Description

  The present invention relates to a liquid-filled vibration-proof mount.

  2. Description of the Related Art Conventionally, two mounting members respectively connected to the support side and the supported side, an elastic body that connects both the mounting members, a diaphragm that forms a liquid chamber between the elastic bodies, and the liquid chamber Is divided into a pressure receiving chamber and an equilibrium chamber, a storage chamber is formed therein, a partition member in which through holes are formed in the upper and lower wall portions of the storage chamber, an orifice passage communicating the pressure receiving chamber and the equilibrium chamber, and storage A liquid-filled vibration-proof mount that includes a movable plate housed in a chamber is known (see, for example, Patent Document 1). The liquid (buffer solution) flows between the pressure receiving chamber and the equilibrium chamber through the orifice passage, so that low frequency and large amplitude vibrations such as engine shake are absorbed and attenuated. By moving at, high-frequency and small-amplitude vibrations such as idle vibrations are absorbed and damped.

In general, liquid-filled vibration-proof mounts are required to have high damping characteristics. This is particularly noticeable when the engine is supported by three engine mounts including one liquid-filled anti-vibration mount. In order to improve the damping characteristics, the shape of the main spring of the elastic body is made to have a high effect of pushing out the liquid in one of the pressure receiving chamber and the equilibrium chamber to the other chamber through the orifice passage, the so-called piston effect. Or the orifice passage is made sufficiently long.

  However, in the configuration as described above, a large pressure difference (abrupt pressure gradient) is generated between the central side (portion corresponding to the piston cross section) and the outer peripheral side due to the piston effect (that is, the central side in the liquid chamber). Or the turbulent flow is likely to occur around the movable plate near the peak of the damping characteristic. For this reason, the input of vibration to the movable plate is increased, and as a result, the durability of the movable plate is lowered, and the movable plate may collide with the upper and lower wall portions of the partition member and may generate noise.

  In addition, the movable plate may bend and vibrate due to the piston effect.

  The present invention has been made in view of such a point, and the object of the present invention is to maintain the durability of the movable plate at a high level and suppress the generation of abnormal noise while maintaining the damping characteristic at a high level. An object of the present invention is to provide a liquid-filled vibration-proof mount. It is another object of the present invention to provide a liquid-filled vibration-proof mount that suppresses the vibration of the movable plate from bending or rotating.

According to a first aspect of the present invention, there are provided two attachment members respectively connected to the support side and the supported side, an elastic body connecting the both attachment members, a diaphragm forming a liquid chamber between the elastic bodies, A liquid chamber is divided into a pressure receiving chamber and an equilibrium chamber, a storage chamber is formed inside, and a partition member in which through holes are formed in the upper and lower wall portions of the storage chamber, and an orifice passage communicating the pressure receiving chamber and the equilibrium chamber And a liquid-filled vibration-proof mount including the movable plate housed in the housing chamber, wherein the upper and lower wall portions of the partition member and the upper and lower surfaces of the movable plate are in contact with each other, and the outer periphery of the movable plate The opening is formed in the side surface of the movable plate, the hole is disposed only in the outer peripheral portion of the movable plate, and a plurality of through holes are provided in the middle portion between the central portion and the outer peripheral portion of the movable plate. Holes are formed side by side in the circumferential direction, and one of the upper and lower wall portions of the partition member Are provided with projections of the same number as the through holes that protrude toward the other wall portion and are inserted into the respective through holes at portions corresponding to the through holes in the intermediate portion of the movable plate. It is characterized by being.

  Thereby, since the upper and lower wall portions of the partition member and the upper and lower surfaces of the movable plate are in contact with each other, the movable plate is prevented from colliding with the upper and lower wall portions of the partition member when vibration is input to the mounting member. Can do. Moreover, since the hole is formed in the outer peripheral part of the movable plate, the rigidity of the outer peripheral part of the movable plate is lowered. Therefore, the outer periphery of the movable plate resonates in response to the input of high-frequency vibration such as idle vibration to the mounting member, and this resonance reduces the dynamic spring constant of the liquid-filled anti-vibration mount, thereby preventing high-frequency vibration such as idle vibration. Can absorb and attenuate. Further, since the projections of the partition members are inserted through through holes formed in the middle portion of the movable plate in the circumferential direction, the durability of the movable plate can be maintained at a high level by this insertion. From the above, it is possible to maintain the durability of the movable plate at a high level while maintaining the damping characteristic at a high level and to suppress the generation of abnormal noise.

  Furthermore, since the projection of the partition member is inserted through a through hole formed in the middle portion of the movable plate in the circumferential direction, the insertion suppresses the movable plate from vibrating in a curved manner or rotating. be able to.

  A second invention is characterized in that, in the first invention, a plurality of holes in the outer peripheral portion of the movable plate are arranged side by side in the circumferential direction.

  Thereby, since the hole of the outer peripheral part of a movable plate is comprised with multiple and arrange | positions along with the circumferential direction, the rigidity of the outer peripheral part of a movable plate becomes low over a perimeter. For this reason, the outer periphery of the movable plate resonates over the entire circumference in response to the input of high-frequency vibration such as idle vibration to the mounting member, and this resonance effectively reduces the dynamic spring constant of the liquid-filled vibration-proof mount. High frequency vibrations such as idle vibrations can be efficiently absorbed and attenuated.

  According to a third invention, in the first or second invention, the hole in the outer peripheral portion of the movable plate opens to the side surface of the movable plate and extends radially inward. .

  According to a fourth invention, in the first or second invention, the hole in the outer peripheral portion of the movable plate is open to the side surface and the upper surface or the lower surface of the movable plate, and is substantially L-shaped in a circumferential sectional view. It is formed in the shape.

  A fifth invention is characterized in that, in any one of the first to fourth inventions, the through holes in the intermediate portion of the movable plate are arranged at equal intervals in the circumferential direction. is there.

  Thereby, since the through-holes in the intermediate part of the movable plate are arranged at equal intervals in the circumferential direction, the durability of the movable plate can be maintained at a high level over the entire circumference.

  According to the present invention, since the upper and lower wall portions of the partition member and the upper and lower surfaces of the movable plate are in contact with each other, the movable plate collides with the upper and lower wall portions of the partition member when inputting vibration to the mounting member. In addition, since the hole is formed in the outer peripheral portion of the movable plate, the rigidity of the outer peripheral portion of the movable plate is lowered, and therefore, the outer peripheral portion of the movable plate has a high frequency such as idle vibration to the mounting member. Resonance occurs in response to vibration input, and this resonance lowers the dynamic spring constant of the liquid-sealed anti-vibration mount, absorbs and dampens high-frequency vibrations such as idle vibrations, and surrounds the intermediate part of the movable plate. Since the projections of the partition members are inserted through the through holes formed side by side, the durability of the movable plate can be maintained at a high level by this insertion. From the above, while maintaining the damping characteristics at a high level The movable plate It is possible to suppress the generation of noise while maintaining durability at a high level. Furthermore, since the projection of the partition member is inserted through a through hole formed in the middle portion of the movable plate in the circumferential direction, the insertion suppresses the movable plate from vibrating in a curved manner or rotating. be able to.

The stopper rubber 21 is formed such that the outer peripheral surface side and the lower surface side of the bulging portion 12a are thicker than the upper surface side, and the case 2 connected to the power plant side is horizontally and upwardly. When these are greatly displaced, these rubbers come into contact with the inner peripheral surface and the bottom of the case 2 to restrict the displacement of the case 2.

  FIG. 1 shows a state in which no load is applied to the mount body 10. In this state, the stopper rubber 21 of the mount body 10 and the bottom of the case 2 are close to each other. In the 1G state in which the mounting device 1 is attached to the vehicle body and the static load of the power plant is applied to the mount body 10, the rubber elastic body 13 is bent and the case 2 is displaced downward, although not shown in the figure. A predetermined interval is formed between the stopper rubber 21 and the stopper rubber 21.

  The upper end portion of the connection fitting 12 is disposed substantially coaxially so as to be positioned below the cylindrical member 11 and at the approximate center of the lower end opening, and a rubber elastic body 13 is disposed on the side surface portion of the upper recess. Is provided. On the other hand, the lower part of the connection fitting 12 is inserted through a hole 2b having a diameter larger than that of the lower part of the connection fitting 12 formed at the bottom of the case 2, and the lower end surface of the connection fitting 12 is on the vehicle body side. It is joined to the upper surface of the connecting member to be coupled by a bolt (not shown).

  The rubber elastic body 13 has a mortar-shaped concave portion formed on the inner peripheral side of the lower portion thereof, and the peripheral surface of the concave portion is attached to the tapered side surface portion of the connecting fitting 12. Further, the rubber elastic body 13 is formed in a substantially truncated cone shape so as to expand radially outward from the entire circumference of the connecting fitting 12 and to extend obliquely upward, and its upper portion is directed upward. It is open.

  A main body portion 11 a of the cylindrical member 11 is embedded in the upper portion of the rubber elastic body 13, while the flange portion 11 b of the cylindrical member 11 has a diameter over the entire circumference of the rubber elastic body 13. It protrudes outward in the direction, and is caulked by a flange portion 2a provided at an opening end portion of the bottomed cylindrical case 1 disposed so as to cover the mount main body portion 10 from below.

  A metal orifice plate 31 (corresponding to a partition member) is disposed on the upper portion of the mount main body 10 so as to cover the opening of the upper portion of the rubber elastic body 13, and so as to cover the upper part thereof. A diaphragm 40 is provided, and the rubber elastic body 13 and the diaphragm 40 constitute a liquid chamber 33 in which a buffer solution is sealed.

  An outer peripheral portion of the diaphragm 40 is formed in a substantially hat shape, and an inner peripheral portion of an annular metal fitting 37 provided with a through hole is connected to a central portion thereof. Specifically, the annular bracket 37 includes a top plate portion 37a in which the through hole is formed, a cylindrical side wall portion 37b that curves downward from the outer peripheral end of the top plate portion 37a, and a side wall portion 37b. It consists of the collar part 37c extended toward a circumferential direction outward from a lower end. And the inner peripheral part of the said top-plate part 37c is embed | buried under the diaphragm 40, and the outer peripheral end part of the said collar part 37c is the flange part 11b of the cylindrical member 11 of the mount main-body part 10 in the flange part 2a of the case 2. It is caulked with.

  Further, in the space formed above the mount main body 10 by the annular metal fitting 37, the orifice plate 31 is sandwiched between the metal fitting 37 and the open end of the rubber elastic body 13 on the outer peripheral side thereof. Accordingly, the liquid chamber 33 is partitioned into a pressure receiving chamber 33a on the rubber elastic body 13 side and an equilibrium chamber 33b on the diaphragm 40 side.

  The two liquid chambers 33a and 33b defined by the orifice plate 31 communicate with each other through an orifice passage 34 formed in a spiral shape on the periphery of the orifice plate 31. The buffer solution in the pressure receiving chamber 33a and the equilibrium chamber 33b flows through the orifice passage 34 so that the low-frequency and large-amplitude vibrations acting on the pressure receiving chamber 33a from the rubber elastic body 13 are attenuated. It has become. At this time, the diaphragm 40 is deformed so as to absorb the volume change of the equilibrium chamber 33b accompanying the flow of the buffer solution.

  Here, as shown in FIG. 1, the diaphragm 40 is covered with a substantially hat-shaped cover member 36 so that the diaphragm 40 is damaged or foreign matter such as water or dust is present on the diaphragm 40. And a space for absorbing deformation of the diaphragm 40 is formed between the diaphragm 40 and the cover member 36 and in the vicinity of the shaft center of the vibration-proof mount device 1. It has become.

  The orifice plate 31 includes a main body portion 31a that forms a spiral orifice passage 34, and a disc-shaped lid portion 31b that is disposed so as to contact the upper surface of the main body portion 31a. A movable plate recess 31c having a circular opening cross section is formed in the central portion on the upper surface side of the main body 31a. The accommodation chamber is formed by closing the movable plate recess 31c with the lid 31b. A plurality of through-holes 31d having a circular opening cross section that penetrates in the thickness direction and communicates with the concave portion 31c for the movable plate and the pressure receiving chamber 33a are formed in the bottom portion (corresponding to the lower wall portion of the partition member) of the concave portion 31c for the movable plate. Has been. A part of these through holes 31d is arranged in a portion corresponding to an outer peripheral portion 35g of the movable plate 35 described later. On the upper surface of the bottom of the concave portion 31c for the movable plate, a portion corresponding to each through hole 35h of the movable plate 35 is projected toward the lid portion 31b (upward), and inserted and fixed to each through hole 35h. Two cylindrical pins 31e (corresponding to protrusions) are disposed. The tip of each pin 31e is crushed. For this reason, the upper end opening of each through-hole 35h is sealed. A portion of the lid portion 31b corresponding to the movable plate recess portion 31c (corresponding to the upper wall portion of the partition member) penetrates in the thickness direction and communicates with the movable plate recess portion 31c and the equilibrium chamber 33b. Is formed. A part of these through holes 31f is arranged in a portion corresponding to the outer peripheral portion 35g of the movable plate 35.

  As shown in FIGS. 1 and 2, a movable plate 35 for absorbing high-frequency and small-amplitude vibration is fitted and accommodated in the movable plate recess 31c in a pre-compressed state, and is prevented from falling off by the lid portion 31b. ing. The movable plate 35 is made of a disc-shaped rubber.

  On the upper surface and the lower surface of the movable plate 35, first to third protrusions 35 a to 35 c that protrude outward in the axial direction over the entire circumference are disposed concentrically. Further, on the upper and lower surfaces of the movable plate 35, a hemispherical shape protruding outward in the axial direction at a radially inner portion from the first protrusion 35a and a portion between the first and second protrusions 35a and 35b. A plurality of projecting portions 35d are arranged at equal intervals in the circumferential direction. Further, on the upper and lower surfaces of the movable plate 35, two cylindrical cylindrical portions 35j protruding outward in the axial direction are arranged at equal intervals in the circumferential direction at a portion between the first and second protrusions 35a and 35b. Each is arranged. The hollow portion of the cylindrical portion 35j constitutes a part of the through hole 35h.

  The movable plate 35 has first and second protrusions 35a and 35b on the upper surface, a protrusion 35d and a cylindrical part 35j in close contact with the lower surface of the lid 31b, and the first and second protrusions 35a and 35b on the lower surface. The protruding portion 35d and the cylindrical portion 35j are in close contact with the upper surface of the bottom of the movable plate recess 31c, and the side surfaces are in close contact with the inner peripheral surface of the movable plate recess 31c. For this reason, it is possible to prevent the movable plate 35 from colliding with the lid portion 31b or the movable plate concave portion 31c at the time of input of vibration to the connection portion integrally formed with the connection fitting 12 or the case 2.

  An intermediate portion 35f (first and first portions) between a central portion 35e (a radially inner portion from the first protrusion 35a) and an outer peripheral portion 35g (a radially outer portion from the second protrusion 35b) of the movable plate 35. Two through-holes 35h having a circular opening cross section that penetrates in the thickness direction are formed at equal intervals in the circumferential direction in a portion between the two protrusions 35a and 35b. And since each pin 31e of the recessed part 31c for movable plates is inserted and attached to each through-hole 35h of the movable plate 35 as mentioned above, durability of the movable plate 35 is maintained at a high level by this insertion attachment. At the same time, the movable plate 35 is restrained from bending and rotating.

  A plurality of holes 35i having a circular opening cross section that is open on the side surface of the movable plate 35 and extends inward in the radial direction are formed in the outer peripheral portion 35g of the movable plate 35 so as to be arranged at equal intervals in the circumferential direction. For this reason, the rigidity of the outer peripheral portion 35g of the movable plate 35 is lowered. When high-frequency vibration such as idle vibration is input to the connection portion integrally formed with the connection fitting 12 or the case 2, the outer peripheral portion 35g of the low-rigidity movable plate 35 resonates according to the input vibration. Due to this resonance, the dynamic spring constant of the vibration-proof mount device 1 is lowered, and high-frequency vibrations such as idle vibrations are absorbed and attenuated.

-Effect-
As described above, according to the present embodiment, the bottom of the lid 31b and the movable plate recess 31c of the orifice plate 31 and the upper and lower surfaces of the movable plate 35 are in contact with each other. 2 can be prevented from colliding with the lid 31b of the orifice plate 31 and the bottom of the movable plate recess 31c at the time of input of the vibration to the connecting portion formed integrally. Moreover, since the hole 35i is formed in the outer peripheral part 35g of the movable plate 35, the rigidity of the outer peripheral part 35g of the movable plate 35 becomes low. Therefore, the outer peripheral portion 35g of the movable plate 35 resonates in response to an input of high-frequency vibration such as idle vibration to the coupling portion 12 or the coupling portion formed integrally with the case 2, and this resonance causes the dynamic spring of the vibration-proof mount device 1 to move. The constant becomes low, and high frequency vibration such as idle vibration can be absorbed and damped. Further, since the pin 31e of the orifice plate 31 is inserted into the through-hole 35h formed in the middle part 35f of the movable plate 35 in the circumferential direction, the durability of the movable plate 35 can be maintained at a high level by this insertion. it can. From the above, it is possible to maintain the durability of the movable plate 35 at a high level while maintaining the attenuation characteristic at a high level and to suppress the generation of abnormal noise.

  Further, since the pin 31e of the orifice board 31 is inserted into the through-hole 35h formed in the middle portion 35f of the movable plate 35 in the circumferential direction, the insertion of the movable plate 35 causes vibration or rotation of the movable plate 35. Can be suppressed.

  In addition, since the plurality of holes 35i of the outer peripheral portion 35g of the movable plate 35 are configured and arranged side by side in the circumferential direction, the rigidity of the outer peripheral portion 35g of the movable plate 35 is reduced over the entire circumference. Therefore, the outer peripheral portion 35g of the movable plate 35 resonates over the entire circumference in response to the input of high-frequency vibration such as idle vibration to the coupling portion 12 or the coupling portion integrally formed with the case 2, and this vibration causes vibration-proof mounting. The dynamic spring constant of the device 1 is efficiently reduced, and high-frequency vibrations such as idle vibrations can be efficiently absorbed and damped.

  Moreover, since the through holes 35h of the intermediate portion 35f of the movable plate 35 are arranged at equal intervals in the circumferential direction, the durability of the movable plate 35 can be maintained at a high level over the entire circumference.

  In the present embodiment, the hole 35i as described above is formed in the outer peripheral portion 35g of the movable plate 35, but the length in the radial direction may be appropriately changed. Here, if the length in the radial direction is made longer, the rigidity of the outer peripheral portion 35g of the movable plate 35 is lowered, and the damping characteristic of the high-frequency vibration is enhanced. On the other hand, if the length in the radial direction is shortened, the rigidity of the outer peripheral portion 35 of the movable plate 35 is increased, and the damping characteristic of the low frequency vibration is increased.

(Embodiment 2)
In the present embodiment, the configuration of each hole 35 i in the outer peripheral portion 35 g of the movable plate 35 is different from that in the first embodiment. That is, as shown in FIG. 3, each hole 35 i of the outer peripheral portion 35 g of the movable plate 35 is open on the side surface and the upper surface of the movable plate 35, and is formed in a substantially L shape in a circumferential sectional view. . The opening on the upper surface side of the movable plate 35 of each hole 35i of the outer peripheral portion 35g of the movable plate 35 communicates with the through hole 31f of the lid portion 31b. For this reason, when vibration is input to the connection portion integrally formed with the connection fitting 12 or the case 2, the pressure is input to the hole 35i of the outer peripheral portion 35g of the movable plate 35 through the through hole 31f of the lid portion 31b. The In other respects, the configuration is almost the same as that of the first embodiment.

  Thereby, substantially the same effect as Embodiment 1 is obtained.

  In the present embodiment, each hole 35i of the outer peripheral portion 35g of the movable plate 35 is opened on the side surface and the upper surface of the movable plate 35, but may be opened on the side surface and the lower surface of the movable plate 35.

(Other embodiments)

Further, the protrusions 35a to 35c and the protrusion 35d may not be provided. In this case, the upper surface of the movable plate 35 needs to be in close contact with the lower surface of the lid portion 31b, and the lower surface needs to be in close contact with the upper surface of the bottom portion of the concave portion 31c for the movable plate.

  In the above embodiments, the third protrusions 35c on the upper and lower surfaces of the movable plate 35 are not in close contact with the lower surface of the lid portion 31b and the upper surface of the bottom portion of the movable plate recess 31c. .

  Further, in each of the above embodiments, the hole 35i as described above is formed in the outer peripheral portion 35g of the movable plate 35, but the hole 35i may be any as long as it does not penetrate in the thickness direction.

  Moreover, in each said embodiment, although the some hole 35i is formed in the outer peripheral part 35g of the movable plate 35, this number may be arbitrary values.

  In each of the above embodiments, the two through holes 35h are formed in the intermediate portion 35f of the movable plate 35, and the two pins 31e are disposed at the bottom of the movable plate recess 31c. A through hole 35h may be formed, and the same number of pins 31e may be disposed.

  Further, in each of the above embodiments, the two through holes 35h are formed in the intermediate portion 35f of the movable plate 35 so as to be arranged at equal intervals in the circumferential direction, but may not be formed at equal intervals. However, in order to maintain the durability of the movable plate 35 at a high level over the entire circumference, it is desirable to form the movable plate 35 at equal intervals.

  The present invention is not limited to the embodiments, and can be implemented in various other forms without departing from the spirit or main features thereof.

  As described above, the above-described embodiment is merely an example in all respects and should not be interpreted in a limited manner. The scope of the present invention is indicated by the claims, and is not restricted by the text of the specification.
