The angular travel of a washer 27,28.There are two washers 27,28 in the angular travel of this permission of each washer 27,28
The relative position of stacking, so that their in-profile is completely corresponding, as shown in Figure 10.
Figure 12 is the detail view of two washers 27,28 in the stacked position.Bullet is shown from the following perspective
One in spring washer 27 and its internal tooth 31, the above is one in friction washer 28 and its internal tooth 33, the internal tooth 31,33
It is stacked.The visible edge surface 38,39 of two internal tooths 31,33, which is located in identical transverse plane and is formed, to be intended to match with hub 3
The complementary drive surfaces of conjunction.
Figure 13 is shown above the stacking in Fig. 4 to be cooperated with hub 3.For the ease of reading figure, the profile of web 9 is with click and sweep
Line indicates that the profile of box 26 (behind web 9) is indicated with double dot dash line, and when two washers 27,28 are behind web 9, it is taken turns
Exterior feature indicated with chain-dotted line and when they not by web 9 cover when it is indicated by the solid line.
Figure 13 shows the profile of hub 3 and its interacts with the possibility for the other elements drawn.It can be seen that hub 3
The complementary shell 25 of shell 24 and web 9, but for simplicity, corresponding spring is not shown.Hub 3 is on its exterior contour
It further include the element between shell 24, for rotating driving washer 27,28 simultaneously.Rotary drive element is originally showing simultaneously for these
It include external tooth 40 in example, profile is complementary with the profile of internal tooth 31,33 of washer 27,28, enables external tooth 40 against above
Complementary drive surfaces described in reference diagram 12, according to plane to plane contact, therefore the edge surface of an external tooth 40 can be same
When drive two internal tooths 31,33, this is because their own complementary drive surfaces, and therefore can rotate driving two simultaneously
A washer 27,28.
Central torque-transfer members 3 include multiple driving elements 40 and multiple shells 24 for spring 41, are used for spring
41 shell 24 is circumferentially between driving element.For the axial arrangement of shell 24 and driving element 40 of spring 41, make
The plane existed perpendicular to rotation axis is obtained, which passes through the shell 24 for spring 41 and pass through center transmission member 3
Driving element 40.
In addition, the in-profile of web 9 includes receiving element, the receiving element is herein by 48 structure of tooth of angled setting
At so that also driving can be rotated by hub 3.
Figure 14 to 17 is the view for the greater proportion of Figure 13 of the Difference angles of hub 3, and shows the latter
A possibility that dynamic interaction between the other component of component.
Figure 14 shows such position, wherein hub 3 is rotated clockwise relative to web 9, directly since the position of Figure 13
It contacts to each external tooth 40 with washer 27,28, more precisely, is stacked until the first surface 46 and a pair of each external tooth 40
Internal tooth 31,33 contacts.The internal tooth 31 of spring washer 27 and the internal tooth 33 of friction washer 28 stack, the identical chain-dotted line table in Figure 14
Show the in-profile of elastic washer 27 and the in-profile of friction washer 28.
In the position of Figure 14, the first of the internal tooth 31,33 of the first surface 46 and washer 27,28 of each external tooth 40 is complementary
Driving surface 38,39 contacts, as shown in figure 12.
During the rotation from Figure 13 to Figure 14,41 (not shown) of spring is compressed, and washer 27,28 is relative to web 9
It is kept fixed.Therefore, friction washer 28 is not operated by rubbing come dissipation energy, and hub 3 is rotated by compressed spring 41
Drive web 9.
Since Figure 14, if the relative rotation of hub 3 along clockwise direction continues, internal tooth 40 rotates driving spring simultaneously
Washer 27 and friction washer 28.It is this at the same rotate the angle position for changing two washers 27,28 and without opposite between them
Movement.During rotating at the same time, friction washer 28 applies its energy dissipation function by the web 9 that rubs, and web 9 is by spring pad
Enclose 27 axially loaded, spring washer 27 is driven with identical rotation, is rubbed on box 26 in itself.
Rotation lasts are to the position of Figure 15 while washer 27,28, and wherein each external tooth 40 of hub 3 encounters the interior of web 9
Contouring.In the position, each first surface 46 of external tooth 40 abuts against the stacking of the internal tooth 31,33 of two washers 27,28
On first complementary drive surfaces, and also abut against on the tooth 48 of web 9.
From the position of the Figure 15, if the clockwise relative rotation of hub 3 continues, hub 3 no longer passes through spring 41
Compressible drive web 9, but it is directly driven by the Mechanical Contact of the first surface of external tooth 48 46 and the tooth of web 9.So
Afterwards, secondary damper no longer services, and only by the way that web 9 is arranged in and the main damper between washer 6,7 is guided to provide torsion
The damping of oscillation.
Hereafter, when secondary damper, which returns, to be serviced, more specifically, when hub 3 is rotated relative to web 9 in the counterclockwise direction
When, therefore hub 3 reaches any relative rotation of the position of Figure 16 without washer 27,28 relative to web 9 and box 26.Then,
Web 9 rotates drive hub 3 by compressed spring 41, without the movement of friction washer 28.
In Figure 16, each external tooth 40 of hub 3 is contacted with washer 27,28, more precisely, the second table of each external tooth 40
Face 47 is contacted with a pair of second complementary drive surfaces, and each second complementary drive surfaces are by one in the internal tooth 31,33 that stacks
Carrying.
Since Figure 16, if the relative rotation of hub 3 in the counterclockwise direction continues, internal tooth 40 rotates driving spring simultaneously
Washer 27 and friction washer 28.As previously mentioned, rotating the angle position for changing two washers 27,28 simultaneously and not having between them
There is relative motion.During rotating at the same time, friction washer 28 applies its energy dissipation function by friction web 9, web 9 by
Spring washer 27 is axially loaded, and spring washer 27 is driven with identical rotation, rubs on box 26 in itself.
Rotation lasts are to the position of Figure 17 while washer 27,28, and wherein each external tooth 40 of hub 3 encounters the interior of web 9
Contouring.In the position, the second surface 47 of each external tooth 40 is resisted against the stacking of the internal tooth 31,33 of two washers 27,28
On second complementary drive surfaces, and also against on the tooth of the in-profile of web 9 48.
From the position of the Figure 17, if the relative rotation in the counterclockwise direction of hub 3 continues, web 9 is connect by machinery
Touching directly drives hub 3, and secondary damper no longer services and only main damper works.
Therefore, the function of the friction washer 28 of secondary damper is obtained in reasonable time, i.e., in this example, according in pair
Damper it is deactivated before predetermined angular stroke.The angular travel does not have relative friction in friction washer 28 and spring washer 27
In the case where carry out, but friction washer 28 rubs on web 9 and spring washer 27 rubs on box 26.Therefore, washer 27,
28 are only driven in rotation in a part of the angular travel of hub, the friction function for being applied by friction washer 28 it is so-called
" sliding block " actuating power dissipates.
Under the exception that two washers 27,28 angularly slow down, such as due to impacting or vibrating, they will be in hub
The external tooth 40 for passing through hub 3 during 3 relative rotation relative to the web 9 that will be followed is quickly returned to its stacked position.Washer
27,28 relative rotation allows them to keep making an exception back to their stacked position and will not generate these washers
27,28 noticeable wear.
Since the system is related to according to its relative angular position rotary drive element, it is therefore necessary to by 26, two washers of box
