Zusammenfassung:A hydraulic bushing assembly comprises an inner tube, a travel limiter surrounding the inner tube, a first intermediate insert, a second intermediate insert spaced apart from the first intermediate insert, and an elastomeric bushing disposed around the inner tube and encapsulating the first intermediate insert and the second intermediate insert. The elastomeric bushing at least partially encapsulates the travel limiter such that a portion of the elastomeric bushing is positioned between the travel limiter and the inner tube. First and second snubbers limit displacement of the travel limiter and define first and second fluid chamber within the elastomeric bushing. A fluid passageway defined by the elastomeric bushing and an outer tube extends between the first and second fluid chambers, wherein relative movement between the inner tube and the outer tube causes fluid transfer between the first fluid chamber and the second fluid chamber.
