[0006] Unless otherwise stated or not otherwise apparent from the context, the statements "axially", "radially" and "in the circumferential direction" relate to the direction of extension of the axis of rotation of the centrifugal pendulum device.

At least one pendulum mass, at least one pendulum mass component, the first pendulum mass component, the second pendulum mass component or the intermediate component can have at least one first molded section. The second molded section can be arranged at at least one damping element. At least one damping element can have at least one second molded section for at least one additional connection. At least one additional connection can be engageable and / or disengageable in the axial direction.

[0017] The centrifugal pendulum device may have a main connection portion associated with a radially inner edge segment and / or an edge segment oriented in the circumferential direction of at least one pendulum mass, at least one pendulum mass component, a first pendulum mass component, a second pendulum mass component or an intermediate component. At least one additional connection portion may be arranged between the main connections in the circumferential direction. At least one additional connection portion may be arranged between a main connection portion associated with an edge segment oriented in the circumferential direction of at least one pendulum mass, at least one pendulum mass component, a first pendulum mass component, a second pendulum mass component or an intermediate component and a main connection portion associated with a radially inner edge segment of at least one pendulum mass, at least one pendulum mass component, a first pendulum mass component, a second pendulum mass component or an intermediate component. The centrifugal pendulum device may have a plurality of additional connections. The centrifugal pendulum device may have one additional connection portion or a plurality of additional connections between two main connections.

[0018] At least one pendulum mass, a first pendulum mass component, a second pendulum mass component and / or an intermediate component may have at least one first molded section for at least one additional connection. At least one first molded section may be required for manufacturing at least one pendulum mass, a first pendulum mass component, a second pendulum mass component and / or an intermediate component. At least one first molded section may be a molded section that already exists, exists anyway and / or does not need to be manufactured intentionally at at least one pendulum mass, at the first pendulum mass component, at the second pendulum mass component and / or at the intermediate component due to manufacturing. At least one first molded section may be multifunctional, in particular bifunctional.

[0022] The torque transmission device can be designed for arrangement in a powertrain of a motor vehicle. The torque transmission device can be a shaft, in particular a motor shaft or a crankshaft, a torsional vibration damper, in particular a dual mass flywheel, a friction clutch device, a hydrodynamic converter, a transmission and / or an auxiliary unit drive.

[0023] In summary and in other words, the present invention can therefore also provide an additional rubber support at the intermediate part. The area between the main connections at the intermediate part can be used in order to additionally support the damping element there in the circumferential direction. The intermediate part can have a so-called attachment area in the area between the main connections. The attachment area can be caused by manufacturing and is important for the stamping process (attachment to the strip). The attachment area can be structurally modified so that it not only fulfills the function for manufacturing the intermediate part, but is also suitable as an additional contact surface or additional connection for supporting the damping element in the circumferential direction. The contour of the damping element can be provided with additional molded sections, in particular cams, which can then assume additional form fit at the attachment area of ​​the intermediate part.

[0024] Furthermore, it is also possible to derive an intermediate component which does not have such an attachment area between the main connections. The intermediate component can then have an alternative attachment area. In the case of the intermediate component, the area between the main connections can also be used in order to ensure additional support for the damping element in the circumferential direction. The possible shapes in the case of such a support or additional connection can then be very diverse, for example a jigsaw puzzle hang or any other shape suitable for supporting the damping element in the circumferential direction. The number of additional connections can also vary.

[0025] The invention reduces the relative movement between at least one pendulum mass component, the first pendulum mass component, the second pendulum mass component or the intermediate component on the one hand and at least one damping element on the other hand. The loads, in particular the compressive and shear stresses, of the at least one damping element are reduced. The wear and / or maintenance requirements are reduced.

[0032] The same reference numerals are used for elements and structures having the same function and / or being of the same type.

[0033] Figure 1 A part of a centrifugal pendulum device 100 according to a first embodiment of the present invention is shown. The centrifugal pendulum device 100 is arranged on a torsional vibration damper (not shown) which is implemented as a dual mass flywheel and is arranged in a powertrain of a motor vehicle driven by an internal combustion engine. The centrifugal pendulum device 100 includes a pendulum mass carrier 102 and a pendulum mass such as 130 which can rotate around a rotation axis. Each pendulum mass 130 has two pendulum mass parts (not shown) of the same size and axially spaced apart, which are rigidly connected to each other via an intermediate part 132 and are arranged movably on the pendulum mass carrier 102 laterally opposite to each other. The intermediate part 132 is inserted into a recess 104 of the pendulum mass carrier 102 with clearance. The pendulum mass parts and the intermediate part 132 are riveted to each other. The pendulum mass 130 is arranged on the pendulum mass carrier 102 by means of rolling bodies such as 108, and can be moved into an operating position under the action of centrifugal force and can be moved along a pendulum track under the action of torsional vibration in the operating position to eliminate torsional vibration.

[0034] The recess 104 has an inner contour 120. The inner contour is used to limit the movability of the pendulum mass 130 together with the elastic damping element 134. The damping element 134 radially surrounds the middle part 132 on the inside. The damping element 134 is supported at the outer contour 122 of the middle part 132. The damping element 134 is fixed to the middle part 132 via a main connection, which is formed by means of a first protrusion 116 and a first recess 118. The protrusion 116 is locked in a radial direction and in a circumferential direction into a corresponding first recess 118 of the middle part 132 in a form-fitting manner. The first recess 118 is formed by means of a section of the outer contour 122. The first protrusion 116 is here respectively connected to an end area 154 (see FIG. 1 ) of the middle part 132 oriented in the circumferential direction. Figure 3 ). The other first protrusion 116 is arranged centrally on the middle part 132 in the circumferential direction. The first protrusions 116 are formed in the same shape and size. The first protrusions imitate the cross section of a mushroom, that is, they are formed in a mushroom shape. The mushroom shape is characterized by a trunk section 151, which is thinner than the head section 152 (see for details). Figure 3 ). In this case, the axially outer end region of the mushroom shape is flattened, ie extends largely perpendicularly to the axis of rotation.

[0035] There is an additional connection formed by means of second projections 136 and second recesses 138. The second projections 136 are positively locked in the radial direction and in the circumferential direction in the corresponding second recesses 138 of the intermediate part 132. The second recesses 138 are also formed by means of sections of the outer contour 122.

[0036] The additional connection is designed to reduce compressive and / or shearing stresses acting on or in the damping element 134 during operation, in particular due to normal forces F acting in the radial direction. N and the friction coefficient μ acting in the circumferential direction 1 , μ 2 The friction force F R1 、F R2 cause.

[0037] Figure 2 A pendulum mass 130 is shown, which has a middle part 132 together with a damping element 134 according to a first embodiment in the installed state. Figure 1 Details not yet described. For a general overview, therefore refer to Figure 1 . The pendulum mass components are not shown in order to better illustrate the middle part 132 together with the damping element 134. The damping element 134 is designed here with a U-shaped cross section. According to a first embodiment of the U-shaped damping element 134, two second protrusions 136 are provided between every two first protrusions 116. The two second protrusions are axially introduced into corresponding second recesses 138 in order to abut against the middle part 132 in a form-fitting manner in the radial direction and in the circumferential direction. The second recess 138 already exists here as a result of manufacturing, i.e. it is not first formed and introduced into the middle part 132 in order to assume the corresponding function as the second recess 138. More precisely, the recess 138 exists because it has already been manufactured and is used for an additional connection and is therefore functionally replanned. The second recess 138 here, as in Figure 3 Correspondingly, the second projection 136 is configured in an arc shape here according to the first embodiment.

[0038] Figure 3 The intermediate part 132 is shown together with the damping element 134 according to the first embodiment in a disassembled state. Figure 3 1, the first projection 116 is designed to engage in the first recess 118. Here, the first projection 116 and the corresponding first recess 118 are also designed to be locked in the damping element 134 by means of the first recess 118. As a result, the damping element 134 is locked with the middle part 132 in a form-fitting manner. In the locked state, the damping element 134 is locked at the middle part 132, as in Figure 2 The mushroom shape described in detail with a trunk section 151 and a head section 152 is used for this. The wide head section 152 forms an undercut. For the installed state, as it is in Figure 2 As shown in FIG. 1 , the damping element-side contact surface 150 and the intermediate-piece-side contact surface 153 of the first recess 118 and the second recess 138 are in positive contact with each other.

[0039] The second protrusion 136 is, in contrast, arc-shaped in the first embodiment. Thus, although the second protrusion does not have a locking function like the first protrusion 116, it nevertheless absorbs frictional forces and normal forces, as shown in the reference Figure 1 As shown and described, and it is guided further into the intermediate part 132. The deformation of the elastic damping element 134, as it refers to Figure 1 As described in detail, this is also limited by the second projection 116. A tearing off of the material of the damping element 134 is counteracted.

[0040] The second recess 138 has an edge 142. In addition, the second recess 138 has a smooth contour stretch 143. Here, two edges 142 of adjacent second recesses 138 are arranged closer to each other than the corresponding smooth contour stretch 143. In the region of the edge 142, the damping element 134 has a recess 146 which is designed as a channel-shaped recess. The recess 146 is designed so that even when the damping element 134 is deformed at a block angle, direct contact between the damping element 134 and the intermediate part 132 in the region of the edge 142 is avoided.

[0041] Figure 4 The pendulum mass 200 is shown, which has an intermediate part 202 together with a damping element 204 according to a second embodiment in the installed state. In this case, the second protrusion 206 is arranged in a corresponding recess 208. The second protrusion 206 is formed in the same shape as the first protrusion 116 in the shape of a mushroom with a trunk section 151 and a head section 152. The trunk section 151 transitions into the remaining body of the damping element 204 in the region of the first contact line 210 and the second contact line 212. From the first contact line 210 and from the second contact line 212, the second protrusion 206 protrudes from the base body of the damping rail 204. However, the second protrusion 206 is formed in a different size from the first flange 116. In this case, the second protrusion 206 is smaller than the first protrusion 116.

[0042] Figure 5A pendulum mass 300 is shown, which has an intermediate part 302 together with a damping element 304 according to a third embodiment in the installed state. In this case, a second protrusion 306 is arranged in a corresponding recess 308. The second recess 306 is neither identical in shape nor in size to the first recess 116. The second recess 306 is configured in a nose-shaped or drop-shaped shape. In this case, a head section 313 is configured, which has a circular outer contour, which is placed on a trunk section 314. The trunk section 314 transitions into the remaining body of the damping element 304 in the region of a first contact line 310 and a second contact line 312. From the first contact line 310 and from the second contact line 312, the second protrusion protrudes from the base body of the damping element 304. In this case, the second protrusion 306 is smaller than the first protrusion 116 both in terms of the volume encompassed by the second protrusion 306 and in terms of the axial cross section.

[0043] The term “may” in particular refers to optional features of the invention. Therefore, there are also refinements and / or embodiments of the invention which additionally or alternatively have one or more corresponding features.

[0044] Individual features may also be selected from the presently disclosed combination of features as required and used to define the subject matter of the claim in combination with other features without any structural and / or functional relationships between the features that may exist.
