Description
Technical field
The utility model belongs to clutch accessory technical field, is related to a kind of diaphragm spring, more particularly to a kind of clutch
Use diaphragm spring.
Background technology
Diaphragm spring, also referred to as diaphragm disc spring, grooved disk spring.As the so-called diaphragm spring of holddown spring, it is
It is rammed by spring steel, the truncated cone shape thin-walled diaphragm with bottomless plate shape, and many is provided with the conical surface from its small end
Radially slotted, to form elastic lever, and the big end truncated cone part of remaining non-grooving then plays spring effect.Diaphragm spring is clutch
The part of most critical in device, plays and the effect such as thrust and cut-out power, overload protection is produced to platen.Existing diaphragm spring
Integral thickness it is consistent, the low intensity of separation finger, the structure of diaphragm spring is not sufficiently stable, accelerate diaphragm spring wear intensity and
Service life, reduces the service life of clutch.
The content of the invention
The purpose of this utility model is there is above mentioned problem for existing technology, it is proposed that a kind of clutch diaphragm bullet
Spring, it has higher structural strength and longer service life.
The purpose of this utility model can be realized by following technical proposal：A kind of diaphragm spring for clutch, including system
For the dish-shaped body and the round hole positioned at dish-shaped body central of annular, several edges are evenly distributed with the dish-shaped body
Radially slotted and several separation fingers of the radially uniform setting of round hole, each separation finger is respectively positioned on two adjacent radial directions and opened
Between groove, it is characterised in that the top of the separation finger has rib of the bending in circular arc, the bottom both sides of separation finger are equal
It is provided with and the radially slotted elastic force hole being connected.
This diaphragm spring for clutch will can improve the structural strength of separation finger after the tip flexion of separation finger, be easy to point
From, reduce and wear and tear, raising service life；By setting elastic force hole to improve the elastic-restoring force of diaphragm spring, further subtract
The probability damaged less.
In above-mentioned diaphragm spring for clutch, the arc chord angle size of the rib is 120 °~160 °.
In above-mentioned diaphragm spring for clutch, it is respectively provided with the both sides corner of the rib bottom surface along separation finger
The slot to make way that length direction is set.Slot to make way can reduce friction, it is to avoid separation, while the knot of rib can also be improved further
Structure intensity.
In above-mentioned diaphragm spring for clutch, the length of the slot to make way and the radii ratio of round hole are 1:1
~3:2.Above-mentioned ratio both can guarantee that the structural strength of separation finger, be easy to the separation of separation finger again.
In above-mentioned diaphragm spring for clutch, the elastic force hole is taper type fillet hole.
In above-mentioned diaphragm spring for clutch, two stringcourses in the elastic force hole are respectively positioned on the radial direction of dish-shaped body
On.
In above-mentioned diaphragm spring for clutch, the wall in the elastic force hole is made as the arc towards elastic force hole central protuberance
Face, and the surface of the wall in elastic force hole and dish-shaped body seamlessly transits.Cambered surface is designed to preferably avoid dish-shaped body wear,
Improve service life.
Compared with prior art, the utility model has the following advantages that：
1st, this diaphragm spring for clutch is set on the top of separation finger after the curved rib of bending, it is possible to increase point
From the structural strength of finger, it is easy to separation, reduces abrasion, improves service life；
2nd, this diaphragm spring for clutch is by setting elastic force hole to improve the elastic-restoring force of diaphragm spring, further
Reduce the probability damaged.
