Damping fin 50 between hub plate 30 and driven disc ontology 20；
Between damping disk(-isc) 10 and hub plate 30, two annular damper pieces 41 being set in Plate hub core 31, two
Damping fin 41 is used as frictional damping assembly.One of damping fin 41 is torsionally fixedly connected with damping disk(-isc) 10, another damping
Piece 41 is torsionally fixedly connected with hub plate 30.
As shown in connection with fig. 6, damping fin 41 includes two opposite annular surfaces, respectively surface S1, surface S2；And
Outer ring side S3 and inner ring side S4.With reference to shown in the region Q in Fig. 6, the region Q is that the region P is looked over from inner ring side S4
Side view, the surface S1 of damping fin 41 have a lug boss 400 that flexible deformation can occur, and lug boss 400 has from top the bottom of to
The portion slope surface S5 that (i.e. direction shown in arrow A in figure) extends along circumferential direction.The slope surface S5 of lug boss 400 is inclined-plane, lug boss
400 top and bottom are plane S6, and plane S6 is perpendicular to the axis of damping fin 41.
In the present embodiment, the surface S2 of damping fin 41 has the recess portion (not identifying) for concaving towards lug boss 400, and surface S2
Parallel in corresponding position with surface S1, so that the surface S2 of damping fin 41 also has lug boss (not identifying), and surface S2's is convex
The position risen between portion and two circumferentially adjacent lug bosses 400 of surface S1 is corresponding.
In the present embodiment, two damping fins 41 have surface S1 contact and the mutual extrusion of lug boss 400.In this implementation
In the alternative of example, it is also possible to surface S1 of the damping fin 41 with lug boss 400 and another damping fin 41 with described
The surface S2 of lug boss is contacted and mutual extrusion；Alternatively, being also possible to the surface S2 that two damping fins 41 have the lug boss
Contact simultaneously mutual extrusion.
In conjunction with shown in Fig. 6, Fig. 7 and Fig. 8, in the present embodiment, there are four identical and along week for the surface S1 of damping fin 41 tool
To the lug boss 400 being spacedly distributed.So, the damping fin 41 of the present embodiment can pass through following very simple method
Manufacture: being initially formed the general structure of damping fin 41, and in the general structure of damping fin 41, its two annular surfaces are mutually flat
Capable plane；Then, four lug bosses 400 being circumferentially spacedly distributed are formed using Sheet Metal Forming Technology.
In conjunction with shown in Fig. 9, Figure 10 (a), Figure 10 (a) is indicated: clutch driven plate original operating state is (driven with clutch
Disk waits for that work state is identical) under, the relative positional relationship rough schematic view between two damping fins.In the present embodiment, clutch
Driven disc waits under work state (i.e. two damping fins 41 do not start to relatively rotate), the surface S1 of a damping fin 41 and another damping
The surface S1 of piece 41 is seamless to fit together.
In conjunction with shown in Fig. 9 and Figure 10, wherein Figure 10 (b) is indicated: when two damping fins are relatively rotated to a certain angle, two
Relative positional relationship rough schematic view between a damping fin；Figure 10 (c) is indicated: two damping fins relatively rotate to two dampings
Relative positional relationship rough schematic view when the top initial contact in piece protrusions portion, between two damping fins.The present embodiment
When clutch driven plate works, two damping fins 41 are as follows as the course of work of frictional damping assembly:
Two damping fins 41 can relatively rotate.Specifically, the lug boss 400 in a damping fin 41 can be from another damping fin
Interval location in 41 between two neighboring lug boss 400 starts, according to direction shown in arrow B in figure, along another resistance
The slope surface S5 in 41 protrusions portion 400 of Buddhist nun's piece is mobile.Under the mutual extrusion effect of two damping fins 41, in two damping fins 41
Lug boss 400 can be axially pressed, and apply forces against each other and occur flexible deformation, the resistance relative to not lug boss
Buddhist nun's piece, the mutual extrusion between two lug bosses 400 can increase the friction between two damping fins 41.
It being gradually increased as two damping fins 41 relatively rotate angle, the top of two damping fins 41 moves closer to, and two
The deformation extent in 41 protrusions portion 400 of damping fin is gradually increased.As shown in Figure 10 (c), when two 41 protrusions portions 400 of damping fin
Top initial contact when, the deformation extent in two 41 protrusions portions 400 of damping fin increases to maximum value, so that two damping fins
41 pressure applied each other also increase to maximum value.
In Figure 11, positioned at reference axis first quartile curve indicate driven by engine gearbox rotation when, clutch from
The characteristic curve of Moving plate；When indicating that gearbox drives engine rotation positioned at the curve of reference axis third quadrant, clutch is driven
The characteristic curve of disk.As shown in figure 11, when clutch driven plate works, frictional damping square meeting caused by clutch driven plate
Increase as two damping fins 41 relatively rotate the increase of angle.Since the slope surface S5 of lug boss 400 is inclined-plane, therefore at two
When damping fin 41 relatively rotates, the pressure that two damping fins 41 apply each other, with the relative rotation angles of two damping fins 41 it
Between theoretically linear variation relation so that frictional damping square produced by clutch driven plate, with relatively rotate angle it
Between theoretically linear variation relation.
As the above analysis, the clutch driven plate of the present embodiment relies on damping fin 41 itself, that is, can reach increase resistance
The purpose of friction between Buddhist nun's piece component adjacent thereto, simplifies the structure of frictional damping assembly.Due to frictional damping assembly
Structure is simplified, therefore can not only reduce the cost of clutch driven plate, but also can reduce clutch driven plate
Rotary inertia, and then impact suffered when automobile gear shift can be reduced.
In addition, since two damping fins 41 are in the course of work, two 41 pressures of damping fin not instead of constant, with
The difference of angle is relatively rotated, pressure can change, therefore frictional damping is away from being also not constant, therefore, clutch driven plate
Adjustment when generated frictional damping square can put into effect according to the damping requirements of traveling road conditions, can obtain good NVH performance.
In other embodiments, the slope surface S5 of lug boss 400 may be cambered surface.It is also possible to two tables of damping fin 41
In face S1, S2, only surface S1 has lug boss 400, and surface S2 is plane.In this case, clutch driven plate is produced
Raw frictional damping square can still increase as two damping fins 41 relatively rotate the increase of angle, only in this feelings
Under condition, no longer linear variation relation between frictional damping square produced by clutch driven plate, with relative rotation angle.
It in the present embodiment, is that there are four for lug boss 400 to set in damping fin 41.In fact, can on damping fin 41
The lug boss 400 of one or more is arranged.When damping fin 41 is equipped with multiple lug bosses 400, the structure of each lug boss 400
Can not be identical, multiple lug bosses 400 can also circumferentially unequal interval distribution.
When multiple circumferentially distributions of unequal interval of lug boss 400, clutch driven plate can be made to wait under work state, two
Any two lug boss 400 of a damping fin 41 does not contact.In this case, it is relatively rotated in two damping fins 41, two
Before 400 initial contact of lug boss of a damping fin 41, frictional damping square caused by clutch driven plate is constant.Then,
It is gradually increased as two damping fins 41 relatively rotate angle, 400 mutual extrusion of lug boss of two damping fins 41, so that clutch
Frictional damping square caused by device driven disc is gradually increased.
When changing the quantity in 41 protrusions portion 400 of damping fin, two dampings when adjustable frictional damping assembly works
The size that piece 41 applies forces against each other: when the quantity of lug boss 400 is more, elastic change can occur for more lug bosses 400
Shape keeps the pressure bigger；When the quantity of lug boss 400 is fewer, the pressure is smaller.
When changing the overhead height in 41 protrusions portion 400 of damping fin, two when adjustable frictional damping assembly works
The size that damping fin 41 applies forces against each other: when the top of lug boss 400 is higher, there is lug boss 400 bigger elasticity to become
Shape ability can make the pressure bigger；When the top of lug boss 400 is lower, the pressure is smaller.
Therefore, by adjusting the structure of damping fin 41, adjustable 41 pressure of damping fin, and then adjustable clutch
Frictional damping square produced by device driven disc enables the maximum value of frictional damping square to be greater than the prior art, with a greater degree of
Improve the effectiveness in vibration suppression of clutch driven plate.
