Liquid-filled type vibration damping structure
A liquid-filled type vibration damping structure is described comprising: a liquid-filled vibration isolator having (a) first and second frames respectively mounted on a vibration source and on the side of a vehicle body; (b) resilient member connected between the first and second frames; (c) a diaphragm secured to the first frame; (d) a baffle member secured onto the first frame and dividing an internal space surrounded by the resilient member, the diaphragm, and the second frame into first and second liquid chambers, the baffle member further having a hole and a first aperture for communicating the first and second liquid chambers with each other; (e) a holder cooperating with the baffle member to form therebetween an orifice portion communicated with the hole of the baffle member and having at least one aperture aligned with the first aperture of the baffle member; (f) a movable plate held by at least the holder between the apertures of the holder and the baffle member and moved with respect to the baffle member by the liquid flow through the apertures of the holder and the baffle member; and (g) at least one mass body attached into the resilient member to reduce the resilient coefficient. The structure further comprising: a bracket member for mounting the vibration isolator onto the vibration source at a predetermined angle of inclination with respect to the direction of vibration from the source; and the angle is sufficient to suppress the generation of a liquid column resonance peak.
