Description

Torsional vibration damper
Technical Field
The invention relates to a torsional vibration damper, in particular for motor vehicles.
Background
Various torsional vibration dampers of different designs are known from the prior art, in particular for drive trains of motor vehicles. These torsional vibration dampers have, for example, spring damping means and optionally centrifugal pendulum means for damping torsional irregularities of the torque to be transmitted. These torsional vibration dampers are known, for example, as dual mass flywheel, clutch damper, dual clutch damper. Here, the input member and other members as a sub-assembly structure are connected to each other and then also machined, for example, to form a crankshaft mating portion. The plastic components are also integrated into the sub-assembly, whereby the machined chips and coolant and lubricant must be cleaned after machining, which increases the production costs.
Disclosure of Invention
The object of the present invention is to provide a torsional vibration damper which is improved over the prior art, so that the costs of the manufacturing process are reduced.
The object with respect to a torsional vibration damper is achieved by the features of claim 1.
An embodiment of the invention relates to a torsional vibration damper having an input part and having an output part, wherein the input part can be arranged in a rotatable manner relative to the output part against a restoring force of a damping device, wherein the input part has at least one primary-side disk, wherein a further disk is provided, which is connected to the primary-side disk in a riveted manner, wherein the primary-side disk and the further disk are connected to one another in a sub-assembly and jointly are machined by cutting, wherein a ring is provided, which is connected in a form-locking manner to a subassembly consisting of the primary-side disk and the further disk, wherein the further disk radially centers the ring, wherein the damping device has an input element and an output element, wherein the output element and/or an element connected to the output element fixes the ring in position axially. This results in a sub-assembly and by a cutting process, wherein the arrangement of the ring and the further assembly is performed after the cutting process. This eliminates laborious cleaning of the ring, which saves costs.
It is also advantageous if the ring element serves as an axial bearing for the output element and/or the element connected to the output element. The ring can thereby be supported axially on the input part on the one hand and serve on the other hand as an abutment surface for the output element and/or the element connected thereto. The ring is preferably constructed as a plastic ring.
It is also advantageous if the output element of the damping device is a flange element, in particular of a spring damping device. A targeted abutment and axial support of the output element or of an element connected to the output element is thus achieved.
It is also advantageous if an axially elastic diaphragm element is provided, which on one side axially bears against the output element and on the other side bears against an element connected to the input part, in order to cause an axial force loading of the output element on the ring. This enables a targeted abutment on the ring, which at the same time means that the ring bears in a defined manner against the input part, so that a loss-proof fastening of the ring is possible.
In one embodiment, it is also advantageous if the sub-assembly of riveted primary-side disks and further disks, optionally with at least one further component, is formed radially inside by cutting, in particular by milling, with a fitting, in particular a crankshaft fitting. Exemplary mating portions of the sub-assembly structure can thereby be manufactured, as can pre-assembled sub-assembly structures that later need to be assembled, whereby the mating portions can be manufactured in one step.
It is also expedient if the further disk element is designed as a support disk and has a ring region extending in the axial direction on the radially inner side. The support plate can be formed as a sheet metal plate for supporting the ring element and for example also for bearing against a screw for screwing the torsional vibration damper.
In a further embodiment, it is expedient if the further disk element, for example the support disk, has a radially outer annular region with an L-shaped cross section, which has a first annular region extending in the axial direction and a second annular region extending in the radial direction. Two radially outer ring areas are provided for receiving the ring elements and fixing their position.
In a further embodiment, the second ring region expediently has circumferentially extending recesses or circumferentially extending teeth. A reliable arrangement of the ring is thereby achieved with simple installation.
It is also advantageous if the ring has a recess or a tooth extending in the circumferential direction on the radially inner side, wherein the recess and/or the tooth of the ring corresponds to a recess or a tooth of the second ring region of the further disk. This enables a reliable form-locking connection.
It is also expedient for the primary side disk element and the further disk element of the sub-assembly structure each to have aligned threaded bores for the bolts to pass through, so that the torsional vibration damper is screwed.

An axially elastic diaphragm element 13 is also provided, which on one side bears radially inwardly against the output element, which is formed here as a flange part 7, and on the other side bears radially outwardly against the element connected to the input part 2, here the secondary-side disk part 6, in order to bring about an axial force loading of the output element on the ring part 12. Alternatively, the diaphragm element 13 is supported on the secondary-side disk 6 with the ring 14 interposed.
The other disk element 10 serves as a support disk and has a radially inner ring region 15 extending in the axial direction. The ring region is preferably machined together with the primary-side disk 5 in the sub-assembly.
Optionally, the further disk element 10 has a radially outer ring region 16 with an L-shaped cross section, which has a first ring region 17 extending in the axial direction and a second ring region 18 extending in the radial direction.
