[0002] Diaphragm spring is a conical spring leaf with many radial grooves in the center. It is a key part of the automobile diaphragm clutch. The clutch is driven and separated by pulling or pushing the diaphragm spring through the release bearing; however, The strength of the ordinary spring diaphragm is not high, and the finger end of the release finger of the diaphragm spring is directly in contact with the release bearing, which often leads to abnormal wear or even breakage of the finger end, which directly affects the performance and service life of the clutch.

Embodiment Construction
[0019] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.
[0020] Such as figure 1 and figure 2 As shown, a diaphragm spring includes a spring body 1, the spring body 1 is provided with a plurality of radial slots 11, and a separating finger 12 is formed between two adjacent radial slots 11; The radial slots 11 are evenly distributed on the spring body 1 to ensure that each separation finger 12 bears a balanced force and is not prone to breakage.
[0021] Such as figure 1 and figure 2 As shown, the diaphragm spring also includes two protective seats 2 symmetrically arranged on both sides of the spring body 1, and the protective seats 2 include end caps 21 and connectors 22 corresponding to the separating fingers 12 one by one. , the middle part 122 of the end cover 21...

The invention relates to a diaphragm spring which comprises a spring body. A plurality of radial grooves are formed in the spring body; a separating finger is formed between every two radial grooves; the diaphragm spring further comprises two protective seats symmetrically arranged on the two sides of the spring body; the protective seats comprise end covers and connecting pieces in one-to-one correspondence to the separating fingers; mounting holes are formed in the middles of the end covers; the connecting pieces comprise horizontal plates and vertical plates, the first ends of the vertical plates are fixed on the end covers, and the second ends of the vertical plates are connected with the horizontal plates; a plurality of through holes in one-to-one correspondence to the radial grooves are further formed in the end covers; and the first ends of the vertical plates are fixed in the positions, close to one edges of the through holes, of the end covers. According to the diaphragm spring, the two protective seats are additionally arranged on the left and right sides of the spring body, the problem that the finger ends of the separating fingers are prone to being abraded and fractured can be effectively solved, meanwhile, the structures of the two protective seats are completely identical, the production cost is lower, and assembly is easy and quick.
Description
technical field [0001] The invention relates to a spring, in particular to a diaphragm spring. Background technique [0002] Diaphragm spring is a conical spring leaf with many radial grooves in the center. It is a key part of the automobile diaphragm clutch. The clutch is driven and separated by pulling or pushing the diaphragm spring through the release bearing; however, The strength of the ordinary spring diaphragm is not high, and the finger end of the release finger of the diaphragm spring is directly in contact with the release bearing, which often leads to abnormal wear or even breakage of the finger end, which directly affects the performance and service life of the clutch. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a diaphragm spring to overcome the above-mentioned deficiencies in the prior art. [0004] The technical solution of the present invention to solve the above-mentioned technical problems...
