Abstract
The utility model discloses a diaphragm spring for an automobile clutch. The utility model provides the diaphragm spring for the automobile clutch, the service life of which can reach more than 3 million times, comprises a disc spring part and a plurality of separated fingers which are uniformly distributed, and is characterized in that the edges of the separated fingers are round edges. The utility model has the beneficial effects that: in normal operation, the diaphragm spring can effectively reduce the bending stress of the diaphragm spring, and makes the service life of the diaphragm spring to be greatly prolonged and reach more than 3 million times.
Description
Technical field
The utility model relates to a kind of automobile clutch diaphragm spring.
Background technique
At present, automobile has just reached its lifetime limitation working life about 1,000,000 times usually with clutch diaphragm spring, thereby causes clutch to lose efficacy.This automobile is not optimized the structure of diaphragm spring in working process completely with diaphragm spring, cause flexural stress size that diaphragm spring produces at work always near the yield point of its material itself, if things go on like this life-span of clutch diaphragm spring has also just shortened greatly.
Summary of the invention
For solving above technical deficiency, the utility model provides the automobile clutch diaphragm spring that can reach a kind of working life more than 3,000,000 times.
The utility model is realized by following measure:
Automobile clutch diaphragm spring of the present utility model comprises that dish spring part refers to that with some uniform separating it is characterized in that: the arris that described separation refers to is the fillet arris.
Automobile clutch diaphragm spring of the present utility model, the fillet radius at described its place, waist hole is 3～15mm, other fillet radius is 0.5～3mm.
Automobile clutch diaphragm spring of the present utility model, the number that described separation refers to are 18～28.
The beneficial effects of the utility model are: in proper functioning, can effectively reduce the diaphragm spring flexural stress, increased the working life of diaphragm spring greatly, can reach 3,000,000 times.
Description of drawings
Fig. 1 is a main TV structure schematic representation of the present utility model.
Fig. 2 is a cross-sectional view of the present utility model.
Among the figure: 1 separation refers to, 2 punching press fillets, 3 seamed edges extruding fillet.
Embodiment
[0012] as shown in Figure 1, 2, diaphragm spring is when design, and especially dish spring part takes not have the acute angle design principle, all limit, the ribs of dish spring part of diaphragm spring all are treated to fillet, and the big I of its fillet decides according to the size of suffered stress in its present position and the work.Separate the arris that refers to and also be treated to fillet, fillet is divided into seamed edge extruding fillet 3 and punching press fillet 2, and generally speaking, seamed edge extruding fillet 3 radiuses are 0.5～3mm, and the punching press fillet 2 at place, diaphragm spring waist hole is greater, is 3～15mm; Diaphragm spring separates and refers to that 1 quantity can suitably increase and separate the quantity that refers to according to the thickness and the Outside diameter adjustment of diaphragm, and about 18-28 separation refers to.
Claims (3)
1. an automobile clutch diaphragm spring comprises that dish spring part refers to (1) with some uniform separating, and it is characterized in that: described separation refers to that the arris of (1) is a fillet, and described fillet comprises seamed edge extruding fillet (3) and punching press fillet (2).
2. automobile clutch diaphragm spring according to claim 1 is characterized in that: its seamed edge extruding fillet (3) radius is 0.5～3mm, and punching press fillet (2) radius is 3～15mm.
