Technical Field
The invention relates to a clutch disc for a friction clutch of a motor vehicle, such as a passenger car, a truck, a bus or another commercial vehicle, having an input which is rotatable about an axis of rotation and has friction linings, having an output which is also rotatably arranged about the axis of rotation (preferably further connected to a wheel hub), and having a pendulum damper connecting the input and the output, wherein the pendulum damper comprises two parts which are rotatable relative to one another about an axis of rotation within a limited angular range, comprising a flange region interacting with the input and the output, and a plurality of intermediate parts which are mounted in an oscillating manner by means of sliding means in a first flange region and a second flange region, respectively, which, when the first flange region is rotated relative to the second flange region, the intermediate portions are each prevented from movement (relative to the flange area) by spring means. The invention also relates to a friction clutch with the clutch disc.
Background
Generic clutch discs are known from the prior art. For example, DE 102015211899 a1 discloses a rotary vibration absorber which can be used in a clutch disk and which is composed of an input, an output and a spring device.
However, a disadvantage of the embodiments known from the prior art is that the sliding device (Kulisseneinrichtungen) used therein is generally relatively large and expensive to produce. In particular when moving multi-dimensional running rails (running at an angle to one another) in a corresponding sliding device, the flange area and/or the intermediate part must be sufficiently large. This effect is even more pronounced in the case of relatively large rotation angles of the intermediate part/flange region and spring paths of the spring device. In addition, the forces generated on the slide (which act on the roller contact surfaces if rollers are provided in the slide) require that the components of the slide be of sufficient size (e.g., the rollers need to be of a certain diameter) to achieve an acceptable pressure. It is therefore also necessary to form larger-sized openings in the respective parts (along the roller track). This is disadvantageous both with respect to the size of the components and the installation space of the entire assembly. Furthermore, known embodiments often result in inconsistent torque characteristics by implementing multiple curved portions that run transverse to each other. As a result, jerks and sudden movements can act on the components of the sliding device during operation and thus lead to relatively high component loads.
Disclosure of Invention
The object of the present invention is therefore to eliminate the disadvantages known from the prior art and in particular to provide a clutch disk with a pendulum damper which is compact on the one hand and which exerts as smooth a load as possible on the components during operation on the other hand.
According to the invention, the above task is achieved by: the sliding means are designed and each flange region is operatively connected to the input and the output such that the two flange regions move relative to each other in a single/common fixed direction of movement when the direction of action of the resultant load on the input changes from a first direction of rotation to a second direction of rotation opposite to the first direction of rotation and when the direction of action changes from the second direction of rotation to the first direction of rotation.
This causes the flange regions to move relative to each other along a linear path. Thus, the components of the pendulum absorber can be manufactured at a lower cost. For example, only linear slides are required in the respective slide. This significantly reduces the loading of the individual components of the pendulum absorber during operation. A sudden/abrupt increase of the load on the component is thus avoided. As a result, the size of each component can be reduced accordingly, and the installation space can be saved, or the entire clutch disc can be designed to have higher performance.
Further advantageous embodiments are claimed by the dependent claims and are explained in more detail below.
With regard to the connection of the pendulum absorber, it is advantageous if the first flange region is rotatable within a first angular range (within a limited range) relative to the input and/or the output. It is therefore likewise advantageous if the second flange region is rotatable within a second angular range relative to the input and/or output. This makes the interface between the pendulum absorber and the respective input and output particularly easy to manufacture. In this case, it is useful if the first and second angular ranges are the same size.
Furthermore, it is advantageous if the first flange region has a first stop which is matched to the input (i.e. interacts with a (first) counter-stop of the input) such that when the input is rotated in the first rotational direction it rests against the first stop (first flange region) for rotation therewith and when the input is rotated in the second rotational direction it can be rotated/spaced (within a limited range) relative to the first flange region.
In this case, it is likewise useful if the second flange region has a first stop which is matched to the input (i.e. interacts with a (second) counter-stop of the input opposite the first counter-stop) such that, when the input is rotated in the second direction of rotation, it bears non-rotatably against the first stop (first flange region) for rotation therewith, and, when the input is rotated in the first direction of rotation, it can be rotated/spaced (within a limited range) relative to the second flange region. This makes it particularly easy to establish the connection of the flange region to the input.
It is therefore also advantageous for reception on the output if the first flange region has a second stop matching the output (i.e. interacting with a (first) counter-stop of the output) so that when the output is rotated in the first rotational direction it rests on this second stop for rotation therewith and when the output is rotated in the second rotational direction it can be rotated/spaced (within a limited range) relative to the first flange region.
In this case, it is likewise useful if the second flange region has a second stop which is matched to the output (i.e. interacts with a (second) counter-stop of the output which is opposite to the first counter-stop) such that, when the output is rotated in the second direction of rotation, it bears against the second stop for rotation therewith, and, when the output is rotated in the first direction of rotation, it can be rotated (within a limited range) relative to the second flange region. The respective flange region on the output side is therefore also connected in a specific technology.
Thus, the (first) stop is attached to the first and second flange regions such that the output and the input are in contact with the respective flange regions during rotation in the first rotational direction. The (second) stop is also attached to the first and second flange regions such that the output and input are in contact with the respective flange regions during rotation in the second rotational direction.
The multi-stage torque characteristic of the pendulum absorber can be easily achieved if the spring device has a variable spring rate along its spring path.
In this case, it is also useful if the spring device consists of a spring unit having a plurality of spring elements, preferably arranged parallel to one another, and acting between the intermediate portions.
It is also advantageous if each intermediate part is connected to the first flange region via a first linear guide and to the second flange region via a second linear guide which runs at an angle to the first linear guide.
The invention further relates to a friction clutch for a drive train of a motor vehicle, having a clutch plate according to the invention, serving as a first clutch component according to at least one of the aforementioned embodiments, and a second clutch component which can be connected to the clutch plate by means of friction.
In other words, according to the present invention, a clutch disc with a pendulum damper is achieved, wherein the input flange and the output flange (the first flange region and the second flange region) move relative to each other in only one direction even if the load direction changes. Only a (straight) part of the previous path curve is needed.
