Definitions
- the invention relates to a torsional vibration damper with a receiving part which rotates about an axis of rotation and a plurality of pivotable absorber masses arranged on the circumference thereof.
- Generic torsional vibration damper for example, become known as a centrifugal pendulum and are housed in partially radially confined spaces.
- DE 196 31 989 C1 discloses for this purpose a torsional vibration damper whose absorber masses are provided with outer contours, which are formed by a single radius.
- the object of the invention is therefore the development of a torsional vibration damper with a given installation space increased total mass of several arranged over the circumference of the receiving part absorber masses.
- the invention is characterized by a torsional vibration damper with a arranged around a rotational axis receiving part having a predetermined outer circumference and a plurality of runners in the receiving part radially and circumferentially limited pivotable absorber masses with a radially outer contour and a radially inner inner contour extending over a circumferential segment of the receiving part extend, dissolved, wherein the outer contour is limited during a displacement of the absorber mass along the raceways on the outer circumference of the receiving part and the outer contour and / or inner contour relative to a rotation angle about the axis of rotation have different radii.
- Such an embodiment of the outer contours of the absorber masses can be crowned depending on the number of different, applied over the course of the outer contour in the circumferential direction outer contour radii and form an individual, not a single outer contour radius describing curve.
- this curve is adjusted via the pivot angle of the absorber mass to the outer periphery of the receiving part, that no radial exceeding of the TiI
- the radially outermost region of the absorber mass is maximally approximated during its pivoting to the outer circumference of the receiving part, so that over the entire circumference of the absorber mass, the outer contour preferably has the same minimized distance of the radially outermost region to outer circumference, without at an operating point stand during the pivoting of the absorber mass beyond the outer circumference. Due to this maximum approach of the absorber masses to the outer circumference of the receiving part at all operating points, the carrier masses can absorb more mass than when using a single outer contour radius.
- the outer contour is dependent on the design of the introduced into the receiving part raceways in which the absorber masses are pivotally received by they shift depending on the vibration conditions occurring radially and circumferentially in a conventional manner.
- the raceways are adapted to the vibration problems to be solved.
- a first advantageous approach may provide that a middle segment of the outer contour has a larger outer contour radius than the outer contour radii of end-side segments. In this way, a flatter than a single outer contour radius profile of the outer contour is achieved, so that in the end segments additional mass can be provided, as has been shown that in a variety of applications, the outer contours with a single outer contour radius at large Verschwenkwinkeln an enlargement of the Have distance of the radially outer region relative to the outer periphery of the driving part.
- the outer contour radii of the end segments are advantageously the same. Tuned to particular vibration problems torsional vibration damper can also provide absorber masses with an asymmetric arrangement of the outer contour radii.
- the configuration of the outer contour is advantageously carried out by the rotation angle about the axis of rotation, wherein the outer contour radii over the outer contour extending defined with respect to the axis of rotation as the center, so that the course of the outer contour over the circumference in a polar coordinate system by specifying the outer contour radius depending on the rotation angle can be described about the axis of rotation. It has further been shown to be advantageous if outer contour radius and angle of rotation are predefined as a function of the pivot angle of the absorber masses relative to the receiving part about a pivot center. Furthermore, it may be advantageous if the outer contour is provided as a function of a swivel radius of the absorber masses pivoting about the pivot center.
- the outer contour radius of the outer contour which is dependent on the angle of rotation, can be provided as a function of the number of absorber masses distributed over the circumference.
- the pitch angle itself for example, when using four absorber masses 90 °, or a maximum pivot angle of the absorber masses plus a distance between the two absorber masses can be specified as the input variable.
- an advantageous torsional vibration damper is provided with an outer contour, in which the outgoing from the axis of rotation outer contour radius of the outer contour of a predetermined number distributed over the circumference of the receiving part to a neutral position relative to the receiving part within a maximum pivot angle with a pivot angle and a pivot radius relative to the receiving part distributed absorber masses and depending on the angle of rotation is formed.
- a particularly advantageous embodiment provides the aforementioned input variables in the following mathematical context, wherein the outer contour in a polar coordinate system depending on the outer contour radius Rj and the rotation angle cij are shown:
- R max radius of the absorption part ßmax maximum swing angle of the absorber mass, ßi tilt angle of the absorber mass, n number of absorber masses distributed over the circumference, I swivel radius of the absorber masses.
- Equations (1) and (2) are complemented by the variables of equations (3) to (5), and equation (5) is complemented by equation (6).
- the outer contour radii R 1 are assigned to the outer contour as a function of the rotational angle ⁇ i. Furthermore, these depend on the division of the absorber masses, ie on the number of absorber masses distributed uniformly over the circumference.
- the inner contour of the absorber masses is also adapted so that the effective mass of the absorber mass can be increased by advantageously utilizing the conditions dictated by the installation space.
- the receiving part is a function carrier for further functions.
- the receiving part can be accommodated as part of the torsional vibration damper in a complex Schwingungsdämpfer adopted, for example in a dual-mass flywheel, in a housing of a torque converter or other arrangements.
- the space available for accommodating the carrier masses on the receiving part is generally limited to an annular space having an outer and an inner circumference.
- an inner contour delimiting the absorber mass radially inwards can be formed from a respective circular segment extending from a neutral position of the absorber mass in both circumferential directions.
- the circle segments can be separated from one another by a straight line section extending over a predetermined length.
- the inner contour radii of the two circular segments have a center which is formed by an intersection of a pivoting radius of the absorber mass drawn around the axis of rotation and the maximum pivoting angle applied about the axis of rotation.
- the inner contour radius of the two circle segments is greater than the inner circumference of the available space and therefore larger than a space limit of the receiving part.
- the absorber mass is limited in an advantageous manner in the circumferential direction by outer and inner contours on both sides of the absorber mass connecting side contours, wherein the Side contours are spaced from each other by a pitch angle minus a safety distance.
- the pitch angle is preferably defined by the number of absorber masses arranged over the circumference of the receiving part.
- At least one side contour is arranged parallel to a line arranged around a center point, wherein the center point is formed by an intersection of a pivot radius of the absorber mass drawn around the rotation axis and the maximum pivot angle applied about the axis of rotation.
- at least one side contour is circular in sections.
- FIG. 4 shows a systematic elevation of a damper mass of a torsional vibration damper in a further embodiment.
- Figure 5 detail A of Figure 4 in an enlarged view.
- FIG. 1 shows the outer contour A of an absorber mass 1 in a solid line.
- the remaining lines are purely geometrical in nature and, since they do not necessarily have to correspond to the structural lines of the torsional vibration damper, are shown by dashed lines.
- the absorber mass 1 is arranged within a division of the drive part in the circumferential direction, which corresponds to an angle of 90 ° in the illustrated embodiment, so that four absorber masses 1 are arranged on the receiving part over the circumference of the torsional vibration damper.
- the radius R max indicates the outer circumference of the receiving part about the rotation axis 2.
- the absorber mass 1 can be pivoted relative to the receiving part about the zero line 3 on both sides by the swivel angle ⁇ i between the values 0 ° and ⁇ max with a swivel radius I.
- the dependencies of radius R max , the maximum pivot angle ⁇ max , the pivot angle ⁇ i and the pivot radius I result in the advantageous outer contour A being outer contour radii R 1 which depend on the angle of rotation ⁇ i.
- the outer contour A is characterized by an advantageous course, in which over the entire pivoting range of the absorber mass 1 relative to the receiving part of the distance of the outer contour A to the radius R max at the height of the zero line 3 is minimal.
- Such an outer contour can be produced with numerically guided processing machines with little effort. For example, a so-called CNC milling machine can be programmed to such an outer contour and produce the absorber masses directly or a tool for punching them.
- Figure 2 shows the formation of the inner contour U of the absorber mass 1 in accordance with the figure 1 shown manner.
- the inner contour U is formed by two circle segments 4 with an inner contour radius R u .
- the circle segments 4 are separated in the region of the zero line 3 by a linear line segment which preferably has the condition 0 ⁇ b ⁇ 2 / sin /? max met.
- the centers P of the inner contour radii R 11 are defined by the maximum pivoting angles ⁇ max on a circle displaced radially about the pivoting radius I within the axis of rotation 2 of the receiving part.
- the inner contour radii R u correspond to the radius R m j n of the inner circumference of the receiving part, or its available space at the corresponding radius.
- FIG. 3 shows a representation of the side contours S similar to FIGS. 1 and 2.
- the shape of the side contours is formed by the dividing lines 5 resulting from the division of the receiving part, starting from the midpoints P defined in FIG. 2 at the division angle Y to the zero line 3 to be pulled.
- the side contours S are oriented at the distance c, which is designed for safe spacing of the adjacent absorber masses within the limits of the permissible component tolerances and to avoid collisions, at the dividing lines 5.
- a systematic elevation of a damper mass of a torsional vibration damper in a further embodiment is shown in FIG. 4 and FIG.
