Abstract
The utility model relates to a torsion vibration damping mechanism. A plurality of bearing rings are provided to serve as preliminary vibration damping elements; the bearing ring is appressed with the lateral plane of external teeth of a spline shaft bushing along an axial direction by making use of a preliminary vibration damping disk-shaped spring; a plurality of axial convexities of the bearing ring are inserted into corresponding openings of a steel plate and a cover plate respectively; the structure and the fabrication process of the torsion vibration damping mechanism are both very simple, and the quantity of components is small, thus, the production cost can be reduced. In addition, the effect of the vibration damping and noise reduction is very obvious when an engine is in the operation with the idle speed proved by tests when the torsion vibration damping mechanism is used for automobile clutches.
Description
The utility model relates to a kind of torsion damping mechanism, more particularly, relates to the pre-damper mechanism of the torsion damping mechanism that is used for clutch driven plate.
At traditional torsion damping mechanism that for example is used for clutch driven disk for automobile, generally include main damper mechanism and pre-damper mechanism.When transmitting large torque, main damper mechanism works, and is transmitting under the situation of little moment of torsion (for example at engine idling operation time), and pre-damper mechanism works.Common pre-damper mechanism is by pre-shock-absorbing spring, pre-damping, and parts such as pre-vibration damping steel disc, pre-vibration damping axle sleeve plate and pre-vibration damping cover plate constitute.The requirement on machining accuracy of members such as pre-vibration damping steel disc wherein, pre-vibration damping axle sleeve plate and pre-vibration damping cover plate is than higher, and makes structure comparatively complicated, thereby is necessary to be simplified.
At the problems referred to above, the objective of the invention is to, provide a kind of structure and manufacturing process simple, thus the torsion damping mechanism that can reduce production costs.
For achieving the above object, the utility model provides a kind of torsion damping mechanism, comprising: a steel plate; One cover plate that fixes with described steel plate; At least one is installed in the friction plate of described steel plate outer circumferential side; One hub splines; The one axle sleeve plate that is meshed with described hub splines; At least one is fixed on the main shock-absorbing spring between described steel plate and the described cover plate vertically; At least one is arranged on the main damping spare of axle sleeve plate both sides; At least one is inlaid in pre-shock-absorbing spring in the notch between described hub splines and the axle sleeve plate by spring seat; At least one pre-damping spare is characterized in:
Described pre-damping spare is several bearer rings, and it is close to the outside flanks plane of hub splines vertically by pre-vibration damping belleville spring, and some axial projection of described bearer ring are inserted in respectively in the respective openings of described steel plate and described cover plate.
Structure and manufacturing process according to torsion damping mechanism of the present utility model are all fairly simple, and number of spare parts is few, thereby can reduce production costs.In addition, through evidence, when this torsion damping mechanism was used for automobile clutch, its vibration damping, noise reduction when engine idling operation was very obvious.
By more clearly understanding structural feature of the present utility model and purpose to the description of 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 Z part among Fig. 1, shows detail section wherein;
Fig. 3 is the partial view of seeing along arrow A direction among Fig. 1, the cooperation situation that shows hub splines, axle sleeve plate and be arranged on spring between the two.
See also Fig. 1 and Fig. 2, wherein show the torsion damping mechanism of the utility model one preferred embodiment, it mainly comprises: a steel plate 1; One cover plate 3 that fixes with steel plate 1; Be installed in several friction plates 5 of steel plate 1 outer circumferential side; One hub splines 7; The one axle sleeve plate 6 that is meshed with described hub splines 7; Be fixed on several the main shock-absorbing springs 8 between steel plate 1 and the cover plate 3 vertically; Be arranged on the main damping spare 4 of axle sleeve plate 6 both sides; Be inlaid in pre-shock-absorbing spring 9 in the notch between hub splines 7 and the axle sleeve plate 6 by spring seat 14; The axle sleeve ring 11 of being close to the external tooth both sides plane P of hub splines 7 by pre-vibration damping belleville spring 10 vertically as pre-damping spare.
In above-mentioned each member, the axle sleeve ring 11 in pre-damper mechanism, the 26S Proteasome Structure and Function of remaining part is identical with member commonly used in the past.
In addition, also show among the figure: be folded in the corrugated sheet 2 between the friction plate 5; Be used for installing the main vibration damping belleville spring 12 and the cross packing ring 13 of main damping spare 4; Spacing rivet 15; Friction plate rivet 16; Corrugated sheet rivet 17.Also all the member with commonly used in the past is identical for these parts, thereby repeats no more hereinafter.
Characteristics of the present utility model are, have adopted a kind of structure simpler, thereby the pre-damper mechanism that can boost productivity and reduce production costs, and it only is made up of pre-damping spare and pre-shock-absorbing spring two-part, and the number of components greatly reduces.
As shown in Figure 2, pre-damping spare is two bearer rings of being made by nylon 11, and some axial projection of this diaxon carrier ring 11 are inserted in respectively in the respective openings of steel plate 1 and cover plate 3.One pre-vibration damping belleville spring 10 is housed between steel plate 1 and bearer ring 11, and the axial force of its generation is close on the both sides plane P of hub splines 7 external tooths diaxon carrier ring 11.So, when steel plate 1, cover plate 3 and diaxon carrier ring 11 rotate together, can produce frictional damping moment by bearer ring 11 and relatively rotating of hub splines 7 external tooths two side planes.
As shown in Figure 3, pre-shock-absorbing spring 9 is cylindrical helical springs of several (there is shown two) symmetric arrangement, and they fixedly are inlaid in the notch between hub splines 7 and the axle sleeve plate 6 by spring seat 14.Between the teeth groove of the external tooth of hub splines 7 and axle sleeve plate 6 certain clearance is arranged, when axle sleeve plate 6 rotates, can compress pre-shock-absorbing spring 9 in this corner interstice coverage.
When transmitting little moment of torsion, for example under the situation of engine idling operation, in case the variation of fluctuation takes place in engine speed/moment of torsion, because of existing forward and reverse corner gap between hub splines 7 and the axle sleeve plate 6, so between hub splines 7 and the axle sleeve plate 6 relative rotation can take place, each pre-shock-absorbing spring 9 is compressed, and makes and produce frictional damping moment between the outside flanks plane P of diaxon carrier ring 11 and axle sleeve plate 6.Because the rigidity of each pre-shock-absorbing spring 9 and the frictional damping moment that the diaxon collar 11 is produced are all very little, so can allow the natural frequency of movement system be reduced to below the idling speed, thereby avoided the resonance of movement system when idling, the noise of speed changer when effectively reducing idling.
Although above detailed description has been made in a preferred embodiment of the present utility model, 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.For example, described bearer ring 11 also can be made with suitable resin material; If desired, it also is feasible only adopting a bearer ring 11.But the change of all these equivalences and conversion all should fall in the protection domain that is defined by the following claims.
