In a kind of embodiment, vibration isolator comprises base 1; The bilateral symmetry position of described base 1 is provided with mounting hole, is installed on vehicle frame by base 1.
The middle part of described base 1 has annular side plate 11, and annular side plate 11 inwall is fixedly connected with connecting plate 12, and annular side plate 11 is divided into upper and lower two cavitys by connecting plate 12.Be provided with lower elastomer block 2 in lower cavity 14, in upper cavity 13, be provided with elastomer block 4.Here it should be noted that, the described noun of locality is upper and lower is for benchmark defines with the diagram of vibration isolator shown in Fig. 4; Should be appreciated that the protection domain that the use of the described noun of locality should not limit the application and asks.Hereinafter described the upper and lower noun of locality is all as benchmark, repeats no more.
Described upper elastomer block 4 and described lower elastomer block 2 can be block rubber.
The inside of described upper elastomer block 4 and described lower elastomer block 2 is provided with cavity; The rigidity of elastomer block is relevant with itself attribute and internal structure, arranges cavity, can change the build-in attribute of elastomer block in the inside of elastomer block; When elastomer block compressive deformation, the cavity of elastomer block inside also can compressive deformation, thus changes rigidity and the damping of elastomer block, and then plays vibration isolation effect.Here it should be noted that, elastomer block inside arranges cavity, and when pressure elasticity block, the cavity volume variable quantity of stiffness variation mainly with elastomer block inside of elastomer block is relevant, and namely the volume-variation amount of elastomer block internal cavities is larger, and the stiffness variation of elastomer block is larger.
When specifically arranging, rigidity is identical or rigidity is different upper elastomer block 4 and lower elastomer block 2 can be selected according to actual needs, when upper elastomer block 4 and lower elastomer block 2 inside arrange cavity, the shape of elastomer block internal cavities can be set according to actual needs, the cavity of two elastomer block is set to same shape or difformity, has same degree or stiffness variation in various degree when pressurized as required to make elastomer block.
The internal cavities of elastomer block can be set to ellipse, when the major axis of ellipse is in substantially horizontal, the isolating technique contribution of elastomer block to vertical direction is comparatively large, and when the major axis of ellipse is in vertical direction, the isolating technique contribution of elastomer block to substantially horizontal is larger.
The top of described upper elastomer block 4 is also provided with cover plate 5, and described cover plate 5 also has annular side plate and surrounds the annular side plate 11 of base 1, as shown in Figure 5; Like this can elastomer block 4 and lower elastomer block 2 on seal protection, avoid elastomer block 4 and lower elastomer block 2 to be subject to the corrosion of oil gas etc. and aging, extend the working life of vibration isolator.
Further, in order to ensure the sealing between cover plate 5 and base 1, seal ring 3 can be set between cover plate 5 and base 1.Described seal ring 3 can be wool felt seal ring.
The connecting plate 12 of described cover plate 5, upper elastomer block 4, base 1 and the middle part of lower elastomer block 2 are provided with through hole, are assembled by coupling shaft 7.Coupling shaft 7 is successively through the through hole of lower elastomer block 2, the connecting plate 12 of base 1, upper elastomer block 4 and cover plate 5, fastening by pre-load nut 6.
The upper end of coupling shaft 7 is provided with the screw thread matched with pre-load nut 6.The lower end of coupling shaft 7 is provided with the first boss matched with base 1 time cavity 14, and the annular table terrace 71 of coupling shaft 7 first boss contacts with the bottom surface of lower elastomer block 2 and supports down elastomer block 2.
Cover plate 5 is constantly pressed down thus the upper elastomer block 4 of compression by tightening pre-load nut 6, and then the cavity of upper elastomer block 4 inside of compression, the rigidity of upper elastomer block 4 can be increased; Pass through pull-up coupling shaft 7 simultaneously thus upwards compress lower elastomer block 2, and then the cavity of lower elastomer block 4 inside of compression, the rigidity of lower elastomer block 2 can be increased.
So same vibration isolator only needs to regulate fastening nut screw-down torque, can change stiffness by itself, meet the vibration isolation needs of different motor or power assembly.
When using this vibration isolator, base 1 is installed on vehicle frame, the upper end of vibration isolator by coupling shaft 7 and cover plate 5 on stationary engine or other support devices; Supporting base and coupling shaft 7 can be fixed by nut, supporting base being provided with mounting hole 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 motor or power assembly drive coupling shaft 7 to move upward thus compress elastomer block 2 down, and then compression is descended the internal cavities of elastomer block 2 and increases the rigidity of lower elastomer block 2.When motor or power assembly vibrate, press down cover plate 5 by motor or power assembly downwards, thus the upper elastomer block 4 of compression, and then the internal cavities of the upper elastomer block 4 of compression and increase the rigidity of upper elastomer block 4.Thus, this vibration isolator can play the effect of vibration isolation simultaneously up and down.
In automobile actual motion, the amplitude of motor or power assembly up-down vibration may be inconsistent, so can by choosing the upper elastomer block 4 of different-stiffness and lower elastomer block 2 when arranging, also the rigidity of adjustable elastic block can be carried out by the cavity arranging difformity or number in the inside of upper elastomer block 4 and lower elastomer block, the mode that both combine can certainly be adopted, make elastomer block 4 and lower elastomer block 2 can regulate respective rigidity according to actual needs.
When motor or power assembly low-frequency vibration, require that vibration isolator rigidity and damping are all very large, good position-limiting action can be played; During dither, require vibration isolator rigidity and damping is less plays vibration isolation effect.
In general, during low-frequency vibration, amplitude shift is larger, the decrement now going up elastomer block 4 or lower elastomer block 2 is larger, thus the rigidity of elastomer block 4 or lower elastomer block 2 is increased, there is the function controlling power assembly relative movement and displacement, can overcome and balance the reaction force and inertial force that produce because of high pulling torque output or emergency braking, well supporting and position-limiting action are played to power assembly.During dither, amplitude shift is less, less to the decrement of upper elastomer block 4 or lower elastomer block 2, thus the rigidity of elastomer block 4 or lower elastomer block 2 is reduced, and then the vibration effectively can isolating power assembly is to vehicle frame transmission, reduce the vibration noise in compartment, improve travelling comfort.
Can be further improved vibration isolator mentioned above.
In actual applications may be overweight or vibrate excessive situation because of institute's supporting object, as motor variable working condition or when jolting road traveling, making upper cover plate 5 pressurized excessive and contacting base 1, causing vibration be directly passed to base 1 and then pass to vehicle frame; Can arrange spring 8 further in above-mentioned vibration isolator, during to hinder vibration excessive, upper cover plate 5 contacts with base 1.
In another kind of embodiment, supine second boss of ring-shaped step is provided with in the below of coupling shaft 7, spring 8 is sleeved on coupling shaft 7, the lower end of annular table terrace 72 contact spring 8 of coupling shaft 7 second boss supported spring 8, spring 8, between the annular table terrace 72 and upper elastomer block 4 of cover plate 5, coupling shaft 7 second boss, plays further and regulates rigidity and position-limiting action.Comprehensively the factor such as the weight of actual support thing and the operating conditions of automobile can choose the spring of proper stiffness, cause vibration isolation to be lost efficacy to avoid cover plate 5 to contact with base 1.
Here it should be noted that, the setting of coupling shaft 7 second boss will ensure that the annular table terrace 72 of the second boss can not lower than the upper surface of base 1 connecting plate 12, otherwise spring 8 can contact connecting plate 12, engine luggine when vibrating excessive, can be caused to pass to vehicle frame by upper cover plate 5-spring 8-connecting plate 12-base 1.
During large amplitude, elastomer block and the internal cavities thereof of vibration isolator are compressed distortion, make rigidity, damping change greatly, when amplitude is excessive cause spring 8 to work after, rigidity and the damping of vibration isolator can be strengthened further, because engine output torque changes the violent oscillatory motion caused in vehicle starting, braking, gearshift and acceleration and the moderating process of more effectively decaying, be more conducive to preventing from impacting, suppress the displacement amplitude of power assembly.
Above-mentioned vibration isolator mainly plays upper and lower vibration isolation effect and namely to decay the vibration passing of vertical direction, but in actual motion, motor or other devices, except the vibration on vertical direction, also exist other directions such as torsional moment as the vibration in substantially horizontal.
In order to expand the Applicable scope of vibration isolator, can do above-mentioned vibration isolator and further improving.
In the third embodiment, the upper end of the upper elastomer block 4 of described vibration isolator and the lower end of lower elastomer block 2 are respectively arranged with taper concave station structure, correspondingly, described cover plate 5 is provided with the boss structure matched with end toper concave station in upper elastomer block 4, the bottom of described coupling shaft 7 is provided with the boss structure matched with lower elastomer block 2 times end toper concave station structures.
After so arranging, this vibration isolator not only can play the effect of upper and lower vibration isolation decay vertical direction vibration passing, and other directions such as there is torsional moment of can also decaying are as the vibration passing in substantially horizontal.
Further, the oblong cavity of upper elastomer block 4 and lower elastomer block 2 inside can be obliquely installed, namely the major axis of oblong cavity or minor axis and substantially horizontal at an angle, to change the rigidity of elastomer block at different direction, specifically arrange and can regulate as required.
Compared with prior art, vibration isolator provided by the invention arranges cavity structure and arranges large rigidity spring in elastomer block, in actual motion, vibration isolator can regulate rigidity and the damping of vibration isolator automatically according to the difference of decrement, adapts to the different operating modes of automobilism.In addition, the structure of this vibration isolator is simple, easy accessibility, and each component have enough intensity and reliability; Each component can generalization, standardization and seriation.
In addition, the Static stiffness of this vibration isolator is comparatively large, can play position-limiting action effectively, and can ensure that vibration isolator amplitude load change is mild to power assembly; This vibration isolator presses down upper elastomer block by the fastening cover plate of pre-load nut and coupling shaft pull-up compresses lower elastomer block, can play the effect of vibration isolation simultaneously up and down.
