rubber seat

Abstract

To provide a rubber mount with a novel structure capable of efficiently distributing input from a coil spring and preventing damage to a suspension member due to load concentration. It is equipped with an outer peripheral plate-shaped portion (16) that expands on the surface of the seat portion (46) of the suspension member (44) to receive the coil spring (52), and the inner peripheral portion of the outer peripheral plate-shaped portion is set along the suspension member. The erected portion (50) of the curved and erected ring-shaped curved portion (22), and on the inner peripheral side of the outer peripheral plate-shaped portion, the central protrusion (28) entering the positioning hole (48) of the suspension member is set as Protrude from the front end portion of the annular curved portion toward the base end side, and an annular groove (34) for inserting the erected portion is formed between the annular curved portion and the central protrusion. A flat-plate-shaped reinforcing member (14) located around the rising portion is embedded in a region deviated from the annular bent portion to the outer peripheral side.

Description

technical field [0001] The present invention relates to a rubber seat that overlaps with a suspension member and receives a coil spring in a cushioned manner. Background technique [0002] For a long time, in the suspension mechanism, there has been known a rubber seat that covers the seating portion of the suspension member that supports the axial end portion of the coil spring and receives the coil spring with a buffer. The rubber seat is sometimes formed only by a rubber monomer, but for example, a spring rubber seat is disclosed in Japanese Patent Application Laid-Open No. 2005-220976 (Patent Document 1), in which the The first fitting and the second fitting, thereby enabling tuning of the elastic properties. [0003] However, for example, when the vehicle is running, the coil spring expands and contracts due to irregularities in the road surface, and the input from the coil spring is transmitted to the suspension member via the rubber mount. Then, the rubber mount ela...

AI Technical Summary

Problems solved by technology

[0004] However, depending on the size of the load, there may be damage to suspension members and rubber mounts at the time of input

In particular, when the input from the coil spring is partially transmitted to the suspension member via the rubber seat, the suspension member may be damaged due to a locally large load

Specifically, for example, in the rubber seat described in Patent Document 1, when the position of the first fitting is shifted radially with respect to the fitted convex portion, the first fitting and the fitted convex portion are placed on the periphery. Partially approaching upward, the force is transmitted concentratedly, which may cause damage to the mated convex part
