Abstract
A bushing for a trailing arm may include an inner rod having a plate shape, a body in which a central portion of the inner rod is disposed, a reinforcing material disposed to surround an outer surface of the body, a first elastic member in which the reinforcing material is disposed, a second elastic member disposed around the first elastic member, and an outer steel member disposed to surround the first elastic member and the second elastic member. The reinforcing material may be disposed between the outer surface of the body and an inner surface of the first elastic member.
Claims19
A bushing comprising:
- a body;
- an inner rod configured to be coupled to a vehicle part and disposed in a central portion of the body that surrounds a central portion of the inner rod;
- a reinforcing material disposed to surround an outer surface of the body;
- a first elastic member comprising a coupling hole in which the reinforcing material and the body are disposed;
- a second elastic member disposed around one or more portions of the first elastic member;
- and
- an outer steel member disposed to surround the first elastic member and the second elastic member,
- wherein the reinforcing material is disposed between the outer surface of the body and an inner surface of the first elastic member, and
- wherein the body has a plurality of stopping protrusions configured to locate the reinforcing material therebetween, and each of the plurality of stopping protrusions has a coupling recess into which a coupling protrusion of the first elastic member is configured to be inserted.
A bushing comprising:
- an inner rod configured to be coupled to a vehicle part;
- a body in which a central portion of the inner rod is disposed;
- a reinforcing material disposed to surround an outer surface of the body;
- a first elastic member comprising a coupling hole in which the reinforcing material and the body are disposed;
- a second elastic member disposed around one or more portions of the first elastic member;
- and
- an outer steel member disposed to surround the first elastic member and the second elastic member,
- wherein the reinforcing material is disposed between the outer surface of the body and an inner surface of the first elastic member, and
- wherein the central portion of the inner rod comprises a fixing hole.
An apparatus comprising:
- an inner rod configured to be coupled to a vibrating part;
- a body in which a central portion of the inner rod is disposed;
- a reinforcing material disposed to surround an outer surface of the body;
- and
- a first elastic member comprising a coupling hole in which the reinforcing material is disposed,
- wherein strength of the reinforcing material is greater than strength of the body and strength of the first elastic member, and
- wherein the central portion of the inner rod comprises a fixing hole.
