  The present invention relates to a fluid-filled vibration-proof mount and a method for manufacturing the same.

A conventional fluid-filled vibration-proof mount is disclosed in, for example, Patent Document 1 as shown in FIG. The fluid-filled vibration-proof mount shown in FIG. 5 employs a caulking structure in order to integrally fix the mount component or the support member of the mount component. Specifically, the diaphragm support member located on the outermost peripheral side is used for caulking, and other support members (support members such as a main rubber elastic body and a vibration plate) are used for caulking. The caulking support member is formed in a substantially cylindrical shape as a whole, and has a shape in which the caulking portion on the lower end side protrudes to the outer peripheral side by bending.
JP 2005-188581 A

  However, the caulking portion of the caulking support member has a shape that protrudes by bending to the outer peripheral side, so that the outer diameter of the fluid-filled vibration-proof mount is enlarged. When examined in more detail, the caulking portion of the caulking support member has a cylindrical end portion bent toward the outer peripheral side, and the end portion is further bent into a cylindrical shape (lower side in FIG. 5). Yes. That is, the portion bent toward the outer peripheral side is a portion that engages with the caulking support member. In addition, the formation of the portion engaged with the caulking support member by bending as described above is a factor that enlarges the outermost diameter of the fluid-filled vibration-proof mount.

  The present invention has been made in view of such circumstances, a plurality of members can be integrally fixed by caulking without forming a portion engaged with a support member for caulking by bending, And it aims at providing the fluid enclosure type vibration isolating mount which can achieve size reduction of an outermost diameter.

  The fluid-filled vibration-proof mount of the present invention is a fluid-filled vibration-proof mount having a plurality of integral fixing members, and the first integral fixing member, which is any one of the plurality of integral-fixing members, is a first caulking. A member and a second caulking member are provided. The first caulking member has a cylindrical shape, and is a member having a support end surface that engages with a second integral fixing member, which is at least one of the other integral fixing members, in the cylindrical axis direction. The second caulking member has a cylindrical shape, is joined to the outer peripheral side of the first caulking member, and is a member that clamps the second integral fixing member between the supporting end surface of the first caulking member in the cylinder axial direction by caulking. .

  Here, the integral fixing member supports the main rubber elastic body connected to the first attachment member attached to one member to be vibration-proof connected and the second attachment member attached to the other member to be vibration-proof connected. A pressure receiving chamber forming member for forming a pressure receiving chamber in which an incompressible fluid is sealed between the elastic body supporting member and the main rubber elastic body, and the pressure receiving chamber via the orifice passage, and incompressible These are a plurality of members that are integrally fixed to a diaphragm support member that supports a diaphragm that forms a variable volume equilibrium chamber in which a fluid is sealed.

  Alternatively, the integral fixing member supports the main rubber elastic body connected to the first attachment member attached to one member to be vibration-proof connected and the second attachment member attached to the other member to be vibration-proof connected. A vibration receiving plate supporting member that forms a pressure receiving chamber in which an incompressible fluid is sealed is formed between the elastic body supporting member and the main rubber elastic body, and supports a displaceable vibration plate; An actuator supporting member that supports an electromagnetic actuator that vibrates and displaces the plate, and a diaphragm that communicates with the pressure receiving chamber through an orifice passage and supports a diaphragm that forms a variable volume equilibrium chamber in which an incompressible fluid is enclosed. It is a several member fixed integrally among a support member.

  In addition, the fluid-filled vibration-proof mount in the case where the integrated fixing member is the former includes the case of a so-called non-active fluid-filled vibration-proof mount and the case of a part of the active fluid-filled vibration-proof mount. become. Further, the fluid-filled vibration-proof mount when the integral fixing member is the latter is the case of an active fluid-filled vibration-proof mount.

  According to the fluid-filled vibration isolating mount of the present invention, the first caulking member for caulking is made into two parts, that is, the first caulking member and the second caulking member, and the first caulking member and the second caulking member are Are integrated by bonding. Accordingly, the outer diameter of the first caulking member for caulking is the outer diameter of the outer diameter of the first caulking member plus the thickness of the second caulking member. On the other hand, in the conventional fluid-filled vibration-proof mount, the caulking integrated fixing member is formed by bending as described above. Therefore, the outer diameter of the first integral fixing member for caulking of the fluid-filled vibration-proof mount of the present invention is a portion extending toward the outer peripheral side of the caulking integrated fixing member of the conventional fluid-filled vibration-proof mount. Just make it smaller.

  Since the outer diameter of the caulking integrated fixing member constitutes the outermost diameter of the fluid-filled vibration isolating mount, the fluid-filled vibration isolating mount can be reduced by reducing the outer diameter of the caulking integral fixing member. This leads to a reduction in the outermost diameter.

  Further, the end face (support end face) of the first caulking member of the first integral fixing member forms a support portion that engages with the second integral fixing member for caulking. Therefore, the supporting end surface of the first caulking member can be reliably engaged with the second caulking integrated fixing member in the cylinder axis direction. Then, by bending (bending) the end of the second caulking member of the first integral fixing member, the second integral fixing member for caulking can be securely clamped by caulking. As a result, the plurality of integrally fixing members can be reliably fixed integrally.

  Furthermore, the outer diameter of the second integral fixing member may be an outer diameter that abuts on the support end surface of the first caulking member of the first integral fixing member. On the other hand, in the conventional fluid-filled vibration isolating mount, the outer diameter of the caulking integrated fixing member abuts on the portion extending outward in the radial direction by bending the caulking integrated fixing member. Must have an outer diameter. That is, according to the present invention, the outer diameter of the second integral fixing member can be reduced. As a result, it is possible to reduce the weight of the fluid-filled vibration proof mount.

  Furthermore, the first integral fixing member can be formed in advance by joining and forming the first and second caulking members formed into two parts. Other integral fixing members can be formed in advance in the same manner. And since these several integral fixing members are integrally fixed, manufacture can be performed easily.

  Further, the thickness of the first caulking member is preferably larger than the thickness of the second caulking member. As described above, the support end surface of the first caulking member is engaged with the second integral fixing member for caulking in the cylinder axis direction. Therefore, by enlarging the support end surface of the first caulking member, the second integral fixing member can be more reliably engaged in the cylinder axis direction. Furthermore, as described above, the outer diameter of the first integral fixing member is an outer diameter obtained by adding the thickness of the second caulking member to the outer diameter of the first caulking member. Therefore, by reducing the thickness of the second caulking member, it is possible to reduce the outer diameter of the first integral fixing member, and hence the outermost diameter of the fluid-filled vibration-proof mount. That is, by making the thickness of the first caulking member larger than the thickness of the second caulking member, the plurality of integrally fixing members can be more reliably integrally fixed, and the outermost of the fluid-filled vibration-proof mount The diameter can be reduced.

  Furthermore, since the thickness of the first caulking member is large, the area of the support end surface of the first caulking member is increased. Thereby, the 1st crimping member can support the 2nd integral fixing member for crimping reliably.

  The second integral fixing member has an outer peripheral plane portion extending in the cylinder axis orthogonal outer direction (radially outer side), and the support end surface of the first caulking member is the outer peripheral plane portion of the plurality of second integrated fixing members. And the second caulking member clamps the outer peripheral flat portions of the plurality of second integral fixing members in the cylinder axial direction between the second caulking member and the support end surface of the first caulking member. May be.

  That is, there are a plurality of second integral fixing members for caulking, and the portion of the outer peripheral flat surface portion of the second integral fixing member is clamped by the first integral fixing member. In the case where the second integrated fixing member has a shape having an outer peripheral flat surface portion, the plurality of integrated fixing members can be integrally fixed more firmly by adopting the caulking structure described above.

  The second integral fixing member includes an outer peripheral plane portion extending in the cylinder axis orthogonal outer direction (radially outer side) and a cylindrical member that is formed in a cylindrical shape and is joined to the outer peripheral side of the outer peripheral plane portion. The support end surface of the first caulking member is engaged with the cylindrical member in the cylinder axial direction, and the second caulking member is caulked with the cylindrical member between the support end surface of the first caulking member. You may make it pinch.

  That is, when the outermost peripheral end of the second integrated fixing member is bent, the second integrated fixing member is divided into two parts, that is, the outer peripheral plane portion and the cylindrical member. The cylindrical member is sandwiched between the first caulking member and the second caulking member of the first integral fixing member. Here, when the outermost peripheral end of the second integrated fixing member is bent, it may be formed by bending. However, when formed by bending, the bent forming portion of the second integral fixing member exists in the portion sandwiched between the first caulking member and the second caulking member of the first integral fixing member. As described above, when the bent forming portion is included in the portion sandwiched between the first caulking member and the second caulking member, the integral fixing of the integral fixing member may become unstable. On the other hand, as in the present invention, the bend forming portion is clamped between the first caulking member and the second caulking member by sandwiching the cylindrical member of the second integral fixing member between the first caulking member and the second caulking member. It is not included in the part clamped by the member. Therefore, the integral fixing of the plurality of integral fixing members is more stable.

  Further, the second caulking member has a caulking portion that caulks the second integral fixing member by bending and a jig end face that is abutted and supported by the pressing jig in a direction opposite to the cylindrical axis with respect to the caulking portion. It may be. That is, one end side of the second caulking member in the cylinder axis direction is used for caulking, and the other end side of the second caulking member in the cylinder axis direction abuts and supports the pressing jig used for caulking. Used for In this way, the pressing jig used for caulking can be contacted and supported by the second caulking member itself, so that the caulking portion can be bent and formed very stably.

  Moreover, the fluid-filled vibration isolating mount of the present invention may further include an elastic support member. This elastic support member is made of an elastic material, and is a member that is sandwiched between the plurality of second integrated fixing members together with the third integrated fixing member other than the second integrated fixing member among the other integrated fixing members. That is, the third integrated fixing member is sandwiched between the plurality of second integrated fixing members via the elastic support member. Here, if the number of the second integral fixing members clamped by the caulking is excessively increased by the first caulking member and the second caulking member of the first integral fixing member, There may be variations in dimensions. Therefore, the number of second integrated fixing members that the first integrated fixing member clamps by caulking may be limited. Therefore, by fixing the third integral fixing member so as to be sandwiched between the second integral fixing member via the elastic support portion, it is possible to prevent the variation in the size of the fluid-filled vibration isolating mount in the cylinder axis direction. it can.

  Here, in the above description, the present invention has been described for the fluid-filled vibration-proof mount, but the present invention can also be applied to a method for manufacturing a fluid-filled vibration-proof mount.

  That is, the method for manufacturing a fluid-filled vibration-proof mount of the present invention is a method for manufacturing a fluid-filled vibration-proof mount having a plurality of integral fixing members, and includes a jig arranging step, a second integral fixing member arranging step, And a caulking process. The jig arranging step is a step of arranging a holding jig. This pressing jig is a cylindrical shaft of a cylindrical second caulking member joined to the outer peripheral side of the cylindrical first caulking member among the first integrated fixing members which are any one of a plurality of integral fixing members. It is a jig for abutting and supporting one end surface of the first side. In the second integral fixing member arranging step, the second integral fixing member, which is at least one of the other integral fixing members, is engaged in the cylinder axis direction with respect to the support end surface of the first caulking member on the cylinder axis second side. It is the process of arranging so as to match. The caulking step is performed by bending the other end of the second caulking member of the first caulking member on the tube shaft second side inward and caulking the second integral fixing member between the supporting end surface of the first caulking member. This is a step of clamping in the cylinder axis direction.

  Here, the integral fixing member may be a plurality of members that are integrally fixed among the first mounting member, the elastic body supporting member, the pressure receiving chamber forming member, and the diaphragm supporting member, as described above. Alternatively, the integral fixing member may be a plurality of members that are integrally fixed among the first mounting member, the elastic body support member, the vibration plate support member, the actuator support member, and the diaphragm support member. That is, the fluid-filled vibration-proof mount in the case where the integral fixing member is the former includes the case of a so-called non-active fluid-filled vibration-proof mount and the case of a part of an active fluid-filled vibration-proof mount. become. Further, the fluid-filled vibration-proof mount when the integral fixing member is the latter is the case of an active fluid-filled vibration-proof mount.

  And according to the manufacturing method of the fluid filled type vibration-proof mount of the present invention, in a state where one end face (end face for jig) of the second caulking member of the first integral fixing member is in contact with and supported by the holding jig, The other end side (caulking part) of the second caulking member can be caulked (bent). Thereby, the caulking part of the second caulking member can be caulked very stably. Note that either the jig placement step or the second integrated fixing member placement step may be first.

  According to the fluid-filled vibration isolating mount of the present invention, a plurality of integrally fixing members can be securely fixed together, and the outermost diameter can be reduced. In addition, the weight can be reduced and the manufacturing can be facilitated. Moreover, according to the manufacturing method of the fluid filled type vibration-proof mount of this invention, the 2nd integral fixing member can be crimped very stably.

  Next, the present invention will be described in more detail with reference to embodiments.

  An engine mount for automobiles (hereinafter referred to as “engine mount”) will be described with reference to FIG. 1 as an embodiment of the fluid-filled vibration-proof mount of the present invention. FIG. 1 is a cross-sectional view of the engine mount of the present embodiment in the cylinder axis direction. The engine mount of this embodiment is a so-called active engine mount.

The first mounting bracket 1 includes a cylindrical portion 101, a mounting plate portion 102, and a flange portion 103. The cylindrical portion 101 is a portion having a substantially cylindrical shape, and is a portion that houses an electromagnetic actuator 12 and an actuator housing 11 described later. The mounting plate portion 102 is formed in a substantially hollow disk shape that extends radially outward from the lower end opening of the tube portion 101. The mounting plate portion 102 is formed with a plurality of mounting holes (not shown) through which bolts for fixing to the vehicle body are inserted. The flange portion 103 is formed in a substantially hollow disk shape extending from the upper end opening of the tube portion 101 to the outside in the radial direction (the direction perpendicular to the tube axis). Here, the 1st attachment metal fitting 1 comprises the caulking member caulked by the diaphragm outer metal fitting 5 which is the caulking member mentioned later. The outer peripheral end of the flange portion 103 is a portion that is caulked by the diaphragm outer metal fitting 5.

  The main rubber inner fitting 201 has a substantially truncated cone shape in the reverse direction. On the upper surface of the main rubber inner metal fitting 201, a circular fitting recess 201a is formed on the lower side. Furthermore, a screw hole 201b is formed in the bottom surface of the fitting recess 201a of the main rubber inner fitting 201 and screwed into the connecting bolt 203.

  The diaphragm inner metal fitting 202 has a thick disk shape. On the lower surface of the diaphragm inner metal fitting 202, there is a circular fitting convex portion 202a protruding downward. The fitting convex portion 202a is fitted into a fitting concave portion 201a formed in the main rubber inner metal fitting 201. Further, the diaphragm inner metal fitting 202 includes a fitting convex portion 202a, penetrates in the cylinder axis direction, and has a connection bolt insertion hole 202b through which the connection bolt 203 is inserted. Further, a mounting plate 202c that protrudes upward and is attached to the power unit is integrally formed above the diaphragm inner metal fitting 202. A bolt insertion hole 202d for inserting a bolt for connecting the power unit is formed in the central portion of the mounting plate 202c.

  That is, the diaphragm inner metal fitting 202 is directly superimposed on the upper surface of the main rubber inner metal fitting 201, and the fitting convex portion 202a of the diaphragm inner metal fitting 202 is fitted into the fitting concave portion 201a of the main rubber inner metal fitting 201. Thus, the main rubber inner metal fitting 201 and the diaphragm inner metal fitting 202 are coaxially aligned by fitting the fitting concave portion 201a and the fitting convex portion 202a. As a result, the screw hole 201b formed in the main rubber inner fitting 201 and the bolt insertion hole 202d formed in the diaphragm inner fitting 202 are further aligned. In addition, engaging portions (not shown) that engage with each other are formed on the outer peripheral surfaces of the fitting recess 201a and the fitting projection 202a, respectively. The main rubber inner metal fitting 201 and the diaphragm inner metal fitting 202 are positioned in the circumferential direction by the engagement of the engaging portions.

The outer peripheral end of the flange portion 302 of the main rubber outer metal fitting 3 is a portion caulked by the diaphragm outer metal fitting 5.

  The main rubber elastic body 4 has a large-diameter truncated cone shape as a whole. A main rubber inner metal fitting 201 is coaxially disposed and vulcanized and bonded to the upper central portion of the main rubber elastic body 4. Thus, the main rubber elastic body 4 is supported on the main rubber inner metal fitting 210. Further, a taper portion 303 of the main rubber outer metal fitting 3 is vulcanized and bonded to the lower large-diameter end of the main rubber elastic body 4.

That is, the main rubber elastic body 4 elastically connects the main rubber inner metal fitting 201 and the main rubber outer metal fitting 3. The main rubber elastic body 4, the main rubber inner metal fitting 201, and the main rubber outer metal fitting 3 form an integrally vulcanized molded product. A circumferential groove extending in the circumferential direction with a length of a little less than one round is formed on the outer peripheral side of the main rubber outer metal fitting 3.

  The diaphragm outer metal fitting 5 (diaphragm support member, first integrated fixing member in the present invention) has a cylindrical shape, and is arranged coaxially with the main rubber outer metal fitting 3 and on the outer peripheral side of the main rubber outer metal fitting 3. The diaphragm outer metal fitting 5 will be described with reference to FIG. 2 in addition to FIG. 2A is an enlarged view of a portion A in FIG. 1, and FIG. 2B is a partial development view of the second caulking member of the diaphragm outer metal fitting 5 as viewed from the right side in FIG. 2A. .

  As shown in FIGS. 1 and 2, the diaphragm outer metal fitting 5 includes a first caulking member 501 and a second caulking member 502. The diaphragm outer metal fitting 5 constitutes a caulking member. That is, the diaphragm outer metal fitting 5 is a member for caulking the first mounting metal fitting 1, the main body rubber outer metal fitting 3, and the vibration plate holding metal fitting 7 that are caulked members.

  The first caulking member 501 includes a cylindrical portion 501a and a flange portion 501b. The cylindrical portion 501a of the first caulking member 501 is a substantially cylindrical portion, and has an inner diameter larger than the outer diameter of the cylindrical portion 301 of the main rubber outer metal fitting 3. The cylindrical portion 501 a of the first caulking member 501 is disposed on the outer peripheral side of the cylindrical portion 301 and the tapered portion 303 of the main rubber outer metal fitting 3. The lower end surface (support end surface in the present invention) of the cylindrical portion 501a of the first caulking member 501 is the outer peripheral plane portion of the flange portion 103 of the first mounting bracket 1 and the outer peripheral plane portion of the flange portion 302 of the main rubber outer bracket 3. And the outer peripheral end of the upper flange part 702 (described later) of the vibration plate holding metal fitting 7 is engaged in the cylinder axis direction. The lower end surface of the cylindrical portion 501 a of the first caulking member 501 is in contact with the upper surface of the flange portion 302 of the main rubber outer metal fitting 3.

  Further, a seal rubber integrally formed with a diaphragm 6 to be described later is interposed between the inner peripheral side of the cylindrical portion 501a of the first caulking member 501 and the flange portion 302 of the main rubber outer metal fitting 3, thereby sealing the fluid tightly. Has been. Similarly, a seal rubber integrally formed with the diaphragm 6 is interposed between the inner peripheral side of the cylindrical portion 501a of the first caulking member 501 and the taper portion 303 of the main rubber outer metal fitting 3, thereby sealing the fluid tightly. Has been. Therefore, an annular passage (orifice passage in the present invention) 14 is formed between the main rubber outer metal fitting 3 and the first caulking member 501 so as to continuously extend over a predetermined length or the entire circumference in the circumferential direction.

  The flange portion 501b of the first caulking member 501 is formed in a substantially hollow disk shape that extends radially outward from the upper end opening of the cylindrical portion 501a. A bolt mounting hole (not shown) for mounting a bolt for preventing detachment is formed in the flange portion 501b.

  The second caulking member 502 has a cylindrical shape and is welded to the outer peripheral side of the first caulking member 501. The second caulking member 502 includes a cylindrical portion 502a and a caulking portion 502b. The cylindrical portion 502a has a cylindrical shape. The plate thickness (wall thickness) of the tube portion 502a is smaller than the plate thickness (wall thickness) of the tube portion 501a of the first caulking member 501. The inner diameter of the cylindrical portion 502 a of the second caulking member 502 is substantially the same as the outer diameter of the cylindrical portion 501 a of the first caulking member 501. Further, as shown in FIG. 2B, the cylindrical portion 502a has a plurality of concave portions 502c formed on the upper side. And the bottom face of the recessed part 502c of the cylinder part 502a and the outer peripheral surface of the cylinder part 501a of the 1st crimping member 501 are weld-joined. Further, the upper end surface of the cylindrical portion 502a (the end surface for the jig in the present invention, the one end surface on the first side of the cylindrical shaft) is a portion that abuts and supports the pressing jig 17 used for caulking. The caulking portion 502b (the other end on the second side of the cylinder shaft in the present invention) is bent and formed in a substantially hollow disk shape so as to extend radially inward from the lower end opening of the cylinder portion 502a. The caulking portion 502a sandwiches the caulking member by caulking between the lower end surface of the cylindrical portion 501a of the first caulking member 501.

  The diaphragm 6 is formed of a thin rubber film and has a shape that can easily be elastically deformed. The upper inner peripheral side of the diaphragm 6 is vulcanized and bonded to the outer peripheral side of the diaphragm inner fitting 202. In this way, the diaphragm 6 is supported by the diaphragm inner metal fitting 202. Further, the lower outer peripheral side of the diaphragm 6 is vulcanized and bonded to the inner peripheral side of the cylindrical portion 501 a of the first caulking member 501 of the diaphragm outer metal fitting 5. Thus, the diaphragm 6 is supported by the first caulking member 501 of the diaphragm outer metal fitting 5. That is, the diaphragm 6 connects the diaphragm inner metal fitting 202 and the diaphragm outer metal fitting 5. The diaphragm 6, the diaphragm inner metal fitting 202, and the diaphragm outer metal fitting 5 form an integrally vulcanized molded product.

  An equilibrium chamber 15 in which an incompressible fluid is sealed is formed between the diaphragm 6 and the upper surface side of the main rubber elastic body 4. Since the equilibrium chamber 15 is formed by the easily deformable diaphragm 6, the volume change is easily allowed based on the elastic deformation of the diaphragm 6. The equilibrium chamber 15 communicates with the annular passage 14 formed by the main rubber outer metal fitting 3 and the first caulking member 501.

  The vibration plate holding metal fitting 7 (the pressure receiving chamber forming member, the vibration plate supporting member, and the second integral fixing member in the present invention) has a substantially annular shape, and is disposed below the main rubber outer metal fitting 3. The vibration plate holding metal fitting 7 includes a cylindrical portion 701, an upper flange portion 702, and a lower flange portion 703. The cylindrical portion 701 has a cylindrical shape and has an inner diameter larger than the outer diameter of the upper end portion 122a of the plunger 122 of the electromagnetic actuator 12 described later. The upper flange portion 702 is formed in a substantially hollow disk shape that extends radially outward from the upper end opening of the cylindrical portion 701. The outer peripheral end of the upper flange portion 702 is slightly bent at the lower side. The outer flange end of the upper flange portion 702 is engaged with the lower end surface of the cylinder portion 501a of the first caulking member 501 in the cylinder axis direction. That is, the outer diameter of the bent portion of the upper flange portion 702 is larger than the inner diameter of the cylindrical portion 501 a of the first caulking member 501 and smaller than the inner diameter of the cylindrical portion 502 a of the second caulking member 502. Furthermore, the upper surface of the upper flange portion 702 is in contact with the lower surface of the flange portion 302 of the main rubber outer metal fitting 3. Further, the lower end surface of the bent portion of the upper flange portion 702 is in contact with the upper surface of the flange portion 103 of the first mounting bracket 1. The lower flange portion 703 is formed in a substantially hollow disk shape that extends radially outward from the lower end opening of the cylindrical portion 701. An outer peripheral surface of the lower flange portion 702 is in contact with an inner peripheral surface of an actuator housing 11 described later.

And the vibration plate 8, the vibration plate holding | maintenance metal fitting 7, and the plunger 122 form the integral vulcanization molded product. A pressure receiving chamber 16 in which an incompressible fluid is sealed is formed between the vibration plate 8 and the vibration plate holding metal fitting 7 and the lower surface side of the main rubber elastic body 4. The pressure receiving chamber 16 generates a pressure fluctuation based on the vibration of the main rubber elastic body 4. Furthermore, the pressure receiving chamber 16 also varies in pressure due to the displacement of the vibration plate 8. The pressure receiving chamber 16 communicates with the annular passage 14 formed by the main rubber outer metal fitting 3 and the first caulking member 501. That is, the pressure receiving chamber 16 communicates with the equilibrium chamber 15 through the annular passage 14.

  The partition plate fitting 9 (the third integrated fixing member in the present invention) has a thin disk shape. The outer diameter of the partition plate fitting 9 is made smaller than the outer diameter of the upper flange portion 702 of the vibration plate holding fitting 7. Furthermore, the outer diameter of the partition plate metal 9 is made larger than the inner diameter of the cylindrical portion 301 of the main rubber outer metal fitting 3.

It is pinched and fixed between. Moreover, the center part of the partition plate metal fitting 9 protrudes upward in a substantially plateau shape. An orifice hole 901 is formed on the central axis of the central portion.

  Here, the partition plate fitting 9 divides the pressure receiving chamber 16 into two. Specifically, the pressure receiving chamber 16 is divided into a main liquid chamber 161 formed by the partition plate fitting 9 and the main rubber elastic body 4, and a sub liquid chamber 162 formed by the partition plate fitting 9 and the vibration plate 8. It is divided into. The main liquid chamber 161 and the sub liquid chamber 162 communicate with each other through an orifice hole 901. The main liquid chamber 161 is a region in which pressure fluctuation occurs mainly based on the vibration of the main rubber elastic body 4. On the other hand, the secondary liquid chamber 162 is a region where pressure fluctuation occurs mainly based on the displacement of the vibration plate 8.

  The actuator housing 11 (actuator support member, third integrated fixing member in the present invention) has a substantially cylindrical shape and is arranged on the inner peripheral side of the first mounting bracket 1 coaxially with the first mounting bracket 1. Further, the actuator housing 11 houses and supports the electromagnetic actuator 12 therein. The actuator housing 11 includes a cylindrical part 111, a flange part 112, and an actuator holding part 113. The cylindrical portion 111 is a substantially cylindrical portion, and is arranged coaxially so as to face the inner peripheral surface of the cylindrical portion 101 of the first mounting bracket 1. The flange portion 112 is formed in a substantially hollow disk shape that extends radially outward from the upper end opening of the cylindrical portion 111. The flange portion 112 is disposed between the upper flange portion 702 of the vibration plate holding bracket 7 and the flange portion 101 of the first mounting bracket 1. Furthermore, the outer diameter of the flange portion 112 of the actuator housing 11 is made smaller than the inner diameter of the bent portion of the upper flange portion 702 of the vibration plate holding bracket 7. The actuator holding portion 113 of the actuator housing 11 is formed in a substantially hollow disk shape that extends radially inward from the lower end opening of the cylindrical portion 111. The upper surface side of the actuator holding portion 113 supports the lower end side of the electromagnetic actuator 12.

  The fitting rubber 13 (the elastic support member in the present invention) is disposed in a portion surrounded by the cylindrical portion 701, the upper flange portion 702, and the lower flange portion 703 of the vibration plate holding metal fitting 7. The fitting rubber 13 is vulcanized and bonded to the outer peripheral side of the vibration plate holding metal fitting 7 and the actuator housing 11. More specifically, the fitting rubber 13 is vulcanized and bonded to the lower surface of the upper flange portion 702 of the vibration plate holding bracket 7 and the upper surface of the flange portion 112 of the actuator housing 11. That is, the flange portion 112 of the actuator housing 11 is sandwiched and fixed between the upper flange portion 702 of the vibration plate holding bracket 7 and the flange portion 103 of the first mounting bracket 1 together with a part of the fitting rubber 13. .

  The electromagnetic actuator 12 includes a core 121 and a plunger 122. The core 121 has a substantially cylindrical shape, and is housed and fixed inside the actuator housing 11. The core 121 includes a coil member 121a around which a coil is wound, and yokes 121b and 121c that form a magnetic path disposed on the outer periphery of the coil member 121a.

  The plunger 122 is made of a ferromagnetic material and has a substantially axial shape. The plunger 122 is arranged in the center hole of the core 121 so as to be movable in the cylinder axis direction. The upper end 122a of the plunger 122 is vulcanized and bonded to the center of the vibration plate 8 described above. That is, the plunger 122 is integrated with the vibration plate 8. The plunger 122 is attracted downward by the magnetic force generated by energizing the coil member 121 a of the core 121. That is, by energizing the coil member 121a of the core 121, the vicinity of the center of the vibration plate 8 is displaced downward by the plunger 122. More specifically, the displacement of the vibration plate 8 can be changed as appropriate according to the amount of current supplied to the coil member 121a.

(3) Caulking method Next, the first mounting bracket 1, the main rubber outer bracket 3, the diaphragm outer bracket 5, the vibration plate holding bracket 7, the partition plate bracket 9, and the actuator housing 11 are integrally fixed. Will be described with reference to FIG. FIG. 2A is an enlarged view of a portion A in FIG.

  First, before these are integrally fixed, the caulking portion 502b of the second caulking member 502 of the diaphragm outer metal fitting 5 is not bent. That is, the second caulking member 502 has a cylindrical shape due to the cylindrical portion 502a and the caulking portion 502b.

  Then, in the liquid of the incompressible fluid, the integral vulcanization molded product including the main rubber outer metal fitting 3 is disposed inside the integral vulcanization molded product including the diaphragm outer metal fitting 5 in such a state as shown in FIG. Inserting from below (second integrated fixing member arranging step). Specifically, the fitting convex part 202a of the diaphragm inner metal fitting 202 and the fitting concave part 201a of the main rubber inner metal fitting 201 are fitted. Further, the flange portion 302 of the main rubber outer metal fitting 3 is inserted inside the second caulking member 502. Then, the upper surface on the outer peripheral side of the flange portion 302 of the main rubber outer metal fitting 3 is brought into contact with the lower end surface of the first caulking member 501 of the diaphragm outer metal fitting 5. At this time, the incompressible fluid is sealed in the equilibrium chamber 15.

  Subsequently, in the liquid of the incompressible fluid, the integrally vulcanized molded product including the partition plate metal fitting 9 and the vibration plate 8 is changed to the lower side of the integral vulcanized molded product including the main rubber outer metal fitting 3 in FIG. (Second integrated fixing member arranging step). Specifically, the upper flange portion 702 of the vibration plate holding metal fitting 7 is inserted inside the second caulking member 502. Then, the upper surface of the upper flange portion 702 of the vibration plate holding metal fitting 7 is brought into contact with the lower surface of the flange portion 302 of the main rubber outer metal fitting 3. At this time, the incompressible fluid is sealed in the pressure receiving chamber 16.

  Subsequently, outside the liquid, the actuator housing 11 fixed integrally with the core 121 of the electromagnetic actuator 12 is disposed on the lower side of the vibration plate holding metal fitting 7 in FIG. Specifically, the flange portion 112 of the actuator housing 11 is inserted into the second caulking member 502 from the lower side in FIG. Then, the upper surface on the outer peripheral side of the flange portion 112 of the actuator housing 11 is brought into contact with the lower end surface of the bent portion of the upper flange portion 702 of the vibration plate holding bracket 7.

  Subsequently, outside the liquid, the first mounting bracket 1 is arranged on the outer peripheral side of the actuator housing 11 (second integrated fixing member arranging step). Specifically, the flange portion 103 of the first mounting bracket 1 is inserted into the second caulking member 502 from the lower side in FIG. Then, the upper surface on the outer peripheral side of the flange portion 103 of the first mounting bracket 1 is brought into contact with the lower surface of the flange portion 112 of the actuator housing 11.

  Subsequently, the upper end surface of the second caulking member 502 is brought into contact with and supported by the pressing jig 17 (jig arranging step). Subsequently, in a state where the upper end surface of the second caulking member 502 is in contact with and supported by the holding jig 17, the lower side (the caulking portion 502b portion) of the second caulking member 502 in FIG. (Caulking process). In this manner, the main rubber outer metal fitting 3, the vibration plate holding metal fitting 7, and the first attachment metal fitting 1 are connected between the caulking portion 502 b of the second caulking member 502 and the lower end surface of the first caulking member 501. Hold by caulking. That is, the diaphragm outer metal fitting 5, the main rubber outer metal fitting 3, the vibration plate holding metal fitting 7, and the first mounting metal fitting 1 are integrally fixed by caulking.

  Further, the partition plate metal 9 is clamped and fixed between the upper flange portion 702 of the vibration plate holding metal fitting 7 and the flange portion 302 of the main body rubber outer metal fitting 3 together with a part of the main rubber elastic body 4 in accordance with the caulking. Has been. In this way, the partition plate fitting 9 is integrally fixed to the vibration plate holding fitting 7 and the main rubber outer fitting 3.

  In addition, the flange portion 112 of the actuator housing 11 is sandwiched and fixed between the upper flange portion 702 of the vibration plate holding bracket 7 and the flange portion 103 of the first mounting bracket 1 together with a part of the fitting rubber 13. . In this way, the actuator housing 11 is integrally fixed to the vibration plate holding bracket 7 and the first mounting bracket 1.

(4) Operation of Engine Mount Next, the operation of the engine mount having the above-described configuration will be described. The first mounting bracket 1 is mounted on the vehicle body of the automobile, and the second mounting bracket 2 is mounted on the power unit. In this case, since the power unit moves relative to the vehicle body, vibration is generated between the first mounting bracket 1 and the second mounting bracket 2. When vibration is generated between the first mounting bracket 1 and the second mounting bracket 2, the main rubber elastic body 4 is elastically deformed. As the main rubber elastic body 4 is elastically deformed, the pressure receiving chamber 16 changes in pressure. Then, a pressure difference is generated between the pressure receiving chamber 16 and the equilibrium chamber 15, and fluid flow occurs through the annular passage 14. Based on the fluid action such as the resonance action of the fluid, the effect of passively isolating the power unit with respect to the vehicle body is exhibited. Here, the cross-sectional area and the passage length of the annular passage 14 are appropriately adjusted so that the passive vibration-proofing effect is effectively exhibited in a specific frequency region such as idling vibration.

  Furthermore, the vibration plate 8 is vibrated and vibrated by the plunger 122 by energizing the coil member 121 a of the core 121 of the electromagnetic actuator 12. As a result, pressure fluctuation is exerted on the main liquid chamber 161 from the sub liquid chamber 162 through the orifice hole 901. As a result, active vibration isolation effects can be achieved by actively suppressing pressure fluctuations in the main liquid chamber 161. Here, it is possible to suppress appropriate vibrations by adjusting the energization amount to the coil member 121a based on the frequency and phase corresponding to the vibration to be shaken.

(5) Effect As described above, the outer diameter of the engine mount can be reduced by configuring the diaphragm outer metal fitting 5 by the first caulking member 501 and the second caulking member 502. Furthermore, since the presser jig 17 is caulked by the caulking portion 502 in a state where the presser jig 17 is in contact with and supported by the upper end surface of the second caulking member 502, the caulking member can be caulked very stably.

  Further, according to the configuration of the engine mount as described above, the flange portion 302 of the main rubber outer bracket 3, the vibration plate holding bracket 7, the flange portion 103 of the first mounting bracket 1, the flange portion 112 of the actuator housing 11, and the partition Each of the metal plates 9 has a flat surface portion (an outer peripheral flat surface portion in the present invention) extending outward in the radial direction. In the case where there are a plurality of such flat portions, the outer diameter of only a specific position is enlarged when clamping and fixing by caulking. Therefore, when there are a plurality of flat portions, the problem that the outer diameter of only a specific position is enlarged can be effectively reduced by adopting the above-described caulking structure.

  Further, the thickness of the cylindrical portion 501 a of the first caulking member 501 is made larger than the thickness of the cylindrical portion 502 a of the second caulking member 502. Thereby, the outer diameter of an engine mount can be made small. Furthermore, the caulking member can be reliably supported by increasing the thickness of the cylindrical portion 501a of the first caulking member 501.

(6) Other embodiment In the said embodiment, although the 1st crimping member 501 of the diaphragm outer metal fitting 5 is vulcanized-bonded to the diaphragm 6, it is not restricted to this. For example, as shown in FIG. 3, the upper end side of the second caulking member 502 located on the outer peripheral side may be formed above the upper end side of the first caulking member 501 located on the inner peripheral side. . In this case, the second caulking member 502 is mainly vulcanized and bonded to the diaphragm 6 to support the diaphragm 6. Also in this case, the engine mount can be reduced in size as described above. However, it is necessary to secure a place where the pressing jig 17 is contacted and supported. In FIG. 3, the first caulking member 501 and the second caulking member 502 are both vulcanized and bonded to the diaphragm 6.

  Moreover, in the said embodiment, although the upper flange part 702 of the vibration plate holding | maintenance metal fitting 7 formed the outer periphery end bend | folded, it is not restricted to this. For example, as shown in FIG. 4, the upper flange portion 702 of the vibration plate holding bracket 7 may be made into two parts. Specifically, the upper flange portion 702 is configured by a flat portion 702a (the outer peripheral flat portion in the present invention) and an outer peripheral cylindrical portion 702b (the cylindrical member in the present invention). The flat surface portion 702a is formed in a substantially hollow disk shape so as to extend radially outward from the upper end opening of the cylindrical portion 701 of the vibration plate holding metal fitting 7. The outer peripheral cylindrical portion 702b has a cylindrical shape and is welded to the outer peripheral side of the flat surface portion 702a. The outer peripheral cylindrical portion 702b has substantially the same diameter as the cylindrical portion 501a of the first caulking member 501.

  That is, when the vibration plate holding metal fitting 7 having the above-described configuration is caulked by the diaphragm outer metal fitting 5, the outer peripheral cylindrical portion 702 b of the upper flange portion 702 of the vibration plate holding metal fitting 7 is the cylindrical portion of the first caulking member 501. It is sandwiched between the lower end surface of 501a and the caulking portion 502b of the second caulking member 502.

  In this manner, the outer cylindrical portion 702b is sandwiched between the first caulking member 501 and the second caulking member 502, so that the bending formation portion existing in the upper flange portion 702 of the above embodiment is the first caulking member 501. It is not included in the portion clamped by the second caulking member 502. That is, the integral fixing by caulking is very stable.

  Moreover, the engine mount of the said embodiment was demonstrated as what is called an active engine mount provided with the electromagnetic actuator 12. FIG. However, the present invention can also be applied to a non-active engine mount. The configuration of the engine mount in this case is a configuration excluding the portion related to the electromagnetic actuator 12, and the configuration related to the vibration plate 8 and the partition plate metal piece 9 simply forms the pressure receiving chamber 16 where the vibration does not change. Become. And as a caulking member, it is set as the main body rubber outer metal fitting 3, the pressure receiving chamber formation member equivalent to the vibration board 8, the 1st attachment metal fitting 1, etc., for example.

  Moreover, in the said embodiment, the diaphragm outer metal fitting 5 is applied as a caulking member, and the main body rubber outer metal fitting 3, the vibration plate holding metal fitting 7, and the first mounting metal fitting 1 are applied as caulking members, and rubber ( As a member to be integrally fixed via the main rubber elastic body 4 or the fitting rubber 13), the partition plate metal fitting 9 and the actuator housing 11 were applied.
