Abstract

An assembling device for a bush may include: a bush unit mounted on a part; a connection unit of which the inside is locked and fixed to the bush unit; and a support unit coupled to the connection unit, and supporting the bush unit so as to prevent separation of the bush unit.

First claim

What is claimed is:

1. A suspension system of a vehicle comprising:
a bush assembly comprising an inner pipe extending along an axis, an outer pipe generally concentrically surrounding the inner pipe, and an elastic body inserted between the inner and outer pipes such that the elastic body has an end portion surrounding the inner pipe when viewed in a direction along the axis;
the end portion of the elastic body comprising an annular recess depressed into the elastic body in the direction along the axis such that the annular recess defines an inner sidewall that surrounds the inner pipe and faces away from the inner pipe;
the end portion of the elastic body comprising a flange protruding from the inner sidewall into the annular recess and away from the inner pipe;
a bush support comprising a support bottom and a support sidewall, the support bottom comprising at least one plate, a central opening and a plurality of peripheral openings that are radially outside the central opening, the support sidewall extending from the at least one plate and comprising a plurality of holes; and
a bush coupler comprising a ring-shaped body and a plurality of protrusions extending from the ring-shaped body, the ring-shaped body comprising an inner sidewall and an insertion groove formed on the inner sidewall;
wherein the ring-shaped body of the bush coupler is at least in part received in the annular recess of the end portion of the elastic body such that the inner sidewall of the ring-shaped body opposes the inner sidewall of the end portion and further such that the flange protruding from the inner sidewall of the end portion is inserted into the insertion groove formed on the inner sidewall of the ring-shaped body,
wherein the bush support is placed over the inner pipe and the end portion of the elastic body such that the central opening of the support bottom is aligned with the inner pipe, such that the plurality of the peripheral openings of the support bottom are aligned with the annular recess of the end portion of the elastic body, and such that each of the plurality of coupling protrusions of the bush coupler passes one of the plurality of peripheral openings of the support bottom and is received by a corresponding one of the plurality of holes.

2. The suspension system of claim 1 , wherein the support bottom abuts an end portion of the inner pipe.

3. The suspension system of claim 1 , wherein the outer pipe and the inner pipe are formed of a metallic material.

4. The suspension system of claim 1 , wherein the bush assembly is mounted on a front-wheel member or rear-wheel member of a vehicle.

5. The suspension system of claim 1 , wherein the bush support further comprises a top annular flange extending from the support sidewall, the top annular flange surrounding the support bottom when viewed in the direction along the axis.

6. The suspension system of claim 1 , wherein the plurality of peripheral openings are connected to the central opening.

7. The suspension system of claim 1 , wherein the bush coupler is a plastic coupler.
