- the vibration isolator according to the present invention includes: a mounting bracket connected to one of the vibration generating unit and the vibration receiving unit; an outer cylinder member connected to the other of the vibration receiving unit and the vibration generating unit; and a rubber elastic body.
- the rubber elastic body has a damping function and an insulating function against vibration input due to the vibration damping effect. It absorbs vibrations and prevents them from being transmitted to the vehicle body. Therefore, the vibration damping device of the present invention exhibits the same performance as a conventional vibration damping device when a vibration is input when a load is applied.
- the outer cylinder member is made of resin.
- the outer metal fittings which were conventionally made of metal, are made of resin to reduce costs and reduce weight.
- the rubber elastic body cannot be vulcanized and bonded to the resin outer metal fitting, the rubber elastic body is vulcanized and bonded between the metal mounting metal and the insert metal, and the insert metal is attached to the outer cylindrical member.
- the rubber elastic body is attached to the outer cylindrical member via an insert fitting by arranging the rubber elastic body along the inner peripheral surface of the outer cylindrical member. In this case, if the resin shrinks during the resin molding of the outer cylinder member, a gap is formed between the outer cylinder member and the insert fitting, and this gap may generate noise or the like.
- a cushioning material is characteristically interposed between the outer cylinder member and the insert fitting. That is, even if the resin outer cylinder member contracts, a gap is not formed between the outer metal member and the insert fitting due to the presence of the cushioning material.
- rubber is preferable as the cushioning material.
- the same rubber as the rubber elastic body is generally vulcanized and bonded between the mounting bracket and the insert metal fittings.
- the insert metal fitting itself in which the insert metal fittings are inserted in advance into the rubber elastic body molding mold is used.
- vulcanization bonding is performed simultaneously with curing of the raw rubber in the mold. And, if this raw rubber is made to wrap around the surface of the insert fitting, the cushioning material can be easily obtained.
- the raw rubber will pass through the hole to the surface of the insert fitting, and a rubber layer will be formed simultaneously with molding. Therefore, the rubber elastic body and the cushioning material are integrated by the hole of the insert metal fitting.
