Description

  The present invention relates to a suspension support for elastically coupling a piston rod of a shock absorber in a suspension mechanism of a vehicle such as an automobile to a vehicle body.

  2. Description of the Related Art Conventionally, in an automobile suspension mechanism, an inner member into which an upper end portion of a piston rod of a shock absorber is inserted and fixed in order to suppress transmission of vibration from a wheel side to a vehicle body side, surrounds the outer periphery of the inner member. A suspension support including an outer member attached to the side and an annular elastic member interposed between the inner member and the outer member is used. Then, as disclosed in Patent Documents 1 and 2 below, the inner member is provided with a flange portion projecting outward in the direction perpendicular to the axis, and has an U-shaped cross-sectional shape so as to wrap the flange portion. There is one in which a member is provided and the outer member is provided in a container shape so as to accommodate the elastic member.

  In such a suspension support, conventionally, the elastic member is generally formed of a rubber material, and is configured by vulcanizing a rubber elastic body around the flange portion of the inner member. On the other hand, foamed resin materials such as foamed urethane have higher damping properties than rubber materials, and therefore, when used for suspension support, ride comfort can be improved. For this reason, development of a suspension support using an elastic member made of foamed resin has been promoted (see Patent Document 3 below).

  In the suspension support having the above-described configuration, when the elastic member is formed of foamed resin, an integrally molded body is obtained by adopting a method of integrally molding the foamed resin elastic member so as to wrap the flange portion of the inner member. For this reason, a dedicated facility is required, which increases the manufacturing cost. On the other hand, when only the elastic member is molded separately from the inner member, since the entire elastic member has a U-shaped cross section, there is a problem that the undercut amount increases and the moldability is impaired. Further, as proposed in Patent Document 3, the elastic member is formed into a straight cylindrical shape, and when assembled to the outer member, both axial end portions are bent radially inward to form a U-shaped cross section. In such a measure, stress due to compression acts on the inner peripheral side of the bent portion, whereas stress due to tension acts on the outer peripheral side of the bent portion, and there is a concern that these undesired force distributions may cause destruction. Is done.

  Further, in the suspension support having the U-shaped elastic member that wraps around the flange portion of the inner member in this way, both the upper and lower ends of the outer peripheral edge portion of the flange portion with respect to the input in which the inner member is displaced in the vertical direction The corners of the elastic member located in the vicinity of the part are likely to be the starting point of destruction, and the durability may be impaired.

  Patent Documents 4 and 5 below disclose that a stopper cushion is provided on each of the upper surface and the lower surface of the inner member of the suspension support, and the stopper cushion is molded with urethane foam. However, the suspension supports of these documents include an elastic body made of a rubber material as an elastic member that supports the inner member against the outer member in a vibration-proof manner. Therefore, the stopper cushion is provided by the outer member. It is not held in the axial direction and does not correspond to an elastic member that joins the inner member and the outer member.

Further, in Patent Document 6 below, an inner member fixed to the upper end portion of the piston rod includes upper and lower flange portions, and an outer member is disposed between the upper and lower flange portions. A foamed resin material such as urethane foam is interposed in a stopper portion between the flange portion of the inner member and the upper and lower end portions of the outer member facing the inner peripheral surface of the inner member. Technology is disclosed. However, even in this document, the foamed resin material does not correspond to an elastic member for supporting the inner member with respect to the outer member in a vibration-proof manner. Therefore, a foamed resin material is provided and does not disclose any features of the present invention described later.
JP 2001-347814 A JP 2006-151124 A JP 2003-184937 A Japanese Patent No. 3770432 Japanese Patent Laid-Open No. 2001-065626 JP 2004-353718 A

  The present invention has been made in view of the above points, and an object of the present invention is to provide a suspension support using an elastic member made of foamed resin, which can improve durability and productivity.

The suspension support according to the present invention includes an inner member into which an upper end portion of a piston rod of a shock absorber is inserted and fixed, an outer member that surrounds an outer periphery of the inner member and is attached to a vehicle body side, and between the inner member and the outer member. An annular elastic member formed of a foamed resin molded body interposed between the inner member, the inner member includes a flange portion projecting outward in the direction perpendicular to the axis of the piston rod, and the outer member includes the elastic member. A cylindrical portion that includes the upper side wall portion and the lower side wall portion that are formed inwardly in a direction perpendicular to the axial direction at both axial end portions of the cylindrical portion and sandwich the elastic member in the axial direction. The member is clamped and held between the upper elastic portion held between the upper surface of the flange portion and the lower surface of the upper side wall portion, and between the lower surface of the flange portion and the upper surface of the lower side wall portion. under An elastic portion, the annular connecting the upper resilient portion and lower resilient portion interposed in contact on the outer peripheral surface and the inner circumferential surface between the outer peripheral surface and the inner peripheral surface of the cylindrical portion of the flange portion A vertical wall portion, the upper elastic portion and the lower elastic portion are separately molded, and are integrally assembled between the inner member and the outer member, and at least a part of the vertical wall portion is the A concave portion extending in the circumferential direction at a corner portion on the inner peripheral side of the base portion of the integrally formed vertical wall portion with respect to the elastic portion is integrally formed with at least one elastic portion of the upper elastic portion and the lower elastic portion. The concave portion is formed by being depressed in the axial direction at a position facing the upper surface or the lower surface of the outer peripheral edge of the flange portion .

  According to the above configuration, the elastic member made of the foamed resin molded body is divided into upper and lower parts, and is molded between the inner member and the outer member after the forming to be an integrated product, so that it becomes an undercut shape at the time of molding. The moldability can be improved. Moreover, since it does not forcibly bend at the time of assembly | attachment like the said patent document 3, undesired force distribution can be reduced and durability can be improved.

Moreover, since the recessed part extended in the circumferential direction was provided in the inner peripheral side corner part of the base part of the said elastic part and a vertical wall part, the following effect is show | played. That is, the inner peripheral side corner is located in the vicinity of the upper and lower corners of the flange portion of the inner member, and this portion tends to become a starting point of destruction due to concentration of force when the inner member is displaced in the vertical direction. Therefore, by providing the concave portion in this portion as described above, concentration of force can be reduced and durability can be improved. Since the recess is provided inside the U-shape of the elastic member, it can be formed because the elastic member is divided as described above, and this point is also an advantage of the divided type. In addition, the said recessed part should just be provided in the state before the assembly of a suspension support, and may be a recessed part of the grade collapsed completely in the assembled state. Even in the recessed portion that is crushed in the assembled state, the force distribution inside the elastic member is improved as compared with the case without the recessed portion, and it can be avoided that it becomes the starting point of destruction.
In addition, since the concave portion is provided to be depressed in the axial direction at a position facing the upper surface or the lower surface of the outer peripheral edge portion of the flange portion, the upper and lower end portions of the flange portion with respect to a twisting displacement in which the piston rod is inclined. It is possible to effectively reduce the concentration of force in the case and has excellent durability.

  In the present invention, since the elastic member is a vertically divided type as described above, the upper elastic portion and the lower elastic portion can be formed of foamed resin molded bodies having different hardnesses. This makes it possible to make a difference in the rigidity of the suspension support, that is, the spring characteristics, when the inner member is displaced upward relative to the outer member. The vertical spring can be set accordingly. Measures for changing the hardness include changing the density of the foamed resin molded body or changing the type of the foamed resin.

  When the upper and lower elastic parts have different hardnesses, the upper elastic part can be made harder than the lower elastic part, but the upper elastic part should be formed of a foamed resin molded body having a lower hardness than the lower elastic part. Is preferred. As a result, it is possible to improve the ride comfort by receiving softly against the upward push of the wheel, and to improve the effect of restricting the downward displacement of the wheel, between the links on the lower side of the shock absorber. Can prevent interference.

  In the present invention, the vertical wall portion protrudes integrally from the lower surface of the upper elastic portion downward and integrally projects upward from the upper surface of the lower elastic portion. The lower vertical wall portion that is made to abut on the outer periphery of the flange portion, and the concave portion is a corner on the inner peripheral side of the base portion of the upper vertical wall portion with respect to the upper elastic portion, and When the lower vertical wall portion is formed on the inner peripheral side corner portion of the base portion with respect to the lower elastic portion, the following effects are obtained.

  That is, by providing the upper vertical wall portion and the lower vertical wall portion, the upper elastic portion and the lower elastic portion are each formed with a concave portion that receives the flange portion of the inner member. In the process, the upper elastic part and the lower elastic part can be temporarily assembled on both the upper and lower sides of the inner member by the flange holding effect by the concave part, and the assembly workability is excellent. Further, by providing the concave portion at the base portion of the vertical wall portion in each of the upper and lower elastic portions, it is possible to reduce the concentration of force at the upper and lower end portions of the flange portion and improve the durability. Further, when the upper elastic portion and the lower elastic portion have different hardnesses, the rigidity of the suspension support in the direction perpendicular to the axis is appropriately changed by changing the height ratio between the upper vertical wall portion and the lower vertical wall portion. be able to.

  Further, in the present invention, the vertical wall portion includes a plurality of upper convex portions projecting downward from a plurality of circumferential locations on the lower surface of the upper elastic portion, and a plurality of circumferential projections on the upper surface of the lower elastic portion. It may be configured by alternately fitting a plurality of lower convex portions projecting upward from the places in the circumferential direction. In this way, the vertical wall portion is configured by meshing convex portions protruding alternately from the upper and lower elastic portions, so that in the suspension support assembly process, the upper elastic portion and the lower elastic portion are temporarily assembled on the upper and lower sides of the inner member. In this state, it is possible to prevent the elastic portions from coming off, and the assembly workability is excellent.

  Examples of the elastic member include a foamed urethane (polyurethane) molded body and a foamed ethylene vinyl acrylate molded body, and a foamed urethane molded body is particularly preferably used from the viewpoint of durability.

  With the suspension support of the present invention, productivity and durability can be improved in a suspension support using an elastic member made of a foamed resin molded body that exhibits excellent ride comfort due to high damping properties.

(First embodiment)
FIG. 1 is an exploded sectional view of a suspension support 10 according to the first embodiment, FIG. 2 is a sectional view in the assembling process, and FIG. 3 is a sectional view in an assembled state.

An annular elastic member 16 is provided between the inner metal fitting 12 and the outer metal fitting 14 to support the inner metal fitting 12 with respect to the outer metal fitting 14 in a vibration-proof manner. The suspension support 10 is provided with the axial direction X of the piston rod 1 as the vertical direction.

  The inner metal fitting 12 includes a cylindrical inner cylinder portion 18 into which the upper end portion 1A of the piston rod 1 is inserted from below, and a ring plate projecting from the upper end portion of the inner cylinder portion 18 to the outer side Y1 in the direction perpendicular to the axis of the piston rod 1. And a flange portion 20 having a shape. The flange portion 20 is thicker than the thickness of the inner cylinder portion 18, and a counterbore portion 22 for the nut 3 for fastening and fixing the piston rod upper end portion 1A is concave in the central portion of the upper surface 20A. Is provided.

  The outer metal fitting 14 is formed in a cylindrical portion 24 containing the elastic member 16 and inward Y2 in the direction perpendicular to the axis Y at both ends in the axial direction X of the cylindrical portion 24, and sandwiches the elastic member 16 in the axial direction X. The upper side wall part 26 and the lower side wall part 28 to be pressed are provided, and is formed in a container shape that accommodates the elastic member 16 therein. Both the upper side wall part 26 and the lower side wall part 28 have a ring plate shape, and are provided with circular openings 30 and 32 in the central part.

  In this example, the outer metal fitting 14 is composed of a hook-shaped first outer member 34 that opens upward, and a flat plate-like second outer member 36 that covers the upper surface opening thereof. And the lower side wall portion 28 is formed, and the second outer side member 36 forms the upper side wall portion 26.

  Specifically, the first outer member 34 includes an inversely tapered cylindrical portion 24 formed slightly larger in diameter toward the upper portion X1, and a lower side wall portion 28 extending in an inward flange shape at the lower end portion thereof. The upper end of the cylindrical portion 24 is composed of a lower flange 38 extending to the outer side Y1, and a holding portion 40 for holding a bound stopper (not shown) is provided on the lower surface side of the lower side wall portion 28. . The second outer member 36 includes the upper side wall portion 26 on the center side and the upper side flange 44 on the outer peripheral side via the stepped portion 42, and the upper side wall portion 26 slightly enters the upper surface opening of the first outer member 34. Thus, it is formed so as to slightly drop downward X2 through the step portion 42. The outer metal fitting 14 is configured to be fixed to the vehicle body panel 2 by superimposing the upper flange 44 and the lower flange 38 on the lower surface of the vehicle body panel 2 and fastening them with bolts 46 and nuts 48. ing.

  The elastic member 16 is made of a foamed urethane molded body, and is formed in a U-shaped cross section opened inwardly in Y2 so as to cover the upper surface 20A, the lower surface 20B, and the outer peripheral surface 20C of the flange portion 20 in the inner metal fitting 12. Yes.

  The elastic member 16 is divided into two on the upper and lower sides of the flange portion 20. Specifically, the elastic member 16 includes an annular upper elastic portion 50 held in the axial direction X between the upper surface 20A of the flange portion 20 and the lower surface 26A of the upper side wall portion 26, and a lower surface 20B of the flange portion 20. And an annular lower elastic portion 52 held in the axial direction X between the lower wall portion 28 and the upper surface 28A of the lower side wall portion 28, and these are separately molded by molding of a foamed urethane material.

  The elastic member 16 also includes an annular vertical wall portion 54 that connects the upper elastic portion 50 and the lower elastic portion 52, and the vertical wall portion 54 includes an outer peripheral surface 20 </ b> C of the flange portion 20 and an inner peripheral surface of the cylindrical portion 24. 24A is interposed throughout the entire circumferential direction, and has a short cylindrical shape.

  And in this example, the vertical wall part 54 is divided | segmented up and down in the center part of the height direction (axial direction X). That is, the vertical wall portion 54 includes an upper vertical wall portion 56 that protrudes integrally from the outer peripheral edge portion of the lower surface 50A of the upper elastic portion 50 toward the lower portion X2, and the outer peripheral edge portion of the upper surface 52A of the lower elastic portion 52. The lower vertical wall portion 58 integrally projecting from the upper side toward the upper side X1 and the opposing surfaces thereof (that is, the lower surface 56A of the upper vertical wall portion and the upper surface 58A of the lower vertical wall portion) are flanged to each other. It is formed by abutting on the outer periphery of the part 20.

  In the upper elastic portion 50, a concave portion 70 that extends over the entire circumference in the circumferential direction is formed in the corner 57 on the inner peripheral side of the base portion 56 </ b> B of the upper vertical wall portion 56. Also in the lower elastic portion 52, a concave portion 72 that extends over the entire circumference in the circumferential direction is formed in a corner shape at a corner portion 59 on the inner peripheral side of the base portion 58B of the lower vertical wall portion 58. As shown in FIG. 1, these recesses 70 and 72 are formed in a concave shape with a curved cross section toward the outer side in the axial direction. That is, the concave portion 70 of the upper elastic portion 50 is provided to be depressed toward the upper X1, and the concave portion 72 of the lower elastic portion 52 is provided to be depressed toward the lower X2.

The elastic member 16 is also formed of a foamed urethane molded body in which the upper elastic portion 50 has a lower hardness than the lower elastic portion 52. That is, the upper elastic part 50 is made of a soft foamed urethane molded body (for example, the density is 0.45 g / cm ³ ), and the lower elastic part 52 is a hard foamed urethane molded body (for example, the density is 0.55 g / cm 3). ³ ).

  When assembling the suspension support 10, the upper elastic portion 50 and the lower elastic portion 52 are attached from both the upper and lower sides of the inner metal fitting 12, and these are placed on the lower side wall portion 28 of the first outer member 34, from above. The second outer member 36 is covered (see FIG. 2). Then, the upper end portion 1A of the piston rod 1 is inserted and fixed to the inner metal fitting 12 using the nut 3, and the flanges 38 and 44 of the first outer member 34 and the second outer member 36 are overlapped on the lower surface of the vehicle body panel 2. Then, the bolt 46 and the nut 48 are used for fastening.

  Thereby, the upper elastic part 50 and the lower elastic part 52 formed separately are assembled as an integral elastic member 16 between the inner metal fitting 12 and the outer metal fitting 14, and the elastic member 16 is assembled by the outer metal fitting 14. It is held in a compressed state in the axial direction X. Although the compression rate in the up-down direction of the elastic member 16 is not particularly limited, it is usually compressed by 15 to 50%, and in this example, it is compressed to 40%.

  In addition, the concave portions 70 and 72 respectively formed in the upper elastic portion 50 and the lower elastic portion 52 are mostly crushed by the compression in the axial direction X, and the outer peripheral edge of the flange portion 20 of the inner metal fitting 12. A slight gap 74 is left between the upper and lower corners 20D and 20E.

  In the suspension support 10 having the above structure, since the elastic member 16 is divided into the upper and lower parts, the elastic member 16 made of a urethane foam material is formed into an undercut shape while being an elastic member 16 having a U-shaped cross section. Can be molded, and is excellent in moldability. In addition, since the inner metal fitting 12 is not integrally molded, no special equipment is required, and the manufacturing cost can be reduced. Furthermore, since the elastic member 16 molded separately is not forcibly bent at the time of assembling, it is possible to improve the durability by avoiding an undesired force distribution accompanying the bending. it can.

  In addition, since the concave portions 70 and 72 are formed in the inner peripheral corner portions 57 and 59 of the base portion of the upper and lower elastic portions 50 and 52 and the vertical wall portion 54, when the inner metal fitting 12 is displaced in the vertical direction, the corner portions 57 and 59 are formed. Durability can be improved by avoiding concentration of force on the portions 57 and 59. In particular, even after the suspension support 10 is assembled, the clearance 74 due to the recesses 70 and 72 is ensured between the upper and lower corner portions 20D and 20E of the flange portion 20 so as to be non-contacting. Can be improved.

  Further, since the recesses 70 and 72 are provided so as to be depressed outward in the axial direction, the upper and lower corners of the flange portion 20 with respect to a twisting displacement K (see FIG. 3) in which the piston rod 1 is inclined. The concentration of force at 20D and 20E can be effectively reduced. That is, at the time of twisting displacement K, the outer peripheral edge of the flange portion 20 swings in the vertical direction around the center side of the inner metal fitting 12 as indicated by the arrow K1, so that the concave portion 70 depressed in the axially outer side. , 72 can effectively eliminate the force concentration with respect to the displacement.

  Further, since the elastic member 16 is divided into the upper and lower parts, the upper and lower spring characteristics can be made different by changing the density and the like of the upper and lower urethane foam materials without depending on the shape of the elastic member 16. In this example, the upper elastic part 50 is made soft and the lower elastic part 52 is made hard. Can be improved. In addition, the effect of restricting the downward displacement of the wheel can be enhanced, so that interference between the link at the lower end of the shock absorber and members around the link can be effectively prevented.

  Further, the vertical wall portion 54 of the elastic member 16 is formed by contacting the upper vertical wall portion 56 extending from the upper elastic portion 50 and the lower vertical wall portion 58 extending from the lower elastic portion 52. The upper elastic portion 50 and the lower elastic portion 52 are formed with concave portions 50B and 52B for receiving the flange portion 20 of the inner metal fitting 12, respectively. Therefore, in the assembly process of the suspension support 10, the upper elastic portion 50 and the lower elastic portion 52 can be temporarily assembled on the upper and lower sides of the inner metal fitting 12 by holding the flange portion 20 with the concave portions 50 </ b> B and 52 </ b> B. .

(Second Embodiment)
FIG. 4 is an exploded side view of the inner metal fitting 12 and the elastic member 16 of the suspension support 10A according to the second embodiment, and FIG. 5 is a cross-sectional view in the assembly process. This embodiment is the same as the first embodiment except for the configuration of the vertical wall portion 54 of the elastic member 16. For this reason, portions with the same reference numerals have the same configuration unless otherwise described, and the description thereof is omitted.

  In this example, the vertical wall portion 54 includes a plurality of upper convex portions 60 projecting downward from a plurality of circumferential positions on the outer peripheral edge portion of the lower surface 50 </ b> A of the upper elastic portion 50, and the upper surface of the lower elastic portion 52. The plurality of lower convex portions 62 projecting upward from the plurality of locations in the circumferential direction at the outer peripheral edge of 52A are alternately fitted in the circumferential direction. The upper convex portion 60 is provided in the circumferential direction of the elastic member 16 so that the width of the convex portion 60 and the interval between the concave portions therebetween are constant, and the lower convex portion 62 is alternate with the upper convex portion 60. It is provided so as to protrude.

  And the recessed part 70 similar to 1st Embodiment is provided in the corner part of the inner peripheral side in the base part with respect to the upper side elastic part 50 of the said upper side convex part 60 over the perimeter. A similar recess 72 is also provided over the entire circumference at the inner peripheral corner of the base portion of the lower protrusion 62 with respect to the lower elastic portion 52.

  In this example, the vertical wall portion 54 is configured by meshing the convex portions 60 and 62 protruding alternately from the upper and lower elastic portions 50 and 52 as described above. Thus, in a state where the upper elastic portion 50 and the lower elastic portion 52 are temporarily assembled on both the upper and lower sides of the inner metal fitting 12, it is possible to prevent the elastic portions 50 and 52 from being detached. That is, the elastic member 16 including the inner metal fitting 12 can be handled as an integrated product when assembled to the vehicle while the elastic member 16 is a vertically divided type, and the assembly workability is excellent.

(Other embodiments)
In the above embodiment, the vertical wall portion 54 is configured by the upper and lower vertical wall portions 56 and 58 or the upper and lower convex portions 60 and 62, but only the upper elastic portion 50 or the lower elastic portion 52 has a vertical length. The entire wall portion 54 may be provided integrally. In this case, in the elastic portion 50 or 52 in which the entire vertical wall portion 54 is integrally provided, the concave portion 70 or 72 may be formed in the corner portion 57 or 59 on the inner peripheral side.

  Further, in the above-described embodiment, the gaps by the recesses 70 and 72 are secured even in the assembled state with the suspension support. However, in the assembled state, the recesses 70 and 72 are crushed so that the recesses 70 and 72 are completely crushed. It is also possible to set the depth.

  Moreover, in the said embodiment, although the upper elastic part 50 was made into the soft foaming urethane molded object and the lower elastic part 52 was made into the hard foaming urethane molded object, conversely, the upper elastic part 50 is made into the hard foaming urethane molded object. The lower elastic portion 52 may be a soft foamed urethane molded body. Moreover, it is also possible to comprise the upper elastic part 50 and the lower elastic part 52 with a foamed urethane molded body having the same hardness.
