Description

The present invention relates to an arrangement comprising at least one axis of rotation and, arranged coaxially thereto, a first component and a centrifugal pendulum. The first component is B. a torsional vibration damper or a clutch disc or an additional component that is non-rotatably connected to the torsional vibration damper or clutch disc (i.e. non-rotatable).

A torsional vibration damper is used to damp rotational irregularities in a drive shaft that can be driven by an internal combustion engine, for example a crankshaft. A torsional vibration damper is a damping device that is used in the torque flow from the input shaft to an output shaft, e.g. B. a transmission input shaft, is arranged and has a set up for receiving torque primary side and provided for passing the torque to the output shaft secondary side.

A damping device is a torsional flexibility introduced in a targeted manner in a drive train excited with periodic disturbances. The aim here is to shift the disruptive vibration resonances that occur in various operating situations to a speed range that is as low as possible below the operating speeds. In particular, therefore, the primary side is due to the vibrations relative to the secondary side and z. B. twisted against a spring force. Vibration resonances that remain in the operating speed range are dampened by an external or integrated friction device whose friction torque has to lie within defined limits.

Such a torsional vibration damper is arranged in particular in a drive train of a motor vehicle between an internal combustion engine and a transmission. The primary side of the damping device is connected in particular to a clutch disk, which is arranged in a clampable manner between a pressure plate and a counterplate. If the pressure plate is shifted towards the counter plate, the clutch disc is clamped between them and a torque can be introduced into the torsional vibration damper.

A centrifugal pendulum is intended in particular to reduce engine-excited torsional vibrations. The centrifugal pendulum comprises at least one flange or two flanges (as a flywheel) and a plurality of pendulum masses that are movably arranged on the flange or between the flanges. When the centrifugal pendulum is in operation, the pendulum masses can be used to generate a restoring moment that counteracts a rotational non-uniformity.

A centrifugal pendulum, e.g. B. according to DE 10 2006 028 552 A1 , e.g. B. via at least two pendulum masses, which are guided along a track or guides by means of (pendulum) rollers on a carrier element or two carrier elements, also referred to as (FKP) flange. The pendulum masses can oscillate along their tracks in the field of centrifugal acceleration if they are excited by the torque fluctuations of an internal combustion engine. Due to these vibrations, energy is withdrawn from the exciter vibration at suitable times and fed back in again, so that the exciter vibration calms down, i.e. the centrifugal pendulum pendulum acts as an absorber. Since both the natural frequency of the centrifugal pendulum oscillation and the excitation frequency are proportional to the speed, the damping effect of a centrifugal pendulum can be achieved over the entire frequency range.

From the DE 10 2006 028 552 A1 It is known to connect a centrifugal pendulum to a hub of a clutch disc in a rotationally fixed manner via a caulking connection.

From the DE 10 2012 214 813 A1 is known to connect a centrifugal pendulum by means of a slip clutch backlash with a clutch disc.

In the DE 10 2014 219 271 A1 a centrifugal pendulum is riveted to the main damper flange of a torsional vibration damper.

In the DE 10 2018 109 071 A1 further solutions for connecting the centrifugal pendulum to a torsional vibration damper are proposed, e.g. B. by welding or screwing.

In the DE 10 2015 211 899 A1 a torsional vibration damper designed as a pendulum rocker damper is described.

In a caulked connection of a centrifugal pendulum with a hub, the hub is locally plastically deformed. This can result in deformation of the internal teeth on the centrifugal pendulum.

A riveted connection to the flange of a torsion damper requires a lot of space. The spacer bolts reach through a side panel, so that recesses are required in the side panel for this. Furthermore, recesses for the riveting tool are necessary in the opposite side panel.

Proceeding from this, the present invention has the object of at least partially overcoming the problems known from the prior art and in particular of specifying an arrangement in which the centrifugal pendulum is arranged without play on a first component, the disadvantages of the known connections between the centrifugal pendulum and of the first component can be avoided.

This object is achieved with an arrangement according to the features of independent claim 1. Further advantageous developments of the invention are specified in the dependent claims. The features listed individually in the dependent claims can be combined with one another in a technologically meaningful manner and can define further refinements of the invention. In addition, the features specified in the claims are specified and explained in more detail in the description, with further preferred configurations of the invention being presented.

An arrangement is proposed comprising at least one axis of rotation and a first component arranged coaxially thereto and a centrifugal pendulum connected to the first component via a first connection which is form-fitting in relation to a circumferential direction and elastically prestressed in relation to the circumferential direction.

The first component is B. a torsional vibration damper or a clutch disc or an additional component that is non-rotatably connected to the torsional vibration damper or clutch disc (i.e. non-rotatable). Reference is made to the above statements on torsional vibration dampers and centrifugal pendulum-type pendulums.

Via the first connection, the centrifugal pendulum can be arranged on the first component in a simple manner that is free of play in relation to the circumferential direction. The first connection is designed to be form-fitting relative to the circumferential direction. Furthermore, the first connection is elastically prestressed relative to the circumferential direction, in particular by a spring element acting relative to the circumferential direction.

In particular, the first connection is formed by a spring element which is positively connected to the first component via at least one first connection and to the centrifugal pendulum via at least one second connection with respect to the circumferential direction.

The at least one second connection is arranged in particular on a carrier element or CPA flange of the centrifugal pendulum.

In particular, a plurality of first connections (ie contact surfaces between the spring element and the first component that act in a form-fitting manner with respect to the circumferential direction) are provided. In particular, the individual first connections are arranged at a distance from one another along the circumferential direction.

In particular, a plurality of second connections (that is to say contact surfaces between the spring element and the centrifugal pendulum which act in a form-fitting manner in relation to the circumferential direction) are provided. In particular, the individual second connections are arranged at a distance from one another along the circumferential direction.

Between the at least one first connection and the at least one second connection, the spring element has at least one spring area which, as a result of elastic deformation, enables the centrifugal pendulum pendulum to be arranged on the first component in a manner that is pretensioned relative to the circumferential direction.

In particular, the spring element is elastically deformable in an axial direction parallel to the axis of rotation, this deformation in the axial direction being coupled with a deformation of the spring element in the circumferential direction.

In particular, in a stress-free state of the spring element, the at least one first connection and the at least one second connection are spaced apart from one another along the axial direction, e.g. B. at a distance from each other, arranged. The first connection and the second connection are arranged spaced apart from one another by a first angular range along the circumferential direction. If the distance between the first connection and the second connection is changed, in particular reduced, the angle range between the first connection and the second connection changes towards a, in particular larger, second angle range. This change in the angular range is referred to below as displacement. This displacement enables the centrifugal pendulum to be arranged on the first component in a manner that is prestressed in relation to the circumferential direction.

In particular, the first component extends along the axis of rotation via a first face of the centrifugal pendulum through the centrifugal pendulum to a second face, with the spring element being arranged on the second face. In particular, the at least one first connection arranged between the spring element and the first component in the region of the second end face. In particular, the at least one second connection between the spring element and the centrifugal pendulum is arranged on the second end face.

In particular, the first component is a hub part with external teeth, the spring element forming the first connection via internal teeth with the hub part, the internal teeth being displaced relative to the external teeth along the circumferential direction by the braced spring element.

The hub part extends with the external toothing in particular coaxially and parallel to the axis of rotation.

In particular, the centrifugal pendulum is also arranged in a form-fitting manner on the external toothing of the hub part with respect to the circumferential direction via its own internal toothing. The connection of the toothings, which is regularly subject to play in relation to the circumferential direction, can now be prestressed without play in relation to the circumferential direction via the spring element.

In particular, the first component is a (at least partially cylindrical) sleeve, which extends with at least one extension along the axis of rotation through at least one first opening of the centrifugal pendulum and through at least one second opening of the spring element, thereby forming the first connection, with the braced arranged spring element, the second opening is arranged displaced relative to the first opening along the circumferential direction.

The connection between the extension and the openings, which is regularly subject to play in relation to the circumferential direction, can now be prestressed without play in relation to the circumferential direction via the spring element. The openings, which are initially aligned along the axis of rotation (e.g. to assemble the arrangement, i.e. to connect the centrifugal pendulum-type pendulum to the first component) along the axis of rotation, are displaced relative to one another along the circumferential direction by the spring element, so that the prestressed and backlash-free first connection is established is.

In particular, the spring element is supported on the first component in relation to an axial direction parallel to the axis of rotation and is thus arranged in a secured manner in relation to the axial direction between the centrifugal pendulum and the first component.

In particular, the at least one second connection is formed by a rivet connection. Alternatively, the second connection can also be realized by a welded connection or a screwed connection.

In particular, the at least one second connection is formed by a projection of the spring element that extends along the axis of rotation and engages in a third opening of the centrifugal pendulum.

In particular, the first component is non-rotatably connected to one of the following components or forms this component:

• • an output or input part of a torsional vibration damper;
• • a flange of a seesaw damper;
• • a hub of a clutch disc;
• • a hub of a rocker damper.

2. b) Bereitstellen des Fliehkraftpendels;

A method for assembling the arrangement described is also proposed, at least comprising the following steps:

1. a) providing the first component, possibly as part of a torsional vibration damper and/or a clutch disk;
2. b) providing the centrifugal pendulum;
3. c) arranging the centrifugal pendulum on the first component, in particular by pushing the centrifugal pendulum onto the first component along the axis of rotation; and
4. d) establishing the first connection.

In particular, step d) includes providing and arranging the spring element on the arrangement. The spring element can already be arranged on or connected to the centrifugal pendulum via the at least one second connection. In particular, in a stress-free state of the spring element, the at least one first connection and the at least one second connection are spaced apart from one another along the axial direction, e.g. B. at a distance from each other, arranged. The first connection and the second connection are arranged spaced apart from one another by a first angular range along the circumferential direction. If the distance between the first connection and the second connection is changed, in particular reduced, the angle range between the first connection and the second connection changes towards a, in particular larger, second angle range. This change in angular range is called displacement. This displacement allows the biased relative to the circumferential direction Arrangement of the centrifugal pendulum on the first component.

In the arrangement of the spring element, the spring element can initially be prestressed in relation to the axial direction and then relax in relation to the axial direction in the assembled state, thereby generating the pretension in relation to the circumferential direction. Alternatively, when the spring element is arranged, the spring element can initially be relaxed relative to the axial direction and only then be tensioned relative to the axial direction in the installed state, thereby generating the pretension relative to the circumferential direction.

Steps a) to d) take place in particular in the specified order.

The invention also relates to a drive train of a motor vehicle, at least comprising an internal combustion engine and a transmission, the arrangement described being arranged between the internal combustion engine or the drive shaft driven by it and the transmission or the transmission input shaft (referred to here as output shaft).

In particular, a primary side of the damping device of a torsional vibration damper can be connected to a clutch disk, which is arranged in a clampable manner between a pressure plate and a counterplate. If the pressure plate is shifted towards the counter plate, the clutch disc is clamped between them and a torque from the internal combustion engine can be introduced into the torsional vibration damper via the drive shaft and the clutch disc and passed on to the transmission via the output shaft.

The explanations regarding the arrangement can be transferred in particular to the method and the drive train and vice versa.

The use of indefinite articles (“a”, “an”, “an” and “an”), particularly in the claims and the description reflecting them, is to be understood as such and not as a numeral. Correspondingly introduced terms or components are to be understood in such a way that they are present at least once and in particular can also be present several times.

The arrangement 1 comprises an axis of rotation 2 and a first component 3 arranged coaxially thereto and a centrifugal pendulum 6 connected to the first component 3 via a first connection 5 which is form-fitting in relation to a circumferential direction 4 and is elastically prestressed in relation to the circumferential direction 4.

The first component 3 is here a sleeve-like element which is connected in a torque-proof manner to a flange of a torsional vibration damper 19 designed as a rocker damper 20 . The torsional vibration damper is connected to a clutch disc 21 .

The first connection 5 is formed by a spring element 7 which is positively connected to the first component 3 via a plurality of first connections 8 and to the centrifugal pendulum 6 via a plurality of second connections 9 with respect to the circumferential direction 4 . The second connections 9 are arranged on a carrier element or CPA flange of the centrifugal pendulum 6 .

The individual first connections 8 are arranged at a distance from one another along the circumferential direction 4 .

The individual second connections 9 are arranged at a distance from one another along the circumferential direction 4 .

The spring element 7 has an annular base body 24 in which the second openings 17 and thus the first connections 8 are arranged. Starting from the base body 24, spring areas 25 extend outwards along the radial direction 22, along the circumferential direction 4 towards the second connection 9 and thereby along the axial direction 10.

Between the at least one first connection 8 and the at least one second connection 9, the spring element 7 has a spring area 25 which, as a result of elastic deformation, enables the centrifugal pendulum 6 to be arranged on the first component 3 in a manner that is pretensioned relative to the circumferential direction 4.

The spring element 7 is elastically deformable in an axial direction 10 parallel to the axis of rotation 2, this deformation occurring in the axial direction device 10 is coupled with a deformation of the spring element 7 in the circumferential direction 4 .

In a stress-free state of the spring element 7, the at least one first connection 8 and the at least one second connection 9 are spaced apart from one another along the axial direction 10, e.g. B. at a distance from each other (see 5 , 12 until 14 ). The first connection 8 and the second connection 9 are arranged spaced apart from one another by a first angular range along the circumferential direction 4 . If the distance between the first connection 8 and the second connection 9 is changed, ie reduced, the angle range between the first connection 8 and the second connection 9 changes towards a larger second angle range. This change in angular range is called displacement 23 (see 13 ) designated. This displacement 23 enables the arrangement of the centrifugal pendulum 6 on the first component 3 in a prestressed manner in relation to the circumferential direction 4.

The first component 3 extends along the axis of rotation 2 via a first face 11 of the centrifugal pendulum 6 through the centrifugal pendulum 6 to a second face 12 , with the spring element 7 being arranged on the second face 12 . The at least one first connection 8 between the spring element 7 and the first component 3 is arranged in the area of the second end face 12 . The at least one second connection 9 between the spring element 7 and the centrifugal pendulum 6 is arranged on the second end face 12 .

The first component 3 is an at least partially cylindrical sleeve, which extends with an extension 15 along the axis of rotation 2 through a respective first opening 16 of the centrifugal pendulum pendulum 6 and through a respective second opening 17 of the spring element 7, thereby forming the first connection 8 , The second opening 17 being displaced relative to the first opening 16 along the circumferential direction 4 by the spring element 6 arranged braced relative to the circumferential direction 4 .

The connection between the extension 15 and the openings 16 , 17 , which is regularly subject to play in relation to the circumferential direction 4 , can now be prestressed without play in relation to the circumferential direction 4 via the spring element 7 . The openings 16, 17 (see Fig 4 ) along the circumferential direction 4 displaced relative to each other (see 5 ), so that the prestressed and backlash-free first connection 5 is established.

The spring element 7 is supported against an axial direction 10 parallel to the axis of rotation 2 on the first component 3 (here on shoulders 28 of the extensions 15) and is thus arranged secured against the axial direction 10 between the centrifugal pendulum 6 and the first component 3.

The second connections 9 are each formed by a riveted connection.

17 shows a second embodiment of an arrangement 1 in an exploded view, in a perspective view. 18 shows the arrangement 1 after 17 in a side view in section. 19 shows the spring element 7 of the arrangement 1 after 17 and 18 in a side view. 20 shows the spring element 7 after 19 in a view along the axis of rotation 2. 21 shows the spring element 7 after 19 and 20 in a perspective view. the 17 until 21 are described together below. On the remarks on the 1 until 16 is referenced.

The arrangement 1 comprises a torsional vibration damper 19 as in FIG 3 shown. The centrifugal pendulum 6 is connected to the torsional vibration damper 19 via a first component 3 designed as a hub part. The first component 3 is a hub part with an external toothing 13, with the spring element 7 forming the first connections 8 via an internal toothing 14 with the hub part, the internal toothing 14 being braced relative to the axial direction 10 in relation to the external toothing 13 along the circumferential direction 4 is arranged shifted.

The hub part extends coaxially with the external teeth 13 and parallel to the axis of rotation 2.

The centrifugal pendulum 6 is also positively arranged on the external toothing 13 of the hub part with respect to the circumferential direction 4 via its own internal toothing 14 . The connection of the toothings 13 , 14 , which is regularly subject to play in relation to the circumferential direction 4 , can now be prestressed without play in relation to the circumferential direction 4 via the spring element 7 .

The second connections 9 are each formed by a projection 18 of the spring element 7 that extends along the axis of rotation 2 and engages in a third opening 27 of the centrifugal pendulum 6 .

The spring element 7 has an annular base body 24 on an inner circumference surface has the internal teeth 14, which form the first connections 8 with the external teeth 13 of the hub part. Starting from the base body 24, spring areas 25 extend outwards along the radial direction 22, along the circumferential direction 4 along the axial direction 10 towards one projection 18, each with a third opening 27, forming the respective second connection 9.

The spring element 7 is supported on the hub part in relation to the axial direction 10 via a retaining ring 26 .

Here the spring element 7 is installed in a relaxed state and then prestressed along the axial direction 10 when the operational state is reached, so that the spring element 7 and the centrifugal pendulum pendulum 6 are displaced relative to one another in relation to the circumferential direction 4 and the teeth 13, 14 are arranged without play in relation to one another .
