Abstract
The invention discloses a kind of separated finger tooth joint diaphragm spring, comprise the spring body, spring body center is the high frequency hard area that is provided with through hole, be that center ring is provided with some long grooves that lead to through hole with the through hole on the spring body, also be provided with a short groove on the spring body between described per two long grooves, short groove is not communicated with through hole, and described short groove position is arranged on beyond the high frequency hard area.The separation that the present invention has effectively improved diaphragm spring refers to intensity, has not only increased area of contact and wear resistance that diaphragm spring separates finger tip and release bearing, makes separation more thorough, is convenient to gear shift, has improved the usability of clutch.
Description
Technical field
The present invention relates to a kind of diaphragm spring, specifically is the separated finger tooth joint diaphragm spring that uses on the automobile diaphragm clutch.
Background technique
Diaphragm spring is the part of the most critical on the automobile diaphragm clutch, plays platen is produced impacting force and lever centrifugation; When clutch shift, driver's let slip the clutch makes shift fork stir release bearing by clutch operating system, and release bearing contacts with the diaphragm spring finger tip, and the diaphragm spring finger tip is depressed, and the big end in dish district has been lifted up and realized separating.Because the intensity of separating finger tip can influence the size of deflection deformation, thereby the length of the backlash that influence separates.Branch groove designs such as diaphragm spring all adopts in the industry at present, finger tip does not have continuous.But it is little to separate diameter at existing main frame auxiliary products, and finger tip is carefully grown, and this design has had a strong impact on and separated the intensity that refers to, distortion is big, backlash is long, separates not thorough.
Summary of the invention
The present invention to be exactly to separate at existing diaphragm spring to refer to that thin and long, that deflection deformation is big problem provides a kind of effective raising to separate and referred to that intensity does not influence and change the separated finger tooth joint diaphragm spring of the original global design of clutch operating system with regard to the technical problem that solves.
In order to solve the problems of the technologies described above, the present invention adopts following technological scheme: separated finger tooth joint diaphragm spring, comprise the spring body, spring body center is the high frequency hard area that is provided with through hole, it is characterized in that: be that center ring is provided with some long grooves that lead to through hole with the through hole on the spring body, also be provided with a short groove on the spring body between described per two long grooves, short groove is not communicated with through hole.
Preferably, described short groove position is arranged on beyond the high frequency hard area.
Preferably, the inner of described short groove is apart from high frequency hard area 6 ~ 7mm.
It is the semi-circle of diameter that described short groove the inner is designed to the groove width.
The present invention adopts technique scheme, the separation that has effectively improved diaphragm spring refers to intensity, area of contact and wear resistance that diaphragm spring separates finger tip and release bearing have not only been increased, and through cap assembly clutch comprehensive performance detection shortening backlash 0.5mm, make separation more thorough, be convenient to gear shift, improved the usability of clutch.
Description of drawings
The invention will be further described below in conjunction with accompanying drawing:
Fig. 1 is the structural representation of separated finger tooth joint diaphragm spring of the present invention.
Embodiment
As shown in Figure 1, be separated finger tooth joint diaphragm spring of the present invention, comprise spring body 1, spring body center is the high frequency hard area 3 that is provided with through hole 2, be that center ring is provided with some long grooves 4 that lead to through hole with through hole 2 on the spring body, also be provided with a short groove 5 on the spring body between described per two long grooves, short groove is not communicated with through hole 2, the short groove that is not communicated with has at interval formed the company's toothing that links to each other in twos, described short groove position is arranged on beyond the high frequency hard area, the inner of short groove is apart from high frequency hard area 6 ~ 7mm, and it is the semi-circle 6 of diameter that short groove the inner is designed to the groove width.
Claims (4)
1, separated finger tooth joint diaphragm spring, comprise the spring body, spring body center is the high frequency hard area that is provided with through hole, it is characterized in that: be that center ring is provided with some long grooves that lead to through hole with the through hole on the spring body, also be provided with a short groove on the spring body between described per two long grooves, short groove is not communicated with through hole.
