Vibration isolating device

Abstract

A vibration isolating device in which, even if the angular difference between a normal vibration input direction and a maximum input direction is greater, a pressure-joint section of an elastic body is not displaced from a specified position in a bracket tube section. [MEANS FOR SOLVING PROBLEMS] A rubber elastic body (18) is vulcanized and joined to the outer peripheral surface of an inner tube (16), end sections of a pair of pressure-joint sections (26) of the elastic body (18) are pressure-joined to the inner peripheral surface of a bracket tube section (12), and the elastic body (18) is pressure-fitted into a circular tube-like bracket tube section (12). Projection-like bends (34) projecting in an L shape with a height H greater than the plate thickness of the bracket tube section (12) are formed at those radially inner sections of the bracket tube section (12) that are in contact with the end sections of the pair of pressure-joint sections (26), the projection-like bends (34) being each formed in the axis direction (S), across the entire width of the bracket tube section (12).

Description

technical field [0001] The present invention relates to an anti-vibration device that prevents the crimping part of the elastic body from moving from a predetermined position in the bracket tube even when the angle difference between the normal vibration input direction and the maximum input direction becomes large, and particularly relates to a vibration-proof device for general industrial use. Anti-vibration devices used for machines, engine mounts of automobiles, suspension bushes for automobiles, etc. Background technique [0002] In the anti-vibration device used as an automobile engine mount, some devices have a rubber elastic body connecting a cylindrical outer cylinder and an inner cylinder disposed inside the outer cylinder, and a rubber elastic body fixed to the outer cylinder. bracket metal accessories. Such anti-vibration devices, for example, connect the inner cylinder to the engine as the vibration generating part, and use bolts or the like to connect the brac...

AI Technical Summary

Problems solved by technology

Therefore, if the height H of the protrusion 122 is processed to be greater than or equal to the thickness of the steel plate, a hole will be opened on the bracket barrel 112, so the height H of the protrusion 122 can only be made to be about the same as the plate thickness of the bracket barrel 112.
