Description

  INDUSTRIAL APPLICABILITY The present invention is used for an anti-vibration mount for an engine or motor of an automobile, a construction machine, an industrial machine, an anti-vibration mount for a cab of a large automobile or a construction machine, and an anti-vibration mount of an industrial machine generator. The present invention relates to a liquid-filled mount.

  The anti-vibration mount supports the anti-vibration body and insulates vibration from a base such as a vehicle body. 2. Description of the Related Art Conventionally, for example, a technique has been disclosed in which a load of a vibration-proof body is supported by a mount rubber or a built-in coil spring, and vibrations input by the flow resistance of a highly viscous liquid sealed in a container are attenuated.

  In the liquid-sealed mount disclosed in Patent Document 1, the opening of the container is closed by a mount rubber (17) through which a stud (14) penetrates in the center, and the damping plate (15) attached to the lower end of the stud (14) is raised. The viscous liquid (4) is placed in a sealed container (the reference numerals in parentheses are the reference numerals given in the same document, and so on).

  The high-viscosity liquid-sealed mount device disclosed in Patent Document 2 closes the opening of the container with a membrane-like lid (4) through which the stud (3) passes, and the damping plate (7) attached to the lower end of the stud (3) Is placed in a container filled with a highly viscous liquid (6), and a spring (9) is placed below the damping plate (7).

  In the liquid-enclosed suspension disclosed in Patent Document 3, the opening of the container is closed by a cylindrical laminated rubber (43) in which the stud (42) is slidable, and a damping plate (attached to the lower end of the stud (42) ( 50) is disposed in a container filled with a highly viscous liquid (60), and a spring (57) is disposed below the damping plate (50).

  In the liquid-sealed mounting device disclosed in Patent Document 4, the opening of the container is closed by a film-like lid (8) through which the stud (3) passes, and the movable damping plate (4) attached to the lower end of the stud (3). The fixed damping plate (10) surrounding the stud (3) is disposed in a container filled with the highly viscous liquid (2), and the spring (13) is disposed below the movable damping plate (4).

Japanese Patent Laid-Open No. 7-224883 (FIG. 1) JP-A-11-210807 (FIG. 1) JP-A-8-254241 (FIG. 5) JP2003-322198A (FIG. 1)

  In the liquid-sealed mount disclosed in Patent Document 1, the mount rubber (17) supports the load of the vibration isolator by the shear spring (shear deformation) of the mount rubber (17), and the horizontal direction of the vibration isolator. Is elastically constrained by the compression spring (compression deformation) of the mount rubber (17). In order to support the load of the vibration isolator, the mount rubber (17) needs to have a certain thickness in the vertical direction and be thin in the horizontal direction. Therefore, while the vibration in the vertical direction is absorbed by the shear deformation of the mount rubber (17), the vibration is attenuated by the stirring resistance of the highly viscous liquid by the damping plate (15), but the vibration in the vertical direction of the mount rubber (17) is reduced. Large strokes cannot be realized due to the large thickness. Further, the vibration in the horizontal direction is only absorbed by the compression deformation of the thin mount rubber (17), and the vibration is hardly attenuated. Therefore, the liquid-sealed mount disclosed in Patent Document 1 cannot achieve a large stroke, has a relatively low vertical vibration isolation, and a low horizontal vibration isolation.

  In the high-viscosity liquid-sealed mount device disclosed in Patent Document 2, the spring (9) supports the load of the vibration isolator, and the sliding rubber (7C) elastically moves the vibration isolator in the horizontal direction. Are restrained. Therefore, vibrations in the vertical direction are absorbed by the deformation of the spring (9), attenuated by the stirring resistance of the highly viscous liquid by the damping plate (7), and a large stroke is possible because the lid (4) is also a film. It is. On the other hand, the vibration in the horizontal direction is only absorbed by the compressive deformation of the thin sliding rubber (7C) abutting against the inner wall of the container, and the vibration is hardly attenuated. For example, the vibration is transmitted to the vehicle body side. That is, the high-viscosity liquid-sealed mount device disclosed in Patent Document 2 has low horizontal vibration isolation. Moreover, in order to suppress the twisting of the stud (3), it is necessary to limit the gap between the outer peripheral surface of the damping plate (7) and the inner wall surface of the container, so that the degree of freedom in setting the stirring resistance is limited. The

  In the liquid-filled suspension disclosed in Patent Document 3, the spring (57) supports the load of the vibration isolator, and the laminated rubber (43) elastically restrains the horizontal movement of the vibration isolator. ing. Therefore, the vibration in the vertical direction is absorbed by the deformation of the spring (57), attenuated by the stirring resistance of the highly viscous liquid by the damping plate (50), and the stud (42) slides against the laminated rubber (43). Because it is also free, a large stroke is possible. On the other hand, the vibration in the horizontal direction is absorbed by the compression deformation of the laminated rubber (43), and is attenuated by the stirring resistance of the highly viscous liquid (60) between the outer peripheral surface of the cylindrical portion of the damping plate (50) and the inner wall of the container. . However, since the stud (42) is restrained in the horizontal direction by the laminated rubber (43) obtained by laminating thin cylindrical rubber, the horizontal direction has a low vibration proofing property. For example, vibration is transmitted to the vehicle body side. End up. That is, the liquid-filled suspension disclosed in Patent Document 3 has high vibration isolation in the vertical direction, but low horizontal vibration isolation. Further, in order to prevent the stud (42) from rolling, the thickness (height) of the laminated rubber (43) is increased, and a rubber stopper (50) is provided between the laminated rubber (43) and the damping plate (50). 59), it is difficult to make this liquid-filled suspension compact in the vertical direction.

  In the liquid-sealed mounting device disclosed in Patent Document 4, the spring (13) supports the load of the vibration-damped body, and the fixed damping plate (10) has a predetermined gap with respect to the stud (3). When the stud (3) moves beyond a predetermined gap, the further movement is restricted. That is, the horizontal movement of the vibration isolator is not constrained until it contacts the inner peripheral surface of the fixed damping plate (10). Therefore, the vibration in the vertical direction is absorbed by the deformation of the spring (13), is attenuated by the stirring resistance of the movable damping plate (4), and a large stroke is possible because the lid (8) is also a film. On the other hand, in the horizontal direction, the stud (3) is only restrained only by the film-shaped lid (8), so that the horizontal vibration is almost not unless the stud (3) contacts the fixed damping plate (10). Although insulated, the flow resistance of the high-viscosity liquid (2) hardly occurs, so the horizontal vibration damping is low. That is, the liquid-sealed mount device disclosed in Patent Document 4 has high vibration isolation in the vertical direction, but is hardly restrained in the horizontal direction, so that vibration insulation is good, but vibration attenuation is low. That is, the horizontal vibration isolation is insufficient. Further, since the fixed damping plate (10) having a horizontal stopper function is provided between the lid (8) and the movable damping plate (4), the liquid-sealed mounting device is made compact in the vertical direction. Is difficult.

  In view of the circumstances as described above, an object of the present invention is to provide a liquid-filled mount capable of a large stroke, having high vibration-proofing properties in both the vertical and horizontal directions and being compact in the vertical direction. There is.

In order to achieve the above object, a liquid-filled mount according to an aspect of the present invention is attached between a first member and a second member, and prevents vibration input to the first member or the second member. A liquid-filled mount for shaking, comprising a cup-shaped container, a stud, a lid member, a holding member, a cylindrical elastic member, a buffer member, a highly viscous liquid, and a damping plate To do.
The cup-shaped container has an opening at the top and is attached to the first member.
The stud is disposed so as to be positioned at the center of the opening of the container and is attached to the second member.
The lid member has flexibility. The lid member is fixed to an upper portion of the stud, and is fixed to the opening so as to form a sealed chamber with the container.

  The holding member includes a flange portion and a holding cylindrical portion connected to the flange portion. The holding member is attached to the opening of the container with the outer peripheral edge of the lid member fixed thereto.

The cylindrical elastic member has an inner wall surface that is embedded in the holding cylindrical portion, extends downward in the axial direction from an outer peripheral edge portion of the lid member, and faces the stud.
The buffer member is disposed on the outer peripheral surface of the stud and has an outer peripheral surface facing the inner wall surface of the cylindrical elastic member with a predetermined interval.
The highly viscous liquid is sealed in the sealed chamber.

  The attenuation plate is disposed in the sealed chamber and attached to the stud so as to have a gap serving as a flow path that allows the liquid to flow between the inner wall of the container in a state of being immersed in the liquid.

  According to the present invention, since the stud is held by the flexible lid member, a large stroke is possible, and the cylindrical elastic member is added to the damping plate in the container in which the highly viscous liquid is sealed. The shock absorbing member is provided on the outer peripheral surface of the stud with a gap between the inner wall surface and the inner wall surface of the stud, so that vibration resistance in both the vertical and horizontal directions is high, and the cylindrical elastic member and the holding member are the shock absorbing members. Since it functions as a horizontal elastic stopper in cooperation with, a fixed damping plate is not required, and it can be made compact in the vertical direction.

In order to achieve the above object, a liquid-filled mount according to an aspect of the present invention is attached between a first member and a second member, and prevents vibration input to the first member or the second member. A liquid-filled mount for shaking, comprising a cup-shaped container, a stud, a lid member, a holding member, a cylindrical elastic member, a buffer member, a highly viscous liquid, and a damping plate To do.
The cup-shaped container has an opening at the top and is attached to the first member.
The stud is disposed so as to be positioned at the center of the opening of the container and is attached to the second member.
The lid member has flexibility. The lid member is fixed to an upper portion of the stud, and is fixed to the opening so as to form a sealed chamber with the container. Here, the upper portion of the stud indicates that it is located above the lower portion to which the attenuation plate is attached, but is preferably located further in the axial direction than the outer edge side attachment position of the lid member. .

  The holding member includes a flange portion and a holding cylindrical portion connected to the flange portion. The holding member is attached to the opening of the container with the outer peripheral edge of the lid member fixed thereto.

The cylindrical elastic member has an inner wall surface that is embedded in the holding cylindrical portion, extends downward in the axial direction from an outer peripheral edge portion of the lid member, and faces the stud. At this time, the holding cylindrical portion does not need to be completely embedded in the cylindrical elastic body, and a part thereof may be exposed on the inner wall surface side of the cylindrical elastic member.
The buffer member is disposed on the outer peripheral surface of the stud and has an outer peripheral surface facing the inner wall surface of the cylindrical elastic member with a predetermined interval.
The highly viscous liquid is sealed in the sealed chamber.

  The attenuation plate is disposed in the sealed chamber and attached to the stud so as to have a gap serving as a flow path that allows the liquid to flow between the inner wall of the container in a state of being immersed in the liquid.

  In the liquid-filled mount according to one aspect of the present invention, the vertical vibration is attenuated by the stirring resistance generated by stirring the highly viscous liquid in which the damping plate is sealed. Further, the vibration in the horizontal direction is caused by the vibration between the outer peripheral surface of the buffer member and the inner wall surface of the cylindrical elastic member facing the outer peripheral surface, that is, the space sandwiched between them (high viscosity In the horizontal direction). Due to the expansion and contraction of this space, the highly viscous liquid existing in this space is forced to flow along the outer peripheral surface of the buffer member and the inner wall surface of the cylindrical elastic member, and this flow resistance attenuates against horizontal vibration. Can be obtained.

Further, in the liquid-filled mount according to one aspect of the present invention, there is no need to provide a member that is a fixed attenuation plate as in the cited document 4 between the lid member and the attenuation plate, so the height in the vertical direction is lowered. Can be made compact in the vertical direction. That is, in the liquid-filled mount according to one aspect of the present invention, when the stud moves in the horizontal direction, the buffer member contacts the cylindrical elastic member, but the cylindrical elastic member and the holding member cooperate with the buffer member. Acts as a horizontal elastic stopper.
Furthermore, in the liquid-sealed mount according to an embodiment of the present invention, the stud is held by the flexible lid member, so that a large stroke is possible.
Therefore, the liquid-sealed mount according to one embodiment of the present invention can have a large stroke, has high vibration proof properties in both the vertical and horizontal directions, and can be made compact in the vertical direction.

  In the liquid-sealed mount according to an aspect of the present invention, the attenuation plate includes a disc portion fixed to the stud, and a cylindrical portion connected to the peripheral portion of the disc portion and along the inner wall of the container. The horizontal distance between the cylindrical elastic member and the buffer member may be shorter than the horizontal distance between the cylindrical portion and the container.

In the liquid-sealed mount according to one aspect of the present invention, a cylindrical portion having a large surface area in the vertical direction connected to the outer edge of the attenuation plate is provided, so that when the stud, that is, the attenuation plate moves in the horizontal direction, the attenuation plate High-viscosity liquid can be forced to flow even by the expansion and contraction of the gap (space) between the cylindrical part of the container and the inner wall of the container, and a larger amount of high-viscosity liquid can be generated in the horizontal direction. Can be obtained.
In addition, by shortening the horizontal distance between the cylindrical elastic member and the buffer member relative to the horizontal distance between the cylindrical portion and the container, the buffer member can prevent the cylindrical elastic member from moving in the horizontal direction of the stud. Since the cylindrical portion does not contact the inner wall of the container elastically in contact with the inner wall surface, the contact between the cylindrical portion of the damping plate and the inner wall surface of the container can be regulated, and the buffer member can be Since it can adhere | attach, stronger attenuation | damping property can be produced.

  In the liquid filled mount according to one aspect of the present invention, the holding member is an outer peripheral end of the lid member, and an upper portion of the holding cylindrical portion is connected to the flange portion, and the holding cylindrical portion and the flange member are connected to each other. The part may be R-shaped.

In the liquid-sealed mount according to an aspect of the present invention, the connection portion between the flange portion and the holding cylindrical portion is formed in an R shape, and the outer edge portion of the lid member connected to the upper portion of the stud is fixed to the R-shaped connection portion. Thus, the lid member can be formed into an arch shape. Accordingly, when the lid member is greatly bent upward, the difference in elongation between the upper surface and the lower surface of the lid member can be reduced, and therefore, the lid member is hardly broken.
In addition, when the stud is twisted, a part of the lid member receives a force so as to stretch against the connection surface of the connection portion. At that time, the connection surface has an R shape, so that local stress is applied. Concentration does not easily occur, and peeling of the lid member and the holding member and destruction of the lid member can be prevented.

  In the liquid filled mount according to an aspect of the present invention, a spring may be disposed between the lower surface of the attenuation plate and the bottom wall of the container, and the attenuation plate may be supported by the spring.

  In the liquid-filled mount according to one aspect of the present invention, the load in the vertical direction is received by the spring, so that the lid member can be a thin film, can be made more flexible, and vibration insulation is improved. Further, the vibration in the vertical direction can be absorbed by the deformation of the spring and can be damped by the stirring resistance of the highly viscous liquid by the damping plate, and can cope with a large stroke.

  In the liquid-sealed mount according to an aspect of the present invention, the buffer member and the attenuation plate have a through hole that allows the liquid to flow between the upper surface side of the buffer member and the lower surface side of the attenuation plate. May be.

In the liquid-sealed mount according to one aspect of the present invention, when the attenuation plate rises and the pressure below the lid member in the container becomes high, the through hole can release the pressure to the lower side of the attenuation plate. That is, when the space formed by the lower surface of the lid member and the upper surface of the buffer member becomes extremely narrow, it functions as a bypass that releases the high-viscosity liquid sealed in this space under the attenuation plate. Therefore, the lid member is not destroyed by the pressure increase in the space.
Further, when the damping plate descends and a negative pressure is generated in the space formed by the lower surface of the lid member and the upper surface of the buffer member, the highly viscous liquid is sucked into the space from the lower portion of the damping plate. The pressure of the highly viscous liquid does not drop extremely. Therefore, even if the lid member is made of a thin film, it does not buckle, so that it is possible to prevent breakage due to pinching when it is displaced in the horizontal direction.
In the liquid-sealed mount according to an aspect of the present invention, the buffer member may be provided with a groove on the outer peripheral surface of the buffer member. For example, the groove may be provided in the vertical direction or the circumferential direction of the outer peripheral surface of the buffer member, or may be provided in a spiral shape on the outer peripheral surface of the buffer member.
In the liquid-sealed mount according to one aspect of the present invention, by providing a groove on the outer peripheral surface of the buffer member, deformation of the buffer member escapes into the groove when the buffer member and the cylindrical elastic member are brought into contact with each other. It is possible to improve the performance of cushioning the impact upon contact, that is, the cushioning property. For example, in the liquid-filled mount according to one aspect of the present invention, as described above, when the stud moves in the horizontal direction, the buffer member contacts the cylindrical elastic member, and the cylindrical elastic member and the holding member buffer. It functions as a horizontal elastic stopper in cooperation with the member. Therefore, if the height of the buffer member is increased, the contact area between the buffer member, the cylindrical elastic member, and the holding member is increased, and the performance as the horizontal elastic stopper can be improved.
Further, by providing the groove on the outer peripheral surface of the buffer member, the outer diameter of the buffer member can be enlarged while maintaining the cushioning property and the fluidity of the highly viscous liquid. For example, when the outer peripheral surface of the buffer member whose outer diameter is enlarged is lightly in contact with the cylindrical elastic member, it receives a light reaction force, so that the stud functions as a guide for maintaining the radial center position. . Therefore, if the height of the buffer member is increased, even if the stud is greatly displaced in the vertical direction, the contact between the buffer member and the cylindrical elastic member can be maintained, so that the function of the stud as a guide can be maintained. it can.
Further, in the liquid-sealed mount according to one aspect of the present invention, by providing a groove in the vertical direction of the outer peripheral surface of the buffer member, the flow of the highly viscous liquid when the stud and the buffer member vibrate in the vertical direction is not hindered. Can be. Furthermore, when the stud is greatly displaced in the horizontal direction and comes into strong contact with the cylindrical elastic member, the highly viscous liquid in the groove is discharged in the vertical direction along the groove by crushing the vertical groove. Since it becomes a complicated flow of flowing to the back side of the stud, it is possible to cause stronger damping.
In the liquid filled mount according to one aspect of the present invention, the groove is provided in a vertical direction of the outer peripheral surface of the buffer member, and the attenuation plate is located at a position corresponding to the groove provided on the outer peripheral surface of the buffer member. At least one or more through holes may be arranged to allow the liquid to flow. As a result, liquid can flow between the space formed on the lower surface of the lid member and the upper surface of the buffer member and the space below the damping plate via the groove provided on the outer peripheral surface of the buffer member and the through hole. It becomes. Therefore, when the damping plate rises and the pressure below the lid member in the container becomes high, the pressure can be released to the lower part of the damping plate, and the lid member is not broken by the pressure rise. Further, when the damping plate descends and a negative pressure is generated in the space formed by the lower surface of the lid member and the upper surface of the buffer member, the highly viscous liquid is sucked into this space from the lower portion of the damping plate. The pressure of the highly viscous liquid does not drop extremely. Therefore, even if the lid member is made of a thin film, it is difficult to buckle, so that it is possible to prevent breakage due to pinching when displaced in the horizontal direction.
In the liquid-filled mount according to an aspect of the present invention, a gap may be provided between the lower surface of the buffer member and the upper surface of the attenuation plate.
In the liquid-sealed mount according to one aspect of the present invention, when a shift occurs between the groove provided on the outer peripheral surface of the buffer member and the through hole of the attenuation plate, the flow of the liquid is inhibited. If there is a gap between the lower surface of the buffer member and the upper surface of the damping plate, the liquid can be circulated through the gap even if a slight positional deviation occurs. Therefore, when assembling the liquid-filled mount, not so much accuracy is required for the positioning of the buffer member and the damping plate, and the workability during assembly can be improved.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a cross-sectional view showing a configuration of a liquid-filled mount according to an embodiment of the present invention. FIG. 2 is a top view showing the configuration of the liquid-sealed mount. 2 is a cross-sectional view of FIG. 1 as viewed in the direction of the arrow with respect to the AA cross section in FIG.

  As shown in these drawings, the liquid-filled mount 1 includes a cup-shaped container 10, a stud 20, a flexible sealing lid 30 as a lid member, a holding member 40, a cylindrical elastic member 50, The buffer member 60, the highly viscous liquid 70, the damping plate 80, and the spring member 90 are included.

  The cup-shaped container 10 is made of, for example, metal, has a bottom wall 11 at the bottom, and an opening 12 at the top. The container 10 has a flange portion 14 provided with a mounting through hole 13 on the outer periphery of the opening portion 12. A convex portion 17 is provided at a central portion in the radial direction (X direction in the drawing) of the bottom wall 11. The convex portion 17 positions the spring member 90 and prevents the spring member 90 from being displaced.

  The stud 20 is disposed so as to be positioned in the central portion (the axial line of the container 10) in the radial direction (X direction in the drawing) of the container 10. The stud 20 is made of, for example, metal, protrudes to the outside from the opening 12 side of the container 10, and is provided with a mounting screw hole 21 at its upper end, and the mounting screw hole 21 is a vehicle as a second member, for example. The engine (not shown) is connected. An attenuation plate 80 is fixed to the lower end of the stud 20 by a caulking portion 24.

  The flexible sealing lid 30, the holding member 40, and the cylindrical elastic member 50 are configured by a molded member 100 that is integrally molded by vulcanization molding, for example, together with the stud 20. The molding member 100 is fixed to the opening 12 so as to form a sealed chamber 110 with the inner wall 15 of the container 10. The flexible sealing lid 30 and the cylindrical elastic member 50 are made of, for example, a rubber material, and the holding member 40 is made of, for example, metal.

  The flexible sealing lid 30 is an upper portion of the molding member 100, and includes a central thin film portion 31 and an upper stopper portion 32. The thin film portion 31 includes, for example, a center hole 31A and an outer peripheral edge portion 31B (see FIG. 1, the center hole 31 </ b> A and the upper portion of the stud 20 are fixed by, for example, vulcanization adhesion so as to be liquid-tight, and the outer peripheral edge 31 </ b> B is described later. The holding member 40 is fixed by, for example, vulcanization adhesion. Here, the lower surface 31C of the thin film portion 31 is fixed to the stud 20 on the inner peripheral side (center hole 31A side), which is one end, and to the holding member 40 described later on the other end side (outer peripheral edge portion 31B side). It is preferable that the substantially convex arch shape is formed from the stud 20 to the holding member 40, and the top portion of the substantially arch-shaped lower surface 31 </ b> C is preferably located above the upper surface of the holding member 40. . Thereby, it becomes difficult to be restrained by the fixation between the stud 20 and the holding member 40, and the deformation can be made more flexibly. When the stud 20 or the container 10 receives a load in the vertical direction from a vibration isolator (for example, a vehicle body or an engine) (not shown), the thin film portion 31 is fixed to the center portion or the container 10 (the holding member 40). ) Is fixed to the outer peripheral edge 31B. In other words, the thin film portion 31 has a function of allowing the deviation of the stud 20 and the container 10 to be deflected and sealing the container 10 and the stud 20 in a liquid-tight manner.

  The holding member 40 includes a flange portion 41 and a holding cylindrical portion 42 that is connected to the flange portion 41 and extends in the axial direction (Y direction). For example, at the outer peripheral end of the flexible sealing lid 30, the upper portion of the holding cylindrical portion 42 is connected to the flange portion 41, and the connecting portion 43 between the holding cylindrical portion 42 and the flange portion 41 has a large R without having a corner portion. The outer peripheral edge portion 31 </ b> B of the thin film portion 31 of the flexible sealing lid 30 is fixed to the connection portion 43. Since the connection portion 43 has an R shape, for example, the upper surface side of the outer peripheral edge portion 31B is fixed to the flange portion 41 across the connection portion 43, and the lower surface side of the outer peripheral edge portion 31B is the inner side of the holding cylindrical portion 42. Since it is fixed to the wall surface, the thin film portion 31 is connected so as to extend upward from the outer peripheral edge portion 31B toward the inner diameter side. Therefore, when the stud 20 receives a twisting load, even if a compressive load is applied to one flexible sealing lid 30, the flexible sealing lid 30 is stretched against the arched connection surface of the connection portion 43. Because of the force, folding of the thin film portion 31 due to buckling is difficult to occur. Further, even if the thin film portion 31 of the flexible sealing lid 30 made of rubber is folded, it is difficult to be sandwiched between the stud 20 and the holding member 40, so that it is difficult to break. At this time, since the outer peripheral edge portion 31B of the thin film portion 31 is connected to the R-shaped portion of the connection portion 43, extreme stress concentration does not occur at one of the upper surface end or the lower surface end of the outer peripheral edge portion 31B. The outer peripheral edge portion 31 </ b> B is difficult to peel from the surface of the holding member 40. The flange portion 41 is exposed toward the outer periphery from the flexible sealing lid 30 and the cylindrical elastic member 50, is overlapped with the flange portion 14 of the container 10, and is crimped and fixed by the crimping piece 16. The flange portion 41 is provided with a mounting through hole 44 that is coaxial with the mounting through hole 13 of the flange portion 14. The flange portions 14 and 41 are disposed, for example, at predetermined positions of the vehicle body, and are fixed by bolts (not shown) through the mounting through holes 44 and 13.

  The cylindrical elastic member 50 is a lower portion of the molded member 100 and has a cylindrical shape. The cylindrical elastic member 50 is embedded with a holding cylindrical portion 42, and extends from the outer peripheral edge portion 31 </ b> B of the flexible sealing lid 30 along the inner wall 15 of the container 10 downward in the axial direction (Y direction in the drawing). 20 has an inner wall surface 51 that faces 20. Here, since the holding cylindrical portion 42 is embedded in the cylindrical elastic member 50, the rubber made as the cylindrical elastic member 50 is formed between the outer periphery of the holding cylindrical portion 42 and the vicinity of the opening 12 of the inner wall 15 of the container 10. The member is compressed and interposed, and the sealing performance of the sealed chamber 110 is improved. Even if the stud 20 strongly abuts against the inner wall surface 51 via a buffer member 60 described later, since the holding cylindrical portion 42 is built in, the sealing property between the holding cylindrical portion 42 and the inner wall 15 of the container 10 is improved. Since there is no influence, the highly viscous liquid does not leak from between the container 10 and the molded member 100.

  The buffer member 60 is disposed on the outer peripheral surface 22 below the stud 20 and has an outer peripheral surface 61 that faces the inner wall surface 51 of the cylindrical elastic member 50 with a predetermined distance d1. The buffer member 60 is made of, for example, rubber and has a ring shape, and has a convex portion 63 on the inner peripheral surface 62. The buffer member 60 is fitted and fixed at a predetermined position of the stud 20 by fitting the convex portion 63 into the concave groove 23 provided on the outer peripheral surface 22 of the stud 20. The buffer member 60 is housed in a housing recess 82 provided on the upper surface 81 of the attenuation plate 80 and is positioned and fixed in the X direction. The height (thickness) h <b> 1 of the buffer member 60 is such that the liquid-filled mount 1 is incorporated in a vibration isolator (not shown) and is stationary (hereinafter referred to as neutral state) with the upper surface 81 of the damping plate 80. The distance h2 from the lower surface 52 of the cylindrical elastic member 50 is longer than that of the lower surface 52, that is, h3 is the region where the outer peripheral surface 61 of the buffer member 60 and the inner wall surface 51 of the cylindrical elastic member 50 face each other. Further, by providing a taper at the corner of the ring-shaped buffer member 60, the highly viscous liquid 70 flows smoothly in the vicinity thereof.

The highly viscous liquid 70 is enclosed in the sealed chamber 110. For example, air 71 is enclosed in the sealed chamber 110 together with the highly viscous liquid 70. By not filling the sealed chamber 110 with the liquid 70 and leaving air or actively injecting air, the displacement of the volume due to the injection amount error of the liquid 70 and the dimensional error of each component is absorbed. It becomes easy. Further, by pressurizing the air 71 to a predetermined pressure and enclosing it in the sealed chamber 110 together with the high-viscosity liquid 70, the high-viscosity liquid 70 can be brought into a pressurized state, suppressing the occurrence of cavitation, and vibrating. It is possible to further improve the basic attenuation performance of attenuation. Of course, the sealed chamber 110 may be configured to be fully filled with the liquid 70. In addition, the viscosity of the highly viscous liquid is appropriately selected according to the required characteristics. However, particularly when used as a vibration-proof mount for an internal combustion engine or a cab mount for an industrial machine, the viscosity is 5 A viscous liquid in the range of 5,000 to 50,000 mm ² / s (5,000 to 50,000 cSt) is preferred.

The attenuation plate 80 is disposed in the sealed chamber 110 so as to have a gap d2 that becomes a flow path that allows the liquid 70 to flow between the inner wall 15 of the container 10 in a state where the attenuation plate 80 is immersed in the liquid 70. The crimping portion 24 provided on the stud 20 is crimped. The damping plate 80 is made of, for example, metal, and is connected to the disc portion 83 fixed to the stud 20 and the peripheral portion 84 of the disc portion 83, and the cylindrical portion 85 that extends downward along the inner wall 15 of the container 10. The distance d1 which is the horizontal distance between the cylindrical elastic member 50 and the buffer member 60 is shorter than the horizontal distance d2 between the cylindrical portion 85 and the container 10 (d1 <d2). Thereby, the buffer member 60 elastically contacts the inner wall surface 51 of the cylindrical elastic member 50 against the horizontal movement of the stud 20, and the cylindrical portion 85 does not contact the inner wall 15 of the container 10. The function as a horizontal elastic stopper can be obtained reliably. The diameter of the disk portion 83 of the damping plate 80 is longer than the inner diameter of the cylindrical elastic member 50. When the damping plate 80 rises, the upper surface 81 of the damping plate 80 contacts the lower surface 52 of the cylindrical elastic member 50, and It functions as a stopper.
The spring member 90 is a metal coil spring, for example, and is disposed between the lower surface 86 of the damping plate 80 and the bottom wall 11 of the container 10, and serves as a second member attached to the damping plate 80, that is, the stud 20. For example, supporting a vehicle engine.

  In the liquid-filled mount 1 of this embodiment, when the stud 20 or the container 10 inputs vertical vibration from a vibration-proof body (for example, a vehicle body or an engine) not shown, the vertical vibration is caused by deformation of the spring member 90. Absorbed and attenuated by the stirring resistance of the damping plate 80. Further, when the stud 20 or the container 10 receives horizontal vibration from a vibration isolator (for example, a vehicle body or an engine) (not shown), the outer peripheral surface 61 of the buffer member 60 and the cylindrical elastic member 50 are caused by the vibration. The space d1 between the wall surfaces 51, that is, the space C1 sandwiched between them (the highly viscous liquid 70 exists) expands and contracts. Due to the expansion / contraction of the space, the highly viscous liquid 70 existing in the space C1 is forced to flow, and attenuation against horizontal vibration can be obtained. That is, in the liquid-filled mount 1 of the present embodiment, basically, the gap d2 between the outer wall of the cylindrical portion 85 of the attenuation plate 80 and the inner wall 15 of the container 10 opposed thereto, that is, the space C2 (between them) The high-viscosity liquid 70 is forced to flow due to the expansion and contraction of the high-viscosity liquid 70, so that damping against horizontal vibration is obtained. By providing the cylindrical elastic member 50 and the buffer member 60, Further vibration isolation can be obtained with respect to the direction.

Further, in the liquid-filled mount 1 of the present embodiment, when the stud 20 moves in the horizontal direction, the buffer member 60 contacts the cylindrical elastic member 50, but the cylindrical elastic member 50 and the holding member 40 are the buffer member. In cooperation with 60, it functions as a horizontal elastic stopper. That is, in the liquid-filled mount 1 of the present embodiment, the holding member 40 is provided in addition to the cylindrical elastic member 50 and the buffer member 60, so that the There is no need to provide such a member as a fixed damping plate, the height in the vertical direction can be reduced, and the size in the vertical direction can be reduced.
Further, in the liquid-filled mount 1 of this embodiment, the buffer member 60 is arranged on the outer peripheral surface of the stud 20 and is opposed to the cylindrical elastic member 50. Therefore, by changing the radial thickness of the buffer member 60, The distance d1, that is, the radial position of the space C1 can be adjusted. Thus, the volume of the space C1 is increased by arranging the space C1 radially outward in the container 10 while maintaining the distance d1, that is, the displacement distance allowed in the horizontal direction of the stud 20. And the attenuation caused by expansion / contraction of the space C1 can be increased.
Furthermore, in the liquid-filled mount 1 of this embodiment, the stud 20 is held by the flexible sealing lid 30, so that a large stroke is possible.

  Therefore, the liquid-filled mount 1 of this embodiment can have a large stroke, has high vibration proofing properties in both the vertical and horizontal directions, and can be made compact in the vertical direction.

  Further, the buffer member 60 separates the sealed chamber 110 into an upper chamber and a lower chamber via a gap between the outer peripheral surface 61 of the buffer member 60 and the inner wall surface 51 of the cylindrical elastic member 50, and the gap Thus, the flow of the liquid 70 can be controlled between the upper chamber and the lower chamber. Accordingly, by appropriately setting the height of the buffer member 60, the interval d1, and the like, the liquid 70 from the upper chamber to the lower chamber is set so as not to apply a high pressure to the flexible sealing lid 30 in synchronism with the rise of the attenuation plate 80, for example. By controlling the flow of this, it is possible to prevent a high pressure from being applied to the flexible sealing lid 30, and it is possible to extend the life of the flexible sealing lid 30 and prevent swelling. Further, the above-described distance d1, the height of the buffer member 60, and the surface of the buffer member 60 are formed with vertical grooves that do not affect the attenuation in the horizontal direction, and the buffer member 60 has an elliptical shape when viewed from above. Since a desired flow resistance can be obtained by configuring or the like, the degree of freedom in design increases.

  Moreover, the liquid-filled mount 1 of this embodiment is in a neutral state between, for example, the stud 20 to which the engine as the second member is connected and the container 10 to which the vehicle body as the first member is connected. Sometimes, only the thin film portion 31 and the spring member 90 of the flexible sealing lid 30 are interposed. That is, between the stud 20 and the container 10, the vibration of the stud 20 in the horizontal direction (X direction in the drawing) is only a thin rubber, which makes it difficult for the horizontal vibration to be transmitted.

Next, another embodiment of the present invention will be described.
FIG. 3 is a cross-sectional view showing a configuration of a liquid-filled mount according to another embodiment of the present invention.
As shown in FIG. 3, in the liquid-sealed mount 1 according to this embodiment, the buffer member 60 and the attenuation plate 80 can circulate the liquid 70 between the upper surface side of the buffer member 60 and the lower surface side of the attenuation plate 80. Through holes 67 and 87 are provided.
Thereby, when the attenuation plate 80 rises and the space formed by the lower side of the flexible sealing lid 30 in the container 10 and the upper surface of the buffer member 60 becomes high pressure, the through holes 67 and 87 are Functions as a bypass that escapes to the space below the low-pressure damping plate 80.
For example, it is possible to prevent a high pressure from being applied to the flexible sealing lid 30, and it is possible to extend the life of the flexible sealing lid 30 and prevent swelling. In addition, the liquid 70 is suppressed from becoming hard due to the high pressure, and it is difficult for the minute vibrations to be transmitted through the liquid 70, so that the vibration-proof property against the minute vibrations is improved.
Further, by providing the through hole 67 inward of the buffer member 60, a desired flow resistance can be obtained by appropriately selecting the size and number of pressure adjustments without affecting the horizontal attenuation. In some cases, the degree of freedom in design increases.

Next, still another embodiment of the present invention will be described.
FIG. 4 is a cross-sectional view showing a configuration of a liquid-filled mount according to still another embodiment of the present invention.
As shown in FIG. 4, the liquid-filled mount 1 according to this embodiment has a metal cylindrical member 33 embedded in an upper stopper 32 of a flexible sealing lid 30.
In this case, for example, a metal flange 34 exposed toward the outer periphery is connected to the lower portion of the cylindrical member 33, the flange 34 is brought into contact with the flange 41 of the holding member 40, and together with the flange 14 of the container 10, The crimping piece 16 is used to fix it.
Further, the flange portion 34 is provided with mounting through holes 35 that are coaxial with the mounting through holes 13 and 44 of the flange portions 14 and 41, and the flange portions 34, 14, and 41 are disposed at predetermined positions of the vehicle body, for example. Then, it is fixed by bolts (not shown) through the mounting through holes 35, 44, 13.
In this way, by embedding the metal cylindrical member 33 in the upper stopper 32 of the flexible sealing lid 30, the stud 20 can be prevented from being twisted, and the upper stopper 32 of the flexible sealing lid 30 is deformed. The thin film portion 31 extending from the base position of the upper stopper 32 becomes difficult to be affected by the deformation of the upper stopper 32, so that it can be formed thinner and the softness is improved.
Next, another embodiment of the present invention will be described.
FIG. 5 is a cross-sectional view showing a configuration of a liquid-sealed mount according to still another embodiment of the present invention,
6 is a cross-sectional view taken along the line BB in the liquid-filled mount shown in FIG.
In the liquid-filled mount 1 shown in these drawings, as described above, when the stud 20 or the container 10 moves in the horizontal direction (X direction in FIG. 5), the buffer member 60 contacts the cylindrical elastic member 50. The cylindrical elastic member 50 and the holding cylindrical portion 42 cooperate with the buffer member 60 to function as a horizontal elastic stopper. Therefore, in the liquid-filled mount 1 according to this embodiment, the contact area between the buffer member 60 and the cylindrical elastic member 50 is increased by increasing the height of the buffer member 60 as compared to the above-described embodiment. The size is increased to improve the performance as a horizontal elastic stopper. However, when the contact area between the buffer member 60 and the cylindrical elastic member 50 is increased as described above, the cushioning property at the time of contact between the buffer member 60 and the cylindrical elastic member 50 is lowered. Therefore, in the liquid-sealed mount 1 according to the present embodiment, a plurality of grooves 66 are provided, for example, at equal intervals in the vertical direction (Y direction in FIG. 5) of the outer peripheral surface 65 of the buffer member 60 whose height is increased. When the buffer member 60 and the cylindrical elastic member 50 come into contact with each other, the deformation of the buffer member 60 escapes to the groove 66, and the performance of cushioning the impact at the time of contact, that is, the cushioning property can be improved. Therefore, in the liquid-filled mount 1 according to this embodiment, the cushioning property can be improved while improving the function as a horizontal elastic stopper. In addition, as the groove | channel 66 for improving cushioning property, you may provide in the circumferential direction of the outer peripheral surface 65 of the buffer member 60, may be provided in the outer peripheral surface 65 of the buffer member 60 in a spiral shape, A combination of these may also be used. In addition, by providing the groove 66 in the outer peripheral surface 65 of the buffer member 60, when the outer diameter of the buffer member 60 is expanded while maintaining cushioning properties, the radial position of the stud 20 is maintained. It can also function as a guide.
In addition, the attenuation plate 80 according to the present embodiment is provided with through holes 88 that allow the liquid 70 to flow in positions corresponding to the grooves 66 provided in the outer peripheral surface 65 of the buffer member 60. In this liquid-sealed mount 1, the lower surface of the flexible sealing lid 30 and the upper surface of the buffer member 60 are formed via the groove 66 and the through hole 88 provided on the outer peripheral surface 65 of the buffer member 60. The liquid 70 can flow between the space and the space below the attenuation plate 80. Therefore, when the damping plate 80 rises and the pressure below the flexible sealing lid 30 in the container 10 becomes high, the pressure can be released to the lower portion of the damping plate 80 through the through hole 88. The flexible sealing lid 30 is not broken by the pressure increase. Further, when the attenuation plate 80 is lowered and negative pressure is generated in the space formed by the lower surface of the flexible sealing lid 30 and the upper surface of the buffer member 60, the lower portion of the attenuation plate 80 is inserted through the through hole 88. Since the liquid 70 is sucked into the space (the space formed by the lower surface of the flexible sealing lid 30 and the upper surface of the buffer member 60), the pressure of the liquid 70 in this space does not extremely decrease. Therefore, even if the flexible sealing lid 30 is made thinner, it does not buckle, so that when it is displaced in the horizontal direction, the film of the buckled flexible sealing lid 30 is between the buffer member 60 and the cylindrical elastic member 50. It can be prevented from being sandwiched and destroyed.
In the liquid-filled mount 1 according to the present embodiment, a gap 120 is provided between the lower surface of the buffer member 60 and the upper surface of the attenuation plate 80. As described above, when the position of the groove 66 provided in the outer peripheral surface 65 of the buffer member 60 and the through hole 88 provided in the attenuation plate 80 are displaced, the flow of the liquid 70 is hindered. If there is a gap 120 between the lower surface of the buffer member 60 and the upper surface of the damping plate 80, the liquid 70 can be circulated through the through-hole 88 through the gap 120 even if a slight positional deviation occurs. Therefore, when assembling the liquid-filled mount 1, so much accuracy is not required for alignment between the buffer member 60 and the attenuation plate 80, and workability during assembly can be improved.
Furthermore, in the liquid-filled mount 1 according to this embodiment, the lower outer peripheral end 18 of the cup-shaped container 10 has a large taper shape, and the convex portion 17 at the center of the bottom surface of the container 10 is greatly raised toward the inside of the container. By adopting the shape, the amount of the liquid 70 accommodated in the container 10 can be reduced.
In the liquid-sealed mount 1 according to this embodiment, the cylindrical elastic member 50 and the holding cylindrical portion 42 function as horizontal elastic stoppers in cooperation with the buffer member 60, so that the height of the buffer member 60 is increased. Although it was made high, a function as a horizontal direction elastic stopper can be improved by lengthening the overlap of the holding | maintenance cylindrical part 42 with respect to the buffer member 60 substantially. For example, as shown in FIG. 7, the connection portion 43 between the holding cylindrical portion 42 and the flange portion 41 is formed into a small R shape that is close to a corner, thereby overlapping the holding cylindrical portion 42 with the buffer member 60. Can be substantially longer. Further, as shown in FIG. 8, the connecting portion 43 between the holding cylindrical portion 42 and the flange portion 41 is a slope having a small upward opening angle, thereby substantially overlapping the holding cylindrical portion 42 with the buffer member 60. Can be long. Furthermore, as shown in FIG. 9, the overlapping portion of the holding cylindrical portion 42 with respect to the buffer member 60 is made substantially longer by making the connecting portion 43 of the holding cylindrical portion 42 and the flange portion 41 have a very large R shape. Can do.

The present invention is not limited to the above-described embodiment, and can be implemented with various modifications. The scope of the modifications also belongs to the technical scope of the present invention.
In the said embodiment, although the buffer member was manufactured with the rubber material from the ease of an assembly etc., it is not limited to this, For example, you may use resin elastomer etc., for example. Moreover, although the buffer member is ring-shaped, other shapes may be used. Here, the distance d1 that is the horizontal distance between the cylindrical elastic member and the buffer member is constant with respect to the circumferential direction, that is, the distance d1 that is the distance between the front and rear direction and the left and right direction in the horizontal direction when the buffer member is circular. Although it may be constant, for example, by making the distance d1 as these distances different, it is possible to obtain different attenuation performance in the left-right direction and the front-rear direction. In that case, the buffer member may be, for example, an oval shape so that the thickness in the front-rear direction and the thickness in the left-right direction are different, and the distance d1 that is the distance between them may be different. The distance d1, which is these distances, may be different by making the thicknesses different. Alternatively, both the buffer member and the cylindrical elastic member may have different thicknesses.

  In the said embodiment, although the flexible sealing lid, the holding member, and the cylindrical elastic member showed the example comprised by the shaping | molding member integrally shape | molded by vulcanization molding with a stud, some of these members or Of course, the whole structure may be assembled after molding or the like.

  In the above embodiment, the attenuation plate has an inverted cup shape, but it is needless to say that the attenuation plate may have another shape such as a flat plate shape. The damping plate may be attached to the stud with some play.

  In the above embodiment, the spring is arranged between the lower surface of the damping plate and the bottom wall of the container to support the damping plate. However, other elastic materials such as rubber may be used instead of the spring. Alternatively, such a support member may not be provided on the lower surface of the attenuation plate.

  In the above embodiment, the case where the flange portion of the container and the flange portion of the molded member are integrated in a liquid-tight manner by bending the flange portion (claw for joint fastening) provided at the upper end portion of the cup-shaped container has been shown. However, the present invention is not limited to the use of the joint claws, and it is needless to say that it may be liquid-tightly integrated by means such as welding. Further, although the attenuation plate is caulked and fixed to the lower end of the stud, it may be fixed using bolts, welding, or adhesion.

  In the above embodiment, the connecting portion of the flange portion and the holding cylindrical portion is formed in an R shape, the outer edge portion of the lid member connected to the upper portion of the stud is fixed to the R-shaped connecting portion, the lid member is formed in an arch shape, and the lid When the member is largely bent upward, it is configured to prevent breakage by providing a stopper function that reduces the difference in elongation between the upper surface and the lower surface of the lid member. However, as shown in FIG. The convex portion 45 is provided so as to have an upward inclined surface from the vicinity of the flange portion 41 of the connecting portion 43 to the flange portion 41, and the bending from the flexible sealing lid 30 is received by this inclined surface. The stopper function may be reinforced. Accordingly, even if the overlapping position of the holding cylindrical portion 42 with respect to the buffer member 60 is extended to near the position of the downward recess of the lower surface of the flexible sealing lid 30, Can be maintained.

  In the embodiment shown in FIGS. 5 and 6, the lower outer peripheral end 18 of the cup-shaped container 10 has a large taper shape, and the convex portion 17 at the center of the bottom surface of the container 10 is greatly raised toward the inside of the container. Thus, the amount of the liquid 70 accommodated in the container 10 is reduced, but as shown in FIG. 11, when the attenuation plate 80 is at the lowermost stroke end, By configuring so that the position of the bottom wall 11 at the bottom of the cup-shaped container 10 is raised so that the lower end portion does not contact the bottom wall 11, the amount of the liquid 70 accommodated in the container 10 is further reduced. And more compact.
