Specific embodiment
The present invention is described in further details below in conjunction with Figure of description and specific embodiment, but not therefore and
It limits the scope of the invention.
As shown in Figure 1, the track floating plate vibration isolator of the present embodiment, including upper cover plate 1, bottom plate 2, telescopic 3 and every
Shake component 4.Wherein, telescopic 3 is connected to formation sealed chamber 5 between upper cover plate 1 and bottom plate 2, simple and compact for structure.Together
When, the setting of sealed chamber 5 has good anti-corrosion and anti-aging so that vibration isolation component 4 is effectively isolated with outside air and water
Function, so that each component is reusable, maintenance cost is low；And vibration isolator has excellent waterproof sealing effect, in vibration isolation group
Part 4 prevents damping agent 41 from revealing when working, and guarantees the vibration isolating effect and operational reliability of vibration isolator.
Meanwhile vibration isolation component 4 includes damping agent 41, helical form dampened disk 42 and spring 43.Wherein, damping agent 41 is set to close
It seals in chamber 5；One end of helical form dampened disk 42 is removably installed on upper cover plate 1, the other end of helical form dampened disk 42
It protrudes into damping agent 41；Spring 43 is installed between upper cover plate and bottom plate.Its is simple and compact for structure, and helical form dampened disk 42 can
The form of disassembly installation to can be realized under conditions of being changed without other parts by the size and the number of plies that change dampened disk
Adjustable replaceable function is damped, and easy to adjust, quick.Meanwhile the helical form setting form of dampened disk is conducive to damping agent 41
Flowing inside vibration isolator, effectively increase vibration isolator subtracts vibration isolating effect.
For vehicle after evoking floating panel vibration, vibration isolator generates vertical motion therewith, and spring 43 mainly plays support at this time
And the effect of vibration isolation, and spring 43 and helical form dampened disk 42 generate vertical motion simultaneously under the action of upper cover plate 1, and with resistance
Buddhist nun's agent 41 acts on, and then generates damping, plays the role of energy consumption, energy consumption effect is good, reduces the energy of wheel-rail interaction
Transmitting to floating plate basis reduces the influence to ambient enviroment.
In the present embodiment, the number of plies and radius of helical form dampened disk 42 are to guarantee to provide to subtract vibration isolation damping enough as standard choosing
It selects.Helical form dampened disk is improved by the radius of the number of plies or/and helical form dampened disk 42 that increase contorted dampened disk 42
42 with the contact area of damping agent 41, pass through the radius of the number of plies or/and helical form dampened disk 42 that reduce contorted dampened disk 42
Reduce helical form dampened disk 42 and damping agent 41 contact area, thus realize damping it is adjustable, with provide it is enough subtract vibration isolation hinder
Buddhist nun." provide and subtract vibration isolation damping enough " is using the enough resonance inhibited near shared frequency, effectively consumption vibrational energy as standard.This
In embodiment, the vibration isolation damping ratio that subtracts of track floating plate vibration isolator is 5%~8%, in other embodiments, subtracts vibration isolation damping
It is adjusted according to the application of vibration isolator.
Further, helical form dampened disk 42 is to be threadedly coupled with upper cover plate 1, so that helical form dampened disk when adjustment damping
42 replacement is convenient, ensure that effectively fast implementing for vibration isolator damping adjustable function.As shown in Figure 1, stretching in the present embodiment
