In a kind of embodiment, vibration isolator comprises base 1; The bilateral symmetry position of said base 1 is provided with mounting hole, and base 1 is installed on the vehicle frame.
The middle part of said base 1 has annular side plate 11, and annular side plate 11 inwalls are fixedly connected with connecting plate 12, and connecting plate 12 is divided into two cavitys up and down with annular side plate 11.Be provided with down elastomer block 2 in the following cavity 14, be provided with elastomer block 4 in the last cavity 13.Here need to prove that the said noun of locality is upper and lower to be that diagrammatic sketch with vibration isolator shown in Fig. 4 is the benchmark definition; The use that should be appreciated that the said noun of locality should not limit the protection domain that the application asks.Hereinafter described upper and lower orientation speech repeats no more all as benchmark.
The said elastomer block 4 that goes up can be block rubber with said elastomer block 2 down.
The said elastomer block 4 that goes up is provided with cavity with the said inside of elastomer block 2 down; The rigidity of elastomer block is relevant with itself attribute and internal structure, at the set inside cavity of elastomer block, can change the build-in attribute of elastomer block; When the elastomer block compressive deformation, the inner cavity of elastomer block also can compressive deformation, thereby changes the rigidity and the damping of elastomer block, and then plays the vibration isolation effect.Here need to prove, elastomer block set inside cavity, when the pressure elasticity piece, the stiffness variation of elastomer block is mainly relevant with the inner cavity volume variable quantity of elastomer block, and promptly the volume-variation amount of elastomer block internal cavities is big more, and the stiffness variation of elastomer block is big more.
When specifically being provided with; Can select rigidity is identical or rigidity is different last elastomer block 4 and following elastomer block 2 according to actual needs for use; When last elastomer block 4 and following elastomer block 2 set inside cavitys; The shape of elastomer block internal cavities can be set according to actual needs, and the cavity of two elastomer block is set to identical shaped or difformity, so that elastomer block has same degree or stiffness variation in various degree as required when pressurized.
Internal cavities that can elastomer block is set to ellipse; When oval-shaped major axis is in substantially horizontal; It is bigger that elastomer block is isolated contribution to the vibration of vertical direction, and when oval-shaped major axis was in vertical direction, it is bigger that elastomer block is isolated contribution to the vibration of substantially horizontal.
Said top of going up elastomer block 4 also is provided with cover plate 5, the annular side plate 11 that said cover plate 5 also has annular side plate and surrounds base 1, as shown in Figure 5; Elastomer block 4 and following elastomer block 2 on like this can seal protection be avoided elastomer block 4 and following elastomer block 2 to receive the corrosion of oil gas etc. and are worn out, and have prolonged the working life of vibration isolator.
Further, in order to guarantee the sealing between cover plate 5 and the base 1, can between cover plate 5 and base 1, seal ring 3 be set.Said seal ring 3 can be the wool felt seal ring.
Said cover plate 5, go up the connecting plate 12 of elastomer block 4, base 1 and down the middle part of elastomer block 2 be provided with through hole, by coupling shaft 7 assemblings.Coupling shaft 7 passes down the through hole of the connecting plate 12 of elastomer block 2, base 1, last elastomer block 4 and cover plate 5 successively, and is fastening by pre-load nut 6.
The upper end of coupling shaft 7 is provided with the screw thread that matches with pre-load nut 6.The lower end of coupling shaft 7 is provided with first boss that matches with 1 time cavity 14 of base, and the annular table terrace 71 of coupling shaft 7 first boss contacts and support elastomer block 2 down with the bottom surface of following elastomer block 2.
Thereby constantly press down upward elastomer block 4 of cover plate 5 compressions through tightening pre-load nut 6, and then compress the cavity of going up elastomer block 4 inside, can increase the rigidity that goes up elastomer block 4; Thereby simultaneously through on draw upwards compression elastomer block 2 down of coupling shaft 7, and then the compression inner cavity of elastomer block 4 down can increase the rigidity of elastomer block 2 down.
So same vibration isolator only need be regulated the fastening nut screw-down torque, can change self rigidity, satisfy the vibration isolation needs of different motors or power assembly.
When using this vibration isolator, base 1 is installed on the vehicle frame, the upper end of vibration isolator through coupling shaft 7 and cover plate 5 on stationary engine or other support devices; Can be supporting base and coupling shaft 7 is fixing through nut, supporting base is provided with mounting hole and can be connected with motor or other support devices.
When motor or power assembly upwards vibrate; Because motor or power assembly are connected with the upper end of coupling shaft 7; So thereby motor or power assembly drive the coupling shaft 7 compression elastomer block 2 down that moves upward, so compression down elastomer block 2 internal cavities and increase the rigidity of elastomer block 2 down.When motor or power assembly vibrate, press down cover plate 5 through motor or power assembly, thereby elastomer block 4 is gone up in compression, and then compression is gone up the internal cavities of elastomer block 4 and is increased the rigidity that goes up elastomer block 4 downwards.Thereby this vibration isolator can play the effect of vibration isolation simultaneously up and down.
In the automobile actual motion; The amplitude of motor or power assembly up-down vibration maybe be inconsistent; So when being provided with can through choose different-stiffness on elastomer block 4 and following elastomer block 2; Also can be through regulating the rigidity of elastomer block at the cavity of the set inside difformity of last elastomer block 4 and following elastomer block or number, the mode that can certainly adopt both to combine makes and goes up elastomer block 4 and following elastomer block 2 can be regulated rigidity separately according to actual needs.
When motor or power assembly low-frequency vibration, require vibration isolator rigidity and damping all very big, can play good position-limiting action; During dither, require that vibration isolator rigidity and damping are less plays the vibration isolation effect.
In general; During low-frequency vibration, amplitude shift is bigger, and the decrement of elastomer block 4 or following elastomer block 2 is bigger on this moment; Thereby make and go up elastomer block 4 or the rigidity increase of elastomer block 2 down; Function with control power assembly relative movement and displacement, can overcome with balance because of reaction force and inertial force that high pulling torque output or emergency braking produce, power assembly is played good supporting and position-limiting action.During dither, amplitude shift is less, and is less to the decrement of last elastomer block 4 or following elastomer block 2; Thereby make the rigidity that goes up elastomer block 4 or following elastomer block 2 reduce; And then the vibration that can isolate power assembly effectively reduces the vibration noise in the compartment to the vehicle frame transmission, the raising travelling comfort.
Can further improve vibration isolator mentioned above.
May be in practical application overweight or vibrate excessive situation because of institute's supporting object, like the motor variable working condition or when jolting road traveling, make that upper cover plate 5 pressurizeds are excessive and contact base 1 causes vibration to be directly passed to base 1 and then to pass to vehicle frame; Spring 8 can further be set in above-mentioned vibration isolator, with hinder vibration when excessive upper cover plate 5 contact with base 1.

Here need to prove; The setting of coupling shaft 7 second boss will guarantee that the annular table terrace 72 of second boss can not be lower than the upper surface of base 1 connecting plate 12; Otherwise spring 8 can contact connecting plates 12, vibrate can cause engine luggine to pass to vehicle frame through upper cover plate 5-spring 8-connecting plate 12-base 1 when excessive.
During large amplitude; The elastomer block and the internal cavities thereof of vibration isolator are compressed distortion, make rigidity, damping become big, when amplitude is excessive cause spring 8 to work after; Can strengthen the rigidity and the damping of vibration isolator further; Because of engine output torque changes the violent oscillatory motion that causes, more help preventing impacting in vehicle starting, braking, gearshift and acceleration and the moderating process of more effectively decaying, suppress the displacement amplitude of power assembly.
Above-mentioned vibration isolator mainly plays promptly the decay transfer of vibration of vertical direction of up and down vibration isolation effect, but in actual motion, motor or other vibration of device on vertical direction, also has the vibration on other direction such as torsional moment such as the substantially horizontal.
In order to enlarge the Applicable scope of vibration isolator, can do improvement further to above-mentioned vibration isolator.
In the third embodiment; The upper end of the last elastomer block 4 of said vibration isolator is respectively arranged with taper concave station structure with the lower end of following elastomer block 2; Correspondingly; Said cover plate 5 be provided with last elastomer block 4 on the boss structure that is complementary of end toper concave station, the bottom of said coupling shaft 7 is provided with the boss structure that is complementary with 2 times end toper concave stations of following elastomer block structure.
After so being provided with, this vibration isolator not only can play the effect of vibration isolation decay vertical direction transfer of vibration up and down, the transfer of vibration on other directions such as having torsional moment that can also decay such as the substantially horizontal.
Further; Can be obliquely installed with following elastomer block 2 inner oblong cavity going up elastomer block 4; Major axis or the minor axis and the substantially horizontal that are oblong cavity are certain angle, to change the rigidity of elastomer block at different direction, specifically are provided with and can regulate as required.
