Liquid-encapsulated damper mount and hydraulic damper mounting structure in suspension of automobile
Patent number: 6776402Abstract: A mount for an upper portion of a vehicle damper suspension includes an elastic member interconnecting a bracket fixed to a vehicle body and a bracket fixed to a damper rod protruding from a damper case and formed into a tubular shape to surround an outer periphery of an upper portion of the bracket, a first liquid chamber defined in part by the elastic member, and a second liquid chamber defined in part by a diaphragm communicate with each other through a communication passage. The elastic member is shear-deformed vertically with the vertical movement of the damper rod. Thus, it is possible to reduce the vertical dimension of a damper mount, while ensuring a large amount of change in the volume of the first liquid chamber, as compared with a conventional damper mount in which the block-shaped elastic member provided at the upper portion of the damper case is deformed under compression or tension, to thereby change the volume of the first liquid chamber.Type: GrantFiled: November 19, 2001Date of Patent: August 17, 2004Assignees: Honda Giken Kogyo Kabushiki Kaisha, Hokushin CorporationInventors: Yasuo Miyamoto, Masashi Furuya -

Patent number: 6676101Abstract: A horizontal-motion vibration isolation system for supporting an object in an equilibrium position relative to a base while suppressing the transmission of horizontal vibratory motion between the object and the base includes a plurality of columns, each column having a rigid member with a first end and a second end. A tilt mechanism is operatively connected to each first end of the rigid members and the object.
