The present disclosure provides an engine mount for a vehicle. The engine mount includes a rubber assembly that is connected between a vehicle body and an engine. A fluid sealing assembly is detachably assembled to the rubber assembly, allowing tuning of the engine mount to be performed by detaching the fluid sealing assembly while the engine remains connected to the engine mount.

A liquid composite spring and a method for adjusting stiffness and damping property of the liquid composite spring such that the liquid composite spring includes an outer sleeve; a core shaft arranged around an upper portion of the outer sleeve. An upper portion of the core shaft is located inside the outer sleeve, while a lower portion extends out of the outer sleeve; an upper liquid chamber formed in an upper space inside the outer sleeve and having a lower portion connected to a top end of the core shaft; and a lower liquid chamber formed in a lower space inside the outer sleeve and connected with the core shaft. The core shaft has a damping flow channel arranged therein, for communicating liquid in the upper liquid chamber with liquid in the lower liquid chamber. The liquid composite spring can provide vibration-reducing effect and change stiffness and damping effect.

A fluid-filled tubular vibration-damping device including: an inner shaft member and an outer tube member connected by a main rubber elastic body defining a non-compressible fluid filling region partitioned into two axially-opposite fluid chambers connected by an orifice passage, by a partition wall rubber fixed to a side of the inner shaft member in an inner periphery thereof and inserted in a side of the outer tube member at an outer periphery thereof so that the partition wall rubber is axially movable relative to the side of the outer tube member; a seal tubular part formed integrally at the outer periphery of the partition wall rubber to axially protrude to opposite sides; and a thicker annular fitting part formed integrally at each protruding tip of the seal tubular part, and fitted in the side of the outer tube member, slidably along it.

A hydraulic body mount with a combined rubber cushion and a hydraulic module may include an inner shaft, a mounting plate, a mounting bracket, a main rubber element, an inner ring, a fluid track, an upper bellows, a washer, a lower bellows, an outer can, a rate plate, a lower bushing, a crash washer, a doubler plate, and a retainer bracket. The fluid track may be configured to receive a fluid via a fluid port. The upper and/or lower bellows may be configured to interact with the fluid. The rate plate may be configured to engage the lower bushing and may be deformed when receiving the at least a portion of the inner shaft.

A liquid-filled bushing (1) includes an inner tube (11) and an outer member (12). The outer member (12) defines a pair of liquid chambers between the outer member (12) and the inner tube (11), and an orifice portion (13) in which an orifice passage (24) which communicates with the liquid chambers is formed. An elastic body (14) which elastically connects together the orifice portion (13) and the inner tube (11) is provided. The pair of liquid chambers are individually disposed on both sides between which the inner tube (11) is interposed. A first protrusion portion (11a) which protrudes outward in the radial direction and is fitted into the elastic body is formed in the inner tube (11), and a second protrusion portion (28) which protrudes inward in the radial direction and is fitted into the elastic body (14) is formed in the orifice portion (13). The first protrusion portion (11a) and the second protrusion portion (28) are disposed in both portions between the pair of liquid chambers adjacent in a circumferential direction such that positions of the portions in the circumferential direction coincide with each other and positions of the portions in the direction of the center axis are different from each other.
