Bushing

The utility model discloses a lining which comprises an inner core, a shell, an inertia mass element arranged between the inner core and the shell, a first vibration reduction elastic body connected with the inner core and the inertia mass element, and a second vibration reduction elastic body connected with the shell and the inertia mass element. The lining is provided with a first moving space located between the inner core and the inertia mass element and a second moving space located between the shell and the inertia mass element. And the bushing is provided with a first limiting convex part which extends into the first movable space from the inertia mass element to the inner core and a second limiting convex part which extends into the second movable space from the inertia mass element to the shell. The static rigidity of the bushing in the specific radial direction is increased by arranging the first limiting convex part and the second limiting convex part, excessive displacement of a vibration system a
