ABSTRACT:
An upper mounting structure for a wheel suspension includes a coil spring and a strut assembly each of which is adapted to be connected at its lower end with a wheel, while an upper end of the coil spring is coupled with a vehicle body through a spring insulator of high stiffness and an upper end of the strut assembly is coupled with the vehicle body through a strut mounting insulator of low stiffness. The structure further includes an additional insulator connecting between the upper ends of the coil spring and the strut assembly, which additional insulator has higher stiffness than the spring insulator within higher frequency range. Therefore, the strut assembly is capable of absorbing a surge vibration of the coil spring within the higher frequency range in spite of low stiffness of the strut mounting insulator.
