Abstract

A roll mount using a magnetorheological fluid may include a bracket which has a mounting portion having a pipe shape, an insulator made of an elastic material and fitted into the mounting portion, the insulator having therein two liquid chambers that are in communication with each other through flow paths and having a core coupled to a center thereof, and a coil which is wound around an outside of the insulator, in which a magnetorheological fluid is encapsulated in the liquid chambers, the magnetorheological fluid flows while the insulator is elastically deformed by a load applied to the core, and a flow rate of the magnetorheological fluid is adjusted depending on an amount of electric current applied to the coil.

First claim

What is claimed is:

1. A roll mount using a magnetorheological fluid, the roll mount comprising:
a bracket which has a mounting portion having a pipe shape;
an insulator made of an elastic material and fitted into the mounting portion, the insulator having therein two liquid chambers that are in communication with each other through flow paths and having a core coupled to a center thereof; and
a coil which is wound around an outside of the insulator,
wherein a magnetorheological fluid is encapsulated in the liquid chambers, the magnetorheological fluid flows while the insulator is elastically deformed by a load applied to the core, and a flow rate of the magnetorheological fluid is adjusted depending on an amount of electric current applied to the coil,
wherein a groove is formed in a metallic housing so that at least one strands of the coil wound on the metallic housing are taken out toward a side.

2. The roll mount of claim 1 , wherein the insulator is fitted into the metallic housing and mounted on the bracket, and the coil is wound around an outer circumferential surface of the housing.

3. The roll mount of claim 2 , wherein the liquid chambers are positioned at both sides of the core interposed therebetween.

4. The roll mount of claim 1 , wherein the liquid chambers are positioned at both sides of the core interposed therebetween.

5. The roll mount of claim 1 , wherein the flow paths are formed at both sides along a circumference of an inner circumferential surface of the insulator between the liquid chambers.

6. The roll mount of claim 1 , wherein the liquid chambers are positioned at both sides of the core interposed therebetween.
