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 bump stops 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.

A bearing bush and a method for producing a bearing bush are provided. The bearing bush includes a core element, an elastomer element, a cage element and a sleeve element. The cage element is at least partially embedded in the elastomer element. The elastomer element elastically connects the cage element and the core element to each other. The core element, the cage element and the elastomer element form a pre-assembly element. One of the sleeve element and the cage element includes a protrusion. The other of the sleeve element and the cage element includes a groove, which is engageable with the protrusion, in an assembled state of the bearing bush. The pre-assembly element is fixed in the sleeve element. The protrusion and the groove form a two-point contact in a cross-section.

A variable stiffness bushing includes: inner and outer tubular members; and an elastic member connecting these tubular members. At least one pair of liquid chambers axially separated from each other is defined in the elastic member. The liquid chambers are connected by a communication passage including a circumferential passage provided in one of the inner and outer tubular members. The one of the inner and outer tubular members includes a coil wound coaxially therewith and a yoke provided with a gap constituting the circumferential passage. A magnetic fluid fills the liquid chambers and the communication passage. Upper and lower end walls and an axially intermediate partition wall of the elastic member are configured such that when the tubular members are axially displaced relative to each other, a difference is created between volumes of the axially separated liquid chambers.

A formation method for liquid rubber composite nodes with middle damping holes is provided. The formation method includes adding a middle spacer sleeve between an outer sleeve and a mandrel, bonding the middle spacer sleeve and the mandrel together through rubber vulcanization, and assembling the integrated middle spacer sleeve and the mandrel into the outer sleeve; forming damping through holes which penetrate through the mandrel on the mandrel; hollowing the middle spacer sleeve to form a plurality of spaces; after vulcanization, forming a plurality of interdependent liquid cavities by using rubber and the plurality of spaces; and arranging liquid in the plurality of liquid cavities and communicating the plurality of liquid cavities through the damping through holes.
