The present invention relates to a freewheel damper arrangement (2) for a motor vehicle having a torsional vibration damper (18) having a damper shell (22), spring elements (30) arranged in the damper shell (22) and a damper flange (34) coupled torsionally elastically to the damper shell (22) via the spring elements (30), and a starter freewheel (20) having a first race (58) which can be driven by a starter motor (70) and a second race (60) which is assigned to the damper shell (22), between which clamping elements (62) are arranged. The second race (60) is non-rotatably fastened to the damper shell (22).

The present invention relates to a freewheel-damper assembly (2) for a motor vehicle, having a torsional vibration damper (18) with a primary element (20) which is connectible or connected, on a drive side (36) of the torsional vibration damper (18), to a drive shaft (38), and with a secondary element (22) which is torsionally elastically coupled to the primary element (20) and which is connectible or connected, on an output side (46) of the torsional vibration damper (18) facing away from the drive side (36), to a transmission input shaft (48), and with a starter freewheel (58), via which the primary element (20) can be indirectly or directly driven by a starter motor (60). The starter freewheel (58) is arranged on the output side (46) of the torsional vibration damper (18). The present invention moreover relates to a drivetrain for a motor vehicle having such a freewheel-damper assembly (2).

A pendulum weight for a centrifugal pendulum absorber for a flywheel of a vehicle includes a bearing surface that, when the pendulum weight is mounted radially outside of a central axis of the pendulum absorber, cooperates with a corresponding bearing surface provided on a separate part of the pendulum absorber, with respect to which separate part the pendulum weight is thereby configured to be movable along a predetermined pendulum path. The pendulum weight further includes a pocket formed in connection with the bearing surface, the pocket being configured to receive at least a portion of the separate part when the pendulum weight moves along the pendulum path. The pendulum weight includes an outward portion and a separate inward portion which are assemblable to form the pendulum weight, the outward portion being configured to be located radially outside of the inward portion with respect to the central axis when mounted.

A flywheel arrangement for an engine of a vehicle, includes: a flywheel configured to be connected to a crankshaft of the engine for common rotation around a center axis, a pendulum weight arranged between the center axis and a radially peripheral surface of the flywheel, the pendulum weight being movable with respect to the flywheel along a predetermined pendulum path, a ring member positioned radially outside of the pendulum weight, the ring member being connected for common rotation with the flywheel around the center axis, and at least one pair of cooperating bearing surfaces, each pair of cooperating bearing surfaces including an outer bearing surface provided on the ring member and an inner bearing surface provided on the pendulum weight, the at least one pair of cooperating bearing surfaces together defining the predetermined pendulum path.

A torsional vibration damper and a hydrodynamic torque converter comprising same is disclosed. The torsional vibration damper has an input part which can be rotated about a rotational axis (d) and an output part. An intermediate flange is arranged against a respective spring device, which acts in a circumferential direction, between the input part and the output part, and the intermediate flange is made of two axially spaced interconnected lateral parts, axially between which the input part and the output part are received. In order to improve the loading of the spring devices, the loading of the spring devices by means of the intermediate flange is at least partly provided by loading means arranged between the lateral parts.

A damper device of the present disclosure includes an input element to which torque from an engine is transmitted, an output element, and an elastic body that transmits torque between the input element and the output element. The input element is formed to enclose the elastic body. The output element includes a clearance portion that allows passage of a tool for attaching and detaching the engine and the input element. A sealing member is disposed between the input element and another member other than components of the damper device so as to restrict an entry of foreign substances into the input element on the outside the clearance portion in a radial direction. As a result, assemblability and maintenability of the damper device can be further improved while restricting the entry of foreign substances into the input element formed to enclose an elastic body.
