摘要： PURPOSE:To maintain a toe-in tendency and reduce axial displacement. CONSTITUTION:An outer cylinder fitting 12 is press-fitted into the base end side of a trailing arm 24 for connection. An inner cylinder fitting 16 is disposed on the inside of the outer cylinder fitting 12, and a protruding plate 18 is provided at the end part of the inner cylinder fitting 16. An elastic body 14 made of rubber is disposed between the outer cylinder fitting 12 and the inner cylinder fitting 16. An elastic body 14 is vulcanization-bonded also to a protruding plate 18 and the flange part 12B of the outer cylinder fitting 12. When force along the axial direction of the outer cylinder fitting 12 is applied, since the protruding plate 18 is opposed to the flange part 12B, the elastic body held by the flange part 12B and the protruding plate 18 is pulled to absorb force, so that large displacement is not generated in the axial direction.

摘要： PURPOSE:To enhance the durability by providing elastic wall parts facing a plurality of small liquid chambers, which are expanded and contracted with displacement between an inner and an outer cylinder and put in communication through a restriction passage, bending these elastic wall parts in the direction of expansion and contraction of the small liquid chambers, and thereby preventing generation of great defoliating force. CONSTITUTION:An inner cylinder 30 and an outer cylinder 32 are arranged coaxially, and an intermediate cylinder 34 is fixed inside this outer cylinder 32 through an elastic member with small wall thickness 36. Between this and the inner cylinder 30 a cylindrical elastic member 38 is set over, and small liquid chambers 40, 42 are filled with the liquid and in communication with the periphery of the intermediate cylinder 34 through a ring-shaped recess. The periphery of this recess is shut by the outer cylinder 32 to become a restriction passage 44, and serves as a moving path when either of the small liquid chambers 40, 42 has an increased pressure. A stopper 46 protruding to the small liquid chambers 40, 42 is fixed at the periphery of the inner cylinder 30 covered with a small wall thickness part as extension of the above-mentioned elastic member 38, to perform restriction of the amount of motion when the inner 30 and outer 32 cylinders make relative movement. Thus no major stresses are concentrated on the elastic members constituting liquid chamber even at the time of relative movement between the inner and outer cylinders to ensure that the elastic members are installed certainly and the durability enhanced.

摘要： PURPOSE:To ease the assembling work of the captioned isolator by providing an actuator, which enables to open or close a connecting passage for fluid chambers that are situated between an inner cylinder and an outer cylinder and that are connected with each other by means of an elastic body, and connecting the fluid chambers by means of a small-diameter passage that is provided separately from the said connecting passage. CONSTITUTION:Two fluid chambers 4 filled with fluid are formed at a space between an inner cylinder 1 and an outer cylinder 2 which are connected with each other by an elastic body 3, so that a connecting passage 5 can be opened or closed by an actuator 6. In addition, when the vibration is not transferred at all, a small-diameter passage 7, which is provided separately from the said connecting passage 5, allows the fluid in the fluid chambers 4 to flow through the passage 7. With this contrivance, a constant and smooth operation of the vibration system can be achieve, thereby reducing the man-hours required for the assembling work.

摘要： PURPOSE:To enable the shortage of a pipe having small effective area by supplying fluid into a hollow chamber 18 of the main body of a vibration absorber which is made of resilient material, making the communication of both said pipe and the hollow chamber, and inserting a mass body having a greater density than said fluid into said pipe. CONSTITUTION:A cylindrical resilient boby 16 is bonded between a base plate 12 and a top plate 14 with vulcanized rubber. A hollow chamber 18 which is defined by those plates is to be used as an air chamber. One end of a pipe member 22 is communicated with the base plate 12 and the other end thereof is open to the atmosphere. A spherical mass body 24 is disposed inside the pipe member 22 and is able to be moved in the longitudinal direction of the pipe member 22. Vibration generated in an engine therefore acts to the resilient body 16 via the top plate 14 so that air column resonance is produced inside the pipe member 12 to absorb the vibration. By having the mass of said mass body 24 greater than air mass inside the pipe member 22, resonance can be apropriately produced to absorb the vibration even if the pipe member 22 is short.

摘要： PURPOSE: To facilitate manufacture by simple construction and reduce the manufacturing cost by adjusting fluid resistance of liquid in a slender restricted passage so as to obtain damping effect due to liquid column resonance against vibration of various frequencies input from a vibration generating part. CONSTITUTION: Vibration generated in an engine is transmitted to a liquid chamber 13 through a vibration absorbing main body 10, electroviscous fluid in the liquid chamber 13 is moved through an orifice 18, and the vibration is absorbed by the passing resistance. An electrode plate 21 and the outside wall 24 of the lower end part of an outer cylinder 9 are made to carry a current through lead wires 22, 22A, viscosity of electroviscous fluid in the orifice 18 is adjusted, and because the orifice 18 is formed along a circular-arc-like protruded part 6 into a slender shape of long axial measure, even if engine vibration is generated extending over a wide range of frequency, various liquid column resonance vibration absorbing effects corresponding to these are obtained. In this way, manufacture is facilitated by simple construction and the manufacturing cost is reduced.
