However, conventional bracket-equipped tubular vibration-damping devices are individually designed for each attachment site and vehicle type, and there is no concept of standardization of parts. The shape and size of the lid and bracket often differ greatly depending on the location where the anti-vibration device is installed and the type of vehicle. For this reason, there was no concept of standardization of members and parts, and each part attached there was also designed separately so as to be compatible with each different rubber mount main body and bracket.

For example, in the case of a stopper member that constitutes a stopper mechanism that limits the amount of relative displacement of the power unit with respect to the vehicle body, the shape and size of the attached rubber mount body, or the shape and size of the bracket that abuts on it, are taken into consideration. Since it is necessary to consider the position, shape, size, etc. of the contact surface of the stopper mechanism, each anti-vibration device has been designed with a shape and size suitable for them.

By attaching the stopper member 62 to the first bracket 12 and the rubber mount main body 16 in a state of being positioned in the circumferential direction by the positioning mechanism 78, a part of the circumference of the peripheral wall portion 18 of the mounting hole 14 is left and right. The outer portion 66 of the stopper member 62 is positioned between the side portions 64, 64 facing each other in the direction, and the outer portion 66 of the stopper member 62 extends a part of the circumference of the peripheral wall portion 18 of the mounting hole 14 from the outer peripheral side in a predetermined direction. covering.

In the first motor mount 10 with bracket, the mating member 80 fixed to the inner shaft member 20 extends leftward in FIG. As a result, a portion of the circumference of the peripheral wall portion 18 of the mounting hole 14 faces a mating member 80 fixed to the inner shaft member 20 in the left-right direction with the projecting portion 76 of the stopper member 62 interposed therebetween. .

In the first bracketed motor mount 10 constructed as described above, a shocking large-amplitude vibration is input between the inner shaft member 20 and the outer cylindrical member 22 in the axial direction (vertical direction in FIG. 4). Then, the amount of axial relative displacement between the inner shaft member 20 and the outer cylindrical member 22 is limited by the axial stopper mechanism 82 .

That is, when the inner shaft member 20 is largely displaced in the vertical direction in FIG. abuts via the projecting portion 76 of the stopper member 62 . As a result, an axial stopper mechanism 82 is formed, and the amount of relative displacement between the inner shaft member 20 and the outer cylindrical member 22 in the axial direction is limited. Accordingly, in the first bracketed motor mount 10 , an axial stopper mechanism 82 is configured including the projecting portion 76 of the stopper member 62 . Further, in this embodiment, the entire stopper member 62 is made of an elastic material such as rubber, including the projecting portion 76 interposed between the striking surfaces of the first bracket 12 and the mating member 80. Therefore, it is possible to absorb the impact caused by the collision between the first bracket 12 and the mating member 80 . Note that the portion of the stopper member 62 interposed between the striking surfaces of the first bracket 12 and the mating member 80 and constituting the axial stopper mechanism 82 is not only the overhanging portion 76, but also the overhanging portion 76. It may also include a side portion 64 located closer to the mounting hole 68 side.

As a result, the second bracket 92 and the rubber mount main body 16 are assembled in a predetermined orientation, and each of the inner shaft members 20 is attached to the second bracket 92 arranged in the orientation shown in FIG. It is assembled so that the bolt hole 28 faces up and down. By assembling the stopper member 62 in a state of being positioned in the circumferential direction with respect to the second bracket 92 and the rubber mount body 16 by the positioning mechanism 78, the circumferential portion of the peripheral wall portion 18 of the mounting hole 14 is mounted. is located between the side portions 64, 64 facing each other in the left-right direction, and the outer portion 66 of the stopper member 62 extends a part of the circumference of the peripheral wall portion 18 of the mounting hole 14 to the outer circumference in a predetermined direction. covered from the sides.

In the second bracketed motor mount 90 constructed as described above, shocking large-amplitude vibration occurs between the inner shaft member 20 and the outer cylindrical member 22 in the direction perpendicular to the axis (horizontal direction in FIG. 10). When input, the amount of relative displacement between the inner shaft member 20 and the outer cylindrical member 22 in the direction perpendicular to the axis is limited by the first stopper mechanism 58 and the second stopper mechanism 60 perpendicular to the axis. Further, when a shocking large-amplitude vibration is input between the inner shaft member 20 and the outer tubular member 22 in the axial direction (vertical direction in FIG. 10), the shafts of the inner shaft member 20 and the outer tubular member 22 are displaced. The amount of relative directional displacement is limited by an axial stop mechanism 82 .

A third bracketed motor mount 100 is shown. The third bracket-equipped motor mount 100 has a cylindrical rubber mount body 16 that fits into the mounting hole 14 of the third bracket 102 in the same manner as the first and second bracket-equipped motor mounts 10 and 90 described above. It is assumed to be a mounted structure. In this embodiment, while the shape of the third bracket 102 is different from that of the first and second brackets 12, 92, the same rubber mount body 16 is used. In the third bracketed motor mount 100, the structure other than the third bracket 102 is the same as the first bracketed motor mount 10 described above, and the same members and components as the first bracketed motor mount 10 are used. Parts in the figure are given the same reference numerals as those in the first motor mount 10 with bracket, and detailed description thereof will be omitted. Although the orientation of the third motor mount with bracket 100 when mounted on a vehicle is not limited, in the following description, the vertical direction means the vertical direction in FIG. A direction and a left-right direction are directions perpendicular to the plane of FIG.

That is, in the third bracketed motor mount 100 as well, the rubber mount main body 16 is press-fitted into the mounting hole 14 of the third bracket 102, and the same stopper member 62 as in the first bracketed motor mount 10 is mounted. are assembled to the third bracket 102 and the rubber mount main body 16 as common parts. As a result, the third bracket 102 and the rubber mount main body 16 are assembled in a predetermined orientation, and each of the inner shaft members 20 is attached to the second bracket 92 arranged in the orientation shown in FIG. It is assembled so that the bolt hole 28 faces up and down. By assembling the stopper member 62 in a state of being positioned in the circumferential direction with respect to the third bracket 102 and the rubber mount body 16 by the positioning mechanism 78, the peripheral wall portion 18 of the mounting hole 14 is partially mounted on the circumference. is positioned between the side portions 64, 64 facing each other in the left-right direction, and the outer portion 66 of the stopper member 62 partially extends the circumference of the peripheral wall portion 18 of the mounting hole 14 forward from the outer peripheral side. covering.

The inner shaft member 20 is attached to the mating member 103 on the vehicle body side indicated by the two-dot chain line in FIGS. In the third bracketed motor mount 100, as also shown in FIG. 12, the mating member 103 fixed to the inner shaft member 20 faces forward (to the right in FIG. 12) where the outer portion 66 is located. , and extends downwardly in contact with the outer portion 66 . As a result, a portion of the circumference of the peripheral wall portion 18 of the mounting hole 14 is fixed to the inner shaft member 20 with a portion of the side portion 64 of the stopper member 62 (the portion colored gray in FIG. 12) sandwiched therebetween. It opposes the counterpart member 103 to be connected in the left-right direction. In addition, a portion of the circumference of the peripheral wall portion 18 of the mounting hole 14 opposes the mating member 103 fixed to the inner shaft member 20 with the outer portion 66 of the stopper member 62 interposed therebetween in the axis-perpendicular direction (front-rear direction). are doing.

In the third bracketed motor mount 100 constructed as described above, shocking large-amplitude vibration occurs between the inner shaft member 20 and the outer cylindrical member 22 in the direction perpendicular to the axis (horizontal direction in FIG. 13). When input, the amount of relative displacement between the inner shaft member 20 and the outer cylindrical member 22 in the direction perpendicular to the axis is limited by the first stopper mechanism 58 and the second stopper mechanism 60 perpendicular to the axis. Further, when a shocking large-amplitude vibration is input between the inner shaft member 20 and the outer cylindrical member 22 in the longitudinal direction (horizontal direction in FIG. 12), which is another direction perpendicular to the axis, the inner shaft member 20 and the outer cylindrical member 22 A third axis-perpendicular stopper mechanism 104 limits the amount of relative displacement with respect to the outer cylindrical member 22 in the axis-perpendicular direction. Furthermore, when a shocking large-amplitude vibration is input between the inner shaft member 20 and the outer tubular member 22 in the axial direction (vertical direction in FIG. 13), the shaft between the inner shaft member 20 and the outer tubular member 22 The amount of relative directional displacement is limited by an axial stop mechanism 106 .

That is, when the inner shaft member 20 is largely displaced to the right in FIG. abut through the outer portion 66 of the stopper member 62 . As a result, a third axis-perpendicular stopper mechanism 104 is formed, and the amount of relative displacement between the inner shaft member 20 and the outer cylindrical member 22 in the axial direction is limited. Accordingly, in the third bracketed motor mount 100, a third transverse stop mechanism 104, including the outer portion 66 of the stop member 62, is different from the first and second transverse stop mechanisms 58,60. Configured.

Further, when the inner shaft member 20 is largely displaced in the vertical direction in FIG. contact via the side portion 64 of the stopper member 62 (in particular, the portion colored in gray in FIG. 12). As a result, an axial stopper mechanism 106 is formed, and the amount of relative displacement between the inner shaft member 20 and the outer tubular member 22 in the axial direction is limited. Thus, in the third bracketed motor mount 100 , an axial stop mechanism 106 is provided, including the side portions 64 of the stop member 62 . In the third motor mount with bracket 100, when the mating member 103 fixed to the inner shaft member 20 is provided across not only the side portion 64 but also the projecting portion 76 when viewed in the left-right direction. The portion of the stopper member 62 interposed between the striking surfaces of the third bracket 102 and the mating member 103 and constituting the axial stopper mechanism 106 includes not only the side portion 64 but also the projecting portion 76. You can stay.

As described above, in the first to third bracketed motor mounts 10, 90, 100, the respective brackets (first to third brackets 12, 92, 102) have different shapes. Portions of the peripheral wall portion 18 of the mounting hole 14 located between the pair of side portions 64, 64 are substantially equal in axial direction (horizontal dimension). Specifically, the axial dimension of the peripheral wall portion 18 of the first bracket 12 indicated by A in FIG. 4, the axial dimension of the peripheral wall portion 18 of the second bracket 92 indicated by B in FIG. The axial dimension of the peripheral wall portion 18 of the third bracket 102 indicated by C in 13 is substantially equal.

According to the first to third bracket-equipped motor mounts 10, 90, 100, which are a plurality of types of bracket-equipped tubular vibration-damping devices of the present embodiment, each of the brackets (the first to third brackets 12, 92, 102) are different, but the same stopper member 62 is adopted as a common component, and the stopper member 62 is used to operate the axial stopper mechanisms 82, 106 of the motor mounts 10, 90, 100 with brackets. is configured. That is, the stopper member 62 has a groove shape, and can be mounted by being sandwiched between the brackets 12, 92, 102 so that the pair of side portions 64, 64 are positioned on both sides of the mounting hole 14 in the axial direction. . Therefore, the common stopper member 62 can be stably assembled regardless of the shape of the bracket. Further, in this embodiment, in the first and second bracketed motor mounts 10 and 90, the stopper mechanism 82 in the axial direction can be configured by the projecting portion 76 of the stopper member 62, and the In the motor mount 100, the lateral portions 64 of the stop member 62 may form an axial stop mechanism 106. As shown in FIG. Therefore, the lateral portion 64 and the projecting portion 76 of the stopper member 62 can be used to form the axial stopper mechanism required for each cylindrical vibration isolator (eg, motor mount).

In the third motor mount with bracket 100, the outer portion 66 of the stopper member 62 is used to provide a third axis-perpendicular stopper mechanism 104, which is one of the axis-perpendicular stopper mechanisms. As a result, the same stopper member 62 can be used to construct both the axial stopper mechanisms 82 and 106 and the axially perpendicular stopper mechanism (third axially perpendicular stopper mechanism 104). Can be applied to motor mounts with brackets. In particular, since the same stopper member 62 can be used to construct the axial stopper mechanisms 82 and 106 and the axially perpendicular stopper mechanism (third axially perpendicular stopper mechanism 104), the tubular vibration isolator with bracket can be used. A device (for example, a motor mount with a bracket) can be miniaturized.

The stopper member 62 and the rubber mount body 16 have a positioning mechanism 78 in the circumferential direction, and the brackets 12, 92, 102 and the rubber mount body 16 are also positioned in the circumferential direction by a conventionally known positioning mechanism. As a result, the side portion 64, the outer portion 66, and the projecting portion 76 of the stopper member 62 can be arranged at predetermined positions with respect to the brackets 12, 92, and 102, respectively.

The inner shaft member 20 has a fitting protrusion 30 protruding to the outer peripheral surface at the intermediate portion in the axial direction, and the stopper member 62 has an outer fitting protrusion 70 fitted onto the fitting protrusion 30 . . That is, when the stopper member 62 is assembled to the rubber mount main body 16 , the stopper member 62 is fixed to the rubber mount main body 16 by fitting the outer fitting protrusion 70 onto the fitting protrusion 30 . can be done. In particular, the fitting protrusion 30 and the outer fitting protrusion 70 (and the oblong portion 69a of the mounting hole 68 on the periphery thereof) are each formed in an oval shape, and the fitting protrusion 30 and the mounting hole 68 are formed in an oval shape. However, since it has the projecting portion 32 and the projecting portion 69b that correspond to each other, it is possible to configure a positioning mechanism 78 for the stopper member 62 and the rubber mount main body 16 in the circumferential direction.

In the portion of the stopper member 62 formed into a groove by the pair of side portions 64, 64 and the outer portion 66, the axial direction (horizontal direction) of the pair of side portions 64, 64 and the outer portion 66 The dimensions are assumed to be substantially constant. As a result, the shape of the stopper member 62 becomes relatively simple, which is advantageous in improving shape stability and avoiding deterioration in durability. In this embodiment, since the pair of side portions 64, 64 and the outer portion 66 each have a certain amount of dimension in the axial direction, these side portions 64 and the outer portion 66 are used to , an axial stopper mechanism or a perpendicular stopper mechanism can be easily provided.

The side portion 64 of the stopper member 62 is provided with an overhanging portion 76, and the outer peripheral edge shape of the overhanging portion 76 is curved in the circumferential direction and convexes outward. As a result, in the axial stopper mechanism 82 provided on the projecting portion 76, the projecting portion 76, the bracket (in the embodiment, the first bracket 12 or the second bracket 92) or the mating members 80, 94 The contact area is ensured, and stress distribution when the bracket and the mating member 80, 94 collide with each other through the projecting portion 76 is achieved. Also, the shape stability of the molded product in the stopper member 62 is improved.

In each bracket (first to third brackets 12, 92, 102), the axial dimensions (A, B, C, respectively) of the portion of the peripheral wall portion 18 of the mounting hole 14 to which the stopper member 62 is mounted are mutually are approximately equal. As a result, the same stopper member 62 can be mounted regardless of the overall shape of each bracket 12, 92, 102, thereby improving the degree of freedom in designing the shape of the bracket.

In this embodiment, the entire stopper member 62 is made of an elastic material such as rubber. The portion 76 is also made of an elastic material. As a result, the impact when the brackets 12, 92, 102 and the mating members 80, 94, 103 collide with each other through the side portion 64, the outer portion 66 and the projecting portion 76 is buffered. The side portion 64, the outer portion 66 and the projecting portion 76 can function as rubber cushions.

It may be fixed to the inner peripheral surface. That is, the method of attaching the rubber mount main body to the attachment hole in the bracket is not limited to press fitting. Also, the shape of the inner shaft member is not limited, and may be, for example, a columnar shape or a polygonal columnar shape. Furthermore, the inner shaft member may have a cylindrical shape or a polygonal cylindrical shape, and may be fixed to the mating member with a mounting bolt or the like inserted through the inner shaft member. The mating member to which the inner shaft member is fixed may be a member on the vehicle body side, or may be a member on the power unit side such as a motor.
