Problems solved by technology

Regarding this anti-vibration device, in the figure, it is shown that the two ends of the inner cylinder are provided with a structure such as a flange, and the two ends of the inner cylinder are provided with a structure such as a stopper rubber, but its technical significance is not fully disclosed.
In addition, since the front end surface of the stopper rubber part is flat, the stopper rubber part comes into contact with the surface of the opposite stopper receiving part when the inner cylinder is greatly displaced, causing abnormal noise, etc.

Abstract

The present invention provides an anti-vibration device, which is easy to set the elastic constant within the range of small axial displacement of the inner cylinder, and can prevent the occurrence of abnormal sound during large displacement, and effectively Standing load-deflection curve. The anti-vibration device includes: an inner cylinder (12), an outer cylinder (14), and a body rubber part (16) combining the two; The edge part (18) and the small-diameter cylinder part (20) between the two flange parts constitute, and the body rubber part (16) connects the outer peripheral surface of the cylinder part (20) and the outer cylinder ( 14) are bonded between the inner peripheral surfaces, and a space portion (34) is ensured on the outer periphery of the flange portion (18), and a stopper rubber portion (24) is provided on the axial end surface of the flange portion (18). A plurality of protrusions (26) are provided on the front end surface of the stopper rubber part (24).

Description

technical field [0001] The invention relates to an anti-vibration device. Background technique [0002] Patent Document 1 described below discloses an anti-vibration device, which is arranged on the upper part of the shock absorber on the air spring device of the automobile, and is used to weaken and moderate the vibration transmitted from the shock absorber. . [0003] The anti-vibration device disclosed in Patent Document 1 is composed of an inner cylinder, an outer cylinder surrounding the inner cylinder, and a rubber elastic body sandwiched between the two cylinders. ) stopper and limit stopper, the outer cylinder is set to be shorter than the inner cylinder in the axial direction, and since the rubber-like elastic body is provided with a selection in the radial direction above and below the outer cylinder The part (Japanese: すぐり) constitutes a stopper mechanism that restricts the axial displacement of the inner cylinder between the two...
