Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an anti-vibration support device suitable for anti-vibration support of a suspension mechanism of an automobile.

[0002]

2. Description of the Related Art An anti-vibration support device used for a suspension mechanism of an automobile is designed to improve the responsiveness to an impact applied to the automobile to improve the steering stability and riding comfort of the automobile.
It is required to make the spring constant in the direction perpendicular to the axis hard and the torsion spring constant soft and to reduce the hysteresis in the relationship between the torsion angle and the torsion moment. Further, this vibration isolating support device is subjected to a large load, unlike a vibration isolating support device for supporting an engine mount or the like, so it is necessary to enhance durability in the direction perpendicular to the axis.

Conventionally, this type of anti-vibration support device includes, for example, an inner tubular metal fitting, an outer tubular metal fitting, and a rubber layer which is filled between the two and is bonded to the outer surface of the inner tubular metal fitting and the inner surface of the outer tubular metal fitting. It is known that a so-called inner-outer tube adhesive type bush provided with the above is used, the diameter of which is reduced and press-fitted into the tubular collar portion of the link member. Further, as another vibration-proof support device, a so-called press-fit type vibration-proof support device in which rubber is bonded to the inner tubular metal fitting is press-fitted into the tubular collar portion, or rubber which is bonded to the inner tubular metal fitting. There is known a so-called pinching type anti-vibration supporting device in which the rubber layer is fixed while being compressed and contracted by being sandwiched by the tubular half-divided collar portion.

[0004]

By the way, in the anti-vibration supporting device using the above-mentioned inner-outer tube adhesive type bush, since the inner-outer tube fitting and the rubber are adhered, the spring constant in the direction perpendicular to the axis is hard and the torsion spring constant is large. Is excellent in terms of characteristics such as softness and small hysteresis, and has the advantage of excellent durability in the direction perpendicular to the axis. However, this anti-vibration support device requires a long manufacturing process such as cleaning of the inner and outer cylindrical metal fittings, bonding treatment of the inner and outer cylindrical metal fittings, rubber vulcanization molding, press-fitting of the bush into the collar portion, etc. There is a problem.

On the other hand, the press-fitting type and the sandwiching type anti-vibration supporting devices are manufactured because the manufacturing process such as cleaning and adhering only the inner tubular metal member, rubber vulcanization molding, press-fitting to the collar portion of the bush is simple. The cost is low. However, this type of anti-vibration support device is a type in which rubber is compressed and fixed by the collar part, so the compression ratio of rubber is large, and therefore the spring constant in the direction perpendicular to the axis becomes softer and the hysteresis becomes larger. However, there is a characteristic problem that the responsiveness to the impact applied to is deteriorated. Further, since the rubber has a high compressibility, there is also a problem that the durability of the anti-vibration support device in the direction perpendicular to the axis is poor. The present invention is intended to solve the above problems, and an object thereof is to provide an anti-vibration support device having excellent properties such as a spring constant, excellent durability, and inexpensive.

[0006]

In order to achieve the above object, the structural feature of the invention according to claim 1 is that an elongated arm portion and at least one end of the arm portion are provided.
A part of the peripheral wall has a cylindrical part having a gap removed in the axial direction, and a pair of plate-shaped clamping parts extending substantially in parallel from both ends of the clearance position of the cylindrical part, and the tip of one clamping part. Is integrally connected to the arm portion, and the other end of the sandwiching portion is integrally connected to a fixed plate portion arranged substantially parallel to the arm portion, and a link member, and an outer periphery. The inner cylindrical metal member whose surface is bonded, the cylindrical rubber layer vulcanized and bonded around the inner cylindrical metal member, and the protruding rubber layer integrally provided on a part of the outer periphery of the cylindrical rubber layer. The tubular rubber layer and the protruding rubber layer of the bush member are inserted in accordance with the tubular portion and the sandwiching portion of the link member, and the fixing plate portion is provided on the surface of the facing arm portion. It is fixed in the crimped state and then compressed and fixed to the collar portion.

The structural feature of the invention according to claim 2 is that in the vibration-damping support device according to claim 1,
The compression ratio of the protruding rubber layer compressed by the pair of sandwiching parts is
This is because the compression ratio was made larger than that of the tubular rubber layer compressed by the tubular portion.

Further, the structural feature of the invention according to claim 3 is that in the vibration-damping support device according to claim 1,
A second gap is provided in the link member at a position opposite to the radial direction of the gap of the tubular portion, and a pair of plate-shaped first and second plate-shaped members extending in parallel in the radial direction from both ends of the second gap position of the tubular portion are provided. 2 clamping portions and a pair of second fixing plate portions attached to the tips of the second clamping portions are provided, and the bushing member is integrally provided with a second protruding rubber layer at a position opposite to the protruding rubber layer in the radial direction, and a second protruding The rubber layer
It is inserted between the pair of second sandwiching portions, and is compressed and fixed by the pair of second sandwiching portions as the pair of second fixing plate portions are fixed to each other in a crimped state.

The structural feature of the invention according to claim 4 is that in the vibration isolating support device according to claim 3,
The compression rate of the protruding rubber layer compressed by the pair of sandwiching portions and the compression rate of the second protruding rubber layer compressed by the pair of second sandwiching portions are larger than the compression rate of the tubular rubber layer compressed by the tubular portion. There is something I did.

[0010]

In the invention according to claim 1 configured as described above, the tubular rubber layer is not bonded to the tubular portion of the collar portion, but is fixed to the tip of the holding portion. By fixing the plate portion to the arm portion in a crimped state, the protruding rubber layer is firmly sandwiched by the sandwiching portion and firmly fixed to the collar portion, and both rubber layers are firmly fixed to the collar portion as a whole. Furthermore, since the tubular rubber layer is compressed by the tubular portion and the diameter thereof is reduced by pressing the fixing plate portion to the arm portion, the joint strength between the tubular portion and the tubular rubber layer is enhanced.

As a result, the spring constant, the torsion spring constant, and the hysteresis characteristic of the vibration isolating support device in the direction perpendicular to the axis can be made to be as good values as those of the vibration isolating support device of the inner-outer tube adhesive type. Further, since the joint strength of the bush member to the collar can be secured by compressing and fixing the protruding rubber layer, the compression rate of the tubular rubber layer itself can be set smaller than that of the press-fitting type vibration isolation support device. The durability of the anti-vibration support device in the direction perpendicular to the axis can be made comparable to the durability of the anti-vibration support device of the inner-outer tube adhesion type. Moreover, this vibration-isolating support device requires only inner tube adhesion compared to the inner-outer tube type anti-vibration support device, and the manufacturing process is simplified. It can be cheaper. Further, since this vibration isolating support device does not require an outer tubular metal fitting, the material cost can be reduced as compared with the inner and outer tubular type vibration isolating support device.

Further, in the invention according to claim 2 configured as described above, the strength of the joint with the protruding rubber layer by the sandwiching portion is further strengthened, and the compressibility of the tubular portion and the tubular rubber layer is further enhanced. By increasing the size, the joint strength of the bush member to the collar portion can be secured, and the joint strength between the tubular portion and the tubular rubber layer can be relaxed to be smaller than the compressibility of the tubular rubber layer. As a result, by reducing the compression rate of the tubular rubber layer, the state of the tubular rubber layer can be brought closer to that of the inner-outer tube adhesive type vibration isolation support device, and the characteristics and durability of the vibration isolation support device are improved. It can be approximated to a tube-bonding type anti-vibration support device.

Further, in the invention according to claim 3 configured as described above, the cylindrical rubber layer is not adhered to the cylindrical portion of the collar portion, but the protruding rubber layer is sandwiched between the sandwiching portion and the arm portion. The second protruding rubber layer is sandwiched between the second sandwiching portions, the fixing plate portion is fixed to the arm portion in a crimped state, and the second
The fixing plate parts are fixed in a crimped state. Therefore, the protruding rubber layer and the second protruding rubber layer are firmly sandwiched by the arm portion, the sandwiching portion, and the pair of second sandwiching portions, and are firmly fixed to the collar portion, so that the cylindrical rubber layer, the protruding rubber layer, and the second rubber layer Two
The protruding rubber layer is firmly fixed to the collar portion as a whole.
Further, since the fixing plate portion is fixed to the arm portion in the crimping state and the second fixing plate portions are fixed in the crimping state, the tubular rubber layer is also compressed and the diameter thereof is reduced. The bonding strength with the rubber layer is increased. As a result, in the link device, since the bush member is more strongly fixed to the link member as compared with the invention according to claim 1, the spring constant in the direction perpendicular to the axis and the torsion are further increased than in the link device according to claim 1. The spring constant and the hysteresis characteristic can be improved, and the durability of the link device in the direction perpendicular to the axis can be improved as well. The link device is provided at a low cost, like the link device according to claim 1.

Further, in the invention according to claim 4 configured as described above, the joining strength between the arm portion and the protruding rubber layer by the holding portion and the joining between the second protruding rubber layer by the pair of second holding portions are performed. The strength is further increased and the joint strength between the tubular portion and the tubular rubber layer is relaxed to be smaller than the compressibility of the tubular rubber layer. As a result, the state of the tubular rubber layer can be made closer to that of the inner / outer tube adhesive type vibration isolation support device, and the characteristics and durability of the vibration isolation support device can be approximated to those of the inner / outer tube adhesive type vibration isolation support device. it can.

In this embodiment, both collars 13 have the same structure, so only one of them will be described. The collar portion 13 is provided with a cylindrical portion 13a, and the cylindrical portion 13a is provided with a narrow gap 13a1 in the axial direction.

Holding plates 14a and 14b are attached in parallel to each other at both ends of the cylindrical portion 13a at the position of the gap 13a1. The sandwiching plates 14a and 14b have a trapezoidal shape that is narrower toward the outside, and the outer ends of the sandwiching plates 14a and 14b are closer to each other by about 30.

As shown in FIG. 3, the rubber bush member 20 is provided with an iron inner cylinder metal fitting 21 at the center position.
A rubber layer 22 having a substantially cylindrical shape is coaxially vulcanized and adhered to the periphery thereof. The rubber layer 22 is provided with ring-shaped groove portions 22b near both ends in the axial direction of the intermediate portion 22a, and at both ends thereof, retaining portions 22c having a larger diameter than the intermediate portion 22a. The outer diameter of the intermediate portion 22a is the cylindrical portion 13 of the collar portion 13.
It is almost the same as the inner diameter of a. And the intermediate portion 22a
The peripheral rubber wall is provided with a protruding rubber layer 23 which is slightly shorter than the intermediate portion 22a in the axial direction. The width of the protruding rubber layer 23 is larger than the distance between the sandwiching plates 14a and 14b. The rubber bush member 20 is molded by setting an inner cylinder metal fitting 21 whose outer peripheral surface is adhered to a molding die (not shown),
It is performed by injecting rubber and vulcanizing and adhering.

As shown in FIG. 4, the rubber layer 22 of the rubber bush member 20 is press-fitted into both the cylindrical portions 13a of the collar portion 13 of the link member 11 and the protruding rubber layer 23 is press-fitted between the sandwiching plates 14a and 14b.

The link device 10 is obtained by compressing the link member 11 of this assembly, pressing the fixing plate portion 15 against the arm portion 12 and crimping them, and then welding and fixing both by arc welding, spot welding or the like. Here, since the thickness of the protruding rubber layer 23 is smaller than the thickness of the rubber layer 22 in the radial direction, the compression rate of the protruding rubber layer 23 due to the pressure fixing is larger than the compression rate of the rubber layer 22.

By being fixed in a crimped state, the protruding rubber layer 23 is firmly sandwiched and fixed by the sandwiching plates 14a and 14b. Therefore, the rubber bush member 20 is firmly fixed to the collar portion 13 as a whole. Furthermore, since the rubber layer 22 is also compressed by the diameter reduction of the cylindrical portion 13a, the joint strength between the cylindrical portion 13a and the rubber layer 22 is increased. However, the compression rate of the rubber layer 22 is smaller than that of the protruding rubber layer 23, and it is easy to suppress the compression rate to several percent to 10%. Therefore, the state of the rubber layer 22 is better than that of the press-fit type collar portion. And is similar to the inner / outer tube adhesive type collar portion.

Further, the durability of the link device 10 in the direction perpendicular to the axis can be made comparable to the durability of the link device of the inner-outer tube bonding type. In addition, the link device 10 needs only the inner tube to be bonded as compared with the inner / outer tube bonding type link device, and the manufacturing process is simplified. Therefore, the manufacturing cost can be made lower than that of the inner / outer tube type link device. You can Further, since this link device does not require an outer cylinder fitting, the material cost can be reduced as compared with the link device of the inner / outer cylinder mounting type.
