Liquid-encapsulated damper mount and hydraulic damper mounting structure in suspension of automobile

摘要

An elastic member interconnecting a bracket fixed to a vehicle body and a bracket fixed to a damper rod protruding from a damper case is 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.
