Specific embodiment
Fig. 1 shows above the torque converter 1 that the rotation axiss d around transmission input shaft 6 torsionally arranges
Part.Housing 14 receives pump impeller 3, turbine 10, changer bridging clutch 9, centrifugal force pendulum 4 and torsional vibration damper 13, and
And filled with hydraulic fluid at least in part in run duration, couple with the fluid dynamic of turbine 10 for setting up pump impeller 3.
Housing 14 by fastening means 15, by flexible board or such bent axle with internal combustion engine without relative rotation
And axial elasticity ground connects.Pump impeller 3 is integrated in housing 14.Housing 14 by torque converter shell 16 and has axial elongation portion
18 wall 17 is constituted, and described shell and wall are in radially outer connection sealed to each other, for example weld.Changer bridging clutch 9 is integrated
To in turbine 10 and pump impeller 3.For this reason, turbine 10 is radially widened and is had clutch bead 19.In torque converter shell 16
And axial elongation portion 18 welding elongated portion 21 and described pump impeller 3 between transition part on be provided with ring region section 20.In clutch
Setting friction facing 22, such as paper liner in device bead 19 and/or in ring region section 20, this friction facing and changer bridge from
The corresponding rubbing surface of clutch 9 constitutes frictional fit.Changer bridging clutch 9 is by the fluid between one side chamber 23 and chamber 25
Operating, described chamber 23 is enclosed between turbine 10 and pump impeller 3 stream, and described chamber 25 is by transmission input shaft 6 and turbine 10
Between bushing 24 separate with described chamber 23, wherein, described fluid stream passes through the hollow hole of gap 26 and transmission input shaft 6
27 import and derive.Described fluid stream flows through chamber 23,25 with the different flowing velocities of turbine 10, thus turbine obtains buoyancy
And be opened (Auftrieb).Described fluid stream maintains especially when changer bridging clutch 9 is opened and skids.With outstanding
Its favourable mode arranges groove, such as cooling bath in friction facing 22 and/or in the corresponding rubbing surface of this friction facing, described
Groove also maintains predetermined fluid stream and then cools down changer in the region of frictional fit when changer bridging clutch 9 closes
Bridging clutch 9.
Centrifugal force pendulum 4 is arranged between wall 17 and turbine 10 in chamber 25 in the axial direction, and substantially occupy radially can
Space is until the inner circumferential in axial elongation portion 18.Centrifugal force pendulum 4 is used as the output of torque converter 1, and has distribution
Pendulum element 29 on periphery and pendulum element bearing part 30.Pendulum element bearing part 30 is made up of two diskwares 31,32, described diskware
Interconnect by rivet 33 in inner radial.Carrying section 34 Anti-fall respectively constituting in the radially outer of described rivet 33
Ground receives the pendulum element 29 arranged to distribution on periphery.Diskware 31 is directed to each pendulum element 29 in radially outer and has a pendulum
Roller track 35, the periphery of pendulum element 29 is supported under the action of the centrifugal force on this pendulum roller track and twisting vibration
When roll.Here, the make of the such as arc in circumferential direction according to pendulum roller track 35, pendulum element 29 is against centrifugation
Power be displaced to less diametrically, thus torque peak kinetic energy conversion and intermediate storage be potential energy in the case of make torque
Change curve smooths.Diskware 31 is used for putting the axial relief of element 29, described pendulum element be arranged substantially at changer bridge from
In the radial height of clutch 9.Pendulum element 29 spherically constructs in the contact area with respect to pendulum roller track.Diskware 31,
Between 32, gap 36 is set in radially outer, to improve the dynamic (dynamical) fluid guiding for example put on element 29.
Additionally, two diskwares 31,32 are constituted for putting the axially directed of element 29.In order to avoid in described diskware 31,32
A diskware and the end face 50 of pendulum element between axial plane position state so that put high friction during element 29 rolling movement, pendulum
Element spherically constructs.It means that pendulum element 29 has the axial width of maximum on its rotation axis D.By this way,
All the time the only less part of whole end face 50 is in abutting contact with diskware 31,32, thus friction and then pendulum element 29 phase
Breakaway (Losbrechkraefte) for diskware 31,32 reduces.
Hub 5 is connected cohesively together, for example, engages and receive centrifugation with the end regions rotation of the side of transmission input shaft 6
Power pendulum 4.For this reason, diskware 31 to receive by identical rivet 38a in the radially expanded hub bead 38 of hub 5, such as optional
The output 37 of torsional vibration damper 13 is such.The output 37 of torsional vibration damper 13 and by rivet 40 and turbine 10
Spring element 41 that the input component 39 connecting is arranged with resisting on periphery distribution, the effect of such as helical compression spring with respect to
Can reverse around rotation axiss d each other, thus torsional vibration damper 13 makes remaining torsional vibration damper, this remaining torsion
After the Hydraulic coupling that rotational oscillation moves between pump impeller 3 and turbine 10 and still remaining by the damping effect of turbine type mass.Connection
Followed centrifugal force pendulum 4 makes still remaining torsional vibration damper after torsional vibration damper 13 again.
The supporting that torsional vibration damper 13 radially, economical space saving receives in this turbine on transmission input shaft 6
Moving back in turbine 10 between the domed portion (Bauch) that the maximum axial with thin slice (Lamellen) 43 of portion and this turbine is widened
In the region in contracting portion (Einzugs).Here, input component 39 be arranged as spring element 41 diameter outside around this spring element
Part at least overlaps the overall diameter of this spring element, thus this spring element radial direction is supported ground and axially anti-lost land reception and exist
In input component 39.
For integrity it should be mentioned that arranging guide wheel 46 between pump impeller 3 and turbine 10, in the case of speed discrepancy
Torque improves, and this guide wheel receives in guide wheel female connector 48 by freewheel 47.
Fig. 2 shows that the centrifugal force pendulum 4 of Fig. 1 sees pendulum element 29 and pendulum element bearing part in the case of taking off diskware 31
Partial view on 30 diskware 32.Axial elongated portion 43, structure in the inner circumferential of this elongated portion are shaped on the periphery of diskware 32
Make the pendulum roller track 35 for putting element 29.Pendulum roller track 35 shape in circumferential direction predetermined pendulum element 29 is turning
Pendular motion in centrifugal force field under the influence of square vibration.In the illustrated embodiment, pendulum element 29 can be turned round around rotation axiss D
Turn ground circularly to constitute.Described pendulum element also can be configured to other shapes, such as ellipse, water-drop-shaped and such shape
Shape.By putting shape, pendulum element 29, the quality of pendulum element and one or more vibration of such setting of roller track 35
Level.By the wheel rim 44 of axially broadening in the inner circumferential of diskware 32, pendulum element 29 is with respect to the diagram drawn up respectively
It is maintained in the region of its pendulum roller track 35.The end face 50 of pendulum element 29 spherically constructs.
Fig. 3 shows the centrifugal force pendulum 4 of Fig. 1 and 2 with cross-sectional detail.Diskware 31,32 is in carrying section 34 in the face of pendulum
Flat abutment face 51 is provided with the side of element 29.Pendulum element 29 has radius R on its end face 501, thus with respect to patch
This abutment face 52 by face 51 constructs the area less than end face 50.Here, radius R1Periphery in rotation axiss D and pendulum element
Between set spacing a.
Fig. 4 shows, with cut-away section, the centrifugal force that the centrifugal force pendulum 4 with respect to Fig. 1 to 3 changes in the diagrams of figure 3
Pendulum 4a.Different from centrifugal force pendulum 4, the end face 50a putting element 29a flatly constructs.In order to reduce the end with respect to pendulum element 29a
