Description

Technical Field

[0001] The present application relates to a centrifugal pendulum, and also relates to a torque transmission device including the centrifugal pendulum and a vehicle including the torque transmission device. Background Art

[0002] In a power transmission system of a vehicle, a shock absorber is usually provided between an internal combustion engine and a transmission to eliminate torsional vibrations inherent in the output of the internal combustion engine. A centrifugal pendulum is a common torsional vibration shock absorber, which includes a support disk and a mass block mounted on the support disk. When torsional fluctuations occur on the support disk, the mass block can swing relative to the support disk in a restricted manner and apply a fluctuating torque in the opposite direction on the support disk, achieving a shock absorption effect.

[0003] A conventional centrifugal pendulum includes two mass blocks located on both sides of the support disk, and the two mass blocks are fixed to each other by means of a connecting member. The connecting member passes through a through hole located on the support disk. In order to restrict the movement of the mass block along a predetermined trajectory, it is necessary to form a track surface with a specific profile on the connecting member and the through hole. In a centrifugal pendulum with this structure, the mass blocks protrude from both sides of the support disk, so special attention needs to be paid to the arrangement and dimensions of the components on both sides of the centrifugal pendulum to avoid interfering with the rotation of the mass blocks; moreover, this centrifugal pendulum requires a separate connecting member, and the number of parts is large, resulting in more complex processing and assembly.

[0004] Therefore, it is desirable to provide a centrifugal pendulum with an improved structure to at least overcome many problems existing in the prior art. Summary of the Invention

[0005] An object of the present invention is to simplify the structure and assembly of the centrifugal pendulum.

[0006] In one aspect of the present invention, a centrifugal pendulum is provided, which includes a first support disk capable of rotating around a rotation axis; a second support disk facing the first support disk in the axial direction and fixed to the first support disk; and a mass block disposed between the first support disk and the second support disk in the axial direction. The first support disk has an axially extending first protrusion, which is integrally formed with the first support disk and defines a first track; the mass block has an axially extending through hole, which defines a second track; and the first protrusion extends into the through hole such that the first track and the second track are opposite to each other in the radial direction. A roller is disposed between the first track and the second track in the radial direction and can roll against the first track and the second track, such that the mass block can swing relative to the first support disk and the second support disk in a plane perpendicular to the rotation axis, and apply a torque on the first support disk and the second support disk. This torque can cancel the torque vibration transmitted to the centrifugal pendulum.

[0007] According to this technical solution, it is defined that the first protrusion of the first track is integrally formed with the first support disk, eliminating the need for separately machining and assembling components specifically for defining the first track. This reduces the number of components and simplifies the structure and assembly of the centrifugal pendulum. Moreover, the mass block is located between the two support disks, preventing the mass block from being exposed outside the centrifugal pendulum and avoiding interference between the mass block and external components.

[0008] In some embodiments, the first support disk has a first recess that is axially recessed, and the first recess is provided on the outer surface of the first support disk opposite to the first protrusion.

[0009] In some embodiments, the first support disk can be formed by stamping, simultaneously forming the first protrusion and the first recess. In this case, the protrusion and the recess can be integrally formed on the support disk through a simple stamping step, which simplifies the manufacturing of the support disk.

[0010] In some embodiments, the second support disk has a second protrusion that extends axially towards the first protrusion. The second protrusion is integrally formed with the second support disk, and the second protrusion extends into the through hole. The first protrusion and the second protrusion together define the first track. The first protrusion and the second protrusion can have the same protrusion height to each form half of the first track. In other embodiments, the first protrusion and the second protrusion can have different protrusion heights.

[0011] In some embodiments, the first support disk and the second support disk are fixed to each other at the first protrusion through a coupling member. In this case, the coupling member can be at least partially received in the first recess corresponding to the first protrusion, thereby reducing the axial dimension of the centrifugal pendulum. The coupling member can be a rivet, a screw, a welded part, etc.

[0012] In some embodiments, the second support disk has a second recess that is axially recessed, and the second recess is provided on the outer surface of the second support disk opposite to the second protrusion. The first end of the coupling member can be received in the first recess and does not extend beyond the outer surface of the first support disk, and the opposite second end of the coupling member can be received in the second recess and does not extend beyond the outer surface of the second support disk. In this case, the outer surfaces of the first support disk and the second support disk are both flush without any protruding parts, which can reduce the axial dimension of the centrifugal pendulum and avoid interference with other adjacent components.

[0013] In some embodiments, the first track has a first concave surface, and the second track has a second concave surface. The first concave surface and the second concave surface face each other, forming a shape similar to an eye. The roller is located between the first concave surface and the second concave surface and can roll while abutting against the surfaces of the first concave surface and the second concave surface. Thus, the mass block can swing relative to the first and second support disks in a circumferential distance approximately equal to the sum of the circumferential widths of the first concave surface and the second concave surface.

[0014] In some embodiments, the first track may be located radially inside the first protrusion, and the second track may be located radially inside the through hole.

[0015] In some embodiments, the first track may be located radially outside the first protrusion, and the second track may be located radially outside the through hole.

[0016] In some embodiments, the first support disk has an axially extending third protrusion that is integrally formed with the first support disk and defines a third track. The mass has another axially extending through hole that is circumferentially offset from the through hole by an angle, and this another through hole defines a fourth track. The third protrusion extends into the another through hole such that the third track and the fourth track are opposite in the radial direction. Also, another roller is disposed radially between the third track and the fourth track and can roll against the third track and the fourth track, such that the mass can move relative to the first support disk and the second support disk and apply a torque to the first support disk and the second support disk.

[0017] In this case, the first sliding arrangement composed of the first track, the second track, and the roller and the second sliding arrangement composed of the third track, the fourth track, and the another roller may be the same and offset from each other by a certain angle about the axis of rotation. Thus, the mass can swing more smoothly relative to the first and second support disks.

[0018] In another aspect of the present invention, a torque transmission device is provided, including a centrifugal pendulum as described above. This centrifugal pendulum can reduce torque vibration in the torque transmission device and has a compact structure and simplified assembly.

[0019] In some embodiments, the torque transmission device may be a torque converter, a clutch device, or a dual mass flywheel.

[0020] In still another aspect of the present invention, a vehicle is provided, including the torque transmission device as described above. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The following describes in detail the specific embodiments of the present invention with reference to the accompanying drawings. Components with the same or similar reference numerals in the drawings have the same or similar functions.

[0028] In the following description, the "axial direction" refers to the direction parallel to the rotation axis X of the centrifugal pendulum P; the "circumferential direction" refers to the circumferential direction around the rotation axis X; the "radial direction" refers to the direction perpendicular to the rotation axis X, where "outward", "outer side", etc. refer to the direction radially outward away from the rotation axis X, and "inward", "inner side" refer to the direction radially inward close to the rotation axis X.

[0029] As Figure 1 shown, the centrifugal pendulum P according to the present invention includes a first support disk 1 and a second support disk 2, which are opposite to each other in the axial direction and fixed to each other. The mass block 3 is arranged between the first support disk 1 and the second support disk 2 in the axial direction.

[0030] The two first support disks 1 and the second support disk 2 may have a disk shape, having the same diameter and overlapping. Through holes are provided at the centers of the first support disk 1 and the second support disk 2 for assembling a rotating shaft. The rotating shaft receives torque from an internal combustion engine and drives the first support disk 1 and the second support disk 2 to rotate around the rotation axis X passing through the center.

[0031] In other embodiments, the first support disk 1 and the second support disk 2 may have other suitable shapes (e.g., annular). Additionally, the first support disk 1 and the second support disk 2 may be coupled (e.g., riveted) to a rotating disk body of an existing device (e.g., the turbine disk of a torque converter).

[0032] Two sets of mass blocks 3 may be arranged between the first support disk 1 and the second support disk 2, the two sets of mass blocks 3 being arranged near the circumferential edges of the first support disk 1 and the second support disk 2 and being symmetric about the rotation axis X. In other embodiments, other numbers of multiple sets of mass blocks may be provided, such as three sets, four sets, etc., the multiple sets of mass blocks being uniformly arranged around the rotation axis X. Each set of mass blocks 3 may have a sector-annular shape, i.e., having an inner arc edge extending at an angle and an outer arc edge extending at the same angle. In other embodiments, mass blocks of other shapes may be provided.

[0033] Figure 2The structure of the first support disk 1, the second support disk 2, and the mass block 3 is shown.

[0034] The first support disk 1 has a first protrusion 11 extending axially, and the first protrusion 11 is integrally formed with the first support disk 1. The second support disk 2 has a second protrusion 21 extending axially toward the first protrusion 11, and the second protrusion 21 is integrally formed with the second support disk 2. The first protrusion 11 and the second protrusion 21 together define a first track R1. The mass block 3 has a through hole 31 extending axially, and the through hole 31 defines a second track R2. Both the first protrusion 11 and the second protrusion 12 extend into the through hole 31, such that the first track R1 and the second track R2 are opposite in the radial direction.

[0035] The roller 5 is disposed between the first track R1 and the second track R2 in the radial direction and can roll against the first track R1 and the second track R2, such that the mass block 3 can swing relative to the first support disk 1 and the second support disk 2 within a circumferential distance. During the swinging, the mass block 3 applies a torque on the first support disk 1 and the second support disk 2 via the roller 5 to counteract the torque fluctuations on the first support disk 1 and the second support disk 2.

[0036] In particular, the support disks 1 and 2 of the present invention are each formed by stamping, so as to integrally form the first protrusion 11 and the second protrusion 12 thereon. Taking the first support disk 1 as an example, during the stamping process, a part of the material of the first support disk 1 advances a certain distance toward the side of the mass block 3 while remaining firmly connected to the remaining material of the support disk 1. Thus, a first protrusion 11 with a certain circumferential height is formed on the inner surface of the support disk 1; correspondingly, a first depression 12 with a certain circumferential depth is formed on the outer surface of the first support disk 1 and on the back of the first protrusion 11.

[0037] The assembly operation of the centrifugal pendulum P is as follows:

[0038] - First, align the two support disks 1 and 2 and the mass block 3 such that both the first protrusion 11 and the second protrusion 21 are aligned with the corresponding through holes 31, and place the roller 5 between the first track R1 on the first protrusion 11 and the second track R2 on the through hole 31 of the second protrusion 21, as Figure 2 shown;

[0039] - Then, axially push the two support disks 1 and 2 so that the first protrusion 11 and the second protrusion 21 extend into the interior of the through hole 31 and contact each other, such that the inner and outer edges of the roller 5 respectively contact the first track R1 and the second track R2;

[0040] - Then, use the rivet 4 to rivet the two protrusions 11 and 21 together. Thus, the two support disks 1 and 2 are riveted together.

[0041] Since the sum of the heights of the two protrusions 11 and 21 is greater than the depth of the through hole 31 (i.e., the thickness of the mass 3), there is an axial gap between the assembled support disks 1, 2 and the mass 3, allowing the mass 3 to swing relative to the support disks 1, 2 in a plane perpendicular to the rotation axis X.

[0042] According to the present invention, since the support disks 1, 2 and the protrusions 11, 21 thereon are integral, the centrifugal pendulum P of the present invention reduces the number of parts compared to the case of providing the first track R1 with separate parts, thus simplifying the assembly operation.

[0043] In addition, the two ends of the rivet 4 can be respectively received in the first recess 12 and the second recess 22 on the outer surfaces of the two support disks 1, 2, and preferably do not extend beyond the outer surfaces of the support disks 1, 2. In this case, there are no protruding parts on the outer surfaces of the support disks 1, 2, which helps to reduce the axial distance of the centrifugal pendulum 3 and avoid interference with other adjacent components. In other embodiments, other connecting components 4 such as screws and weldments can also be used to fix the two support disks 1, 2, and the connecting components can also protrude beyond the outer surfaces of the support disks 1, 2.

[0044] In Figure 2 In the illustrated embodiment, the first protrusion 11 and the second protrusion 21 have the same height, and each of them defines half of the first track R1. In other embodiments not shown, the heights of the first protrusion 11 and the second protrusion 21 can also be different. Even, the second protrusion 21 may not be formed, and only the first protrusion 11 is used to form the first track R1. At this time, the height of the first protrusion 11 is approximately equal to the depth of the through hole 31, and the first protrusion 11 itself is fixedly connected to the second support disk 2.

[0045] In addition, in order to make the swing of the mass 3 more stable, another through hole 32 can be formed in the mass 3. As Figure 2As shown, the geometric structures of the through holes 31 and 32 are exactly the same and are offset by an angle in the circumferential direction. In this case, the first support disk 1 has an axially extending third protrusion 13, and the third protrusion 13 is integrally formed with the first support disk 1 and defines a third track R1. Another additional through hole 32 defines a fourth track R4. The third protrusion 13 extends into the said another through hole 32 such that the third track R3 and the fourth track R4 are opposite to each other in the radial direction. Also, another roller 6 is disposed radially between the third track R3 and the fourth track R4 and is capable of rolling against the third track R3 and the fourth track R4. In this case, the mass 3 swings relative to the first support disk 1 and the second support disk via the two rollers 5 and 6 simultaneously, and applies torque via the two rollers 5 and 6 simultaneously. Since the two rollers 5 and 6 are arranged one behind the other in the swinging direction, the mass 3 can be urged to rotate more smoothly relative to the rotating disks 1 and 2. In other embodiments, other numbers (for example, three) of through holes may also be provided for each mass 3.

[0046] Regarding the setting manners of the first track R1 and the second track R2, the present invention proposes the following two embodiments.

[0047] First Embodiment

[0048] Figures 1 to 3 The centrifugal force pendulum P according to the first embodiment is shown. As Figure 3 shown, taking the protrusion 11 of the first support disk 1 as an example, each protrusion 11 is formed adjacent to the outer periphery of the first support disk 1, that is, the outer side of each protrusion 11 is part of the outer peripheral edge of the first support disk 1. Additionally, the radially inner side of each protrusion 11 defines a first track R1 having a specific profile for contacting the radially outer side of the roller 5 and guiding the rolling of the roller 5. The inner side and the outer side of each protrusion 11 are connected on both sides by two radial side edges. The protrusions on the first support disk 1 and the second support disk 2 have the same structure.

[0049] As Figure 2 shown, taking the first through hole 31 as an example, the radially outer side of each through hole 31 is arc-shaped for contacting the radially outer sides of the first protrusion 11 and the second protrusion 21 extending into the through hole 31; correspondingly, the outer sides of the first protrusion 11 and the second protrusion 21 can support the mass 3 and guide its swinging in the circumferential direction. The radially inner side of the through hole 31 defines a second track R2 having a specific profile for contacting the radially inner side of the roller 5 and guiding the rolling of the roller 5. The inner side and the outer side of the through hole 31 are connected on both sides by two radial side edges.

[0050] In operation, if the torque on the support disks 1 and 2 fluctuates, through the coordinated action of the rollers 5, the first track R1, and the second track R2, the mass block 3 can swing circumferentially and radially relative to the support disks 1 and 2 along a pre-designed trajectory. During this period, the mass block 3 applies torques in opposite directions on the support disks 1 and 2 via the rollers 5 to counteract the torque fluctuations on the support disks 1 and 2.

[0051] Figure 2 and Figure 3 shows exemplary profiles of the first track R1 and the second track R2. The first track R1 has first and second convex surfaces A that bulge radially inward, and a first concave surface B that is recessed radially outward is defined between the first and second convex surfaces A. The second track R2 has third and fourth convex surfaces C that bulge radially outward, and a second concave surface D that is recessed radially inward is defined between the third and fourth convex surfaces C. The roller 5 is located between the first concave surface B and the second concave surface D. During the swinging of the mass block 3, the roller 5 rolls along the surfaces of the first concave surface B and the second concave surface D, and forces are transmitted along the contact lines of the roller 5 with the first concave surface B and the second concave surface D, generating fluctuating torques in opposite directions.

[0052] In addition, as Figure 2 shown, in the mass block 3, a side concave surface that is recessed radially inward is defined between the third and fourth convex surfaces C and the adjacent sides of the through-hole, which can prevent interference between the first and second convex surfaces A of the first track R1 and the surface of the second track R2 during swinging.

[0053] In some embodiments, damping elements, such as rubber pads, can be provided at the two side positions of the through-hole 31 of the mass block 3 and / or the two side positions of the protrusions 11 and 21 of the support disks 1 and 2 to reduce the impact generated when the mass block 3 contacts the support disks 1 and 2.

[0054] Second Embodiment

[0055] Figures 4 to 6 shows a centrifugal pendulum P' according to the second embodiment. The centrifugal pendulum P' is basically the same as the centrifugal pendulum P of the first embodiment, and only the differences between the two will be described below.

[0056] In the second embodiment, as Figure 6 shown, taking the first protrusion 11' of the first support disk 1' as an example, each protrusion 11' is formed away from the outer periphery of the first support disk 1', that is, the radially outer edge of the protrusion 11' is spaced a certain distance from the outer peripheral edge of the support disk 1'. In addition, the radially outer edge of each protrusion 11' defines a first track R1' with a specific profile for contacting the radially inner side of the roller 5' and guiding the rolling of the roller 5'.

[0057] AsFigure 5 As shown, the radially inner edge of the through hole 31' is arc-shaped for contacting the radially inner edge of the protrusion 11' extending into the through hole 31'; correspondingly, the radially inner edge of the protrusion 11' can support the mass 3' and guide its swing in the circumferential direction. The radially outer edge of the through hole 31' defines a second track R2' with a specific profile for contacting the outer side of the roller 5' and guiding the rolling of the roller 5'.

[0058] During operation, if there are fluctuations in the torque on the support disks 1', 2', through the cooperative action of the roller 5', the first track R1', and the second track R2', the mass 3' can swing circumferentially and radially relative to the support disks 1', 2' along a pre-designed trajectory. During this period, the mass 3' applies torques in opposite directions on the support disks 1', 2' via the roller 5' to offset the torque fluctuations on the support disks 1', 2'.

[0059] Figure 5 and Figure 6 Exemplary profiles of the first track R1' and the second track R2' are shown. The first track R1' has first and second convex surfaces A' protruding radially outward, and a first concave surface B' recessed radially inward is defined between the first and second convex surfaces A'. The second track R2' has third and fourth convex surfaces C' protruding radially inward, and a second concave surface D' recessed radially outward is defined between the third and fourth convex surfaces C'. The roller 5' is located between the first concave surface B' and the second concave surface D'. During the swing of the mass 3', the roller 5' rolls along the surfaces of the first concave surface B' and the second concave surface D' simultaneously, and forces are transmitted along the contact lines between the roller 5' and the first concave surface B' and the second concave surface D' to generate torque fluctuations in opposite directions.

[0060] The torque transmission device according to the present invention includes the above-described centrifugal pendulum. The torque transmission device can be a hydraulic torque converter, a clutch device, or a dual-mass flywheel. The centrifugal pendulum can reduce the torque fluctuations transmitted from an internal combustion engine to the hydraulic torque converter, the clutch device, or the dual-mass flywheel.

[0061] The vehicle according to the present invention includes the above-described torque transmission device. The vehicle is, for example, an automobile, an engineering vehicle, an agricultural vehicle, etc. This torque transmission device can provide a vibration damping effect to eliminate the torque vibration generated by the internal combustion engine of the vehicle. This is beneficial for saving fuel consumption, reducing noise, and improving the reliability of the vehicle, etc.

[0062] Certain preferred embodiments and other embodiments for implementing the present invention have been described in detail above. However, it should be understood that these embodiments are for illustrative purposes only and do not limit the scope, application, or construction of the present invention in any way. The scope of protection of the present invention is defined by the appended claims and their equivalents. Those skilled in the art can make many changes to the foregoing embodiments under the teachings of the present invention, and these changes all fall within the scope of protection of the present invention.
