Abstract
The utility model discloses an improved structure of a diaphragm spring used for a DS430 series diaphragm spring clutch, which comprises a spring body with a through hole in the center, wherein twenty identical open slots are evenly formed on the spring body in a circle to form twenty separating fingers, a separating finger window is formed at the outer end of each open slot, and all the separating finger windows at the outer ends of all the open slots have identical size. The utility model can effectively improve the strength of the separating fingers, does not affect or change the original overall design of the automobile clutch operating system and can overcome the problems existing in the diaphragm spring used for the DS430 series diaphragm spring clutch that the separating fingers are thin and long and large in deflection to affect the strength of the separating fingers, causing large deformation, long idle travel and incomplete separation.
Description
Technical field
The utility model relates to a kind of diaphragm spring, is specifically related to the diaphragm spring that uses on the DS430 series diaphragm spring clutch.
Background technique
Spring is the part of the most critical on the automobile diaphragm clutch, plays platen is produced impacting force and cuts off effects such as power, overload protection; 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 directly influences the size of deflection deformation, thereby the length of the backlash that influence separates.As Fig. 1, the DS430 diaphragm spring all adopts 24 teeth (groove) design in the industry at present, because it is little to separate diameter, finger tip is carefully grown, and this design has had a strong impact on to separate and referred to 2 intensity, and distortion is big, backlash is long, separate not thorough, window size on the dish spring part 1 is arranged at interval in addition, and as the big window 3 and the wicket 4 that show among the figure, it also impacts the intensity that separation refers to.
The model utility content
The utility model the technical problem that will just solve just provide a kind of DS430 series diaphragm spring clutch improved structure of diaphragm spring, can effectively improve to separate and refer to that intensity does not influence again and changes the original global design of automobile clutch control system, overcome existing DS430 series diaphragm spring clutch with diaphragm spring since separate refer to carefully grow, deflection deformation is big has influenced the intensity that separation refers to, make that its distortion is big, backlash is long, separates halfway problem.
In order to solve the problems of the technologies described above, the utility model adopts following technological scheme: DS430 series diaphragm spring clutch improved structure of diaphragm spring, comprise that the center is provided with the spring body of through hole, it is characterized in that: uniform ring is provided with 20 identical flutings and forms 20 teeth and separate and to refer to that each fluting outer end is provided with to separate and refers to window on the described body.
Improved, the separation of described each fluting outer end refers to that the window size size is identical.
The utility model can effectively improve to separate and refers to that intensity does not influence again and changes the original global design of automobile clutch control system, overcome existing DS430 series diaphragm spring clutch with diaphragm spring since separate refer to carefully grow, deflection deformation is big has influenced the intensity that separation refers to, make that its distortion is big, backlash is long, separates halfway problem.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is existing DS430 series diaphragm spring clutch diaphragm spring structural representation;
Fig. 2 is the utility model DS430 series diaphragm spring clutch improved structure of diaphragm spring structural representation.
Embodiment
As shown in Figure 2, the utility model DS430 series diaphragm spring clutch improved structure of diaphragm spring, comprise that the center is provided with the spring body 5 of through hole 51, uniform ring is provided with 20 identical flutings 52 and forms 20 separation and refer to 53 on the described body 5, each fluting outer end is provided with to separate and refers to window 54, and the separation of described each fluting outer end refers to that the window size size is identical.Separate and refer to that window 54 is located on the dish spring part 1 of spring body 5.
Claims (2)
1.DS430 serial diaphragm spring clutch improved structure of diaphragm spring, comprise that the center is provided with the spring body of through hole, it is characterized in that: uniform ring is provided with 20 identical flutings and forms 20 teeth and separate and to refer to that each fluting outer end is provided with to separate and refers to window on the described body.
2. DS430 series diaphragm spring clutch improved structure of diaphragm spring according to claim 1, it is characterized in that: the separation of described each fluting outer end refers to that the window size size is identical.
