Description
Technical Field
The invention relates to a centrifugal pendulum having a pendulum mass carrier, which is arranged so as to be rotatable about a rotational axis, and having pendulum masses, which are distributed over the circumference in the centrifugal force field of the rotating pendulum mass carrier and are received on the pendulum mass carrier so as to be pivotable along a predefined pendulum rail, wherein the pendulum masses are each formed by an intermediate part which is received in a recess of the pendulum mass carrier and two side parts which are arranged on both sides of the pendulum mass carrier, and wherein the pendulum bearings which adjust the pendulum rails are each formed by a running rail of the intermediate part which is diametrically opposite the pendulum mass carrier and a pendulum roller which rolls on the running rail.
Background
Centrifugal force pendulums are used for torsional vibration isolation in particular in drive trains of motor vehicles having internal combustion engines with rotational speed. For this purpose, the centrifugal pendulum has a pendulum mass carrier arranged so as to be rotatable about a rotational axis (for example, the rotational axis of a crankshaft of an internal combustion engine), on which pendulum masses distributed over the circumference and pivotable by means of pendulum bearings are predefined. In the event of a rotation of the pendulum mass carrier, the pendulum mass is accelerated radially outward and can be displaced on a predefined pendulum rail by means of the pendulum bearing, so that when torsional vibrations occur, it can be displaced to a smaller radius against the action of the centrifugal force and thus the rotational speed adaptively damps the torsional vibrations.
A typical arrangement of a pendulum mass on a pendulum mass carrier is known from DE 102009021355 a 1. Here, pendulum mass parts are arranged on both sides of the pendulum mass carrier, which are connected to form a pendulum mass by means of connecting means which pass through the pendulum mass carrier in the recess. The pendulum masses are mounted so as to be pivotable on the pendulum mass carrier by means of two pendulum bearings spaced apart in the circumferential direction, which are formed by running rails arranged axially next to one another in the pendulum mass part and in the pendulum mass carrier, wherein the hollow pendulum rollers running through the running rails roll on the running rails. Due to the axial deflection of the running rails of the pendulum bearing and the positioning of the pendulum rollers, for example by means of an annular flange, the axial installation space requirement is relatively high.
DE 102009042812 a1 discloses a centrifugal force pendulum integrated into a dual mass flywheel, which discloses, in particular, the following pendulum masses: the pendulum masses are mounted in recesses of the pendulum mass carrier, wherein the pendulum masses are supported by means of pendulum rollers which roll on running rails of the pendulum masses and of the pendulum mass carrier, which running rails are arranged one above the other in the radial direction, so that the pendulum masses are mounted in the mounting space of the pendulum mass carrier. In this case, the mass of the pendulum mass acts less on the torsional vibration damping if the axial extension of the pendulum mass is limited to the thickness of the pendulum mass carrier.
DE 102013214829 a1 shows a centrifugal force pendulum having a pendulum mass mounted in a recess of a pendulum mass carrier, which pendulum mass has pendulum bearings with running rails arranged radially one above the other. The pendulum mass is supported in the axial direction by means of a holding plate, which is arranged either on the pendulum mass carrier or on the pendulum mass. In the case of a holding plate which is fastened in particular to the pendulum mass, the holding plate does not contribute substantially to the mass of the pendulum mass.
Disclosure of Invention
The object of the invention is to advantageously develop a centrifugal force pendulum having: an intermediate piece arranged in the axial mounting space of the pendulum mass carrier; two side parts connected to the intermediate part and disposed on both sides of the pendulum mass carrier.
The object of the invention is, in particular, to provide a centrifugal pendulum having a narrow axial installation space for the pendulum mass and a high mass fraction. The object of the invention is, in particular, to provide a centrifugal pendulum having a stably guided pendulum mass. The object of the invention is, in particular, to provide a centrifugal pendulum which is robust and stable over time.
The proposed centrifugal force pendulum is used for the torsional vibration damping for adapting the rotational speed, in particular in a drive train having an internal combustion engine with a rotational speed. The centrifugal force pendulum can be coordinated with one or more vibration stages of the internal combustion engine. The centrifugal force pendulum can be integrated as a separate device into the drive train or into another device (for example a torsional vibration damper such as a dual mass flywheel), into a single mass flywheel, a friction clutch, a dual clutch, a clutch disk, a hydrodynamic torque converter or the like. The centrifugal force pendulum comprises a pendulum mass carrier arranged so as to be rotatable about a rotational axis. The pendulum masses are distributed over the circumference in the centrifugal force field of the rotating pendulum mass carrier, on which the pendulum masses are received so as to be pivotable along a predefined pendulum path. The pendulum masses are each formed by an intermediate part which is received in a recess of the pendulum mass carrier and two side parts which are arranged on both sides of the pendulum mass carrier. The pendulum bearings each adjust a pendulum mass and each comprise a running rail of the intermediate part, which runs opposite to the pendulum mass carrier in the radial direction, and a pendulum roller which rolls on the running rail. The recess can be open or closed at the radial outside.
In order to be able to receive the pendulum masses on the pendulum mass carrier in a pivotable manner, in a preferred manner, two pendulum bearings spaced apart in the circumferential direction are provided per pendulum mass, so that a pendulum path corresponding to the pendulum masses of the pendulum suspended in two lines is produced. The pendulum rail can be designed in accordance with pendulum embodiments having cycloids arranged parallel or trapezoidally or in a free form. The rotation of the pendulum mass during the pendulum movement can be set. The running rail of the pendulum bearing is designed accordingly for adjusting the pendulum rail.
A centrifugal pendulum which is particularly narrowly produced, i.e. provided with a small axial installation space, can be provided according to the concept of the invention in that the sum of the thicknesses of the side parts is equal to or less than 2 times the thickness of the pendulum mass carrier, preferably less than 1.6 times the thickness of the pendulum mass carrier, and in a particularly advantageous manner less than 1.2 times the thickness of the pendulum mass carrier. This means that in the extreme case the side parts together are only insignificantly thicker than the thickness of the intermediate piece or pendulum mass carrier. Furthermore, it has proven to be advantageous if the mass of the intermediate piece has a proportion of at least 20%, preferably at least 35%, particularly preferably at least 50% and less than 80%, of the total mass of the pendulum mass. In this case, the mass is concentrated in the intermediate piece, so that a stable pendulum movement is produced and the overall mass of the pendulum mass and thus the efficiency of the centrifugal pendulum is also increased by the contribution of the relatively thin side parts. Furthermore, it has proven to be advantageous if the side part intersects at least a part of the hollow of the pendulum mass carrier for receiving the intermediate part in the radial direction. In this way, the pendulum mass is stabilized with respect to the pendulum mass holder and is received in a loss-proof manner, for example, in a pendulum-proof manner (taugelschwingung) and the like. The side parts and the intermediate part are connected to each other (e.g. riveted), by means of a tongue which passes through an opening in the intermediate part and is turned over, snapped on, crimped or the like. Alternatively or additionally, the side parts can be formed in one piece and U-shaped in cross section, wherein the side parts are connected by means of webs or the like in such a way that they surround the pendulum mass carrier radially on the outside. For this purpose, the side parts can be stamped from sheet metal and turned over in a U-shaped manner.
According to an advantageous development of the proposed centrifugal force pendulum or as a separate embodiment of the centrifugal force pendulum, the contact surfaces of the components of the centrifugal force pendulum with the further components can be hardened, in particular the contact surfaces between the side parts and the pendulum mass carrier, the running rail and/or the pendulum roller. In this case, the component having at least one hardened contact surface of this type can be formed in multiple parts from a hardened structural element and a soft structural element. For example, inserts with hardened running rails can be provided on the intermediate piece and/or on the pendulum mass carrier.
Alternatively or additionally, the side parts can be constructed from different materials, for example, having different thicknesses. For example, the intermediate part can have a greater thickness than the side parts. For this purpose, in the case of soft materials, the regions of high mechanical stress (e.g. running rails) are designed as inserts made of more durable materials (e.g. hardened materials). Furthermore, the highly loaded regions can be partially hardened, in particular case hardened, and/or coated, for example, with a CLD coating, PVD coating or the like.
Means for reducing friction and/or for protecting the areas that touch one another can be provided between the side parts and the pendulum mass carrier. For example, axially projecting impressions and/or plastic elements (e.g., plastic clips) or the like can be provided on the side parts and/or on the pendulum mass carrier. In an advantageous manner, a hardened metal sheet can be arranged between the side parts and the pendulum mass carrier. Such a metal sheet can have a smaller thickness than the side parts, in particular a much smaller thickness, for example below 1 mm.
Since the hardening of the side parts which move past the pendulum mass carrier can be complicated in terms of production technology, it is proposed to separate the functions and to arrange a further, separate and hardened metal plate (preferably having only a very small axial thickness) between the components which are to be run against (anlaufend). Such spacer plates essentially only have the function of protecting the side parts, which can be configured in a soft manner here, from running axially against the pendulum support. Any warping of this hardened and preferably very thin spacer plate can be tolerated or pressed by the plate by being inserted into the pendulum mass composite structure (plattgerdruckt). Due to the separate construction of the side parts, which are constructed relatively thick compared to the thin hardened metal sheet, more structural freedom and/or cost advantages in the production and assembly process can be achieved.
Preferably, the hardened intermediate plate is mounted on the side part, so that at the same time the effective mass of the pendulum is increased, in individual cases it can also be provided that the hardened metal plate is mounted on the pendulum mass carrier, for example for assembly reasons. The proposed hardened plate can be implemented with different plate thicknesses depending on the embodiment. They can be constructed in a smaller area relative to the area of the side pieces. The metal plate can be flat or have an axial contour, for example with a stamp, projecting elements or the like and/or a wave-shaped configuration, so that the contact surface with respect to the pendulum mass carrier or the side part is reduced as a function of the arrangement. The metal plate can be connected to the respective component (side part or pendulum mass carrier) by riveting, clamping, crimping, latching, gluing and/or in another way. Furthermore, additional spacer elements can be provided on the hardened metal sheet in one piece or in multiple pieces. A metal plate, such as a spacer plate, at least partially covers (and in a preferred manner completely covers) the pendulum rollers of the pendulum bearing.
According to an advantageous embodiment, the proposed centrifugal force pendulum comprises only (or in combination with further design features) a pendulum mass whose center of gravity is arranged radially outside, with respect to the axis of rotation, a line between the radially innermost outer peripheries of the two pendulum rollers spaced apart in the circumferential direction, preferably radially outside, a line between the radially outermost outer peripheries of the two pendulum rollers spaced apart in the circumferential direction, in particular for avoiding tilting movements of the pendulum mass and for avoiding friction relative to the relatively moving component (pendulum mass carrier) which is generated thereby on the circumferential side. This criterion applies at least to the position of the pendulum mass preferably at the zero position (e.g. the central position of the pendulum mass along its pendulum path, i.e. if arranged at the maximum radius).
The side parts can be displaced radially outward, the intermediate part can be widened radially outward relative to the center of gravity, and/or at least one additional mass (i.e. connected separately to the intermediate part or the side parts or designed in one piece) can be arranged on the intermediate part and/or on at least one of the side parts for displacing the center of gravity of the pendulum mass.
Alternatively or additionally, the intermediate piece can extend radially outward on the pendulum mass carrier and overlap the pendulum mass carrier in the circumferential direction, for example, in order to increase the mass or the moment of inertia of the pendulum mass. In this case, the circumferentially adjacent intermediate pieces can be elastically coupled to one another radially outside the pendulum mass carrier by means of spring elements acting in the circumferential direction. The intermediate part can be divided in two parts into parts arranged inside and outside the pendulum mass carrier and connected to one another. Advantageously, the intermediate piece is constructed in one piece. The side parts connected to the intermediate piece can thereby be of relatively small design and fix the intermediate piece and the pendulum rollers in the axial direction. For this purpose, the side parts at least partially cover the pendulum roller and at least partially overlap the pendulum mass carrier. In the case of a separate construction of the intermediate piece as radially inner and radially outer parts, the side part can connect these two parts to one another.

Detailed Description
Fig. 1 and 2 show a centrifugal force pendulum 100, which can be arranged in a twisting manner about a rotational axis d, in a partial view (fig. 1) and in an upper partial sectional view along the sectional line a-a (fig. 2). The centrifugal force pendulum 100 comprises a pendulum mass carrier 101, on which the pendulum masses are pivotably received by means of two pendulum bearings 103 spaced apart in the circumferential direction, of which only one of the pendulum masses 102 arranged distributed over the circumference is shown, and a pendulum mass 102. The pendulum mass 102 is formed by an intermediate part 104 and two side parts 105 arranged laterally to the pendulum mass carrier 101, which are riveted to one another here, for example, by means of rivets 110. In order to further reduce the installation space, the rivets 110 can be arranged sunk in the side pieces 105 and the intermediate piece 104. For this purpose, corresponding countersunk portions can be provided in the side parts and the intermediate part. In fig. 1, the front side part is removed for the sake of clarity.
The pendulum bearing 103 is formed by running rails 106, 107 arranged in the intermediate piece 104 and in the pendulum mass carrier 101, and by pendulum rollers 108 rolling on said running rails. The pendulum mass carrier 101 has a recess 109, in which the intermediate piece 104 is received, so that the pendulum bearing 103 between the pendulum mass 102 and the pendulum mass carrier 101 is formed at the same height in the axial direction. In the exemplary embodiment shown, the recess 109 is closed radially on the outside, but can be open radially on the outside.
The side part 105 overlaps the pendulum mass carrier 101 and the pendulum roller 108 at least in part, so that the pendulum mass 102 is supported in the axial direction on the pendulum mass carrier 101 and the pendulum roller 108 is received in the pendulum bearing 103 in a loss-proof manner.
The pendulum mass carrier 101 and the intermediate piece 104 have substantially the same thickness F. In a preferred manner, the side members 105 have the same thickness D1、D2. In order to optimize the design of the pendulum mass 102 with respect to its axial extent and its mass, a specific thickness and mass relationship is provided between the intermediate piece 104 and the side pieces 105. Preferably, the thickness D is set1、D2So that they do not exceed 2 times, preferably 1.6 times and particularly preferably 1.2 times the thickness F of the pendulum mass carrier 101 or the intermediate piece 104. In particular, due to the arrangement of the center of gravity of the side parts 105 relative to the center of gravity of the intermediate part 104, it can be particularly advantageous if the side parts are correspondingly narrowly formed and the mass relationship is advantageously shifted to the middle part 104. It can therefore be advantageous to design the proportion of the intermediate piece 104 in the total mass to be between 20% and 80%, preferably between 35% and 80%, and particularly preferably between 50% and 80%.
Fig. 3 and 4 show the centrifugal force pendulum 200 in a 3D partial view, wherein the side part 205 of the pendulum mass 202 facing the observer is omitted in the otherwise identical illustration in fig. 4. In contrast to the centrifugal pendulum 100 of fig. 1 and 2, a hardened metal plate 211 is arranged between the pendulum mass carrier 201 and the side part 205, said metal plate serving as a spacer plate relative to the pendulum mass carrier 201.
The metal plate 211 is of narrow design relative to the thickness of the side parts 205 and is riveted in the illustrated exemplary embodiment between the intermediate part 204 and one of the respective side parts 205 by means of a rivet 210. In a further embodiment of the centrifugal force pendulum 200, the metal plate 211 can be connected to the pendulum mass carrier 201. The metal plate 211 forms a preferably elastic contact between the side part 205 and the pendulum mass carrier 201, so that the side part 205 can be of soft design and therefore can be produced inexpensively and simply. The metal plate 211 can be profiled in the axial direction and only occupies a part of the surface of the side part 205. In the exemplary embodiment shown, the metal plate 211 comprises two radially extending tongues 212 which form an abutting contact with the pendulum mass carrier 201.
Fig. 5 shows a modified metal plate 211a with respect to the metal plate 211 of fig. 3 and 4, which has three radially extending tongues 212 a. In addition, the central tongue 212a comprises an axially widened indentation 213a (e.g., an axial profile) in order to further reduce the contact surface with the pendulum mass carrier.
Fig. 6 shows a partial view of a centrifugal force pendulum 200a, which is similar to the centrifugal force pendulum 200 of fig. 3 and 4 with the front disk removed and is equipped with the metal plate 211a of fig. 5. In accordance with the centrifugal force pendulum 200, the metal plates 211a are riveted between the respective side part 205a and the intermediate part 204a by means of rivets 210 a. The abutting contact with the pendulum mass carrier is preferably realized on the tongue 212 a.
Fig. 7 and 8 show a centrifugal force pendulum 300 arranged about a rotational axis d in a view (fig. 7) and in a section (fig. 8) with the upper part along the sectional line B-B of fig. 7, in a modification of the centrifugal force pendulums 100, 200a of fig. 1 to 4 and 6. On the pendulum mass carrier 301, an intermediate piece 304 is received by means of the pendulum bearing 303 in an outwardly open recess 309, said intermediate piece extending radially outward into the opening of the recess 309. Furthermore, the side parts 305 connected to the intermediate part 304, which are arranged on both sides of the pendulum mass carrier 301 and form the pendulum mass 302 in accordance with the intermediate part 304, are designed to be minimal, so that they are sufficient to support the pendulum mass 302 relative to the pendulum mass carrier 301 and to hold the pendulum roller 308 of the pendulum bearing 306 in its position against the ground.
Due to the respective mass distributions of the side parts 305 and the intermediate part 304 of the pendulum mass 302, the center of gravity S is located radially outside of an imaginary line between the pendulum rollers 308 of the pendulum bearing 303, with the maximum radius in the illustrated zero position of the pendulum mass 302. In a preferred embodiment, the center of gravity S is arranged outside a line X-X which extends between the radially innermost outer peripheries of the two circumferentially spaced pendulum rollers 308 of the pendulum mass 302 of the pendulum bearing 303. In a further improved embodiment, in the zero position of the pendulum mass 302, the center of gravity S is arranged radially outside of a line Y-Y extending between the radially outermost outer peripheries of the pendulum rollers 308.
Fig. 9 shows in section the upper part of a centrifugal force pendulum 300a with a pendulum mass carrier 301a and a pendulum mass 302, arranged about a rotational axis d. In contrast to the centrifugal pendulum 300, the intermediate part 304a has additional masses 313a arranged on both sides and apart from the side parts 305a, which are riveted to the intermediate part 304a in the exemplary embodiment shown, in order to displace the center of gravity of the pendulum mass 302a radially outward. In further embodiments, the additional mass can be formed, for example, in one piece from the intermediate part and can be folded over (e.g., folded over), or the intermediate part can be provided thickened in a material-modified manner.
Fig. 10 and 11 show a centrifugal force pendulum 400 arranged about a rotational axis d in a view (fig. 10) and an upper part in a section (fig. 11), which has a pendulum mass carrier 401 and pendulum masses 402 arranged distributed over the circumference and pivotably received on the pendulum mass carrier 401 by means of pendulum bearings 403. The intermediate piece 404 received in the radially outwardly open recess 409 of the pendulum mass carrier 401 has a first part 414 which is arranged in the recess 409 and a second part 415 which expands radially and on both sides in the peripheral direction on the outer periphery of the pendulum mass carrier 401. The side part 405 supports the pendulum mass 402 relative to the pendulum mass carrier 401 and forms a loss prevention device for the pendulum roller 408. Furthermore, the side part 405 connects the parts 414, 415 to each other in the case they are constructed separately. In a preferred manner, the intermediate piece 404 is constructed in one piece.
The intermediate piece 404 and thus the pendulum mass 402 are coupled radially to the outside at a region 416 of the intermediate piece 404 that is expanded in the peripheral direction, for example, by means of a spring element 417 that is elastic in the peripheral direction, in order to synchronize them.
Fig. 12 and 13 show in partial views an upper part of a centrifugal force pendulum 500, arranged about a rotational axis d, having a pendulum mass carrier 501 and a pendulum mass 502. Unlike the centrifugal force pendulum 400 of fig. 10 and 11, the intermediate piece 504 is embodied in such a way that it is divided into a part 514 arranged in the recess 509 and a part 515 arranged outside the outer circumference of the pendulum mass carrier 501 and extending in both circumferential directions. The side part 505 expands radially on the outer circumference of the pendulum mass 502 and connects the two parts 514, 515 to one another, for example by means of rivets 518, 519. In the exemplary embodiment shown, the spring element 517 is arranged between the radially expanded regions 516 of the part 515, but can also be received in a supported manner on the side part 505 in the circumferential direction.
