DAMPER MOUNT FOR SUSPENSION OF VEHICLE

Japanese Patent JP3822292

B

PROBLEM TO BE SOLVED: To improve a damper mount for the suspension of a vehicle in such a way as by a simple structure, the isolation capacity for microvibration or noise is increased without impairing the damping response capacity of the damper. SOLUTION: The structure of a damper mount for a suspension of an automobile is such that a pair of rubber bushes 5 and 6 which are individually held by holding members 3 and 4 which has a general cup shape and a hole in bottom wall are mounted on a shaft part 2 of a damper, and the pair of rubber bushes 5 and 6 pinch a car body from upper and lower sides to couple the shaft part 2 of the damper with the car body. With respect to a shaft part insertion hole 9 punched in the car body, a gap is provided between the car body and the inner circumferential surface of the insertion hole 9 to insert the shaft part 2, the pair of holding members 3 and 4 are installed on the shaft part 2 with their both opening faces facing to the mounting face side of the car body, the outer surface of the bottom wall of one of the holding members 3 and 4 is fixed to the car body, the other holding member is fixed to the shaft part 2 in the same direction as one holding member, and at least the spring rigidity relative to the radial load of the rubber bushes held by one of the holding members is set low compared with the other rubber bush. Thus, an optimum tuning of the spring rigidity of the coupling part between a damper rod and the car body becomes possible.
