Abstract
The invention discloses a separated finger buffering diaphragm spring of a shock absorber. The separated finger buffering diaphragm spring of the shock absorber comprises a diaphragm spring body and a plurality of separated fingers. The spring body is in a circular ring shape. The separated fingers are distributed on the inner circle of the spring body, and each separated finger is provided with a plurality of wave crests and wave troughs in the radial direction to form a wave-shaped buffering part, wherein the wave crests and the wave troughs are connected in sequence, or each separated finger is provided with a plurality of wave crests and wave troughs in the circumferential direction to form a wave-shaped buffering part, wherein the wave crests and the wave troughs are connected in sequence. The separated fingers are provided with the wave-shaped buffering parts in the radial direction or the circumferential direction, when components make contact, elastic deformation can be generated, rigid abrasion between the components is reduced, and service life is prolonged.
Description
Technical field
The present invention relates to Clutch Technology field, relate 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 motor and gearbox temporary transient separated and engage gradually the power of inputting to speed changer to cut off or to transmit motor.
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.
Yet common spring diaphragm intensity is not high, if increase thickness, lack flexibility, cause rigidity wearing and tearing between parts, working life is shorter.
Summary of the invention
The problem existing for prior art, the invention reside in and 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 separation finger buffer film flat spring, comprising: diaphragm spring main body and a plurality of separation finger; Spring main body is ring; A plurality of separation fingers are distributed on the interior ring of diaphragm spring main body; Each separation finger radially has a plurality of crests that connect successively and trough forms waveform buffer part, or each separation finger forms waveform buffer part along circumferentially having a plurality of 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, a plurality of separation fingers are evenly distributed on the interior ring of diaphragm spring main body.
Preferably, the length of a plurality of separation fingers is identical.
Preferably, separation finger is 4,8 or 16.
In the present invention, separation finger radially or circumferentially has waveform buffer part, when parts contact, can produce elastic strain, has reduced rigidity wearing and tearing between parts, has extended working life.
