Description
Technical Field
The invention relates to a centrifugal pendulum device, in particular for a drive train of a motor vehicle.
Background
Centrifugal force pendulum devices are known in the prior art, for example from DE 10 2006 028 552 A1 or from DE 10 2014 211 711 A1.
The centrifugal pendulum device according to the prior art has at least one rotatably arranged support flange and a pendulum mass which is articulated on the support flange and is supported so as to be displaceable relative to the at least one support flange, wherein the pendulum mass is guided so as to be displaceable relative to the at least one support flange by means of guide tracks in the respective pendulum mass and in the at least one support flange, such that at least one roller element engages in the guide tracks of the pendulum mass and of the at least one support flange in order to support the pendulum mass in displacement relative to the at least one support flange.
In this case, with low rotational speeds and high torques, the pendulum mass can strike a stop at the end of its path of motion, which leads to undesirable noise and can also damage the centrifugal pendulum device. In the event of the pendulum mass striking the boundary of the oscillation space of the pendulum mass, the effect of torsional damping or torsional damping is temporarily lost, since the oscillation of the pendulum mass is disturbed.
DE 10 2014 211 711 A1 discloses a centrifugal pendulum device with a pendulum mass between two carrier flanges, which are loaded in the axial direction by means of contact elements loaded by spring elements in order to load the pendulum mass against one of the carrier flanges in order to promote a defined friction between the pendulum mass and the carrier flange.
An elastomeric ring may be radially contained therein to additionally dampen the end impact of the pendulum mass. But this construction is more likely to be costly.
Disclosure of Invention
The object of the present invention is to provide a centrifugal force pendulum device which is improved over the prior art and has improved impact damping of the pendulum mass or avoids the impact of the pendulum mass.
This object is achieved by the features of claim 1.
An embodiment of the invention relates to a centrifugal pendulum device with at least one carrier flange which can be rotatably fixed, and at least one pendulum mass which is hinged to the carrier flange and is supported in a manner which can be displaced relative to the at least one carrier flange, wherein the pendulum mass is guided in a manner which can be displaced relative to the at least one carrier flange by means of guide tracks in the respective pendulum mass and in the at least one carrier flange, such that at least one roller element engages in the guide tracks of the pendulum mass and in the at least one carrier flange, respectively, in order to support and guide the displacement of the pendulum mass relative to the at least one carrier flange, wherein at least one spring element is provided which is arranged axially between one of the carrier flanges and the pendulum mass and which is supported axially on both the carrier flange and on the at least one pendulum mass or on the plurality of pendulum masses, and wherein at least one axially extending projection is provided in the at least one pendulum mass in the radial direction, and at least one projection is supported for the purpose of damping the impact area. Friction can thereby be applied to the pendulum mass, which reduces the kinetic energy of the pendulum mass in order to damp or avoid impacts on the end regions of the movement path of the pendulum mass, wherein an impact damper is additionally provided by axially extending projections. Damping or dampening of torsional vibrations is thus generally improved, as failure of the damping or dampening due to severe impact is reduced or avoided.
In one embodiment, it is also expedient if two support flanges are provided which are arranged at a distance from one another in the axial direction, wherein at least one pendulum mass, preferably at least two or three pendulum masses, are arranged in an axially displaceable manner between the two support flanges. The pendulum mass can thus be applied on one side or better also on both sides in order to promote friction.
In a further embodiment, it is also advantageous if spring elements are arranged on both sides of the pendulum mass, which spring elements each apply an axially disposed pendulum mass, wherein the respective spring element is supported on one of the support flanges on one side and on the other side on the pendulum mass. The respective pendulum mass is thereby not loaded towards the respective carrier flange, but rather is centrally loaded by the respective spring element. Thus, when both the spring element and the pendulum mass are formed of steel, a defined friction is created, for example a steel-steel friction of two friction pairs each of steel.
It is also advantageous if the respective spring element is positively connected to the adjacently arranged support flange, so that it is connected to the support flange in a rotationally fixed manner.
In one embodiment, it is particularly advantageous if the respective spring element is a ring element having a tongue or a receptacle for a positive, rotationally fixed connection to the respective carrier element.
It is particularly advantageous if the respective spring element can be rotated or moved in the circumferential direction relative to the respective pendulum mass and is brought into frictional contact with the respective pendulum mass. The spring element is thereby locked in the circumferential direction relative to the support flange and can be displaced relative to the moving or movable pendulum mass, or vice versa.
In one embodiment, it is also advantageous if the axially extending projection is formed by one of the support flanges and protrudes radially inwardly from the support flange as an annular sleeve in the axial direction. The projection is thus formed integrally with one of the carrier flanges, which increases the functionality of the carrier flange and reduces the number of parts.
It is also particularly advantageous if the axially extending projections carry plastic or elastomer elements which are then provided for damping shocks and/or for generating friction against the pendulum mass. The violent impact of the pendulum mass on the end region of the movement track is thus reliably prevented.
It is also expedient if the plastic or elastomer element has a circumferential groove in which the sleeve engages. The plastic or elastomer element is thus safely arranged on the axially extending projection and is held in a defined manner without the risk of leakage over the service life.
It is also advantageous if the respective pendulum mass carries radially inward a friction and/or sliding element for supporting on the axially extending projection. Such friction and/or sliding elements are preferably embodied as spherical elements, which are held in a torsionally stable manner on the respective pendulum mass. Alternatively, roller elements or the like may also be provided.

Detailed Description
Fig. 1 to 4 show a first embodiment of a centrifugal force pendulum device 1 in different views, while fig. 5 and 6 show a second embodiment of a centrifugal force pendulum device 1 in different views.
The centrifugal force pendulum device 1 of fig. 1 to 4 has two carrier flanges 2 which are designed as disk-shaped elements and are arranged parallel to one another. Three pendulum masses 3 are arranged in a displaceable manner in the axial direction between the two carrier flanges. Alternatively, more or fewer pendulum masses 3 can be provided. The two support flanges 2 are connected in a defined, spaced-apart manner to one another by means of spacer bolts 7. In the exemplary embodiments of fig. 1 to 4, it is particularly expedient if two support flanges 2 are provided which are arranged at a distance from one another in the axial direction, wherein, for example, three pendulum masses 3 are provided which are arranged between the two support flanges 2 in an axially displaceable manner.
The at least one support flange 2 can be rotatably fastened to the drive train, so that it can be rotated in a driven manner.
At least one pendulum mass 3 or a plurality of pendulum masses 3 are articulated to one carrier flange 2 or to a plurality of carrier flanges 2, so that the pendulum masses are supported so as to be displaceable relative to at least one carrier flange 2 or to both carrier flanges.
The pendulum mass 3 or pendulum masses 3 are each guided in such a way that they can be displaced relative to the at least one carrier flange or the two carrier flanges 2 by means of guide rails 4 in the respective pendulum mass 3 and by means of guide rails 5 in the at least one carrier flange 2 or the two carrier flanges 2, so that at least one roller element 6 engages in each of the guide rails 4 of the pendulum mass 3 and in each of the guide rails 5 of the respective carrier flange 2 in order to support and guide the displacement of the respective pendulum mass 3 relative to the at least one carrier flange 2 or the plurality of carrier flanges 2. In the embodiment of fig. 1 to 4, two guide rails 4 are provided per pendulum mass 3, respectively, so that two roller elements 6 per pendulum mass 3 support the pendulum mass 3.
Furthermore, according to the invention, at least one spring element 8 is provided, which is arranged axially between one of the support flanges 2 and one of the pendulum masses 3 and which is supported axially both on the support flange 2 and on the at least one pendulum mass 3 or on a plurality of pendulum masses 3. According to fig. 1 to 4, two spring elements 8 are arranged in the illustrated embodiment, wherein each spring element 8 is arranged between one of the support flanges 2 and the three pendulum masses 3, wherein the two spring elements 8 are arranged on each side of the pendulum mass 3.
In the exemplary embodiment shown, spring elements 8 are arranged on both sides of the pendulum mass 3, which spring elements each axially load the pendulum mass 3 provided. The pendulum mass 3 is applied here away from the respective support flange 2. The respective spring element 8 is supported on one side on one of the carrier flanges 2 and on the other side on the pendulum mass 3. In the exemplary embodiment shown, the respective spring element 8 is supported radially on the inside on one of the carrier flanges 2 and radially on the outside on the pendulum mass 3.
The respective pendulum mass 3 is accordingly not loaded against the respective carrier flange 2, but rather is centrally loaded by the respective spring element 8. Thus, when both the spring element 8 and the pendulum mass 3 are formed from steel, a defined friction is created between the spring element 8 and the pendulum mass 3, for example a steel-steel friction of two friction pairs each of steel.
Fig. 1 also shows that the respective spring element 8 is positively connected to the adjacently arranged support flange 2 by means of the spacer bolts 7, so that the spring element 8 is connected to the support flange 2 in a rotationally fixed manner. The spring element 8 has a radially outwardly arranged tongue 9 with a radially outwardly open recess 10 formed therebetween, into which the spacer screw 7 can be partially inserted in order to prevent rotation of the spring element 8 relative to the spacer screw 7 and thus relative to the support flange 2.
Fig. 1 to 4 show that the respective spring element 8 is formed as an annular element with a tongue 9 and/or a receptacle 10 for a positive, rotationally fixed connection to the respective carrier element 2.
Since the pendulum mass 3 moves or rotates relative to the carrier flange 2, it is also advantageous if the respective spring element 8 can rotate or move in the circumferential direction relative to the respective pendulum mass 3 and is brought into frictional contact with the respective pendulum mass 3. The spring element 8 is thereby locked in the circumferential direction relative to the support flange 2 and can be displaced relative to the moving or movable pendulum mass 3, or vice versa. The defined friction can thus be adjusted.
Furthermore, fig. 1 to 4 show that axially extending projections 11 are provided in at least one pendulum mass 3 or in several pendulum masses 3 in the radial direction, on which projections at least one pendulum mass 3 can be supported at least in part for damping impacts. Friction can thereby be applied to the pendulum mass 3, which reduces the kinetic energy of the pendulum mass 3 in order to damp or avoid impacts on the end regions of the movement path of the pendulum mass 3. Additional impact dampers can also be provided on the projections 11 through the axially extending projections 11 or on the axially extending projections 11. Damping or dampening of torsional vibrations is thus generally improved, as failure of damping or dampening based on severe impact is reduced or avoided.
Fig. 1, 3 and 4 show that the axially extending projection 11 is formed by one of the support flanges 2 and protrudes radially inward from the support flange 2 in the axial direction as an annular sleeve 12. The projection 11 is thus formed integrally with one of the support flanges 2, which increases the functionality of the support flange 2 and reduces the number of parts.
Alternatively, the axially extending projections can carry plastic or elastomeric elements, which, however, cannot be seen in fig. 1 to 4, are provided for damping shocks and/or for generating friction against the pendulum mass 3. The violent impact of the pendulum mass 3 on the end region of the movement track is thus reliably prevented.
However, it can be seen in fig. 1 to 4 that the respective pendulum mass 3 carries radially inward friction and/or sliding elements 13 for supporting on the axially extending projections 11. The friction and/or sliding element 13 is fastened to the underside of the pendulum mass 3 by means of a clip 14, wherein such friction and/or sliding element 13 is provided in each case on both end regions 15 of the pendulum mass 3, viewed in the circumferential direction. The friction and/or sliding element 13 in this case grips the clip 14 at the opening and can rest on the projection 11. Such friction and/or sliding elements 13 are preferably formed as spherical elements which are held in a rotatable manner on the respective pendulum mass 3. Alternatively, roller elements or the like may also be provided.
The centrifugal force pendulum device 1 of fig. 5 and 6 also has two carrier flanges 2, which are designed as disk-shaped elements and are arranged parallel to one another. Three pendulum masses 3 are arranged in a displaceable manner in the axial direction between two carrier flanges 2. Alternatively, more or fewer pendulum masses 3 can also be provided. The two support flanges 2 are connected in a defined, spaced-apart manner to one another by means of spacer bolts 7. In the embodiment of fig. 5 and 6, it is particularly expedient to provide two support flanges 2 which are arranged at a distance from one another in the axial direction, wherein, for example, three pendulum masses 3 are arranged between the two support flanges 2 in an axially displaceable manner. The at least one support flange 2 can be fastened to the drive train in a rotatable manner, so that it can be rotated in a driven manner.
At least one pendulum mass 3 or a plurality of pendulum masses 3 are articulated on one carrier flange 2 or on a plurality of carrier flanges 2, so that the pendulum mass 3 is supported displaceably with respect to at least one carrier flange 2 or with respect to both carrier flanges 2.
The pendulum mass 3 or pendulum masses 3 can be guided displaceably with respect to the at least one carrier flange or with respect to the two carrier flanges 2 by means of guide rails 4 in the respective pendulum mass 3 and by means of guide rails 5 in the at least one carrier flange 2 or in the two carrier flanges 2, so that at least one roller element 6 engages in a respective guide rail 4 of the pendulum mass 3 and in a respective guide rail 5 of the respective carrier flange 2 in order to support and guide the displacement of the respective pendulum mass 3 with respect to the at least one carrier flange 2 or the plurality of carrier flanges 2. In the embodiment of fig. 5 and 6, each pendulum mass 3 is provided with two guide rails 4, so that each pendulum mass 3 has two roller elements 6 supporting the pendulum mass 3.
Furthermore, according to the invention, a spring element 8 is provided, which is arranged axially between one of the support flanges 2 and one of the pendulum masses 3 and which is supported axially both on the support flange 2 and on at least one pendulum mass 3 or on a plurality of pendulum masses 3. The pendulum mass 3 is thereby acted upon away from one of the support flanges 2 toward the other support flange 2. The spring element 8 is supported on one side on one of the carrier flanges 2 and on the other side on the pendulum mass 3.
Accordingly, the respective pendulum mass 3 is loaded against one of the carrier flanges 2. When both the spring element 8 and the pendulum mass 3 or the carrier flange 2 are formed from steel, a defined friction, for example a steel-steel friction of two friction pairs each of steel, is also produced between the spring element 8 and the pendulum mass 3 or between the spring element 8 and the carrier flange 2.
Fig. 5 shows that the spring element 8 is configured as a ring element.
Since the pendulum mass 3 moves or rotates relative to the carrier flange 2, it is also advantageous if the respective spring element 8 can rotate or move in the circumferential direction relative to the respective pendulum mass 3 and is brought into frictional contact with the respective pendulum mass 3. The spring element 8 is thereby locked in the circumferential direction relative to the support flange 2 and can be displaced relative to the moving or movable pendulum mass 3, or vice versa. The defined friction can thus be adjusted.
Fig. 5 and 6 also show that axially extending projections 11 are provided in the radial direction in at least one pendulum mass 3 or in several pendulum masses 3, on which at least one pendulum mass 3 can be supported at least in regions for damping impacts. Friction can thereby be applied to the pendulum mass 3, which reduces the kinetic energy of the pendulum mass 3 in order to damp or avoid impacts on the end regions of the movement path of the pendulum mass 3. Additional impact dampers can also be provided on the projections 11 through the axially extending projections 11 or on the axially extending projections 11. Damping or dampening of torsional vibrations is thus generally improved, as failure of damping or dampening based on severe impact is reduced or avoided.
Fig. 5 and 6 show that the axially extending projection 11 is formed by one of the support flanges 2 and protrudes radially inward from the support flange 2 as an annular sleeve 12 in the axial direction. The projection 11 can thus be formed integrally with one of the carrier flanges 2, which increases the functionality of the carrier flange 2 and reduces the number of parts.
The axially extending projections 11 carry a plastic or elastomer element 20 which is provided for damping impacts and/or for generating friction against the pendulum mass 3. The violent impact of the pendulum mass 3 on the end region of the movement track is thus reliably prevented.
In fig. 5 and 6, it can be seen that the respective pendulum mass 3 does not carry friction and/or sliding elements radially inside, as can be seen in fig. 1 to 4. Instead, only one friction surface 21 is provided. Alternatively, however, friction and/or sliding elements according to fig. 1 to 4 can also be provided.
It is also expedient for the plastic or elastomer element 20 to have a circumferential groove 22, in which the sleeve 12 engages. The plastic or elastomer element 20 is thus safely arranged on the axially extending projection 11 and is held in a defined manner without the risk of leakage over the service life.
