A hydraulically damping mount includes amount core and an outer tube. In an embodiment, the mount core is supported on the outer tube via a mount spring of an elastomeric material, and the mount spring divides the space formed between the mount core and the outer tube into at least two fluid-filled chambers that are in fluid communication with each other via at least one damping channel and at least one decoupling channel. In an embodiment, at least one torsion-resistant decoupling device is movable back and forth by fluid flows and is arranged in the at least one decoupling channel. In an embodiment, the decoupling device is formed so that during a fluid induced movement of the decoupling device its inflow sides always face the fluid flows.

A tunable hydraulic vibration damping mount comprises a universal outer housing, inner sleeve, main spring assembly, bottom compliance assembly, and inner bushing. Each of a plurality of flow channel members comprises a cylinder having a common inner diameter, a common outer diameter, and a helical track having a cross-sectional area and a length defining a volume of the helical track. The helical track of each flow channel member defines a different volume. A selected flow channel member is positioned between the inner bushing and the outer housing and between the main spring assembly and the bottom compliance assembly. The selected flow channel member provides a selected dynamic performance of the damping mount.

In the present invention, any two of a second liquid chamber (27), a third liquid chamber (28), and a fourth liquid chamber (29) communicate with each other through a first restricted passage (31) formed in an outer attachment member (11), an inner attachment member (12) or a partition member (15), and the remaining one liquid chamber communicates with a fifth liquid chamber (32) formed in the outer attachment member (11), the inner attachment member (12) or the partition member (15), the remaining one liquid chamber is divided in a circumferential direction, and each of the liquid chambers divided in the circumferential direction and the fifth liquid chamber (32) separately communicate with each other through a second restricted passage (33) formed in the outer attachment member (11), the inner attachment member (12) or the partition member (15).

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 mount bush includes a tube member, a shaft member disposed coaxially with an axis of the tube member and having a coil, a first liquid chamber disposed at an upper side in an internal space between the tube member and the shaft member, a second liquid chamber in communication with a lower side of the first liquid chamber and containing a magnetic viscoelastic fluid, and a third liquid chamber in communication with a lower side of the second liquid chamber and having a porous body, wherein the coil is disposed such that a magnetic path that passes through the second liquid chamber in an orientation along at least one of an axial direction and a radial direction is formed through electrical conduction.

An elastomer bearing has an inner part, an outer sleeve that surrounds the inner part, and an elastomer body that is arranged between the inner part and the outer sleeve. The elastomer body extends from the inner part as far as the outer sleeve. The elastomer body comprises two liquid chambers, which are filled with a liquid and arranged one on top of the other in an axial direction, and a duct carrier arranged radially between the elastomer body and the outer sleeve. The duct carrier surrounds the elastomer body in a region of the liquid chambers and bounds the chambers. The elastomer body is vulcanized to the inner part. To reinforce the elastomer body, two, annular reinforcement inlays are embedded in the elastomer body, and form parts, separate from one another, of a cage that is embedded in the elastomer body.

A vibration damping device (10) comprises a tubular outer attachment member (11) and an inner attachment member (12); a pair of main rubber portions (13) that couple the outer attachment member (11) to the inner attachment member (12), and that are arranged so as to be spaced in an axial direction along a central axis (O) of the outer attachment member (11); and a partition portion (15) that couples the outer attachment member (11) to the inner attachment member (12), and that partitions a liquid chamber (25) between the pair of main rubber portions (13), in the axial direction, into a first liquid chamber (26) and a second liquid chamber (27). The partition portion (15) comprises an annular rigid portion (30) in which a restricted passage (33) that connects the first liquid chamber (26) to the second liquid chamber (27) is formed, and an annular elastic portion (29) that is adjacent to the rigid portion (31) in the radial direction. The elastic portion (29) is compressed and deformed in the radial direction and makes contact with the rigid portion (30) in an unbonded state.

The device includes solid force transmission elements including two reinforcements, a damping body, a damping space including a damping chamber, the device being normally in a filling state where the damping space is filled with a damping liquid and may accidentally be in a state of loss of filling, which has an integrated element, specific and proprietary, palliative for the loss of filling, inactive in the state of filling and made active in the state of loss of filling where they bring the hydroelastic device to a state of stiffness of a high level, such element including a locking system including a locking part, integrally rigid, and a deformable load part controlled by the state of the device with respect to filling.

A hydraulic transmission mount which isolates noise or vibration of an engine, the hydraulic transmission mount may include a core which moves horizontally together with a main rubber vulcanized outside the core in accordance with behavior of a vehicle; stoppers which are coupled to both surfaces of the core and define a hermetic liquid chamber with the core; a bracket which surrounds the stoppers and fixes the hydraulic transmission mount to a vehicle body; and a spoke which penetrates an insertion hole formed at a center of the core and has protruding regions that are bent at both end portions of the spoke and in contact with the stoppers, wherein a fluid encapsulated in the liquid chamber flows through the insertion hole in accordance with the behavior of the vehicle.

The present invention relates to a hydraulic bushing, including a main spring and a cylindrical outer housing. The main spring comprising: a core shaft; a first rubber body arranged on an outer wall of the core shaft, wherein two liquid chambers diametrically opposite to and spaced from each other are formed on the first rubber body, each liquid chamber extending throughout the first rubber body along an axial direction thereof; and a sleeve mounted on an outer wall of the first rubber body, a groove being formed in an outer wall of the sleeve. The main spring is disposed inside an inner chamber of the outer housing, and a flow channel for connecting the two liquid chambers with each other is formed between the outer housing and the sleeve through the groove.
