Title:
VIBRATION ISOLATING DEVICE
Document Type and Number:
Japanese Patent JPS608540
Kind Code:
A
Abstract:
PURPOSE:To improve vibration isolating performance by constructing a pulse pressure generating means in such a way that a vibrating member made of a magnetic material is vibrated by means of a solenoid, in a vibration isolating device having said pulse pressure generating means which provides pulsation with the opposite phase to the pulsation generated by vibration, to a fluid in a fluid chamber. CONSTITUTION:In a mount unit 33 which supports brackets 31, 32, each of which is installed to a power unit and a car body respectively, a bag-like first elastic wall 39 is provided between a fitting member 35 and an annular rigid body 37 each fixed to brackets 31, 32 respectively. A board-like second elastic wall is provided on the lower-part opening end of a cylindrical frame body 38 fixed to the bracket 32, and a cylindrical case 41 having an annular groove 41b on its central part, is fitted in the cylindrical frame body 38 in a part over the elastic wall 40. A cylindrical vibrating member 42 made of a strong magnetic material is loosely fitted in an annular groove 41b in such a way that it can be displaced in vertical directions. And, the vibrating member 42 is vibrated by electrifyingly controlling upper and lower solenoids 45, 46 by means of a drive circuit 47 and based on the output of a crank angle sensor 49.
