Description

Fliehkraftpendeleinrichtunq

The invention relates to a centrifugal pendulum device for the eradication of torsional vibrations, preferably in a drive train of a motor vehicle, comprising at least one Tilgermassentrager rotatable about a rotation axis and at least one arranged on the absorber mass absorber absorber mass, wherein the absorber mass relative to the absorber mass carrier along a raceway is limited pivot.

In corresponding centrifugal pendulum devices exist operating conditions in which a damping mass strikes against the end of the track on Tilgermassentrager. This leads to a sometimes significant noise and to a deterioration of the decoupling. Therefore, stop the absorber masses at the end of the raceways to prevent.

From WO 201 11λ 57255 A1 a centrifugal pendulum device is previously known. The centrifugal pendulum device comprises a damper mass carrier rotatable about an axis of rotation and at least one absorber mass pair arranged thereon consisting of two absorber masses located axially opposite one another. The absorber mass pair and the absorber mass carrier have raceways in which a rolling element is received, so that the absorber mass pair is limitedly pivotable relative to the absorber mass carrier.

In order to prevent the absorber mass pairs or the rolling elements abut the ends of the raceways, a guide element is arranged on at least one side of the absorber mass carrier between two circumferentially adjacent absorber masses, which serves as a spring stop. However, it is disadvantageous that the guide element acts as an energy storage and thus accelerates the absorber masses in the opposite direction. Furthermore, it is disadvantageous that this construction is complex and thus expensive to manufacture.

In DE 10 201 2 220 960 A1 a centrifugal pendulum device for damping torsional vibrations is also shown. The centrifugal pendulum device comprises a about a rotation axis rotatable Tilgermassenträger and at least one on the Tilger- mass carrier under centrifugal force displaceably arranged Tilgermassen pair. For displaceable arrangement of Tilgermassenpaares on Tilgermassenträger a pendulum role is provided. To decelerate the Tilgermassepaar at the end of the track, a clamping spring means is arranged, which acts on the spherical roller with a force. In this construction is also disadvantageous that no damping of the kinetic energy, but only an energy storage by the clamping spring means. The absorber masses are thus accelerated in the opposite direction by the clamping spring device acting as an energy storage device. Furthermore, this construction is also very complicated and therefore expensive to manufacture.

Other devices known from practice have rubber elements which are arranged on spacer bolts of the absorber masses, which contact at the end of the track of the absorber mass with a contour of the absorber mass carrier. The rubber elements also have the disadvantage that they do not dampen the movement of the absorber masses, but act as energy storage and therefore accelerate the absorber masses in the opposite direction.

Finally, it is known to design centrifugal pendulum devices with hydraulic stop dampers, so as to avoid striking the absorber masses on the absorber mass carrier. However, hydraulic stop dampers are disadvantageous in that they are often not sufficiently dense and therefore maintenance-intensive. Furthermore, hydraulic stop dampers are characterized by a complicated and costly production.

An object of the present invention is therefore to provide a centrifugal pendulum device in which a striking of the absorber masses on the absorber mass carrier is reliably prevented. Another object of the present invention is to provide a centrifugal pendulum device which is simple in construction and can be manufactured at a low cost. Another object of the present invention is finally to provide an alternative centrifugal pendulum device. The present invention solves the problems with a centrifugal pendulum device for damping torsional vibrations, preferably in a drive train of a motor vehicle, comprising at least one Tilgerma- ssenträger rotatable about an axis of rotation and at least one arranged on the Tilgermassenträger absorber mass, the absorber mass relative to the absorber mass carrier along a track can be pivoted, characterized in that at least one friction device is arranged, wherein the friction device can be brought into contact with the absorber mass, so that the absorber mass can be braked by the friction device at least at one end region of the raceway.

One of the advantages achieved with this is that the kinetic energy of the absorber mass can be converted into heat energy so that there is no storage of the kinetic energy. The absorber mass can therefore be reliably braked by means of simple design and striking of the absorber mass at an end region of the raceway is virtually eliminated. Another advantage is that it is a very simple construction in this arrangement, so that the centrifugal pendulum device is simple in construction and thus inexpensive to produce.

Further advantageous embodiments, features and advantages of the invention are described in the subclaims.

Appropriately, the friction device is acted upon in the axial direction with a force and rotatable in the circumferential direction. The friction device can thus convert the kinetic energy of the absorber mass by friction into heat energy, in that the absorber mass rotates the friction disk in the circumferential direction. As a result, the kinetic energy of the absorber mass is not stored temporarily, but converted into heat energy, so that an effective deceleration of the absorber mass takes place.

Advantageously, the friction device is designed as a friction disk or as a friction ring or as a friction segment. Through the realization of a friction disc or a

Friction ring or a friction segment can be particularly easy and inexpensive to produce the friction and arrange in the centrifugal pendulum device. Conveniently, a driver is formed on the absorber mass and a recess on the friction device, or a driver is formed on the friction device and a recess is formed on the absorber mass. With this configuration, the absorber mass can be brought into contact with the friction device with structurally simple means.

Advantageously, the driver and the recess are arranged in the same axial plane, wherein the driver is arranged radially within the recess and wherein the recess is larger in the circumferential direction than the driver. Due to the arrangement of driver and recess in the same radial plane, wherein the driver is provided radially within the recess, the entire device is very small. By the recess in the circumferential direction is formed larger than the driver, there is a so-called. Clearance range in which the absorber masses are not braked by the friction device. Only after this clearance angle range has been exceeded is the friction device in contact with the absorber mass. It is particularly advantageous if the contact between friction and damping mass takes place only in the protective area of the absorber system, i. in the angular region where the order is detuned toward a smaller order to protect the absorber system.

Conveniently, the friction device is arranged radially inside or radially outside of the absorber mass. A friction device arranged radially inside the absorber mass has the advantage that the entire device is small in the axial direction and therefore requires only little space. A friction device arranged radially outside the absorber mass additionally has the advantage that the friction device is easily accessible, so that maintenance is particularly easy to carry out.

Advantageously, the friction device is arranged axially parallel to the absorber mass. Such a construction offers the advantage that the centrifugal pendulum device takes up a minimum of space in the radial direction.

Conveniently, the axis of rotation of the friction device corresponds to the axis of rotation of the absorber mass carrier. By realizing a single axis of rotation for the friction direction and the Tilgermassentrager the entire construction is extremely simple and thus produce the centrifugal pendulum device cost.

Advantageously, the axis of rotation of the friction device is offset parallel to the axis of rotation of the absorber mass carrier. By this construction, the axis of rotation of the friction device can be realized independently of the axis of rotation of the absorber mass carrier. Consequently, the axis of rotation of the friction device can be optimally adapted to the friction device.

Expediently, a respective absorber mass is arranged on both sides of the absorber mass carrier in the axial direction, so that these absorber masses form a absorber mass pair. This arrangement has the advantage that the absorber masses are particularly easy and safe to be arranged on the Tilgermassenträger.

Advantageously, several Tilgermassenpaare, preferably four Tilgermassen- pairs, arranged circumferentially next to each other. Thus, the centrifugal pendulum device can be almost arbitrarily adapted to the order to be removed, so that ideally an erosion of torsional vibrations is possible.

Advantageously, the absorber mass is arranged in the axial direction between two absorber mass carriers. This design offers the advantage that the absorber mass carriers lead the absorber mass between them so that the absorber masses can be positioned extremely accurately.

Advantageously, a plurality of absorber masses, preferably four absorber masses, are arranged in the axial direction between two absorber mass carriers and in the circumferential direction next to one another. This has the advantage that several absorber masses can be positioned as accurately as possible with respect to the absorber mass carriers and can be tuned to the order to be eliminated.

Conveniently, a respective friction device per absorber mass or per Tilgermassenpaar is arranged. The advantage of this construction is that the Tilgermassen not be influenced by the friction device in opposite movements.

Advantageously, at least one spring element, preferably two spring elements, arranged, wherein the spring elements are supported on the one hand on the at least one friction device and on the other hand on the at least one Tilgermassenträger. Consequently, a provision of the friction device is possible in its initial position, so that the friction device is in any operating condition in a defined position relative to the absorber mass.

Conveniently, the at least one friction device serves as a support ring for the at least one absorber mass. As a result, the absorber mass is radially supported with the friction device, which depending on the material properties of the support ring, the movement of the absorber mass can stop sufficiently soft, so that no mechanical damage or noise.

Advantageously, the friction device is centered on the absorber mass carrier via an inner diameter of the friction device. With this configuration, the friction device is positioned in a simple manner relative to the absorber mass carrier and ensures a particularly effective deceleration of the absorber masses

In the region between -a and a, the so-called. Clear angle range, the absorber mass 3 is thus not braked by the friction device 7. In this case, the centrifugal pendulum device 1 is tuned such that the clearance angle range, i. the magnitude of the angle a is so great that deceleration of the absorber mass 3 takes place only in the region in which the order is detuned in the direction of a smaller order in order to protect the centrifugal pendulum device 1.

Or .beta. And the angle .alpha. Or -a , Therefore, the restoring moment is not reduced when swinging back the absorber masses. A deceleration of the absorber masses takes place exclusively in the range between α and ß or -a and -ß.

In summary, the present invention offers the advantage that the kinetic energy of the absorber masses can be converted into heat energy and there is no storage of kinetic energy. Thus, striking the absorber masses at the end of the career is almost impossible, so that no disturbing noises verur- be gentle. Finally, the centrifugal pendulum device is realized with structurally simple means and therefore inexpensive to manufacture.
