-arranging the torque limiting device between the input element and the output element.
A known torque transmission device is known, for example, from DE 102012211990 a 1. The torque transmission device, in particular for a drive train of a motor vehicle driven by a combustion engine, comprises: an input and an output with a common axis of rotation, the input and the output being rotatable together about the axis of rotation and being limitedly rotatable relative to each other; at least one energy store acting between the input and the output, the at least one energy store being supported on the one hand on the input and on the other hand on the output; and a torque limiting device arranged kinematically between the at least one energy store and the input or output, wherein the torque limiting device has a support section on which the at least one energy store is supported and which bears against the input or output in a form-fitting and force-fitting manner, and a spring section which urges the support section against the input or output with a pretension and enables the support section to be released from the input or output by elastic jumping if the supporting force of the at least one energy store on the support section exceeds a predetermined value.
However, the disadvantages here are: the torque transfer devices are complex in design and expensive to manufacture.
It is therefore an object of the present invention to provide a torque transmission device which is capable of limiting torque peaks, while being simple in design and cost-effective to manufacture.
Another object of the invention is to provide an alternative torque transmission device and an alternative method for producing the same.
The invention achieves the above-mentioned object in the form of an embodiment of a torque transmission device, in particular for a drive train of a motor vehicle, comprising an input element and an output element which are rotatable relative to one another about a common axis of rotation by means of an energy storage device, and wherein a torque limiting device is arranged between the input element and the output element, wherein the torque limiting device is designed for: below a torque value, torque is transmitted between the input element and the output element and above the torque value, torque is at least partially not transmitted, whereby the torque limiting device is connected to the energy storage device by a force-fit and/or form-fit connection and to the input element by a friction-fit connection.
The invention achieves the above object in an embodiment in the form of a method for manufacturing a torque transmission device, in particular for a power train of a motor vehicle, comprising:
providing an input element;
providing an output element;
providing an energy storage device;
providing a torque limiting device, wherein the torque limiting device is designed for: below a torque value, torque is transmitted between the input element and the output element, and above the torque value, torque is at least partially not transmitted, in particular not transmitted at all;
arranging the input element and the output element relative to each other through the energy storage device and rotatable about a common axis of rotation;
arranging the torque limiting device between the input element and the output element,
the torque limiting device is thereby connected to the energy storage device by a force-fit and/or form-fit connection and to the input element by a friction-fit connection.
One of the advantages achieved thereby is that an easy and cost-effective manufacture and design can be achieved. Furthermore, an alternative torque transmission device and a method for producing a torque transmission device are specified.
Additional features, advantages, and other embodiments of the invention will be set forth in the description which follows or may be disclosed in connection with the embodiments.
According to an advantageous further development, the torque limiting device comprises an axially pretensioned element for providing the friction-fit connection. This enables a connection that provides a friction fit easily and cost effectively. By means of the axial pretensioning, the friction force and thus the limitation of the torque can be adjusted in a particularly simple manner.
According to a further advantageous development, the axially pretensioned element has a first region which is arranged laterally next to the energy storage device in the axial direction and which is designed to provide a friction-fit connection with the input element. This makes efficient use of the installation space next to the energy storage device.
According to a further advantageous development, the first region of the axially prestressed element is designed to provide a force-and form-fitting connection with the energy storage device. This provides a space-efficient force-fit and form-fit connection between the axially prestressed element and the energy storage device.
According to a further advantageous development, the axially prestressed element is of substantially L-shaped design in cross section, wherein the first region forms the longer leg of the L-shape. Thus, an axial pretensioning element which is easy to produce and at the same time is space-efficient can be provided.
According to a further advantageous development, the axially prestressed element has a second region which is U-shaped in cross section, such that the first region and a part of the second region are arranged parallel in cross section. One of the advantages achieved thereby is that a simple and reliable transmission of torque is provided between the axially prestressed element and the energy storage device.
According to a further advantageous development, the second region is integrally connected to the first region. This has the advantage that a cost-effective manufacture of both regions can be achieved. Complex two-piece manufacturing is avoided.
According to a further advantageous development, at least one support surface, in particular two support surfaces, are arranged in the circumferential direction on the second region. This provides a simple connection between the axially prestressed element and the energy storage device.
According to a further advantageous development, the at least one support surface is curved. This has the advantage that a low-wear connection between the axially prestressed element and the energy storage device can be achieved and a reliable torque transmission can be achieved.
According to a further advantageous development, the at least one support surface has a projection in the circumferential direction in the radial direction outwards. This prevents the elements of the energy storage device which interact with the support element from being displaced radially outward, which increases the reliability of the torque transmission device.
According to a further advantageous development, the at least one supporting surface is integrally formed on the second region. This enables an easy and cost-effective manufacture of the support surface.
According to a further advantageous development, the at least one support surface is arranged on a plug element which is designed to be plugged onto the second region. Thereby increasing flexibility. Depending on the requirements for the bearing surface, different plug elements for different torque transmission devices can be used.
According to a further advantageous development, the axially prestressed element is arranged in the circumferential direction. One of the advantages achieved thereby is that a sufficiently large friction surface is provided, which improves the reliability in the torque transmission; the axially pretensioned element thus forms a loop.
According to a further advantageous development, the axially pretensioned element can be pretensioned by means of a housing part arranged on the output side. This allows a simple assembly of the axially prestressed element.
Further important features and advantages of the invention emerge from the dependent claims, the figures and the associated description of the figures in accordance with the figures.
It goes without saying that the features mentioned above and those still to be explained below can be used not only in the respectively given combination but also in other combinations or alone without departing from the scope of the invention.
Preferred embodiments and implementations of the present invention are illustrated in the accompanying drawings and will be described in more detail in the following description, in which like reference numerals refer to identical or similar or functionally identical components or elements.
In schematic form in the drawings:
FIG. 1 illustrates, in cross-section, a torque transmitting device according to one embodiment of the present invention;
FIG. 2 shows a detail of an axially pretensioned element of the torque transmission device of FIG. 1 in a three-dimensional view;
FIG. 3 illustrates, in top plan view, a portion of a torque transmitting device according to one embodiment of the present invention; and
fig. 4 shows the steps of a method according to an embodiment of the invention.
Fig. 1 shows a torque transmission device according to an embodiment of the invention in cross section.
Fig. 1 shows a torque transmission device 1 in the form of a torsional vibration damper having an input part 2 in the form of a primary flywheel and an output part 3 mentioned here in the form of a hub disk in detail. The main flywheel 2 and the hub disk 3 can be rotated relative to one another about a common axis of rotation 100 by the energy storage device 4. Furthermore, a torque limiting device 10 is arranged between the main flywheel 2 and the energy storage device 4, wherein the torque limiting device 10 is designed to: below the torque value, torque is transmitted between the main flywheel 2 and the hub disk 3 and above the torque value, at least partially, no torque is transmitted. The torque limiting device 10 has an axially prestressed, essentially pot-shaped element 5, which is placed against the inside of the main flywheel 2 in a friction-fit manner by means of an axial prestressing and in this way transmits torque below a predeterminable maximum torque, for example by means of material selection and/or an axial prestressing. Above a predeterminable torque, the friction-fit connection provided by the axial pretensioning is eliminated, so that no torque is introduced into the energy storage device 4 and damage to the torque transmission device 1 is therefore avoided.
The pot-shaped element 5 is axially prestressed by means of a cover part 16 which forms an annular intermediate space 11 for the energy storage device 4 arranged in the circumferential direction on the driven side next to the main flywheel 2. For this purpose, the pot-shaped element has a section parallel to the rotational axis 100 radially above the energy storage device 4, which section merges in the region of the primary flywheel into a first region 6 extending radially inward. The first region 6 is pressed with a predeterminable force against the inside of the main flywheel on the basis of the axial pretensioning and, as already explained above, effects a friction-fit connection between the main flywheel 2 and the pot-shaped element 5. Furthermore, the pot-shaped element 5 has a second region 7 extending parallel thereto, which interacts with the spring plate 4a of the energy storage device 4. The energy storage device 4 has one or more spring raceways 4a that cooperate with the spring 4b to damp torsional vibrations. The pot-shaped element 5 can likewise have a suitable number of second regions 7 for interacting with the energy storage device 4.
Fig. 2 shows a detail of an axially pretensioned element of the torque transmission device of fig. 1 in a three-dimensional view.
Fig. 2 shows a detail of the axially prestressed element 5. The second region 7 of the pot-shaped element 5 has a plug element 15, which is plugged onto the second region 7 or is otherwise connected thereto (for example by means of a press fit or the like). The plug element 15 has two bearing surfaces 12a, 12b which are opposite in the circumferential direction and are designed concavely, for receiving corresponding convexly shaped surfaces of the respective spring retainer 4a of the energy storage device 4. The pot-shaped element 5 is designed in two parts. Alternatively, the pot-shaped element 5 can also be designed in one piece. The support surfaces 12a, 12b can be provided, for example, by a corresponding curvature of a part of the second region 7.
FIG. 3 illustrates, in top plan view, a portion of a torque transmitting device according to one embodiment of the present invention;
fig. 3 shows a substantially pot-shaped element according to fig. 2. In contrast to the pot-shaped element 5 according to fig. 2, the pot-shaped element 5 according to fig. 3 has two projections 13 on the radial outside, each in the opposite circumferential direction. The projection 13 prevents the spring plate 4a from bearing with its radially outer side on the entire radially inner side of the pot-shaped element 5, which makes it possible to design the bearing surfaces 12a, 12b more narrowly.
Fig. 4 shows the steps of a method according to an embodiment of the invention.
Fig. 4 shows the steps of a method for producing a torque transmission device, in particular for a drive train of a motor vehicle. The method comprises the following steps:
in a first step S1, an input element is provided.
In a further step S2, an output element is provided.
In a further step S3, an energy storage device is provided.
In a further step S4, a torque limiting device is provided, wherein the torque limiting device is designed for transmitting torque below a torque value and for at least partially not transmitting torque above the torque value.
In a further step S5, the input element and the output element are arranged to be rotatable relative to each other about a common axis of rotation by the energy storage device.
In another step S6, a torque limiting device is disposed between the input element and the output element.
In steps S1 to S6, the torque limiting device is connected to the energy storage device by a force-fit and/or form-fit connection and to the input element by a friction-fit connection.
In summary, at least one of the embodiments of the invention has at least one of the following features:
