Abstract

PROBLEM TO BE SOLVED: To improve the damping characteristic and the temperature dependency by comprising a base member of which the vertical both ends are connected to a muffler and a frame, and having a penetration part on its central part, and mounting a damping member made of silicone rubber of high damping characteristic in the penetration part. SOLUTION: A vibration control rubber member 10 is formed by fitting and fixing a damping member 30 to a panetration part 21 of a base member 20 having the penetration part 21 on its central part. The vertical both sides of the penetration part 21 of the base member 20 are provided with the projections projecting in the central direction, and the connection holes 23 for respectively connecting the same to a muffler and a frame are formed on the projections. As the damping member 30, silicone rubber for isolating vibration such as high damping silicone rubber and the like is preferably used. According to this structure, the vibration is inhibited by the base member 20 and the damping member 30 at a low tempearture, and the damping effect of the base member 20 is impaired, but the vibration is inhibited by the damping member 30 at a high temperature. Accordingly the damping characteristic can be improved and the temperature dependency can be properly kept.

[0004] In response to such a demand, it has been considered to improve the damping property by changing the material of the vibration-proof rubber member. However, materials with good damping properties, for example,
When a material such as isobutylene / isoprene rubber (IIR) is used, it cannot be used as a silencer mount having severe temperature conditions because of its poor temperature dependency. It is also conceivable to use a material having good temperature dependency, for example, a high-damping silicone, but in this case, there is a problem that the strength becomes insufficient. Furthermore, damping can be imparted by a high filling compound such as carbon or oil, but the damping effect cannot be sufficiently obtained due to the environmental temperature. There is a problem of insufficient.

As shown in Table 3, the product characteristics of each example were slightly inferior to those of Comparative Example 1 in the value of Kd / Ks, but in all examples, the value of tan δ was clearly improved. You can see that it is. In addition, it can be seen that tan δ does not decrease even at a high temperature, and the temperature dependency is excellent. That is, it can be seen that the vibration-damping rubber member of the present invention has improved damping properties as compared with the conventional vibration-damping rubber member, and has good temperature dependency.
