Description

  The present invention relates to a cylindrical vibration-proof mount including a rigid inner cylinder member, a rubber elastic body vulcanized and bonded to the outer peripheral surface of the inner cylinder member, and a rigid outer member that wraps the rubber elastic body from the outer peripheral side.

2. Description of the Related Art Conventionally, a cylindrical vibration-proof mount having a rigid inner cylinder member and an outer cylinder member and a rubber elastic body disposed therebetween has been widely used as an engine mount for an automobile.
FIG. 9 shows a specific example.

In the figure, reference numeral 200 denotes a metal rigid inner cylinder member, 202 denotes a metal rigid outer cylinder member, and 204 denotes a rubber elastic body disposed therebetween.
The rubber elastic body 204 is integrally fixed to the inner cylinder member 200 and the outer cylinder member 202 by vulcanization adhesion, and elastically couples the inner cylinder member 200 and the outer cylinder member 202.

The rubber elastic body 204 has a pair of elastic legs 206 that expand from the inner cylinder member 200 into a V shape and reach the outer cylinder member 202.
The ends of the pair of elastic legs 206 on the outer cylinder member 202 side are seating portions 208, which are seated on the inner peripheral surface of the outer cylinder member 202 and attached to the outer cylinder member 202 by vulcanization adhesion. It is fixed.
A gap S is formed between the rubber elastic body 204 and the outer cylinder member 202 on the upper side of the inner cylinder member 200.

  The cylindrical anti-vibration mount shown in FIG. 9 is axially pressed into the cylindrical press-fitting portion of the mounting bracket 210 shown in FIG. Are attached to the mounting bracket 210 and attached to the vehicle with the mounting bracket 210 in this state.

The reason why the outer cylinder member 202 is drawn in the reduced diameter direction is as follows.
That is, the rubber elastic body 204 contracts after vulcanization, and tensile strain remains on the adhesive interface with the outer cylinder member 202 due to the contraction.
Therefore, by drawing the outer cylinder member 202, preliminary compression is applied to the rubber elastic body 204 to eliminate residual distortion.

  However, in the case of the cylindrical vibration-proof mount shown in FIG. 9, the outer cylindrical member 202 is necessary together with the mounting bracket 210 and the like, and the number of parts for mounting the cylindrical vibration-proof mount as a whole is large, and press fitting into the mounting bracket 210 A process is required, and a large jig and a press machine are required at that time. In addition, the outer cylinder member 202 needs to be drawn, and the cost is increased as a whole.

  Further, even if such drawing processing is performed, it is not possible to sufficiently apply pre-compression to the rubber elastic body 204, and therefore it is not possible to sufficiently prevent the tensile force from acting on the rubber elastic body 204 during use. There is a problem, and if the amount of drawing is increased in order to increase the amount of pre-compression, film cracking of the adhesive is likely to occur, and in this case, the bonding reliability is impaired.

In addition, there is a problem that sufficient preliminary compression cannot be applied to the seating portion 208 at the end of the elastic leg 206.
The seat portion 208 is fixed to the outer cylinder member 202 and is firmly bound by the outer cylinder member 202. In this state, the inner cylinder member 200 is relatively close to the outer cylinder member 202. When it moves away or rotates, a tensile force acts on the seating portion 208 due to the elastic deformation of the elastic leg 206 accompanying this, and if the tensile force increases, the seating portion 208 cracks and its durable life This causes a problem of lowering.

  On the other hand, a rubber elastic body 204 is integrally vulcanized and molded on the inner cylinder member 200, and this is pressed into the outer cylinder member 202 in the axial direction to assemble them. It is disclosed in the following Patent Document 1.

  Here, when the rubber elastic body 204 is press-fitted into the outer cylinder member 202, a lubricant is applied in order to smoothly perform the press-fitting, but the lubricant is absorbed by the rubber elastic body 204, but the outer cylinder. Since the lubricant is not absorbed by the member 202 and therefore remains attached to the outer cylinder member 202, a process such as hot water washing or wiping to remove the lubricant is required as a post process, and after press-fitting However, there is a problem that requires such a troublesome post-process.

  Further, even in the case of assembly by such press-fitting, there is a problem that sufficient preliminary compression cannot be applied to the seating portion 208, and this is also the case in the cylindrical vibration-proof mount disclosed in Patent Document 1. There is a problem that a mounting bracket for mounting on a vehicle is required separately.

On the other hand, the following Patent Document 2, Patent Document 3, and Patent Document 4 disclose that a rigid outer member is constituted by a mounting bracket and is divided in a direction perpendicular to the axis.
However, none of those disclosed in these patent documents preliminarily compress a rubber elastic body, in particular, an elastic leg, and further, a seating portion at an end thereof, and does not solve the problem of the present invention. Is different.

Furthermore, if necessary, sufficient pre-compression can be easily applied to the elastic legs and seating parts, and there is no need for complicated post-processing for removing the lubricant after the construction of the cylindrical vibration-proof mount. In addition, when used as an engine mount, a cylindrical shape that can be used in common with a pre-assembled body of an inner cylinder member and a rubber elastic body for mounting brackets of different shapes and sizes for each engine The purpose is to provide an anti-vibration mount.

  Thus, according to the first aspect of the present invention, there is provided a rigid inner cylinder member, a rubber elastic body vulcanized and bonded to the outer peripheral surface of the inner cylinder member, and the rubber elastic body is wrapped from the outer peripheral side. A cylindrical vibration isolating mount including a rigid outer member having an outer cylindrical wall that is curved around the member, wherein the outer member is configured by a mounting bracket, and the circumferential direction of the curved outer cylindrical wall The rubber elastic body is compressed and compressed in the direction perpendicular to the axis, and the divided bodies are combined and integrated in the direction perpendicular to the axis.

  According to a second aspect of the present invention, in the first aspect, the rubber elastic body has a pair of elastic legs extending from the inner cylindrical member so as to expand in a V shape and reaching the outer member. The divided body is coupled in a state where the elastic legs are compressed in the extending direction.

  According to a third aspect of the present invention, there is provided a bearing according to the second aspect, wherein the rubber elastic body protrudes from the inner cylindrical member in a direction opposite to the elastic legs in addition to the pair of elastic legs and reaches the outer member. And the divided body is connected to the pair of elastic legs in a state of compressing the pair of elastic legs via the support portion while compressing the support portion toward the inner cylinder member.

  According to a sixth aspect of the present invention, in any one of the first to fifth aspects, the cylindrical vibration-proof mount is an engine mount or a vibration-proof mount for an exhaust system component.

Effects and effects of the invention

  As described above, according to the present invention, the outer member in the cylindrical vibration-proof mount is constituted by the mounting bracket, and the rubber elastic body is divided into a plurality of parts in a direction perpendicular to the axis at a predetermined position in the circumferential direction of the outer tube wall that is bent. Each divided body is combined and integrated so as to be compressed in a direction perpendicular to the axis. According to the present invention, since the mounting bracket forms the outer member, the outer cylinder member 202 shown in FIG. 9 is mounted. This is not necessary separately from the bracket, and the number of required parts can be reduced.

In addition, unlike the cylindrical vibration-proof mount shown in FIG. 9, the drawing process and the press-fitting process are not required, and further, it is not necessary to apply a lubricant for press-fitting the rubber elastic body. The step of removing the lubricant after the application and press-fitting is not required, and the number of necessary steps as a whole is small, and the cost can be reduced.
In addition, since drawing is not required, there is no problem that the drawing process causes a film crack of the adhesive and impairs the bonding reliability.

The present invention is characterized in that the outer member is divided into each divided body so that each divided body includes the curved portion of the outer cylinder wall. Further, a compressive force in the centripetal direction, that is, the direction toward the inner cylinder member can be applied to the rubber elastic body.
Further, by changing the shape and dimensions of the rubber elastic body before compression of the divided bodies before joining, the pre-compression amount can be variously changed and the desired compression amount can be obtained.

In the present invention, when the cylindrical vibration-proof mount is used as, for example, an engine mount, even when the shape, dimensions, etc. of the mounting bracket are different for each engine, the inner assembly of the inner cylindrical member and the rubber elastic body are attached to them. The entire cylindrical anti-vibration mount is not required to be configured and prepared for each engine.
Thereby, the cost of the cylindrical vibration-proof mount for every engine can be reduced effectively.

  According to a second aspect of the present invention, the rubber elastic body has a pair of elastic legs extending from the inner cylinder member into a V shape and extending to the outer member, and the pair of elastic legs is compressed in the extending direction. According to the second aspect of the present invention, sufficient preliminary compression can be applied to the pair of elastic legs simply by connecting the divided bodies, thereby improving durability. It can be made good.

According to a third aspect of the present invention, in addition to the pair of elastic legs, the rubber elastic body is provided with a support portion that protrudes from the inner cylindrical member in the direction opposite to the elastic leg and reaches the outer member, and is connected by dividing the divided body. The support portion is compressed toward the inner cylindrical member side, and the pair of elastic legs is compressed via the support portion. The support portion is provided to compress the pair of elastic legs. By doing so, it becomes possible to pre-compress the pair of elastic legs more efficiently and in the required amount as the divided bodies are joined.
In addition, the support portion can also function as a displacement restricting portion that restricts an excessive displacement of the inner tubular member relative to the outer member when the tubular vibration-proof mount is used.

Next, according to a fourth aspect of the present invention, a seating portion that sits for a predetermined circumferential length along the inner peripheral surface of the outer member is provided at the end portions of the pair of elastic legs, and the seating portion is sandwiched in the circumferential direction by joining the divided bodies and compressed. Therefore, according to the fourth aspect, partial compression can be easily applied to the seating portion only by connecting and assembling the divided bodies.
Thus, by applying sufficient precompression to the seating portion in this way, even when the inner cylinder member approaches, moves away from, or rotates in the direction away from the outer member during use, the rubber elasticity It is possible to satisfactorily avoid the application of a tensile force to the seating part as the body deforms, and it is possible to solve the problem of causing a crack in the seating part and further reducing the durability life due to the cracking.

In this case, one of the divided bodies and any of the other divided bodies are in contact with one end and the other end in the circumferential direction of the seating portion at the time of coupling, and the seating portions are reversely directed toward each other in the circumferential direction. The restraint part which presses and compresses can be provided (Claim 5).
By doing so, the seating portion can be firmly restrained and held by the divided body after assembly, that is, after the divided bodies are joined.
In addition, a predetermined amount of preliminary compression can be easily applied when the divided bodies are joined.

  The present invention can be applied to vibration-proof mounts for various uses, and is particularly suitable for application to vibration-proof mounts for engine mounts or exhaust system parts (claim 6).

Next, an embodiment in which the present invention is applied to a cylindrical vibration-proof mount used for an engine mount will be described in detail with reference to the drawings.
1 to 4, reference numeral 10 denotes a cylindrical vibration-proof mount according to this embodiment, which includes a pair of mounting brackets 14, 16 constituting a rigid inner cylindrical member 12, a rigid outer member such as iron or aluminum, and the like. It has a rubber elastic body 18 disposed between them and vulcanized and bonded to the outer peripheral surface of the inner cylinder member 12.

Reference numeral 20 denotes an outer cylinder wall constituted by the pair of mounting brackets 14 and 16, which is entirely bent around the inner cylinder member 12, and the rubber elastic body 18 is accommodated in the inside together with the inner cylinder member 12. Has been.
Here, the mounting brackets 14 and 16 form a split body (two split bodies) in the outer member.

As shown in FIGS. 2 and 4, one mounting bracket 14 is formed by press-bending a single iron plate material or molding an aluminum material, and the outer cylindrical wall 20 is formed at the center in the longitudinal direction. An upper portion 20A is formed. Moreover, the flat part 22 is formed in the both sides.
Most of the pair of flat portions 22 is a fixing portion 24 for coupling with the other mounting bracket 16, and a fixing hole 26 is formed there.

The other mounting bracket 16 is also formed by press bending a single iron plate material, and a lower portion 20B of the outer cylindrical wall 20 is formed at the center in the longitudinal direction. In addition, both side portions are flat portions 22.
The entire pair of flat portions 22 is a fixing portion 24, and a fixing hole 26 is formed in the fixing portion 24.
The pair of mounting brackets 14 and 16 are coupled to each other by inserting a bolt 30 with a serration 28 into the fixing hole 26 and caulking with the fixing portions 24 overlapped.

The pair of flat portions 22 in one mounting bracket 14 extends inward longer than the pair of flat portions 22 in the other mounting bracket 16 by a predetermined dimension, and the extending portions are described later in the rubber elastic body 18. The restraining portion 32 is configured to abut against and restrain one end of the seating portion 46 in the circumferential direction.
The other mounting bracket 16 is provided with an upward bulging portion 34 in the lower portion 20B of the outer cylindrical wall 20 in the figure, and the right and left inclined portions of the bulging portion 34 are arranged in the circumferential direction of the seating portion 46. It is set as the restraining part 36 which contacts and restrains the other end.
In addition, between the outer cylindrical wall 20 and the rubber elastic body 18 inside the pair of mounting brackets 14 and 16, there are three edge portions (void portions) 38, 38 and 40 in the circumferential direction. Is formed.

  As shown in FIG. 6, the rubber elastic body 18 has a pair of elastic legs 42 that extend from the inner cylinder member 12 in a V shape and reach the outer cylinder wall 20. As shown in FIG. 5, a support portion 44 that protrudes from the inner cylinder member 12 in a direction opposite to the elastic legs 42 and reaches the outer cylinder wall 20 is provided.

Each of the pair of elastic legs 42 has a base-like seating portion 46 at the end on the outer cylindrical wall 20 side.
Here, as shown in FIG. 2, the seating portion 46 has a shape that is entirely curved along the outer cylindrical wall 20, specifically, the inner peripheral surface of the lower portion 20B.

  Further, as shown in FIG. 2, these seat portions 46 are larger in the axial and circumferential dimensions than the main body portion of the elastic leg 42, and the seat portions 46 are outside the wide area. The cylindrical wall 20 is seated in close contact with the inner peripheral surface of the lower portion 20B.

In the present embodiment, the rubber elastic body 18 has a pair of mounting brackets 14 and 16 overlapped with each other and coupled with a bolt 30 in the direction indicated by arrows P _{1 to} P ₇ in FIG. 4 with respect to the rubber elastic body 18. The pressing force works. The shape and size of each part in the rubber elastic body 18 are determined in advance as such.
Specifically, the length of the pair of elastic legs 42 before assembly, the protruding height of the support portion 44, the circumferential length of the seat portion 46, and the like are determined in advance.

As a result, when coupled with superposed mounting brackets 14 and 16, bearing 44 in the rubber elastic body 18 is compressed in the arrow P ₁ direction diagram (preliminary compression), also in a pair of resilient legs 42 arrows Compressed in the P ₃ and P ₆ directions.

At this time, if the supporting portion 44 is not provided, even if a pressing force is applied to the pair of elastic legs 42 in the directions of the arrows P ₃ and P ₆ , the elastic legs are merely raised by the inner cylindrical member 12. 42 is not compressed. However, in the present embodiment, the support portion 44 is in a state of being in contact with the upper portion 20A of the outer cylindrical wall 20 and receives a force there. The pair of elastic legs 42 are effectively compressed in the directions of arrows P ₃ and P _{6 in the} drawing together with the support portion 44 because the pressing force is applied in the direction.
That is, the pair of elastic legs 42 is compressed in the extending direction, and the support portion 44 is compressed in the protruding direction.

On the other hand, when the pair of mounting brackets 14 and 16 are joined together, the seating portion 46 at the end of the pair of elastic legs 42 has one end in the circumferential direction, specifically, the upper end in the figure is the restraining portion 32 of the mounting bracket 14. Is pressed and compressed in the directions of arrows P ₂ and P ₇ .
Further, the other end in the circumferential direction, specifically, the lower end in the figure is pressed and compressed in the directions of arrows P ₄ and P _{5 in the} figure by the inclined restricting portion 36 of the mounting bracket 16.

As a result, the pair of seating portions 46 are also assembled to the pair of mounting brackets 14 and 16 in a state of being sandwiched and compressed by the pair of mounting brackets 14 and 16 in the circumferential direction.
After the assembly, the seating portion 46 is firmly restrained and held between the restraining portions 32 and 36 by the restraining action of the restraining portions 32 and 36.
In other words, in the present embodiment, the seat portion 46 itself is partially compressed in the circumferential direction by the mounting brackets 14 and 16 and is restrained and held in the compressed state.

Next, FIG. 7 shows another embodiment of the present invention. Here, instead of the mounting bracket 14 described above, an aluminum mounting bracket 48 is used.
Here, the mounting bracket 48 has a block shape, and the portion along the straight portion 38 constitutes the upper portion 20 </ b> A of the outer cylinder wall 20.
In FIG. 7, reference numeral 50 denotes a mounting hole provided in an aluminum mounting bracket 48.

FIG. 8 shows still another embodiment of the present invention. Here, an example in which the cylindrical vibration-proof mount 10 is attached to a vehicle using an iron mounting bracket 52 together with the mounting bracket 16 is shown. .
In this embodiment, the mounting bracket 16 is formed with a downward bent portion 54 in the drawing.
In FIG. 8, reference numeral 56 denotes an iron mounting bracket 52, and 58 denotes a mounting hole provided in the mounting bracket 16.

  According to the cylindrical vibration-proof mount 10 of the present embodiment as described above, since the mounting brackets 14 (or 48, 52) and 16 form the outer member, the outer cylindrical member 202 shown in FIG. 9 is mounted. This is not necessary separately from the brackets 14 and 16, and the number of required parts can be reduced.

In addition, unlike the cylindrical vibration-proof mount shown in FIG. 9, the drawing process and the press-fitting process are not required, and further, it is not necessary to apply a lubricant for press-fitting the rubber elastic body. The step of removing the lubricant after the application and press-fitting is not required, the number of required steps as a whole is small, and the required cost can be reduced.
In addition, since drawing is not required, there is no problem that the drawing process causes a film crack of the adhesive and impairs the bonding reliability.

Moreover, in this embodiment, since the mounting brackets 14 and 16 as the respective divided bodies form a divided body including the curved portion of the outer cylindrical wall 20, the rubber elastic body 18 is joined when the mounting brackets 14 and 16 are coupled. On the other hand, a compressive force in the centripetal direction, that is, the direction toward the inner cylinder member 12 can be applied.
Further, by changing the shape and size of the rubber elastic body 18 before the mounting brackets 14 and 16 are joined, the preliminary compression amount can be variously changed and the desired compression amount can be obtained.

In the present embodiment, even when the shapes, dimensions, and the like of the mounting brackets 14 and 16 are different for each engine, the pre-assembled body of the inner cylinder member 12 and the rubber elastic body 18 can be commonly used for them. It is not necessary to prepare and prepare the entire cylindrical vibration-proof mount 10 exclusively for each engine.
Thereby, the cost of the cylindrical vibration-proof mount 10 for every engine can be reduced effectively.

  In the present embodiment, the rubber elastic body 18 has a pair of elastic legs 42, and the mounting brackets 14 and 16 are coupled in a state in which the pair of elastic legs 42 are compressed in the extending direction. Sufficient preliminary compression can be applied to the pair of elastic legs 42 simply by connecting the mounting brackets 14 and 16, and the durability can be improved.

In addition, in the present embodiment, the rubber elastic body 18 is provided with a support portion 44 that protrudes from the inner cylinder member 12 in the direction opposite to the elastic leg 42 and reaches the outer cylinder wall 20. Since the support portion 44 is compressed toward the inner cylinder member 12 and the pair of elastic legs 42 is compressed via the support portion 44, the mounting brackets 14 and 16 are automatically connected. Therefore, the pair of elastic legs 42 can be pre-compressed in an amount that is accurately determined.
The support portion 44 also functions as a displacement restricting portion that restricts a relative excessive displacement of the inner cylinder member 12 relative to the outer cylinder wall 20 when the cylindrical vibration-proof mount 10 is used.

In the present embodiment, since the seating portion 46 is sandwiched and compressed in the circumferential direction by the coupling of the mounting brackets 14 and 16, the seating is simply performed by coupling the mounting brackets 14 and 16 and assembling the rubber elastic body 18. Partial compression can be easily applied to the portion 46.
Thus, by applying sufficient preliminary compression to the seating portion 46 in this way, when the inner cylinder member 12 approaches the outer cylinder wall 20 and is relatively displaced or rotationally displaced in use during use. However, it is possible to satisfactorily avoid the tensile force acting on the seating portion 46 with the deformation of the rubber elastic body 18, causing a crack in the seating portion 46, and further reducing the durability life due to the crack. Solvable.

Further, in this embodiment, the mounting brackets 14 and 16 are brought into contact with one end and the other end in the circumferential direction of the seating portion 46 when they are coupled, and the seating portion 46 is pressed in a reverse direction to approach each other in the circumferential direction and compressed. Since the restraining portions 32 and 36 are provided, the seating portion 46 can be firmly restrained and held by the mounting brackets 14 and 16 after assembly, that is, after the mounting brackets 14 and 16 are joined.
In addition, when the mounting brackets 14 and 16 are coupled, a predetermined amount of preliminary compression can be easily applied.

  Although the embodiment of the present invention has been described in detail above, this is merely an example, and the present invention can divide the outer member (outer cylinder wall 20) into three parts or more, and can also be used as an engine mount. The present invention can be applied as an anti-vibration mount for exhaust system parts other than the above, or can be applied as other anti-vibration mounts, and the present invention has been variously modified without departing from the gist thereof. It can be configured in the form.
