Device problem, but its complicated integral structure, installation requirement are high.Application No. CN201611056591.X patent pin both the above simultaneously
Technology proposes a kind of resonance free peak vibration isolator and its damping module, and it is improved mainly for damper, wear-resisting using two
Damper made of elastic rubber material suppresses resonance, decay impact, efficiently solves both the above patent damper structure
Complexity, the problem of installation difficulty；But in actual use, the vibration isolator under low frequency impact incentive action environment, its
Effectiveness in vibration suppression is limited；Under the high temperature conditions, rubber is easily deformed destruction, and vibration isolator is caused to damage simultaneously.
The content of the invention
In view of the above-mentioned problems, the present invention provide it is a kind of it is simple in construction, reduce spring pad wear modified resonance free peak every
Shake device, and it also has the advantages of anti-vibration and shock effect is good, service life is longer.
A kind of modified resonance free peak vibration isolator, including main spring Damping modules, shell fragment damping buffering module, installation connection
Module；Shell fragment damping module includes shell fragment component and main spring set, and main spring covers one end and is installed on inside installation link block, separately

The principle of the present invention：Between the boss for the bottom that damping force needed for suppression resonance is covered by shell fragment component and main spring just
Pressure is produced, and the spring leaf quantity of shell fragment component is selected according to actual bearer amount, and bearing capacity is bigger, the spring of shell fragment component
Piece quantity is more.Upper end cover is screwed in vertical direction, the boss that shell fragment component and main spring cover further is compressed, so as to increase
Normal pressure between upper end cover and shell fragment component, and then increase damping force；Upper end cover is unscrewed, damping force reduces.In the horizontal direction
On, the frictional force between upper end cover, bottom plate and cushion cover determines the size of horizontal damping power, screws upper end cover, so as to increase water
Flat damping force；Upper end cover is unscrewed, so as to reduce horizontal damping power.
When resisting impulsive force, impulsive force caused by impact and impact energy are undertaken by shell fragment component.Shell fragment component and master
The contact of the lower boss of spring housing, the spring leaf protruded laterally produce plastic deformation so as to effectively obtain impact resistance,
It is effectively protected the adverse effect that main spring is not hit.
Advantages of the present invention：Connected using the shell fragment component and main spring set of upper and lower both sides, avoided under main spring set
Directly strong alternation friction between the boss and spring leaf in portion, in resistance impact and resonance, mainly by the deformation of shell fragment component
And the contact with shell fragment component of main spring set undertakes, and is effectively protected the adverse effect that main spring is not hit；And
The symmetrical shell fragment component that upper and lower both sides are set, can play interval damping action, reduce each single bullet in a pair of shell fragment components
The frequency of use of piece component, so as to extend the service life of shell fragment component, and then make it that vibration isolator is more robust；Bullet in the present invention
Piece component forms consistent with specification, possesses good versatility, each shell fragment component and comprising parts energy it is general, therefore
It is simple in construction, interchangeability is good, processing be easier, it is more cost-effective；The shell fragment component of the present invention includes spring leaf, cushion cover and card
Ring, by the way that the end of spring leaf is embedded in cushion cover, then snap ring is entangled on the outside of cushion cover, so as to which spring leaf is clamped in into pad
In set and snap ring so that the installation of shell fragment component is stable, reliable operation, and use is more longlasting；After the spring leaf installation of the present invention, spring
The middle part convex of piece, therefore when resisting impact, caused deformation is bigger, and deformation restorability is more preferable, can preferably resist
Adverse effect caused by impact.
