Definitions
- the invention relates to a torsional vibration damper with at least one energy storage device, which has an input connected to a coupling device and a rotatable relative to the same against the action of at least one energy storage output and a rotation of the output relative to the input limiting rotational angle stop, and with a Tilgersystem, the at least one Tilgermassenlie has, which serves for receiving at least one relative to the same movable absorber mass, wherein the absorber mass carrier of the absorber system is effective as an output of the energy storage device.
- Such a torsional vibration damper is known from DE 10 2012 212 125 A1.
- This torsional vibration damper has two energy storage devices provided in series with one another, of which the energy storage device which is located on the drive side in the transmission direction of a torque transmitted by the coupling device is fastened with its input to a piston of the coupling device.
- the output of this at least one energy storage having energy storage device serves as Tilgermassenhov a Tilgersystems, and thus absorbs absorber masses relatively movable.
- the Tilgermassen39 is provided as well as the piston of the coupling device with recesses for receiving spacers, which are effective in conjunction with the recesses in each case as a rotational angle stop by limiting the Dreirlenkung the output relative to the input.
- the rotational angle stop is provided at a position of the energy storage device, which is located in the transmission direction of a torque transmitted by the coupling device behind the at least one energy storage.
- the torque load to be borne by the energy storage device of the energy storage device is limited to a predetermined limit torque by the rotational angle stop.
- the rotational angle stop does not bring any advantage.
- the absorber mass carrier has two Tilgermassenarmeiata arranged with axial offset from each other, one of which is provided with a radial guide and with a drive for at least one energy storage of a second energy storage device, and therefore serves as an input of this second energy storage device.
- the turbine wheel As the output of the second energy storage device, the turbine wheel is effective, which is connected to an output of the torsional vibration damper in the form of a non-rotatable with a transmission input shaft hub.
- the at least one energy store of the second energy storage device is arranged radially clearly outside the at least one energy store of the first energy storage device.
- the invention has for its object to form a Torsionsschwingungsdämpfer with a Tilgersystem such that the Tilgermassenarme and thus the absorber system when initiating a delivered via a coupling device torque that exceeds a predetermined limit torque, are loaded only by a torque which does not exceed the predetermined limit torque ,
- a torsional vibration damper with at least one energy storage device which has an input connected to a coupling device and a rotatable relative to the same against the effect of at least one energy storage output and a rotation of the output relative to the input limiting rotational angle stop, and with a Tilgersystem having at least one Tilgermassenlie, which serves to receive at least one relative to the same movable absorber mass, wherein the absorber mass carrier of the absorber system is effective as an output of the energy storage device.
- the rotational angle stop is provided at a position of the energy storage device, which is in the transmission direction of a torque transmitted by the coupling device in front of the at least one energy storage of this energy storage device, so that caused by the rotational angle stop limit of the Tilgermassen- carrier is ensured via the at least one energy storage torque supplied to a predetermined limit torque.
- the rotational angle stop comes into effect by the relative movement between the input of the energy storage device and its output, ie the Tilgermassenabo terminated, and thereby limits the relative movement in total. If it then comes to a further increase in the torque coming from the coupling device, then the effect of the rotation angle stop continues, so that even then only one of the predetermined
- Limit torque corresponding part of the torque is transmitted via the at least one energy storage to the output of the energy storage device and thus to the Tilgermassenstill. Since the rotational angle stop does not permit a transmission of a torque exceeding the limit torque, the portion of the torque coming from the clutch device beyond the limit torque must be conducted along another transmission path, and is therefore conducted directly to the output of the energy storage device before the at least one energy store, and from there to a downforce. Due to the above-mentioned positioning of the rotational angle stop relative to the at least one energy storage not only this energy storage is protected from an unduly high load, but equally the absorber mass carrier, since this is also exposed in the transmission of torques only torques that do not exceed the predetermined limit torque.
- the rotational angle stop thus positioned is particularly important if, in addition to a torque supplied by an internal combustion engine and possibly also by an electric machine, can occur, for example, during start-stop operations, recuperation processes or when sailing the corresponding motor vehicle with the internal combustion engine switched off.
- the angle stop In order for the angle stop to fulfill its function, it is structurally necessary for the output of the energy storage device in the transmission direction of a torque transmitted by the coupling device to be guided behind the absorber masses to the input of the energy storage device in order to attack there via the rotational angle stop at the input of the energy storage device.
- the previously discussed energy storage device is associated with a further energy storage device.
- the first-mentioned energy storage device would then act on the further energy storage device on the aforementioned output, which may be, for example, a standing in rotation with a transmission input shaft hub.
- the output of the first-mentioned energy storage device and thus the absorber mass carrier would be effective as an input of the at least one further energy storage device. Since at least one further energy storage device is assigned to the input of the at least one further energy storage device, there is an advantageous embodiment of this at least one further energy storage device, the input of this further energy storage device via at least one Drezirklenkung the output relative to the input limiting further angular position stop to the output.

- a rotational angle stop here in particular the further rotational angle stop for the further energy storage device is present when the input of the further energy storage device is formed by two cover elements, of which at least one as well as the output of the further energy storage device with recesses for receiving in each case at least one Spacer are provided which serves together with the recesses to form the further rotational angle stop.
- the further rotational angle stop is formed in the axial direction with a plurality of diameter steps, wherein cross-sectional transitions between the individual diameter steps form Axialstrom lake for each adjacent components.
- the cross-sectional transitions therefore allow axial positioning of individual components relative to one another.
- the at least one further energy storage device is provided radially inside the first energy storage device, while the input of the first energy storage device is guided into a radially outer region in which the at least one energy store of the first energy storage device is located.
- the absorber system of the present torsional vibration damper may be formed either with an absorber mass carrier, which is provided with two absorber mass carrier elements arranged with axial offset from one another and held at a fixed distance from one another by means of spacers, or else with an absorber mass. carrier having only a single absorber mass member.
- the two Tilgermassenhovetti take the at least one absorber mass axially between them, and only one of Tilgermassen39 implant is firmly connected to at least one of the cover elements of the input of the other energy storage device, while in the other embodiment, the individual Tilgermassenangeelement arranged axially between each other with axial offset Tilgermassen is provided, and is firmly connected by means of a connecting element with at least one of the cover elements of the input of the further energy storage device.
- the torsional vibration damper is shown below with reference to selected embodiments. It shows:
- FIG. 1 shows the torsional vibration damper with a Tilgersystem in which the Tilgermassenarme has axially spaced Tilgermassenträ- ger having axially at least absorb a damping mass between them, the Torsionsschwingungsdämpfer is accommodated in a housing of a wet-running starting element in the form of a hydrodynamic torque converter;
- FIG. 2 is an enlarged drawing of the torsional vibration damper according to FIG. 1;
- FIG. 2 is an enlarged drawing of the torsional vibration damper according to FIG. 1;
- Figure 3 is a plan view of the torsional vibration damper of Figure 2 according to the drawn in Figure 2 section line A -. A.
- Fig. 4 as shown in FIG. 2, but with a Tilgersystem, wherein the Tilgermassen39 has only a single Tilgermassenangeelement with absorber masses on both sides axially.
- the housing 2 has in the radially outer region on its inner side a toothing 4, in which a toothing 5 of drive-side coupling elements 6 rotatably engage.
- the drive-side coupling elements 6 can be brought into operative connection with the output side coupling elements 8 under the action of a piston 7, which are rotationally fixed by means of a toothing 9 with a toothing 10 of a toothed carrier 12 in engagement.
- the piston 7 is displaced to engage the coupling device 18 in the direction of the coupling elements 6 and 8, and presses them, generating a frictional force between the coupling elements 6 and 8 against a recessed into the teeth 4 of the housing 2 retaining ring 19, as soon as in a first pressure chamber 20, which is provided axially between a drive, not shown, such as an internal combustion engine, facing drive-side wall 21 and the piston 7, an overpressure against a second pressure chamber 22 is applied, which can act on the opposite side of the piston 7.
- a first pressure chamber 20 which is provided axially between a drive, not shown, such as an internal combustion engine, facing drive-side wall 21 and the piston 7, an overpressure against a second pressure chamber 22 is applied, which can act on the opposite side of the piston 7.
- the supply of the pressure chambers 20 and 22 takes place, inter alia, in a manner not shown in detail via flow channels 23 and 24 in the housing hub thirteenth
- the housing hub 13 serves to center a hub 25 of the torsional vibration damper 1 a, which serves as an output 26, and is non-rotatable with a transmission input shaft, not shown.
- a driven-side wall 28 of the housing 2 forms an impeller 30, shown only schematically, of the wet-running starting element 3, which interacts with a turbine wheel 31.
- an impeller 30 shown only schematically, of the wet-running starting element 3, which interacts with a turbine wheel 31.
- a likewise only schematically illustrated stator 32 is shown, which is centered on a freewheel 33, also shown schematically.
- the effective as part of the coupling device 18 gear carrier 12 is just like a torsional vibration damper 1 in Fig. 2 drawn out.
- the toothed carrier 12 and thus the coupling device 18 is connected by means of spacers 35 with an input 36 of the torsional vibration damper 1, with axial distance between the coupling device 18 and the input 36.
- the spacers 35 are provided with a formed axial middle portion 37 which has a larger diameter than the axial end portions 38a, 38b. With this axial middle part 37, the respective spacer 35 passes through recesses in two abutting cover elements 39, 40, wherein these recesses 41, as shown in FIG. 3, extend further in the circumferential direction than with respect to the diameter of the axial middle part 37 of the respective spacer 35 would be required.
- the recesses 41 therefore afford the spacers 35 a relative deflection in the circumferential direction, so that a relative rotational displacement is also possible between the coupling device 18 and the input 36 of the torsional vibration damper 1 on the one hand and the two cover elements 39, 40 on the other hand.
- This relative deflection can continue until the middle part 37 of the respective spacer 35 comes into contact with one of the peripheral end edges 77 of the respective recess 41 (FIG. 3).
- the spacers 35 thus act together with the respective recesses 41 as rotational angle stop 42.
- the input 36 of the torsional vibration damper 1 engages, starting from its attachment point to the coupling device 18, radially outward, and has a control 44 for at least one energy storage 45 of a first energy storage device 46.
- the at least one energy storage 45 is based on the other side on a AbSteutation 47th which is attached to a driven-side Tilgermassen 1985element 48 a Tilgermassenconces 49 by means of a riveting 50.
- the output-side Tilgermassenarmeelement 48 continues to take by means of this riveting 50 a radial guide 51 for the at least one energy storage 45.
- the output side Tilgermassenhowelement 48 is connected to form the Tilgermassenarmes 49 in its radially inner region via spacers 52 with a drive side Tilgermassenarmeelement 53 which is rotatably held by the spacer 52 and at a fixed axial distance to the output side Tilgermassen 1985element 48.
- absorber masses 74 are received in a relatively movable manner relative to the absorber mass carrier elements 48 and 53, and together with these form a damper system 55.
- the drive-side Tilgermassenarmeelement 53 is radially within the spacer 52 by means of further spacers 54 on the output-side cover member 40 of the aforementioned cover elements 39, 40 attached.
- This output-side cover element 40 is fixedly connected to the drive-side cover element 39 by means of the further spacers 54.
- the two cover elements 39, 40 are effective together with the Tilgermassenlasi 49 as the output 56 of the first energy storage device 46.
- the two cover elements 39, 40 simultaneously serve as input 57 of a second energy storage device 58, and therefore have at least one energy store 60 in energy storage windows 59, which are also shown in FIG. 3.
- the at least one energy storage 60 is supported in the circumferential direction with one end on a drive 73, which are formed by the peripheral end edges of the energy storage window 59, and with the opposite in the circumferential direction End at an AbSteutation 61 of an output 62 of the second energy storage device 58 from.
- This output 62 is fastened by means of a riveting 63 on the hub 26 serving as the output 26 of the torsional vibration damper 1.
- the already mentioned further spacers 54 are formed with an axial middle part 65, which has a larger diameter than the axial end regions 66a, 66b.
- this axial middle part 65 With this axial middle part 65, the respective spacer 4 passes through recesses in the two abutting cover elements 39, 40, wherein these recesses 67, as shown in FIG. 3, extend in the circumferential direction further than this with respect to the diameter of the axial Central portion 65 of the respective spacer 54 would be required.
- the recesses 67 therefore afford the spacers 54 a relative deflection in the circumferential direction, so that a relative rotational displacement is also possible between the two cover elements 39, 40 on the one hand and the output 62 on the other hand.
- the spacers 54 thus act together with the respective recesses 67 as rotational angle stop 68.
- the turbine wheel 31 shown in FIG. 1 may alternatively be fastened either to the driven-side absorber mass support element 48 via the spacers 52 or to the hub 25 and thus to the output 26 via the riveting 63.
- the hub 25 on the drive side is supported on the housing hub 13 and on the output side via the output-side cover element 40 and the drive-side Tilgermassenmbaelement 53 via an axial bearing 70 on the freewheel 33 from.
- the torsional vibration damper 1 a of FIG. 1 differs in two details from the torsional vibration damper 1 shown in FIG. 2:
- the drive-side cover element 39a ends according to FIG. 1 radially directly outside of the at least one energy store 60 of the second energy storage device 58, so that only the output-side cover element 40 engages axially between the toothed carrier 12 and the input 36 of the first energy storage device 46. Since the output-side cover element 40 but unchanged in the 1 to the penetration of the spacer 38, the function of the torsional vibration damper 1a shown in FIG. 1 does not change in comparison with the torsional vibration damper 1 from FIG. 2.
- FIG. 1 has spacers 54a for the second energy storage device 58 which are axially multi-stepped to replace the spacers 54 shown in FIG. 2 at this point as well as the riveting 63 provided radially inside these spacers 54.
- the axial Mehrstuf ig speed is achieved by provided in the axial direction diameter steps 71, 72, wherein cross-sectional transitions between the individual diameter stages 72, 72 Axialstrom lake for the two cover elements 39, 40 form.
- the torsional vibration damper 1 b shown in FIG. 4 basically corresponds to the torsional vibration damper 1 shown in FIG. 2, but has differences in the design of the absorber system 55 b. Accordingly, the absorber mass carrier 49b only has a single absorber mass carrier element 75, which absorbs damper masses 74 relatively movably on both sides. This absorber mass carrier 49b is connected via the spacers 52b to a connection flange 76, which in turn acts via the spacers 54b on the cover elements 39 and 40 and thus at the output 56b of the first energy storage device 46b or at the input 57b of the second energy storage device 58b.
- a torque supplied via the toothed carrier 12 of the coupling device 18 is transmitted via the spacers 35 to the input 36 of the first energy storage device 46.
- the input 36 is supported by its control 44 at the adjacent end of the at least one energy store 45 under deformation thereof, since the at least one energy store 45 is supported on the take-off 47 with its other end facing away from the control 44, and the Is attached to the output side Tilgermassenmbaelement 48 control, the torque reaches the Tilgermassenträ- gerelement 48 and thus, since this is connected via the spacers 52 with the drive-side Tilgermassenexcellentelement 53, also on this absorber mass carrier element.
- the torque is transmitted to the adjacent end of the at least one energy storage device 60 of the second energy storage device 58 by deformation of the at least one energy storage device 60 via the drive 73 corresponding to the effective direction. Since the at least one energy store 60 is supported with its other end facing away from the control 73 at the Abêtung 61, and the Abêtung 61 is provided at the output 62 of the second energy storage device 58, the torque passes due to the attachment of the output 62 of the second energy storage device 58th on the hub 25 of the output 26 to the output 26, and from there to a transmission input shaft, not shown.
- torsional vibrations or even shocks are superimposed on the torque supplied via the toothing carrier 12 of the coupling device 18, then these lead to a temporary increase or reduction in the at least one energy store 45 of the first energy storage device 58 or of the at least depending on the effective direction of the torsional vibrations or shocks an energy storage 60 of the second energy storage device 58 torque applied.
- the torsional vibrations or the impacts cause a deflection of the absorber masses 74 relative to the absorber mass carrier elements 48 and 53 and thus of the mass damper carrier 49 at least substantially in the circumferential direction.
- the first energy storage device 46 associated rotational angle stop 42 is effective to avoid damage to the at least one energy storage 45.
- the rotational angle stop 42 associated with the at least one energy store 45 of the first energy storage device 46 the axial middle part 37 of the spacer 35 then comes to rest against the end edge 77 of the recess 41 (FIG. 3) assigned to the effective direction of the torque.
