Definitions
- the invention relates to an assembly for a hybrid drive train of a motor vehicle, comprising a first torque transmission device and a second torque transmission device connected therewith in terms of torque, the first torque transmission device being arranged axially spaced from the second torque transmission device, and wherein the second torque transmission device has a smaller radial extent has as the first torque transmission device and wherein in the radial direction above half of the second torque transmission device, a space for a drive train device is specified such that this is limited in the axial direction by the first torque transmission device.
- the invention further relates to a drive train, in particular a hybrid drive train of a motor vehicle with an assembly.
- Hybrid vehicles like conventional motor vehicles, have a drive train that is exposed to vibrations from prime movers.
- a vibration decoupling system is introduced into the torque transmission path of the drive train, for example a dual-mass flywheel, a damper and a torsion damper with an inner disk carrier for a clutch. Due to the manufacturing process, the individual elements of the vibration decoupling system have geometric deviations that cause an imbalance. To compensate for the imbalance, it has become known to arrange additional masses both on the damper and on the inner disc carrier.
- the disadvantage here is that the arrangement of two masses, of which the one on the inner disk carrier is usually arranged radially far inward due to the design, and thus has to be dimensioned accordingly large in order to provide sufficient compensation for the imbalance, is complicated and expensive.
- DE 10 2014 220 506 A1 discloses a centrifugal pendulum device with a protective device on the axial side facing away from the centrifugal pendulum an additional mass is arranged to compensate for an imbalance, has become known.
- the protective device surrounds the centrifugal pendulum device in the radial and axial directions.
- assemblies must also be adapted to a wide variety of customer requirements. Although the basic design of the assembly can usually be retained, for example, significantly different requirements with regard to the respective connection and the respective installation space, in particular for the absorber and an electrical machine, must be considered.
- the Assemblies can be individually designed to adhere to the respective minimum distances to other components by inserting individual spacer elements, which in turn require an individual unbalance compensation.
- One object of the present invention is therefore to provide an assembly for a hybrid drive train of a motor vehicle and a drive train, in particular a hybrid drive train, of a motor vehicle with an assembly that enables simple adaptation to individual axial distances and at the same time the assembly with regard to their imbalance is minimized.
- Another object of the present invention is to provide an alternative assembly for a hybrid drive train of a motor vehicle and an alternative drive train, in particular a special hybrid drive train, of a motor vehicle with an assembly.
- the present invention achieves the above-mentioned objects in an assembly for a hybrid drive train of a motor vehicle, comprising a first torque transmission device and a second torque transmission device connected to it in terms of torque, the first torque transmission device being arranged axially spaced from the second torque transmission device, and wherein the second torque transmission device has a smaller radial extent than the first torque transmission device and wherein in the radial direction above the second torque transmission device there is an installation space for a drive train.
- g device is specified in such a way that it is limited in the axial direction by the first torque transmission device,
- a distance device is arranged in the torque transmission path between the two torque transmission devices for axial spacing, which is designed so that an axially predeterminable minimum distance between the specified installation space and the first torque transmission device is maintained and that the distance device has a balancing device to compensate for an imbalance at least in the assembly.
- the present invention achieves the above-mentioned objects by a drive train, in particular a hybrid drive train, of a motor vehicle with an assembly according to one of claims 1-12.
- the spacing device enables, on the one hand, the balancing process, and, on the other hand, the spacing from other elements of the assembly in a simple manner by a single device.
- a simple and inexpensive production of the assembly or the drive train is thus possible, but at the same time also a high degree of flexibility with regard to the adaptation to the most varied of customer requirements.
- Another advantage is that an almost uniform manufacturing process for the assembly or the drive train is made possible.
- the spacer device is arranged in the radial direction below the installation space. This provides a compact installation space for the spacer device and an enlarged, predeterminable installation space for the drive train device provided.
- the spacer device extends in the radial direction between the first and second torque transmission device. This means that the space available for the assembly can be used efficiently without increasing it in the radial direction.
- the spacer device has an axial offset in the radial direction.
- the spacer device has at least one recess and / or one depression in the circumferential direction. In this way, an imbalance can be compensated for or compensated for by removing mass in a particularly simple manner.
- the spacer device is formed in the region of at least one recess for receiving an additional mass. In this way, an imbalance can be compensated or compensated for by an additional mass in a particularly simple manner.
- the at least one recess is designed to provide a clamp and / or clip connection.
- the spacer device has at least one separately arranged additional mass.
- An unbalance can thus be compensated for in a particularly simple manner by arranging an additional mass.
- the at least one vinmas se is U-shaped in cross section. This enables the additional compound to be easily introduced into a recess. In addition, due to the U-shape, a substantial part of the additional mass can be arranged further radially outwards, so that a higher mass moment of inertia can be provided.
- the at least one additional mass has a horizontal leg. On the one hand, this improves the handling of the additional mass when it is introduced into the recess, and on the other hand, more additional mass can be provided by the horizontal leg.
- the spacer device has an axial thickness that is constant over its radial extent. This enables simple production of the spacer device.
- At least one of the at least two torque transmission devices is designed as a damper.
- a vibration damping assembly can thus be made available.

- the spacer device then has an axial offset section 1b away from the absorber 2 and then again extends in the radial direction further outwards, parallel to the extension of the track plates 2b and the flyweights 2a of the absorber 2.
- the spacer device 1 points in Circumferential direction regularly to orderly recesses 4, introduced into the additional masses 5 and set therein Festge, for example by means of a clip connection.
- the Ausspa tion 4 not only an additional mass 5, but a further additional mass 5 can be arranged at the radially inner and outer ends. So that they do not slip during a rotary movement, a spacer can be arranged or introduced between the two additional masses 5.
- Figure 2 shows an additional mass according to an embodiment of the present invention.
- FIG. 1 an additional mass 5 for clipping into a recess is shown in FIG.
- the additional mass 5 is essentially U-shaped with two vertical legs 5a, 5c which are connected by means of a round leg 5b.
- the right vertical leg 5c has a horizontal leg at its upper end Projection or leg 5d.
- the additional mass 5 has inwardly extending projections on the edge side as part of a clip connection 6. These are intended to secure the additional mass 5 in the recess 4 against slipping.
