ABSTRACT:
A damper of a vibration damping system is installed to connect a power unit and a vehicle body and disposed independent from power unit mount devices. The damper is positioned in the direction of a tangent line of the direction of roll of the power unit. The damper consists of an elastomeric wall member defining a first fluid chamber and connected to the power unit, and an elastomeric diaphragm member defining a second fluid chamber which is communicated through a communication passage with the first fluid chamber. A liquid is filled in the first and second fluid chambers and the communication passage. The volume of the communication passage is changed in response to engine speed of the power unit, thereby effectively damping vibrations of the power unit in roll direction.
