Abstract
The utility model discloses a pull type diaphragm spring with an arc groove at the skirt portion, which comprises a pull type diaphragm spring body. The pull type diaphragm spring is characterized in that an arc groove with certain depth and width is arranged at the skirt portion of a separation finger of the pull type diaphragm spring, and the arc groove is in toe contact with a pressing disc. The pull type diaphragm spring can effectively eliminate central derivation in the frequent combination and separation processes between the diaphragm spring and a clutch, thereby prolonging service life of the clutch.
Description
Technical field
The utility model relates to pull-type diaphragm spring, specifically is the pull-type diaphragm spring that a kind of skirt section is provided with arc groove.
Background technique
Usually, automobile adopts the conical structure design with pull-type diaphragm spring, and the skirt section of diaphragm spring refers to be straight line and distributes with separating; In assembling process, because assembly tool and fixing various factors such as sequencing are prone to cause diaphragm spring to produce certain offset; And these offsets cause diaphragm spring after assembling, to produce separation and refer to highly differ; Diaphragm spring separates and to refer to that the automobile that highly differs use pull type clutch, in use, is prone to cause separate refer to inordinate wear, makes clutch reduction in working life.
Summary of the invention
The utility model is for overcoming the deficiency of existing technology, and provides a kind of skirt section to be provided with the pull-type diaphragm spring of arc groove.This pull-type diaphragm spring can effectively be eliminated diaphragm spring and in frequent combination of clutch and separation process, produce off-centring, causes diaphragm spring to separate and refers to highly differ and the inordinate wear problem, thereby improve the working life of clutch.
The technological scheme that realizes the utility model purpose is:
Separate the arc groove that the skirt section that refers to is provided with a certain depth, certain width at pull-type diaphragm spring, arc groove contacts with the platen tooth top.
The degree of depth of described arc groove can be set at 0.5～2mm or darker according to practical application, and width can be set at 3～12mm or wideer according to practical application.
The utility model has the advantages that: through using the diaphragm spring of band arc groove, be that arc groove center on platen tooth top diametrical position and the diaphragm spring skirt section is not overlapping even in assembling process, produce certain offset; Diaphragm spring will be in using process from now on, and offset is eliminated in the effect of the centripetal force that produces through arc groove and platen tooth top automatically, is returned to the use center; Thereby make the actual user mode of diaphragm spring consistent with the design user mode; This pull-type diaphragm spring can effectively be eliminated diaphragm spring and in frequent combination of clutch and separation process, produce off-centring, causes diaphragm spring to separate and refers to highly differ and the inordinate wear problem, thereby improve the working life of clutch.
