Suspension insulator

A suspension insulator comprising:

• a bracket section configured to be coupled to a vehicle body, the bracket section defining an installation groove and a coupling groove;
• an inner core positioned in the installation groove inside the bracket section;
• a bushing module positioned in the installation groove inside the bracket section and surrounding the inner core, the bushing module having a passage part that contains a fluid;
• an outer pipe positioned inside the bracket section and surrounding the bushing module;
• and
• an upper section separate from the outer pipe that is inserted into and coupled to the coupling groove of the bracket section and configured to cover the bushing module,
• wherein the bushing module defines a groove in which the inner core is retained such that the inner core is spaced apart from the bracket section and the upper section, and
• wherein:
• the bushing module comprises a bushing that surrounds the inner core and includes a fluid storage part defining a fluid storage portion in which the fluid is stored, the bushing being made of an elastic material that enables elastic deformation of the bushing and the fluid storage part during movement of the inner core,
• the passage part is arranged with respect to the bushing such that the passage is fluidly coupled to the fluid storage portion, and
• the elastic deformation of the fluid storage part causes at least a portion of the fluid in the fluid storage portion to flow into the passage.
