Description
Technical Field
The invention relates to a centrifugal pendulum having a pendulum flange which is arranged so as to be rotatable about a rotational axis and having pendulum mass units which are distributed in the circumferential direction on the pendulum flange and which, in the centrifugal force field of the pendulum flange which is rotatable about the rotational axis, are each pivoted along a predefined pivot path by means of two pivot supports which are spaced apart in the circumferential direction, the pendulum mass units comprising side parts which are arranged axially opposite one another on both sides of the pendulum flange and an intermediate part which engages through a recess of the pendulum flange, wherein an end stop for limiting the pivot angle of the pendulum mass unit relative to the pendulum flange is provided between the pendulum flange and the pendulum mass unit.
Background
Centrifugal pendulums are used for torsional vibration isolation in particular in the drive train of motor vehicles having a torsionally vibrating internal combustion engine. In this case, pendulum mass units distributed over the circumference are provided on a pendulum flange arranged to be rotatable, for example driven by an internal combustion engine, which pendulum mass units are suspended in the centrifugal force field of the rotatable pendulum flange so as to be displaceable along a predefined pendulum path on the pendulum flange and which form a torsional vibration damper adapted to the rotational speed by displacement along a pendulum path of different radii as a function of the torsional vibrations introduced.
A centrifugal pendulum of this type is known, for example, from DE 102016205420 a1, in which pendulum mass units are arranged distributed over the circumference, which are accommodated so as to be pivotable along a predefined pivot path by means of a pivot bearing along the predefined pivot path. The axially opposite side parts arranged on both sides of the pendulum flange are connected to each other by means of an intermediate part which moves in a recess of the pendulum flange. The side parts and the intermediate part form the individual pendulum mass units. The oscillating bearing is arranged between the intermediate part and the oscillating flange, wherein the guide rails of the intermediate part and the oscillating flange are arranged radially one above the other and each have an oscillating roller that rolls on the guide rails. In order to limit the pivot angle of the pendulum mass part relative to the pendulum flange and to prevent the pendulum roller from striking the pendulum flange too sharply or to prevent the pendulum roller from tilting, a damping element made of plastic is arranged on the intermediate part, which forms a stop relative to the circumferential wall of the recess in order to establish an end stop of the pendulum mass unit relative to the pendulum flange. The damping element is snapped onto the complex stamped contour of the intermediate part.
Disclosure of Invention
The object of the invention is to improve a centrifugal pendulum of this type. In particular, the object of the invention is to provide a centrifugal pendulum which can be produced in a simple manner and has a pendulum mass unit with a large mass.
The object is achieved by a centrifugal pendulum having a pendulum flange arranged rotatably about a rotational axis and pendulum mass units distributed circumferentially at the pendulum flange, which can be pivoted in the centrifugal force field of the pendulum flange rotating about the rotational axis by means of two circumferentially spaced apart pivot supports along a predefined pivot path, each pendulum mass unit comprising side parts arranged axially opposite one another on both sides of the pendulum flange and an intermediate part engaging through a recess of the pendulum flange, wherein an end stop for limiting the pivot angle of the pendulum mass unit relative to the pendulum flange is provided between the pendulum flange and the pendulum mass unit, wherein the end stop is accommodated as an elastic damping element at the pendulum flange.
The proposed centrifugal pendulum is used as a rotational speed adaptive damper, in particular in the drive train of a motor vehicle having a rotational speed driven internal combustion engine. The centrifugal pendulum here comprises a pendulum flange arranged so as to be rotatable about a rotational axis, for example a pendulum flange which is directly connected to the crankshaft or, in the case of torsional vibration dampers, for example dual-mass flywheels, preferably on the output side. Pendulum mass units are accommodated in the pendulum flange in a circumferentially distributed manner. The pendulum mass unit arrangement comprises two axially opposite side parts and an intermediate part arranged on both sides of the pendulum flange. The side parts and the intermediate part are fixedly connected to each other, for example riveted to each other. The intermediate part engages through a recess, which is dimensioned in such a way that the pendulum mass unit can be pivoted along a predefined pivot path in the centrifugal force field of a pendulum flange that can be pivoted about a pivot axis. The wobble track is set by two circumferentially spaced wobble supports. The pendulum supports are formed in each case by rails which are of complementary design to one another on the pendulum mass unit and on the pendulum flange and on which the pendulum rollers roll.
In order to avoid the swing roller from violently impacting on the swing flange and the swing roller from tilting, a stop piece for limiting the swing angle of the swing mass unit relative to the swing flange is arranged between the swing flange and the swing mass unit. According to the inventive idea, the stop element is accommodated as an elastic damping element on the pendulum flange. The pendulum mass unit can thus be constructed in a simple manner, i.e., can be produced by means of a simple stamping geometry. The installation space for the damping element on the pendulum mass unit can be saved, so that the pendulum mass unit can fill up the saved installation space and can thus be set to a correspondingly higher mass of the pendulum mass unit, so that the pivotable centrifugal pendulum mass is increased without the need of increasing the overall installation space of the centrifugal pendulum.
The damping element may be received at a recess of the pendulum flange for the intermediate part. For this purpose, recesses can be provided in the wall. The damping element can be locked with the pendulum flange, snapped into it or received in a similar manner. In an alternative embodiment, an opening, which is formed separately from the recess and in which the damping element is introduced, can be provided on the pendulum flange. In accordance with an embodiment of the damping element, end stops of the side parts arranged on both sides of the pendulum flange or end stops of the intermediate part can be arranged on the damping element.
The side parts and the intermediate part are preferably made entirely of steel, so that a correspondingly high mass of the pendulum mass part is achieved. The side and/or intermediate parts are preferably produced by means of a sheet metal stamping method and can be shaped accordingly if necessary. For example, projections can be pressed out of the side parts, which reduce the contact surface of the side parts on the flange. Alternatively or additionally, corresponding elements that reduce the contact surface, for example molded projections or introduced plastic spacers, can be provided on the pendulum flange. The pendulum flange is preferably produced from sheet metal by means of a stamping/forming process. In order to simultaneously load the spring device on the output side in the case of a centrifugal pendulum in a torsional vibration damper, the pendulum flange can have arms which widen radially outward and which engage, for example, between circumferentially spaced end sides of a helical compression spring, for example an arc spring.
The damping element can be made of plastic and/or of a steel spring element. The damping element can have a corresponding holder, such as a lateral cutout, a hook or the like, introduced into the pendulum flange or mounted thereon in a form-fitting manner.
According to an advantageous embodiment of the proposed centrifugal pendulum, the pendulum support can be configured between the side part and the pendulum flange. In this case, a predefined guide rail of the pivoting path of the pivoting mass unit is provided in the side part and in the pivot flange, on which guide rail the pivoting rollers roll. The guide rails are formed, for example, on recesses of the side parts and of the pendulum flange, wherein the pendulum rollers engage through the recesses and the pendulum mass unit is supported radially on the pendulum flange under centrifugal force.
In order to avoid impact noise of the pendulum mass unit which falls radially inward due to gravity in the event of an insufficient centrifugal force, a damping element can be provided on the intermediate part, so that the pendulum mass unit is radially supported radially inward in the event of an insufficient centrifugal force. The damping element can be suspended as a radial spring clip in the intermediate part and can be made of plastic or spring sheet, for example. In an alternative embodiment, a damping element can be provided on the pendulum flange in order to support the pendulum mass unit radially inward in the event of an insufficient centrifugal force. Advantageously, the end stop and the damping element can be constructed in one piece. For example, the damping element can be operatively arranged relative to a circumferential end of the intermediate part, wherein the damping element extends circumferentially towards the radially inner part and in turn radially supports the intermediate part. In this case, the radially inner contour of the intermediate part and the radially outer contour of the pendulum flange can be designed such that the pendulum movement of the pendulum mass unit within the end stop takes place without interference and the radial path of the pendulum mass unit up to the spring stop on the damping element is minimal in the event of a lack of centrifugal force.
According to an alternative embodiment of the proposed centrifugal pendulum, the pendulum support can be constructed between the intermediate part and the pendulum flange. Here, the guide rails arranged radially one above the other at the intermediate part and at the recess are arranged axially in a row, between which the swivel rollers roll. In this case, the pendulum mass unit is supported against the centrifugal force in a radial direction on a straight line between the guide rail and the pendulum roller.

The invention is explained in detail on the basis of the exemplary embodiments shown in fig. 1 and 2. It shows that:
FIG. 1 shows a schematic partial view of a centrifugal pendulum, an
Fig. 2 shows a schematic partial view of a centrifugal force pendulum modified with respect to the centrifugal force pendulum of fig. 1.
Detailed Description
Fig. 1 shows a partial view of a centrifugal pendulum 1 arranged rotatably about a rotational axis d, having four pendulum mass units 3 arranged distributed over the circumference, which are received on a pendulum flange 2 by means of a pendulum support 4 in a manner pivotable in the centrifugal force field of the pendulum flange 2 rotatable about the rotational axis d along a pendulum path predefined by the pendulum support 4.
The pendulum mass unit 3 is formed by side parts 5 arranged on both sides of the pendulum flange 2, wherein the side parts arranged on the front side of the central upper part are omitted for clarity. The side parts 5 are connected to one another by means of an intermediate part 6, for example riveted to one another by means of rivets 7. The intermediate part 6 is accommodated in a recess 8 of the pendulum flange 2, the outer dimensions of which match the intermediate part 6 and its required travel path within the pendulum angle of the pendulum mass unit 3.
In the illustrated embodiment, the pivot bearing 4 is formed between the side part 5 and the pivot flange 2. For this purpose, openings 9, 10 are introduced into the side part 5 and into the pendulum flange 2, at which openings guide rails 11, 12 are machined. The oscillating roller 13 rolls on the guide rails 11, 12 axially across the openings 9, 10.
In order to limit the pivot angle of the pendulum mass unit 3 before the pivot roller 13 strikes the wall of the circumferential side of the openings 9, 10, end stops 14 are provided in both displacement directions of the pendulum mass unit 3. In order to save installation space and to simplify the design of the intermediate part 6, the end stop 14 is designed as a damping element 15, which is mounted on the pendulum flange 2. In the exemplary embodiment shown, the damping element 15 is received in a form-fitting manner, for example, is snapped into a wall 16 of the circumferential side of the recess 8.
In order to protect the intermediate part 6 on the pendulum flange from violent impacts against the radially inner wall 17 of the recess 8 without sufficient centrifugal force and in the event of a radially inner displacement associated with the pivoting force, a damping element 18 is arranged on the intermediate part 6, which is suspended as a spring clip 19 in the intermediate part 6. The contour of the wall 17 is designed to follow the path of movement of the intermediate part 6 over the entire pivot angle, so that a constant small distance is formed between the spring clip 19 and the walls 16, 17 of the recess 8 over the entire pivot angle of the pendulum mass unit 3.
The illustrated centrifugal pendulum 1 is used for a torsional vibration damper, for example a dual-mass flywheel. The pendulum flange is additionally used for loading the spring device of the torsional vibration damper on the output side and for this purpose has radially widened arms 20 which engage radially inwardly between circumferentially adjacent end sides of circumferentially distributed helical compression springs, for example arc springs, and load the helical compression springs in the circumferential direction.
Fig. 2 shows a detail view of an intermediate part 6a schematically illustrating a part of the centrifugal force pendulum 1a modified from the centrifugal force pendulum of fig. 1. The variation of the centrifugal force pendulum 1a is similar to the centrifugal force pendulum device of document DE 102016205420 a1, the contents of which are all included in the present patent application. Instead of the intermediate piece 116, an intermediate piece 6a of the centrifugal force pendulum 1a is provided. In contrast to the intermediate part 116 with the damping element 110, the intermediate part 6a is made entirely of metal and has a high mass due to the additional material region 21a, so that the pivotable mass of the intermediate part 6a increases by, for example, approximately 15%.
The centrifugal force pendulum 1a has a pendulum support 4a, which is formed between the pendulum flange 2a and the intermediate part 6 a. The guide rails 11a of the pendulum flange 2a and the guide rails 12a of the intermediate part 6a are arranged radially above one another. The swing roller 13a rolls between the guide rails 11a and 12 a. An end stop 14a is provided in the swing flange 2 a. The end stop 14a is designed as a damping element 15a which is inserted into the recess 8a accommodating the intermediate part 6a and is connected to the pendulum flange 2 a. The damping element 15a is arranged around the corners of the wall portions 16a, 17a of the recess 8a and, in addition to the end stop of the intermediate part 6a, also serves as a damping element 18a of the intermediate part 6a in the event of insufficient centrifugal force.
The intermediate part 6a is connected to the side parts 5a arranged on both sides of the pendulum flange 2a by means of rivets 7a to form the pendulum mass unit 3 a.
