Definitions
- the invention relates to a torsional vibration damper in particular for a drive train of a motor vehicle with a rotatable about an axis of rotation flange and a plurality of circumferentially distributed, arranged on both sides of the flange and relative to these relatively displaceable absorber masses, wherein each two axially opposite, arranged on each side of the flange Tilgermassen by means of the flange axially spaced spacer elements are connected to each other to a Tilgermassenzip, the absorber masses of Tilgermassenschreibs each have two circumferentially spaced first raceways for each rolling element, which roll on to these complementary second raceways of the flange.
- Generic torsional vibration damper are known as centrifugal pendulum or speed-adaptive absorber.
- this flange parts are provided, for example, rotationally connected to the crankshaft or an output part of a torsional vibration damper and distributed over the circumference, relative to the flange relatively limited displaceable absorber masses have, depending on the speed of the flange and thus centrifugally dependent pendulum radially and circumferentially oscillate around a neutral point and pay off with appropriate adjustment of the resonance conditions such as pendulum length, mass, swing angle and the like torsional vibrations in the drive train.
- a torsional vibration damper in conjunction with a torsional vibration damper in the form of a dual mass flywheel in which absorber masses are arranged on both sides of a flange part, wherein the absorber masses lying axially opposite are each connected to a damping mass pair.
- the Tilgermassenrune are relative to the flange by means of two spaced-apart in the circumferential direction spaced rolling elements, each roll in a raceway of the flange and in raceways of the absorber masses, limited displaceable added to the flange.
- the type and shape of the raceways specify the pendulum length and the swing angle.
- the object of the invention is therefore to further develop generic torsional vibration damper such that at reduced production costs contact between the absorber masses and flange are largely excluded.
- a torsional vibration damper in particular for a drive train of a motor vehicle with a flange rotatable about a rotation axis and a plurality of circumferentially distributed, disposed on both sides of the flange and relative to these relatively displaceable absorber masses, each two axially opposite, on one side of the Flange part arranged absorber masses are connected to each other by means of the flange axially spaced spacer elements to each Tilgermassenzip, the absorber masses of Tilgermassencrus each have two circumferentially spaced first raceways for each rolling element, which roll on to these complementary second raceways of the flange, and contact surfaces between rolling elements and raceways of a respective absorber mass pair are arranged radially within a center of gravity of the absorber mass pair.
- the raceways are displaced radially inward on the flange part and on the absorber masses.
- the structure of the proposed torsional vibration damper becomes simple and inexpensive to manufacture while improving vibration and noise performance.
- this corresponds to a conventional torsional vibration damper with radially inside or at the same height as the center of gravity absorber arranged raceways a pendulum with unstable or indifferentem balance, while the proposed torsional vibration damper resembles a pendulum in a stable equilibrium, the pendulum masses such as absorber masses not against the weight force commute against the centrifugal force.
- the tracks of the absorber masses are further displaced inwards, for example, arranged in the inner third of the radial extent of the absorber masses.
- the center of gravity of the absorber masses may each be provided radially outside a first line connecting the two contact surfaces between the rolling elements and the first raceways.
- the center of gravity of the absorber masses can each be provided radially outside a second line connecting the two contact surfaces between the rolling elements and the second raceways.
- the center of gravity is arranged outside of a recording of the absorber masses on the flange even if, for example, in the stationary state of the flange without centrifugal force, the absorber masses located radially above the pivot point of the flange due to weight radially outwardly supported on the rolling elements.
- a renewed acceleration of the flange occurs immediately a stabilization of the absorber masses without passage of an indifferent or unstable position of these absorber masses by the resulting centrifugal force, so that even at very low speeds, a stop the absorber masses can be avoided on the flange.
- the absorber masses are designed so that the center of gravity is provided in the circumferential direction between the circumferentially spaced raceways of a Tilgermassencrus. Ideally, the absorber masses are formed symmetrically to a radial section through the center of gravity.
- the rolling elements are secured against loss in the recesses for the formation of the raceways of the absorber masses by providing captive securing devices for these on the sides of the absorber masses facing away from the flange part.
- These may be formed by cover plates, which are provided with opposite the opening surfaces of the raceways narrowed opening surfaces or have no openings.
- the cover plates may be formed from sheet metal, so that the Tilgermassenforme are formed exclusively of metal.
- Particularly advantageous may be a material deformation, for example, as a molded nose in the outer surface of the absorber mass, which secure the rolling elements axially before emigrating. In this way, the number of parts can be further reduced, so that a self-stabilized and provided with a captive Tilgermassencovercover from only six parts - two absorber masses, two rolling elements and two spacers can be formed.
- a torsional vibration damper with two mutually counteracting the effect of circumferentially effective energy storage relatively rotatable damper parts, which is formed with the proposed torsional vibration, wherein one of the two damper parts, an input part or an output part of the torsional vibration damper forms the flange of the torsional vibration damper.
- the torsional vibration damper may for example be a dual-mass flywheel, wherein the flange preferably from the formed with the secondary flywheel damper part for acting on the energy storage as bow springs is formed.
- the flange part can have radially outwardly extended arms, which act on the output side of the end faces of the bow springs in the circumferential direction.
- FIG. 2 is a view of the torsional vibration damper of FIG. 1;
- FIG. 3 is an exploded view of the torsional vibration damper of FIGS. 1 and 2;
- Figure 4 is a partial view of the torsional vibration damper according to the invention.
- FIG. 1 shows the upper half of a torque transmission device 1 arranged about an axis of rotation 2, which is arranged in a drive train of a motor vehicle between an internal combustion engine (not shown) and a transmission (also not shown).
- the torque transmission device 1 comprises a dual-mass flywheel 3, on the secondary flywheel 4 of the torsional vibration damper 5 is arranged in function of a centrifugal pendulum.
- the torsional vibration damper 5 is formed according to the prior art and is to explain the typical structure and function of such torsional vibration damper and their example, use in a drive train of a motor vehicle of the invention shown in Figure 5 in partial view torsional vibration damper 5a closer.
- the secondary flywheel 4 also receives a friction clutch 6, which is designed as a three-disc clutch.
- the friction clutch 6 builds radially smaller at a high transmittable torque compared with a two-disc clutch, so that the torsional vibration damper 5 can be arranged axially adjacent to the energy accumulators 7 of the dual-mass flywheel 3 approximately at the same radial height.
- torsional vibration dampers can be arranged radially inside the energy store 7.
- the flange portion 8 of the torsional vibration damper 5 is formed as a ring member 9 and received by means distributed over the circumference rivets 10 on the friction clutch 6.
- the pitch of the rivets 10 is adjusted over the circumference so that they are synchronous to the bolt circle of the friction clutch 6.
- the rivets 10 can be used at the same time for riveting the friction clutch 6 with the secondary flywheel 4.
- the rivets 10 may be riveted circumferentially adjacent the riveting of the friction clutch 6 to the secondary flywheel 4 in separate mounting holes of the secondary flywheel.
- Figure 2 shows the torsional vibration damper 5 in view.
- Flange part 8 takes in the embodiment shown six distributed over the circumference Tilgermassencovere 12, which are each formed of two axially opposing absorber masses 11. Between the Tilgermassencoveren 12, the axially aligned rivets 10 are provided, which are riveted to the secondary flywheel 4 ( Figure 1), so that the riveting of the centrifugal pendulum takes place at the same radial height as the absorption of the absorber mass pairs 12 on the flange 8. In this way, a torsional vibration damper 5 can be proposed with low radial space requirements.
- the rivets 10 may have annular discs 14, which may serve as a stop buffer 15, and may be made of elastic material such as rubber, rubber such as HNBR, NBR or the like.
- Figure 3 shows the torsional vibration damper 5 in an exploded view with the flange 8, the rivets 10 with the annular discs 14 and the absorber masses 11 and spacers 16 as spacers, by means of which the axially opposing absorber masses 11 are interconnected.
- the Tilgermassensectione 12 thus formed (Figure 2) are received limited pivotally on the flange 8.
- the rolling elements 13 designed as cylindrical rollers 17 roll on the raceways 18, 19 formed by cutouts in the absorber masses 11 and in the flange part. Between the cutouts, a single opening 20 is provided for the spacer elements 16.
- the spacer elements 16 can therefore be arranged closer to one another, so that the opening 20 requires less installation space than a plurality of individual openings, as a result of which the cutouts of the raceways 18 are closer to one another. can be arranged and thus the number of absorber masses 11 can be increased over the circumference can be increased.
- the spacer elements 16 receive between them the stop buffer 21, which can be used alternatively or in addition to the annular discs and formed from the same material. In an additional arrangement, for example, multi-stage impact behavior can be achieved.
- the spacing of the absorber masses 11 from the flange part 8 takes place through the cover disks 22.
- Figure 4 shows the torsional vibration damper 5a according to the invention, which can replace the torsional vibration damper 5 of Figures 1 to 3 in the embodiment shown and is also suitable for other embodiments, in partial view.
- the center of gravity S of the absorber masses 11a is arranged radially outside the raceways 18a of the flange part 8a and the hidden raceways 19a of the absorber masses 11a, which are therefore only shown in dashed lines.
- the center of gravity S results essentially from the shape of the absorber masses 11a.
- the raceways 18a, 19a are therefore displaced inwardly so that both the drawn between the radially outer contact surfaces 29 of the arranged in the flange portion raceways 18a first line 23 and drawn between the radially inner contact surfaces 30 of the provided in the absorber masses 11a raceways second Line 24 lies radially within the center of gravity S.
- a stable pendulum balance is attained when starting the flange part 8a for an absorber mass pair 12a which is supported inwardly over the raceway 19a by self-stabilizing it by the center of gravity S provided radially outside the raceways 19a is.
- the flange part 8a As an output-side flange part of a dual-mass flywheel with energy stores arranged radially outside the absorber masses 11a, the flange part 8a has radially expanded arms 28 for acting on these.
- the absorber masses have an integrally formed as embossed nose 31, which serves as a captive 32 for the rolling elements 13a.
- an absorber mass pair 12a can be formed entirely of metal and only of two absorber masses 11a, the spacer elements 16a and the rolling bodies 13a.
