Title:
能動型防振装置
Document Type and Number:
Japanese Patent JP7028849
Kind Code:
B2
Abstract:
To provide an active-type vibration isolator which exerts stable attenuation performance and variable stiffness performance irrespective of a magnitude of a vibration amplitude which is inputted in an axial direction.SOLUTION: An active-type vibration isolator comprises: a first coil arranged at either of an inner cylinder and an outer cylinder; a second coil arranged so as to be aligned with respect to the first coil in an axial direction, and generating a magnetic field in a direction reverse to the first coil; a first magnetic body member arranged between the first coil and the second coil, and protruding to a liquid chamber; and second magnetic body members which are arranged in a pair so as to be aligned in the axial direction at the other of the inner cylinder and the outer cylinder. In the first magnetic body member, a tip part of the first magnetic body member faces a recess by protruding into the recess which is formed between the second magnetic members.SELECTED DRAWING: Figure 4
