Abstract

(57) [Abstract] [Purpose] The number of parts of the annular vibration proof mount 6 mounted on the inner peripheral edge portion 23 of the mounting hole 22 formed in the bracket 21 is reduced from the conventional six points. [Structure] An elastic body 7 made of a rubber-like elastic material, which has an annular shape and has an annular engagement groove 8 for engaging with an inner peripheral edge portion 23 on its outer peripheral surface, and is connected to the inner peripheral side of the elastic body 7. The vibration-proof mount 6 is composed of the annular rigid member 9 and the number of parts is two. Further, the rigid member 9 is divided into a first divided body 9a having a substantially L-shaped half-cut cross section and a second divided body 9b having a substantially half-cut half-cut cross section, and the number of parts is set to three.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an anti-vibration mount.

[0002]

[Prior Art]

 The propeller shaft of an automobile drive system is rotatably and elastically supported by a center bearing support 11 as shown in FIG. 3, and this center bearing support 11 has a bracket 21 and a plurality of anti-vibration mounts 1 therebetween. Is attached to the vehicle body. As shown in the enlarged view of FIG. 4, the vibration-proof mount 1 is formed in an annular shape so that it can be attached to the inner peripheral edge portion 23 of the attachment hole 22 provided in the bracket 21, that is, it has an annular shape. An outer peripheral side rigid member 2 having an annular engaging groove 3 for engaging the inner peripheral edge portion 23 on the outer peripheral surface, and an annular rubber-like elastic material connected to the inner peripheral side of the outer peripheral side rigid member 2. It has an elastic body 4 made of, and a ring-shaped inner peripheral side rigid member 5 connected to the inner peripheral side of the elastic body 4. The rigid member 2 on the outer peripheral side, the elastic body 4, and the rigid member 5 on the inner peripheral side are each divided into two divided bodies. The opening shape of the mounting hole 22 is circular as shown in FIG.

[0003]

[Problems to be solved by the device]

 The above-mentioned conventional technique has a problem that the number of parts is large, and accordingly, the manufacturing cost is high and the weight is heavy. The number of parts of the above-mentioned vibration proof mount is six, counting each divided body.

[0004]

[Means for Solving the Problems]

 In view of the above points, the present invention has been devised in order to solve the problems found in the above-mentioned prior art, and in order to achieve this object, it is provided in a bracket as described in claim 1. A ring-shaped vibration-damping mount to be mounted on the inner peripheral edge of the mounting hole, which is made of rubber and has an annular shape and an annular engaging groove on the outer peripheral surface that engages with the inner peripheral edge. A vibration-damping mount comprising a body and an annular rigid member connected to the inner peripheral side of the elastic body. As described in claim 2, the rigid member may be composed of a first divided body having a substantially L-shaped cut cross section and a second divided body having a substantially half-cut cross section.

[0005]

[Action]

 In the vibration-proof mount according to claim 1, the elastic body and the rigid member are each a single component, and in the vibration-proof mount according to claim 2, the elastic body is the single component and the rigid member is the first and second members. It is a two-part structure composed of divided bodies, and in any case, the number of parts can be reduced as compared with the conventional technology.

[0006]

【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings.

As shown in FIG. 1, the vibration-proof mount 6 is configured in an annular shape so as to be mounted on the inner peripheral edge portion 23 of the circular mounting hole 22 provided in the bracket 21, that is, Then, an elastic body 7 made of a rubber-like elastic material, which has an annular shape and is provided with an annular engaging groove 8 for engaging with the inner peripheral edge portion on the outer peripheral surface thereof, is connected to the inner peripheral side of the elastic body 7. The rigid member 9 is composed of a ring-shaped rigid member 9, and the rigid member 9 is composed of a first divided body 9a having a substantially L-shaped half cut section and a second divided body 9b having a substantially half-cut cross section. (Example of claim 2). The second divided body 9b can be omitted (embodiment of claim 1). However, according to this structure, the number of parts of the antivibration mount 6 is three or two, and in any case, the number of parts can be reduced as compared with the prior art, and accordingly, the manufacturing is possible. The cost can be reduced and the weight can be reduced. In order to facilitate the mounting of the elastic body 7 which is a single annular component, the mounting hole 22 may be provided with a notch 24 reaching the outer edge of the bracket 21, as shown in FIG.

[0008]

[Effect of the device]

 The present invention has the following effects. That is, the anti-vibration mount according to claim 1 is composed of two parts, and the anti-vibration mount according to claim 2 is composed of three parts. In any case, the number of parts can be reduced as compared with the conventional technique. Accordingly, the manufacturing cost can be reduced and the weight can be reduced.
