Description
Technical field
The present invention relates to a kind of damper, in particular to a kind of generator damper.
Background technique
Damper, be for inhibit after spring shock-absorbing rebound when concussion and from the impact on road surface.Automobile is widely used in,
For accelerate vehicle frame and body vibrations decaying, to improve ride of vehicle.When by uneven road surface, although shock-absorbing bullet
Spring can filter the vibration on road surface, but spring itself also has reciprocating motion, and damper is exactly for inhibiting this spring to jump
Jump.Damper is too soft, vehicle body will vertical bounce, damper can bring about very much too big resistance firmly, interferes the normal work of spring
Make.In the retrofit process about suspension, hard damper will mutually arrange in pairs or groups with hard spring, and the hardness of spring and vehicle
Weight is closely bound up, therefore heavier vehicle generally uses harder damper.With draw the device that connects of shake crankshaft, for the crankshaft that contends with
Torsional shaking (i.e. the impact force of crankshaft subject cylinder igniting and the phenomenon that twist).And diesel-driven generator at work usually can companion
With high vibration, so needing the mounting shock absorber device under diesel-driven generator.But most of generator currently on the market
Damper functionality is all relatively simple, and damper used in existing diesel-driven generator mostly uses greatly spring structure, although shock-absorbing
The energy of vibration can be absorbed in spring, but spring itself also has reciprocating motion, and is used for a long time, and spring gradually loses
It loses, and traditional generator damper is also all using single spring, damping effect is not very good.For this purpose, we mention
A kind of generator damper out.
Summary of the invention
The main purpose of the present invention is to provide a kind of generator damper, the present invention by install be telescopically connected to bar and
Electromagnetic coil, electromagnetic coil is compression contraction state in upper bush and lower sleeve, when generator is worked, as shaken

Contracting, electromagnetic coil effect buffer damper pressure, the upper bush of advancing side, lower sleeve and are telescopically connected to bar and stretch
Exhibition, electromagnetic coil will be released by pressured state, and electromagnetic coil will generate certain impulse force, and then reach the damping to generator,
Due to being telescopically connected to bar and co-axial line tube-in-tube structure, the more efficient vertical movement for guaranteeing electromagnetic coil improves this and subtracts
Device stability is shaken, to be allowed to more safe and reliable, by the pressure sensor of installation, when being telescopically connected to bar and being under pressure,
It can be acted on pressure sensor by No. two chassis, pressure sensor detects the instantaneous pressure generated when Generator Vibration, electricity
Current strength in magnetic coil is directly controlled by controller, and controller detects pressure according to pressure sensor, while controlling electricity
Magnetic coil size of current changes elastic force direction, size real-time, quickly, to realize damping effect, avoids the occurrence of electromagnetic coil change
The case where shape, ensure that permanent use, by the damping spring of installation, when upper bush, which is under pressure, to be moved down, also can
It acts on damping spring, so as to more improve the damping performance of damper, structure is simple, functional, is suitble to large quantities of
Amount produces and uses, and can effectively solve the problems in background technique.
To achieve the above object, the technical scheme adopted by the invention is as follows:
