Description

Torsional vibration damper assembly and hybrid module
Technical Field
The invention relates to a torsional vibration damper arrangement comprising a torsional vibration damper, in particular for a drive train of a motor vehicle, comprising a primary flywheel which can be coupled on a drive side to the drive train and a secondary flywheel which can be coupled on a driven side to the drive train, wherein the primary flywheel and the secondary flywheel can be rotated relative to one another about a common axis of rotation against the action of at least one spring device, wherein the secondary flywheel has an intermediate damper comprising an input part and an output part, wherein the input part and the output part can be rotated relative to one another about the axis of rotation, in particular against the action of an intermediate damper spring. The invention also relates to a hybrid module with a torsional vibration damper assembly.
Background
The drive train of a hybrid vehicle comprises a combination of an internal combustion engine and an electric motor and enables electric-only operation, for example, in densely populated areas even when driving over long distances while at the same time satisfying sufficient reach and availability. In addition, the internal combustion engine and the electric motor can be driven simultaneously in specific operating situations.
Conventionally, a torsional vibration damper is installed in such a hybrid drive train in order to damp vibrations between the engine and the transmission. Especially in the case where the internal combustion engine does not output a constant torque. The continuously changing angular speed of the crankshaft generates vibrations that can be transmitted to the vehicle transmission via the clutch system and the transmission input shaft. Where the vibrations may cause undesirable rattling noise. The torsional vibration damper should reduce this vibration between the motor and the transmission.
Torsional vibration dampers are known in principle for damping torsional vibrations of the drive shaft of a motor vehicle engine. For example, DE 102008004150 a1 discloses a dual mass flywheel, in which a primary flywheel is coupled to a secondary flywheel, which can rotate relative to the primary flywheel, via a curved spring, in order to damp torsional vibrations of a crankshaft of an internal combustion engine. The arcuate springs are arranged in arcuate spring channels, wherein channel walls of the arcuate spring channels are formed by the primary flywheel. The flange of the secondary flywheel projects into the curved spring channel, which is supported on the channel wall via a friction ring. Troublesome sealing measures must often be taken when the slip clutch is positioned in a greased arcuate spring channel in the torsional vibration damper.
In the case of torsional vibration dampers, so-called pre-dampers or intermediate dampers are also known, the task of which is to ensure a soft spring-up when idling or when the vibration angle is small, in order to avoid possible noise generation and to improve the quietness of the torsional vibration damper in operation.
Disclosure of Invention
It is therefore an object of the present invention to provide a torsional vibration damper assembly with an intermediate damper which is better in terms of its sealing measures and also in terms of installation space requirements and installation friendliness. It is also an object of the present invention to achieve a hybrid module with an improved torsional vibration damper assembly.
This object is achieved by a torsional vibration damper assembly comprising a torsional vibration damper, in particular for a drive train of a motor vehicle, comprising a primary flywheel which can be coupled on a drive side to the drive train and a secondary flywheel which can be coupled on a secondary side to the drive train, wherein the primary flywheel and the secondary flywheel are rotatable relative to each other about a common axis of rotation against the action of at least one spring means, wherein the secondary flywheel has an intermediate damper comprising an input part and an output part, wherein the input part and the output part are rotatable relative to each other about a rotational axis, in particular against the action of an intermediate damper spring, the output part is configured as an annular disk extending in a radial plane and is axially engaged between two support disks of a wet slip clutch loaded by a spring force.
The torsional vibration damper arrangement according to the invention requires less axial installation space than a combination of a slip clutch with dry pads and intermediate damper, since wet friction pads, for example paper pads, can be designed significantly thinner than dry pads. Furthermore, the use of a wet running slip clutch eliminates the seals required for dry applications, thereby also simplifying the installation of the torsional vibration damper assembly.
Force transmission can also occur diametrically, so that the flange has no leverage as in typical wet slip clutch applications, where the flange projects very far radially over the driving plate. A further advantage of the invention is that the friction ring/support on the engine side can also be designed to be significantly smaller in the radial direction, since it is not necessary to seal the slip clutch.
Further advantageous embodiments of the invention are given in the dependent claims. The features which are embodied individually in the dependent claims can also be combined in a technically meaningful manner and can define further embodiments of the invention. Furthermore, the features specified in the claims are explained and illustrated in greater detail in the description, in which further preferred embodiments of the invention are shown.
The individual elements of the invention object that are first claimed are set forth in the claims in the order of their names and particularly preferred embodiments of the invention object are described below.
In a possible embodiment, the torsional vibration damper can be designed as a dual-mass flywheel. The dual mass flywheel may comprise, inter alia, a primary flywheel, a secondary flywheel, a rotating slide bearing, one or more spring means and possibly one or more damper means. In a dual mass flywheel (ZMS), the flywheel is divided into a primary flywheel mass (primary flywheel) and a secondary flywheel mass (secondary flywheel). A spring device is arranged in the torque flow between the primary flywheel and the secondary flywheel, which spring device connects the primary flywheel and the secondary flywheel to one another in a soft torsional manner.
The spring means may in particular comprise a curved spring. In order to damp the torsion between the primary flywheel and the secondary flywheel, a damping device, for example in the form of a friction clutch, is preferably arranged in the torque flow between the primary flywheel and the secondary flywheel.
The primary flywheel has the function of coupling the drive side of the dual mass flywheel with the spring means. The primary flywheel can be designed in particular in multiple parts and comprises a primary flywheel disk which is connected to the primary hub, in particular via a primary connecting disk. The primary flywheel disk and the primary connecting disk can preferably be connected to one another in a rotationally fixed manner by way of rivets.
The primary flywheel may in particular have a receptacle for a spring device. Preferably, the receptacle, in particular for the bow spring, is arranged in the primary flywheel in a channel-like manner. It is particularly preferred that the receptacle for the spring device is integrally formed with the primary flywheel.
Preferably, the intermediate damper has an input part and an output part, wherein the input part and the output part can be rotated about the axis of rotation relative to one another against the action of the intermediate damper spring. In principle, it is naturally also conceivable for the intermediate damper to have no intermediate damper spring.
The motor vehicle in this application is a land vehicle that moves by machine power without being associated with a track. The motor vehicle can be selected from the group of a passenger car (PKW), a commercial vehicle (LKW), a scooter, a motor vehicle, a motorcycle, a motor bus (KOM), or a tractor, for example. Hybrid Electric vehicles, also referred to as Hybrid Electric Vehicles (HEV), are Electric vehicles which are driven by at least one Electric motor and a further energy converter and which draw energy from their Electric storage (Akku) and additionally from the fuel which is carried along.
In the present application, a drive train of a motor vehicle is understood to mean all components which generate power for driving the motor vehicle in the motor vehicle and which are transmitted to the road via the wheels.
The advantageous configuration according to the invention makes it possible for the primary flywheel to have a U-shaped section in cross section which is open radially inward and in which the spring device and the intermediate damper spring are accommodated. The advantage of this embodiment is that the spring is well protected against axial forces. Furthermore, the possibility is also provided for the channel-like annular space to be completely or partially filled with a lubricant, for example grease, or for lubricating the relatively movable elements of the torsional vibration damper and/or the intermediate damper.
According to a further preferred development of the invention, the input part of the intermediate damper can also be supported axially on the U-shaped section, so that an axially particularly compact embodiment of the torsional vibration damper is possible.
Furthermore, according to an equally advantageous embodiment of the invention, the input part of the intermediate damper is axially supported via a first support ring, which is arranged axially between the primary flywheel and the input part, and a second support ring, which is arranged axially between the free limb of the U-shaped section and the input part, wherein the first support ring and/or the second support ring is/are loaded with a spring force in the axial direction. Thus, in addition to the axial support, a sealing of the U-shaped section is also possible.
According to a further particularly preferred embodiment of the invention, the wet slip clutch can be spring-loaded by a wrap spring, so that a defined friction load of the slip clutch can be set.
The invention is further improved in that an oiled paper pad is provided as a friction pad on the support disk and/or the output element, as a result of which the compact design of the torsional vibration damper can be further optimized.
In an equally preferred embodiment of the invention, the slip clutch can also be arranged radially below the U-shaped section.
The invention can also be advantageously further developed in that the spiral spring is supported axially on a third support disk, which is positioned axially spaced apart from the two support disks, whereby the compact design of the torsional vibration damper can likewise be optimized.
A further preferred embodiment of the object according to the invention makes it possible to connect the two support disks and the third support disk in a rotationally fixed manner relative to one another, in particular via a rivet.
The object of the invention is also achieved by a hybrid module for a drive train of a motor vehicle, wherein the hybrid module is arranged in the drive train, in particular between an internal combustion engine of the motor vehicle and a vehicle transmission, the hybrid module comprising an electric motor and a torsional vibration damper assembly according to any one of claims 1 to 9.
The structural and functional elements of the hybrid drive train can be combined and configured spatially and/or structurally in the hybrid module, so that the hybrid module can be integrated into the drive train of the motor vehicle in a particularly simple manner. In particular, in hybrid modules, an electric motor and a clutch system, in particular with a separating clutch, may be present for coupling the electric motor into the drive train or for coupling the electric motor out of the drive train.
Hybrid modules can be classified into the following categories P0-P4 according to the motor's engagement point in the drive train.
P0: the electric motor is arranged upstream of the internal combustion engine and is coupled to the internal combustion engine, for example, via a belt. In the arrangement of the electric motor, sometimes referred to as a belt starter generator (RSG),
p1: the electric motor is arranged directly after the internal combustion engine. The electric motor can for example be arranged fixedly with the crankshaft before the starting clutch,
p2: the electric motor is arranged between the disconnect clutch, generally referred to as K0, and the starting clutch but before the vehicle transmission in the drive train,
p3: the electric motor is arranged in the vehicle transmission and/or in the transmission output shaft,
p4: the electric motor is arranged on an existing or separate axle, an
P5: the electric motor is arranged on or in the wheel, for example as a hub motor.
An electric motor is a motor that converts electrical power into mechanical power. Usually a conductor coil through which a current flows in the motor generates a magnetic field which converts the mutual attractive and repulsive forces into a movement.
A vehicle transmission is a transmission in the drive train of a motor vehicle, which accelerates the engine speed to the driver speed.

In particular, without explicit indication to the contrary, partial solutions can also be extracted from the objects mentioned in the figures and combined with other components and teachings in the present description and/or in the figures. It should be noted in particular that the drawings and the dimensional ratios shown in particular are purely schematic. The same reference numerals denote the same objects, and the description may be supplemented from other drawings as necessary.
In which is shown:

Fig. 2 shows a block diagram of a motor vehicle with a hybrid module.
Detailed Description
Fig. 1 shows a torsional vibration damper arrangement 1, which comprises a torsional vibration damper 2 for a drive train 3 of a motor vehicle 4, as is shown by way of example in fig. 2.
The torsional vibration damper arrangement 1 comprises a primary flywheel 5, which can be coupled on the drive side to the drive train 3, and a secondary flywheel 6, which can be coupled on the output side to the drive train 3. The primary flywheel 5 and the secondary flywheel 6 are rotatable relative to each other about a common axis of rotation 7 against the action of a spring device 8. The secondary flywheel 6 has an intermediate damper 9 comprising an input part 10 and an output part 11, wherein the input part 10 and the output part 11 can be rotated relative to one another about the axis of rotation 7 against the action of an intermediate damper spring 12.
As can also be seen from fig. 1, the cross section of the primary flywheel 5 has a U-shaped section 15 which is open radially inward and in which the spring device 8 and the intermediate damper spring 12 are accommodated. The input part 10 of the intermediate damper 9 is supported in the axial direction by means of a first support ring 21, which is arranged axially between the primary flywheel 5 and the input part 10, and a second support ring 22, which is arranged axially between the free limb of the U-shaped section 15 and the input part 10. In the embodiment of the invention shown, the second support ring 22 is spring-loaded in the axial direction. The support rings 21, 22 in particular also serve here as seals and define the annular space defined by the U-shaped section 15 and the support rings 21, 22. The spring means 8 and the intermediate damper spring 12 are accommodated in this space.
There are regions between the output part 11 and the input part 10 of the intermediate damper 9 which are not sealed for system reasons, since the parts 10, 11 which move relative to one another are not completely sealed relative to one another. Since the annular space which is at least partially accommodated in the intermediate damper 9 can be filled with grease, lubrication of the relatively moving parts 10, 11 can be achieved and wear thereof can be reduced.
The output part 11 of the intermediate damper 9 is designed as an annular disk extending in a radial plane 20 and is axially engaged between two support disks 13 of a spring-loaded wet slip clutch 14. The wet slip clutch 14 is arranged radially below the U-shaped section 15 and is spring-loaded in the axial direction by a disk spring 23. Oiled paper pads are provided as friction pads on the support plate 13 and the output member 11.
The spiral spring 23, which bears against the support disk 13 on the side facing away from the primary flywheel 5, is supported axially on a third support disk 19, which is positioned axially spaced apart from the two support disks 13. The two support disks 13 and the third support disk 19 are connected in a rotationally fixed manner to one another by way of rivets which are not illustrated in detail in fig. 1.
The slip clutch 14 is coupled on the output side in a rotationally fixed manner to a sleeve, not shown in detail, in the drive train 3.
Fig. 2 shows a hybrid module 24 for a drive train 3 of a motor vehicle 4, wherein the hybrid module 24 is arranged in the drive train 3 between an internal combustion engine 25 and a vehicle transmission 26 of the motor vehicle 4. The hybrid module 24 comprises an electric motor, which is not shown in fig. 2, and the torsional vibration damper arrangement 1 known from fig. 1.
The invention is not limited to the embodiments shown in the drawings. The foregoing description is therefore not to be taken in a limiting sense, but is made for the purpose of explanation. The following claims may be construed to include such features in at least one embodiment of the invention. This does not exclude the presence of other features. If the claims and the preceding description define "first" and "second" features, the names are used to distinguish two features of the same type without determining an order of preference.
