Title:
SUPPORT DEVICE FOR POWER UNIT
Document Type and Number:
Japanese Patent JPS591830
Kind Code:
A
Abstract:
PURPOSE:To enable to absorb vibrations of high and low frequencies by keeping the spring characteristic of elastic bodies partitioning two fluid chambers mutually connected at a hard level at the time of low frequency vibration and at a soft level at the time of high frequency vibration. CONSTITUTION:Elastic bodies 12 and 13 are respectively arranged between a car-body side bracket 10 and a power unit 11, and in this construction, volumetric change rates of fluid chambers 14 and 15 are differentiated against the relative movement between the power unit and the car body. A liquid chamber 20 of an accumulator 17 is connected to the fluid chamber 15 via an electromagnetic switch valve 22, and the spring characteristic can be increased by closing the electromagnetic switch valve 22 and reduced by opening the same. This construction permits to obtain the sufficient effect of damping for vibrations of high and low frequencies.
