Fluid filled engine mount unit

Abstract

Abstract PURPOSE:To absorb effectively the low frequency vibration as well as high frequency vibration in an engine mount unit in which a fluid chamber and secondary chamber, which are partitioned with each other by a partitioning plate, are filled with liquid, by providing a movable long cylindrical body in a through hole of the partitioning plate. CONSTITUTION:In a fluid-filled engine mount unit in which a hollow space 3 is provided in a mount rubber 4 fixed between a base plate 1 on the power unit side and a base plate 2 on the car body side, and a partitioning plate 6 equipped with a through hole 6a is installed on either side of the said two base plates, forming a fluid chamber 9 and a secondary chamber 10 at the both sides of the partitioning plate 6, a long cylindrical body 18 which opens its one end in the said fluid chamber 9 and the other end in the said secondary chamber 10 each independently, is movably installed in the said through hole 6a. Moreover, a stopper 19 is installed on at least one of the long cylindrical body 18 or the partitioning plate 6 in order to prevent the long cylindrical body 18 from coming out of the partitioning plate 6.
