustion engine subject to torsional vibrations.
- the torsional vibration damper is received by means of fastening screws on the crankshaft of an internal combustion engine and is thus arranged to be rotatable about an axis of rotation, in particular the axis of rotation of the crankshaft.
- the torsional vibration damper contains an input part with fastening openings and optionally a reinforcing ring for the fastening screws, which is made of disc parts in a transformative manner and can form a primary flywheel mass. For this purpose, further mass elements can be provided radially on the outside.

- the output part can contain a flange part with radially he extended arms, which engages between the adjacent end faces in the circumferential direction.
- a torque limiting device is provided to limit the peak moments transmitted via the torsional vibration damper.
- the torque limiting device can be formed, for example, as a friction device with a friction plate biased between two side parts with friction linings arranged on both sides, which are axially biased between the side parts by means of a plate spring to a predetermined Rutschmo element. If a given permissible limit torque exceeds the frictional torque, the torque limiting device slips by limiting the transmittable torque of the torsional vibration damper to protect its components and components of the drive train following the torsional vibration damper.
- the torque limiting device is preferably arranged radially inside the spring device and outside the annular chamber, which is greased in the preferred manner, in order to prevent the torque limiting device from being contaminated with lubricant of the annular chamber.
- the side parts of the torque limiting device can be connected to the output hub and the friction plate can form the flange part for acting on the spring device on the output side.
- the torque limit limiting device and the output hub is provided an axially releasable and axially prestressed toothing by means of a pre-tensioning means. This means that a component of the torque limiting device and the output hub are interlocked with one another in the circumferential direction and that these teeth are axially pretensioned and thus secured during normal operation of the torsional vibration damper.
- the toothing can be released if necessary by releasing the toothing against the effect of the preload by axially displacing the output hub and, for example, rotating the output hub into the aligned position of the access openings with the fastening openings and restoring the toothing.

- the other side part can have corresponding recesses for forming the riveting.
- the leaf springs can be fixed at the end of the output hub and by means of elongated holes on the torque limiting device, so that a partial circumferential rotation of the output hub within the elongated holes relative to the torque limiting device is enabled when the toothing is disengaged.
- a centrifugal pendulum is preferably assigned to the output part. The centrifugal pendulum is preferably arranged outside the annular chamber and its pendulum mass carrier is connected to the output hub.
- the pendulum mass carrier can be formed from several carrier parts in which the pendulum masses are encapsulated so that a burst protection for the pendulum masses and parts of the pendulum bearings is formed on the outside and dirt is at least largely kept away from the pendulum masses.
- the pendulum mass carrier is considered part of the output hub, so that the leaf springs can be fixedly rotated at the end of the torque limiting device and by means of elongated holes also on the pendulum mass carrier to a limited extent and can thus be accommodated on the output hub.
- a sub-assembly can be formed from the centrifugal pendulum, the output hub and the leaf springs, which is connected to the torque limiting device after the completion of the torsional vibration damper on the leaf springs.
- the rivets of the side parts can be riveted by means of corresponding penetration openings provided in the centrifugal force pendulum and in the entrance part.
