- the invention further relates to a method for producing a device for damping torsional vibrations in a drive train, comprising the steps
- Known torsional vibration dampers comprise a drive device and an output device, the drive device and output device being arranged rotatably about a common axis.
- a damper tion device the drive device and the output device with each other.
- Drive device and output device are mounted on the common axis both radially and axially by means of an axial bearing device.
- the drive device, the output device and the axial bearing device are arranged with respect to one another in such a way that a partially delimited area is formed in which the damping device is arranged.
- Known damping devices include arc-shaped springs which absorb the torsional vibrations.
- the springs touch the corresponding loading limits in the damping device.
- Corresponding turns of a spring also touch each other, which leads to premature wear and thus failure of the torsional vibration damper.
- a torsional vibration damper which has a drive element and an output element, the drive element and output element being rotatable about a common axis.
- Drive element and output element are further connected to each other via springs arranged in an arc shape for damping torsional vibrations. Furthermore, the springs are provided with a coating that increases wear resistance.
- one of the disadvantages of the known torsional damper devices is that elements in the interior, in particular the springs, are protected against wear, but not against other, external environmental influences.
- An object of the present invention is therefore to provide a device for damping torsional vibrations in a drive train and a method for producing a device for damping torsional vibrations, which provide improved protection against external environmental influences.
- Another object of the present invention is to provide an alternative device for damping torsional vibrations and an alternative method to provide a device for damping torsional vibrations.
- the present invention achieves the above-mentioned objects in a device for damping torsional vibrations in a drive train, comprising a drive device, an output device, the drive device and output device being arranged rotatably about a common axis, a damping device which connects the drive device and output device to one another, an axial bearing device for the axial mounting of drive device and output device, the drive device, a cover device and the axial bearing device being arranged with respect to one another in such a way that a partially delimited spatial area is formed, at least one damping element of the damping device being arranged in the spatial area, thereby that elements of the drive device, cover device, output device and axial bearing device are arranged to prevent liquid entry, in particular water entry, and nd / or are designed to reduce liquid ingress into the room.
- the present invention achieves the above objects in a method for manufacturing a device for damping torsional vibrations in a drive train, comprising the steps
- One of the advantages achieved with this is that improved protection against external environmental influences, in particular penetrating liquids, is made possible. In addition, the life of the device is increased.
- the damping device comprises at least one damping element which is designed to be liquid-repellent.
- the at least one damping element is provided with a liquid-repellent coating and / or with a corrosion protection coating.
- the life of the damping device is further increased while at the same time being simple to manufacture.
- At least one of the devices is acted upon with a lubricant, in particular a grease, which is liquid-repellent, in particular water-repellent.
- a lubricant in particular a grease, which is liquid-repellent, in particular water-repellent.
- At least one element of the drive device, output device and / or cover device which limits the area to the outside, is hole-free and / or provided with at least one hole which is closed.
- the likelihood of liquid being introduced into the room area can be further reduced.
- simple assembly is made possible: for example, assembly holes can continue to be used for assembling the device, since these are subsequently closed after the corresponding assembly of the device, so that the likelihood of liquid entry into the space area is also minimized.
- a spring device which provides a predeterminable axial preload on at least one axial bearing element of the axial bearing device, so that a certain preload force on the latter is not undercut.
- the spring device is arranged on the cover device. This enables a simple and reliable arrangement of the spring device.
- the spring device is arranged between the cover device and the axial position device in such a way that it limits the area to the outside. This enables a simple and at the same time reliable demarcation of the room area from the outside; additional components or components can then be dispensed with.
- the thrust bearing element, with which the spring device interacts is arranged on the radial inside of the spring device. This enables, in particular in the area of the axis of rotation, a minimization of existing or temporarily forming gaps, which further reduces the likelihood of fluid ingress.
- the axial bearing device comprises at least one axial bearing element, in particular a thrust ring, which has a greater extension in the axial direction than an element of the output device adjacent in the radial direction, and the at least one axial bearing element of the axial bearing device bears against an element of the output device direction without axial gaps . Openings or spaces in the space are thus covered by the axial bearing element and the space is protected against the ingress of liquid.
- a spacer element is arranged and formed between an inside of the drive device and an axial bearing element such that the spacer element at least partially encompasses the axial bearing element in the radial and axial directions, in particular with the spacer element being designed as a sheet metal. Another advantage of this is that the likelihood of fluid ingress is further reduced by the axial and radial engagement. If the spacer element is designed as a sheet metal, simple and inexpensive production is possible.

This minimizes gaps and thus reduces the likelihood of water ingress.
- the washer 5 is designed so that it covers the distance between the primary flywheel 2 and the thrust ring 4 in the axial direction on the one hand, and on the other hand projects over the radial outside of the thrust ring 4 in the axial direction, so that through-openings to area 100 are also minimized here.
