Abstract

A roll mount is provided and includes a rubber coupled to a core mounted in an exterior pipe coupled to an end of a main body, slits that are formed in the rubber at the periphery of the core, and a pocket that is disposed within the slits. The pocket includes a first pocket portion having a first and second chamber formed therein and connecting portions having flow paths that connect the first and second pocket portion and place the first and second chamber in fluid communication. A magnetorheological fluid is encapsulated in the first and second chamber, and flows therethrough, via the flow paths based on elastic deformation of the first and second pocket portion. The wound coils are disposed at exterior sides of the first and second pocket portions, and fluidity of the magnetorheological fluid is adjusted based on the electric current applied to the coil.

First claim

What is claimed is:

1. A roll mount comprising:
a rubber coupled to a core is mounted in an exterior pipe coupled to an end of a main body, slits are formed in the rubber at a periphery of the core, and a pocket is disposed within the slits, wherein the pocket includes:
a first pocket portion having a first chamber formed therein;
a second pocket portion having a second chamber formed therein; and
connecting portions that have flow paths that connect the first pocket portion and the second pocket portion and the first chamber and the second chamber are in fluid communication with each other,
wherein a magnetorheological fluid is encapsulated in the first chamber and the second chamber, the magnetorheological fluid flows through the first chamber and the second chamber via the flow paths based on elastic deformation of the first pocket portion and the second pocket portion, a coil is wound at exterior sides of the first pocket portion and the second pocket portion, and fluidity of the magnetorheological fluid is adjusted based on the amount of electric current applied to the coil,
wherein the slits are formed at a first side and a second side around the core, one on each side, respectively, the first pocket portion and the second pocket portion are detachably coupled to the slits, respectively, and an opening portion is formed to dispose the core between the first pocket portion and the second pocket portion, and
wherein the coil is disposed on upper surfaces of the first pocket portion and the second pocket portion, and wound in a spiral orientation that extends radially from a center of the opening portion between the first pocket portion and the second pocked portion.

2. The roll mount of claim 1 , wherein the coil is wound with the number of turns of the coil greater at portions where the coil is in direct contact with the first pocket portion and the second pocket portion than at portions where the coil is in indirect contact with the first pocket portion and the second pocket portion.

3. The roll mount of claim 1 , further comprising:
a second coil disposed on lower surfaces of the first pocket portion and the second pocket portion, and wound in a spiral orientation that extends radially from the center of the opening portion between the first pocket portion and the second pocket portion.

4. The roll mount of claim 1 , wherein the connecting portion is formed in an outward convex arc shape.

5. The roll mount of claim 4 , wherein the connecting portions include a first connecting portion that connects the first pocket portion and the second pocket portion at a first side with each other, and a second connecting portion that connects the first pocket portion and the second pocket portion at a second side with each other.

6. The roll mount of claim 5 , wherein a diameter of an exterior pipe connected to a rear end of the main body is smaller than a diameter of an exterior pipe connected to a front end of the main body, and the pocket is mounted in the exterior pipe connected to the front end of the main body.
