The designations "input part" and "output part" relate in particular to the direction of the power flow from the travel drive. The terms "axial", "radial" and "circumferential" relate to the direction of extension of the axis of rotation of the flywheel assembly, unless indicated to the contrary or otherwise not from the context. The "axial direction" then corresponds to the direction of extension of the axis of rotation. "radial" is then the direction perpendicular to the direction of extension of the axis of rotation and intersecting the axis of rotation. The "circumferential direction" then corresponds to the direction of a circular arc about the axis of rotation.
The flywheel assembly may be housed on, e.g. screwed to, a crankshaft of an internal combustion engine. The flywheel assembly may have a flange member. For example, the flange part of the flywheel assembly made of sheet material has corresponding openings. For a secure connection, a reinforcing ring can be attached to the flange part and/or can be screwed together with the flange part to the crankshaft. The flange member may have a shell-like shape including a bottom section and a rim section. The bottom section may extend at least substantially in a radial direction. The edge section may extend at least substantially in the axial direction. The flange part may have a toothed ring, a toothed ring or a driving ring. The toothed ring, the toothed ring or the driving ring can be arranged radially on the outside on the flange part.
The flywheel assembly may have at least one centrifugal pendulum device. The flywheel assembly may have at least one centrifugal pendulum device arranged on the flange part. The centrifugal pendulum device may have a pendulum mass carrier and at least one pendulum mass movably arranged on the pendulum mass carrier. The flange part and the pendulum mass carrier can be fixedly connected to one another, in particular riveted or screwed. In the case of a rotating flywheel assembly, the centrifugal force field of the rotating flywheel assembly can be defined by a centrifugal force field of the rotating flywheel assembly. The pendulum mass can be suspended pivotably on the pendulum mass carrier by means of circumferentially spaced pendulum supports. The pendulum mass can be formed from one or more, for example two, axially superposed pendulum mass parts. The pendulum masses can be arranged on both sides of the pendulum mass carrier.

The spring may be implemented as a compression spring. The spring damper arrangement can have one, two, three, four or more springs. The damper input component and/or the damper output component may have a recess for a spring. The mechanical accumulator may absorb energy when the torsional vibration force exceeds the force of the spring and the damper input member and the damper output member rotate relative to each other such that the spring compresses. At least one mechanical energy store can output energy when the torsional vibration force is lower than the force of the spring, so that the damper input part and the damper output part are rotated back relative to each other again.
The damper may be provided with an additional hysteresis element. For example, the damper can have a damper friction device. The damper friction device may have at least one friction ring or disc. The damper friction device may have a disk spring diaphragm and/or a compression spring.
The flywheel assembly may have a torque limiter. A torque limiter may act between the flange member and the damper input member. The torque limiter can be used to protect flywheel components, in particular the energy accumulator of a spring-damper device, against excessive torques. Excessive torque is the torque that causes damage to the flywheel assembly. Excessive torques can occur, for example, when the spring is locked and can also be referred to as a percussion torque. The torque limiter may be used to limit the torque transferable by the flywheel assembly to a torque that is operationally reliable to transfer.

The friction device may have at least one first friction element. The friction device may have at least one second friction element. The at least one first friction element and/or the at least one second friction element may be used for a frictional or force-fitting connection of the input part and the output part of the limiter to one another. The at least one first friction element and/or the at least one second friction element can be embodied as a friction lining. By means of the friction device, torques up to a maximum torque can be transmitted in a friction-locking and/or force-locking manner. When the friction device is loaded with a torque greater than the maximum torque, the frictional connection between the limiter input part and the limiter output part can be overcome, so that the torque transmission is reduced or interrupted. The at least one first friction element and/or the at least one second friction element may be assigned to the damper input part or the flange part.

The at least one second friction element can be arranged axially between the housing part and the cover part of the vibration damper and/or can bear against the housing part or the cover part. The at least one second friction element can be fixedly connected, in particular riveted or screwed, to the support part. The at least one second friction element can be arranged, for example, axially on the output side on the flange part or on the support part or can bear against it. At least one second friction element can be arranged axially between the flange part and the support part and/or can bear thereon. The at least one second friction element may serve as a counter element with respect to the at least one first friction element. The at least one second friction element may be a counter plate. The at least one first friction element may abut against the at least one second friction element. The at least one first friction element can form a frictional and/or force-fitting connection and/or form a friction pair with the at least one second friction element. Two first friction elements may be provided. The at least one second friction element may be arranged axially between the two first friction elements.

The spring component can be supported on a support component of the flywheel arrangement, a support element of the support component or a support section of the damper input component and/or can be fixed thereto. The spring member may load the at least one first friction element and the at least one second friction element with respect to each other, e.g. a force, e.g. a normal force. In this way, the at least one first friction element and the at least one second friction element are loaded and/or pressed against one another with a defined normal force, which determines the friction in the circumferential direction. The at least one first friction element may act between the spring member and the at least one second friction element. The at least one first friction element may form a friction pair with the spring member and the at least one second friction element. The friction device may have a support member, such as a support disk. The support member may act and/or be arranged axially between the flange member and the support member, axially between axially spaced support elements of the support member or axially between axially spaced support sections of the damper input member. The support member may act and/or be arranged between the at least one first friction element and a support member of the flywheel assembly or a support section of the damper input member. The support member may act and/or be arranged between the at least one first friction element and the spring member.

The support part can be fixedly connected, in particular riveted or screwed, to the damper input part.
The damper may have a rotation restricting portion. The rotation limitation unit is designed to connect the damper input part and the damper output part to one another, in particular in a form-locking manner, starting from a specific angular position. The rotation limiting portion may be formed by a stopper, for example an end stopper. The stop can be embodied as a projection and/or a recess. The housing part and/or the cover part of the vibration damper can have a stop embodied as a projection and/or a stop embodied as a recess. The projection can engage axially and/or radially into the recess. The stop can act in the circumferential direction. The stop can intervene according to the course of the spring characteristic. The blocking torque can be absorbed via the stop. The blocking moment can occur, for example, when the spring becomes blocked, for example as a result of an ignition interruption, i.e. the spring coils overlap and contact one another in the direction of the screw axis.
The drive train may be a hybrid drive train. The drive train may be a drive train of a hybrid vehicle. The drive train may have an electric drive and an internal combustion engine-operated drive. The electric drive can be operated as an electric motor and/or as a generator. The internal combustion engine-operated travel drive may have a crankshaft.

The drive train may have a transmission. The transmission may be a shifting transmission. The transmission may be a continuously variable transmission. The drive train may have a hybrid transmission, such as a dedicated hybrid transmission. The drive train may have at least one drivable wheel. An electric drive and/or an internal combustion engine-operated drive can be used to drive at least one wheel. The drive train may have an auxiliary drive assembly.
In summary, and in other words, the invention makes it possible in particular to provide a rigid flywheel for a drive train, for example a hybrid drive train, which flywheel has a torque limiter, a centrifugal pendulum and a downstream damper, for example an internal damper. The damper may also be referred to as a predamper. The flywheel may also be referred to as a flywheel assembly. A low-friction and cost-effective damper/predamper according to the clutch disc principle/predamper principle can be mounted or integrated on and/or directly in the driven hub of the rigid flywheel. The damper can be held on the driven sleeve such that the blocking torque can be absorbed via the end stop. The end stop can intervene according to the course of the spring characteristic. The damper on the driven disk hub can be assigned additional hysteresis elements, for example those used in clutch disk dampers. A torque limiter may be mounted on the damper that reduces the over-torque when needed. The torque limiter may be mounted between the rigid flywheel and the support member. The support member may be used as a transmitter board for the motor control sensor. The support member may be mounted by means of a riveted or screwed connection. This enables the torque limiter to be removable and replaceable after operation or damage. A rigid flywheel may be secured to the crankshaft. The rigid flywheel can carry a centrifugal pendulum.
The rattling noise, in particular during the increase and decrease of the torque of the internal combustion engine, is avoided or at least reduced by the invention. A high degree of isolation is ensured. The reliability of torque limitation is improved. The transferable torque can be limited to the torque that can be reliably transferred in operation. Damage to the flywheel arrangement or the spring damper arrangement as a result of excessive torque is reliably prevented. Avoiding the impact moment.

The support part 314 serves to surface-uniformly apply a force to the first friction element 308 by means of the spring part 312. The support member 314 is fixedly riveted or screwed to the support member 302. In addition, reference is made in particular to fig. 1 and the associated description.
By "may" is meant, inter alia, optional features of the invention. There are therefore also modifications and/or embodiments of the invention which additionally or alternatively have a corresponding feature or features.
If necessary, individual features can be selected from the combinations of features disclosed above and combined with other features to define the claim object, with possible structural and/or functional relationships between these features being resolved.
