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 hydraulic mount apparatus includes a housing defining a cavity. The apparatus also includes an annular member disposed in the cavity. The annular member is secured to the housing to split the cavity into a first chamber and a second chamber. The apparatus further includes a pressure relief apparatus coupled to the housing. The pressure relief apparatus is configured to allow fluid communication between the first and second chambers in response to a predetermined pressure threshold being reached in at least one of the first and second chambers. A suspension system including a shock absorber and a link is coupled to the shock absorber. The suspension system further includes the hydraulic mount apparatus coupled to one of the shock absorber and the link.

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.

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 vehicle vibration dampening mount assembly includes a housing, a resilient material, a sleeve and a solenoid. The resilient material has an outer portion attached to an interior surface of the housing and defines first and second chambers with a fluid passage extending therebetween. The sleeve is disposed within the housing and is attached to a central portion of the resilient material extending from a first end to a second end of the housing. The solenoid has a fixed portion mounted to the first end of the housing and a movable portion fixedly attached to the sleeve for movement therewith. The fixed portion has an electromagnetic coil arranged concentrically around the movable portion. The solenoid is configured to selectively move the moveable portion, the sleeve and the central portion of the resilient material in response to electrical current being provided to the electromagnetic coil.

A vibration absorber (1) with radially acting hydraulic damping has a bearing core (2). A bearing cage (4) radially surrounding the bearing core (2) and an elastomer body (18) resiliently connects the bearing core (2) and the bearing cage (4). An outer sleeve (24) radially surrounds the elastomer body (18) for connection to an absorber mass (40). At least two working chambers (28) to be filled with a damping fluid are formed in the elastomer body (18). The working chambers (28) are connected fluidically to one another by means of a dimensionally stable fluid duct (26).

A hydraulic mount apparatus includes a housing defining a cavity. The apparatus also includes an annular member disposed in the cavity. The annular member is secured to the housing to split the cavity into a first chamber and a second chamber. The apparatus further includes a pressure relief apparatus coupled to the housing. The pressure relief apparatus is configured to allow fluid communication between the first and second chambers in response to a predetermined pressure threshold being reached in at least one of the first and second chambers.

A suspension system including a shock absorber and a link is coupled to the shock absorber. The suspension system further includes the hydraulic mount apparatus coupled to one of the shock absorber and the link.

Disclosed is a hydraulic bushing and a rail vehicle. The hydraulic bushing comprises: a core shaft; a sleeve mounted on the core shaft, wherein a first rubber body is filled in a space formed between the core shaft and the sleeve, and a groove is provided on an outer surface of the sleeve; and an outer housing, which is mounted on the sleeve through press fit. Two liquid chambers for accommodating liquids are provided diametrically opposite to each other on the first rubber body, and the groove and the outer housing together define a flow channel, through which the two liquid chambers communicate with each other. Use of the hydraulic bushing on the rail vehicle not only can assure stable operation of the vehicle in a straight running state thereof, but also can reduce abrasion of a wheel and a rail in a curve running state.

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.

According to the embodiment of the present disclosure, a hydraulic bearing (1) is provided, comprising an inner core (2), an outer shell (3) which radially surrounds the inner core (2), an elastomer body (4) which resiliently interconnects the inner core (2) and the outer shell (3) in order to allow a relative displacement between the inner core (2) and the outer shell (3), a first working chamber (5) and a second working chamber (6) which are fluidically interconnected by means of a working channel, a bypass chamber (8) which is connected to the first working chamber (5) by means of a first bypass channel (9), wherein the first working chamber (5) and the second working chamber (6) are configured such that an amount of a volume change in the case of a displacement of the inner core (2) relative to the outer shell (3), in a predetermined radial direction, is larger for the first working chamber (5) than for the second working chamber (6).
