Abstract
Description
[0001] The invention relates to a centrifugal pendulum device according to claim 1 and a torsional vibration damper according to claim 11.
[0002] Centrifugal pendulum devices are known that comprise a pendulum mass unit and a pendulum flange. The pendulum mass unit is coupled to the pendulum flange with limited movement.
[0003] It is an object of the invention to provide an improved centrifugal pendulum device and an improved torsional vibration damper with such a centrifugal pendulum device.
[0004] This object is achieved by means of a centrifugal pendulum device according to claim 1. Advantageous embodiments are specified in the dependent claims.
[0005] According to the invention, it was recognized that an improved centrifugal pendulum device can be provided in that the centrifugal pendulum device can be mounted rotatably about a rotation axis, wherein the centrifugal pendulum device has a first pendulum mass unit, a first pendulum flange, and at least one second pendulum flange arranged partially axially spaced from the first pendulum flange. The first pendulum mass unit is arranged axially between the first pendulum flange and the second pendulum flange. The first pendulum mass unit is coupled with limited movement to at least the first and / or second pendulum flange. Furthermore, at least one third pendulum flange and one second pendulum mass unit are provided. The second pendulum mass unit is coupled with limited movement to at least the third pendulum flange.
[0006] This means that a particularly high damping effect can be achieved by the centrifugal pendulum device even with small installation space dimensions.
[0007] In a further embodiment, the third pendulum flange is arranged axially spaced from the first and / or second pendulum flange. The second pendulum mass unit is arranged at least partially axially between the third pendulum flange and the second pendulum flange. This allows for optimized installation space in the radial direction.
[0008] In a further embodiment, the first pendulum mass unit is coupled to the first and / or second pendulum flange by means of a first guide rail. The second pendulum mass unit is coupled to the second and / or third pendulum flange by means of a second guide rail. The first guide rail is arranged offset in the circumferential direction and / or in the radial direction relative to the second guide rail. This allows the centrifugal pendulum device to be designed to be particularly compact in the axial direction.
[0009] In a further embodiment, the first guide rail is designed to guide the first pendulum mass unit along a first pendulum track. The second guide rail is designed to guide the second pendulum mass unit along a second pendulum track. The first pendulum track is different from the second pendulum track. Preferably, the first pendulum track is matched to a first damper order, and the second pendulum track is matched to a second damper order, wherein the two damper orders are preferably different.
[0010] In a further embodiment, the first pendulum mass unit is designed differently from the second pendulum mass unit, wherein the first pendulum mass unit preferably has a first damper order and the second pendulum mass unit has a second damper order that is different from the first damper order. Alternatively, the first pendulum mass unit has a first damper order and the second pendulum mass unit has a second damper order that is identical to the first damper order.
[0011] In one embodiment according to the invention, at least one of the pendulum mass units comprises a first pendulum mass and at least one second pendulum mass. The two pendulum masses are arranged adjacent to one another in the circumferential direction, a first coupling means being provided, and the first pendulum mass and the second pendulum mass are operatively connected to one another by the first coupling means. This makes it easy to prevent the two pendulum masses from striking one another, so that the centrifugal pendulum device is particularly quiet during operation.
[0012] In a further embodiment, a second coupling means is provided, wherein the second coupling means is operatively connected to the first pendulum mass unit and the second pendulum mass unit. This allows the two pendulum mass units to be excited to oscillate together, and a damper order of the two pendulum mass units can be easily modified.
[0013] In a further embodiment, the first and / or second coupling means comprises at least one spring element, in particular a coil spring. It is particularly advantageous for operation of the centrifugal pendulum device in a reciprocating piston engine with cylinder deactivation if the first pendulum mass unit and the second pendulum mass unit are designed for the same or different damper orders.
[0014] Particularly high torsional irregularities can be eliminated if a fourth pendulum flange is provided, which is arranged at least partially axially spaced from the third pendulum flange. A third pendulum mass unit is provided at least partially axially between the third pendulum flange and the fourth pendulum flange. The third pendulum mass unit is coupled to the third pendulum flange and / or fourth pendulum flange with limited mobility. The cascaded arrangement of pendulum mass units and the coupling to the pendulum flanges allows the radial installation space to be reduced and the installation space to be utilized in the axial direction. Furthermore, reliable support of the pendulum mass units on the pendulum flanges is ensured.
[0015] In a further embodiment, the first and second pendulum mass units are arranged on the same or different diameter relative to the axis of rotation.
[0016] In a further embodiment, the pendulum flanges are connected to one another in a rotationally fixed manner, so that a rotational irregularity can be introduced via the first pendulum flange into the further pendulum flanges via connecting means in order to stimulate the pendulum mass units respectively coupled to the pendulum flange to oscillate along the pendulum path and thus to eliminate the rotational irregularity.
[0017] However, the problem is also solved by a torsional vibration damper according to patent claim 11.
[0018] The torsional vibration damper comprises at least one centrifugal pendulum device which is designed as described above.
[0019] The invention is explained in more detail below with reference to the figures. These show: Fig. 1 a perspective view of a centrifugal pendulum device; Fig. 2 a semi-longitudinal section through the Fig. 1 centrifugal pendulum device shown; Fig. 3 an exploded view of the Fig. 1 and Fig. 2 shown centrifugal pendulum device; Fig. 4 a semi-longitudinal section through a further training of the Fig. 1 shown centrifugal pendulum device; Fig. 5 a section of a cross-section through a further training of the Fig. 1 to 4 shown centrifugal pendulum device in a first operating state; Fig. 6 a section of a cross-section through a further training of the Fig. 1 to 5 in a second operating state; and Fig. 7 a section of a longitudinal section through a further training of the Fig. Centrifugal pendulum device shown in 1 to 6.
[0020] Fig. 1 shows a perspective view of a centrifugal pendulum device 10. Fig. 2 shows a half-longitudinal section through the Fig. 1 centrifugal pendulum device 10 shown. Fig. 3 shows an exploded view of the Fig. 1 and Fig. 2 shown centrifugal pendulum device 10. The following are the Fig. 1 to 3 are explained together.
[0021] The centrifugal pendulum device 10 is part of a torsional vibration damper, wherein the centrifugal pendulum is mounted rotatably about a rotation axis 15. The centrifugal pendulum device 10 comprises a first pendulum flange 20, a second pendulum flange 25, and a third pendulum flange 30. The pendulum flanges 20, 25, 30 can also be referred to as pendulum mass carriers 20, 25, 30. The first pendulum flange 20 is arranged at an axial distance from the second pendulum flange 25, and the second pendulum flange 25 is arranged at an axial distance from the third pendulum flange 30. The first pendulum flange 20 is connected to the second pendulum flange 25 by means of a first connecting means 35. The second pendulum flange 25 is further connected to the third pendulum flange 30 by means of a second connecting means 40.
[0022] The first connecting means 35 (cf. Fig. 3) comprises a plurality of first openings 45, distributed in the circumferential direction at, for example, evenly spaced intervals, arranged in the first pendulum flange 20. Furthermore, second openings 50 are provided in the second pendulum flange 25, arranged axially opposite the first openings 45. A connecting bolt 55 of the first connecting means 55 extends through each of the first openings 45 and the second openings 50. The connecting bolt 55 is riveted at its respective longitudinal end to the first pendulum flange 20 and the second pendulum flange 25, respectively. In order to precisely adjust the distance between the two pendulum flanges 20, 25, the connecting bolt 55 has a thickened section 60 in the center, which has a larger diameter than the first openings 45 and the second openings 50.
[0023] The second connecting means 40 is designed analogously to the first connecting means 35. The second connecting means 40 has third openings 65 arranged in the second pendulum flange 25, which are adjacent in the circumferential direction and have the same diameter as the second openings 50 in the second pendulum flange 25. In the third pendulum flange 30, the second connecting means 40 has fourth openings 70 arranged opposite the third openings 65. A second connecting bolt 75 extends through the third and fourth openings 65, 70. The second connecting bolt 75 is designed to correspond to the first connecting bolt 55 in the embodiment. Alternatively, it is also conceivable for the second connecting bolt 75 to have a different design and, for example, to be longer or shorter in the axial direction than the first connecting bolt 55.
[0024] In the embodiment, the connecting bolt 55, 75 is circular. Of course, it is also conceivable for the connecting bolt 55, 75 to have a different cross-section. It is also conceivable for the connecting bolt 55, 75 to be designed as a rivet bolt, so that the pendulum flanges 20, 25, 30 can be connected to one another if they are at least partially axially adjacent to one another. In this case, the thickened section 60 for spacing the respective pendulum flanges 20, 25, 30 is omitted.
[0025] In the embodiment, the second and third pendulum flanges 20, 25, 30 are essentially disk-shaped with a planar configuration in the radial direction. Of course, it is also conceivable for the pendulum flanges 20, 25, 30, like the first pendulum flange 20, to have a first section 76 and a second section 77 radially adjacent to the first section 76, wherein the first section 76 is arranged offset in the axial direction from the second section 77. The first section 76 can serve to torque-lock the centrifugal pendulum device 10 to other components of a torque transmission device, in particular to other components of a torsional vibration device.
[0026] Axially, a first pendulum mass unit 80 is provided between the first pendulum flange 20 and the second pendulum flange 25. The first pendulum mass unit 80 comprises a first pendulum mass 85 and a second pendulum mass 90. The first pendulum mass 85 is arranged circumferentially adjacent to the second pendulum mass 90. The first pendulum mass 85, like the second pendulum mass 90, is partially annular. The first pendulum mass unit 80 is coupled to the first pendulum flange 20 and also to the second pendulum flange 25 by means of a first slotted guide 95 so as to be movable to a limited extent. The coupling serves to guide the first pendulum mass unit 80 along a first pendulum track 100 when rotational irregularities are introduced into the centrifugal pendulum device 10.
[0027] For this purpose, the first slotted guide 95 has at least one first recess 105 arranged in the first pendulum flange 20. The first recess 105 is kidney-shaped and has a center of curvature that is arranged radially inward of the first recess 105. In the first and second pendulum masses 85, 90, the slotted guide 95 each has, for example, kidney-shaped second recesses 110. The second recesses 110 have a center of curvature that is arranged radially outward of the second recess 110. Furthermore, the slotted guide comprises a third recess 111 arranged in the second pendulum flange 25. The third recess is arranged axially opposite the first recess 105 and is identical to the first recess 105. The recesses 105, 110, 111 are penetrated in the axial direction by a roller 115.The recesses 105, 110, 111 each have a recess contour 120, 125, 126, wherein the first pendulum track 100 is defined by a circumferential surface of the first roller 115 resting against the respective recess contour 120, 125, 126.
[0028] The centrifugal pendulum device 10 further comprises a second pendulum mass unit 130. The second pendulum mass unit 130 is arranged at least partially axially between the second pendulum flange 25 and the third pendulum flange 30. In the embodiment, the second pendulum mass unit 130 is identical to the first pendulum mass unit 80. Of course, it is also conceivable for the second pendulum mass unit 135 to be different from the first pendulum mass unit 80.
[0029] The second pendulum mass unit 130 has a third pendulum mass 135 and a fourth pendulum mass 140. The fourth pendulum mass 140 is arranged circumferentially adjacent to the third pendulum mass 135. The third and fourth pendulum masses 135, 140 are partially annular in shape.
[0030] The second pendulum mass unit 130 is coupled to the second and third pendulum flanges 25, 30 by means of a second guide rail 145. Of course, it is also conceivable that the second pendulum mass unit 130 is coupled exclusively to the third pendulum flange 30 or exclusively to the second pendulum flange 25 with limited movement via the second guide rail 145.
[0031] In this embodiment, the second guide rail 145 is configured identically to the first guide rail 95. However, in this embodiment, the second guide rail 145 is arranged offset in the circumferential direction relative to the first guide rail 95. Of course, it would also be conceivable for the second guide rail to be arranged offset in the radial direction relative to the first guide rail 95, additionally or alternatively.
[0032] The second link guide 145 has a fourth recess 150 with a fourth recess contour 155 in the second pendulum flange 25. In the third and fourth pendulum masses 135, 140, the second link guide has a fifth recess 160 with a fifth recess contour 165. In the third pendulum flange 30, the second link guide 145 has a sixth recess 170 with a sixth recess contour 175. The fourth recess 150 and the sixth recess 170 are kidney-shaped and have a center of curvature that is arranged radially inward of the fourth and sixth recesses 150, 170, respectively. The fifth recess 160 is also kidney-shaped and has a center of curvature that is arranged radially outward of the fifth recess 160.
[0033] In order to reliably guide the third and fourth pendulum masses 135, 140 in the radial direction along the pendulum track 185, two fifth recesses 160 are provided in the third and fourth pendulum masses 135, 140, respectively. Of course, it is also conceivable that a different number of fifth recesses 160 are provided in the third and fourth pendulum masses 135, 140, respectively.
[0034] A second roller 180 of the second guide rail extends through the fourth, fifth, and sixth recesses 150, 160, 170, which in the embodiment are identical to the first roller 115
[0035] When the centrifugal pendulum is rotating, the roller 180 rests with its circumferential surface against the fourth, fifth, and sixth recess contours 155, 165, 175 and defines a second pendulum track 185. In the exemplary embodiment, the second pendulum track 185 can be identical to the first pendulum track 100. Of course, it is also conceivable for the second pendulum track 185 to be designed differently than the first pendulum track 100. If rotational irregularity is introduced into the pendulum flange 20, 25, 30, the pendulum mass units 80, 130 are excited to oscillate along their pendulum tracks 100, 185, thereby serving as energy storage devices.
[0036] By arranging the third and fourth recesses 111, 150 in the second pendulum flange 25, the axial design of the centrifugal pendulum device 10 can be kept particularly small. It is particularly advantageous if the first pendulum mass unit 80 is arranged offset in the circumferential direction relative to the second pendulum mass unit 130, so that the third recess 111 is arranged alternately with the fourth recess 150 in the circumferential direction in the second pendulum flange 25.
[0037] The centrifugal pendulum device 10 is particularly suitable for vehicles having a reciprocating piston engine with cylinder deactivation. Typically, the number of operating cylinders is halved during cylinder deactivation. For example, in an eight-cylinder engine with two cylinder banks, one of the two cylinder banks is deactivated, so that during operation with cylinder deactivation, four cylinders are supplied with fuel, while the other four cylinders continue to run without being supplied with fuel. The same also applies, for example, to reciprocating piston engines with six cylinders, in which three cylinders are deactivated and the reciprocating piston engine operates with three cylinders during operation with cylinder deactivation.This can also be applied to a different number of cylinders with reciprocating piston engines, for example, in a four-cylinder engine, two cylinders are deactivated and two cylinders are supplied with fuel during cylinder deactivation operation.
[0038] Reciprocating piston engines with cylinder deactivation have two different main excitation orders. The main excitation order depends on the number of cylinders in operation. The main excitation order is usually the order corresponding to half the number of cylinders. For example, the main excitation order of an eight-cylinder engine operating without cylinder deactivation is four, whereas the main excitation order of an eight-cylinder engine with four deactivated cylinders is two.
[0039] When operated with cylinder deactivation, the reciprocating engine runs less smoothly, meaning that rotational irregularities in the torque provided by the reciprocating engine have a higher amplitude than when operated without cylinder deactivation. The high rotational irregularities introduced into the drive train can push conventional centrifugal pendulum mounts to their limits of vibration isolation, causing the pendulum mass units to strike at the end of the pendulum track. This leads to noise emissions.
[0040] In the embodiment, the first pendulum mass unit 80, with its first guide rail 95, is tuned to a first main excitation order of the reciprocating piston engine, for example, during operation of the reciprocating piston engine without cylinder deactivation. Tuning is understood to mean adapting a first damper order of the first pendulum mass unit 80 to the first main excitation order of the reciprocating piston engine in order to achieve the best possible damping of the first main excitation order.
[0041] The second pendulum mass unit 130, with its second guide rail 145, is adapted to a second main excitation order of the reciprocating piston engine, for example, when the reciprocating piston engine is operating with cylinder deactivation. This means that the second damper order of the second pendulum mass unit 130 corresponds to the second main excitation order.
[0042] In the embodiment, the first pendulum mass 85 and the second pendulum mass 90 are guided along the first pendulum track 100, so that the first pendulum mass 85 and the second pendulum mass 90 have the same damping order. The same applies to the third pendulum mass 135 and the fourth pendulum mass 140. The third pendulum mass 135 and the fourth pendulum mass 140 are identical to one another and are guided along the second pendulum track 185, so that the third pendulum mass 135 and the fourth pendulum mass 140 have the second damping order. The variation in the damping orders of the centrifugal pendulum device 10 can be achieved, for example, by having one mass of the pendulum masses 85, 90, 135, 140 identical to one another, but the pendulum tracks 100, 185 being designed differently.It is also conceivable that while the pendulum trajectory 100, 185 of the two pendulum mass units 80, 130 is identical, a mass of the first pendulum mass 85 and / or the second pendulum mass 90 differs from a mass of the third pendulum mass 135 and / or the fourth pendulum mass 140. A combination of the above is also conceivable in order to tune the pendulum mass units 80, 130 in their respective damper order to a main excitation order that differs from the other main excitation order.
[0043] Of course, it is also conceivable for the first damper order to be identical to the second damper order. It is advantageous if the first pendulum mass unit 80 is matched to the first damper order and the second pendulum mass unit 130 is matched to the second damper order.
[0044] It is also conceivable that within the pendulum mass unit 80, 130, one of the pendulum masses 85, 90, 135, 140 is tuned to the first damper order and the other pendulum mass 85, 90, 135, 140 is tuned to the second damper order, so that each of the pendulum mass units 80, 130 is tuned to two different damper orders.
[0045] Fig. 4 shows a modification of the Fig. 1 to 3. The centrifugal pendulum device 10 is similar in its construction to the one shown in the Fig. 1 to 3. In addition, however, a fourth pendulum flange 200 is provided, which is arranged at an axial distance from the third pendulum flange 30. A third pendulum mass unit 205 is partially arranged axially between the third pendulum flange 30 and the fourth pendulum flange 200 and is coupled to the fourth pendulum flange 200 and the third pendulum flange 30 with limited movement by means of a third guide rail (not shown). In the embodiment, the third pendulum mass unit 205 and the third guide rail are identical to the first pendulum mass unit 80 and the first guide rail 95. It is particularly advantageous if the first and third pendulum mass units 80, 205 are matched to a first damper order for damping torsional vibrations of the first main excitation order of the reciprocating piston engine during operation of the reciprocating piston engine with cylinder deactivation.This allows particularly strong rotational irregularities in the torque provided by the reciprocating engine to be eliminated.
[0046] The cascaded arrangement of the pendulum mass units 80, 130, and 205 allows the centrifugal pendulum device 10 to be particularly easily adapted to strong rotational irregularities in the torque provided by the reciprocating piston engine. The pendulum flanges 25, 30 arranged between the pendulum mass units 80, 130, and 205 each guide the pendulum mass unit 80, 130, and 205 arranged on either side of the respective pendulum flange 25, 30, so that, in principle, the number of pendulum flanges 80, 130, and 205 is 1 greater than the number of pendulum mass units 80, 130, and 205 (n(pendulum flange 20, 25, 30, and 205) = n(pendulum mass unit 80, 130, and 205) + 1).
[0047] Fig. Figure 5 shows a cross section through the Fig. 1 to 3 shown embodiment of the centrifugal pendulum device 10 in a further development in a first operating state and Fig. 6 in a second operating state.
[0048] The first pendulum mass 85 is coupled to the second pendulum mass 90 by means of a coupling means 300. For this purpose, the coupling means 300 comprises a first receptacle 305 arranged in the first pendulum mass 85 and a second receptacle 310 arranged in the second pendulum mass 90. The two receptacles 305, 310 extend substantially in the circumferential direction and are arranged on radially extending side surfaces 315, 320 of the respective pendulum mass 85, 90.
[0049] The coupling means 300 further comprises a spring element 325, which in this embodiment is designed as a helical spring. A first end 330 of the spring element 325 is arranged in the first receptacle 305, and a second longitudinal end 335 of the spring element 325 is arranged in the second receptacle 310. The spring element 325 couples the two pendulum masses 85, 90 to one another. If the two pendulum masses 85, 90 are excited to oscillate along the first pendulum track 100 due to a rotational irregularity in the torque, the spring element 325 couples the two pendulum masses 85, 90, so that the first damper order of the first pendulum mass unit 80 can be easily adjusted using the coupling means 300.
[0050] Furthermore, the spring element 325 prevents the two pendulum masses 85, 90 from striking the respective side surfaces 315, 320 by, as in Fig. 6, in the second operating state the spring element 325 is compressed and thereby separates the two pendulum masses 85, 90 from each other.
[0051] The coupling means 300 can of course also be used to couple the third pendulum mass 135 to the fourth pendulum mass 140.
[0052] Fig. Figure 7 shows a section of a longitudinal section through a further development of the Fig. 1 to 6. The centrifugal pendulum device 10 has, in addition to the Fig. 5 and Fig. 6, the first coupling means 300 has a second coupling means 400. The second coupling means 400 comprises a second spring element 415, which is designed as a helical spring. The first pendulum mass unit 80 has a first receptacle 405 on an end face facing the second pendulum mass unit 130. The second pendulum mass unit 130 has a second receptacle 410 on an end face facing the first pendulum mass unit 80.
[0053] A second spring element 415 is arranged in the receptacle 410. The longitudinal ends of the spring element 415 each rest against a radially extending side surface 420, 425 of the receptacle 405, 410. If the first pendulum mass unit 80 is excited to oscillate along the first pendulum track 100 due to a rotational irregularity, the second coupling means 400 transfers the pendulum motion to the second pendulum mass unit 130 and similarly excites it to oscillate along the second pendulum track 185. The second coupling means 400 also allows the respective damper order of the first or second pendulum mass unit / device 80, 130 to be easily adjusted.
[0054] The first pendulum mass unit 80 and the second pendulum mass unit 130 are arranged on a circle and thus on the same diameter relative to the rotation axis 15. Of course, it is also conceivable for the first pendulum mass unit 80 and the second pendulum mass unit 130 to be arranged on different circles relative to the rotation axis 15, each with a different diameter relative to the rotation axis 15. It is also conceivable to dispense with one of the two coupling means 300, 400 or even with both coupling devices 300, 400.
[0055] Furthermore, it is pointed out that the Fig. 1 to 7 shown features individually or together with the other features shown in the Fig. The features shown in 1 to 7 can be combined.
