Description

Device comprising a pulley decoupler and a torsional vibration damper
Technical Field
The invention relates to a device comprising a pulley decoupler and a torsional vibration damper, which have a common axis of rotation. The pulley decoupler has an input side and an output side and at least one first spring element acting between the input side and the output side, by means of which the input side and the output side can be twisted relative to one another in the circumferential direction. The torsional vibration damper has a flange member.
Background
The pulley decoupler is particularly designed for attaching the pulley at the crankshaft of a drive machine, for example a motor vehicle. The transmission of torsional vibrations, for example of the drive mechanism, to the belt driven by the belt pulley should therefore at least be reduced or avoided. However, the pulley decoupler can also form a dual-mass flywheel.
Torsional vibration dampers are torsional flexures that are purposefully introduced into a drive train excited with periodic disturbances. The aim is to shift the disturbing oscillation resonances occurring in different operating situations into a rotational speed range which is as low as possible below the operating rotational speed. The vibration resonances remaining in the operating rotational speed range are damped by external or integrated friction devices, the friction torques of which should lie within defined limits. In particular, the friction means may be constructed separately from the torsional flexure and therefore are not considered in the following. In particular, the torsional flexible element together with the friction device is referred to below as a torsional vibration damper device.
Devices comprising a pulley decoupler and a torsional vibration damper having a common axis of rotation are known, for example, from EP 2827014 a1 and DE 102017115466 a 1.
In DE 102017115466 a1 and EP 2827014 a1, a torsional vibration damper and a pulley decoupler are respectively provided at the hub. The output side is rotatably supported at the hub. A spring element and a sealing element are arranged between the output side and the flange part of the torsional vibration damper.
There is a continuing need to simplify or adapt components for motor vehicles, such as devices comprising pulley decouplers and torsional dampers, to particular applications.
Disclosure of Invention
Starting from this, the invention is based on the object of providing a device which is as simple as possible and in particular comprises as few components as possible.
Said object is achieved by means of a device according to the invention comprising a pulley decoupler and a torsional vibration damper. Further advantageous embodiments of the invention are described in the examples. The features listed individually in the examples can be combined with one another in a technically meaningful manner and can define further embodiments of the invention. Furthermore, the features specified in the claims are specified and set forth in the description, wherein further preferred embodiments of the invention are shown.
An apparatus is proposed comprising a pulley decoupler and a torsional vibration damper, which have a common axis of rotation. The pulley decoupler has an input side and an output side, which can be rotated relative to one another in the circumferential direction against the spring action of at least one first spring element, and at least one first spring element which acts between the input side and the output side. The torsional vibration damper has a flange part and is connected to the input side in a rotationally fixed manner via the flange part. The output side is rotatably supported on the flange part via a first bearing arranged between the output side and the flange part.
In particular, the output side (also referred to as belt attachment region, since the output side can be connected in a rotationally fixed manner to the belt via the belt portion or the output side can be connected in a rotationally fixed manner to the belt via the belt portion) can be rotated (for example by an angle of at most 30 degrees, for example, extending in the circumferential direction) against the spring force of the at least one first spring element relative to the input side (also referred to as shaft attachment region, since the input side can be connected in a rotationally fixed manner to the shaft, for example, the crankshaft, or the input side can be connected in a rotationally fixed manner to the shaft, for example, the crankshaft). The rotation is limited, for example, by stops (first stop, second stop).
In particular, the at least one first spring element is supported by means of a spring force acting in the circumferential direction at a first stop on the input side and at a second stop on the output side.
In particular, torsional vibrations can be at least reduced via a relative rotation of the input side relative to the output side, which is effected against the spring force and, if appropriate, against the damping effect.
The first bearing serves in particular to support the output side on the flange part, wherein the output side and the flange part can be twisted relative to one another in the circumferential direction. The first bearing is in particular only able to achieve a torsion of the output side relative to the flange part, wherein the first bearing preferably has no elastic deformability. The device is designed in particular such that the output side is pressed against the flange part, for example via a spring force, wherein the position of the output side relative to the flange part is determined at least with respect to the radial direction and/or the axial direction by means of the in particular non-deformable first bearing.
In particular, the first bearing is a plain bearing. In plain bearings, two parts which move relative to one another (here the flange part and the plain bearing and/or the output side and the plain bearing) are in direct contact with one another. The two components slide against each other against resistance caused by sliding friction. In contrast to rolling bearings, plain bearings in particular do not have rolling bodies.
In particular, the output side is supported at the flange part at least with respect to the radial direction via a first bearing.
In particular, the flange part has a section extending in the axial direction, at which section a first bearing is provided. In particular, the first bearing has a cylindrical shape and extends in a circumferential direction as well as in an axial direction (i.e. parallel to the rotation axis).
In particular, the section is arranged along the extension of the flange part between the attachment at the hub and the damper section, wherein a torsional damping device (i.e. a torsional flexure, for example together with a friction device) is arranged in the damper section (of the torsional damper).
In particular, the output side is supported at the flange part at least with respect to the axial direction via a first bearing.
In particular, the first bearing is implemented in two parts. The first part supports the output side at the flange part with respect to the radial direction, and the second part supports the output side at the flange part with respect to the axial direction. In particular, the two components are arranged directly next to one another.
The axial direction extends in particular parallel to the axis of rotation.
In particular, the output side comprises a first cover section which is arranged in the axial direction between the at least one first spring element and the flange part, wherein the first bearing is arranged at the first cover section. In particular, the first cover section extends from the output-side belt section in the radial direction inward.
In particular, the first cover section also extends in the axial direction and forms an abutment surface which is arranged opposite the section of the flange part. In particular, the first bearing (or the first part of the first bearing) is arranged between the abutment surface and the section.
In particular, the output side has a belt section and a second cover section extending from the belt section in the radial direction inwardly, wherein the second cover section is rotatably supported at the input side via a second bearing.
In particular, the at least one first spring element is arranged in the axial direction between the first cover section and the second cover section. In particular, the first cover section, the belt section and the second cover section form a housing for the at least one first spring element. In particular, the housing may be at least partially filled with a fluid (lubricant, for example grease).
In particular, at least the first or the second cover section, preferably both the first and the second cover section, has at least one second stop for supporting the spring force of the at least one first spring element relative to the circumferential direction. In particular, the first stop of the input side is arranged in the axial direction between the first cover section and the second cover section.
In particular, a second spring element is provided between the second cover section and the input side, via which second spring element the output side is supported at the input side with respect to the axial direction. In particular, the output side is pressed against the flange component via the second spring element.
In particular, the second spring element forms a second bearing, for example together with the material forming the plain bearing. In particular, a friction ring is provided at least at the input side or at the output side (preferably at both sides, respectively), which friction ring at least partially forms the second bearing, via which friction ring the second spring element is arranged torsionally at the output side or at the input side.
In particular, the second spring element can achieve a sealing of the first spring element or the housing from the environment.
In particular, the second spring element extends at least circumferentially around the rotational axis. In particular, the second spring element is a disk spring.
In particular, the input side and the flange part are connected to the hub in a rotationally fixed manner, wherein the device can be arranged on the shaft via the hub in a rotationally fixed manner.
The shaft is, for example, a crankshaft of a drive unit, such as an internal combustion engine. In particular, the pulley decoupler is arranged in the axial direction between the torsional vibration damper and the drive unit. In particular, the drive unit is arranged between the transmission and the device in the axial direction.
In particular, the device may be used in a motor vehicle. The other components of the motor vehicle can be connected to the crankshaft via a belt of the belt pulley decoupler, so that the kinetic energy of the drive unit can be transmitted to the other components.

Fig. 1 shows a section of a first embodiment variant of a device 1 known from EP 2827014 a1 in a side view. The device comprises a pulley decoupler 2 and a torsional vibration damper 3 having a common axis of rotation 4. The pulley decoupler 2 has an input side 5 and an output side 6 and a first spring element 7 which acts between the input side 5 and the output side 6 and by means of which the input side 5 and the output side 6 can be twisted relative to one another in a circumferential direction 8.

Fig. 2 shows a section of a second embodiment variant of the device 1 known from DE 102017115466 a1 in a side view. Reference is made to the embodiment relating to figure 1.
In DE 102017115466 a1 and EP 2827014 a1, the torsional vibration damper 3 and the pulley decoupler 2 are each arranged at the hub 15. The output side 6 is rotatably mounted via a first bearing 10 at a hub 15. A second spring element 22 and a sealing element 26 or a friction ring 31 are arranged between the flange part 9 and the output side 6 of the torsional vibration damper 3.
Fig. 3 shows a cross section of the device 1 in a side view. The device 1 comprises a pulley decoupler 2 and a torsional vibration damper 3 having a common axis of rotation 4. The pulley decoupler 2 has an input side 5 and an output side 6 and at least one first spring element 7 which acts between the input side 5 and the output side 6, against the spring action of which the input side 5 and the output side 6 can be twisted relative to one another in the circumferential direction 8. The torsional vibration damper 3 has a flange part 9 and is connected to the input side 5 in a rotationally fixed manner via the flange part 9. The output side 6 is rotatably supported at the flange part 9 via a first bearing 10 arranged between the output side 6 and the flange part 9.
The output side 6 can be twisted relative to the input side 5 against the spring force of the at least one first spring element 7. The rotation is limited by the stops (first stop 24, second stop 25).
At least one first spring element 7 is supported by means of a spring force acting in the circumferential direction 8 at a first stop 24 on the input side 5 and at a second stop 25 on the output side 6.
The first bearing 10 serves to support the output side 6 at the flange part 9, wherein the output side 6 and the flange part 9 can be twisted relative to one another in the circumferential direction 8. The first bearing 10 can only achieve a torsion of the output side 6 relative to the flange part 9, wherein the first bearing 10 is not elastically deformable. The device 1 is designed such that the output side 6 is pressed against the flange part 9 via the spring force of the second spring element 22, wherein the position of the output side 6 relative to the flange part 9 is determined by the non-deformable first bearing 10 with respect to the radial direction 11 and the axial direction 12.
The first bearing 10 is a plain bearing. In the case of a plain bearing, the two parts which move relative to one another (here the flange part 9 and the plain bearing and the output side 6 and the plain bearing) are in direct contact with one another. The two components slide against each other against resistance caused by sliding friction.
The output side 6 is supported at the flange part 9 with respect to the radial direction 11 via the first part 27 of the first bearing 10.

The first bearing 10 or the first part 27 of the first bearing 10 has a cylindrical shape and extends in the circumferential direction 8 as well as in the axial direction 12, i.e. parallel to the axis of rotation 4.
The section 13 is arranged along the extension of the flange part 9 between the attachment 14 at the hub 15 and a damper section 16, wherein a torsional vibration damper arrangement 17 (i.e. a torsional flexure, for example together with a friction device) is arranged in the damper section 16 (of the torsional vibration damper 2).
The output side 6 is also supported at the flange part 9 with respect to the axial direction 12 via the first bearing 10 or the second part 28 of the first bearing 10.
The first bearing 10 is implemented in two parts. The first part 27 supports the output side 6 at the flange part 9 with respect to the radial direction 11, and the second part 28 supports the output side 6 at the flange part 9 with respect to the axial direction 12.

The first cover portion 18 also extends in the axial direction 12 and forms an abutment surface 29 which is arranged opposite the portion 13 of the flange part 9. Between the contact surface 29 and the section 13, the first bearing 10 (or the first part 27 of the first bearing 10) is arranged.
The output side 6 has a belt section 19 and a second cover section 20 extending from the belt section 19 inward in the radial direction 11, wherein the second cover section 20 is rotatably supported at the input side 5 via a second bearing 21.
At least one first spring element 7 is arranged between the first cover section 18 and the second cover section 20 along the axial direction 12. In particular, the first cover portion 18, the belt portion 19 and the second cover portion 20 form a housing 30 for the at least one first spring element 7. The housing 30 may be at least partially filled with a fluid (lubricant, such as grease).
In particular, the first cover section 18 and the second cover section 20 each have at least one second stop 25 for supporting the spring force of the at least one first spring element 7 relative to the circumferential direction 8. A first stop 24 of the input side 5 is arranged between the first cover section 18 and the second cover section 20 along the axial direction 12.
Between the second cover section 20 and the input side 5, a second spring element 22 is provided, via which the output side 6 is supported at the input side 5 with respect to the axial direction 12. The output side 6 is pressed against the flange part 9 via the second spring element 22.
Friction rings 31 are provided on the input side 5 and on the output side 6, which friction rings together form the second bearing 21, via which friction rings the second spring element 22 is arranged in a rotatable manner on the output side 6 and/or on the input side 5.
The second spring element 22 can be used together with a friction ring 31 designed as a sealing element 26 to seal the first spring element 7 or the housing 30 from the environment 32.
The second spring element 22 extends circumferentially around the axis of rotation 4 in the circumferential direction 8. The second spring element 22 is a belleville spring.
The input side 5 and the flange part 9 are connected in a rotationally fixed manner with the hub 15 via the attachment 14, wherein the device 1 is arranged at the shaft 23 in a rotationally fixed manner via the hub 15.
