<p>PURPOSE:To control the various input vibration effectively by providing an elastic bush, which can tune the damping characteristic in a wide range, as an elastic bush, in which an inner and an outer cylinders are relatively displaced to the rotation direction at the time of transmission of the vibration to control the vibration thereof. CONSTITUTION:An elastic bush, in which an inner cylinder and an outer cylinder are connected by an elastic body, is provided with a damping mechanism for generating the damping force with deformation of the elastic body. Multiple damping mechanisms which consist of each liquid chamber 16, 16, 17, 17, of which volume is changed by the deformation of rubbers 14, 15 for connecting the inner cylinder 11 and an intermediate cylinder 13, and the intermediate cylinder 13 and the outer cylinder 12 to each other with relative displacement of the inner and the outer cylinders to the rotation direction, and orifices 18, 19 and 22, 23 for communicating these liquid chambers are arranged in series between the inner cylinder 11 and the outer cylinder 12.</p> |
