Abstract
The utility model discloses a separating finger buffering membrane spring of a shock absorber. The separating finger buffering membrane spring comprises a membrane spring body and a plurality of separating fingers, wherein the spring body is annular, the separating fingers are distributed on an inner ring of the membrane spring body, and each separating finger is provided with a plurality of wave crests and wave troughs connected in sequence in the radial direction to form a wavy buffering part, or each separating finger is provided with a plurality of wave crests and wave troughs connected in sequence in the circumferential direction to form a wavy buffering part. According to the separating finger buffering membrane spring of the shock absorber, due to the fact that each separating finger is provided with the wavy buffering part in the radial direction or the circumferential direction, elastic deformation can be generated when parts make contact, rigid abrasion between parts is reduced, and the service life is prolonged.
Description
Technical field
The utility model relates to Clutch Technology field, relates in particular to a kind of vibration damper separation finger buffer film flat spring.
Background technique
In the flywheel casing of automobile clutch between motor and gearbox, with screw, clutch assembly is fixed on the back plane of flywheel, the output shaft of clutch is exactly the input shaft of gearbox.In vehicle traveling process, driver can step on or release the clutch pedal as required, makes that motor and gearbox are temporary transient to be separated and engage gradually, to cut off or to transmit the power of motor to speed changer input.
Diaphragm spring clutch is to have replaced general helical spring and release lever mechanism and the clutch made with diaphragm spring, because it is arranged in central authorities, so also cetnral spring clutch at last.Diaphragm spring be a thin Steel Spring Plate of use make with certain taper, core has the cone shaped spring sheet of many uniform radial grooves.
But common spring diaphragm intensity is not high, if increase thickness, lack flexibility, cause rigidity wearing and tearing between parts, working life is shorter.
Model utility content
The problem existing for prior art, the utility model is to propose a kind of vibration damper separation finger buffer film flat spring, and separation finger is carried out to Cushioning Design, reduces rigidity wearing and tearing between parts, increases the service life.
A kind of vibration damper separation finger buffer film flat spring, comprising: diaphragm spring main body and multiple separation finger; Spring main body is ring; Multiple separation fingers are distributed on the interior ring of diaphragm spring main body; Each separation finger radially has multiple crests that connect successively and trough forms waveform buffer part, or each separation finger forms waveform buffer part along circumferentially having multiple crests that connect successively and trough.
Preferably, each separation finger along the circumferential direction has the crest and two troughs that connect successively and forms waveform buffer part, or each separation finger along the circumferential direction has two crests and the trough that connect successively and forms waveform buffer part.
Preferably, multiple separation fingers are evenly distributed on the interior ring of diaphragm spring main body.
Preferably, the length of multiple separation fingers is identical.
Preferably, separation finger is 4,8 or 16.
In the utility model, separation finger radially or circumferentially has waveform buffer part, in the time that parts contact, can produce elastic strain, has reduced rigidity wearing and tearing between parts, has extended working life.

Embodiment
As shown in Figures 1 to 4, Fig. 1 and Fig. 2 are a kind of vibration damper separation finger buffer film flat spring plan view and side views in the utility model embodiment 1, and Fig. 3 and Fig. 4 are a kind of vibration damper separation finger buffer film flat spring plan view and side views in the utility model embodiment 2.
Referring to figs. 1 through Fig. 4, the utility model embodiment provides a kind of vibration damper separation finger buffer film flat spring, comprising: diaphragm spring main body 1 and multiple separation finger 2; Spring main body 1 is ring, and multiple separation fingers 2 are distributed on the interior ring of diaphragm spring main body 1, for example 4,8 or more.
See figures.1.and.2, in the utility model embodiment 1, each separation finger 2 radially has multiple crest 21 and troughs 22 that connect successively and forms waveform buffer part.
With reference to Fig. 3 and Fig. 4, each separation finger 2 forms waveform buffer part along circumferentially having multiple crest 21 and troughs 22 that connect successively.Particularly, two crests 21 and a trough 22 form waveform buffer part, or two troughs 22 and a crest 21 form waveform buffer part.
In further embodiment, multiple separation fingers 2 are evenly distributed on the interior ring of diaphragm spring main body 1, and the length of multiple separation fingers 2 is identical.
In the utility model, separation finger radially has waveform buffer part, in the time that parts contact, can produce elastic strain, has reduced rigidity wearing and tearing between parts, has extended working life.
The utility model is embodiment provide the above; it is only preferably embodiment of the utility model; but protection domain of the present utility model is not limited to this; any be familiar with those skilled in the art the utility model disclose technical scope in; be equal to replacement or changed according to the technical solution of the utility model and model utility design thereof, within all should being encompassed in protection domain of the present utility model.
