Adopted a pre-vibration damping control piece to control pre-vibration damping in the torsion damping mechanism of the present utility model, replaced the flange of the sort of and hub spare that in the past adopted to be meshed, the intermediate plate higher to requirement on machining accuracy, thereby provide the good twisting damping property when can and reduce production costs in simplified structure and manufacturing process.This torsion damping mechanism can be used for the clutch drived disk assy of mechanical clutch, and the moment of torsion that also can be widely used in other mechanical industry transmits occasion.
By more clearly understanding structural feature of the present utility model and purpose to the description of the utility model preferred embodiment below in conjunction with accompanying drawing.
Fig. 1 is a sectional view, shows the torsion damping mechanism of the utility model one preferred embodiment;
Fig. 2 is the zoomed-in view of K part among Fig. 1, shows detail section wherein;
Fig. 3 be with the torsion damping mechanism among Fig. 1 get rid of a part of back from A to the view of seeing, show each elastic element and hub spare and reach mated condition between the pre-vibration damping control panel.
See also Fig. 1 and Fig. 2, wherein show the torsion damping mechanism of the utility model one preferred embodiments, it mainly comprises a steel plate 5; One cover plate 7 that fixes with steel plate 5; Be installed in a plurality of friction plates 3 of described steel plate 5 outer circumferential sides; One has the hub spare 17 of center bump 171 and peripheral outer lips 172, is formed with four small gap 172a and decentre four big breach 172b (as shown in Figure 3) far away near the center on the described flange 172; Be fixed between steel plate 5 and the cover plate 7 vertically and be in four main shock-absorbing springs 8 in both the corresponding fenestra; The spacing rivet 6 that is used for main shock-absorbing spring 8; The pre-vibration damping control piece of forming by a control panel 12 and retaining plate 13 thereof; Be installed in four pre-shock-absorbing springs 14 between control panel 12 and the retaining plate 13 vertically; Be separately positioned on two main damping sheets 10 in the control panel 12 and retaining plate 13 outsides; Be arranged on the pre-damping sheet 15 between flange 172 and the control panel 12.
As shown in Figure 1, steel plate 5 is discoid members, and it fixes by rivet 6 and cover plate 7.The outer circumferential side of steel plate 5 is provided with a plurality of friction plates 3, and they are provided with corrugated sheet 1 therebetween by rivet 2 riveted fixing, and corrugated sheet 1 is fixed in steel plate 5 by rivet 4.Main shock-absorbing spring 8 is to be fixed between steel plate 5 and the cover plate 7 vertically and to be in both corresponding fenestras, and they can tangentially stretch, and plays the effect of vibration damping with main damping spare coupling.The rigidity of main shock-absorbing spring 8 is bigger.It is spacing that 6 pairs of main shock-absorbing springs 8 of rivet flexible play a part.Hub spare 17 is power output elements, wherein is provided with spline tooth in the endoporus of heart bump 171 to engage transferring power with output shaft.
These above-mentioned structures are identical with traditional torsion damping mechanism that is used for clutch driven plate, characteristics of the present utility model are, it has used a pre-vibration damping control piece to control pre-shock-absorbing spring, and then be pre-damping spare, the flange of the sort of and hub spare that therefore can eliminate in the past to be adopted is meshed, the intermediate plate higher to requirement on machining accuracy, thus the purpose that reaches simplified structure and technology and reduce cost.
As shown in Figures 1 to 3, pre-vibration damping control piece is made up of a control panel 12 and a retaining plate 13, rivet mutually between this two member so can not rotate mutually, pre-shock-absorbing spring 14 is to be fixed between control panel 12 and the retaining plate 13 vertically and to be in both corresponding fenestras, they also can tangentially stretch, and play the effect of vibration damping with pre-damping spare coupling.The rigidity of pre-shock-absorbing spring 14 is less.Be formed with four on the flange 172 of hub spare 17 near the breach 172a at center, pre-shock-absorbing spring 14 is in this four breach first.There are two grooves the periphery of pre-vibration damping control panel 12, these two two ends that groove blocks two main shock-absorbing springs 8 respectively.Between side of the flange 172 of hub spare 17 and pre-vibration damping control panel 12, pre-damping sheet 15 is housed, between the opposite side of flange 172 and retaining plate 13, a corrugated sheet 16 is housed.
A main damping sheet 10 respectively is equipped with in the outside at pre-vibration damping control panel 12 and retaining plate 13.In the outside of a damping fin 10 cross packing ring 11 is housed, the finger tongue portion of packing ring 11 is inserted in the hole of steel plate 5, between packing ring 11 and the steel plate 5 spring 9 is housed, and can not relatively rotate between packing ring 11 and the steel plate 5 but can move axially relatively.The outside of another damping fin 10 contacts with cover plate 7.
In addition, main shock-absorbing spring 8 also in the decentre of the flange 172 of hub spare 17 breach 172b far away, for a change, leaves certain clearance between the both ends of the surface of spring 8 and the side of breach.Will describe in detail hereinafter, this gap control the phase angle of pre-damping assembly.
To describe the working condition of the torsion damping mechanism of the utility model one preferred embodiment below in detail.
When clutch was worked, under the situation of transmitting little moment of torsion, power imported into from friction plate 3, imports main shock-absorbing spring 8 into through steel plate 5, cover plate 7.Because the rigidity of main shock-absorbing spring 8 is bigger, thus it be compressed hardly, at this moment still gapped between the sidewall of the breach 172b of spring 8 and hub spare flange 172.Then, power passes to pre-vibration damping control panel 12 and retaining plate 13 through spring 8, at this moment can regard control panel 12, retaining plate 13 and steel plate 5, cover plate 7 as one.Follow, power imports pre-shock-absorbing spring 14 into by pre-vibration damping control panel 12, retaining plate 13 again, and the effect of mat spring 14 and pre-damping sheet 15 reaches hub spare 17.That is, under the situation of transmitting little moment of torsion, pre-shock-absorbing spring 14 pressurizeds, pre-damping sheet 15 works; Main shock-absorbing spring 8 not by compression, main damping piece 10 is inoperative.Wherein, the relative rotation of pre-vibration damping control panel 12, retaining plate 13 and 17 of hub spares, just the phase angle of vibration damping is determined by the gap between the side of the breach 172b of spring 8 and hub spare flange 172 in advance.
Under the situation of transmitting large torque, power imports into from friction plate 3, imports main shock-absorbing spring 8 into through steel plate 5, cover plate 7.After having turned over certain angle (eliminating the gap of spring 8 and hub spare 17) between steel plate 5 and the hub spare 17, main shock-absorbing spring 8 is compressed.In case main shock-absorbing spring 8 by compression, pre-vibration damping control panel 12, retaining plate 13 just no longer relatively rotate with hub spare 17.That is, pre-shock-absorbing spring 14 no longer continues pressurized, and the pre-damping sheet 15 that control panel 12 and hub spare are 17 no longer works.At this moment, can relatively rotate between steel plate 5, cover plate 7 and pre-vibration damping control panel 12, retaining plate 13, the hub spare 17, main shock-absorbing spring 8 pressurizeds, main damping fin 10 works.
Although above detailed description has been made in a preferred embodiment of the present utility model; but it should be understood that; person skilled in the art can also make the change and the conversion of all equivalences on the basis of not departing from essence of the present utility model and spirit, the change of all these equivalences and conversion all should fall in the protection domain of the present utility model.
