A fluid-filled power unit mount device consists of a mount rubber securely interposed between two base plates. A partition plate is securely connected to one of the base plate so as to define fluid and auxiliary chambers on the opposite sides thereof. The partition plate is formed with an orifice to provide fluid communication between the fluid and auxiliary chambers, and provided with two parallely arranged movable mechanisms each having a movable member. The movable member is movable under small amplitude high frequency vibration causing booming noise, but restrained from its movement under large amplitude low frequency vibration, thereby effectively damping even vibration which is slightly higher in frequency than the booming noise generating high frequency vibration.

Fluid-filled power unit mount device

A fluid-containing power unit mounting device capable of effectively damping vibration in a wide range of frequency is shown. The damping function of the device is accomplished by a mounting rubber forming an internal fluid-containing chamber between a power unit and a chassis, a partition plate dividing the chamber and including a plurality of valve mechansims in series and an orifice communicating between both sides of the chamber.

A suspension arm for supporting an automobile wheel is joined with a gusset by two bushing means. The gusset is fixed to an automobile body to hold the suspension arm to the automobile body. Each of the bushing means is placed coaxially with the other in the fore and aft direction of the automobile and allows the suspension arm to turn up and down. Preferably, each of the bushing means comprises a bushing and a pin inserted into the bushing.
