Abstract
The invention discloses a diaphragm spring for a clutch. The whole diaphragm spring is of a disc-shaped structure and comprises a disc spring and a plurality of separated fingers. The separated fingers are centrally symmetric by using the disc spring as the center of the circle. The inner circle of the disc spring and the separated fingers are connected into a whole. Stress holes are formed in the portion, connected with the separated fingers, of the disc spring. The separated fingers are stamped to be stair-shaped separated fingers to be bent. The separated fingers are divided into three sets. Each set of separated fingers is provided with short separated fingers to form separated fingers with unequal lengths. The outer circle of the disc spring is in finish machining and is precisely matched and positioned with the interior of a clutch cover. When the diaphragm spring normally works, the diaphragm spring can be accurately positioned, pulling rings are separated, deflection during working is avoided, the separated fingers are stamped and bent to be in different sizes as needed, and therefore the aim that the clutch assembly separated fingers are highly consistent is achieved.
Description
Technical field
The present invention relates to a kind of Automobile Clutch Plate Spring, belong to field of automobile.
Background technique
At present, along with truck coupling Engine torque is increasing, vapour vehicle clutch impacting force is also increasing, more and more stricter to clutch performance requirement, not only require assembly itself will have outside enough strength and stiffness, also require higher assembly precision: diaphragm spring positioning precision, separated draw ring positioning precision etc.
Market upper diaphragm spring clutch generally adopts rivet to be fixed on clutch housing, or be sleeved in clutch housing inner chamber, in clutch working procedure, due to the effect of centrifugal force and impacting force, can there is certain skew in diaphragm spring, thereby affect the stability of assembly.Separated draw ring is to locate by the separation finger of diaphragm spring, so the structure of separation finger and positioning precision affect the centering location of separated draw ring to a great extent, thereby affects separated draw ring working life.
So, to accurately diaphragm spring and separated draw ring location just to become to affect one of key issue of large impacting force clutch assembly.
Simultaneously, because load strengthens, platen assembly needs to strengthen, thereby can affect the fitted position of assembly on diaphragm spring separation finger height, make easily because of assembly structure size difference, to cause fitted position different between different products, affect the conformity of Product Assembly.
Summary of the invention
Technical problem to be solved by this invention is.
For solving this technical problem, the invention provides a kind of diaphragm spring for clutch, the integral body of described diaphragm spring is disc-shaped structure, comprise dish spring and a plurality of separation finger, described separation finger is with dish spring center of circle Central Symmetry, inner circle and the separation finger of dish spring are connected as a single entity, in the attachment portion of dish spring and separation finger, be provided with stress hole, the stepped separation finger bending that is stamped out of described separation finger, described a plurality of separation finger is divided into three groups, in every group, be provided with short separation finger and form not isometric separation finger, the cylindrical of described dish spring is fine finishing, accurately coordinate location with the inside of clutch cover.
Described a plurality of separation finger is 24, at interval of 6 separation fingers, is provided with 2 short separation fingers.
Described a plurality of separation finger is 15,18,21, is provided with 1 ~ 2 short separation finger in every group and forms not isometric separation finger.
Fixedly separated draw ring between described not isometric separation finger.
Described dish spring and separation finger are made by silicon-manganese spring steel and the whole punching press of chromium vanadium steel.
Beneficial effect: the present invention is in normal operation, and positioning film spring and separated draw ring, deflection occurs while avoiding work accurately; Separation finger pressing and bending as required bending goes out different size, thereby reach, guarantees the consistent object of clutch assembly separation finger height.

Embodiment
Below in conjunction with drawings and Examples, the present invention is specifically described.
Figure 1 shows that structural representation plan view of the present invention.
Integral body of the present invention is disc-shaped structure, comprises dish spring 1 and a plurality of separation finger 2, and described separation finger 2 is with dish spring 1 center of circle Central Symmetry, and the inner circle of dish spring 1 and separation finger 2 are connected as a single entity, and in dish spring 1 and the attachment portion of separation finger 2, is provided with stress hole 11.
Described a plurality of separation finger 2 is divided into three groups, is provided with short separation finger 13 in every group and forms not isometric separation finger, fixedly separated draw ring 7 between described not isometric separation finger.
Not isometric separation finger is in order to coordinate separated draw ring 7 excircle part, control the separated draw ring 7 rear positions of assembling, by adopting not isometric separation finger structure, better guarantee the matching size between separation finger 2 and separated draw ring 7, do not affecting under the prerequisite of separation finger 2 and separated draw ring 7 intensity, with separation finger 2 medial extremitys, better control separated draw ring 7 rigging positions, guarantee the centering of separated draw ring 7.
The cylindrical of described dish spring 1 is fine finishing, accurately coordinates location with the inside of clutch cover 3, guarantees not to be offset in diaphragm spring 5 assemblings and work.
Figure 2 shows that cross-sectional view of the present invention.
The stepped separation finger bending 12 that is stamped out of described separation finger 2, after controlling assembling, separation finger 2 assemblings highly, can control platen assembly separation finger 2 height that adapt to different loads by controlling punching press shape, a series of platen assembly separation finger 2 assemblings are highly consistent, improve assembling conformity.
Described a plurality of separation finger 2 is 24, at interval of 6 separation fingers 2, is provided with 2 short separation fingers 13.
Described a plurality of separation finger 2 is 15,18,21, is provided with 1 ~ 2 short separation finger 13 in every group and forms not isometric separation finger.
Described dish spring 1 is made by silicon-manganese spring steel or the whole punching press of chromium vanadium steel with separation finger 2.
Figure 3 shows that the present invention assembles decomposing schematic representation.
Figure 4 shows that the present invention assembles schematic diagram.
In same model size situation, the larger clutch assembly of load is for proof strength, component part quality is also just larger, need the problem solving to be, must be in the situation that not taking more spaces, not gaining in weight and add other component, the centering of clutch diaphragm spring, separated draw ring and flywheel rotating shaft while guaranteeing severe duty.Improve the general degree of assembling of product, except guaranteeing the positions such as attachment bolt, also need to ensure unified separation finger height.For this reason, the present invention adopts separation finger to stamp out several bendings, separation finger length difference and the accurately machined technological scheme of diaphragm spring cylindrical, in normal operation, positioning film spring and separated draw ring accurately, while avoiding work, there is deflection, separation finger pressing and bending as required bending goes out different size, thereby reach, guarantees the consistent object of clutch assembly separation finger height.
The above-mentioned embodiment of the present invention, just illustrates, and is not only, and change within the scope of the present invention all or that be equal in scope of the present invention is all surrounded by the present invention.
