Description
Technical field
The utility model belongs to field of mechanical technique, is related to a kind of diaphragm spring.
Background technology
Diaphragm spring clutch be with diaphragm spring instead of general helical spring and separation linkage and make from
Clutch, because it is arranged in center, also central spring clutch finally.Diaphragm spring is made of one with thin steel spring plate
Carry certain taper, central part is provided with the cone shaped spring pieces of many uniformly distributed radial slots.
But its elasticity of existing diaphragm spring is general and stability is poor.
Invention content
The purpose of this utility model is in view of the above-mentioned problems existing in the prior art, to provide a kind of compact-sized and stability
High diaphragm spring.
The purpose of this utility model can be realized by following technical proposal：
A kind of diaphragm spring, which is characterized in that including ontology in the form of annular discs, the body central has perforative logical
Hole also has on the ontology and extends close to the v notch v in ontology edge, described v notch v end by through hole
With rounded deformation hole and deformation pore size is more than bar shaped gap width, and the quantity of above-mentioned v notch v is several and item
V notch v is circumferentially uniformly distributed centered on through-hole, one flaky shrapnel of formation between adjacent two v notch vs, on each shrapnel
With reinforcement structure.
This diaphragm spring creativeness makes shrapnel have favorable elasticity by deformation hole.Meanwhile in the effect of reinforcement structure
Under so that shrapnel is had sufficient intensity.
As can be seen that this diaphragm spring stability and intensity are relatively high.Simultaneously as it is integral structure, therefore,
Its structure is also compact.
In above-mentioned diaphragm spring, the ontology edge to through hole is inclined deformations, and above-mentioned shrapnel is located at shape
At change portion.
Shrapnel its elastic property at variant part is relatively good.
In above-mentioned diaphragm spring, the reinforcement structure includes the strengthening portion that shrapnel protrudes above.
It can be effectively increased intensity at shrapnel by strengthening portion.
In above-mentioned diaphragm spring, the strengthening portion protrudes from the inside of deformations, has on the outside of above-mentioned deformations and adds
The groove that strong portion matches.
Primary property strengthening portion can be processed by existing Sheet Metal Forming Technology on shrapnel.Certainly, groove is process
Remaining structure afterwards.
In above-mentioned diaphragm spring, all had on each shrapnel and its one-to-one strengthening portion.
In above-mentioned diaphragm spring, the strengthening portion is located at shrapnel center.
In above-mentioned diaphragm spring, the thickness of above-mentioned strengthening portion is the height gauge of the ontology edge to through hole
Very little 1/5-1/3.
In above-mentioned diaphragm spring, the strengthening portion in strip and all has fillet at the both sides of its end.
In above-mentioned diaphragm spring, there is a perforative deformation slot at the strengthening portion.
In above-mentioned diaphragm spring, the deformation slot, which is arranged in parallel with strengthening portion and deforms slot, is located at strengthening portion center
Place.
During large deformation occurs, strengthening portion energy progress strength buffering appropriate, has shrapnel under the action of deforming slot
Effect increases its stability, and the shrapnel in loading process is avoided to damage.
Compared with prior art, this diaphragm spring is on each shrapnel due to all having reinforcement structure, stability
It is relatively high.
Moreover, the diaphragm spring structure of integral structure is also compact, there is very high practical value.
Description of the drawings
Fig. 1 is the overlooking structure diagram of this diaphragm spring.
Fig. 2 is the schematic cross-sectional view of this diaphragm spring.
In figure, 1, ontology；1a, deformations；2, through-hole；3, v notch v；3a, deformation hole；4, shrapnel；4a, strengthening portion；
4a1, deformation slot.
Specific implementation mode
As depicted in figs. 1 and 2, this diaphragm spring includes ontology 1 in the form of annular discs, and 1 center of the ontology has perforative
Through-hole 2 also has on the ontology 1 and is extended close in the v notch v 3 of 1 edge of ontology by through-hole 2, and the bar shaped lacks
3 ends of mouth have rounded deformation hole 3a and deformation hole 3a sizes are more than 3 width of a v notch v, the number of above-mentioned v notch v 3
Amount is several and v notch v 3 is circumferentially uniformly distributed centered on through-hole 2, and it is flaky that one is formed between adjacent two v notch vs 3
Shrapnel 4 all has reinforcement structure 4a on each shrapnel 4.
It is inclined deformations 1a at the ontology 1 edge to through-hole 2, above-mentioned shrapnel 4 is located at deformations 1a.
The reinforcement structure includes the strengthening portion 4a that shrapnel 4 protrudes above.
The strengthening portion 4a is protruded from the inside of deformations 1a, is had on the outside of above-mentioned deformations 1a and to be matched with strengthening portion 4a
Groove.
It is all had and its one-to-one strengthening portion 4a on each shrapnel 4.
The strengthening portion 4a is located at 4 center of shrapnel.
The thickness of above-mentioned strengthening portion 4a is 1/5-1/3 of the height dimension at the ontology 1 edge to through-hole 2.
The strengthening portion 4a in strip and all has fillet at the both sides of its end.
There is a perforative deformation slot 4a1 at the strengthening portion 4a.
The deformation slot 4a1 and strengthening portion 4a, which is arranged in parallel and deforms slot 4a1, to be located at the centers strengthening portion 4a.
This diaphragm spring creativeness makes shrapnel have favorable elasticity by deformation hole.Meanwhile in the effect of reinforcement structure
Under so that shrapnel is had sufficient intensity.
As can be seen that this diaphragm spring stability and intensity are relatively high.Simultaneously as it is integral structure, therefore,
Its structure is also compact.
