起因している。 When attaching the strut suspension to the vehicle body, a coil spring placed around the outer periphery of the shock absorber is brought into direct elastic contact with the vehicle body, and an insulator is interposed between the shock absorber rod, that is, the end of the strut rod, and the vehicle body. It is considered desirable. This is because the insulator does not have to bear the load from the coil spring, so it is possible to use a rubber body with a smaller spring constant, which further improves vibration isolation.

is formed into an annular protrusion. The rubber body 13 is made to protrude diagonally outward from the upper and lower parts of the outer periphery, respectively, and comes into elastic contact with the upper and lower corner parts C and C of the box part 4, respectively, and is sheared and deformed by loads in the axial and horizontal directions. Annular upper and lower lip portions 16 and 17 are integrally molded, and an upper lip portion 16 is formed on the upper surface by covering the first sheet portion 14 and the second sheet portion 15.
The first stopper part 18 is lower than the protruding height of these upper and lower lip parts, and the first stopper part 18 is compressively deformed in response to an axial load. A second stopper portion 19 is formed which compressively deforms in response to a load.

The annular member 14a is concentrically fixed to the upper surface of the core member 11 with screws 20.

The seat portion 14 of the second stopper portion 19 is integrally cut, and the peripheral edge of the seat portion 15 of the second stopper portion 19 is made as the sheet portion 15 by utilizing the thickness of the core material 11.

られ、制振効果を十分に発揮できるものである。 According to the strut mount insulator of the present invention having the above configuration, only the upper and lower lip portions 16 and 17 respectively perform shear deformation to absorb high frequency vibrations in the axial and horizontal directions. Therefore, it has an excellent vibration isolation effect, and can withstand large loads in the axial direction and large loads in the horizontal direction when bouncing.
After the upper and lower lip parts 16 and 17 undergo shear deformation, the first stopper part 18 or the second stopper part 19 comes into pressure contact with the vehicle body side and is compressively deformed, resulting in a stopper effect in which the load-deformation characteristics of the insulator suddenly rises. is obtained, and the vibration damping effect can be sufficiently exhibited.

ことができるという実用効果を有する。 Therefore, since it is interposed between the upper end of the strut rod and the vehicle body side and satisfies both conflicting vibration isolation characteristics and vibration damping characteristics, it has the practical effect of further improving riding comfort.
