Detailed Description
Fig. 1 shows a top view of a centrifugal force pendulum 10. The centrifugal force pendulum 10 is designed as a ring-shaped centrifugal force pendulum. The centrifugal force pendulum 10 is mounted so as to be rotatable about a first axis of rotation 15. The centrifugal pendulum 10 has a first disk element 20, a first coupling mass 25 and a second coupling mass 30. Furthermore, the centrifugal force pendulum 10 has a second disk element 35.
The first disk element 20 has an annular section 40 which extends on a first circular path about the first axis of rotation 15. The annular section 40 is configured in the circumferential direction as a continuous ring with a constant radial width. Of course, the annular section 40 may also have interruptions or varying widths. Radially outside the ring section 40, the first disk element 20 has a first coupling connection 45. The first coupling connection 45 is connected radially on the outside to the ring segment 40. Preferably, the first coupling connection 45 and the ring segment 40 are constructed in one piece and from one piece of material.
The second disk element 35 is arranged in an annular manner about the first axis of rotation 15. The second disc element 35 has a constant radial width. Here, in this embodiment, the second disk element 35 is arranged, by way of example, radially outside the ring segment 40.
The first coupling mass 25 is arranged axially adjacent to the second disk element 35. In this embodiment, the first coupling mass 25 can be embodied, for example, in two parts, so that the first coupling mass 25 has two coupling mass parts in the axial direction, which are arranged on both sides of the second disk element 35. The first coupling mass 25 can be designed in accordance with the type of an external centrifugal pendulum. It is of course also conceivable for the second disk element 35 to have axially spaced apart flanges which are connected to one another, wherein the first coupling mass 25 is arranged axially between the two flanges.
The annular section 40 has a fastening region 46 on the radially inner side. In the fastening region 46, for example, a bore 47 can be provided to connect the ring segment 40 to a torque transmission device, for example a transmission or a torsional vibration damper, in a torque-locking manner. The fixing region 46 may also be arranged on the second disk element 35.
The first coupling mass 25 has a first connecting section 55 and a first mass section 60 connected to the first connecting section 55. The first mass section 60 is radially wider than the first connecting section 55 of the first coupling mass 25.
The first connecting section 55 is configured in the exemplary manner of a crescent. Here, the first connection section 55 is arranged on the side facing the first coupling connection 45. The first mass section 60 is arranged on the side of the first coupling mass 25 facing away from the first coupling connection 45 and is substantially curved. In this embodiment, the first connection section 55 and the first mass section 60 are constructed in one piece and integrally of material.
In this embodiment, the second coupling masses 30 are arranged, for example, mirror-symmetrically with respect to a plane of symmetry 65, wherein the plane of symmetry 65 runs centrally through the first coupling connection 45 and the first axis of rotation 15 is also arranged running in this plane of symmetry 65.
The second coupling mass 30 has a second connecting section 70 and a second mass section 75. The second mass section 75 is formed radially wider than the second connecting section 70. The second connection section 70 is arranged circumferentially on the side facing the first coupling connection 45. A second mass section 75 is arranged in the circumferential direction on that side of the second coupling mass 30 which faces away from the first coupling connection 45. The second connecting section 70 is of crescent-shaped design, while the second mass section 75 is of substantially arcuate design. In this embodiment, the second connecting section 70 and the second mass section 75 are constructed in one piece and from one piece of material.
The first connection section 55 is rotatably fixed to the first coupling connection 45 by means of a first coupling device 80. The first coupling device 80 can be configured as a joint and can have, for example, a rolling bearing or a plain bearing. Preferably, the first coupling device 80 has a needle bearing.
The first mass section 60 is mounted pivotably on a second circular path 90 about a second axis of rotation 95 by means of a first coupling device 80. The second rotation axis 95 is arranged radially outside the first rotation axis 15. The second axis of rotation 95 runs parallel to the first axis of rotation 15.
The second connecting section 70 is connected with the first coupling connection 45 at the end facing the first coupling connection 45, offset in the circumferential direction from the first coupling means 80, by means of a second coupling means 85. In this embodiment, the second coupling device 85 is of the same design as the first coupling device 80. In order to avoid axial misalignment of the first coupling mass 25 with the second coupling mass 30, the first coupling means 80 is arranged circumferentially offset from the second coupling means 85. As a result, the centrifugal force pendulum 10 can be designed particularly narrow in the axial direction.
The second coupling device 85 supports the second coupling mass 30 so that it can rotate about the third axis of rotation 100. The third axis of rotation 100 is circumferentially offset from the second axis of rotation 85. Furthermore, the third axis of rotation 100 and the second axis of rotation 95 are arranged on a third circular track 105 around the first axis of rotation 15. The second coupling device 85 can be designed as a joint like the first coupling device 80, for example, and can have a plain bearing or a rolling bearing, for example. Other designs are also conceivable. The second mass section 75 is pivotable in rotation on a fourth circular path 110 about the third axis of rotation 100 by means of the second coupling device 85.
The second connecting section 70 is connected with the first coupling connection 45 at the end facing the first coupling connection 45, offset in the circumferential direction from the first coupling means 80, by means of a second coupling means 85. As a result, the centrifugal force pendulum 10 can be designed particularly narrow in the axial direction. In this embodiment, the second coupling device 85 is of the same design as the first coupling device 80.
Furthermore, the centrifugal force pendulum 10 has a first link guide 115 and a second link guide 120. The first gate guide 115 is arranged offset in the circumferential direction from the first coupling device 80. This results in the first coupling connection 45 being arranged circumferentially between the first and second link guides 115, 120. The first link guide 115 connects the first mass section 60 and the second disk element 35.
The rotational irregularities are introduced into the first disk element 20 via the fastening section 46 and are transferred from the first disk element 20 via the ring section 40 to the first coupling connection 45, wherein the rotational irregularities are introduced into the first and second coupling masses 25, 30 by means of the first and second coupling devices 80, 85. The rotational irregularities can be generated by the internal combustion engine and are superimposed on the torque provided by the internal combustion engine for driving the vehicle, for example.
The first gate guide 115 has a first opening 125, which is arranged in the first coupling mass 25. The first opening 125 is configured in a kidney shape having a center of curvature disposed radially outward of the first opening 125. The first opening 125 is disposed in the first mass section 60. In the second disc element 35, the first gate guide 115 has a second opening 130. The second opening 130 is also kidney-shaped and has a center of curvature, around which the second opening 130 is guided, which is arranged radially inside the second opening 130. The second opening 130 is shown in phantom in fig. 1.
Further, the first chute guide 115 includes a first guide roller 135. The first guide roller 135 penetrates the first opening 125 and the second opening 130. Furthermore, the first guide roller 135 rolls on the first opening contour of the first opening 125 and on the second opening contour of the second opening 130 and at the same time guides the first coupling mass 25 along the first pendulum track 136. Furthermore, the first gate guide 115 couples the second disk element 35 to the first coupling mass 25, so that when rotational irregularities are introduced into the first disk element 20, the first coupling mass 25 swings out of the first rest position along the first swing path 136 and at the same time the second disk element 35 acts on the first coupling mass 25 via the first gate guide 115. The second disk element 35 serves here as a flywheel mass. The second disk element 35 performs a pivoting movement only in the circumferential direction on a fifth circular path about the first axis of rotation 14 as a result of the entrainment of the first coupling mass 25. Furthermore, in the pivoting movement along the first pendulum path, the first coupling mass 25 pivots about the second axis of rotation 95 relative to the first coupling connection 45 along the second circular path 95.
The second link guide 120 is basically configured the same as the first link guide 115. The second chute guide 120 has a third opening 140 and a fourth opening 145 (shown in phantom in fig. 1). The third opening 140 is kidney-shaped and is arranged in the second mass section 75 of the second coupling mass 30. The third opening 140 has a center of curvature, which is disposed radially outward of the third opening 140. The fourth opening 145 is arranged in the second disk element 35. The fourth opening 145 is configured in a kidney shape in which a center of curvature of the fourth opening 145 is arranged radially inside the fourth opening 145. The second chute guide 120 further has a second guide roller 150, wherein the second guide roller 150 penetrates the third opening 140 and the fourth opening 145. In this case, the second guide roller 150 rolls over the third opening contour of the third opening 140 and over the fourth opening contour of the fourth opening 145 and guides the second coupling mass 30 along the second pendulum track 155 when introducing rotational irregularities into the second coupling mass 25. When the second coupling mass 30 is pivoted along the second pivot path 155, the second coupling mass executes a movement along the fourth circular path 110 with reference to the third axis of rotation 100 and the first coupling connection 45.
In this embodiment, the first coupling masses 25 are connected to the same first coupling connection 45 via the first coupling means 80 and the second coupling masses 30 are connected to the same second coupling connection 85. This results in the first coupling connection 45 being arranged circumferentially between the first and second link guides 115, 120.
In this embodiment, the first coupling connection 45 has a first section 160 arranged radially on the inside and a second section 165 arranged radially on the outside on the first section 160. The first segment 160 has a first side 170 and a second side 175 circumferentially disposed relative to the first side 170. The first side surface 170 and the second side surface 175 extend parallel to each other in the circumferential direction. Radially on the outside, a second section 165 is arranged on the first section 160. The second section 165 tapers radially outward. It is particularly advantageous if the first coupling means 80 and the second coupling means 85 are arranged radially on the outside on the first section 160 or radially on the inside on the second section 165, preferably radially on the middle on the second section 165. Furthermore, the mass of the first disk element 20, which has only a slight damping effect on rotational irregularities, is kept low by the second radially tapering section 165.
In this embodiment, the centrifugal force pendulum 10 has, by way of example, a third coupling mass 180 and a fourth coupling mass 185. In addition, the first disk member 20 has a second coupling connection 190. The second coupling connector 190 is arranged offset in the circumferential direction, for example by 180 ° about the first axis of rotation 15, relative to the first coupling connector 45. It is also conceivable for the second coupling connection 190 to enclose another angle with the first coupling connection 45. It is also conceivable, for example, for the second coupling connection 190 to be arranged offset by 120 ° with respect to the first coupling connection 45. Radially inward, the second coupling connection 190 is connected with the ring segment 40. Preferably, the ring section 40, the first coupling connection 45 and the second coupling connection 190 are constructed in one piece and from one piece of material. It is also conceivable for the first disk element 20 to be designed in multiple parts, so that the first disk element 20 is arranged axially on both sides of the second disk element 35.
The third coupling mass 180 is constructed identically to the second coupling mass 30, and the fourth coupling mass 185 is constructed identically to the first coupling mass 25. The third coupling mass 180 is connected to the second coupling connection 190 by a third coupling device 195. The fourth coupling means 200 couples the fourth coupling mass 185 with the second coupling connection 190. The third and fourth coupling devices 195, 200 are of identical construction to the first and second coupling devices 80, 85 and are arranged extending on a third circular path 105 around the first axis of rotation 15.
In this embodiment, the first coupling connection 45 and the second coupling connection 190 are identically constructed. It is of course also conceivable for the second coupling connection 190 to be constructed differently from the first coupling connection 45.
Fig. 2 shows a top view of the centrifugal force pendulum 10 shown in fig. 1, which is shown in fig. 1. Fig. 2 shows the forces acting essentially during operation of the centrifugal force pendulum 10.
In operation, the centrifugal force pendulum 10 rotates about the first axis of rotation 15 at an angular velocity ω1And (4) rotating. First mass distance Y due to the rotation about first axis of rotation 15 and first mass center of gravity 205 of first coupled mass 25S1So that the first centrifugal force FZ1Acting on the first coupling mass 25.
If rotational irregularities, for example from an internal combustion engine, are introduced into the first disk element 20, the first angular velocity ω of the first disk element 201A first angular velocity ω relative to the second disc element 35 acting as a flywheel mass1And (6) changing. First angular velocity ω of the first disc member 201The change relative to the second disk element 35 causes the first coupling mass 25 to pivot about the second rotational axis 95 along the second circular path 90 and the first pendulum path 136 by means of the first link guide 115.
By pivoting about the second axis of rotation 95, the second centrifugal force F about the second axis of rotation 95Z2Acting on the first coupling mass 25. Pivoting about the second axis of rotation 95 at a second angular velocity ω2The process is carried out. Simultaneously, the first coupling mass 25 moves along the first pendulum track 136 and is deflected inward by rotational irregularities from a rest position, which corresponds to the radially outermost position of the first coupling mass 25. By moving inwardly along the first swing rail 136The pivoting and coupling of the first coupling mass 25 to the second disk element 35 generates a first reaction moment MG1. First reaction moment MG1Acts on the first coupling mass 25 and moves the first coupling mass 25 from the offset position into the rest position again.
Second centrifugal force FZ2By a distance R between first mass center of gravity 205 and second axis of rotation 95S1Acts on the first coupling means 80, wherein a first distance R from the second axis of rotation 95 is formed by the first mass center of gravity 205S1The resultant first force F acts on the first coupling means 80ZR2.1. Resultant first force FZR2.1Acting perpendicular to the plane in which the first and second axes of rotation 15, 95 are arranged.
A second distance R from the first axis of rotation 15 by means of the second axis of rotation 95L2The resultant first force FZR2.1As a first moment M1Acting on the first coupling connection 45.
The forces acting on the second coupling mass 30 extend mirror-symmetrically with respect to the plane of symmetry 65. By means of a mirror-symmetrical design, the first coupling mass 25 and the second coupling mass 30 also have the same mass and have a mirror-symmetrical center of gravity position.
During operation of the centrifugal force pendulum 10, the third centrifugal force FZ3Acting on the second coupling mass 30. Third centrifugal force FZ3Acting radially outward from the first axis of rotation 15 on the second coupling mass 30. First angular velocity ω of the first disc member 201Due to the change in rotational irregularities relative to the second disk element 35, the second coupling mass 30 is pivoted about the third rotational axis 100 along the second pendulum path 155 by means of the second link guide 120.
Pivoting about the axis of rotation 100 at a third angular velocity ω3The process is carried out. By pivoting about the third axis of rotation 100, the fourth centrifugal force FZ4Acting on the second coupling mass 30 about the third axis of rotation 100. Simultaneously, the second coupling mass 30 moves along the second pendulum path 155 and is deflected inward from the rest position by rotational irregularities. By pivoting along the second swing rail 155And the coupling of the second coupling mass 25 to the second disk element 35 generates a second reaction moment MG2. Second reaction moment MG2Acts on the second coupling mass 30 and moves the second coupling mass 30 from the deflected position into the rest position again. First and second reaction moments MG1、MG2Acting in the same direction in the circumferential direction around the first axis of rotation 15.
Fourth centrifugal force FZ4By a third distance R between the second mass center of gravity 210 and the third axis of rotation 100S2Acting on the second coupling means 85, wherein the third distance R is passedS2The resultant second force F is applied to the second coupling means 85ZR4.2Acting on the second coupling mass 30. Resultant second force FZR4.2The plane which is arranged perpendicular to the first and third axes of rotation 15, 100 functions.
A fourth distance R from the first axis of rotation 15 by the third axis of rotation 100L4Resultant second force FZR4.2As a second moment M2Acting on the first coupling connection 45.
Since the first coupling mass 25 and the second coupling mass 30 are arranged in opposite directions on the first coupling connection 45, the resultant first force FZR2.1And resultant second force FZR4.2The opposite acts and is thereby counteracted. Likewise, the first moment M1And a second moment M2And (4) counteracting. This causes a restoring moment M of the first and second coupling masses 25, 30G1、MG2Circumferentially independent of the direction of rotation.
Thereby avoiding the reset moment MG1、MG2Direction-dependent decrease of. Furthermore, a uniform pivoting of the coupling masses 25, 30 along the respective pivot path 136, 155 is ensured irrespective of the rotational direction of the rotational irregularities. Furthermore, the first coupling connection 45 is not subjected to a bending load, so that the first coupling connection 45 can be constructed particularly simply and cost-effectively. Furthermore, the centrifugal force pendulum 10 shown in fig. 1 and 2 acts uniformly in both circumferential directions.
The effects described by way of example for the first and second coupling masses 25, 30 also apply to the second coupling connection 190 and the third and fourth coupling masses 180, 185 arranged thereon.
