Description

Technical Field

[0001] This invention relates to a vibration damping device with a bracket for use in engine mounts and the like in motor vehicles. Background Technology

[0002] Conventionally, as a type of vibration damping device for vehicle engine mounts, there is a known vibration damping device with a bracket in which the main body of the vibration damping device is assembled from the side onto a bracket. The main body of this vibration damping device is formed as a structure in which a first mounting member and a second mounting member, separated vertically, are elastically connected by a main body rubber elastomer. Furthermore, a pair of connecting grooves are formed on the opposing inner surfaces of the two legs of the bracket. Moreover, the main body of the vibration damping device is assembled from the side onto the bracket by inserting and fitting the pair of connecting grooves on both sides of the second mounting member of the vibration damping device main body into the pair of connecting grooves supported by the bracket.

[0003] Incidentally, in such a vibration damping device with a bracket, there is a mechanism to prevent the main body of the vibration damping device, which is assembled on the side of the bracket, from detaching from the bracket in the opposite direction to the assembly direction.

[0004] Therefore, Japanese Patent No. 5083405 (Patent Document 1) and Japanese Patent No. 6808554 (Patent Document 2) proposed the following mechanism: a second mounting member made of synthetic resin forms a locking protrusion, and the locking protrusion engages with the locking bearing part provided on the bracket by utilizing the snap-fit ​​action of the elastic deformation of the synthetic resin material, thereby preventing the vibration damping device from falling off the bracket.

[0005] However, in the mechanisms described in Patent Documents 1 and 2, when the main body of the vibration damping device is assembled to the bracket from the side, it is necessary to elastically deform the locking protrusion of the second mounting member made of synthetic resin to engage with the locking bearing part, and damage during deformation can easily become a problem.

[0006] Furthermore, because the second mounting component in the main body of the vibration damping device needs to be made of synthetic resin, it is sometimes difficult to achieve the required load-bearing capacity and strength characteristics, and there is also the potential for creep deformation and other deterioration problems over time. Especially in engine brackets and other applications with large input loads, the following potential problem exists: due to the annual deterioration of the synthetic resin, the dimensional changes of the connection part of the second mounting component create a gap between the connection part and the connecting groove of the bracket, resulting in abnormal noise caused by shaking.

[0007] Furthermore, in view of such problems, the applicant proposed the following solution in Japanese Patent No. 6644640 (Patent Document 3): the connecting portion of the vibration damping device body inserted into the connecting groove of the bracket is formed as a composite structure in which the connecting portion body, integrally formed with the second mounting member, and the force-applying rubber are integrally disposed in an overlapping state. In the connecting portion of this composite structure, when the vibration damping device body is assembled to the bracket from the side, the force-applying rubber actively deforms elastically, thereby reducing or even avoiding deformation of the connecting portion body and preventing damage during assembly. In addition, the second mounting member having the connecting portion body can be made of metal, thereby advantageously ensuring the load-bearing performance and strength characteristics of the second mounting member and the connecting portion body, and also preventing creep deformation and other deterioration over time.

[0008] However, the inventors of this invention further discovered that the vibration damping device with bracket disclosed in Patent Document 3 also has room for further improvement. That is, in the vibration damping device with bracket disclosed in Patent Document 3, in the opposing direction of a pair of connecting grooves provided on the bracket, a pair of connecting parts of the main body of the vibration damping device are positioned and supported by force-applying rubber provided on the outer peripheral surface abutting against the bottom surface of the grooves of a pair of connecting grooves.

[0009] Therefore, in the opposing direction of the pair of connecting grooves, the vibration damping device is positioned relative to the bracket by balancing the force-applying rubbers on both sides, making it difficult to achieve high-precision position setting. Furthermore, when a large input load is applied to one side of the pair of connecting grooves in the opposing direction, the clamping force-applying rubbers may prevent the achievement of sufficient load-bearing capacity.

[0015] The problem that the invention aims to solve

[0016] The present invention was made against the background described above, and the problem it aims to solve is to provide a novel vibration damping device with a bracket. Compared with the vibration damping devices with brackets described in Patent Documents 1 and 2, this vibration damping device with bracket has a novel detachment prevention mechanism that prevents damage to the connecting parts, etc., when the main body of the vibration damping device is assembled to the bracket from the side. It can achieve improvements in load-bearing characteristics and suppression of deterioration over time. Furthermore, compared with the vibration damping device with bracket described in Patent Document 3, it can achieve improvements in the positioning accuracy of the main body of the vibration damping device relative to the bracket in the opposing direction of a pair of connecting grooves and improvements in the load-bearing performance on one side.

[0017] means for solving problems

[0018] Hereinafter, embodiments of the present invention, completed to solve such problems, are described. Furthermore, the constituent elements employed in the embodiments described below can be used in as many arbitrary combinations as possible.

[0019] The first aspect of the present invention is as follows.

[0020] A vibration damping device with a bracket, wherein the main body of the vibration damping device, which consists of a first and a second mounting component that are separated vertically, is elastically connected by a main body rubber elastomer, is assembled from the side onto the bracket by inserting a pair of connecting portions provided on both sides of the second mounting component into a pair of connecting grooves provided on opposite inner surfaces of the legs on both sides of the bracket.

[0021] The pair of connecting portions of the second mounting member and the pair of connecting grooves of the bracket are both made of metal.

[0022] One of the connecting parts exposes metal on its outer peripheral surface and lower surface to make metal contact with the bottom surface and lower surface of the connecting groove of one side, and an upper force-applying rubber is provided on its upper surface to abut against the upper surface of the connecting groove of one side.

[0023] The connecting part of the other party has metal exposed on its lower surface, making metal contact with the lower surface of the connecting groove of the other party. It also has an upper-side force-applying rubber on its upper surface, which abuts against the upper surface of the connecting groove of the other party. Furthermore, it has an outer-peripheral force-applying rubber on its outer circumferential surface, which abuts against the bottom surface of the connecting groove of the other party.

[0024] The force generated by the outer peripheral force-applying rubber of the connecting portion on the other side is applied laterally to the second mounting member, thereby pressing the outer peripheral surface of the connecting portion of one side of the second mounting member into the bottom surface of the connecting groove of the other side in a metal-to-metal contact manner. On the other hand,

[0025] Anti-disengagement engagement portions are provided between the outer peripheral surface of the connecting portion of one party and the connecting groove of the other party, and between the inner peripheral surface of the connecting portion of the other party and the connecting groove of the other party. The anti-disengagement engagement portions are held in an engaged state by the force generated by the outer peripheral force-applied rubber, thereby preventing the connecting portions inserted into the connecting grooves from disengaging.

[0026] In this type of vibration damping device with a bracket, when the connecting parts are inserted into the connecting grooves and the main body of the vibration damping device is assembled onto the bracket in a pressed-in state, the upper part is subjected to force in the vertical direction, resulting in elastic deformation of the rubber, and the outer periphery is subjected to force in the opposite direction of the pair of connecting grooves, resulting in elastic deformation of the rubber. Therefore, elastic deformation of the connecting parts is not required. Thus, by making the second mounting member including the connecting parts metal, damage to the second mounting member, including the connecting parts, can be prevented when assembling the main body of the vibration damping device onto the bracket. Furthermore, problems such as shaking and reduced strength caused by creep deformation and other deterioration over time in resin-made components can be avoided.

[0027] Furthermore, the pair of connecting portions provided on the second mounting member made of metal are pressed against the connecting groove of the bracket in a metal-to-metal contact manner on the lower surface by the force of the upper force-applying rubber provided on each upper surface. Therefore, it is possible to achieve improved load-bearing performance in the bounce direction (downward), which is particularly easy to be subjected to large loads.

[0028] Furthermore, due to the force of the rubber applied to the outer periphery of the connecting part of one party, the outer peripheral surface of the connecting part of the other party is pressed against the bottom surface of the groove of the connecting part of one party in a metal-to-metal contact manner. Therefore, in the opposing direction of the pair of connecting grooves, the positioning accuracy of the vibration damping device body relative to the bracket can be well ensured. In addition, the load-bearing performance can be improved in the direction in which the connecting part of one party is pressed against the bottom surface of the groove of the connecting part of the other party in a metal-to-metal contact manner.

[0029] Furthermore, between a pair of connecting slots and a pair of connecting parts inserted therein, anti-disengagement locking parts are provided to prevent each connecting part from disengaging from each connecting slot. This provides a greater disengagement-preventing force, and even if a large load is input in the disengagement direction, it can effectively suppress the rotational displacement of the vibration damping device body and the generation of torque in the rotational direction, thereby maintaining the assembly state of the vibration damping device body relative to the bracket more stably.

[0030] The second aspect of the present invention is described below.

[0031] According to the vibration damping device with bracket described in the first method, wherein,

[0032] The anti-detachment locking part comprises:

[0033] A one-sided interlocking portion, wherein a stepped protrusion provided on the bottom surface of the groove of the connecting groove of the one-sided portion engages with a stepped recess provided on the outer peripheral surface of the connecting portion of the one-sided portion; and

[0034] In the other concave-convex engaging portion, a stepped protrusion provided on the inner wall portion protruding from the bottom surface of the groove of the connecting groove portion of the other party engages with a stepped concave portion provided on the inner circumferential surface of the connecting portion of the other party.

[0035] In this type of bracket-type vibration damping device, the stepped surfaces of the recesses of each connecting part and the stepped surfaces of the convex parts of each connecting groove can be engaged to prevent the connecting parts inserted into the connecting grooves from coming out. Furthermore, the stepped surfaces of the recesses of the interlocking connecting parts and the stepped surfaces of the convex parts of each connecting groove can be designed as metal-to-metal contact surfaces. Therefore, the anti-disengagement engagement part can be constructed with greater strength and positioning performance, and the load-bearing capacity in the disengagement direction of the bracket-type vibration damping device can also be advantageously ensured.

[0036] The third aspect of the present invention is described below.

[0037] According to the first or second method of the anti-vibration device with bracket, in the anti-disengagement engagement portion, the locking surfaces that lock against each other in the disengagement direction of the connecting portion inserted into the connecting groove portion are set to be located in the central region that is divided into three equal parts in the assembly direction of assembling the second mounting member toward the bracket.

[0038] In this type of vibration damping device with a bracket, the position of the locking surface of the anti-detachment engagement part can be set close to the central axis extending vertically of the vibration damping device body in the assembly direction of the vibration damping device body relative to the bracket. Therefore, for example, the locking action of the locking surfaces of the anti-detachment engagement parts provided on both sides can effectively prevent swaying in the rotational direction of the vibration damping device body about the central axis.

[0039] The fourth aspect of the present invention is described below.

[0040] According to any one of the first to third methods, the anti-disengagement engagement portion is partially provided in the vertical direction of the connecting portion of one of the methods.

[0041] In the bracketed vibration damping device of this method, anti-disengagement engagement parts, such as protrusions in the connecting part and recesses in the connecting groove, are partially provided in the vertical direction, thereby ensuring a larger area of ​​metal contact between the outer peripheral surface of one connecting part and the bottom surface of the groove of one connecting groove.

[0042] The fifth aspect of the present invention is described below.

[0043] According to any one of the first to fourth methods, the vibration damping device with bracket is provided with a front force-applying rubber on the front end face of the second mounting member in the assembly direction from the side toward the bracket and abuts against the bracket in the assembly direction.

[0044] In this type of vibration damping device with bracket, the force generated by the front-end force-applying rubber is applied to the main body of the vibration damping device in the opposite direction to the assembly direction of the bracket. This keeps the connecting part in an abutting engagement state that prevents it from coming out of the connecting groove in the anti-disengagement engagement part, thereby stabilizing the positioning state of the connecting part relative to the insertion direction of the connecting groove and also helping to prevent shaking.

[0045] The sixth aspect of the present invention is described below.

[0046] According to any one of the first to fifth embodiments, the vibration damping device with bracket is provided with a guide cone that is inclined such that the groove depth increases from the inside of the insertion direction of the connection part toward the opening side on the bottom surface of the groove of the connection groove.

[0047] In this type of vibration damping device with bracket, the insertion of the connecting part relative to the connecting groove is facilitated by the guide cone. Even when the force of the rubber applied to the outer periphery of the connecting part is set to be large, the workability of inserting the connecting part into the connecting groove and the workability of assembling the main body of the vibration damping device into the bracket can be well maintained.

[0048] Invention Effects

[0049] According to the present invention, the second mounting member including the connecting portion can be made of metal. Furthermore, in the vertical direction, the opposing direction of a pair of connecting grooves, and the assembly direction of the vibration damping device body towards the bracket, the second mounting member can be supported in a positioning state by the metal contact between the connecting portion and the bracket.

[0050] Therefore, compared to the vibration damping device with bracket described in Patent Documents 1 and 2, for example, damage to the connecting parts during the assembly of the vibration damping device body to the bracket can be prevented, and the creep deformation and other deterioration of the connecting parts over time can also be avoided. In addition, compared to the vibration damping device with bracket described in Patent Document 3, the positioning accuracy of the vibration damping device body relative to the bracket in the opposing direction of a pair of connecting grooves can also be improved.

Detailed Implementation

[0070] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

[0071] exist Figures 1-7In this paper, an engine mount 10 for a motor vehicle is shown as one embodiment of a vibration damping device with a bracket, formed according to the structure of the present invention. The engine mount 10 is formed by laterally inserting the mount body 12, which serves as the main body of the vibration damping device, into the bracket 14 in a so-called lateral insertion assembly. In the following description, in principle, the vertical direction refers to the direction along the central axis of the mount. Figure 3 The vertical direction within. Additionally, assuming the engine mount 10 of this embodiment will... Figure 3 The vertical direction in the diagram is defined as the vertical direction, the left and right direction as the front and rear direction of the vehicle, and the vertical direction on the paper as the left and right direction of the vehicle. It is then assembled between the vehicle body and the power unit. However, the ease of understanding shown in the attached diagram takes precedence. In the following description, [the following will be used as an example]. Figure 3 The left and right directions in the figure are called the left and right directions of the bracket, and the direction perpendicular to the paper in the figure is called the front and back direction of the bracket (or the inward / near front direction). In addition, in each figure, in order to easily understand the presence or absence of compression in the assembled state of the bracket 14, each rubber elastomer (force-applying rubber) provided on the bracket body 12 is shown in a way that maintains its shape before assembly with the bracket 14.

[0072] More specifically, the main body 12 of the support, in addition to Figures 1-7 In addition, such as Figures 8-11 As shown in single-piece form, it has a structure in which a first mounting member 20 and a second mounting member 22 are elastically connected by a main rubber elastomer 24. The support load and vibration of the power unit are input between the first mounting member 20 and the second mounting member 22.

[0073] The first mounting component 20 is a high-rigidity component made of metal or the like, formed into a solid block structure such as a frustum-shaped cone with reversed top and bottom. For example... Figures 1-4 As exemplified, the mounting member 26, which is installed on the power unit, etc., is fixed to the first mounting member 20 by fixing bolts, etc.

[0074] The second mounting component 22 is a high-rigidity component made of metals such as aluminum alloy and steel, and is formed as a whole into a generally thick-walled annular block, especially in this embodiment. Figure 6 It can be understood that the central perforation is a rounded rectangular shape, and the whole structure is formed into a roughly rectangular, thick-walled, annular block.

[0075] The main rubber elastomer 24, which elastically connects the first mounting member 20 and the second mounting member 22, is formed with an outer peripheral surface that is generally elliptical or rounded rectangular in the circumferential direction and whose outer diameter gradually decreases from bottom to top. Furthermore, the first mounting member 20 is fixed to the upper small-diameter portion in a substantially embedded manner, and the second mounting member 22 is fixed to the lower large-diameter outer peripheral portion. Preferably, the main rubber elastomer 24 is formed as an integrally vulcanized molded part comprising the first mounting member 20 and the second mounting member 22.

[0076] The main rubber elastomer 24 has a reverse recess 28 with an opening at the center of its lower surface, which opens downward through a through-hole in the second mounting member 22. Additionally, a sealing member 30 is superimposed and assembled from below on the second mounting member 22.

[0077] The sealing member 30 is formed from a rigid synthetic resin material or the like, and is shaped into a generally thick-walled annular block corresponding to the second mounting member 22. Furthermore, the sealing member 30 has a support base 32 protruding inward from its lower end, and the cross-sectional shape of the sealing member 30 is generally L-shaped. A flexible diaphragm 34 and a throttling member 36 are inserted into the sealing member 30 from above, and assembled in a receiving state by overlapping the support base 32. Moreover, the flexible diaphragm 34 and the throttling member 36 are fixedly supported by being clamped vertically between the second mounting member 22 and the sealing member 30 at their respective outer peripheral portions.

[0078] Furthermore, on the upper side of the sealing member 30, the second mounting member 22 is sealed to the sealing member 30 and the throttling member 36 by clamping the sealing rubber 38 disposed on the lower surface of the second mounting member 22. Additionally, on the lower side of the sealing member 30, the sealing member 30 and the throttling member 36 are sealed by clamping the outer periphery of the flexible membrane 34 between the upper and lower parts.

[0079] Thus, the recess 28 of the main rubber elastomer 24 is covered by the flexible membrane 34 and liquid-tightly sealed, thereby dividing the liquid chamber 40 into which a predetermined liquid is sealed. Furthermore, this liquid chamber 40 is divided vertically by a generally plate-shaped throttling member 36. Moreover, on the upper side of the throttling member 36, a pressure chamber 42 is formed, in which a portion of the wall is made of the main rubber elastomer 24 and pressure fluctuations occur with vibration input. Additionally, on the lower side of the throttling member 36, a variable-volume equilibrium chamber 44 is formed, in which a portion of the wall is made of a flexible membrane 34 such as a diaphragm rubber, absorbing pressure fluctuations.

[0080] The aforementioned pressure chamber 42 and balance chamber 44 are connected by a throttling passage 46 provided in the throttling member 36, which provides a vibration damping effect by utilizing the flow of fluid flowing through the throttling passage 46 when vibration is input. Furthermore, in this embodiment, a receiving region is formed in the central portion of the throttling member 36, communicating with both the pressure chamber 42 and the balance chamber 44, respectively. A movable diaphragm 48 is housed in this receiving region. Moreover, for example, when vibration is input in the high-frequency domain exceeding the tuning frequency of the throttling passage 46, the pressure fluctuations in the pressure chamber 42 are reduced or even absorbed based on the deformation or displacement of the movable diaphragm 48, avoiding significant high-dynamic springing.

[0081] Furthermore, the specific structure of the liquid chamber 40, the tuning characteristics of the throttling path 46, and the presence or absence of a high-frequency hydraulic absorption mechanism based on the movable diaphragm 48 are not limited, and can be appropriately set according to the required anti-vibration characteristics. In addition, the assembly structure of the sealing member 30 relative to the second mounting member 22 is not limited. In this embodiment, a locking mechanism formed by a hook using a resin hook is adopted.

[0082] That is, the locking mechanism consists of locking claws 50 protruding from the outer peripheral surface of the second mounting member 22 and flexible locking tabs 52 extending upward from the outer peripheral surface of the sealing member 30. The locking claws 50 and locking tabs 52 are arranged in pairs at corresponding positions, and multiple pairs are provided in the circumferential direction of the second mounting member 22 and the sealing member 30. Particularly in this embodiment, in the second mounting member 22 and the sealing member 30, two pairs of locking claws 50 and locking tabs 52 are provided on each side of each front-rear direction, extending in a substantially linear manner.

[0083] The locking tab 52 is formed in a generally inverted U-shape and has locking holes extending vertically in the central portion. By hooking the locking claws 50 into these locking holes, the sealing member 30 is assembled and fixed to the second mounting member 22. Furthermore, the hooking of each locking claw 50 onto each locking tab 52 is achieved by overlapping the upper surface of the sealing member 30 with the lower surface of the second mounting member 22 from below, so that they approach each other while pressing the sealing rubber 38. This allows the locking tabs 52 to hook approximately simultaneously by utilizing their elastic deformation and recovery.

[0084] Furthermore, on the second mounting member 22, which is equipped with the sealing member 30, a pair of connecting portions 54a and 54b are respectively provided on the outer periphery of the left and right sides where the locking claws 50 are not formed. These portions extend in a straight line in the front-back direction with approximately a certain thickness. Moreover, in the assembled state where the bracket body 12 is assembled to the bracket 14, the second mounting member 22 is fixedly supported by the bracket 14 using the aforementioned connecting portions 54a and 54b.

[0085] The bracket 14 is a high-rigidity component made of metals such as aluminum alloy and fiber-reinforced resin, in addition to Figures 1-7 In addition, such as Figures 12-14 As shown, the assembly bracket body 12 integrally comprises left and right mounting legs 60, 60 that rise upward from the upper surface of a generally rectangular flat base portion 58, and a top plate portion 62 that integrally connects the upper ends of the left and right mounting legs 60, 60. Furthermore, the assembly space 66 of the assembly bracket body 12 is formed to open to the side when surrounded by the base portion 58, the left and right mounting legs 60, 60 and the top plate portion 62.

[0086] Furthermore, on the inner side of the assembly space 66 (the side opposite to the side opening), an inner wall 68 is integrally provided to close the opening of the assembly space 66, and an insertion hole 70 is formed on the upper part of the inner wall 68 for inserting the mounting member 26 and assembling it into the bracket body 12 (first mounting member 20). In addition, the two sides of the base portion 58 are formed as fixing plate portions extending outward from each mounting leg portion 60, in which the bracket 14 is bolted to the side of the vehicle body.

[0087] The left and right mounting legs 60, 60 are formed as thick-walled plates with a predetermined width in the front-back direction, and are positioned opposite each other on the left and right sides. In addition, the left and right mounting legs 60, 60 are formed with connecting grooves 72a, 72b that open on the opposing inner surfaces and extend in the front and back.

[0088] Furthermore, relative to the aforementioned pair of connecting slots 72a and 72b, a pair of connecting portions 54a and 54b, which are inserted from the side into the second mounting member 22 provided on the bracket body 12, such as in Figures 15-17 As shown in the intermediate assembly steps, the bracket body 12 is inserted laterally and assembled onto the bracket 14. Furthermore, in this assembled state, the lower surface of the bottom wall of the sealing member 30 of the bracket body 12 overlaps with and is supported by the upper surface of the base portion 58 of the bracket 14 in an abutting state.

[0089] Here, each pair of connecting portions 54a, 54b and connecting groove portions 72a, 72b has a special configuration so that when the bracket body 12 is assembled on the bracket 14, the connecting portions 54a, 54b of the second mounting member 22 are positioned and fixedly supported by the connecting groove portions 72a, 72b of the bracket 14.

[0090] Specifically, each connecting portion 54a, 54b of the second mounting member 22 extends a predetermined length from the left and right ends of the second mounting member 22 and has a middle portion in the front-rear direction. On the lower surfaces 74, 74 of the pair of connecting portions 54a, 54b, the second mounting member 22, made of metal, is exposed, and together with the lower surfaces 76, 76 of the corresponding connecting groove portions 72a, 72b, they extend linearly in the front-rear direction with a generally horizontal and flat metal surface.

[0091] Furthermore, the upper surfaces 78, 78 of the pair of connecting portions 54a, 54b and the upper surfaces 80, 80 of the grooves of the pair of connecting groove portions 72a, 72b can also be formed as flat surfaces extending approximately horizontally in the front-rear direction. However, in this embodiment, the upper surfaces 80, 80 of the grooves of the connecting groove portions 72a, 72b are respectively formed to extend towards the opening for a predetermined length covering the opening side (near the front side). Figure 7 The inclined surface, which gradually slopes upward from the right end of the middle, improves the operability of inserting the connecting parts 54a and 54b.

[0092] from Figure 7 It can be understood that the thickness of the pair of connecting portions 54a and 54b in the vertical direction is slightly smaller than the vertical dimension (groove width) of the pair of connecting groove portions 72a and 72b. In addition, upper force-applying rubber 82 and 82 are respectively provided on the upper surfaces 78 and 78 of the pair of connecting portions 54a and 54b.

[0093] The thickness of the upper force-applying rubber 82 (the protruding height from the connecting portions 54a, 54b) is greater than the difference between the vertical thickness of the connecting portions 54a, 54b and the vertical dimension of the connecting grooves 72a, 72b. Therefore, when the pair of connecting portions 54a, 54b are inserted into the pair of connecting grooves 72a, 72b and assembled into the second mounting member 22 of the bracket 14, the upper force-applying rubber 82, 82, compressed by contact with the upper surfaces 80, 80 of the connecting grooves 72a, 72b, is pressed against the lower surfaces 76, 76 of the connecting grooves 72a, 72b in a metal-to-metal contact manner and positioned.

[0094] Additionally, the outer peripheral surfaces 84, 84 of the pair of connecting portions 54a, 54b may also have a constant width in the vertical direction and extend parallel to each other in the front-back direction, but in this embodiment, they are formed from the inside ( Figure 6 The upper side, i.e. the front, faces forward ( Figure 6 The sloping surface whose height gradually increases slightly from the lower side (i.e., the rear) outwards.

[0095] from Figure 6It can be understood that the left-right separation dimension between the outer peripheral surfaces 84, 84 of the pair of connecting portions 54a, 54b, that is, the outer dimension of the second mounting member 22 in the left-right direction at the forming part of the connecting portions 54a, 54b, is slightly smaller than the distance between the opposing surfaces of the inner bottom surfaces 86, 86 of the pair of connecting groove portions 72a, 72b. Furthermore, one of the connecting portions ( Figure 2 , Figure 3 , Figure 5 , Figure 6 The outer peripheral surface 84 of the left connecting part 54a is formed as a metal surface exposed by the second mounting member 22 made of metal, which overlaps with the metal surface of the bottom surface 86 of the groove of one of the connecting grooves 72a.

[0096] Furthermore, the inner bottom surfaces 86, 86 of the pair of connecting grooves 72a, 72b are formed into planar shapes corresponding to the outer peripheral surfaces 84, 84 of the pair of connecting parts 54a, 54b, and abut against each other in a metal-to-metal contact manner covering approximately the entire surface. That is, in this embodiment, the inner bottom surfaces 86, 86 of the pair of connecting grooves 72a, 72b and the outer peripheral surfaces 84, 84 of the pair of connecting parts 54a, 54b are formed as inclined surfaces in which the distance between the opposing surfaces of the pair of inner bottom surfaces 86, 86 gradually increases from the inside towards the front. In particular, in this embodiment, the opposing inner surfaces of the pair of mounting legs 60, 60 of the bracket 14 are formed almost entirely as inclined surfaces in which the distance between the opposing surfaces gradually increases from the inside towards the front, thereby forming a groove depth dimension of approximately constant from the front towards the inside of the connecting grooves 72a, 72b with inclined inner bottom surfaces 86.

[0097] Furthermore, on the outer peripheral surface 84 of the other connecting portion 54b, a peripheral force-applying rubber 88 is provided covering approximately the entire surface. The thickness of this peripheral force-applying rubber 88 (the protrusion height from the connecting portion 54b to the side) is greater than the difference between the left and right separation dimension between the outer peripheral surfaces 84, 84 of the pair of connecting portions 54a, 54b and the distance between the opposing surfaces of the inner bottom surfaces 86, 86 of the pair of connecting grooves 72a, 72b.

[0098] Thus, by inserting a pair of connecting portions 54a, 54b into a pair of connecting grooves 72a, 72b and assembling them into the second mounting member 22 of the bracket 14, the outer peripheral force-applying rubber 88, which is compressed by the contact between the connecting portion 54b side and the bottom surface 86 of the groove of the connecting groove 72b side, is pressed against the bottom surface 86 of the groove of the connecting groove 72a side in a metal-to-metal contact manner and is thus positioned.

[0099] Furthermore, anti-disengagement locking parts are provided between one connecting part 54a and one connecting groove 72a, and between the other connecting part 54b and the other connecting groove 72b. These anti-disengagement locking parts are kept in a locked state by the force generated by the outer peripheral force-applying rubber 88, preventing the pair of connecting parts 54a and 54b inserted into the pair of connecting grooves 72a and 72b from disengaging.

[0100] In this embodiment, the anti-disengagement engagement portion between the connecting portion 54a of one party and the connecting groove portion 72a of the other party is composed of a stepped recess 90 provided on the outer peripheral surface 84 of the connecting portion 54a of one party and a stepped protrusion 92 provided on the bottom surface of the groove of the connecting groove portion 72a of one party.

[0101] The stepped recess 90 of one of the connecting portions 54a is formed on the outer peripheral surface 84 of the connecting portion 54a in a cut shape extending from the rear end toward the front and approximately to the center. The stepped surface, which serves as the front end face of the stepped recess 90, forms a locking surface 94 that is orthogonal to the front-rear direction and extends in the up-down and left-right directions. In particular, in this embodiment, the stepped recess 90 is formed to a size extending from the lower end of the connecting portion 54a to the middle portion in the up-down direction. Therefore, in one of the connecting portions 54a, the contact area that abuts against the bottom surface 86 of the connecting groove portion 72a in a metal-to-metal contact manner is prevented from being significantly damaged by the stepped recess 90, thereby improving the load-bearing capacity and other properties of the metal contact surface.

[0102] One of the connecting groove portions 72a has a stepped protrusion 92 formed in the groove bottom surface 86 of the connecting groove portion 72a in the shape of a protrusion extending from the rear end toward the front to approximately the center. The stepped surface, which is the front side end face of the stepped protrusion 92, forms a locking surface 96 that is orthogonal to the front-rear direction and extends in the up-down and left-right directions. In particular, in this embodiment, the stepped protrusion 92 is formed to a size from the lower end of the groove bottom surface 86 of the connecting groove portion 72a to the middle portion in the up-down direction.

[0103] Thus, the stepped protrusion 92 of the connecting groove 72a enters and is substantially accommodated in the stepped recess 90 of the connecting portion 54a. The locking surface 94 of the connecting portion 54a abuts against the locking surface 96 of the stepped protrusion 92 from the inside toward the front, thereby preventing the connecting portion 54a inserted into the connecting groove 72a from dislodging toward the front. In particular, in this embodiment, the load-bearing capacity is improved by overlapping the mutually abutting locking surfaces 94 and 96 in a metal-to-metal contact manner. In addition, by setting the abutting position of the two locking surfaces 94 and 96 to be located in the assembly direction of assembling the second mounting member 22 toward the bracket 14 ( Figure 5Within the central region (divided into three equal parts in the vertical direction), for example, the swaying of the support body 12 in the direction of rotation around the central axis can also be effectively suppressed by the locking effect generated by the contact of the two locking surfaces 94 and 96.

[0104] In addition, in this embodiment, the anti-disengagement engagement portion between the connecting portion 54b of the other party and the connecting groove portion 72b of the other party is composed of a stepped recess 100 provided on the inner side of the connecting portion 54b of the other party and a stepped protrusion 102 provided on the opening of the connecting groove portion 72b of the other party.

[0105] That is, a front and rear groove 104 with an opening on the lower surface and extending in the front-rear direction is formed on the inner peripheral side of the connecting portion 54b on the other side. On the outer wall surface of the front and rear groove 104, a stepped recess 100 is formed in the shape of a cut extending from the rear end toward the front to approximately the center. Moreover, the stepped surface, which is the front side end face of the stepped recess 100, forms a locking surface 106 in a plane that is orthogonal to the front-rear direction and extends in the up-down and left-right directions.

[0106] The stepped protrusion 102 of the connecting groove 72b is formed by an inner wall portion that protrudes upward from the lower surface 76 inside the groove of the connecting groove 72b. That is, the inner wall portion 102, which is the stepped protrusion, is formed as a vertical wall shape that extends from the rear end of the connecting groove 72b toward the front to approximately the center along the opening edge of the connecting groove 72b with a substantially constant cross-sectional shape. Moreover, the stepped surface, which is the front side end face of the stepped protrusion 102, forms a locking surface 108 with a plane that is orthogonal to the front-rear direction and extends in the up-down and left-right directions.

[0107] Thus, the stepped protrusion (inner wall portion) 102 of the connecting groove 72b enters and is substantially accommodated in the stepped recess 100 of the connecting portion 54b. The locking surface 106 of the connecting portion 54b abuts against the locking surface 108 of the stepped protrusion 102 from the inside toward the front, thereby preventing the connecting portion 54b inserted into the connecting groove 72b from dislodging toward the front. In particular, in this embodiment, the load-bearing capacity is improved by overlapping the mutually abutting locking surfaces 106 and 108 in a metal-to-metal contact manner.

[0108] Furthermore, in this embodiment, the locking surfaces 94 and 96 of the anti-detachment engagement portion of one connecting portion 54a and the connecting groove portion 72a, and the locking surfaces 106 and 108 of the anti-detachment engagement portion of the other connecting portion 54b and the connecting groove portion 72b, are positioned approximately at the same location in the front-rear direction, and are located on the left and right sides along a straight line including the central axis of the bracket. This allows for a more stable and effective exertion of the detachment-preventing force that prevents the bracket body 12 from detaching from the bracket 14.

[0109] Furthermore, in the assembled state where the bracket body 12 is assembled onto the bracket 14, the stepped recess 90 and stepped protrusion 92 in the anti-detachment engagement portion of one connecting portion 54a and the connecting groove 72a, and the stepped recess 100 and stepped protrusion 102 in the anti-detachment engagement portion of the other connecting portion 54b and the connecting groove 72b, can all be formed to abut against each other in the left-right direction, but it is preferable that they are opposed in the left-right direction with a small gap. This allows for a more stable display of the abutment state in the metal-to-metal contact between the outer peripheral surface 84 of one connecting portion 54a and the bottom surface 86 of the groove of one connecting groove 72a.

[0110] Incidentally, such as Figures 15-17 As shown, the second mounting member 22, which is assembled with a pair of connecting portions 54a and 54b as described above to a pair of connecting slots 72a and 72b, is fixedly supported to the bracket 14 by inserting and pushing the pair of connecting portions 54a and 54b from the front toward the inside relative to the pair of connecting slots 72a and 72b, and pressing them in until the second mounting member 22 reaches a position where it is approximately accommodated in the bracket 14.

[0111] First, such as Figure 15 As shown, the bracket body 12 is inserted into the assembly space 66 of the bracket 14, and the pair of connecting portions 54a and 54b of the second mounting member 22 are inserted into the pair of connecting grooves 72a and 72b of the bracket 14 from the opening near the front. At this time, the distance between the opposing surfaces of the inner bottom surfaces 86 and 86 of the pair of connecting grooves 72a and 72b increases from the inside towards the front and then to the left and right, and the left and right dimensions between the outer peripheral surfaces 84 and 84 of the pair of connecting portions 54a and 54b decrease towards the front (inside) in the insertion direction, so the pair of connecting portions 54a and 54b can be easily inserted into the pair of connecting grooves 72a and 72b. In particular, the inclination angle of the other connecting groove 72b towards the outside of the inner bottom surface 86 near the end near the front is further increased (see reference). Figure 6 , Figure 14 (etc.) to prevent the outer peripheral rubber 88 from getting caught. Additionally, in the vertical direction, the upper surface 80 inside each connecting groove 72a, 72b gradually slopes upwards from the inside towards the front, especially near the end on the front side, where the angle of inclination further increases (see reference). Figure 7 , Figure 15(etc.), thereby preventing the upper force-applying rubbers 82, 82 from hooking, and making it easier to insert the connecting parts 54a, 54b relative to the connecting grooves 72a, 72b. In addition, by reducing the rubber thickness at the front end in the insertion direction and forming a tapered shape that gradually thickens towards the rear in the insertion direction, it is possible to make it easier to insert the connecting parts 54a, 54b relative to the connecting grooves 72a, 72b.

[0112] Furthermore, such as Figure 16 As shown, when a pair of connecting portions 54a and 54b inserted into a pair of connecting slots 72a and 72b of the bracket 14 are pushed inward, the lower surfaces 74 and 74 of each connecting portion 54a and 54b overlap with the lower surfaces 76 and 76 inside the slots of the connecting slots 72a and 72b in a metal-to-metal contact manner, and the flat lower surfaces 74 and 74 are guided to move inward by sliding on the flat lower surfaces 76 and 76 inside the slots. In addition, in the other connecting portion 54b, the outer peripheral force-applying rubber 88 abuts against the bottom surface 86 inside the slot of the other connecting slot 72b, and the second mounting member 22 is pressed to the left as a whole by its compressive reaction force. However, the outer peripheral surface 84 of one of the connecting portions 54a abuts against the stepped protrusion (inner wall portion) 92 formed on one of the connecting groove portions 72a, and moves inward on the stepped protrusion 92 in a state of moving away from the bottom surface 86 inside the groove of the connecting groove portion 72a.

[0113] Then, as Figure 17 As shown, if a pair of connecting portions 54a and 54b are pushed inward along a pair of connecting grooves 72a and 72b of the bracket 14, the locking surface 94 of the stepped recess 90 formed on one of the connecting portions 54a reaches the locking surface 96 of the stepped protrusion 92 of the connecting groove 72a, thereby disengaging the outer peripheral surface 84 of the connecting portion 54a from its contact with the stepped protrusion (inner wall portion) 92 formed on the connecting groove 72a. Approximately simultaneously, the locking surface 106 of the stepped recess 100 formed on the other connecting portion 54b reaches the locking surface 108 of the stepped protrusion 102 of the connecting groove 72b, thereby disengaging the outer peripheral surface 84 of the other connecting portion 54b from its contact with the stepped protrusion (inner wall portion) 102 formed on the connecting groove 72b. As a result, the second mounting member 22 moves to the left due to the compressive reaction force of the outer peripheral rubber 88. Consequently, the outer peripheral surface 84 of one of the connecting portions 54a can be pressed against the bottom surface 86 of the groove of one of the connecting groove portions 72a in a metal-to-metal contact manner.

[0114] In addition, such as Figure 17As shown, in the assembled state where a pair of connecting portions 54a and 54b are pushed to their innermost positions relative to a pair of connecting grooves 72a and 72b, the locking surface 94 of the stepped recess 90 of one connecting portion 54a overlaps with the locking surface 96 of the stepped protrusion 92 of one connecting groove 72a from the inside toward the front in the assembly direction of the second mounting member 22 relative to the bracket 14, and abuts in a metal-to-metal contact. Furthermore, the locking surface 106 of the stepped recess 100 of the other connecting portion 54b overlaps with the locking surface 108 of the stepped protrusion 102 of the other connecting groove 72b from the inside toward the front in the assembly direction of the second mounting member 22 relative to the bracket 14, and abuts in a metal-to-metal contact. Through the abutment of one and the other sides, the second mounting member 22 is prevented from dislodging from the bracket 14.

[0115] In particular, in this embodiment, a front-end force-applying rubber 112 protruding outward (inward) is provided on the front end face of the second mounting member 22 in the assembly direction relative to the bracket 14. Figure 17 In the assembled state, the front-end force-applying rubber 112 abuts against the inner wall 68 of the bracket 14, and its elastic abutment reaction force presses the locking surfaces 94, 106 of the connecting parts 54a, 54b and the locking surfaces 96, 108 of the connecting grooves 72a, 72b in the abutment direction. Thus, the locking surfaces 94, 106 of the connecting parts 54a, 54b and the locking surfaces 96, 108 of the connecting grooves 72a, 72b are held in abutment, thereby preventing shaking, etc.

[0116] As can be seen from the above description, the second mounting member 22 is positioned relative to the bracket 14 in a metal-to-metal contact manner in the vertical direction, and also in a metal-to-metal contact manner in the horizontal direction, and further in a metal-to-metal contact manner in the front-back direction. Therefore, the second mounting member 22 can be positioned and supported on the bracket 14 with high precision and large load-bearing capacity.

[0117] Furthermore, when assembling the second mounting member 22 onto the bracket 14, the flat lower surfaces 74, 74 of the pair of connecting portions 54a, 54b are guided to slide on the flat lower surfaces 76, 76 of the pair of connecting grooves 72a, 72b, allowing the second mounting member 22 to move approximately parallel during assembly. This prevents the second mounting member 22 from tilting relative to the bracket 14 during assembly. Therefore, the assembly of the second mounting member 22 onto the bracket 14 can be easily performed, and, for example, when assembling the second mounting member 22 onto the bracket 14, it is also possible to avoid localized and temporary reductions in the sealing performance between the second mounting member 22 and the sealing member 30, or leakage, caused by the overall tilting of the bracket body 12, which could result in the sealing member 30, which is engaged with the second mounting member 22, strongly contacting the base portion 58 of the bracket 14.

[0118] The embodiments of the present invention have been described in detail above, but the present invention is not limited to this specific description. For example, the upper force-applying rubber 82, the outer peripheral force-applying rubber 88, etc., can be integrally formed with the main rubber elastomer 24, or they can be formed separately. In addition, the upper force-applying rubber 82, the outer peripheral force-applying rubber 88, the front force-applying rubber 112, etc., can be integrally formed with each other, or they can be formed separately.

[0119] Furthermore, the guiding mechanism for inserting the connecting portions 54a and 54b of the second mounting member 22 along the connecting grooves 72a and 72b of the bracket 14 is not limited to a mechanism that guides the connecting portions 54a and 54b on both sides by means of the protrusions 92 and 102 provided on both sides of the connecting grooves 72a and 72b as described above. For example, the connecting portion 54a or 54b may be guided by means of the connecting groove 72a or connecting groove 72b on only one side. In addition, the guiding mechanism described above is not necessary in this invention. For example, such a sliding guiding mechanism may not be provided, and the connecting portion may be inserted into the connecting groove by passing over the protrusions that constitute the anti-disengagement engagement portion.

[0120] In addition, in the above embodiment, a liquid-sealed bracket body 12 is shown as the main body of the vibration damping device. However, for example, a solid vibration damping device main body without a liquid chamber, which is formed by elastically connecting the first mounting member and the second mounting member through a main body rubber elastomer, an active liquid-sealed vibration damping device main body that can obtain an active vibration damping effect based on the actuator, or a switchable liquid-sealed vibration damping device main body that can switch vibration damping characteristics, etc.

[0121] The specific structure of the bracket shown in the above embodiment is merely an example. As long as the connecting groove is provided, the mounting structure for mounting to the vehicle body, the presence or absence of the top plate and bottom plate, and the specific structure can be appropriately modified.
